We offer Home Ups & Inverter.
Features
1) Completely controlled by CPU, and it is unique throughout the world, when you increase the stability of the inverter, it reduces its costs:
2) Super wide input voltage:90v-280v, and it has a converter switch, when it was 90V-280V, it is used for INVERTER, but when it was 175V-265V, it is used for UPS, so it is attractive and convenient, what is the most important is that its price is competitive, I think you will like it very much.
3) Protections against output short-circuit; against overload, and when you throw off its load, it will turn on the unit automatically.
4) Functions that when the AC comes in, it will start the unit automatically: and when its overload, it will also close the unit automatically, when you cancel the load, then it will return to work automatically.
