We use the Gen set for work and farming. The battery charge option is a great bonus, however I have not had a chance to use it yet. It was put through its paces for about three weeks, 10 hours a day without fail. the remote couldn't work better. Weather ranged between plus 10 dec C to minus 5 and the unit started without fail each day.
My camp is off grid, in the winter time it is dark from 5 pm to about 7am so we do not get as much sun, for the solar system. With the remote control it. Is easy to turn the generator on when we need it.
