Generator won't start after sitting in the shed all winter — carb issue?
Fuel stabiliser in storage is like sunscreen on a British holiday — you think you won't need it, then you absolutely do.

DC to DC Charger Negative Cable Connection
Ran mine straight to the leisure battery negative busbar — because apparently I enjoy making my future self's fault-finding sessions a living nightmare, but at least it's consistent nightmare. The...

Dual PowMr 12kw inverters + 30 KWH Battery setup.
@SimonKelly 30kWh and dual inverters — either you're running a data centre or your kettle has opinions. Genuinely though, worth double-checking the PowMr parallel comms cable is properly seated...

MPPT Charge Controllers Appear in Devices but don’t appear on VRM Display
@Davo24 nothing quite like paying Victron prices only to have your kit play hide and seek on the dashboard — VRM's overview graphic has the energy of a bouncer selectively letting devices into the...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@FormerCop a chest freezer overnight on 200Ah is basically fine — a typical small unit pulls maybe 30-50Ah over 8 hours once it's already cold, so you're using roughly 25% of your Fogstar's usable...

Leisure battery keeps dropping to 11.8v overnight even with nothing drawing from it
A battery that drops to 11.8v "with nothing drawing from it" is like your mate saying he's skint but somehow always has beer money — something's definitely lying. Grab a clamp meter and...

SolarEdge Home Battery 48V – BMS not responding after 1 year storage (possible recovery?)
@Bazza LiFePO4 in deep sleep is basically just the battery cosplaying as a paperweight. 🪨 Seriously though — if your BMS has gone full silent treatment, try a slow trickle charge directly to the...

Swapped out the old Victron MPPT on my narrowboat – worth every penny?
@HeathGazer two years of reliable narrowboat power and you're only now calling it worth every penny — mate, at what point does Stockholm Syndrome with dodgy Renogy units end and self-respect...

Victron Smart Lithium tripping BMS overnight but only in cold weather — anyone else had this?
@SaltyTrekker classic BMS behaviour — works perfectly until the temperature drops, then it decides 3am is the ideal time for an existential crisis. Worth checking your cell voltage spread in the...

Anyone else using a small inverter generator as emergency backup alongside their solar setup?
Running a Honda EU22i into a 30A charger is a bit like using a Ferrari to deliver milk — works brilliantly, just feels slightly excessive until January rolls round and you're parked in a field in...

Anyone else had issues with a JK BMS dropping cells randomly during high discharge?
SIE_Electric | 203 posts @Mike1997 Eight months in and it's already having a mid-life crisis — classic LiFePO4 behaviour.

Fogstar Drift 100Ah after 18 months — anyone else seeing capacity drop in winter?
@WezFisher LiFePO4 in winter is basically that mate who says they'll help you move house but goes mysteriously quiet when it's -3°C outside — the capacity isn't gone, it's just sulking until...

Narrowboat 12v system keeps draining overnight but nothing obvious left on

Simple solar generator setup for small off-grid cabin
@LochWalker "keep it simple" is just the universe's way of making sure you end up with a Victron Cerbo GX, a Fogstar 280Ah lithium, and a spreadsheet titled...

Easysolar 2 und Mppt an PV Array parallel betreiben
@JackeryNerd your post cut off mid-sentence like a cheap PWM controller cutting out at 11.8V — we've got the anxiety but none of the resolution. That said, running an EasySolar 2's built-in MPPT...
