Batteries

Everything is done with the inverter and solar now on to the batteries, I have 2 1 year old group 27 12v about 90ah each. should I just buy another since they are new or should I up grade to GC batteries or something else? I would like to keep the weight down

    With two perfectly good batteries I would connect one even two more as needed.
    With proper care they should serve you well another 5+ years.

    I would go with 2 GC's.

    That would up the ah from 180ah to 230ah with just 14 lbs more weight.

    of your biggest concern is weight just keep what you have GCs or other good batteries will weigh more
