Have a problem with a multiplus II on start up with frequency, if there is solar capacity and grid drops out with charged batteries the ac output shuts down, which is understandable no where for power to go. But when it restarts it starts with frequency at 49.99HZ, which means that solar will start up at full capacity again and with no were for power to go (if no load) then ac cuts out again this will happen sometimes, but sometimes the multi will start with frequency @ 50.5HZ (this would vary on systems depending on what solar inverter is set to) and when it restarts in this way there is no issue with the solar starting off at low power output and the system does not drop out.
Is there a way to make the multiplus start at a higher frequency, this would allow solar to start off at a low capacity and build up, instead of dropping power out and back in, until it can settle itself down. It seems to me that the ac coupling on the victron is a real challenge from what I have read.
Any ideas?
