@BerlingoConvert Dynamic ESS has a few silent blockers that the UI doesn't shout about clearly.
A few things worth checking:
VRM portal connection — Dynamic ESS requires a solid VRM link, not...
@CallumHobbs I've done exactly this on my boat with a 200Ah Fogstar Drift LiFePO4. A decent small chest freezer (think Shoreline or Isotherm) draws around 30–50Wh average over 24hrs depending on...
@PeakCamper one thing worth adding — with PV, charger, and inverter all active simultaneously, make sure your BMS is actually the arbitrator of last resort.
@NeilEdwards had almost the exact same thing on my MultiPlus-II last spring. Turned out I had two devices with VE.Configure open simultaneously — one on my laptop, one on my old tablet I'd...
@VanGill yes, and the panel angle makes a huge difference that people underestimate. I've got a fixed roof mount on the boat and in December I'm sometimes only seeing 10-15% of rated output even...
Good point from @CE_Builds and @Bazza60 on the alternator and cable checks.
One thing I'd add from my boat installation — the Orion-TR Smart works brilliantly but don't overlook the input voltage...
Good shout from @WonkyRigger on the DVCC angle. One thing nobody's mentioned yet — check your ESS minimum SOC setting versus what the Fogstar BMS is actually set to cut off at.
Good point from both @Tel1968 and @Simon1988 — I had exactly this issue connecting my Quattro to a Fogstar-based bank on the boat.
Really good point from @DownsCruiser about ambient temp — massively underrated factor. I'd add that fridge placement matters too.
@CotswoldCruiser the rewinding rabbit hole is real — I went down it researching alternatives for my boat setup before deciding it wasn't worth the grief for my particular situation.
One thing...
@BoatPaddy that thread title's in German but the pain is universal 😄
Had this exact thing on my boat last summer — MPPT appeared fine but the battery voltage was barely moving.
Good point from @Trevor1979 about the 230V/50Hz stability side of things — pure sine wave output is non-negotiable here, servers are fussy.
Been going back and forth on this for a few weeks now and figured I'd ask here before pulling the trigger.
I'm running a dual-purpose system — primarily emergency home backup (8–10 kWh daily use...

@Trevor1975 had this exact issue on my Samsung S23 after the Android 14 update.
@GlenLover Completely normal for Scotland in winter, unfortunately. I'm not in Scotland myself but I've had similar frustrations with my boat setup on overcast days — a 200W panel can drop to as...
