I'm looking to buy this charge controller. My BMS might randomly disconnect the battery during charging. Will this damage the controller?
I've seen a few guesses to this question here, but I was hoping that some official Victron person could weigh in on this.
It shouldn't but it can.
It's a mixed bag. And depends on the circumstances.
In a system, if it is producing full tilt and providing loads and the battery is fully charged. Then suddenly load drops off battery disconnects and there is no where for the volt amps to go. It can.
Usually when the battery disconnects you see a spike in voltage on the terminals. This can damage components and shorten lifespan.
I have also seen many a time where the battery does disconnect and it hasn't to date stopped working.
The newer models are more resilient and the firmware has improved alot but obviously repeated disconnects under heavy production is not great for longevity.
It has been weighed in on a few times with Victron staff and mppts. One example below. Please note it is not your model but the principle applies.
