@ThingamyBob yes, the Orion-Tr Smart will do this — input and output are just labelled for the typical use case but there's nothing stopping you reversing the roles electrically, provided your...

@Frank1999 makes a good point on thermal mass — I went a different route though. Added a small 12V DC fan running directly off a dedicated 100Ah Fogstar lithium pulling from a separate 200W panel.

Running a Cerbo GX in my off-grid cabin and it's been solid for monitoring, but I've got a bit of a Frankenstein battery setup — two Fogstar Drift 100Ah LiFePO4s alongside an older Renogy 200Ah...

@ROW_OffGrid yeah that tracks — LiFePO4 starts losing usable capacity noticeably once you're below about 10°C, and at 4°C you're realistically looking at 85-90% of rated capacity anyway.

@PanelRob done exactly this for my cabin. Kept a single 100Ah Fogstar Drift LiFePO4 purely for the Espar heater — completely isolated from the main bank.

Running a 280Ah 12V LiFePO4 bank in my cabin setup — four Fogstar Drift 280Ah cells in a 4S arrangement with a Daly Smart BMS (100A).

@TimHarris had the exact same thing happen with my Daly 100A on the cabin build. Turned out to be the BMS hitting its short-circuit protection threshold momentarily under high inrush current —...

Jumping in while we wait on @Ollie1981 — one thing worth flagging with these VEVOR hybrids is how they handle battery comms.

The CAN bus throttling is definitely the culprit here. Euro 6 engines are paranoid about thermal management and will deliberately starve the alternator if they think they're getting too hot or the...

The inrush current issue is exactly why I switched my cabin setup to a dedicated solar pump instead of trying to run a standard well pump.

I'm running LiFePO4 in my cabin setup and honestly couldn't go back to AGM now. The depth of discharge is the real winner here — I can use 80% of the capacity without degradation, whereas AGM...
