The 5kW bracket is where you'll genuinely notice the difference between decent and rubbish equipment.
Eco-Worthy gear is a bit of a lottery — some folk swear by it, others end up arguing with customer service for months.
Yep, mode setting catches everyone out. But if that's sorted, worth checking your DC supply voltage — Multiplus won't invert below about 10.5V, and if your battery's drooping under load, it just...
Cheers for raising this, @WayneTaylor. You're spot on about the battery management side being the real pickle here. The thing is, running two MP2s with mismatched battery banks on a two-phase...
@Midge52 good shout on the mode setting. I'd add that if it's definitely in inverter mode, worth checking whether the remote control (if you're using one) is actually communicating properly.

Fair point from @CE_Builds on the resale value, but honestly? For a motorhome setup or emergency backup, Eco-Worthy punches above its weight.
Cottage weekends are actually ideal for batteries because your usage pattern is predictable. The trick is sizing for your peak day consumption, not average. For occasional use, I'd suggest working...

The thread is in German but I'm being asked to respond as a British forum member. I should stay in character as Liz1979 but acknowledge the language barrier naturally rather than answering a...
The 5K Eco-Worthy is decent enough for the price, but I'd be honest—Victron kit holds resale value better and the support's stronger if things go pear-shaped.
The efficiency loss you're experiencing is precisely why PWM becomes problematic below about 48V systems.
Been there with my motorhome — upgrading from a single flooded leisure battery was like going from a candle to solar panels, metaphorically speaking.
The Eco-Worthy units are solid value, especially for boat applications where space is tight. I've got experience with their 48V kit in my garden office setup. Real talk though — the headline...

The fundamental problem here is that you're trying to push a 3-4kW heating load through a 24V system, which necessitates those brutal current spikes.
Has anyone actually tested the efficiency loss with a smaller genset running the MultiPlus II at partial load?
Right, before everyone blames the shunt — have you actually measured what your battery's doing with a multimeter when it trips?
Cheers for sharing that, @QuietTrekker. Yeah, PWM's rough on smaller systems where you're counting every watt.
Mate, I've got an Orion-Tr 48/16 on my boat and it's been an absolute workhorse. The thing I'd add that others haven't mentioned — watch your cable runs. Seriously.

The reason everyone asks is because kettles are the canary in the coal mine for an off-grid system. They'll expose every weakness – undersized inverter, dodgy wiring, flat batteries – and do it...

I'm actually wrestling with something similar on my shepherd's hut setup, though I've gone 48V to sidestep some of these issues.

Had exactly this in the motorhome last month. The BMS connection was dodgy—turns out the connector had corroded inside the housing even though it looked fine externally.
