So first thing I'll discuss with my electrician is if we can convert to a single phase and have no tripping issues. If that's a go, like mentioned I would ask for a quote on 2 inverters in parallel and a nicely sized array and battery bank. Otherwise if 3 phase needs to be kept, I'd maybe have a solar backup on 1 or 2 of the 3 phases instead of using a 3 phase inverter. Last option would be to stick with a 3 phase inverter?

Thank you for this, the new house electrical set up and solar installation is potentially the same company hence this can be brought up.

Hey 87 Yes I'm leaning towards reordering maybe 2 phases for more essential items instead of only 1 of the 3, do you forsee this being a problem? Over 2 and not 1 is just for better load balancing the 3 phase system or would unbalanced loads (as per Tariqs question) not be an issue?

Hey Leshen Thank you for that, we generally use abit of underfloor (underactive thyroid necessitates this) as well as a pool heat pump (not used right now obv) and on a single phase we've experienced a lot of tripping of the DB. While we don't plan for any 3 phase appliances, it seems we rather have a 3 phase system. I see the pylontech h2 is 48v for the sofar and the freedomwon (for the victron) is 52v to suit 48v inverters. Would 2 8kw Sunsynks in parallel be a better option on two of the more used 3 phases then a sofar 15kw?

Howzit guys I need assistance and advice as I've searched as well as talked to multiple suppliers. I have an option of 2 different installations. The one is using a 15kw 3 phase inverter sofar solar or 3 X single phase 5kw victron (dc coupled ess storage) The solar input is around a 12.6kw array and for the 3phase inverter it will be pylontech power cube h2 batteries and for the victron it would be Freedom Won. From what I've researched the 3 phase will only supply max 5kw per phase. The victron I was told it can dynamically supply as required and as available from solar and battery (acc to setup) (but haven't been able to find info conclusively either way), is this correct? So my main aim is being able to cut down electricity bill (and this will involve playing around with what % of battery I'd like to use during the day once charged (for example 50%)) and more importantly having backup during load shedding (with some heating appliances in peak winter) What I've found is the freedomwon is more expensive but has a 1C rating while the pylontech is 0.5C. My question is which of the 2 system would see a better roi and month to month saving if the battery system /solar input is comparable. Has anyone installed either a 3 phase or 3 X single phase in parallel for a 3 phase house?
