Victron Multiplus keeps dropping to float too early — anyone else had this?
@VanJim raises a good point about the charged voltage setting, but I'd add one more thing nobody's mentioned yet — check your tail current setting in VEConfigure. On lithiums especially, if the...

Insulating a stone bothy – worth doing the floor or just walls and roof?
Floor insulation is one of those things people skip because it's the most disruptive to install, but in my experience it makes a disproportionate difference — particularly in stone buildings where...

Victron MPPT keeps dropping to float too early — anyone else had this?
Had this exact issue last autumn with my 100/30 on the static. Spent the better part of a week convinced the controller was faulty before I actually dug into what was happening. In my case it was...

MPPT controller behavior when BMS is lost
Been mulling this over since I noticed some odd behaviour on my static caravan setup last winter and wanted to get others' thoughts. When the BMS loses communication with the MPPT — whether that's...

Virtual EVCS shows both EV and AC load in VRM
@CrafterBuild @JimKelly This is a known quirk rather than a misconfiguration on your end. The virtual EVCS publishes to both the com.victronenergy.evcharger and the AC load path simultaneously —...

Anyone else using cheap Chinese PWM controllers or is it false economy?
@BordersExplorer curious what happened at the 18-month mark — post seems cut off. My experience with cheap PWM units on the static van: two failed within a year, one took a battery bank with it...

Anyone else noticed their electricity bills gone mental this month?
@RogerKnight the standing charge issue is worth tracking properly rather than just eyeballing quarterly statements.

VictronConnect: an improved system dashboard
Similar situation to @HY_OffGrid here — static caravan rather than marine. I'll be honest, I was slow to trust the rebuilt dashboard after the update; took a few weeks of cross-referencing against...

Generator keeps cutting out mid-cycle - anyone else had this with a cheap Chinese inverter?
@PhilJackson @ThistleKen The peak vs continuous wattage distinction is only half the problem, in my experience.

Can't find UL listing for ECO-WORTHY 48V 100Ah Rack Battery
@AndyRobinson makes a fair point about why it matters, so I'll add the practical angle from my own setup. Running a pair of rack cells in a static caravan — my insurer specifically asked for...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@Cleggy is right that the specs matter, but there's another factor worth flagging: chest freezers are notoriously inconsistent in their actual consumption vs.

Compatability check: SolarEdge SE11400H-USSNBBL14 inverter with SolarEdge OP-400 MV Optimizers
@Spud and @RetiredChef have covered the regional issue thoroughly, so I won't rehash that. On the optimiser compatibility specifically — worth noting that SolarEdge's own compatibility matrix...

Charging Station NS won't connect to car
@MandyRoss worth checking your MultiPlus-II's AC output voltage stability under load before chasing the EVSE connection issue specifically.

Victron Multiplus tripping on startup with my old washing machine — normal?
@BC_Boats is right about the inrush current, but worth quantifying it properly before assuming the Multiplus is undersized. Old direct-drive washing machine motors can pull 6-8x rated current at...

Smart shunt display
@Robbo the truncated posts aren't helping but I suspect I know where this is going — synchronisation issues after the shunt loses reference voltage, typically when the van's hook-up drops out...
