Figure 1-20 Sync Connection for Split-Phase
AC coupled energy sources can be connected either to the Master and/or Slave Sunny Island
4248U (L1-N, L2-N, 120 V) or to both outer conductors (L1-L2, 240 V).
Once the wiring is complete, the units must be set for split-phase operation.
• Power up the Master inverter and go to parameter 41-5, “Splitphase” and set it for Mas-
ter. Power down the master inverter.
• Power up the Slave inverter and set the same parameter for Slave. Power down the slave
inverter. (You may now disconnect the battery temperature sensor cable from the slave
inverter.)
Now, when the inverters are restarted, they will operate in split-phase configuration.
