Frequently Asked Questions
What inverter size do I need for my solar system?
The inverter must cover the total running wattage of everything that may run at once. Sum nameplate wattages of devices that operate simultaneously and add 20 to 25 percent headroom. For motor loads (fridge, pumps), confirm surge capacity reaches 3 to 7 times the running watts.
Pure sine wave vs modified sine wave: which should I pick?
Pure sine wave matches grid power and runs anything safely. Modified sine wave is cheaper but incompatible with AC motors, audio gear, smart battery chargers, and many sensitive appliances. For household use, always choose pure sine wave.
Can the inverter handle motor and compressor startup current?
Good inverters have a surge rating of 2 to 3 times their continuous rating for a few seconds. Make sure the surge spec exceeds the startup current of the largest motor in your system; otherwise the inverter trips on every restart and the load never reaches steady state.
