My Grandfather just purchased a cheap solar panel kit for his ranch that could not muster enough power to run his mini fridge.
He has two 6 volt batteries running positive to negative and would like to add more batteries. Probably 12volt. How would he go about hooking up the other batteries and what kind of wire or coil should he use.
Also, I saw on youtube a guy recommending a lead-acid battery from walmart for under . I was just going to go to ecology and just pick up some used batteries but I may be wrong.
Any help for a first timer might help me and my gramps out will be appreciated.
Thank you
If your desired voltage is 12V then you will hook up your 6V in series, and your 12V in parallel.
Depending on what your amp draw of the fridge is, will determine the gauge wire you need from the battreies to the fridge.
The used batteries are probably there for a reason, they don’t hold a charge, you are better off using new batteries or if you know, or know someone who knows how to "load test" a battery you may get a good deal with used ones, but don’t get them without a test being done.
