Trying to avoid installing a generator transfer switch.
In the event of low battery (under 20%) AND grid failure can I use a small generator to charge the batteries with an external stand alone "Blue Smart Charger" while still utilizing the normal capability of the Multiplus II inverter? When I say normal I mean this is a small cabin with a typical full load of about 350 watts. 900W microwave on occasion.
What if the power comes back on while charging? Should the main breaker be turned off before attempting this?
What about solar charging at the same time? Is that going to be ok?
Grid connected ESS with the following equipment.
