How We Picked And Tested
To find the best solar car battery charger, you need to consider the factors that you should decide on when comparing different solar chargers. With a solid knowledge on the things to check, you’ll be able to pick the right one that can cater to your needs. In the following, let’s begin with the considerations for choosing a car battery charger.
There is nothing as frustrating as not getting what you need from a solar charger. That is why you need to check for a device’s efficiency rating when comparing your choices. For example, make sure that it can work even when not placed under direct sunlight to charge the battery. It must also work even on cloudy days and in places with a low lighting condition.
When choosing a solar car charger, you must also check the size and weight of the product that you’re buying. As you know it, the solar charger should be portable. It will allow you to bring the charger anywhere, especially in your outdoor adventures. With it, you can keep your car’s battery charged. Nevertheless, you must find a charger that can fit comfortably in your car.
A reverse charge blocking diodes
They will allow your charger to keep the energy it collected from the sunlight. They can prevent the power from leaking out when the charger is not in use. But then, this feature is available in many chargers on the market. In this case, you will not have a hard time in finding one that has it.
Many of these devices have a power that range at most 18V. The lower it is, the lower the power is. But then, even at a voltage of 18, it will not overcharge the battery. However, a higher voltage ensures that your battery will be charged faster. In all cases, you must find a solar battery charger that has overcharge protection to prevent the damage to your battery.
Cables and connectors
When shopping around for a charger, you might want to get one that comes with at least two connectors. They should give you different connection options that you need. It will also help if you selected one that has a long power cord for more options.
Frequently Asked Questions
Can I use a car solar battery charger with other batteries and devices?
Yes, you can use an auto solar battery charger with other batteries and devices, provided these items meet the charger’s technical specifications. For example, a 12V solar battery charger for lead-acid batteries might not work with a lithium-iron-phosphate (LiFePO4) unit because of different battery chemistry.
Moreover, the solar power battery charger for car must also deliver ten to thirty percent of the battery’s ampere-hours rating. For example, a 10- to 30-amp solar battery charger with overcharge protection is sufficient for a 100Ah battery.
It is also worth noting that most solar car chargers cannot revive dead batteries. These devices do not charge batteries as fast as conventional ones – the reason many vehicle owners call them solar powered trickle chargers.
Do solar battery chargers work better than normal chargers?
No, a solar power charger for car battery is not as powerful as traditional ones as they extend charging times. For example, a 20-amp conventional charger needs two to four hours to fill a car battery, while a four-amp vehicle solar battery charger needs 12 o 24 hours to charge the same unit.
Automotive solar battery chargers also deliver minimal current to car batteries, making them ineffective in reviving fully discharged power cells. These devices are more suitable as a car solar trickle charger, topping off and maintaining a battery’s charge.
The only advantage of solar powered car battery chargers over conventional ones is the electricity cost savings from not using the power grid. That aside, solar energy is also cleaner and friendlier to the environment.
How long does a solar car battery charger last?
Solar automotive battery chargers can last as long as their weakest component, and that would be anywhere between 15 and 30 years.
To gauge the expected lifespan of a vehicle solar battery charger, you’ll need to break down its components. Overall, the device includes:
- A solar panel.
- A solar charge controller.
- A single-ended primary-inductor converter (SEPIC).
- Other vital parts.
Solar panels have an average lifespan of 25 years, although it is possible to see the latest products have better longevity. It is also worth noting that solar panels continue collecting and converting energy beyond their lifespan, albeit at a reduced capacity.
Solar chargers with charge controller technologies might last fifteen years, regardless of their typing. The same applies to solar car chargers with regulator units. On the other hand, DC/DC converters (i.e., SEPIC technologies) can continue operating for up to three decades.
Is a 100-watt solar panel enough to charge a car battery?
Yes, a 100w solar panel is enough to charge a car battery. Most automotive batteries have a 40- to 65-Ah rating. We can calculate the panel’s amperage output by dividing 100 watts by 18 volts (the maximum output under optimal conditions) to get 5.5 amp-hours.
Suppose you have a 50Ah car battery with an 80% charge (40Ah). In that case, you will only need to top up ten amps and recharge the battery for about two hours (10Ah ÷ 5.5Ah = 1.81 hours).
What are the most trusted solar car battery charger brands?
Some of the most trusted brands for a solar car battery are Sunway, ECO-WORTHY, and SUNER POWER, among the rest featured in the reviews. They are reputable and concerned about the quality of their offers. You can check them out to compare your options thoroughly.
What is the top-tier 12V solar battery charger?
There are many sun-powered chargers. If you were asking about the qualities that make a great one, we could start with versatility. Such devices must be suitable for applications, including RVs, trucks, Powersports, and tractors, to name some. The solar battery chargers are also durable for long periods and made of heavy-duty components. Sun-powered chargers must also be easy to operate and requires no maintenance. Car chargers also need not be costly. There must be a balance between the price and the quality, nonetheless.
How do you use a solar car battery charger?
At the very least, the solar car chargers are with a solar panel. They are like other solar products on the market. You must position it on top of your dashboard, near the window, or in a position where it can absorb sunlight. Some models can also connect directly to the battery. Others feed the power to the battery using a power socket or a cigarette lighter.
Do solar panel trickle chargers work?
Yes, the car battery trickle charger will work. But then, make sure that you are using it for intended applications. Also, remember that these chargers are not available in different amperage ratings. In this case, one can only provide a small current amount to the battery.
How to care & clean?
There is not much to do once the installation process of the car battery trickle charger is complete. You don’t need to maintain these solar devices, one of their primary advantages. You can just plug-and-play many of these, too. There is no need to care or clean, but do not mishandle it because some are made of plastic.
Where to buy?
It is easy to find these devices in many places, including eBay, Amazon, and manufacturer websites. Walmart, Lowes, home depot and other locations also sell them. Before buying one, compare for the features that you want your car battery charger to have.
Hoping you’re able to pick the best solar car battery charger for your needs and requirements. Don’t just add anything to the cart without understanding what you’re buying. It is a great idea to start with the comparison process using the buying guide earlier. Check out the top suggestions on the market. The solar battery chargers are highly-rated by consumers for their excellent features and performance. Compare their pros and cons to get to know them better. Later decide based on the features that you want your car battery trickle charger to have. Refer to the considerations to think about so that you will have a better idea of what you’re buying.
