Sma flexible storage system and BackUp
Hello, dear experts! I count on your help in my question.
There is a system:
1. Sunny Island 8.0H12
2. Sunny Boy 5.0-1AV-40
3. Home Manager 2.0
4. Batteries (GEL, 48V, 400AH)
5. ATS (Enwitec) - 1phase, all-phole dissconect
This system is installed and configured itself. Everything works, except for one moment - when the grid disappears (external power grid), ATS isolates my internal grid, the Sunny island inverter supplies its power after 5 seconds. My loads feed farther from the SI. But the Sunny Boy inverter in this mode does not generate. I know that this should not be so and SB5.0 should work in an isolated grid. I made all the settings after studying the manuals from the official SMA website. Country Standart on both inverters - VDE-4105N.
I configured the Linear Gradient on SB5.0 as in the file SI44M-80H-12-BBF-IA-en-10 (page 45)
Sunny Portal is set to "Zero Export".
I ask you to help me. Technical support SMA - no words (((
