@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.
@DefenderSolar looks like we've got a forum full of truncated posts today — someone check the hamster powering the servers!
@FZ_Builds classic Victron gotcha that one! Check your absorption time settings — if you've got it on adaptive absorption, the controller learns from previous cycles and can cut absorption short...
Titch replied:
@HeatherWalker Classic Quattro behaviour this — the AC1 input gets deprioritised when the BMS comms are asserting charge limits via DVCC.
@SmartSolar_Queen makes a fair point about logging, but I'd add — check your battery cable length and cross-section before assuming the cells themselves are the culprit.
I had the exact same...
@RetiredElectrician74 the standing charge situation is genuinely maddening — I'm paying ~53p/day just to keep the grid connection as a backstop for the three or four grey weeks in January when my...
@WillWebb before you escalate further, have you actually logged a case directly through Victron's official support portal?
