WARNING: CAREFULLY READ AND FOLLOW ALL SAFETY INSTRUCTIONS
⚫Carefully read the manual before the controller is installed and operated; retain the manual in a
safe place for future reference.
⚫The controller must not be installed or operated by any of the following persons, unless they are
under strict instruction and supervision:
a. Anyone who lacks the appropriate knowledge, experience or competence, required for safe
installation and/or usage.
b. Anyone with compromised/reduced physical, sensory or mental capabilities, which may effect
safe installation and/or usage (including children).
⚫Controller installation and operation
a. There are no serviceable parts for this controller. Do NOT disassemble or attempt to repair the
controller.
b. Install the controller in a location with good natural airflow/ventilation and sufficient unobstructed
space around it.
c. Install the controller on a non-flammable substrate and ensure there are no heat-sensitive items
in the immediate vicinity; it is normal for the controller to become hot during operation.
d. Install the controller in a location where it is protected from environmental conditions such as
direct sunlight, water, high moisture and dust, and also located well away from any flammable
liquids or gasses. Controller is for indoor use only.
e. Do not install or place/operate the controller on top of the battery, directly above the battery, or
in a sealed compartment with the battery; batteries can emit explosive gasses.
f. Do not cover or place any other items on top of the controller.
⚫Battery installation and charging
a. Install and charge the battery in a location with good natural airflow/ventilation.
b. Ensure that there are no ignition sources near the battery; batteries can emit explosive gasses.
c. Battery acid is corrosive; if battery acid comes into contact with skin immediately rinse with water.
d. Do not charge non-rechargeable batteries. And Do Not charge Li-ion batteries if the battery
temperature is below 0°C. Never charge a frozen battery.
e. Ensure that the unit is properly set up for the type of battery intended to be charged.

2
⚫Battery DC connections
a. Ensure that the DC system is fully shut down/isolated prior to disconnection of any existing
cabling and/or new connections are made to the battery/DC system.
b. Use flexible multi stranded copper cable with sufficient cross sectional area, inline with an
appropriate fuse or circuit breaker.
c. NEVER connect the solar panel array to the controller without a battery. Battery must be
connected first.
⚫Controller setup
a. Refer to the battery manufacturers instructions and specifications to ensure the battery is
suitable for use with this controller and confirm the recommended charge settings.
b. The integrated charge modes combined with adaptive charge logic are well suited for most
common battery types; such as flooded lead-acid, Gel and LiFePO4.

1 General Information
The core of the PowMr Boost-Type Solar Charge Controller lies in its adoption of cutting-edge
boost converter circuitry. This sophisticated circuit intelligently elevates the voltage output from
solar panels and matches the optimal charging voltage for batteries. By precisely adjusting the
voltage, the controller maximizes energy transfer efficiency, capturing every available watt of solar
power.
The PowMr controller incorporates advanced Maximum Power Point Tracking (MPPT) technology
to ensure that solar panels operate at their highest power output. Through continuous monitoring
and adjustment of the operating voltage point of the photovoltaic input, MPPT optimizes energy
capture under varying environmental conditions. This results in superior charging efficiency and
increased power generation, maximizing the utilization of solar energy for battery charging.
While focusing on high-efficiency operation, PowMr also prioritizes safety and protection. The
Boost-Type Solar Charge Controller integrates multiple protection mechanisms, including
overcharge, short circuit, and reverse current protection. These measures safeguard your
equipment and batteries from damage, providing reliable and secure charging performance.
The design of an LCD display allows for comprehensive monitoring of the controller's charging
status and real-time data. The display supports configuration of specific operational programs via
user-friendly operation buttons, catering to specific application requirements. Real-time data on
photovoltaic input voltage, battery charge status, charging current, voltage, and more are easily
accessible. This enables users to monitor system performance from various angles and make
informed decisions to optimize energy management.

1.1 Function
⚫Boost Voltage Charging Controller
Designed for scenarios where the photovoltaic input voltage is lower than the battery voltage, this
controller effectively boosts the voltage to match the battery's charging requirements. It overcomes
limitations caused by insufficient voltage from a single photovoltaic panel, ensuring reliable battery
charging.
⚫Integrated charge presets
Integrated charge presets combined with adaptive charge logic are well suited for most common
battery types, such as LiFePO4, Gel and flooded lead-acid.
⚫Flexible Application
Compatible with 24V/36V/48V/60V/72V system voltage.
⚫Multi-stage charge algorithm
The multi-stage charge algorithm is specifically engineered to optimize each recharge cycle and
charge maintenance over extended periods.
⚫Adaptive boost charge
Adaptive boost charge monitors the battery’s response during initial charging and intelligently
determines the appropriate boost charge duration for each individual charge cycle. This ensures
that the battery is fully recharged regardless of the discharge level or capacity and avoids excessive
time at the elevated boost charging voltage (that can accelerate battery aging).
⚫Durable and safe
i. Protection against overheating: When the equipment temperature exceeds 85℃, the control
automatically stops charging. Resume charging when the equipment temperature is 75 ℃.
ii. Protection against output short circuit.
iii. Protection against reverse polarity connection: No damage to the controller will result, when
polarity is reversed. And the controller will not work.
iv. Limit the maximum charging current. Protect battery performance and prolong battery life.
⚫Silent operation
Almost silent operation since there is no cooling fan or moving parts, cooling is via natural
convection.
⚫Lithium battery activation
Compatible with Li-ion (LiFePO₄) batteries; when the battery type parameter is set to Lithium battery
the charge cycle settings are altered to suit. Moreover, when the connected lithium battery is in a

6
protected state, the controller will activate the lithium battery using the energy from the solar panel
with a current that does not exceed the lithium battery's protection voltage and current range.
Warning: Do not charge Li-ion batteries if the battery temperature is below 0°C.

2.2 Preparing for Installation
The Controller range is designed to be wall mounted using the flanges which protrude from either
side of the heatsink backplane.
Select the Mount Location:
Before mounting, the following aspects should be considered to identify/provide a suitable and safe
location:
