PB
The PV (-) and BAT (-) terminals are connected internally. Only one negative wire may be needed to
connect to the (-) wire lugs if the PV - and BAT- conductors are bonded at the negative bus bar. See
Figures 2 and 3 for sample wiring diagrams. See Wire and Disconnect Sizing on page 80 for suitable
conductor/wire sizing.
NOTES:
•
Each FLEXmax 80 requires its own PV array. DO NOT PARALLEL FLEXmax 80 PV+ and PV- TERMINALS
ON THE SAME ARRAY!
• An optional battery Remote Temperature Sensor (RTS) is recommended for accurate battery
recharging (only one RTS is needed for multiple OutBack Series Inverter/Chargers and FLEXmax 80
units when an OutBack HUB and a MATE are parts of the system). When one RTS is used, it must be
connected to the component plugged into the Port 1 of the HUB.
