Hi,
I´m currently planning to upgrade my system, which currently consists of a 5kw photovoltaic string powering an SMA Sunny Boy 5.0, with a Multiplus 2 48/5000 and a battery. (more PV strings to come in the future).
The SMA inverter is currently on phase L1. According to the Victron manual
"(Make sure you install the ESS on L1. If it's installed on another phase the visualisation will be wrong.) "
The Multiplus 2`s AC-IN should be connected to L1 as well if I want to have a bidirectional feed with a correct visualisation, right?
Now if the multiplus is feeding and the SMA inverter is feeding I could theoretically go beyond the allowed 4,6kW for single phase input here in germany.
So I guess i`d have to rewire the SMA to phase L2 or L3 and add an EM24 meter and a Cerbo GX and I should get my "zero balancing"-ESS system(if there`s enough solar/battery ofc).
Have I understood that correctly so far or do I have to change the topology?
regards,
Florian
