Hello.
I have a problem with the operation of a new wall box (EVCS_Victron) and my grid-connected island system (Multiplus II (48v 3000 W), ESS, Cerbo GX, Pylontech battery (3 x 3.4 kw). 4800 Wp are installed on the carport.
The system is only for charging the EV. (Daily consumption ... drive to work)
I charge from about 15 hours with battery (and if there is still PV power) and grid power. In total, it is about 1/3 grid power and 2/3 PV power for my daily consumption. monophasic. Works in summer as well as last winter, except for a few extreme days.
That means the input power to Multiplus has been limited to 500 W.
My old wall box is defective (after 6 years... Heidelberg ECO) and so I bought an EVCS from Victron to have a suitable wall box.
After the setup (was a bit tricky): After commissioning, I have the following problem, that the Multiplus takes all the necessary energy from the mains.
The Multiplus takes nothing from the battery / PV. See image.
About 1.4 kW comes from the grid and then there is 1.4 kW to AC output and 1.7 kW to WB!?
The wallbox is at AC output 1.
Maybe I've made a conceptual mistake here or a tick needs to be click somewhere...
