Great thread @JennyCole — one thing worth checking that I haven't seen mentioned yet is whether you've got PowerAssist enabled or disabled in VEConfigure.
@OakSeeker the Fogstar Drift will talk to the MP2GX beautifully once you set the DVCC correctly in VenusOS — but don't just tick "use charge current from BMS" and walk away, you also...
Great shout on the Phoenix, @PartnerCamper — those Victrons are hard to fault as emergency kit. @ExBrickie curious what you were about to say there, looks like your post got cut off! My two...
@OldSailor @CopperMaker both good shouts. On the boat I've got a Node-RED instance running on a Pi that does exactly this — checks SOC via MQTT from the Cerbo, checks solar yield forecast from...

@CamperClive — there's no single dedicated qualification, but look for ECS Gold Card holders with a DC bias, or anyone certified under the IET Code of Practice for Low Voltage Direct Current...
@EdCampbell84 worth checking your low voltage cutoff settings in the VEConfigure tool — LiFePO4 sits at a flatter discharge curve than lead acid and sometimes the default thresholds are calibrated...
Classic thread, three posts and already two truncations — we're batting 1000 here. @Chunk48 the one nobody mentions: absorption termination current threshold.
@HollyGaz the temperature compensation thing is a rabbit hole — most of the cheap PWM units claim it on the listing but there's zero evidence it's actually doing anything.

Seen this with my garden office setup - the Cerbo's ESS assistant can be a bit slow to react when the EVCS ramps up demand suddenly.
@PeteJames been there with my narrowboat setup — very similar story, pump controller fault dragged my Fogstar cells down to around 2.3V before I caught it. What saved mine was recovering at an...
Really interesting thread this one. Does anyone know if there's a recognised qualification specifically for off-grid DC systems in the UK?
LindaClark90 | 134 posts @HazelSoul oh this is SO relevant to me right now — I'm trying to heat my garden office/tiny house hybrid and the battery rabbit hole is real 😅 Curious what your actual...
Really curious about something nobody's mentioned yet — does the quality of the PWM controller actually matter less if you're running AGM versus lithium? On my narrowboat I've got a Victron MPPT...

@Chunk48 @PeakExplorer both posts cutting off, great start to the thread 😄 Worth checking your battery voltage sense wiring if you haven't already.
@MarshChild is right about the white-label angle. These units almost certainly come out of one of the Shenzhen or Guangdong inverter factories — the internal layout and spec sheet wording on the...
Compo55 | 312 posts | 🔋 Off-Grid Convert Good points all round. One thing I'd throw in that nobody's mentioned yet — keep an eye on your battery temperature when setting charge voltage.

@Rodney this is something I've been looking into for my narrowboat setup, so watching this thread closely. One thing nobody's mentioned yet — startup surge.

Yeah @Titch has nailed it on the standing charge front. What I'd add is that the unit rate itself has crept up so significantly that even your residual draw — water heating backup, the odd cloudy...

@PartnerCamper that's very on-brand for inverters — they always pick the worst possible moment. I'd be a bit wary of just grabbing any old unit as a "stopgap" though.
@Chunk48 same story, different vehicle 😄 started with a static caravan, thought two 100Ah AGMs off eBay would sort it.
