Anyone else running a Victron MultiPlus on a small shepherds hut setup?

Finally got my 12/3000/120 wired up last weekend in the hut. Paired with 200Ah of Fogstar Drift LiFePO4 and a 400W panel array going through a SmartSolar 100/30. First impressions are decent but I'm getting this weird AC output flicker occasionally when loads drop suddenly — like when the kettle clicks off.

Not sure if it's a PowerAssist thing or just me being paranoid. Checked the VE.Configure settings and honestly half of it goes over my head. Dynamic current limiter is on, shore power limit set to 10A (running off a small Honda genny when solar isn't keeping up).

Anyone seen similar with the MultiPlus on light loads? Worth playing with the UPS function setting or is that a totally different thing?

@DalesCruiser solid setup! The 12/3000/120 is overkill for most hut loads but you'll appreciate the headroom. One thing worth doing early — connect it to VE.Configure and lower the input current limiter if you're running it on a hook-up or genny; the factory default will trip a 16A supply without warning.

Also make sure your Fogstar BMS can talk to the MultiPlus via a VE.Bus BMS or at minimum wire the DVCC settings properly in VictronConnect. Without that handshake the MultiPlus won't respect the BMS charge limits.

Running almost identical kit in my van (100Ah Fogstar Drift, Quattro rather than MultiPlus), and the ESS assistant transformed how the system behaves overnight. Might be worth exploring for a hut with grid/hook-up availability too.

What's your current battery cable gauge? Undersized cables cause more grief than anything else on these units.
