Hi I thought I d try out grid tie inverter on our standalone system, but I can’t find the reduction freq or minimum freq for sunny boy sb2500? The only freq I can find on spec is 49.8-50.02
Any ideas? I don’t want to load assistant with wrong data! Cheers
even if you do load the assistant you can change the setting latter.
the frequency shift settings are in the sunny boy so you will need to contact them.
or try 50.5Hz 51Hz and 54Hz that should cover the range IF ITS SETUP in the sunny boy.that is
you will need to test this very carefully to make sure that the sunny boy responds.
NOTE the victron inverters can ONLY Freq Shit up if the mains are OFF
Great thanks for getting back, sma weren’t very helpful but the shut off is at 50.2hz. So at 54 it would have shut off well before?
As for mains off do you mean the ac in which isn’t connected as we don’t have anyway, or do you mean no draw on the outlet side?
Many thanks matt
Mains off on ac1 in
normally most of the Grid tie inverters can have there shut offs changed so you can derate by 50% ot 50.2 then 75% at 52 and full shut off at say 53h
these are just examples to give you a full idea
if yours shuts off at 50.2 thats also fine just make sure it does do that, you just dont get the advantage of using a de rating and thus not loosing all the solar in one hit, thats all
