the ones we got are 6500 watt but no inverter - that inverter adds a lot to the price but is the way to go for a home backup - MUCH cleaner power
they wanted 4800 for those - without the inverter i think we paid 2800 - we rationalized it by saying refrigerators and lights don’t care if power is clean - which is what was needed here
How much power do you actually get out of it?
