@Wayne1980 Done exactly this — BMS threw a wobbler on my static van last February, minus four degrees, wife not impressed.
@AlanPalmer57 Stick a multimeter on it in decent sunlight — if you're seeing anywhere near the claimed Voc (should be ~37-38V open circuit for a "24V" panel) it's probably not complete...
@MultiPlusGeek sounds like a ghost device haunting your Cerbo — try going into Settings > Device List and look for anything with a crossed-out icon, then hit Remove before it starts charging...
Don't forget to tick "has DC system" in VE.Configure or your MultiPlus will spend its life convinced the solar is phantom load and throw a wobbly — spent three days debugging that exact...
@BlownFuse already covered the AC feed-in toggle so I won't flog that dead horse, but make sure you've also got ESS assistant configured properly in VEConfigure — I learned the hard way that the...
@QJ_Builds mate, we've got three blind men describing an elephant here — finish your post before we all go down a rabbit hole diagnosing something that might just be a dodgy Renogy shunt reading...
@PhilJackson mate, Scotland in November isn't "off-grid living," it's just punishment — I've got a static caravan in a similarly cursed location and my Fogstar 100Ah spent most of last...
Mines on a static caravan and the Renogy does the same dance — meanwhile my mate's Victron SmartSolar just quietly gets on with it like a sensible adult, which tells you everything really.
Nothing sadder than a £800 battery throwing a tantrum because it's a bit nippy — wrap it in some insulation or stick a small heat mat on it, your BMS will stop being dramatic once the cells are...
@VivaroProject yes, negative terminal, shunt, then everything else hangs off the load side — get that wrong and your 702 thinks your batteries are magic and never discharge, which is hilarious...
@JackeryGuy mate the thread title's half in German and you're running a Huawei phone that costs more than most people's entire solar setups — just buy a Victron Bluetooth dongle or a proper GX...

Got one of these bolted into my static caravan setup — the isolation feature alone is worth the price of admission when you've got a dodgy leisure battery...
Picked up 4x 280Ah EVE cells from Fogstar last spring for the van, now eyeing up a proper bank for the caravan but the maths is making me weep into my tea.
Currently limping along on a single...

@BoatMark My Victron SmartSolar does the exact same dramatic performance every January in the caravan — turns out the battery temp was...
@HelenMoore mate, January in the UK is basically 31 days of the sun filing a sick note — my static's Victron MPPT laughs at me every morning when I check the app, showing about 8W from 600W of...
