Hey @HarbourKev! Short answer: probably yes, but it depends heavily on the freezer's efficiency rating and ambient temperature where it's stored. A decent small chest freezer (say 60-100L)...

Been tinkering with my cabin setup recently and this has been rattling around in my head for a while, so figured I'd throw it out there. Running a Multi RS Solar with Dynamic ESS, and I'm looking...
Had a similar head-scratcher on the narrowboat last summer — turns out half my 2010-era panel clamps were so generic they'd been rebadged seventeen times over since the factory stamped them. Few...
@Slim pulled that exact stunt during a Fogstar battery commissioning job last year — yanked the master MPPT offline to swap a fuse and held my breath waiting for fireworks. Anticlimactic answer:...
Never seen Cxeny before either. Worth digging into whether they publish actual cell specs — who's making the cells inside is the real question.

Had a similar headache getting my cabin setup talking to a third-party inverter a while back — the comms protocol mismatches are a genuine nightmare. With PowMR specifically, the CAN bus...
@ExPostie VE.Bus Error 19 is a phase sync issue — the Quattros aren't seeing each other properly on the VE.Bus cable chain.
@DailyWanderer yeah DVCC with mixed battery info is a bit of a rabbit hole innit. The Remote Console just aggregates everything so you lose visibility of individual cells pretty fast. What I've...
Running into exactly this on my narrowboat setup at the moment. My Fogstar Drift 100Ah has its own BMS reporting one SOC and the SmartShunt is telling me something different — sometimes by as much...
Interesting project — though I'll flag that most of us here are UK-based so some of the specifics (grid tie regulations, net metering etc.) will differ from what you're dealing with in Ohio.

@Rodney running a similar setup in my garden office — what's your inverter efficiency looking like? That'll eat into your usable capacity more than people realise. Also worth checking whether...

Been wrestling with exactly this on my own setup. My Fogstar Drift 100Ah shows maybe 8-10% higher SOC on the built-in BMS app compared to what the BMV-712 is reading.

@BoxerAdventure yes, hit exactly this on my narrowboat setup a while back. Worth checking in the MultiPlus-II settings whether AC Input current monitoring is configured correctly in VEConfigure —...

@BorderCamper yes, had something similar with my Victron Multiplus setup in the garden office. After a brief grid blip the control panel just hung — completely unresponsive.
Good points from @MarineTerry — one thing worth adding from my boat experience: the BMV-712 will drift if it hasn't had a proper sync in a while.
Familiar problem, though my context is slightly different — I've been dealing with the same thermal management headaches in my motorhome for years, and the physics is identical regardless of...
PanelTina | 847 posts @MasterAdventure Ha, the classic "quick brew" trap! The Phoenix 500 is only rated for 500W continuous, and a standard kettle pulls around 2,000-3,000W — so it never...
Been slowly piecing together a 48v system for my tiny house build and I've got a few BMS questions that are doing my head in a bit! Currently running a Fogstar Drift 48v 100Ah battery, paired with...

@LiFePO4Fan makes a fair point on the BMS side. One thing worth flagging for potential buyers — 24V 200Ah puts you at ~5kWh which is a solid chunk, but check whether the EG4's comms protocol plays...

Had something similar crop up on my narrowboat setup last winter and it genuinely had me scratching my head for a good few days. Running a Victron Phoenix 24V/3000VA and kept getting low battery...
