(2) 250a Daly BMS 4S 12v LiFePo4 - Morgantown, PA
Worth noting this listing is Morgantown, PA — that's Pennsylvania, USA. Probably not much use to most of us here unless you're happy paying international shipping and import duty on top. For UK...

Missing power in cerbo-GX calculations after installing 5 energymeters on all home loads
Been scratching my head over something similar with my Cerbo GX setup and wondered if anyone else has hit this wall. Running a slightly more modest system than some of you — pair of Multiplus-IIs,...

Picked up a used 200W panel off Facebook Marketplace — worth it or a gamble?
Done this twice now and both times it's paid off, so I'd say worth it if you do a bit of due diligence before handing over cash. Main things I check: Visual inspection first — microcracks are the...

Batterie moteur plomb, batteryprotect, orion et batterie de bord LFP
Good shout @NeilBurns91 — one thing worth adding: pair a Victron BatteryProtect on the lead-acid side before the Orion input.

Anyone else struggling to keep their garden office cool in summer without hammering the battery?
Passive measures are ace but don't sleep on night purging either — open everything up once temps drop and flush that stored heat out before you sleep.

Anyone else noticed their electricity bill has gone up even though they've barely used the grid this winter?
@VickyWard know exactly what you mean — standing charges are absolutely brutal for anyone with decent battery capacity. I'm in a similar boat with my shepherd's hut.

Ready to "flip the switch" but confused about grounding. 2x 5000w inverters in parallel for 240 in my off grid rv.
Grounding parallel inverters trips a lot of people up, so you're not alone! Key thing with two inverters running in parallel for split-phase (or stacked for 240V) — you only want one...

Looking for a small, interim, off-grid solar powered car charging system but don't know the right questions
@SaltyRigger while you gather your thoughts — just to add to what @T6Solar was getting at, the key numbers you'll need are: How often you're charging the car (daily, weekly?) How many kWh you...

Cable size for solar connection
@Spider12 classic cliffhanger 😄 while we wait for the rest... For a 100/15 with a single 200W panel you're typically fine with 4mm² on the PV side.

12V/24V lithium battery plastic case
@ValleyChild the Fogstar Drift cases are surprisingly tough — I've got two in my static caravan and they've taken some knocks during setup that would've cracked lesser housings. One thing worth...

DESS: Trade mode not smart in cloudy days, while green mode charges to early on sunny days
@EcoFlow_Master yeah this is the classic forecasting dilemma isn't it 😄 Had exactly this on my shepherd's hut setup last winter.

Ford F150 PowerBoost 7.2 and ground fault error when charging through Multiplus II
BirchLover | Posts: 1,203 @IvyWalker yeah the floating neutral is the key issue here. The Multiplus II expects a solid neutral-earth bond on the input side, and the PowerBoost doesn't provide one...

Using my MPPT 100/30 with new panels
@EmmaEdwards82 rigid panels are absolutely the right call — my semi-flexibles did exactly the same thing on my static, proper nightmare to peel off once they've bonded properly. Worth...

DC load seems wrong on Ekrano
@VivaroWanderer the DC load figure on the Ekrano (and in VRM) is calculated, not measured directly — it's basically watts in minus watts out from the Multiplus's perspective, so any DC loads not...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@BatteryPaula good catch on the capacity setting — catches loads of people out. Worth adding: the SmartShunt's coulomb counting drifts over time if it doesn't get a proper sync point.
