Introduction
IMPORTANT:
This manual provides safety guidelines and installation information for the
FLEXmax Series Charge Controllers. It does not provide information about
specific brands of PV modules and supplies limited information on batteries.
Contact the supplier or manufacturer of the PV modules or batteries for
additional information.
Thank you for purchasing a FLEXmax Series Charge Controller (CC). These
charge controllers offer an
efficient, safe, multi-stage recharging process that prolongs battery life and assures peak performance
from a PV array.
Each charge controller is designed to seamlessly integrate with other OutBack components and can
be remotely monitored and configured (up to 1000 feet or 300 meters away) using the optional
OutBack Power Technologies system displays.
Features
The FLEXmax Charge Controllers use continuous Maximum Power Point Tracking (MPPT), which seeks
out the maximum power available from a PV array and uses it to recharge the batteries. Without this
feature, the PV array does not operate at the ideal voltage and can only operate at the level of the
battery voltage itself. (See page 95 for a description of MPPT.) Each charge controller continuously
tracks the array’s maximum operating power.
The FLEXmax Series has two models available:
FLEXmax 80: 80 amps maximum continuous output current (up to 40°C without thermal derating)
FLEXmax 60: 60 amps maximum continuous output current (up to 40°C without thermal derating)
Both models have the following features:
Supports 12, 24, 36, 48, and 60 Vdc battery voltages
Backlit LCD display screen with 80 characters (4 lines, 20 characters per line)
Last 128 days of operational data are logged for review
Voltage step-down capability allowing a higher PV array voltage configuration
Manual and auto-equalize cycle
Firmware
This manual covers FLEXmax firmware revision 002.001.xxx.

Installation
Standards and Requirements
All installations must comply with national and local electrical codes; professional installation is
recommended.
IMPORTANT:
The charge controller is designed for indoor installation or installation inside a
weatherproof enclosure. It must not be exposed to rain and should be installed out of
direct sunlight.
Grounding
This product is intended to be installed as part of a permanently grounded electrical system as shown
in the wiring diagrams shown in Figure 6, Figure 7, and Figure 8.
The FLEXmax equipment ground is marked with this symbol:
The following important restrictions apply unless superseded by local or national codes:
The negative battery conductor should be bonded to the grounding system at only one point in the system.
If a GFDI is present, the battery negative and ground are not bonded together directly but are connected
together by the GFDI device when it is on. All negative conductor connections must be kept separate from
the grounding conductor connections.
The FLEXmax controller is not intended to be wired into a positive-ground configuration. However, certain
telecom applications may require this configuration. If it is necessary to build a positive-ground system with
OutBack products, contact OutBack Technical Support at +1.360.618.4363 before proceeding.
Additionally, consult the online forum at www.outbackpower.com/forum/, where this subject has been
discussed extensively.
If damaged or malfunctioning, the FLEXmax should only be disassembled and repaired by a qualified service
center. Please contact the local renewable energy dealer/installer for assistance. Incorrect reassembly risks
malfunction, electric shock or fire.
DC and Battery-Related Installation Requirements
Shut off all DC circuit breakers before connecting any wiring.
Torque all the FLEXmax wire lugs and ground terminals to 4 Nm (35 in-lb).
Copper wiring must be rated at 75°C or higher.
Use up to 35 mm2(2 AWG) to reduce losses and ensure highest performance of the FLEXmax (smaller cables
can reduce performance and possibly damage the unit).
Run positive and negative cables side by side.
~Keep cables together (e.g., using a tie-wrap) as much as possible to allow the inductive currents
to cancel.
~Ensure paired cables pass through the same knockout and conduit fittings.
DC battery overcurrent protection must be used as part of the installation. OutBack offers both circuit
breakers and fuses for overcurrent protection.

Mounting the Charge Controller
IMPORTANT:
Install the FLEXmax in an upright position out of direct sunlight.
Figure 4 Mounting the Charge Controller
The FLEXmax is designed to attach
directly to OutBack’s FLEXware 500 DC
and FLEXware 1000 DC enclosures
(FLEXware 500 shown) or attach to its
own charge controller brackets (FW-CCB,
FW-CCB2, and FW-CCB2T).
Mounting directly to a FLEXware DC
enclosure:
1. Remove the fan cover and bottom
cover from the FLEXmax.
2. Insert a #10 X 3/8” sheet metal screw
in the top hole on the side of the DC
enclosure. This will act as a hanging
screw for the keyhole slot at the top
center of the FLEXmax.
3. Hang the FLEXmax on the top screw
and line up its bottom two screw
holes with the holes on the enclosure.
4. Insert a #10 x 3/8” sheet metal screw
through each hole and tighten
against the enclosure (screws are
included with each DC enclosure).
5. Keep the cover off until wiring is
completed.
The conduit nipple assembly creates a
sealed connection from the FLEXmax to
the enclosure.
Mounting to Plywood
Use 1-5/8” wood screws to secure the
FLEXmax at the top slotted holes and
other interior lower holes as needed,
making sure the unit is straight and level.

times the short-circuit current.
Copper wiring must be rated at 75°C or higher.
Use up to 2 AWG (33.6 mm2) to reduce losses and ensure high performance of the
FLEXmax (smaller cables can reduce performance and possibly damage the unit).
FLEXmax 80
The output current limit of the FLEXmax 80 is 80 amps.
Install OutBack PNL-80-DC circuit breakers for disconnect and overcurrent protection
Use a minimum of #4 AWG (25 mm2) wire for the output between the FLEXmax 80 and the battery bus bar
conductors.
The largest PV array must have a rated short-circuit current of 64 amps or less under STC (Standard
Test Conditions).
Torque all the FLEXmax wire lugs and ground terminals to 4 Nm (35 in-lb).
FLEXmax 60
The output current limit of the FLEXmax 60 is 60 amps.
Install OutBack PNL-60-AC/DC or PNL-80-DC circuit breakers for disconnect and overcurrent protection.
Use a minimum of #6 AWG (16 mm2) wire for the output between the FLEXmax 60 and the battery bus bar
conductors.
The largest PV array must have a rated short-circuit current of 48 amps or less under STC (Standard
Test Conditions).
Torque all the FLEXmax wire lugs and ground terminals to 4 Nm (35 in-lb).

Wiring Compartment
WARNING: Shock Hazard
Make sure all DC circuit breakers are OFF (open) BEFORE making any wiring
connections. Use a DVM to check for voltage on all wires.
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 Figure 6, Figure 7, and Figure 8 for sample wiring diagrams.
Figure 5 Wiring Compartment
CAUTION: Equipment Damage
Each FLEXmax requires its own PV array. DO NOT PARALLEL FLEXmax PV+ and PV-
TERMINALS ON THE SAME ARRAY!
An optional battery Remote Temperature Sensor (RTS) is recommended for accurate battery charging.
Only one RTS is needed for multiple OutBack inverter/chargers and charge controller units when the system
includes an OutBack HUB and a system display.
When one RTS is used, it must be connected to the component plugged into the Port 1 of the HUB.

Operation
Operation of this unit consists of monitoring screens and programming screens. The majority of
programming screens are accessed using the main menu. See page 24.
Power Up Screens
IMPORTANT:
The default settings of the FLEXmax are for a 12 Vdc battery bank. Change the
setting after powering up if a different battery voltage is used.
Once set, the FLEXmax retains the nominal voltage setting. Following any type of
shutdown or disconnect, it will return to operation automatically.
The PV array voltage is automatically detected. The PV array voltage must never
exceed 150 Voc.
It is recommended to restore the FLEXmax to factory default settings (see page 53)
and reset the nominal voltage any time the system is substantially revised or the
controller is relocated.
The FLEXmax uses power from the battery bank to operate. The battery voltage must be at least
10.5 volts or higher to power up the FLEXmax. When battery power is detected, the FLEXmax will go
through a series of power-up screens.
