To recharge your battery from time to time you would need the right size solar panel to do the job! Read the below article to find out the suitable solar panel size for your battery bank .
Note!The battery size will be based on running your inverter at its full capacity Assumptions 1. Modified sine wave inverter efficiency: 85% 2. Pure sine wave inverter efficiency:90% 3. Lithium Battery:100% Depth of discharge limit 4. lead-acid. .
To calculate the battery capacity for your inverter use this formula Inverter capacity (W)*Runtime (hrs)/solar system voltage = Battery Size*1.15 Multiply the result by 2 for lead-acid type. .
You would need around 24v150Ah Lithium or 24v 300Ah Lead-acid Batteryto run a 3000-watt inverter for 1 hour at its full capacity .
Here's a battery size chart for any size inverter with 1 hour of load runtime Note! The input voltage of the inverter should match the battery voltage. (For example 12v battery for 12v. A 100Ah LiFePO4 battery can safely power a 1200W inverter, while lead-acid should cap at 600W. Gel and AGM batteries have intermediate tolerances. Mismatching chemistry and inverter size accelerates degradation and voids warranties. [pdf]
