Response time of Multiplus Frequency Control with "PV inverter support" too fast

Is there anyway in reducing the response time of the Multiplus when it increases the frequency in order to reduce the charging current with the PV Inverter Support Assistant? The problem is, that the Multiplus jumps to the set maximum frequency to reduce the output power of the Solar String inverters. This causes the String inverters to overthrottle the output. The system eventually stabilises after 30 seconds.

Any idea?

You can move it in stages ie 51hz then 52 then 53


This will allow partial throttling if the PV inverters you have will allow it that is

ie 25% 50% then 75% then full off

It has to be quite quick as at the stage of throttling the battey voltage is increasing or the grid is being feed back power

I dont know if that will be of help
