What is the Best Battery for an Off-grid Solar Power System:
Choosing the right batteries for your off-grid solar system is highly important because different types of deep cycle batteries have varying levels of energy efficiency, cost effectiveness, and storage capabilities. There are some things you need to consider when choosing the right solar battery, such as battery lifespan, ease of installation, cost, and storage space. Below, we can help guide you to figure out which battery will be the best battery for your solar panel system. |

Types of Batteries:
Deep cycle batteries are the recommended batteries to use in solar installations. There are a range of different deep cycle batteries, including lead acid, sealed lea, AGM Batteries, Gel Batteries, and Lithium LiFePO4 batteries. Lead acid batteries:
AGM Batteries:
Gel Batteries:
Lithium LiFePO4 batteries:

HOW LONG DOES YOUR SOLAR KIT TAKE TO CHARGE A 12V 100AH BATTERY? Sunlight, temperature, and battery will influence specific charging times. To get a general idea, you’ll need to calculate amps delivered from your solar panels (total wattage/voltage of your battery). Then you’ll divide the amp hours of your battery by amps delivered. For example, if you have a 100ah 12v battery with three 100 watt solar panels, your system would deliver 25 amps. By dividing 100Ah by 25 amps, you’ll learn it will take four hours for a 300 watt solar panel system to charge a 12v 100ah battery. |

Can you wire different battery types and sizes together?
We recommend wiring batteries of the same type and amp hour rating in your solar installation. For example, if you go with AGM batteries, all the batteries in your battery bank should be AGM batteries. This will limit any efficiency loss due to having different batteries. |
