1.1 Features
⚫Integrated Charging Presets
Integrated charging modes include adaptive charging logic, suitable for most battery types such
as flooded lead-acid batteries, gel-sealed lead-acid batteries, and lithium batteries. Specific
charging parameters for each battery type can be found in Section 3.5.
⚫Versatile Application
Compatible with 12V/24V/36V/48V system voltages.
⚫Multi-Stage Charging Algorithm
The multi-stage charging algorithm is designed to optimize each charging cycle. After the
batteries are fully charged, it maintains battery capacity by applying preset charging parameters
in specific charging stages.
⚫Maximum Power Point Tracking (MPPT) Technology
MPPT technology tracks the maximum power point voltage (Vmp) of the array as it varies with
weather conditions, ensuring the collection of maximum power from the array throughout the
day.
⚫High-Efficiency Charging
Innovative MPPT technology with a tracking efficiency of up to 99.9% and a peak conversion
efficiency of up to 97%, reducing power consumption, minimizing heat generation, and lowering
operating temperatures.
⚫Supports Up to 12 Units in Parallel
The parallel operation function allows for easy expansion of the solar panel configuration and
energy storage capacity limits, thus increasing the scale of energy storage. For detailed parallel
operation guidelines, refer to Section 7.
⚫Adaptive Boost Charging
During the initial charging phase, adaptive boost charging monitors battery response and
automatically determines the duration of the boost stage for each independent charging cycle,
ensuring that the battery is fully charged at any discharge level or capacity while avoiding
overcharging during the boost charging stage (extends battery life).
⚫Durable and Secure
a. Photovoltaic input overcurrent
b. Photovoltaic array short circuit

c. Reversed photovoltaic polarity
d. Overvoltage protection for batteries
e. Overdischarge protection for batteries
f. Over-temperature protection
⚫External Temperature Probe Configuration
Enhance precision in battery temperature monitoring by configuring an external temperature
probe. This ensures accurate temperature compensation for optimal system performance.
⚫Forced Air Cooling
Built-in cooling fan for forced heat dissipation, improving overall device operational efficiency.
⚫Lithium Battery Activation
Compatible with lithium batteries. When the battery type parameter is set to lithium batteries, the
charging cycle will be adjusted to accommodate the needs of lithium battery charging. Additionally,
when connected lithium batteries are in a protected state, the controller will activate the lithium
batteries with the energy from the solar panels, with current not exceeding the lithium battery
protection voltage and current range.
Warning: Do not charge lithium batteries when the temperature is below 0°C.

2.3 Wiring Precautions
1. Installation and wiring work should be carried out by a certified electrician.
2. Wiring should follow the sequence of Battery > PV Input.
3. To avoid short-circuits and polarity reversal, pay attention to connecting the positive (+) cable
to the device's positive (+) terminal and the negative (-) cable to the device's negative (-)
terminal.
4. Loose and/or incomplete connections can lead to cable or terminal overheating. Therefore,
tighten all cables to minimize transition resistance, using cable sizes appropriate for the specific
circuit's current rating.
2.4 Installation and Wiring Guidelines
Please refer to the following steps to complete the installation and wiring of
the controller. Alternatively, scan the QR code on the right to access the
operating guide.
Step 1. Install the controller vertically with its ports facing downward, securing it to the wall
through the four mounting holes using screws. For ease of installation, it is recommended
to use two upper screws for initial "hanging" of the device, followed by the addition of two
lower screws, and then fully tighten all four screws.
NOTE
⚫For parallel connection wiring, please refer to Chapter 7.

Step 2. Battery Wiring: Connect the battery to the controller using cables.
ATTENTION
⚫If an inverter connection is required, please refer to the diagram below.
NOTE
⚫All wiring work must be carried out by professionals.
⚫For safe operation and proper application, circuit breakers of the appropriate specifications
must be installed on the cables connected to the controller, and ensure that the
connections are tight.
⚫Ensure that all circuit breakers are in the off position before completing all wiring.
⚫Connect the positive cable terminal to the positive terminal port, and the negative cable
terminal to the negative terminal port.
⚫The above notes also apply to the PV ports and DC output ports.

Step 3. PV Wiring: Connect the photovoltaic array to the controller using cables.
Step 4. Temperature Probe Connection: Connect the temperature probe wire to the controller
and securely fix the probe end to the battery using insulation tape.
Step 5. Pre-Startup Check: Refer to the wiring diagram below. If all connections are accurate, and
all wiring is securely connected, close the circuit breakers in the order of Battery and PV
Input circuitry.
WARNING: Risk of Electric Shock!
⚫Before wiring, ensure that all power sources are turned off and follow the relevant
inspection and operation procedures.

3.4 Battery Parameter Settings
The following are configurable settings for battery-related parameters.
When there is a difference between the battery voltage monitored
by the controller and the value measured by a multimeter, the
battery voltage can be calibrated using this setting.
Long-press the BAT/▲ key to enter the setting program. Adjust
the numerical value using the BAT/▲ and BAT/▼ keys, then press the PV/SET key to save and
confirm.
In parallel operation mode, each controller must have a defined communication code. If not
operating in parallel, there is no need to configure this program.
The host is determined by the controller with the smallest communication code. During parallel
operation, if the host encounters an issue, the system will automatically designate the controller
with the next code as the new host. For instance, if the host with code 01 experiences a
malfunction, the system will redefine controller 02 as the new host.
Assuming six controllers are operating in parallel, and the communication codes for the six devices
are sequentially defined as one of the numbers from 01 to 06 (with each device having a unique
communication code, and no repetition of communication codes among the devices).

NOTE
⚫The above parameters are applicable to 12V batteries. When the connected battery voltage
is 24V/36V/48V, the range values are 2/3/4 times the specified range, respectively. The LCD
screen only displays voltage values for 12V batteries.
NOTE
⚫If the battery type is selected as "USE" (User-defined mode),
then the five charging parameters in the diagram below can
be manually set.
⚫If "USE" is not selected, there is no need to manually set
charging parameters. The controller will charge based on
preset values for the corresponding battery type. Refer to
Chapter 3.5 for charging preset values.
