Running something similar on my garden office — generic 20A blue job, single 100W panel into a 100Ah AGM. Key settings I landed on: Boost voltage: 14.4V Float: 13.8V Boost return: 13.2V Low...

Great stuff @MarkGibson, congrats on getting it live! Six months of planning pays off eventually doesn't it. One thing I'd flag for anyone reading this who's about to do something similar —...

@SmartSolarNerd yes, and it's worth doing properly. Running mine through a Victron MultiPlus-II — the generator connects to the AC input, and the Multi handles the charging profile automatically...

Great thread! I've had a Cerbo GX running on my narrowboat for about two years now paired with a SmartSolar 150/35 and two 100Ah Fogstar Drift batteries.
Hey @HighlandNomad, a few things worth checking that haven't been mentioned yet. With a Daly BMS, I'd look at whether it's sending a premature charge complete signal — some Daly units can be a bit...

Hey @MeganStevens! Just to add to what @WD40Wizard78 was getting at — the key thing with MPPT over PWM on a 100W panel is you're typically recovering 20-30% more usable charge, which on a small...

Great timing for me to chip in — I've got both a garden office and a shepherd's hut running off solar so I've been down the shading rabbit hole more than once. The narrowboat roof is honestly a...

@BatteryDoug ran almost exactly the same setup in my van conversion — grabbed a JBD (also called Jiabaida) 4S BMS off AliExpress for about £12 and it's been rock solid for 18 months now.

Squib | 23 posts Not a garden office but my motorhome setup goes through similar winter struggles so I reckon the principles are the same.

LiFePO4_Guy | 2,156 posts Great thread — the Cerbo GX is absolutely worth it in my opinion, though I'd say the real game-changer nobody's mentioned yet is pairing it with VRM Portal for remote...

Ella1974 | 207 posts @LiamFox I had something similar with mine over the summer — worth checking whether there's anything generating interference nearby.

@MarkGibson good to see it up and running. What cable runs did you end up with between the panels and the MPPT?

Really useful thread — having a similar setup in my garden office (Multiplus 12/2000 on Fogstar Drift 100Ah cells) so following closely. One thing worth adding: have you checked the AC output...

Been running a 280Ah LiFePO4 bank (4 x EVE 280K cells) in my shed setup for about eight months now, paired with a JK BMS (the 200A active balancer version).

ThistleWalker | Posts: 312 @BrianKnight86 Worth considering what you'd actually gain from adding the relay.

So I've been tinkering with my Berlingo camper conversion for the past few months and I'm trying to keep costs sensible.

My static caravan was the gateway drug, but the van conversion is where the real space Tetris begins — swapped a Fogstar 200Ah for a slimline 100Ah just to reclaim a shelf, and honestly don't...

Lisa1978 | 847 posts | ⚡ Solar & Wind Great thread, @BreezyHermit. One thing worth adding — the temperature sensor placement inside the BMS can make a significant difference to when it...

Picked up 4x 280Ah EVE cells from Fogstar last spring for the van, now eyeing up a proper bank for the caravan but the maths is making me weep into my tea. Currently limping along on a single...

PanelNige | 412 posts Had this on my motorhome build — worth checking if it's dropping BT specifically during bulk charge when the active balancer is working hardest.
