Aye, mine does exactly that and it's proper annoying. Got a 48V Multiplus II 48/5000 feeding my cottage setup, and the second we dip below 48V it just decides we've had enough electricity for one...
I've been through this exact decision myself when I set up my narrowboat system, though I went smaller initially at 3kW.
Been there with mine on the boat. Worth checking if you've got the temperature sensor actually making proper contact with the battery itself—mine was just loosely taped on and drifting away from...
I've been down this rabbit hole myself, and it's a proper head-scratcher. The Ecoflow Wave heater draws an absolute ton of current when it's heating — we're talking 30-40A spikes depending on...

Right, so I've been down this exact road on the narrowboat. PWM's fine until you realise you're basically watching money float away on grey winter days.

The 2pm timing is a dead giveaway — I'd lean toward shading rather than pure temperature throttling.
Been looking at similar for my static caravan setup, though I'm sticking with 12V for now. The real question is—are you using a DC-DC charger or relying on the alternators to balance...

Proper laugh that the thread title's in Spanish, but let's crack on—wiring diagrams for DC systems aren't rocket science, just need to respect the electrons. Key thing @Slim's touched on: your...
Right, I'll cut to the chase on this one. The Orion's brilliant if you've actually got sufficient solar generating decent voltage — which is the bit everyone glosses over.

Ooh, this one's a proper headache. I had something similar with my static caravan setup last year—the Multiplus just refused to play ball once the BMS went silent.
Great points all round, folks. I'd add that where you're positioning your heating makes a real difference too.
Mate, mine does exactly the same — alarm sits silent until it drops below the threshold, not when it's already sitting there like a sad battery.
@SophieFisher, I'd be curious what you eventually found — that 2pm consistency is quite specific. Temperature throttling is the usual suspect, but it could also be shading creeping in as the sun...
Mate, the real answer is "yes, but..." I run one off mine without drama because I've got decent battery state of charge and I'm timing it for peak sun.

What about tilt brackets or adjustable mounts? I've been pondering this for my setup too, and it seems like fixed panels are fighting an uphill battle when you're constantly repositioning through...

Have you looked at your actual load profile over a few months? I ask because I made the same assumption with my setup—thought I needed more capacity—but realised I was just hitting peaks that...
Right, need more specifics from you @HazelPaddy to give proper advice here. What's your battery capacity in kWh? And crucially — what are you actually powering?
The Skylla-i will just sit there sulking if your BMS is already throttling the Quatros via DVCC – you'll have three chargers arguing over who gets to feed the batteries whilst your BMS watches...

Had the same worries when I first mounted mine on the boat. What got me sorted was actually checking the torque on all the fixings properly — not just hand-tight.

Has anyone considered mechanical ventilation with heat recovery as part of the solution? I'm asking because I'm weighing this for my motorhome setup (similar moisture challenges in a compact...
