Victron Smart Battery Protect 12/24V-100A and Cyrix-ct 12/24V-120A

Hi there, I want to protect a 12v battery from being drained too far by a "dumb" small inverter with a low load on it. Apparently it's forbidden to have the inverter on the load side of the battery protect due to inverter inrush currents damaging it. The inverter has no remote control so the purpose was to cut the current if the battery gets too low.

Can I use the Cyrix-ct as a relay to cut the battery off using the battery protect as the control or are there any other solutions that can be implemented cost effectively?

The inverter will draw 1000w max continuous, and is not powering any loads like motors that require a large boost amperage.


Please assist?

Explanation that it's the inverter caps that cause a spark due to them charging immediately from the battery. SO one way is to pre-charge the inverter with a light or something in the circuit in parallel or use a relay. But if you use a relay you have to hack the inverter switch :-(
