What Is A DIY Solar Generator And Who Is This For


A solar generator is a compact and small box composed of three primary components: the batteries, the charge controller, and the inverter. The generator is responsible for drawing the sun’s energy via the solar panels, and then this absorbed energy is stored in high-capacity cells or batteries.

With the inverter’s help, the stored energy from the sun is released when you power your electrical devices and start charging your laptops, smartphones, and other devices in your home or recreational vehicles.

A DIY solar generator is an alternative option if you don’t want to purchase those ready-made and ready to install generators in your home. This solar generator is something you build and are perfect for RVs, campers, trailers, and boats.

Today, there are solar generator kits where everything you need to make your solar generator is already included. You’ll be looking into your actual solar panels, batteries, inverters, wires, racks, mounting hardware, and other parts to complete your project.

All you need is to assemble it, and you’ll have your generator in only half a day. What makes this appealing to most homeowners is that you enjoy the advantages of the commercial solar generators but with lesser costs, since you can fully customize it to your needs. You can have a say with the materials you like to use and tailor it to your budget.

Do it yourself solar generators are also a big hit for those homeowners, RVers, boondockers, and outdoor enthusiasts who are not ready yet to commit to the commercial solar generators. They may just want to feel the advantages before lunging full time and either buy a new one or a bigger one.

It is also for folks who also enjoy DIY projects at home to continuously challenge themselves and explore what they are capable of doing with results that would have significant advantages.

These bundled kits will be an excellent step for families who would want to save a couple of bucks off their electricity bill while using the sun’s free power and those who are not so keen on the harmful effects of diesel and petrol-fuelled generators on the atmosphere.

How Does It Work

Both DIY and commercial solar generators follow the same principle of how it works. It is composed of three primary components which are:

  • The battery is where the solar generator saves and stores the energy that is being captured from the sun. This is a reservoir of the sun’s energy. Usually, lithium-ion cells are being used in generators, but you can also opt for lead-acid ones.
  • Inverter – its primary responsibility is to convert the low Direct Current (DC) power from the battery cell into Alternating Current (AC) that is usable by your AC devices. DC devices and gadgets can bypass the inverter since it doesn’t need the current to be converted. It can use the “raw” form of the current.
  • Charge controller – This component aims to shelter and uphold the stability of the solar generator’s battery. This is considered the brain of your solar generator and can have different associated attributes that are related to the discharging and charging of your battery.

With the three main components briefly introduced, the solar generator functions by catching and taking the sun’s energy via your solar panels. Then, it is stored in your batteries. This energy will then be converted as needed into AC power or leave it as raw power via your inverter before it gets released and becomes usable in your home, cabins, boats, or recreational vehicles.

Your solar generator kick starts the whole process as it initially captures the sun’s solar energy. Without these accumulated energies, your inverter can’t do so much because it doesn’t have anything to process.

What Are The Different Types Of DIY Solar Generators


It would be most suitable to know which kind of solar generator you need so your DIY project can achieve its purpose and make the most out of its functionality. There are three basic kinds of solar generators that you can decide on, each with its pros and cons.

Practical for large-scale appliances like refrigerators, air conditioners, and television is the solar backup generator. There is usually a series of backup generators working with a power station system. Considering the maximum alternator wattage ranking, these are primarily designed for emergencies when there are power outages. Yes, it is powerful, heavy, and also expensive.

Meanwhile, a portable solar generator is considered the most versatile and lightweight among the kinds of solar generators and is ideal for small appliances like cameras, laptops, and cordless tools. It usually comes with straps or handles, making it easy to carry around. Unfortunately, they are limited to small electrical devices and can only power up or charge large appliances on a limited time.

Frequent recharging is required to prolong the functionality of a portable solar generator. Most folks new to solar power opt for this kind of solar generator because it is relatively economical and is considered a good investment. RVers and outdoor enthusiasts tend to have this at all times when off-grid because it allows them to have just sufficient power during their adventures. It is portable and reliable.

The last kind is called a smart solar box. It is a programmed generator that adjusts energy based on its condition. Some folks would prefer this because it can save you time from doing the manual calibration.

Going through these kinds of solar generators can direct you to precisely what you need. It will also be helpful if you take the time to assess your needs and the electrical devices and gadgets you have and will be using solar energy.

Advantages And Disadvantages Of Using A DIY Solar Generator

Do-it-yourself solar generators do a fantastic project because it is easy to assemble and install, but it also has more advantages for its users. It is intriguing to take a closer look to find out if it is something that you and your lifestyle can work with. For sure, you’ll find that with its advantages, it is worth the build.

Here are some of the many advantages of DIY solar generators:

  • Flexible – DIY solar generators don’t restrict you with options and provide you with more flexibility depending on your energy consumption and needs. It will be entirely up to you how many batteries you will be using and the number of solar panels to meet your needs. These decisions would directly impact your charging capacity and charging time.
  • Power – depending on your choices, you can create and assemble your solar panel and make it even more powerful than the conventional ones. There are expansion kits available that can allow you to upgrade your system to 400W or the maximum allowable specific to your solar panel manufacturer.

When you are out camping or spending time in your RV, one of your most significant worries is the power since the grid can’t be as accessible as you want it to be. Here is where DIY solar generator kits come into play because you can have it with you wherever you are with as much needed power as required.

  • Expandability – DIYs don’t just give you the option to add more solar panels and reduce solar panels depending on your need. You can easily change your setup in a fraction of time without additional costs or too much layout modification.

Unlike the commercial solar generators where you have to get a new one, if you want a bigger or smaller solar panel, DIYs don’t get you stuck with this problem. The capacity is entirely your decision to make, and you can make modifications based on your needs using your original layout and materials. You can start with a primary solar generator and eventually expand to a working 3000-watt portable solar generator.

  • Self-satisfaction – there is always a geek in everybody, and being able to create something from scratch and use it will get that alter-ego happy.

As always, where there are benefits, there will also be some drawbacks with DIY solar kits. It can still be a daunting experience to choose which brand you want to invest in. Although it is relatively cheaper than the commercial ones, it still needs to be planned in your budget. If you don’t have the necessary skills in wiring, you might require professional help, so your choice of panel kit won’t go to waste. Lastly, DIY or not, solar generators are 100% dependent on the sun, which you have no control whatsoever.

How We Picked And Tested


Buying your solar generator, especially if you plan to make one yourself, can be a little intimidating. Even certified DIYers want to choose the right starter set, so the chances of success are higher. You can make this process easier by considering some factors when picking your solar generator.

You don’t just settle for whatever is available, but you have to make sure that when you have completed your little project, you will be able to use it, and you can reap the benefits. It takes a bit of effort to learn and be more knowledgeable about solar power, but it pays off because, as the famous saying goes, “Knowledge is Power.” Here are a few things you can look at when shopping:

Capacity – your generator’s capacity will identify the amount of energy that your generator can keep or store when there are very limited to zero sources of sunlight. An example would be when the night falls or during the winter season when there is the minimal sun. How much can your generator supply to your devices, and how long can it steadily supply the energy?

You might be tempted to get the solar generator with the largest capacity. Still, it’s top-tier first to identify your power consumption and the number of devices and appliances that are being used to have a good idea of the ideal capacity to purchase. Some online calculators can help you with this aspect less the complicated math required.

Portability – one primary reason you’d want to buy or build your solar generator is that you want to have power when you are off-grid. Let’s admit it. Heavy-duty batteries are heavy and big, so to help you increase that portability rating. You might need to compromise with a more portable solar generator while reducing its capacity. Note that in this aspect, you look into the construction of your solar generator carrier too.

It has to be built with portability in mind. You’ll be looking into bringing it along with you during hikes and treks, moving it from one van to another truck. You don’t need the extra weight, but what you need is the power stored in that generator.

Reliability – there are some established brands that you can initially put on your list when shopping. Although most of these reputable manufacturers are pricey, you downright get reliability and quality from them.

In other words, they are already ‘proven and tested’ when it comes to the industry, so they know their business well as well as the needs of the consumers. Building your DIY solar generator with components all with no name at all is pretty risky and shady. If your budget is a bit tight, go for at least for brands that are about middle-quality caliber.

With these three things considered, you can build your solar generator. The ultimate way to test it is to get it outside under direct sunlight and look into the reading if your solar panels are absorbing the sun’s energy and the generator storing it into the batteries. If you can power up your devices, then you can consider it a successful project. Some tweaks might be needed eventually, but you are looking into a promising solar future.

Frequently Asked Questions


How do you make a homemade solar generator?

Making your own DIY solar power generator can be a project that you’d surely enjoy. It is something functional, and with so many advantages, you can be mighty proud of your creation and reap its benefits. While some homemade solar generators might need specialized tools and steps, here are the steps necessary to start you with. You can simply proceed from these guidelines to get the answers on how to build a solar generator:

  • Prepare your essentials – this includes your battery, the battery box, the charge controller, an inverter, and a DC input device. Make sure that you know which battery you need by identifying the amount of energy you want to save. Typically, solar generators utilize 12V batteries, but lithium-ion and lead-acid cells are great choices too.
  • Prepare your battery box – identify where you want your outlets and DC meter to be laid-out. Consider the placement so you can easily read and access it anytime without needing to move things around. This is also the time to strategically determine where your plugs, chargers, and other accessories will be laid out next. Once you have finalized the layout, you can start drilling and installing your outlets, including the DC meter.
  • Connect the electrical parts – once the DC meter and the outlets are drilled and in place, set your battery in your battery box. With insulated wires, join your DC meter to your battery terminals. Work with the negative terminals first before proceeding with the positive stations. You can already connect your solar panel to your battery, and the connection can either be made permanently or temporarily.

For a permanent connection, connect your solar panel directly to the battery, like how you did with the other components. If you opt for a temporary one, you can just join plugs to easily connect in your solar panel either at the front or the rear of your battery box. This third step should make the wiring of your solar panel complete.

  • See if your solar panels work – this is ultimately testing if your DIY solar generator kit works, so strategically place it outside so it can receive as much energy from the sun. If it is possible to make use of solar panel wires that are longer, it would be easier for you because you don’t need to bring your battery box outside.

You can just keep it in place and prevent it from being exposed to the natural elements. Note that it is only the panel that needs direct exposure to the sun. After a few hours of direct sunlight, check the reading of your DC meter. The voltage that you are getting should now be numerically available. Leave your panel outside as needed so you can charge it to its maximum capacity.

  • Start using your homemade solar generator – once you have charged up your generator, you can start to power your electrical appliances. Quick connections come in very handy at this stage since you can just keep your DIY generator mounted where you require it and connect it to the corresponding receptacle.

The observation also commences at this stage as you need to monitor the length of time it takes for one appliance to fully charge and note how much power you have left after charging. By getting this info, you can have an overview of time and energy consumption to plan around it smarter.

With these necessary and starting steps, you can continue expanding your solar generator. Next time, your question won’t just be on how to create a primary solar generator but how to build a 5000 watt solar generator.

What size solar generator do I need?

A solar generator can only be as effective when you are using the correct size. Sure, a lot would say that the larger your solar generator is, the better while a smaller generator would require constant modifications.

To identify the correct solar generator size for you, you can follow the general rule of the generator twice the size of your inverter’s continuous and constant output. An example would be a 2,000-watt inverter that should work with a 4,000-watt generator.

It is also good to consider some round-ups to give some room for your generator’s tendency to lose some power. This can happen when you are situated in higher elevations. Some engines tend to suffer 3% of their energy for every 1,000 increase in altitude.

Aside from the technicalities, you should be able to identify your power consumption on a daily and monthly basis and, at the same time, know how much power stored you have. The power stored will be the energy that your solar panels are capable of providing to your cells. With this, you can have better solar panel efficiency and make the most of your solar generator’s many benefits.

What is the cost of a 200 watt DIY portable solar power generator?

The cost of 200-watt homemade solar generators depends on whether they are ready-to-assemble kits or individually-purchased components you must build from scratch.

Many DIY solar power generator kits are available on leading e-commerce platforms, especially Amazon. Buyers can pick trustworthy brands, such as Renogy (about $350) and DOKIO (about $225). With patience and diligence in your search, you could buy a DIY solar generator kit for under $200.

Although kits make it more convenient to produce a homemade generator, their specifications might not suit your electrical requirements. Hence, making a solar generator from scratch makes perfect sense.

You could check solar generator plans to create the most suitable system for home applications. After all, this type of device only needs five principal components – solar panels, a battery, an inverter, a charge controller, and a DC input device.

A 100-watt solar panel can cost you $100 to $200. Most of these products already have an integrated charge controller. You can get a solar battery for about $50 to $60, while an inverter can cost you $50. A cheap battery box and DC input device cost about $10 each.

Is it cheaper to build your own solar generator?

Building a portable solar generator DIY style could be cheaper than buying a kit to assemble.

It is possible to spend less than $300 on this project if you pick affordable yet good-quality components. Of course, if you’re building a 10,000 watt solar generator, you might end up with a costlier project than purchasing a ready-to-assemble kit.

How long does a DIY solar generator last?

The longevity of a DIY solar battery generator depends on the quality of the individual components, especially the battery, solar panel, inverter, and charger.

High-quality monocrystalline solar panels can last up to four decades, while similar-quality polycrystalline versions can operate for up to 35 years. Solar batteries have an operating lifespan of five to 15 years, while charge controllers can last 15 years. On the other hand, solar inverters have a 10- to 12-year lifespan.

How to use it?

Suppose you are new to solar panel. In that case, your initial questions will revolve around the how’s, like how to build a 3000 watt solar generator” or how to make sure the wirings are correct. But if you have successfully created your DIY project, you will transition to finding out how to use your solar generator effectively. Technically, after the build phase of your solar generator, there is nothing much you can do because it will function automatically already.

Using your solar generator is relatively simple. Solar generators rely heavily on your solar panels, so you use it by directly exposing your panels under direct sunlight. You can strategically place them where it can get the maximum photons.

Once your solar panels have absorbed the sun’s energy, your generator works on its own already. It will let the inverter do its job and make the necessary energy transitions, and from there, your generator can provide power to your appliances and devices like normal.

You can use your solar generator at home, but mostly when you go off-grid. You can have a more enjoyable experience while in outdoors when you know that your smartphone is sufficiently powered to capture your adventures and memories or wake up to a newly brewed cup of coffee. You can simply connect your electrical devices to your solar generator and enjoy the day.

Most generators have a wide array of outlets and even USB ports, so you can be sure that you have a slot for your devices and appliances.

There is some DIY solar generator cheap as well that is so lightweight that you can carry the solar panels around while you are spending the day under the sun, so while doing that, your solar generator is already working. By the time you get home or find yourself in a clearing, you can just use your solar generator and add a few more power to your phone or camera.
