Hi,
We have a mppt control and a mppt 150/60. Today we reconnected the solar panels after having worked on the boat for 8 months and thus also no solar panels connected and the mppt deconnected.
The mppt seems to be working fine as I can see on the amps in, on the battery monitor (bmv 702).
However the mppt control only displays a scroling disconnected. Before we disconnected everything all was working fine....
Any ideas what this could be?
