Hi, I have an off grid installation with a DC Coupling via Victron Smart Solar, Victron Multiplus and OPZS batteries. I want expand it via AC Coupling, but until April there aren't Fronius Primo on market, for this reason I bought a Solax inverter.
Multiplus communicates to Solax increasing frequency, but I'm afraid this increase may damage the appliances or may lead to a malfunction of these.
I have a Smart Meter Chint DDSU666-D 80A 1Ph, it's an export limiting meter.
I want install it between the AC Out Multiplus and the house loads, so that it regulates the Solax according to the loads and no energy is sent to the Multiplus.
There are any problem with this configuration?
Maybe I could set the Multiplus to very low frequencies such as 50.01 instead of 50.20 to start the Solax output reduction, 50.03 instead of 52.70 to minimize and 50.05 instead of 53Hz to stop the Solax?
If I don't configure the Solax it will be regulated by the Smart Meter regardless of the frequency sent by the Multiplus, right?
What will happen when the Multiplus detects that the Solax has not stopped?
With my DC Coupling system, now I can charge overnight consume and batteries stay on float almost all day.
I attach a simple diagram.
Thanks.
