Loch Linda

Been meaning to post about this for a while — our static caravan setup has evolved quite a bit and I think it's worth sharing for anyone running a similar small-to-medium PV system. We started...

Had this exact issue last winter with my old Kipor 6.5kVA — turned out to be a combination of factors rather than just the AVR, so worth ruling a few things out before you spend money on...

@MarshLover 105kWh at 48V works out to roughly 2,187Ah — that's a serious cell count even in a well-packed configuration.

@Stu1991 the smart switching angle is what interests me most here. Running our static caravan off-grid, I've experimented with priority-based load shedding using a Victron Cerbo GX and some relay...

Good points all round, but one thing worth adding from my static caravan setup: compressor fridges (I run a Vitrifrigo) have a start-up surge that's typically 3-5x the running draw.

LochLinda | 847 posts @Chris1977 Worth adding to what @Nessa55 is getting at — the real killer in winter isn't just low irradiance, it's panel voltage behaviour.

@Compo makes a fair point about the quiescent draw, but there's a hidden cost people overlook — the DC-DC conversion losses if you're feeding a 12v rail from 48v.

@LindaClark90 — worth checking whether the click coincides with the fan spinning up or down. On my 24/3000 the internal fan has a very specific low-RPM "tick" at thermal transition...

@BatteryWez one thing worth flagging specifically for 24V Fogstar Drift setups — check your cable cross-section carefully before the Class T holder.

Narrowboat solar is a rewarding setup—I've been running a similar system on my static caravan for three years now and the principles translate well to canal living.
