Two Inverters on one Battery Bank
Let''s say you have a 2000W inverter and want to add another 1000W inverter. 2000W + 1000W = 3000W. 3000W / 12V = 250A. 250A x 1C = 250Ah. You need a 12V, 250Ah battery to support a 3000W inverter power. If you have a lead acid battery, multiply by 5 (C/5 or 0.2C): 250A x 5 = 1250Ah. Wiring and Safety
