Step 1. Determine Current DrawStep 2. Determine C-RateStep 3. Determine The Amount of BatteriesTo maximize the lifespan of our batteries, we need to consider the C-rate of the battery. Remember from step 1 that a 1,000W inverter on a 12V battery will draw 83A? Lead-acid According to the C-rate (step 2) of a single 12V 100Ah lead-acid battery, we can only draw 20A. To maximize the lead-acid battery life, we need four 12V 100Ah batteries. This...See more on cleversolarpower
