How to adjust behaviour of ABB PV inverter on MultiPlus AC-out1?

hoi,


Is there something ( a way ) that the PV-inverter (AC-outA1) has prior instead of the DC MPPTS ?


what i mean is :


My ABB pv-inverter goes off and back on several times on a day when my battery is full and there is to much solar to feed it back to the grid (now on 19A limit)

i have 4000w PV-inverter on the AC-output and (for now) 4000wp on the DC side...

and ofcourse thats to much solar power when the battery is full. (or almost full)


so that the PV inverter (AC-out1) can go full power and the DC mppts go in limit?

because the freq. shifting is not going so good i think.. :(


grtz kristof


P.S.

ABB is connected via zigbee (no RJ45 possible)

now i gone test the last "beta v2.30-43" , but i read the description and didnt see thats in it ..

Maybe try and change the derating settings on the ABB and play around with it a bit until you are happy with it. Decrease the ramp time a bit.

That is where your problem is. You need to get n PVI-USB RS485 converter from your ABB distributor. Then you need to get Aurora manager TL and also a service password. The Frequency shift settings are done on the ABB using these tools.
