I depend on Solar PV and a big battery for mains power, with a diesel generator for backup. I bought the generator new 6 months ago.
The generator is wired for automatic start when the State of Charge drops to 82%. Twice now it has failed to start due to a flat battery. The SLA battery is the size one would find in a compact car, and the drain on it appears to be about 10ma when the generator is not running.
I tried a small pv panel, but with no sun for several days the generator's battery was not up to starting this morning.
If I connect a small automatic charger, can it be left connected while the generator is running?
Alternatively, I suppose I could use the 12v output to activate a relay to automatically disconnect the charger.
Thanks
