How do I charge with CCGX off and batteries flat?

Hypothetical as it hasn’t happened yet, BUT IT WILL so I am being prepared.


i have a Multiplus 24/3000 CC GX mppts battery monitor and custom lithium pack.


in the past when the battery goes flat I just pop outside, fire up the genie and the charger automatically starts .


however, with the CC GX controlling things, and it bring off, whats going to happen?


do I manually flip the Multiplus to charger mode? Will it respond to this And charge? Do I need to disconnect from the CC GX ?

is there a magically sequence to get it going to charge?


just trying to prepare for the inevitable.


thanks in advance

The inverter doesn't need a GX to black start, it is needed to avoid deadlocks, which is something else. The multi has a full config of its own. Properly configured it should recover and start working again when restart thresholds are met and there is a power source (genset) on AC1.

Ideally though, you want to be setting cut off values so you don't run a battery completely flat, that isn't great for any battery and avoids issues.

Thanks for the reply.


So in effect when it detects the generator it will restart the multi

yes I have the bus set so it’s not dead flat, but in effect I will still loose the batteries and be blacked out.
