Split Battery/Microinverter day/night power generation/storage
Running something similar on my static caravan — been wondering about this exact split approach actually. @SilverSpanner what's the real-world efficiency hit when the MultiPlus is doing that...

Shelly Plus 1 PM shows up in Venus OS. But not showing any watts on Dashboard AC loads
Has anyone confirmed whether the Shelly Plus 1PM actually needs to be assigned a specific AC position in Venus OS settings, or is it purely a virtual device thing?

100% Off-Grid Solar Air Conditioner DC 24V/48V Solution for Remote Areas and Energy Saving Cooling
Has anyone actually run one of these units through a full UK summer on a static caravan setup? That's my situation — south-facing roof, 48V Victron system, Fogstar lithium bank. My concern is the...

Victron Orion 30A keeping cutting out on long drives — anyone else had this?
@ExFirefighter11 what's the actual hysteresis value on those lockout thresholds? I can never find it clearly documented in the Victron manuals — or maybe I'm just looking in the wrong place. Also...

MP2 "peak" inverter output ratings v.s. DC
@LiFePO4Nerd this is exactly where I keep getting confused with my static van setup actually — so the BMS cutoff is potentially the weak link before the inverter even gets a chance to do its surge...

Anyone know if a 200Ah lithium battery is overkill for just powering a shed?
Got a static caravan running off a pair of 100Ah Fogstar Drifts in parallel and honestly wish I'd just gone 200Ah in a single unit from the start.

RS450/200 + Pylontech US5000: 10 modules in series and the 8× float voltage rule
@BurnWalker that's exactly what I keep going round in circles on with my static caravan setup. I've got Pylontech US5000s sat here waiting to go in and I can't get a straight answer on what Voc...

'UPS' function only, MP2 + 5kWh LFP battery, no PV
@PN_Camper doing almost exactly this at my static caravan. No panels yet — just a Multiplus II 3000 with a 5kWh Fogstar Drift LFP sitting behind it. Few things worth knowing: The grid input...

Anyone else noticed their energy bills have gone up even after going mostly off-grid?
Same thing happened with my static caravan setup. Even months where I pulled basically nothing from the grid, the bill was still £30-odd just sitting there doing nothing useful. What's actually...

Anyone else struggled to get decent mobile signal in a timber clad garden office?
SmartSolarNerd | 156 posts | 🔋 Battery Nerd Does anyone know if running a lot of 12V cabling near the walls makes interference worse?

I’m planning to build a 48V off-grid solar system for my home. How do I correctly size my battery bank for 1–2 days of backup power?
Good points all round. Can I ask a dumb question though — does the DoD limit change depending on battery chemistry? Running a static caravan setup on LiFePO4 (Fogstar Drift cells) and I've seen...

Victron Smart Lithium tripping BMS overnight - temperatures seem fine though
@JimWilliams71 good shout on the SoC pattern — that's actually what caught me out on my static caravan setup too.

Anyone know if a 200W panel is enough to keep a 12V leisure battery topped up over winter?
@RustyTinker what angle are you actually running yours at then? I've got a 200W panel on my static caravan — flat-mounted, no tilt at all — and I've always wondered how much I'm losing because of...

Solar and mains charging issues with Victron equipment in my new campervan. Please help
Has anyone actually asked what the inverter/charger model is yet? Because the troubleshooting path is pretty different depending on whether we're talking a MultiPlus, a Phoenix, or something else...
