Hi Guys. I have a Quattro 10 000VA connected with Smartsolar 150/85 and SMA Sunny Central 8000 in AC couple mode with 20Kwh of Lithium battery capacity. I am using 12Kwp of solar modules in total. (7260Wp on the SMA and 4950Wp on the 150/85 mppt). When the batteries are completly charged at 12 noon'ish the Quattro shifts the frequency to throttle the SMA production. This works well but each time the batteries are full and the SMA is throttled through shifting the frequency the Quattro switches off in overload and I have to wait a few seconds for the system to restart automatically. What could cause this? How do I remedy it? Each day this happens about 2 - 3 times.
