@DownsWanderer the AC load figure in VRM is calculated, not directly measured — it's essentially grid input + inverter output - known loads.
@WD40Wizard11 120mV is significant but not necessarily a death sentence — depends on the cells.
Few things worth checking:
Is your Victron absorption voltage actually high enough to trigger...
@CamperClive the price is right but secondhand panels are a proper lottery. Main thing I'd check is whether it's got microcracks — lay it flat and look for hotspots with a thermal camera if you...
Seen something similar crop up with my Victron MPPT — not the same model but worth chucking in here.
Had a stretch last summer where my 48V system was sitting rock solid at 52.2V across everything...
Yeah, seen this with Pylontechs before. The BMS goes into a sort of hibernation state during long storage and loses track of cell states — classic after a winter sitting idle.
Few things worth...
Been down this rabbit hole myself recently. Got a Multi RS Solar paired with a Cerbo GX and I've been trying to get proper grid setpoint control working through Home Assistant via Modbus TCP.
The...
@PanelKate exactly, and that's before you factor in shipping costs from Indiana plus import duty + VAT.
Been there with this exact headache on my own boat. Nine times out of ten it's the BMS doing its job — lithium doesn't sag like lead acid, so it cuts hard when it hits a current limit rather than...
@MidlandsSolar what strings are you planning to run into it? The 450V max input is the key thing to design around — you can series up panels to hit decent voltage without going over.
Solid thread — been doing similar with my setup, trying to optimise panel placement around a mast shadow that moves annoyingly throughout the day.
One workaround worth trying: most phones can log...
Good points from @BoatJason and @BoatPaddy already.
One thing I'd add — check your battery voltage sense setup.
Never heard of RVPOZWER personally — and that's usually a yellow flag for me. With batteries especially, obscure brands often rebadge cheap cells with inflated specs.
@WattKaren and @SparkySparky...
@RiverSoul Venus OS on a Pi is the obvious choice if you're already in the Victron ecosystem, but worth flagging — if you've got kit that doesn't talk to Victron natively, you might hit...
Tried something similar feeding a Victron MultiPlus into a micro inverter chain — it's a rabbit hole.
Main thing I'd flag: grid-forming vs grid-following.
Depends heavily on ambient temp and how full it is. A full freezer holds cold much better than an empty one — if yours is half empty, chuck some bottles of water in.
Rough numbers from my own...
