FAQs

How should I size off grid solar batteries for my loads?

Start with daily kWh usage × days of autonomy ÷ allowed depth of discharge, then confirm your PV can fully recharge that battery in typical sun hours; more batteries without enough solar won’t fix energy shortfalls.

Which battery chemistry is better for off grid solar batteries: LiFePO4 or lead-acid?

For most modern systems, LiFePO4 offers deeper usable capacity, longer cycle life, and simpler maintenance; verify your inverter/charger settings and any needed equipment changes when upgrading from FLA.

How can I extend the life of an off grid solar battery bank?

Keep lithium SOC roughly in a mid-range (many users target ~20–80%), set correct charge voltages, and manage heat with adequate cooling/ventilation—high temperatures shorten battery life.
