Sean Genetry Solar Posted May 19, 2021 Share Posted May 19, 2021 This thread is for all the details of our new 'Split Sync' mode that we offer on all our GS inverters. This topic will be updated by myself and Sid with all relevant info pertaining this new mode. In basic terms, the Split Sync mode allows you to run 2 inverters together that will share the load of a 240V service panel. It is similar to daisy chain but is a preferred method when running just 2 inverters. It allows you to double your surge and load capabilities assuming you have a well balanced service panel. Each inverter acts like a Single L coming into the panel and they operate 180 degrees out of phase from each other. There is a downside to this mode. If you have purchased a GS inverter you will need to send it in (or do yourself by breaking warranty) because the inverter needs to be rewired for 120V regardless of if you chose to have 120v inputs. If your plan is to run in split mode and you have not purchased an inverter then it can be setup here. Another Downside is you can only run with 2 inverters. So if you plan to have 3 or more inverters then this mode would not work for you and daisy mode would be the only option. The picture below shows 2 inverters setup for Split Sync mode. S = Slave Inverter (Inverter must be set to "Split Sync Slave" in the LCD) M = Master Inverter (Set as Normal) N = Neutral E = Signal Patch L1 = Line 1 L2 = Line 2 NN + NN are tied together between the 2 units. E + E are tied together between the 2 units. M L1 + S E L2 + L2 are NOT tied between the 2 units but rather tied together at the inverter to give full output L1 + L1 are NOT tied between the 2 units but rather tied together at the inverter to give full output N + N are tied together between the 2 units. Your L1, L2, N would lead to the breaker panel in much the same way a 240V Split phase inverter would. Quote Link to comment Share on other sites More sharing options...
