How much gas does your genny use? And a charging question

you do what you gotta do. The solar is the key & are getting reasonable. I bought 2 100w panels & 30a controller for $319. Even in low light they will recharge the following day. On a rainy day they will produce about 5/6a. I only use my inv for tv/dvd so my consumption is low unless it warms some & I have to use my 2 fantastic fans. I use my onboard 4K onan for coffee maker & microwave. A good batt bank is also a key item. I have 2 gc2's @ 232a
