I’m in the US and have two Multiplus 24/3000 in a split phase setup with a Venus GX for our house. I use this for load shifting typically running off battery from 3pm-midnight daily. I’m using node-red to make decisions about enabling/disabling grid feed in (no ESS since we can’t feed in to the grid in the US from Victron).
When we have power draw >1500W I switch back to the grid until the power draw is lower (usually either microwave or electric kettle). If the battery is less than about 20% the 50 amp breaker in front of the multiplus will trip when the Multiplus switches back to grid.
I’m thinking about using a Node-Red flow to enable power assist, limiting the grid feed in, then disabling power assist once it’s back on grid if these conditions come up. Alternatively I could disable AC output, enable grid AC input, then reenable AC output however this would obviously be much more disruptive and I’d like to avoid it.
I’m already using a 50 amp type C breaker, a type B breaker tripped more frequently.
I’ve found some older posts regarding tripping breakers and don’t see any real solutions, hoping somebody may have some useful input. The wiring does not seem to be an issue. Has anybody else dealt with this or have any suggestions to minimize the problem?
