How to calculate inverter size?

Using the Inverter Size Calculator is quick and easy. You’ll need three inputs: Total Wattage (W): This is the total power consumption of all the appliances or devices you plan to run through the inverter. Safety Factor: A multiplier to ensure some buffer above your actual power requirement. Typically ranges from 1.1 to 1.5.

Does your solar inverter size match your battery bank voltage?

Your inverter’s Size must match your battery bank voltage. Mismatched voltages can cause failure or inefficient charging. Some inverters have built-in chargers with a max current limit. If your solar array can deliver 50A, but your inverter charger only accepts 30A, that limits charging efficiency—an argument for matching proper Size components.
