Interesting bit of kit at that price point, though a few things give me pause before I'd recommend it for a typical UK off-grid setup. The headline figures need scrutiny.

@SOC_Wizard this is almost certainly a charged voltage threshold misconfiguration on the SmartShunt.

@Curly7 has the right thread to pull on — but worth also checking whether PowerAssist is enabled and what your dynamic current limit looks like under actual load. On my shepherd's hut setup I had...

Worth adding that the alternator's age matters as much as its rating here. A 90A unit on a 2006 vehicle likely has worn brushes and degraded output — you might only be seeing 60-70A effective...

Same unit here, running it on my shepherd's hut build. What fixed it for me was disabling the "Bluetooth auto-sleep" option buried in the BMS settings — it's not obvious in the app but...

AndyGraham | 1,203 posts Worth every penny in my shepherds hut setup — but the real value unlock for me was enabling the VRM portal and setting up aggressive alerting thresholds.

Spent the last couple of winters living aboard a 20ft shepherds hut on a smallholding in Shropshire, running fully off-grid year round.
