1.1 SAFETY PRECAUTIONS
Important safety information is contained throughout this manual that should be carefully observed and followed. This
information is presented using the following format.
The information is categorized in two ways:
Warning: Bodily harm could occur if instructions are not explicitly followed. If there are any doubts about the procedure or
conditions, please call GoPower! technical support before doing anything.
Caution: Damage to property could occur if instructions are not followed properly.
The following symbols are used to indicate the type of hazard.
GENERAL SAFETY
• Read entire manual before installation
•
Any voltage above 30 VDC should be considered dangerous. Make sure power is disconnected before touching
terminals that exceed this voltage.
•
There are no parts inside the controller that need to be maintained or repaired. The controller shall never be disassembled
• Unless otherwise specied, all terminal blocks should be re-tightened at least every 6 months to prevent possible re
caused by connections that have vibrated loose.
•
Ensure all connections are tight and secure. Loose connections may generate sparks and heat. Be sure to check
connections one week after installation to ensure they are still tight.
SOLAR CONTROLLER SAFETY
• Always connect the battery BEFORE connecting the solar array to prevent damage to the controller. If the battery
wires need to be disconnected, the solar array wires should rst be disconnected.
•
To prevent damage to the controller, ensure the solar array voltage does not exceed the maximum voltage of the solar
controller. See specications table below to determine the limit for your controller.
BATTERY SAFETY
• Ensure the battery type is set correctly in the controller settings to avoid possible explosion or re
• Read manual for battery and observe safety precautions before connecting the battery to the controller
• Only use deep cycle batteries that are intended for energy storage applications

INTRODUCTION
1.2 OVERVIEW
Solar controllers, or solar charge controllers, continuously monitors the solar panel’s generating power and tracks the
highest voltage and current values (VI) in real time, enabling the system to charge the battery to maximum power. It’s
designed to be used in o󰀨-grid solar photovoltaic systems to coordinate operation of the solar panel, battery, and load,
functioning as the core control unit in o󰀨-grid photovoltaic systems.
This product features an LCD screen which displays the operating status, operating parameters, controller logs, and
control system parameters. Users can conveniently check parameters using the buttons and modify control parameters to
cater to di󰀨erent system requirements.
The controller utilizes standard Modbus communication protocol, making it easy for users to check and modify system
parameters on their own. An optional Bluetooth®adapter gives users access to 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.
1.3 FEATURES
• Advanced 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 signicantly increases energy utilization e󰀩ciency of the
photovoltaic system, (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 allows up to 99.9% e󰀩ciency.
• Uses advanced digital power technology to increase the circuit energy conversion e󰀩ciency to as high as 98%.
• Supports multple battery chemistries, including lithium, sealed, vented, AGM, and ooded Lead Acid.
• Current-limited charging mode. When the power of solar panel is too large and the charging current is higher than the
rated value, the controller automatically reduces the charging power so that the solar panel can operate at the rated
charging current.
• Supports automatic identication of lead-acid battery voltage.
• Features LED fault indicators and an LCD screen, which can display abnormal information, helps 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 allowing users to easily check device operation and statuses and
modify controller parameters
• Supports standard Modbus protocol to meet di󰀨erent options.
• Built-in over-temperature protection ensures that when temperature exceeds the set value of the device, the charging
current decreases linearly with the temperature, which reduces an increase in the controller’s temperature, avoiding
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 transient protection.

INTRODUCTION
1.5 MPPT TECHNOLOGY
Maximum Power Point Tracking (MPPT) is an advanced charging technology that more e󰀩ciently harvests power from
solar panels in all conditions. It does this by continuously tracking the I-V curve of the solar array and modifying operating
conditions to maximize output power. Figure 1-2 shows the MPPT point compared to a traditional PWM charger, which
always runs the solar array at the same operating conditions.
Due to di󰀨erences in ambient temperature and light conditions, the maximum power point often changes. The MPPT
controller can adjust parameters according to quickly changing conditions to keep the system near to its maximum
working point. The whole process is fully automatic and does not require any adjustments by users.

INTRODUCTION
In partially shaded conditions there can also be multiple peaks in the P-V curve that can confuse an MPPT algorithm.
Shown in Figure 1-5 is a series string of solar panels and a corresponding graph that shows lower maximum power points
(LMPP) and the greater maxim power point (GMPP) that will result in maximum energy transfer. The GP-MPPT-PRO
series has a smart algorithm that will always choose the right peak.

INTRODUCTION
1.6 CHARGING STAGES
Maximum power point tracking is used to charge the batteries with the highest current possible, but this is only part of the
equation. A battery cannot be charged at maximum power all the time for safety reasons, so multiple stages are used.
These stages include bulk, boost, oat and, for some types of batteries, equalization as shown in Figure 1-6.
