Overview; Features - Go Power MPPT-PRO User Manual

1.2 OVERVIEW

This product can keep monitoring the solar panel's generating power and tracking the highest voltage and current values
(VI) in real time, enabling the system to charge the battery in maximum power. It's designed to be used in off-grid solar
photovoltaic systems to coordinate operation of the solar panel, battery and load, functioning as the core control unit in
off-grid photovoltaic systems.
This product features an LCD screen which can dynamically display the operating status, operating parameters, controller
logs, control parameters, etc. Users can conveniently check parameters by the keys and modify control parameters to
cater to different system requirements.
The controller utilizes standard Modbus communication protocol, making it easy for users to check and modify system
parameters on their own. Besides, by providing free monitoring software, we give users the maximum convenience to
satisfy their varied needs for remote monitoring.
With comprehensive electronic fault self-detecting functions and powerful electronic protection functions built inside the
controller, component damage caused by installation errors or system failures can be avoided to the greatest extent
possible

1.3 FEATURES

Advanced dual-peak or multi-peak tracking technology, when the solar panel is shadowed or part of the panel fails
•
resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum power point.
Built-in maximum power point tracking (MPPT) algorithm can significantly increase energy utilization efficiency of the
•
photovoltaic system, which is about 15% to 20% higher than traditional PWM charging.
Provides an active charging voltage regulation feature. At battery open circuit or lithium battery BMS overcharge
•
protection, the controller battery terminal will output the rated charging voltage value.
MPPT tracking efficiency is up to 99.9%.
•
Due to an advanced digital power technology, the circuit energy conversion efficiency is as high as 98%.
•
Available in multiple battery types and support charging procedures of various types of batteries such as lithium
•
battery, colloidal battery, sealed battery, vented battery, lithium battery, etc.
A current-limited charging mode is available. When the power of solar panel is too large and the charging current
•
is higher than the rated valve, the controller automatically reduces the charging power so that the solar panel can
operate at the rated charging current.
Supports automatic identification of lead-acid battery voltage.
•
LED fault indicators and an LCD screen which can display abnormality information help users to quickly identify
•
system faults.
Historical data storage function is available, and data can be stored for up to a year
•
The controller is equipped with an LCD screen with which users can not only check device operating data and
•
statuses, but also modify controller parameters
Support standard Modbus protocol to meet communication needs in different occasions.
•
Built-in over-temperature protection mechanism ensures that when temperature exceeds the set value of the device,
•
the charging current decreases linearly with the temperature, thereby reducing the temperature rise of controller and
avoiding high temperature damage.
Temperature compensation and automatic adjustment of charge and discharge parameters help to improve battery
•
life.
Solar panel short circuit protection, battery open circuit protection and TVS lightening protection etc.
