I have an EasySolar 48/5000 which is given with a max 50A AC input limit. This is fine for my normal use including my heat pump.
Except that my heat pump is having random fault some of which are causing excess current at startup (I suspect compressor sometimes lock) and draws up to 90A.
No alarm on Victron-side, no breaker trips so I suspect either the heat pump “handles” it faster but I’m not sure. All know is that by looking at VRM it lasts within the time range of 1 minute.
I’m obviously concerned by this situation and whilst I’ll look into getting the heat pump fixed I’d like to know what are the safety mechanism and risks on the Victron equipment
How is the Multi setup? All loads on AC OUT or grid paralleled?
Not paralleled but split between ACout1 (backup) and ACout2 (Heat pump).
To be safe, I suppose I could change my setup with an external meter
- Heat pump between external meter and ACin
- house on ACout1 backed up
I assume the set up no injection on grid would work as long as I change to external meter in the VE config!?
Hi Philippe.
Yes, was thinking same to have the heat pump in parallel and use a meter to control external feed-in. See this article for some insight of what to expect. This ‘slowness’ I personally think people overexagerate. Matter of seconds - have seen it myself - of course it takes time to ramp up.

This way you are not limited by inverters rating.
