Knowing the features of the best solar batteries enables you to choose the perfect one for your solar energy system. While evaluating the solar batteries, the essential criteria would be comparing battery power rating and capacity, its depth of discharge, warranty, and round-trip efficiency as well as brand.
Battery capacity simply shows how much electricity the solar battery can store. Solar batteries for residential use have been designed with stackability in mind, enabling us to use multiple batteries for our solar system and gain extra capacity. You may check the power rating to know the amount of electricity a battery can supply.
Depth of Discharge shows the amount of battery capacity one can use since using 100 percent of a battery’s charge will decrease the battery’s life. Search for the best solar batteries with higher DoD since you can get more out of your battery compared to the ones with low depth of discharge.
The percentage of the amount of energy that can be used, compared to the amount of energy it is required to store the energy is shown by a round-trip efficiency number. The higher the percentage the better the efficiency and you can get more value out of the battery.
Check out the warranty for battery life to know how many times you can recharge the battery and still get a decent amount of time out of the battery without it running out of power. The brand of battery is essential in this matter since different brands have different battery life warranty.
Keeping these details in mind, we have done some research and compared different products to find the best ones for you. Here is a list of top solar batteries available on the market gathered by Linquip:
