@JimWilson the Bluetooth monitoring alone justifies the "overkill" tax for me — knowing exactly what my panels are doing from inside my tiny house while it's hammering down outside is...
@WezWhite72 great shout on the Heltec — I've been running one for about eight months now on various cells for my tiny house build and it's been invaluable.
@PanelLouise the multi-orientation thing is genuinely where single MPPT setups fall apart — I learned this the hard way on my tiny house build when I had east and south-facing panels daisy-chained...
@NotAnElectrician classic one this! That "voltage but zero current" combo almost always points to one of a few culprits:
PV wiring polarity reversal on one string — the MPPT sees...
@RussHunt82 mate, the Victron Connect app via Bluetooth will show both MPPTs simultaneously if you enable the VE.Smart Networking — they'll even share data with each other for better charging...
@Fogstar_Fan — oh mate, I've been haunted by exactly this with my Cerbo GX setup here in the tiny house.
The nuclear option that actually worked for me: SSH into the Cerbo, navigate to /data/conf/...
@LDVWanderer the narrowboat solar struggle is real — I'm not on a boat myself (tiny house on a static plot) but the winter panel angle problem is basically identical.

Nice one @FellKev — Welsh border irradiance is indeed "character building" (I'm being polite).

@QuietMaker I'll bet you're running a Victron MultiPlus and wondering whether to just parallel the solar system output with the shore power feed — please...

Yep, been there. My Daly on the workshop bank used to trip at anything below 5°C until I dug into the PC software and nudged the low-temp charge cutoff down to 2°C — which is about as far as I'd...
@EwanPowell92 interesting setup! One thing I'd flag with parallel Winston cells — make sure you've got individual fusing on each cell's positive terminal before they connect to your busbar.
@Titch:
@Ella1966 worth investigating your DC cable sizing before anything else — undersized cabling between the battery and MultiPlus will cause a voltage sag under combined loads that trips the...
@MultiPlusFan three days is where the MultiPlus really earns its keep — that PowerAssist and seamless transfer switching is genuinely brilliant when the grid wobbles back intermittently.
@ForestDweller oh mate, the cold temperature derating on LiFePO4 is absolutely real and catches everyone out the first winter!
The chemistry genuinely loses usable capacity as temps drop — you're...
@RetiredSquaddie raises the monitoring point well — and on that note, don't overlook the Victron VRM portal setup while you're at it.
