How many watts of solar panels are needed for a 900ah battery
Result: You need about 120 watt solar panel to fully charge a 12v 50ah lithium (LiFePO4) battery from 100% depth of discharge in 6 peak sun hours. Read the below post to find out how fast you can charge your battery. For example, a 200 Ah battery can provide up to 2,400 watt-hours (200 Ah x 12V) of energy. Also the charge controller type and desired charge time in peak sun hours into our calculator to get. . If you are using an DC to AC power inverter, meaning your device is rated in AC amps and 110 V, you will need to convert that number into DC watts before entering it in the field. Then you will need to add about 10% due to the inefficiency of the power inverter. Formula: Charging Time (h) ≈ (Battery Ah × V × (Target SOC / 100)) ÷ (Panel W × (Eff% / 100)).
