Re: Off grid backyard trailer solar
Essentially correct. The power the generator has to supply will be somewhat higher than the charging wattage though. For example, IIRC, my Iota chargers have a relatively low power factor, so 720w ch…1 · -
Re: Off grid backyard trailer solar
Charging current is generally DC bank capacity / rate. For example a C/10 rate on a 225ah bank would be 22.5adc. A C/5 rate would be 45a. To put 45a into a 48v bank (ignoring losses and charger pf) w…1 · -
Re: Off grid backyard trailer solar
OP did mention lithium, which could work well, but suggested "cost not worth the investment for this trailer experiment".1 · -
Re: Off grid backyard trailer solar
Using an AGM with a somewhat faster charge rate like C/5 could work well if you planned to routinely charge with generator in the morning, and use solar to carry loads and finish charging to the exte…1 · -
Re: Off grid backyard trailer solar
Some AGM batteries are designed to charge faster (assuming, of course, there is current available to support the higher charge rate). A car battery, for example, is designed to deliver high current r…1 ·
