The Enerdrive MPPT Solar Controllers adopt the advanced MPPT control algorithm, it can minimize 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 solar array under any conditions; and it can increase the ratio
of energy utilization in the solar system by 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 has 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, PV & battery
reverse polarity. This controller can be widely used 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.
• 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.

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.

NOTE: All PV modules in a given array are assumed to be identical.
＊Isc=short circuit current(amps) Voc=open circuit voltage.
＊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:
