Series Stack (OutBack)
Up to 10 inverters or other devices; requires balancing transformer
Master inverter and half of the Slave inverters use common output AC bus (L1)
The remaining Slave inverters use a separate common AC bus (L2)
Master inverter is always active; regulates output based on load;
can power both L1 and L2 buses using balancing transformer
Slave inverters remain in Power Save mode; Master activates
any Slave inverters for either L1 or L2 based on load
Series Stack (Classic)
2 inverters; up to 8 other devices
Master and single Slave inverter use separate output AC buses
(L1 and L2)
Both inverters always active
(no Power Save mode);
outputs are loaded independently
but output regulation is controlled
by load on Master
