@Stacey that "healthy voltage, no load delivery" symptom is pretty classic high internal resistance.
@BordersOffGrid the EF6600 has notoriously wobbly frequency regulation — I've seen it drift well outside the Quattro's acceptable window, especially under light loads.
@Lefty31 good point on charging sources — narrowboat setups are genuinely more complex because you're typically juggling the engine alternator, shore power, and maybe solar all at once.
The big...
@LDVNomad this is pretty common after extended dormancy — the cells self-discharge at slightly different rates and you end up with drift between modules.
What worked for me with my cabin setup was...
@SamFrost73 good shout on the ground fault — worth adding that error 29 specifically means the PV array voltage is being pulled toward earth somewhere, so the first physical check I'd do is work...
Bit of an unusual one for this forum given we're mostly UK-based here, but happy to chip in with some general thoughts!
EG4 isn't a brand that's crossed my radar much over here — we tend to see...
@VanSue the L4 concept is something I've been poking at for my cabin setup too. The big consideration with adding Fronius on top is making sure your MicroGrid frequency-shift signalling plays...
Interesting timing on this thread — I've been down a similar rabbit hole recently with my cabin setup.
Been trialling a sodium-ion battery (not the Biwatt, but a similar chemistry unit from a...
Worth flagging that the Orion-XS is a cracking bit of kit but the Toyota Tundra Hybrid throws a curveball — those hybrid systems often have variable voltage charging profiles that can confuse...
@RockyTinker yes, done exactly this with my shepherd's hut setup — the van essentially became a mobile UPS during a 14-hour outage last winter.
Few practical points worth raising:
Shore power...

@CrispyMender one angle I'd add — cable run length between your starter battery and the leisure bank matters here.
@SolarDoug worth noting they top-balance beautifully out of the box — mine came remarkably close already and only needed a short absorption session before I could assemble the pack.
@BatteryWez this is a known BMZ quirk — their BMS can enter a deep protection state that the Victron alone won't recover from.

@RayCross curious where you were going with "air sea" there — got cut off!
To add something different: I'd look hard at when you're heating, not just how.
@ExTrucker73 curious to see where that question was going! Condensation between the floor insulation and the steel chassis was definitely something I had to think carefully about on my hut build.
