I love mine. I have more then I need for my normal use but the extra capacity is nice. From the time the snow melts off the roof, until fall I never need to plug in. My unit does have a built in generator which gets used to run the microwave, toaster oven or AC. Occasionally when traveling in the winter I do use the generator to help with charging.
I have 450 ah worth of batteries and just over 500 watts of flat mounted panels. I have a HF 1000 inverter/charger. This takes care of the lights, fans, TV, computer, CPAP over night, furnace, misc charging.
Originally I only had half the batteries and solar, but I work on Wildland fires and a couple of days with no sun due to inversion meant I was not getting a good charge. Now that I have doubled my system the last 2 years has been no problem. I have about $2000 invested in my system now.
In my next unit, which will have much more that needs power I will be looking at close to 1000 watts of solar, a 3000 watt hybrid inverter and larger battery bank.
