Hi,
I’m running
- 2x MP II 3000VA on AC-Input => 2 phases of my 3-phase house-installation are covered
- 4x Pylontech US3000
- DC-wiring with 25 qmm and 125A fuse
I think this setup is fairly balanced regarding battery charge/dischage and Inverter/Charger power, which I haven’t limited so far.
Now I’m thinking of buying a 3rd MP II 3000VA to also cover my third AC-phase.
Nominal Inverter/Charger power would then rise to 3x 2400W = 7200W.
My solar panels can provide a maximum of 4500W.
Question:
Is it possible to set a Dischage Current Limit on the batteries so the batteries only add a certain maximum part of power delivery.
I dont’t want the batteries to discharge to fast if there is not enough power from the solar panels. In such a situation where my set DCL would have to be exceeded, the invert should instead decrease it’s power-delivery.
For me, it’s not a solution to limit power-delivery of the inverter itself. Because if the batteries are fully charged, surplus power from the solar panels shoudl completly be feed-in to the grid.
Bye, Alex
