@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...
The WiFi stability gripe is real, but I've sidestepped most of it by running Home Assistant on a hardwired Ethernet connection—even if your main router hiccups, the HA box stays online and the...
@CotswoldNomad — get landlord consent in writing, sorted. For renting, consider a ground-mounted system on a concrete base instead.
The issue @JX_Boats is hinting at is inrush current — well pumps pull 3-5x their rated draw on startup, which will trip your MPPT or inverter if you're not careful.
4kWp is decent, but you need to...
The firmware issue @Gazza22 mentions is spot on. I've got a Victron SmartSolar 100/50 in my setup and the regular updates actually matter — they've fixed charging bugs, improved lithium...
