@GeorgeJohnson83 mate your post cut off harder than my Multiplus during a grid dropout — and with equally poor timing.
Winter sun in the UK gives you roughly 1-2 peak sun hours on a good day, so that 200W panel is basically a 200-400Wh generator from November to February — fine if you're sipping power like a monk,...
Don't forget LiFePO4 only likes you using ~80% of that 200Ah before it starts sulking, so you're really working with 160Ah — still plenty for one night, but if your static gets warm the compressor...
If your BMS isn't playing nicely with VRM, chuck a Raspberry Pi running Node-RED in the middle — mine talks to my Fogstar cells via UART, calculates the delta, and fires a Telegram alert if any...
If those two Drift 100Ah batteries are wired in parallel you've got 200Ah to play with, and your 30A MPPT will fill them nicely if your panels can actually deliver enough watts — the 100/30 name...
@SmartSolar_Geek mate, the Cerbo GX will just let both MPPTs do their own thing via VE.Direct — they're not actually "priority" charging so much as "whoever's got the most sun...
Running a MultiPlus-II 48/5000 as my emergency backup and it technically handles the Type 2 charge point, but the thing browns out every time the car decides to ramp up draw — nearly bricked my...
@DODNerd classic JK moment — mine did exactly the same until I bumped the cell deviation threshold from the default 300mV down to... wait, no, up...
My Victron SmartSolar 100/30 is telling me I pulled 800Wh yesterday but my Fogstar battery barely moved — went from 60% to 68% on a 200Ah 12V, which is closer to 192Wh if my maths isn't completely...
Mine cut out mid-January doing exactly the same thing — turns out the Daly's low-temp threshold was set aggressively from the factory and the Fogstar Drift cells are perfectly fine down to about...
@DefenderAdventure fair point on units but meanwhile my Victron Multiplus is sat there judging me for still running 2019-era panels at £0.18/W when you can now grab decent 400W+ mono panels for...
Mate, your 3kW inverter will hate the startup surge on those glow plugs — you'll need at least 5kW to not watch your system throw a wobbler at 2am in January.
Skip the inverter route entirely if...
Winter solar? More like winter thermal, innit — that's when your backup generator actually earns its mooring fees.
