@Turbo34 worth knowing that LiFePO4 genuinely shouldn't be charged below around 0°C — the BMS is actually doing its job there, not misbehaving.

BurnSophie | 247 posts | Array Three days on the cut last February taught me exactly this. Heating was the thing that nearly broke me — I'd been running a diesel Webasto but the controller pulls a...

My Fogstar 280Ah cells are wired up to a Pi Zero 2W running Node-RED and honestly it's the most satisfying rabbit hole I've ever fallen down — until 2am hits and you're debugging a MQTT broker...

RobWebb59 | 1,847 posts @WayneTaylor One thing nobody's mentioned yet — have you got your battery type set correctly in VictronConnect?

MarshPete | Posts: 847 @CotswoldCruiser nice setup! The Victron/Fogstar combo is solid — I ran something similar in a converted horsebox for about eight months before upgrading. One thing worth...

@CotswoldCruiser solid setup — the 100/30 is a decent controller but at 400W input you're brushing against its limits on a good day.

Stacey26 | 178 posts @PanelLouise I had almost identical bother with mine, though it was a smaller inverter rather than an EVSE causing the trip.

I've been scratching my head with this one for a couple of weeks now. Running a 16S 280Ah LiFePO4 pack (EVE cells) in my shed setup, managed by a JK BMS (the 200A active balancer version).

Finally getting round to building a proper insulated garden office at the bottom of the garden and I want to do this right from the off.

VanAmy | 312 posts @BreezyDrifter that's almost exactly my situation — narrowboat has 400Ah of Fogstar lithium as the primary system, van conversion acts as overflow/backup when I'm moored...

@OldSparky18 worth checking whether those lower-capacity cells are actually underperforming or just haven't been through enough charge cycles yet.

PartnerBuild | 847 posts Worth adding something nobody's touched on — cable length matching between your two controllers and the battery. I learned this the hard way wiring my shepherd's hut...

Fogstar cells talking natively to the Cerbo via a Daly BMS and a cheap RS485-to-USB adaptor — works a treat until it doesn't, then you're debugging at midnight in a field wondering why Node-RED...

ValleySolar | 412 posts @Jim1999 Something worth considering that nobody's touched on yet — where are you parking overnight?

OwenYoung83 | 312 posts @SprinterWanderer done exactly this on my 57ft trad last summer — fitted 400W across the roof and genuinely haven't run the engine purely for charging since May.

@StuKnight — orientation makes a massive difference in my experience. I'm running 200W fixed on the motorhome roof, which is rarely perfectly south-facing once I've parked up.

Declan1985 | 47 posts @DuctTapeDave62 Nice setup! One thing worth knowing with the Orion-Tr Smart in parallel — they don't actually communicate with each other like the Multiplus units do, so you...

Been living aboard my narrowboat on the K&C for about eight months now and I'm tearing my hair out with my solar setup.
Hamish Taylor in Marine & Boat 6 months ago thumb_up 5
What @Jonno said rings true from my narrowboat days. The real killer with LiFePO4 specifically is that flat voltage curve — the battery sits at roughly the same voltage from about 20% to 80% SOC,...
