AC Frequency shift for ECCO inverter off grid
Setup advice - offgrid.
Is there a linear frequency shift function on battery SOC (or voltage) for the backup AC output ?
Where... the output of other AC connected PV inverters connected on the backup output of the ECCO hybrid could reduce their output, as the battery approaches fully charged.

Hi Chris,
PV inverters needs to connect to the Aux port. (Marked as GEN). the limit for grid tie inverter to be used on this port is 50% of the inverters rating. so, for 8Kw it would be 4KW grid tie. then in off grid mode the Sunsynk will use frequency shift to control the power of the grid tie inverter. Then when utility is connected to Sunsynk the Sunsynk will switch on/off for grid tie for it then cannot change the utility frequency.
