Depending on the size and type of inverter, using a 12v car charger could save a fair bit of power. Inverters can be pretty inefficient powering loads that are small relative to inverter capacity. So…1 · -
Re: 3 months no grid power, you all saved me
Good to hear it's working out. At 12.7v min overnight, your batteries are staying nearly full, and should last some time. Still, the batteries are likely to go before panels or electronics. When they…1 · -
Re: Newbie ready to go off grid
Flooded lead acid batteries will take a charge of ~15-20% of bank capacity during the bulk stage (to ~85% full), then take another 3-4 hours with diminishing current to fully charge. Some other types…1 · -

Re: Crown CR350
The EQ instructions are really more applicable to a grid charging regime. Off-grid, there may not be time for what's effectively a 6-8hr absorb cycle. For off-grid, we generally do a shorter EQ at a …1 ·
