@DuctTapeDave60 parallel AGMs secondhand is already a headache waiting to happen — if they're not identical age and cycle history they'll fight each other and you'll kill the weaker one faster.

@LochSeeker mate I did the whole thing for £287 including a Fogstar 100Ah LiFePO4 (caught it on a flash sale), a Renogy 40A MPPT, and a secondhand Victron BMV-700 off eBay — the panel was the...

Picked up my Fogstar Drift 200Ah LiFePO4 back in spring and it's been brilliant all summer — easily hitting the full 200Ah and keeping my motorhome fridge, lights, and a small inverter happy for...

Hey @PeteDixon89 — worth checking whether it's actually a thermal thing causing the BT module to play up rather than just the MPPT being busy.

Not a narrowboat setup but I run a SmartSolar 100/20 in my shepherd's hut so similar ballpark. One thing nobody's mentioned — check your tail current setting in VictronConnect.

Your absorption timer is almost certainly cutting short because on a cloudy day the charge current never hits the threshold Victron uses to start the absorption clock properly — check your tail...

JimWilliams71 | Posts: 412 | Location: Derbyshire One thing nobody's mentioned yet — check your Victron panel's Vmp against the two Renogys before wiring that third panel in parallel.

CurrentAffairs replied: @HeatherWalker One thing nobody's mentioned yet — check your minimum SOC setting against your actual BMS cell floor.

Had this exact problem last winter in my shepherd's hut. JK was cutting out because the cells were reading below the low temp charge cutoff — totally correct behaviour tbh, it's protecting your...

@VitoProject had almost identical grief on my narrowboat when I added a Type 2 EVSE last spring. Few things worth checking: PowerAssist settings in VE.Configure — if your AC input limit is set...

BatteryPaula | 412 posts | 🐑 Shepherd's Hut Dweller My Fogstar cells in the hut spent last winter looking at me like I'd personally offended them every morning — slapped a cheap heat mat under the...

@TracyKnight I've been doing something similar for about 18 months now — charging a Nissan Leaf from a 2.4kW array with a Fogstar 300Ah bank.

George1972 | 134 posts Had exactly this with my MultiPlus 2 × 24/3000 — washing machine on a full 60°C cycle was causing nuisance trips during the spin phase specifically.

@Taffy62 worth checking your scheduled charging settings in ESS — easy one to miss. If you've got a time window set to charge from grid (maybe leftover from setting up an overnight Economy 7...

Great thread, and looks like @Jock30's original post got a bit chopped off — hopefully they'll fill in the blanks! To add something different to what @MarineGaz and @VE_Electric have already...

GarySmith58 | 847 posts | ⭐ Trusted Contributor @PhilFox99 Classic washing machine problem this — it's not the running watts that kills you, it's the motor startup surge.

Been running my off-grid cabin setup for about eight months now and it's been mostly brilliant, but I keep hitting an annoying snag.
