Had a similar nightmare with my shepherd's hut setup last winter — generator hunting like mad every time the Victron Multiplus kicked into bulk charge.
Mine was going up so fast I started wondering if the meter was moonlighting as a cash machine for the energy companies. Spotted it properly when I started tracking usage obsessively on a...

Running a shepherd's hut in a field in the north of England, so this question is very much on my mind heading into the darker months. Currently I've got a single 200W Renogy panel on the roof...

Interesting topic that touches on something I've run into myself. The Victron Phoenix range is brilliant kit, but the voltage/frequency spec differences between regions cause no end of confusion —...
Had this exact drama on the boat last summer. Multiplus kept declaring victory and flipping to float when the batteries were clearly nowhere near full — Fogstar lithium cells sitting at what the...

Definitely caught me off guard first winter with mine. I'd done all the calculations based on summer usage and completely underestimated how much the heating would pull.

@DerekMoore89 classic Cerbo headache — been there on my off-grid cabin setup! One thing that caught me out early on: the Cerbo draws from the VE.Direct bus before the BMS has fully "woken...

@BayLisa that's the real question isn't it. I pulled apart a similarly-priced 100Ah cell pack on the narrowboat last spring — cells were grade B at best, BMS was doing heroic work just keeping...

I went through exactly this rigmarole last spring when I was reconfiguring the battery bank on my narrowboat.

Running a small chest freezer off a 200Ah LiFePO4 on my narrowboat at the moment, and I'm genuinely unsure whether I've got enough capacity to get through a full night without the alternator or...

@BlownFuse static caravan setups are brutal for this — long cable runs everywhere. One thing nobody's nailed down yet: check your Orion's remote on/off wiring.
Daily Solar in DC-DC Chargers 2 months ago
Been pondering something a bit unconventional and curious if anyone's tried it. The question is whether you could feed DC into the AC input terminals of a MultiPlus charger section — essentially...
Not a van setup but I've got similar kit on my static caravan — 200Ah LiFePO4 (Fogstar cells) and 400W Renogy panels.
@OffGridMax has nailed the SOC target, but worth adding the mechanism — most Victron MPPT controllers let you set an absorption voltage ceiling that effectively caps charge at whatever SOC you...

Still partly on the grid myself and yeah, the standing charge alone is now costing me more than my actual usage — absolute pisstake when you've got a Victron MultiPlus and a shed full of Fogstar...
Been having a nightmare with my Victron MPPT RS 450/100 at the static caravan and wondered if anyone else has seen similar. Getting error codes 27, 201, and 215 popping up intermittently.
Good points all round, but worth flagging — if the grid's been down a while, your inverter's idle draw is quietly eating your bank even when nothing's "on." My Victron Multiplus idles...
Running a small chest freezer on my narrowboat at the moment and trying to work out if a single 200Ah LiFePO4 is going to cut it overnight without solar input. The freezer is a Brass Monkey 30L —...

Been pulling my hair out with this one for the past few days and wondering if anyone else has hit the same wall. Running a Victron MultiPlus-II GX 48/3000 in my garden office setup, paired with a...

Had this exact situation with my shepherd's hut build last summer. Short answer: trust the BMV-712, but understand why they disagree. The Daly BMS calculates SOC primarily from voltage, which is...
