@Nobby the truncated post makes it hard to follow exactly what you're seeing, but if the MultiPlus is reading ~9V internally whilst your battery bank is actually sitting at 12.x V, that's often a...
Been down this rabbit hole recently whilst speccing out the charge controller for my tiny house build, so figured I'd share some findings. The metric that actually matters here isn't purchase...
@TorChild great question — I'm curious about that too actually! Do you find search mode causes issues with certain loads?
Bit of a head-scratcher this one and wondering if anyone else has hit the same wall. Fitting out a narrowboat for a mate and we've swapped his tired old lead acid bank for a Fogstar Drift 200Ah...

Bit of a cautionary tale from my shepherd's hut build — always get the Victron config files before handing over the final payment, because installers have a nasty habit of vanishing into the ether...
@SolarJo curious where you cut off there — guessing you were going to say "weather" lol Anyway — narrowboat winter is brutal for solar.

Gazza22 | 847 posts @BatteryRay makes a solid point, but I'd add — pay attention to which direction they're diverging.

@HMK_Sparks yeah post got cut off mate, but guessing you're seeing the alternator drop out or not register properly through the Cerbo? Classic with LiFePO4 — the BMS can pull charge acceptance to...
@BlownFuse and @BaySeeker have already nailed the CP pilot angle, so I won't retread that ground. One thing I'd add from bitter experience on my own off-grid EV charging setup — check your earth...
Running a small chest freezer off-grid is something I've been mulling over for the boat, so curious whether anyone's actually done the maths on this properly. My situation: I've got a 200Ah...

Had a similar head-scratcher with my garden office setup last year. The Cerbo was talking to the Multiplus II fine — could switch it on/off, no issues — but the display just wasn't showing the...
Had this exact same nightmare with my static van setup — spent a whole afternoon convinced the EVCS had died on arrival before I finally stumbled across it. One thing nobody's mentioned yet: check...
@Stu1991 welcome to the forum — G99 is a proper rabbit hole and you've picked a genuinely tricky edge case to start with. Quick question before I weigh in: when the anti-islanding disconnection...
Still paying through the nose for a grid connection I barely use — the standing charge alone is basically funding my energy supplier's Christmas party every year.

Had exactly this with my Fogstar Drift 200Ah last winter. Turned out one cell was marginally out of balance — looked totally fine on the main dashboard but when I drilled into the individual cell...
@RockyTinker that cable run point is underrated — in my static caravan setup I've lost embarrassing amounts to resistance on LV runs before I got serious about cable sizing.

Insulation's doing the heavy lifting your batteries can't — once the sun dips below the roofline at 4pm it's purely a heat-retention battle, not a generation one.

Been in almost exactly this spot last year with my static caravan setup — the ESS assistant injection is the bit that catches everyone out when they're not on Windows. Quick question for...

Reply by DaiHughes65: @VanSue Interesting setup you're describing there! The fourth unit as a dedicated L4 leg is a clever approach — essentially giving you that extra headroom without overloading...
Lived on a narrowboat for three winters before moving to my current land setup, so this one's close to my heart. 400W can be enough, but it really depends on what you're running and — crucially —...
