I have a Renogy DCDC 12V 60A device put between my two separate lithium banks (680Wh + 400Wh). It works fine, but the other day, the source bank was cut off due to low voltage (each lithium battery has its own BMS by factory). This bank is charged by solar panels, so at night, it can be used up completely. Everything came back fine, once the panels started to charge again.
Is there a way to disconnect the DCDC device from the source battery bank at certain voltage? How is this setup?
The installation manual of the DCDC does not address this scenario, because it assumes that the charge will come when the ignition wire is active. My setup has this wire always connected and my alternator is not involved in this configuration. I am just supplying the house battery bank from the solar battery bank. Again, it works very well, but I would not mind to have some kind of protection on the solar battery bank, so it will not go ' empty '.
