Hi there,
I have a new 3ph system, 3 MP II with cerbo gx, 24kwh pooled BYD LVS batteries (Li), with victron meters on 3ph and solar (1ph) heaviest load is heat pump.
I have smart tariff - cheap 6 hours overnight, 5x expensive during peak
I have 3.6 kwh solar (which will be increased)
Installer set up system with Battery life, with 95% charge limit. Regulation across phases is on.
Reading the forums and watching victron youtube, it's not clear whether really need battery life? or indeed whether
I charge batteries off peak and discharge to power loads. Then if there is excess solar (not much in winter), it tops up batteries a bit.
In this scenario, should battery life really be used / does it actually help?
In contrast, in summer I intend to charge overnight (but to a lower SOC) and then top up more with solar as there is more of an excess.
In this scenario, would battery life be useful (would typically expect to capture 10kwh from solar) and charge battery off-peak to between 40% (or higher when no solar forecast next day)
Would very much welcome the communities help on this!
