Hello everyone,
I have not been able to find the answer anywhere online regarding the Fronius Ohmpilot and I'm not sure if this community would have the answer either. I hope so though!
I am looking at including a Fronius Ohmpilot at the AC out of our Multiplus II to utilise excess solar PV for electric hot water heating in a storage tank. I would also like to include an external hot water heater that would heat up the water when there isn't sufficient excess solar. The Ohmpilot can easily integrate both through a nice relay function, enabling the external heating source to start up when needed. A Fronius Primo is currently also connected to the AC out. The Fronius Primo keeps charging the batteries when the grid goes down.
The Ohmpilot requires a Fronius smart meter to function (I believe). What would happen if the grid goes down and the smart meter stops functioning? Would any excess power not be utilised by the Ohmpilot and would the relay also not function meaning the external heating source would not fire up to heat the water?
Keen to hear your thoughts!
