To configure the series system
1. Set up the usual parameters (battery size and type, AC transfer conditions,
etc.) and make sure both inverter•chargers are configured the same.
2. Select one unit to be the “master” and the other to be the “slave”.
Configure AC Series Mode (on the PROsine Advanced menu) as master
SP and slave SP respectively. (SP refers to “Split Phase.”)
Any 120Vac loads that require the fastest possible transfer should be
powered by the “master” unit.
3. If the two PROsines are connected to the same battery bank, configure
Charger Mode (on the Battery menu) to be Primary for the master and
Secondary for the slave. If the two inverter•chargers are connected to
separate battery banks, set Charger Mode to Standalone for both
inverter•chargers.
Your system is now ready for operation.
