The Enerdrive MPPT Solar Controllers adopt the advanced Maximum Power Point Tracking control
algorithm. It can minimise the maximum power point loss rate and loss time, quickly track the maximum
power point (MPP) of the PV array and obtain the maximum energy from the solar array under any
conditions; and it can increase the ratio of energy utilization in the solar system by up to 20%-30%
compared with PWM charging method. IP33 Ingress protection and isolated RS485 design further
improve the controller’s reliability and meet the dierent application requirements.
Enerdrive MPPT Solar Controllers include self-adaptive three-stage charging mode based on digital
control circuit, which can eectively prolong the lifespan of batteries and signicantly improve the system
performance. It also has comprehensive electronic protection for overcharge, over discharge and PV/
battery reverse polarity. This controller is suitable for RV, Marine, Remote O Grid monitoring and many
other applications.

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 - ensure proper ventilation is present.
• 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.
• 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.

Page 8 MPPT Solar Controller Owners Manual Rev. 1.3.
2.2 PV ARRAY REQUIREMENTS
(1) MAXIMUM PV ARRAY POWER
(1) – Enerdrive MPPT controllers include charge current limiting allowing the controller to limit the
charging current if the incoming PV array exceeds the controllers maximum charging output. This allows
the controller to protect internal charging components avoiding damage from oversized PV arrays. This
function also allows for overdriving of the solar controller increasing the amount of time the controller is
receiving its peak harvest from the PV array.
MPPT controller overdrive –
*Note: The recommended maximum solar wattage input for the EN43540 controller is 600 watts 12V.
You can however “overdrive” the MPPT controller. Please note that doing this is partially an economic
decision. You can install more power than the controller can use and this will contribute to better power
availability. Enerdrive suggest a total maximum overdrive of 20% (total 720W). On cloudy (or
intermittent sunny) days there will be little or no power shaving and the extra power will serve the
battery well with more energy harvest earlier and later in the day.*

MODEL RATED CHARGE
CURRENT
MAX. PV OPEN
CIRCUIT VOLTAGE
According to “Peak Sun Hours diagrams”, if the power of PV array exceeds the rated charging power of
the 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 1.2x the rated charging power of controller. If the maximum power of
PV array exceeds the rated charging power of the 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 correctly. Excess Solar above the 1.2x rating is best suited to a higher
rated controller, or split the array through multiple controllers.
For the recommended maximum power of PV array for this controller, please refer to the table below:
 92v at 25˚C 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.

2.4 MOUNTING
WARNING
• Risk of explosion! Never install the controller in a sealed enclosure 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 isolator or cover panels before wiring and be careful when wiring.
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 heatsync 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.
*Note: Correct ventilation is recommended.

Step 3: Grounding
Enerdrive MPPT Solar Controllers are a common-negative controller, where all negative terminals of the
PV Array, Battery and Loads can be grounded through the controller or at a common ground position
where only one negative terminal will need to be present at the unit along with the case ground being
connected. However best practice will dictate that all negative terminals should be present at the unit
both simplifying the installation and assisting with any fault nding should it be required.
Step 2: Connect the system in the order of 1 battery > 2 load>3PV array in accordance with Figure 1 -
Page 6, ”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 or main distribution point not greater than 200 mm.
• 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.
Enerdrive MPPT controllers are not suitable for positively grounded systems.
CAUTION
Page 12 MPPT Solar Controller Owners Manual Rev. 1.3.

Connect the remote temperature sensor cable to the solar controller and place the other end close to the
battery/batteries being charged.
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
Temperature Sensor
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.
NOTE
If the controller is not operating properly or the battery indicator on the controller shows an
abnormality, please refer to 5.2 “Troubleshooting” (page 24 & 25).
