Any idea why Fronius is restricting its output when the grid is missing even when soc is less than 90 %?
did I miss some setting?
with grid available, it produces on average 700 to 1200 watt to match my house load
Screenshots attached
checked following
1. Quattro frequency - exact 50.0 Hz
2. ESS debug menu - I charge = 140 amp. P charge limit = -1.0
3. PV input voltage present at Fronius terminal above V start almost 300 V
