Does anyone know if it is possible to set a Victron inverter such that it only ever charges from solar power?
At the moment, I can “semi” do it by setting scheduled charging, but if I want to use a high “stop on SoC” (like 90%) it would also charge from the grid. I’d like to start using the battery after it is full enough, so not sure if I can hack together such a solution with the settings at my disposal.
The reason I’m asking is due to the proposed CoCT regulations, limiting the amount of current you may pull from the grid to charge your batteries. That seems to be the toughest one to get around without limiting inverter power.
If I am able to enable an “only charge from solar” setting, behind a “password”, then I can manually limit the inverter power and charge from the grid if ever I feel like the batteries need a full charge after days of bad weather. All other times, I would be able to be ensure that there’s no chance I could ever charge from the grid and exceed their limit.
While I do feel the charging limit is a silly rule to implement just on those with generating capacity, because the real demand would come from those with only backup system, I guess one needs to operate within the confines given to you.
