I have a Multiplus II GX system which is installed with the ESS application. It's connected to the UK grid via a single phase 100A supply, connected to AC IN of the Multiplus.
All loads and an AC coupled solar inverter are also connected to AC IN of the Multiplus.
The Multiplus is able to balance the grid supply close to zero, charging the batteries off of solar and discharging them as required. I also have time of use tariff which enables the Multiplus to charge the batteries over night.
The issue I have is that I run a lot of loads over night in the cheap period of my tariff including a 32A electric car charger. This regularly take my load over 50A.
The Multiplus needlessly regulates its own charger down in this period and on occasion supplements my grid supply from batteries. This is needless and results in me not having a full battery bank at the end of the cheap time-of-use period.
I can't increase the current limit beyond 50A on the Multiplus or seem to disable it. It is not needed in a parallel grid connection as I have it, as far as I can see.
Can somebody advise me as to whether I have missed a setting or if this is something Victron need to consider in a future firmware update. I want to be able to heat my water, charge my car, batter bank, run my dish and clothes washers during my off peak period!
