Hi,
I have a house in Germany where solar panels are allowed in the balcony up to 600-800Watt with very easy installations. I just got 2x400Wp panels with microinverters to be just plugged to a socket in the balcony.
The question is what is the easiest installation I need to add batteries to the system. From the presentation material I found that what is needed a Multiplus connected to the batteries and a meter. I understand the Hoymiles is OK.
I have a 12V 100VA battery from a camper. Which is the first and easier installation? Is the Multiplus 500 or 800 enough (I understand the requirements is to have VE.bus to connect to the meter).
Can I connect the Hoymiles in AC coupling even if it does not support frequency shifting? Can the Multiplus just shut down if the public grid is off in case of frequency shifting not supported by the inverter?
Thanks
Carlos
