Off Grid Inverters
Off-grid, or standalone, inverters convert DC power stored in batteries to AC power that can be used as needed. Select an inverter for your power system based on the maximum load you will be powering, the maximum surge required, AC output voltage required, input battery voltage. The size of an inverter is measured by its maximum continuous output in watts. This rating must be larger than the total wattage of all of the AC loads you plan to run at one time.
Wattage of most AC loads can be determined from a tag or label on the appliance, usually located near where the power cord enters, or from the owner’s manual. If the inverter is expected to run induction motors, like the onesfound in top loading washers, dryers, dishwashers and large power tools, it must be designed to surge, or deliver power many times its rating for short periods of time while these motors start.
