Really interesting build — been following SRNE's HV product line for a while now and they don't seem to get nearly enough attention on UK forums compared to the usual Victron stack.
A few things I'm curious about:
Battery chemistry? 209kWh is a serious bank. Wondering if that's LFP cells or something more exotic. Also keen to know the BMS setup — whether SRNE's native comms protocol is playing nicely with it or if there's a third-party BMS in the loop.
Grid-tie vs off-grid operation — is this running in island mode full time or does it have grid backup? At 60kW three-phase I'd imagine it's serving a fairly substantial load profile. Commercial premises or a larger homestead?
I run a much more modest Victron Multiplus-II setup on a narrowboat so I'm obviously not in the same league here, but I've been doing a lot of reading around larger SRNE installs because I'm helping a friend plan a 15kW system for a rural smallholding. The SRNE documentation in English is... patchy at best, which has been a sticking point.
96kW of PV input across how many strings? Interested in the array configuration — roof mounted, ground mount, tracking? The clipping losses at that input-to-inverter ratio must be worth thinking about depending on orientation.
What inverter firmware version are you running? There've been some reported quirks with reactive power control on earlier builds apparently.
Would be great to see some yield data once you've got a few weeks of monitoring logged — even rough Wh/day figures would be genuinely useful for the community here.
