Review on ECO WORTHY Charger Inverter Controller Off Grid by George Utley

Bought yesterday. Even before arriving I know I will be back.1. Read the manual. 0, NONE, NADA, in the instructions for connection to the grid/generator input. All images suspiciously hide inputs. Finally with help, saw a picture of 110 ac. Ok BUT there are no instructions on how to hook up/connect. Why hide this picture? Maybe because a double cable is needed? I can make one.2. My generator is 3500 watts. When viewed, the maximum input power is 2000 watts. It was in 1 set.3. Read the wording CAREFULLY. This item will not charge batteries when using Grid.4. Because in the picture there was also a generator that I bought as a grid. The manual doesn't mention any generator at all.5. I've repeatedly asked if lead-acid batteries work. No Answer. Bottom line: horrible management, mean wording etc. Would have canceled the order but shipped. Will be returned unopened. Another: an eco-friendly website that sells the same inverter with an additional 30 amps for less money.
