@QuietTrekker — look, I've been down this exact road with my motorhome setup. Started with a cheapo PWM controller and the regret was real. Here's the thing: on a 2kW system, you're looking at...
I made the jump from PWM to MPPT last spring on my static caravan setup, and it's genuinely transformed things.

Right, here's the thing — I've mucked about with one of these in my garden office setup and it can work, but you've got to be methodical about it. The manual being sparse isn't the real problem.
Right, I've got a Flexboss21 on my narrowboat paired with a cheaper string inverter (not Solaredge, mind you) and the AC coupling side is... let's say temperamental.

Right, I've had this dance with my van setup. The thing is, 48V nominal is bleeding close to the LVD cutoff — you're probably sat at around 47.5V under load before it trips, yeah? Worth checking:...

The 5K sits in an awkward middle ground, honestly. You're paying considerably more than a 3K unit (where @BoxerWanderer's had decent longevity), but you're not getting the build quality or...
Got 400W on my shepherd's hut setup (essentially stationary, mind you) paired with 200Ah LiFePO4, so I'm in that ballpark with @FormerMariner1.
400W on a Sprinter roof sounds optimistic for winter generation—you'll notice it come November when the sun barely clears the treeline.

The real question is whether you've got the battery bank to back it up — I learned that the hard way with my garden office setup.
I've got one of these paired with a Victron MultiPlus in my static caravan setup, and I'm genuinely impressed with the build quality for the price point.

Look, I've been down this road with budget gear on my boat. The real issue with Eco-Worthy isn't necessarily the inverter itself — it's that when something goes wrong, you're left hanging.

Had the same grief with my static caravan setup. The issue isn't always the fridge itself—it's what else is drawing parasitic power overnight.
@FormerMariner1 and @VanKev, that's a decent sweet spot you've both hit. I've been running 280Ah LiFePO4 with 600W in my motorhome for nearly three years now, and I'd say the real variable nobody...
Worth adding to @Spud's point — check the actual voltage at the Multiplus terminals, not just at the battery. Cable resistance can be deceptive.
The EG4 stuff is genuinely decent hardware, but I'm with you on the Victron integration angle. I've been running Victron across my motorhome setup for three years now—the way their chargers,...

The voltage sag is precisely the issue @GrumpyWarden. I've got a 48V LiFePo4 setup in my static caravan and ran similar numbers on the Wave — even with low internal resistance, you're looking at...

@Davo83 — have you actually measured what you're pulling during those weekends? That's where most people go wrong.

I've been there with my narrowboat setup! The thing is, 48V is actually quite a tight margin if your battery management isn't spot on.
Have you checked your browser's reader mode? Works a treat on mobile—most phones have it built in now.

ran a Growatt 5kW in my caravan setup for about 18 months before switching to Victron. Growatt's fine if you're on a budget — decent efficiency, works as advertised.
