As we know, the off-grid Solar power inverter is the key equipment for the whole off-grid solar system to power home appliances by converting DC voltage to AC voltage. It depends on the efficiency and reliability of the whole system. 

How to choose a reliable inverter for your off-grid solar system?

There are modified sine wave off-grid inverter and pure sine wave off-grid inverter.

Off-grid modified sine wave inverter

  1. lightweight and cheap
  2. best for the simplest system to power bulbs and fan

Off-grid modified sine wave inverter is a good choice for the basic needs family to power light and fan. But for any more modern electronic loads like TV or something big load appliances, a modified sine wave inverter is not a good choice.

 

Off-grid pure sine wave inverter

  1. Perfect for all kinds of appliances, especially inductive load like an air conditioner, refrigerator.
  2. heavy-duty and reliable
  3. full protection against battery and load
  4. Generally more expensive 

Pure sine wave inverter works in almost all types of the off-grid solar power system. Generally, pure sine wave inverter is used in a large solar system over 1000W.
