Re: Tech help needed on homemade solar system

For starters you say you have a 7 watt charge controller, and 30Watts of panel, this will not work.

you may have a 7Amp charge controller which is fine.

Questions?

where is the system located (zip code or state)?

your load is 732 amp hours and you do not have that much charge capacity or that much battery capacity.

if you have 4 peak sun hours ( deep south US ) you are generating about 7 amp hours of power a day. on a good day.

so if you are charging for 5 days you will get 35AH of charge back in your batteries, you need a lot more panel. This all assumes that your loads are what you think they are and that the inverter is 100% efficient which it is not.

Hope this helps
