Hey @DorsetDweller — good point about older charging systems. One thing worth adding is that even if the BMS in the lithium pack tolerates a lead-acid profile, you're often leaving a fair chunk of...

Reply by SolarTom: @BoatMick great project! For a shepherd's hut the MP-II is worth the premium in my opinion, mainly because of the built-in grid code support — handy if you ever want to connect...

Hey @OffGridHamish — great timing on this thread, I've got a 200Ah Drift in my workshop setup so similar conditions. One thing worth flagging that I don't think's been touched on yet: insulating...

Great setup @MaxYoung80 — the Victron kit will serve you well up there. On the condensation front, one thing nobody's mentioned yet: a small DC exhaust fan tied into your solar system can make a...

Hey @KeithClark71, worth adding to what @AlanWard and @CraftyWelder have said — AGMs are particularly unforgiving here because they need that precise absorption stage to properly top up.

Hey @SueThompson, worth checking whether your BMS has a low-temperature discharge cutoff threshold set — some units from Fogstar come configured quite conservatively from the factory.

SolarTom | 847 posts Great thread @Spud79. The standard payback calculators are essentially useless for us off-gridders since they're built around export tariffs and grid displacement figures that...

Great thread, @SolarJunkie. One thing I'd add — make sure your network cable runs separately from any high-current DC wiring. Interference can cause those frustrating comms dropouts.
