HOW MANY WATTS DO YOU NEED?

To determine the size of a backup/solar core system add the watts for items you may want to run at the same time. Use the total wattage, plus 10% to 20%, as your minimum power requirement. Note: The wattage given below are estimates. The actual wattage required for your appliances may differ from those listed. Check the nameplate on the appliance to determine the actual wattage required.

*Appliances and tools with induction motors (marked * in tables) may require from 3 to 7 times the listed wattage when starting. The start-up load of the appliance or tool determines whether an inverter has the capability to power it. e sure to check the specific wattage requirements and operating instructions for appliances / tools to be used.
