Hello everyone,
I have a question about FEMS-box. Is it possible to connect an alternative battery to a Goodwe inverter with FEMS-box, or does it only works with a Fenecon home battery?
Thanks, Kain
Well basically as FEMS is a Product of FENECON and they as a Company sell their Products it is “Out of the Box” “only” compatible with Fenecon Home (also Warranty wise a Problem, if you change or open things [obviously and understandable])
External Inverters can also be measured by FEMS with the Apps FENECON provides - but i guess your Question is better answered by FENECON itself.
