Lithium battery for solar systems

Description

Batteries store energy so you can use it at night or when the power goes out. For solar systems we work with lithium iron phosphate (LiFePO4) batteries, a stable chemistry that generally handles many more charge and discharge cycles than lead-acid batteries, doesn't need topping up with water and takes up less space. Each battery has its own battery management system, or BMS, which protects it from overcharging, deep discharge and high temperatures.

The key question is how many hours of backup you need and for which appliances. Capacity is measured in kilowatt-hours, and keeping lights, fans, the refrigerator and the internet running is very different from running an air conditioner all night. With your list of appliances, we recommend a realistic capacity, and you can start with a small bank and expand it later with compatible batteries.

We install them in a cool, ventilated spot out of direct sun, with their own breaker and correctly sized wiring. They must be compatible with your inverter so the two communicate properly; if you already have an inverter, we check compatibility before quoting.
