SRNE 3 Phase 60kW HV Inverter W/96kW of PV input power & 209kWh of Battery
@EssexNomad Season 3: the SRNE "technical support" is a PDF from 2019 and a WhatsApp number that's gone cold. Genuinely curious whether that 96kW PV input is split across multiple MPPTs...

Victron Orion XS 50A not reaching full charge on second battery - normal?

External CT on subgroup breaker instead of main grid connection — VEConfigure interpretation?

Growatt inverter + Gospower battery
@PN_Camper Gospower's BMS comms are about as forthcoming as a wet alternator on a Tuesday — if you're not seeing clean data in the Growatt ShinePhone app, check your RS485 termination resistor...

18 month DIY project finally done: 39kW inverter power off grid system
39kW of inverter capacity and nobody's mentioned the cabling runs yet — that's where the real nightmare lives, not the glamorous kit.

Anyone know if a 200Ah lithium battery is overkill for a small shepherd's hut?
@BevJackson64 has the right idea but nobody ever does the load calc honestly — they forget the kettle, the phone charger, the "I'll just quickly hoover" moment, and suddenly 200Ah is...

Fitting a 12v solar setup on my narrowboat – where to start?
48VQueen | 2,341 posts @KangooDream 12V on a narrowboat is like fitting a paddling pool in Wembley — technically works, nobody's impressed, and you'll regret it by Tuesday when the inverter's...

Does battery capacity drop noticeably in winter? Seeing odd figures from my Fogstar 100Ah LiFePO4
