Hi All
I hope I can get some clarity. I have yet to implement an ET112 meter. I would like to add an MPPT and PV modules to a system that is currently installed as a UPS.
Multiplus ii 5kVA, SolarMD 7.4kWh lithium battery, Cerbo GX ect. AC-Out 1 is used to supply Critical loads. All lights and certain plug sockets for WiFi and TV. AC-IN is fed from AC mains.
My question is this : I want surplus PV energy to supply loads on the input side of the Multi. So I should install the ET112 between the main MCB and the Multi. I am familiar with the wiring and settings on the Cerbo.
I am however uncertain how this will be displayed in VRM? I do not wish to feed the energy into the grid as there is a prepaid meter installed. I only want the surplus energy to supply the larger loads on AC IN.
Combined loads may exceed 5kVA on the input.
The other option is to rather use a PV inverter on the input side.
Any suggestions, advise would be appreciated.
Thank you
