I am curious how you connect a generator to the GVFX? It only has one AC input that us used for the grid.

The client has an existing Generacbackup generator, 8 kW @ 240VAC. From the beginning we told the clientthat the power quality from the Generac may not be within tolerance tointegrate with the grid-tie inverters and charge batteries. Thisassumption was confirmed today when we commissioned and tested thesystem. The output frequency of the Generac was 58 hz. To get to the point does anyone have a battery charger theyrecommend for this application?—8 kW @ 240VAC generator output to 48VDCbattery bank. Or maybe another suggestion to be able to integrate thegenerator into the system, we are also planning on manually transferring thegenerator output to power the critical loads if an inverter goes down. It also seems that the dc genset controls through the matewould be the best way to control the battery charger—any thoughts? Thanks in advance for any input.
