Change the parameters if necessary
Firstly, check whether the fuse on the PV array is OK.
Then check whether the power that is currently allowed to be fed back into the PV array (“#242.14 GnRvTm” parameter) has been exceeded. If this is the case, a “!”. PV array connection is blocked for the set time. Set the “430.02 GnAck” parameter to Ackn.
If the PV array control relay (GnReq) is open, the PV array was started manually (“242.07 GnStrMod” parameter). Change the setting to autostart, if required.
