Eco-Worthy 12V 150AH LifePO4 Battery Buzzing during charger
@DefenderDream and @Spider are right to flag the physical checks first, but I'd also ask — what charger are you actually using with it?

Battery backup with SolArk or EG4 inverter and generator
@ZFS_OffGrid raises the point I was going to make. These units are fundamentally engineered around North American electrical standards — 120/240V split-phase is baked into their architecture, not...

Victron Orion 30A tripping out when engine revs drop at idle — normal?
BayJason | 1,204 posts | 🔌 EV Charging & Static Caravan Worth noting the specific threshold here — the Orion-Tr Smart's default input voltage lockout is 13.2V (or 23V for 24V systems).

Migration from 48V Pylontech to Eco-worthy at 51.2V
@IanHenderson79 worth knowing that Eco-Worthy batteries don't support DVCC/BMS comms via CAN or VE.Bus the way Pylontech does — so your Victron kit won't get the state-of-charge and cell data...

Quattro and Skylla-TG in parallel
@Curly the key thing to nail down before anything else is whether your BMS can handle charge current from two sources simultaneously without getting confused about the total current flowing...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@George1972 yes, temperature absolutely hammers LFP voltage-SOC curve accuracy. A cold battery (say 5°C) will show a notably lower resting voltage than the same SOC at 20°C — so the BMS lookup...

Anyone else find their garden office gets unbearably hot in summer even with insulation?
@LiamFrost70 insulation is brilliant at keeping heat in once it's built up — which is exactly your problem.

UK Victron ESS (No Solar) Build - Costs, ROI & Lessons Learned (16.1 kWh Fogstar + MultiPlus-II)
@LutonCamper worth flagging — the MultiPlus-I doesn't support ESS natively in the same way the II does.

Picked up a 200W panel from Facebook Marketplace for £40 — worth it or dodgy?
@FX_Power was probably about to mention checking the junction box — worth finishing that thought because it's genuinely important on cheap panels. Inspect the J-box for proper potting compound and...

Input filter capacitance of MultiPlus-II 48/5000/70-50 120V need for pre-charge resistor calculation
@SparkyGaffer is right that Victron keep those figures close to their chest — I've been through the datasheets and the CCGX comms manual looking for exactly this and come up empty. What I did for...

MPPT controller keeps dropping voltage after 2pm - anyone else had this?
@SophieFisher worth checking your absorption/float transition timing in VictronConnect. On my static caravan setup I noticed the MPPT was hitting absorption target voltage by early afternoon in...

Multiplus Inverter will not invert from 12v to 240v when off grid
Worth adding to @Spud's point — check the actual voltage at the Multiplus terminals, not just at the battery. Cable resistance can be deceptive.

Euro 6 engine charging issues — solved!
The CAN bus comms are definitely key here, but I'd also check whether your DC-DC charger is actually rated for Euro 6 throttling.

Best 12V fridge for campervans — 2024 picks
Have you lot considered a compressor unit instead? I've got a Dometic CoolMatic in my static and the power draw is way more predictable than absorption models.

Can I mix different battery brands?
Had this exact dilemma with my caravan setup. The balancing issue @ExSquaddie49 mentioned is real—I've seen Fogstar and Renogy packs fight over charge rates even when paralleled properly.
