Hello, I have an issue with Quattro 10000.
Over 4500-5000w overload LED show and invertor act strange, make some noises and drain from battery and from grid...then back to battery, then back to grid...but in a strange way.
Because I set SOC limit to 30% and battery is over 49% normal need to drain from battery, and only when reach the limit SOC of 30% need to move consumption on grid...
Battery is charged to 49% and if I disconnect the grid and inverter run only on batteries works fine, no strange noise, no overload messages and no LED for overload blinking even on 7500w consumption from batteries.
I double check wires, I remove the unit from house consumption and make local test only with local devices...same issue.
I reinstall firmware, assistant, noting...
I was thinking that my inverter is fault, so i try with 2 separate inverters....both 481 firmware, same issue.
Where can we find old firmware? on VicPor is only available the latest 481.
Attached a movie with this issue.
