Hi Everyone,
I've been running my Grid-Parallel ESS (Split-Phase) for about 6 months now and things were going well, but because I did not have a Grid Meter, it wouldn't count consumption or grid-feed-in properly.
Two weeks ago I installed an EM530 and it's working well showing consumption, but I've ran into a problem where the system is not stable unless I control it manually. Here are the issues:
- When PV production is higher than consumption, it won't inject into the grid unless I set the mode to "external control" or Pass-through.
- When PV production is higher than consumption, it will overcharge my battery and go into High DC-Voltage Alarm, unless I set the mode to "external control" or Pass-through.
- I've had to create a bunch of manual settings with Node-RED so the system half-works as I want.
Any help would be greatly appreciated...I'm at a loss manually controlling my system daily...
Here's how my system is configured:
