New Firman WO1781 generator inverter 1700/2100 watts. I have a parallel kit too. 4200 watts.

I have 2 new Firman 2100/1700 and a parallel for them. Firm $445 for each firm. Additional $55 firm, if you want the parallel kit also. They’re very quiet inverters. I have 3 hours of break in time on each one. Nobody does the break in properly on these but I did. So they are better than new if somebody buys them and doesn’t break them in properly. The way I did the break in: First you add some oil conditioner into the crankcase. Next fill up your portable generator with the appropriate amount of oil. Remove the spark plug. Using a funnel, pour just a little bit of the oil conditioner down into the spark plug chamber.This helps ensure that there is some lubrication in the cylinder before the first time you yank the cord to start the generator up. After the conditioner is in, pull on the starter cord slowly about 10 times.This allows the piston to move up and down in that newly lubricated cylinder. Replace the spark plug. Start it. For the first hour let it run at the lowest speed. It’s extremely important to let it run for this first hour on no load whatsoever. Then drain the oil.This helps get rid of the majority of those metal flakes and fragments. Start it up again and let it run for another hour at no load. After the second hour, power down and change the oil one more time. Once again, remember to add some oil conditioner. Start it up for hour number three. This time, you should add a bit of load, around 500W is recommended. After this third hour, your generator is officially broken in and you can start using it normally.
