Grid-off systems are independent from the utility grid, avoiding the possibility of losing power when the grid goes down. Electricity from grid-off systems is used on site, such as an RV or cabin. Power that is generated can be stored in batteries and used on no wind days. A generator may also be used for back-up.
Features:
 1. Controlled by CPU, pure sine wave output, it can drive different kinds of household appliances and industrial appliances. Such as tube lights, refrigerators, air-conditioners, dynamoelectric tools and so on.
 2. Output slow-starting function, even though you open the unit with loads , it won’t damage the inverter
 3. High transfer efficiency, it is up to 85% when it drives tube lights, which save the input of the solar energy and wind energy.
4. With complete protective functions, protections against output overload, short-circuit, input with high voltage and low voltages, etc.
5. With most advanced technologies, it has been up to the best cost performance.
