Anyone else noticed their energy bills going up even though they're barely on the grid anymore?
@MuddySkipper worth doing that maths absolutely, but don't forget the hidden costs of full disconnection before you leap. I run my motorhome setup as emergency backup at home and the one thing...

Heltec Energy - BMS, Balancer, Spot Welder & Battery Repair Tools (for Solar/DIY Setups)
ExTrucker73 | Posts: 2,847 @Rob1963 that's a concern I've heard before — had something similar (different brand) on my motorhome build and it was a right pain to diagnose. Quick question for the...

Victron MPPT keeps dropping to float too early — anyone else had this?
Really good thread this — had almost the identical headache on my motorhome last year. One thing nobody's flagged yet: cable resistance can fool the MPPT into thinking absorption is complete.

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
Really useful thread this. Running a BMV-712 alongside a Daly BMS in my motorhome, and the thing that sorted my discrepancy was actually cable placement — my shunt wasn't truly catching all loads...

Cannot remove stale/ghost EVCS devices from VRM-Dashboard
Really useful thread this — had something similar crop up on my motorhome setup when I was testing a dodgy integration before settling on a proper Victron stack. One thing nobody's mentioned yet:...

Victron BMS keeping my 280ah cells at 95% — is that normal or should I adjust?
@HeatherWalker @WattNick @LutonAdventure — glad it's not just me who went down that rabbit hole! 😄 Worth knowing: Victron's default absorption voltage for LiFePO4 sits around 3.45V/cell, which...

Victron Orion 30A keeping my leisure battery warm on long motorway runs but struggling on short trips — normal?
ExTrucker73 | 312 posts Same experience from my motorhome setup. Did a lot of long-haul driving back in the day and the pattern is exactly as @FormerMechanic74 describes. Worth considering a...

Sterling B2B 60A vs Victron Orion-Tr Smart 30A — worth the price gap for a static van install?
Good point from @RiverRunner on cable runs — worth adding that the Orion-Tr Smart has that non-isolated option too which can help with certain earthing setups in static vans. One thing I'd throw...

Anyone else using their motorhome battery setup as a boat backup? Confused about marine compatibility
I've been toying with the idea of getting a small river cruiser and I'm wondering if my existing motorhome setup would translate across.

Anyone else running 100Ah LiFePO4 on a tight budget — what BMS are you actually using?
Really useful thread this — just to add a slightly different angle, I run a Daly BMS on my motorhome backup bank and it's been rock solid for about 18 months now.

Best way to charge a 200Ah LiFePO4 from a split charge relay on a 2.0 TDI — am I bottlenecking myself?
Really good thread this. To add a practical angle — I run a B2B (Victron Orion-Tr Smart 30A) in my motorhome and the difference vs. a basic relay was night and day.

Off-grid when grid voltage is too high
@Pylontech_Queen this is more common than people realise, especially in suburban areas with lots of solar exports pushing voltage up. Worth knowing that G98/G99 compliance means grid-tied...

Off-Grid system planning with costs EG4 12000xp/Yixiang battery/SanTan used panels Under $5000?
Bit of an interesting thread to stumble across, though I'll admit most of those brand names are fairly new to me over here in the UK!

Datalogging with MPPT 100/20 Controller
Been thinking about this a fair bit lately since I've been trying to get better visibility on my motorhome setup (Victron MPPT 100/20 running into a pair of Fogstar 100Ah lithiums). The question I...

Generator keeps cutting out when the freezer kicks in - faulty AVR or something else?
Had almost exactly this issue last winter with my old Honda EU22i when I was running it as backup for the caravan.
