So, a 200Ah 12V lead acid battery with 50% DOD could power a 1kW inverter with 95% efficiency at maximum load for 1 Hour and 8 Minutes. Now using the knowledge that you learned in this article, you will be able to use the following calculator easily. You will need to input the total battery bank capacity in Ah and the total voltage V.
The faster you discharge a lead acid battery the less energy you get (C-rating) Recommended discharge rate (C-rating) for lead acid batteries is between 0.2C (5h) to 0.05C (20h). Look at the manufacturer’s specs sheet to be sure. Formula to calculate the c-rating: C-rating (hour) = 1 ÷ C
Formula: Lead acid Battery life = (Battery capacity Wh × (85%) × inverter efficiency (90%), if running AC load) ÷ (Output load in watts). Let’s suppose, why non of the above methods are 100% accurate? I won't go in-depth about the discharging mechanism of a lead-acid battery.
Battery Running Time = ( Battery Power Capacity (Wh) / Inverter Power (W) ) x Inverter Efficiency % Battery Running Time = ( 1200 Wh / 1000 W ) x 95% Battery Running Time = 1.14 Hours or 1 Hour and 8 Minutes So, a 200Ah 12V lead acid battery with 50% DOD could power a 1kW inverter with 95% efficiency at maximum load for 1 Hour and 8 Minutes.
Battery Power Capacity = 1200 Wh After that, we will use this number to find the duration the battery could run the inverter. Let’s say my inverter is 1kW = 1000 W with an efficiency of 95%. The equation is: Battery Running Time = ( Battery Power Capacity (Wh) / Inverter Power (W) ) x Inverter Efficiency %
For example, if your 200Ah battery is lead acid, then you must not exceed the 100Ah limit (50%). You should also determine two important parameters from your inverter. It is the maximum power for your inverter and the inverter efficiency. The power is fundamental, and you probably know how much power your inverter is (1kW, 3kW, 5kW…).
