Hello folks, I'm running an EMS with two AC coupled 6 kW inverters and four off, 9.5 kWh batteries. Over the last few weeks I have noticed that (on either the app running on Android via cloud servers or a web connection) I lose the house load (goes down to 0 watts) and occasionally the PV generation.
When I pull the detailed logs for the EMS I see that the "calculated load "goes down to 0 at these times.
On one occasion where I could not get any readings for a day, a reboot of all three units brought back communications between them.
I've checked my consumption from the grid and it's running to plan, exactly on my timed charge periods and in reality the system is working perfectly behind the scenes.
I'm thinking that it is a reporting comms problem between EMS and the inverters as my CT are clamps looking good – any thoughts?
