Dear everybody,
I setup an ESS system with 2 x Multiplus II 3000 (1 master, 1 slave) on 1 phase. Each Multiplus run with the 453 FW. The system is connected to a load (a house), a grid network and a 16kWh 48V battery pack.
In case of no load (general house breaker OFF) and no chargind activity, my external grid power meter see an important reactive current : 250VA vs 20Weff.
The defference decreases as the load increase and is quasi null for a global load around 2/3000W. I don't remenber seeing this with the same setup with only 1 Multiplus.
Is it normal to have this reactive current on grid when coupling 2 Multiplus II ?
Thanks for you comment and have an happy new year.
