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]

A 48V system is generally considered more efficient than a 24V system, especially in applications that require higher power. The higher the voltage, the lower the losses in the wire, which means that power is delivered more efficiently to the target devices. [pdf]
[FAQS about Is 48V or 24V better ]
If you hook a 36V battery pack to a 48V controller, it likely won't function at all because of the 42V LVC of the 48V controller. It might twitch when you move the throttle, but that's probably all it will do since the load would probably cause the voltage to sag below LVC immediately. [pdf]
Before we go any further, we highly recommend that you choose a pure sine wave inverter. This type of inverter delivers high-quality electricity, similar to your utility company.. .
We have summarized the appliances that inverters from 300W to 3000W can run depending on their rated maximum power. Note to our readers: Use the above formulato determine. Result: To power the above appliances simultaneously, you’ll need a minimum inverter size of 600 watts. Remember, the x1.4 adds extra security if any of your appliances are inductive loads.
