Hi,
I have an MP2 48/5000 with inverter on the input (EM24 is on the way...). Also 4x12 V batteries on SmartShunt setup. The ESS is a 'self-consumption' system.
I've added a SmartSolar 250/70 and connected 2 panels of 375 Wp each. I cannot get the SmartSolar to work. It say 'charging' and 'External control' but only 2 Watt is displayed:
The panels are 78 V and the batteries 51.5 V, so +5 V is met.
Can anyone confirm this not to work? DC feed-in is enabled and the solar power should also be used to power the loads.
Another thing is the SmartSolar is second hand, so maybe it is just broken. How to test that in an easy way?
Kind regards and thanks for any help.
Ralph.
