GillGibson | 1,204 posts | 🔋 Battery Nerd @BatteryBarry one thing that trips people up at this stage — don't forget to factor in your inverter's idle draw when doing the calc.

Hey @DevonCruiser, good setup you've got there! One thing worth mentioning that nobody's touched on yet — keep an eye on your battery's BMS discharge rating.

Just got mine installed on the boat last month and still not sure I've squeezed full value out of it.

ThistlePaul | 312 posts | 🔋 Off-Grid Convert @Finn1975 Worth checking your BMV-712's shunt wiring too - specifically whether everything on the negative side is routed through that shunt.

Been running EVE cells for about 18 months now — slightly different configuration, 8 cells in series for 24v with a Daly BMS rather than JBD, but similar ballpark cost. One thing nobody's...

AndyReid | 847 posts @Curly, 4m is getting on a bit for 70mm² at 12V — that's where I'd start looking.

@SamWhite the relay is dead weight at this point, honestly. The Orion-Tr is doing everything the relay used to do but properly — it's presenting a controlled load to the alternator rather than...

GrumpyWarden | 47 posts Running something similar on my garden office — 200W Renogy panels with a Fogstar battery.

@ExBrickie31 welcome to the forum, great first post and a solid setup to be working with! Classic symptom this — almost certainly your absorption voltage or tail current settings in VictronConnect...

@BayPete is absolutely right on the temperature coefficient point — worth knowing that most standard poly/mono panels lose roughly 0.3–0.5% per degree Celsius above 25°C STC rating, so a hot...

@JimWilliams71 worth checking your battery cable connections as well — specifically the ones between the MPPT and the battery terminals.

Hey @Kate1970, don't despair! January in the UK is genuinely the worst month for solar - low sun angle, short days, and seemingly endless cloud cover.

PW_Sparks | 203 posts @KangooSolar worth checking your Daly's low-temp charge cutoff setting in the app — they often ship with it set around 5°C from the factory, which would explain a 4°C cutoff...

Worth mentioning the EV angle here — I use my bank for overnight trickle charging a small EV via a 13A socket, so the batteries are cycling pretty hard daily.

Currently mid-build on my Transit-based motorhome and stuck on MPPT controller choice. Running a 400W panel array (2x200W in series) into a 12V 200Ah Fogstar Drift lithium bank.
Ran a similar budget PWM on my garden office build for the first year — worked fine until it didn't.

@SaltyMaker this is exactly what's pushing me to finally sort out my cabin setup too. Quick question though — did you need to add a BMS separately with the Fogstar Drift, or is one built in?

@Amy2000 replied: @EcoFlow_Gal I went through exactly this dilemma last year for my off-grid shed setup!

Solid thread this — and @Turbo, for a first post you've stumbled into exactly the right kind of debate!

Been pulling my hair out this past week with my 280Ah LiFePO4 bank (8 x Eve 280Ah cells in 8S configuration) and a JK BMS — the 200A active balancer version.
