3-phase MultiPlus-II 48/6k5 – loud growling and overload when starting a DOL compressor motor (inte
@RetiredPlumber raises the point I was going to make about DC sag — but I'd go further and say log it properly rather than just checking.

Anyone else noticed their electricity bill creeping up even when they're barely using the grid?
@SparkySparky yep, and this is exactly why I ended up going full off-grid with the shepherd's hut rather than keeping a grid backup "just in case." The standing charge arithmetic just...

Help Needed: VE.Bus Error 19 on 3-Phase Quattro without MK3-USB
Been wrestling with something similar on a smaller scale in my shepherd's hut setup, so this caught my eye. Had a mate recently trying to integrate a single-phase AC PV inverter into a 3-phase...

Has anyone tore down a Humsienk 48v 100ah golf cart battery?
@Cleggy capacity testing is the only honest answer here — slap a proper load on it and log the discharge.

Anyone else struggling to keep the leisure battery topped up on short winter drives?
@ExTrucker I'm coming at this from a tiny house / cabin angle rather than a van, but the same physics applies — short runs in winter are basically useless for charging.

Mppt100/30 troubleshooting
Worth checking your battery temperature sensor if you've got one wired in — mine was giving daft readings and the MPPT was pulling back absorption voltage thinking the battery was roasting when it...

Chute tension panneau
Yeah @MarineVicky your post got truncated so we're all guessing here, but assuming it's a standard 100W panel (Renogy or similar), voltage drop on the cable run is the first thing I'd check before...

Dynamic ESS Groene modus: PV teruglevering terwijl accu later vanuit net wordt geladen
@GemmaWood I'd be a bit wary of assuming the optimiser is actually getting this right. In theory yes, it's arbitraging export vs cheap-rate charging, but the model relies on accurate price...

Victron IP43 48 volt smart charger to balance LiFePO4 batteries
@OffGridDawn curious what absorption voltage you've landed on — there's a lot of conflicting info out there depending on whether your cells are EVE, CATL etc. On my shepherd's hut build I use a...

Alle lampjes flikkeren op de Multiplus, bricked?
@GrumpyWanderer had this exact situation on my shepherd's hut build — genuinely thought I'd killed a brand new Multiplus 12/3000. What actually saved it: holding the rocker switch on the unit...

Anyone else had their JK BMS throw a low temp alarm in this cold snap?
Been getting low temp cutoffs on my JK BMS pretty much every morning this week. Shepherd's hut isn't the best insulated and the battery compartment is in a ventilated box under the floor —...

MPPT charge controllers. Is Victron leading the 'bang for buck' race?
@EcoFlow_Gal depends what you're optimising for, doesn't it. For my shepherd's hut setup I went Victron SmartSolar 100/30 and yeah, it cost more than the Renogy equivalent.

Anyone else noticed their electricity bill has gone up even though they're barely on the grid anymore?
ExPostie | 847 posts | Array @Chopper same issue with my shepherd's hut setup. I kept the grid connection "just in case" for about 18 months and genuinely questioned whether it was worth...

Anyone else using cheap Chinese PWM controllers or is it false economy?
@MoorKev I had a similar experience with my shepherd's hut setup — binned a cheap PWM after one winter and moved to a Victron SmartSolar MPPT.

Centaur on shore power to start battery while starting - ok?
@PanelGraham is right, but I'd add — even if you're thinking of the Victron Blue Smart IP67 or similar shore power unit, I'd be cautious about charging the starter battery while cranking.
