2. INSTALLATION
2.1 CAUTION
• Please read the entire installation instructions to get familiar with the installation steps before
installation.
• Be very careful when installing the batteries, especially ooded lead-acid battery. Please wear
eye protection and have fresh water available to wash and clean any contact with battery acid.
• Keep the battery away from any metal objects, which may cause short circuit of the battery.
• Explosive battery gases may come out from the battery during charging, so make sure ventilation
condition is good.
• Ventilation is highly recommended if mounted in an enclosure. Never install the controller in a
sealed enclosure with ooded batteries! Battery fumes from vented batteries will corrode and
destroy the controller circuits.
• Loose power connections and corroded wires may result in high heat that can melt wire insulation,
burn surrounding materials, or even cause re. Ensure tight connections and use cable clamps to
secure cables and prevent them from swaying in mobile applications.
• The controller can work with lead-acid battery and lithium battery within its specications.
• Battery connection may be wired to one battery or a bank of batteries. The following instructions
refer to a singular battery, but it is implied that the battery connection can be made to either one
battery or a group of batteries in a battery bank.
• Multiple same models of controllers can be installed in parallel on the same battery bank to
achieve higher charging current. Each controller must have its own solar panel(s).
• Installation must be completed in accordance with applicable local standards.

2.2 PV ARRAY REQUIREMENTS
(1) MAXIMUM PV ARRAY POWER
The MPPT controller has the function of charging current/power-limiting, that is, during the charging
process, when the charging current or power exceeds the rated charging current or power, the controller
will automatically limit the charging current or power to the rated range, which can eectively protect the
charging parts of controller, and prevent damages to the controller due to the connection of some
over-specication PV modules. The actual operation of PV array is as follows:
Condition 1:
Actual charging power of PV array ≤ Rated charging power of controller
Condition 2:
Actual charging current of PV array ≤ Rated charging current of controller
When the controller operates under “Condition 1” or “Condition 2”, it will carry out the charging as per the
actual current or power; at this time, the controller can work at the maximum power point of PV array.
Condition 1:
Actual charging power of PV array＞Rated charging power of controller
Condition 4:
Actual charging current of PV array＞Rated charging current of controller
When the controller operates under “Condition 3” or “Condition 4”，it will carry out the charging as per
the rated current or power.
WARNING
When the power of PV is not greater than the rated charging power, but the maximum open-circuit
voltage of PV array is more than 100V (at the lowest environmental temperature), the controller
may be damaged.
WARNING
When the power of PV module is greater than the rated charging power, and the maximum
open-circuit voltage of PV array is more than 100V (at the lowest environmental temperature), the
controller may be damaged.

POWER
MAX. PV ARRAY
POWER
MAX. PV OPEN
CIRCUIT VOLTAGE
According to “Peak Sun Hours diagrams”, if the power of PV array exceeds the rated charging power of
controller, then the charging time as per the rated power will be prolonged, so that more energy can be
obtained for charging the battery. However, in the practical application, the maximum power of PV array
shall be not greater than 1.5 x the rated charging power of controller. If the maximum power of PV array
exceeds the rated charging power of controller too much, it will not only cause the waste of PV modules,
but also increase the open-circuit voltage of PV array due to the inuence of environmental temperature,
which may make the probability of damage to the controller rise. Therefore, it is very important to
congure the system reasonably.
For the recommended maximum power of PV array for this controller, please refer to the table below:
At 25˚C environment temperature
 At minimum operating environment temperature
CAUTION
When the PV modules connect in series, the open circuit voltage of the PV array must not exceed 92V
at 25°C environment temperature.

＊These are the maximum wire sizes that will t the controller terminals.
2.3 WIRE SIZE
MPPT Solar Controller Owners Manual Rev. 1.0.
The wiring and installation methods must conform to all national and local electrical code requirements.
Since PV array output can vary due to the PV module size, connection method or sunlight angle, the
minimum wire size can be calculated by the Isc＊of PV array. Please refer to the value of Isc in the PV
module specication. When PV modules connect in series, the Isc is equal to a PV modules Isc. When PV
modules connect in parallel, the Isc is equal to the sum of the PV modules’Isc. The Isc of the PV array must
not exceed the controller’s maximum PV input current. Please refer to the table as below:

2.4 MOUNTING
WARNING
• Risk of explosion! Never install the controller in a sealed enclose with ooded batteries! Do not install
in a conned area where battery gas can accumulate.
• Risk of electric shock! When wiring the solar modules, the PV array can produce a high open circuit
voltage, so turn o the breaker before wiring and be careful when wiring.
CAUTION
The controller requires at least 150mm of clearance above and below for proper air ow. Ventilation is
highly recommended if mounted in an enclosure.
INSTALLATION PROCEDURE
Step 1: Determination of Installation
Location and Heat-dissipation Space
Determination of installation location: The controller
shall be installed in a place with sucient air ow
through the radiators of the controller and a minimum
clearance of 150 mm from the upper and lower edges of
the controller to ensure natural thermal convection.
See Figure 2-1: Mounting
CAUTION
If the controller is to be installed in an enclosed box,
it is important to ensure reliable heat dissipation
through the box.

www.enerdrive.com.au Page 13
Step 3: Grounding
Enerdrive MPPT Solar Controllers are a common-negative controller, where all the negative terminals of
PV array, battery and load can be grounded simultaneously or any one of them will be grounded.
However, according to the practical application, all the negative terminals of PV array, battery and load
can also be ungrounded, but the grounding terminal on its shell must be grounded, which may eectively
shield the electromagnetic interference from the outside and prevent some electric shock to human body
due to the electrication of the shell.
Step 2: Connect the system in the order of 1 battery > 2 load>3PV array in accordance with Figure 2-2,
”Schematic Wiring Diagram” and disconnect the system in the reverse order 3>2>1.
CAUTION
• While wiring the controller do not close the circuit breaker or fuse and make sure that the leads of
"+" and "-" poles are connected correctly.
• A fuse which current is 1.25 to 2 times the rated current of the controller, must be installed on the
battery side with a distance from the battery not greater than 150 mm.
• If the controller is to be used in an area with frequent lightning strikes or unattended area, it must
install an external surge arrester.
• If an inverter is to be connected to the system, connect the inverter directly to the battery, not to the
load side of the controller.
For common-negative system, such as motorhome, it is recommended to use a common-negative
controller; but if in the common-negative system, some common-positive equipment are used, and
the positive electrode is grounded, the controller may be damaged.
CAUTION

Page 14
Connect the remote temperature sensor cable to the solar controller and place the other end close to the
battery.
Step 4: Connect Accessories
Step 5:Powering the controller
• If the batteries being charged are in a dierent location to the solar controller it is recommended to use
the remote temperature sensor.
Controller Mounted

Remote
Temperature Sensor
If the remote temperature sensor is not connected to the controller, the default setting for battery
charging or discharging temperature is 25 °C without temperature compensation.
Closing the battery fuse/circuit breaker will switch on the controller. Then check the status of the battery
indicator (the controller is operating normally when the indicator is lit in green). Close the fuse and circuit
breaker of the load and PV array. Then the system will be operating in the preprogrammed mode.
CAUTION
If the controller is not operating properly or the battery indicator on the controller shows an
abnormality, please refer to 5.2 “Troubleshooting”.
