So I've been running a MultiPlus 24/2000 for about eight months now in my off-grid cabin setup — 24V 200Ah lithium bank, 600W of solar on the roof, and it's been rock solid for almost everything. Last week I finally caved and bought a cheap 1800W single-ring induction hob thinking it would be more efficient than the gas, and within about thirty seconds of it running the inverter cuts out on overload. Comes back fine once I reset it, but obviously that's not a workable situation.
The thing is, the hob is rated 1800W and the inverter should handle 2000W continuous with a 4000W surge for about 30 seconds, so on paper it ought to be fine. I've checked the DC wiring and the cable runs look solid — 70mm² from the battery to the inverter, fuses all correct. AC output cable to the hob is maybe 3 metres of 2.5mm twin and earth, which should be more than adequate.
My suspicion is that induction hobs pull a nasty spike on startup or maybe behave oddly enough with a modified sine wave that the MultiPlus doesn't like it — though I thought Victron ran pure sine? Has anyone successfully run an induction hob off a MultiPlus 2000, and if so is there a setting in VEConfigure I should be looking at, like adjusting the overload trip threshold or response time?
