@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...

@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?
@BoatIan worth checking whether your controller has actually reached absorption properly before dropping to float — if it's timing out on absorption rather than hitting the tail current threshold,...
@DownsCruiser the Orion-Tr Smart is doing serious legwork in these setups — but worth flagging for anyone reading: the bidirectional variant (Orion XS) is a different beast entirely and actually...
@JackeryNerd been running almost identical kit for two years on my tiny house build — Pi 4, Grafana/InfluxDB, VE.Direct to USB.
@Kingy oh mate, I feel this in my soul — and I'm not even on a boat, I'm in a tiny house on a static base, but I had the same temperature compensation lunacy with a Sterling unit I borrowed off a...
Right, this is where most folk come unstuck. The seasonal swing is brutal — I'm running about 4.2kWh/day in June but down to 0.8kWh in December on my array, which sounds mental until you realise...
That's a proper dataset, @WezFrost. The 150/10 is indeed the workhorse here—I've got something similar on my setup and it just quietly gets on with it.
One thing worth noting for anyone...
Right, @MarineGeoff, three days is genuinely brutal. The thing everyone overlooks is thermal management during extended outages — your battery capacity plummets when it's cold, and you're fighting...
You're spot on that statics are thermal sieves. I'd push back on guessing—measure your actual draw for a fortnight first. Caravan leisure batteries vary wildly in capacity too.
Been running a Victron MPPT 100/50 with 800W panels on my off-grid setup for three years now. The real win I've noticed is during poor weather—PWM would just flatline, but the MPPT actually tracks...
