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 48V 200Ah battery has a capacity of 9.6 kWh. This is calculated by multiplying the voltage by the amp-hour rating: 48V x 200Ah = 9,600Wh, or 9.6 kWh. To calculate the appropriate inverter size for a 48V battery system, you need to determine the total wattage of the devices you plan to power. [pdf]
