READ MOREInverters have a power rating in watts (W), which determines how much power they can supply, and the batteries have an amp-hour rating, which measures how much current (measured in Amps)
READ MOREThe sum will tell you which inverter size you need. Don''t forget that some appliances take more than their rated power at start-up. The inverter''s surge rating should cover these temporary increases. Example: A room has two 60 watt light bulbs and a 300 watt desktop computer. The inverter size is 60 x 2 + 300 = 420 watts; Daily energy use

READ MORELithium Sizing. 10kWh x 1.2 (for 80% depth of discharge) x 1.05 (inefficiency factor) = 12.6 kWh. Battery capacity is specified either in kilowatt hours, or amp hours. For example, 24 kWh = 500 amp hours at 48 volts → 500 Ah x 48V = 24 kWh. It''s usually a good idea to round up, to help cover inverter inefficiencies, voltage drop and other
READ MOREYour battery bank must be sized based on the maximum expected current draw, and depends on the battery type. The maximum charge/discharge rate for various deep-cycle battery types is: Traditional lead-acid batteries: 20-25% of amp-hour capacity. Gel cell batteries: 30-35% of amp-hour capacity.
