Venus gx and Marlec Wind Generator

I live off- grid remotely and have recently added the Venus gx to my solar wind set-up. Wind is a small part of the mix but can be important in long full periods. On a recent visit abroad, the batteries dipped enough to cut out the inverter and our freezers!

I see from another thread that ppl have tried using another smart shunt in the wind line, but there appears to be teething issues.

I am thinking of using a current sensing induction relay to detect current in one of the 3 phase conductors from the turbine, wired through an appropriate resistor to one of the Venus tank sensors. https://www.ebay.co.uk/itm/126122619512?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=5ucjjzpttck&sssrc=4429486&ssuid=lzRkCRhsTKK&var=&widget_ver=artemis&media=COPY

The likely readout won't tell me about actual wind output, but it should tell me if the Marlec controller has decided to switch itself off (which it can do from time to time).

I'm a Biologist not an electrical engineer, so any advice would be welcome.

Thanks

the smartshunt is a dc device and thus has to be connected after the rectifier, this would be the best device to use you can measure voltage and current , if you can , of note - its max dc voltage is around 90v so if the wind gen goes open circuit then the voltage maybe greater than that, then you would need a bmv-712 hi voltage unit, again this is DC .
