INTRODUCTION 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. Warning / Caution: Result Description of condition leading to result SYMBOL 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. SYMBOL MEANING SYMBOL MEANING General Warning Hot Surface Risk of Shock Risk of Fire Risk of Electrocution Risk of Chemicals Risk of Explosion Risk of Eye Injury 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 specified, all terminal blocks should be re-tightened at least every 6 months to prevent possible fire 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 first be disconnected. • To prevent damage to the controller, ensure the solar array voltage does not exceed the maximum voltage of the solar controller. See specifications 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 fire • 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 gpelectric.com | [page 5] 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 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 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 different 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 significantly increases energy utilization efficiency 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% efficiency. • Uses advanced digital power technology to increase the circuit energy conversion efficiency to as high as 98%. • Supports multple battery chemistries, including lithium, sealed, vented, AGM, and flooded 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 identification 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 different 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.

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. FIGURE 1-2 Solar panel output characteristics curve Due to differences 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. FIGURE 1-3 Relationship between solar panel output characteristics and light [page 8] | gpelectric.com INTRODUCTION FIGURE 1-4 Relationship between solar panel output characteristics and temperature 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. (A) gpelectric.com | [page 9] INTRODUCTION (B) FIGURE 1-5 Multiple peaks resulting from partial shading 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, float and, for some types of batteries, equalization as shown in Figure 1-6. FIGURE 1-6 Battery charging stages curve graph [page 10] | gpelectric.com 2.

When the battery voltage reaches the pre-set value, Stage 2 charge will start. STAGE 2: BOOST When the battery voltage reaches the boost voltage, the controller will perform constant voltage charging. This is no longer MPPT charging, and the charging current will gradually decrease with time. STAGE 3: FLOAT Float charge is conducted following the boost charge stage. The controller will reduce the charge current to a small amount in order to prevent self-discharge of the battery and keep it fully charged. If the load exceeds this small current the battery voltage will start to decrease until it reaches the recharge voltage. When the battery voltage falls below the recharge voltage, the controller will switch back to bulk charging. STAGE 4: EQUALIZE Warning: Risk of explosion! Equalizing vented lead-acid battery may generate explosive gases. So, the battery compartment must be well ventilated. Caution: Damage of device! Equalization can increase the battery voltage to levels that may damage sensitive DC loads. It is necessary to verify that the allowable input voltage of all system loads is greater than the equalizing charge set value. Caution: Damage of device! Over charge and excessive gas evolution may damage the battery plates and cause active substances on the battery plate to come off. Equalizing charge may cause damage if voltage is too high or time is too long. Please carefully check the specific requirements of battery used in the system. Certain types of battery benefit from regular equalizing charge, which can stir electrolyte, balance battery voltage, and complete chemical reaction. The equalize charge increases the battery voltage above a standard voltage, causing vaporization of battery electrolyte. By default, this happens every 28 days. Note When the controller is not able to stabilize battery voltage due to the influence of installation environment or load, the controller will wait for 3 hours (or custom value if custom battery type used) and then automatically switch to float charge CHARGE PARAMETERS FOR VARIOUS BATTERY TYPES Set voltage Battery type GEL SEALED FLOODED LITHIUM CUSTOM High voltage disconnect 16V 16V 16V 16V 9 ~ 17V Equalize voltage —— 14.6V 14.8V —— 9 ~ 17V Boost voltage 14.2V 14.4V 14.6V 14.4V 9 ~ 17V Float voltage 13.8V 13.8V 13.8V —— 9 ~ 17V Boost return voltage 13.2V 13.2V 13.2V 13.2 9 ~ 17V Low voltage reconnect 12.6V 12.6V 12.6V 12.6V 9 ~ 17V Under voltage warning 12V 12V 12V 12V 9 ~ 17V [page 12] | gpelectric.com 3.

[page 24] | gpelectric.com 7. INSTALLATION 7.1 TOOLS AND MATERIALS NEEDED • Screwdriver. • Multimeter Note If the solar controller was purchased with a Go Power! RV Solar Power Kit the UV resistant wire is included. For instructions regarding the Go Power! RV Solar Power Kit installation, please refer to the installation guide provided with the kit 7.2 INSTALLATION AND WIRING STEP 1: CHOOSE AN INSTALLATION LOCATION The GP-MPPT-PRO controllers are designed to be mounted vertically in a battery box with sufficient ventilation and should be as close to the battery as possible. Adequate space above and below the controller is vitally important to ensure proper natural convection for heat dissipation as shown below. Avoid installing the controller in a place with direct sunlight, high temperature, and/or water. STEP 2: MARK THE MOUNTING POSITION ACCORDING TO THE MOUNTING DIMENSIONS OF THE CONTROLLER. First, place the installation guide plate at a proper position and use a marking pen to mark the mounting points. Drill 4 mounting holes of the appropriate size at the 4 marks. Fix screws into the upper two mounting holes. STEP 3: FASTEN THE CONTROLLER Align fixed holes of the controller with the two pre-fixed screws and hang the controller up. Then fix the lower two screws. gpelectric.com | [page 25] INSTALLATION STEP 4: WIRING Wiring and installation must comply with national and local electrical code requirements. The wire from the solar array most commonly enters the RV through the fridge vent on the roof or by using the Go Power! Cable Entry Plate (sold separately) that allows installers to run wires through any part of the roof. PV connections should connect directly to the controller. Positive and negative battery connections must connect directly from the controller to the batteries and positive and negative PV connections must connect directly from the solar array to the controller. Wires that are as short as possible and adequately sized (see table below) should always be used. Use of a positive and/or negative distribution bus that is properly sized is recommended between the controller and battery – do not stack wires on the battery terminals. Warning: Danger, Electric shock hazards! We strongly recommend connect a fuse or circuit breaker to the PV array and battery terminals to prevent electric shock hazards during wiring or error operation, and make sure that fuse or circuit breaker is disconnected before wiring. Model PV maximum input current Max. wire diameter at PV end (mm²/AWG) Rated charge current Battery wire diameter (mm²/AWG) GP-MPPT-PRO-60 60 11/4 60A 11/4 We recommend a wiring sequence shown below. Note 1) Note that the battery fuse shall be installed as close as possible to the battery terminal. The recommended distance is considered to be not more than 150mm. 2) The battery temperature is 25°C (fixed value) when the controller is not connected to a remote temperature sensor. [page 26] | gpelectric.com INSTALLATION BATTERY VOLTAGE SENSE The voltage measured at the battery input on the GP-MPPT-PRO-60 may differ slightly from the voltage measured directly at the battery bank terminals. This is especially true when the GP_MPPT-PRO-60 is bulk charging and is due to connection and cable resistance. The Battery Voltage Sense input enables the GP_MPPT-PRO to measure the battery terminal voltage precisely with small gauge wires that carry very little current and, as a result, have no voltage drop. A battery voltage sense connection is not required to operate your GP_MPPT-PRO-60 and it will charge your battery bank accurately without this input. However, it is recommended that these voltage sense wires are connected to ensure that the voltage and diagnostic displays are very accurate. The voltage sense wires are not included in the box with the GP-MPPTPRO-60. Wires with the following requirements can be used and should be cut to length as required to connect the battery to the voltage sense input on the GP-MPPT-PRO-60. The wires may be routed with the power conductors. • 16 to 24 AWG (1.0 to 0.25 mm2) • Twisted pair cable is recommended but not required • UL rated 300 Volt • Maximum length for each wire is 50 ft (15.24 m) gpelectric.com | [page 27] INSTALLATION 7.3 WIRING FOR PARALLEL OPERATION Multiples of the GP-MPPT-PRO-60 can be wired in parallel to charge the same battery bank for increased charging current. When wired in parallel the controllers will coordinate to ensure they work together to provide as much power to the battery bank as possible. Note Note Only the battery output can be wired in parallel, the solar input of each controller must be individually wired to separate solar arrays. While configured for parallel operation, the built-in display, remote display and Bluetooth dongle only relay information for the individual solar controller that they are connected to. This means each controller will need a separate remote display or Bluetooth dongle. To get a complete picture of the total power going to the battery bank the charge current displayed for each controller must be added together 7.3.1 WIRING DIAGRAM 1. CONTROLLER The controller can be used separately or in parallel operation and, when used in parallel, it needs to connect to the RS485 communication cable. 2. SOLAR PANEL The solar panel should be connected independently with the controller, and the power of each circuit should not exceed the rated power of the controller. 3. BATTERY BANK A battery bank consist of several batteries possessing specific voltages and capacities. 4. RS232 COMMUNICATION INTERFACE The RS232 connects to the PC or BluetoothTM and can process information from the controller offering real-time monitoring and other functionality. 5. RS485 COMMUNICATION INTERFACE The controller must be connected to the cable in order to achieve a parallel operation. MAIN [page 28] | gpelectric.com INSTALLATION 7.3.2 ORDER OF CONNECTION 1. Connect the battery first, then the solar panel and finally the load. Follow the “+” and “-” pole connection mode. 2. Connect the MAIN controller first, then connect to the next AUXILLARY controller followed by the battery, solar panel and lastly, the controller according to the ID. 7.3.3 INTERFACE DEFINITION RS485 INTERFACE NO. 1 2 3 4 DEFINITION PARALLEL OPERATION 1 12V 2 GND Black 3 D- Yellow 4 D+ Red RS485 WIRING DIAGRAM (PARALLEL OPERATION) 7.3.4 PARAMETER SETTING IN-SET MENU AU TO/SLD SET BST : 14.4V LVD : 11.0V 1. ADDRESS: the ID of the MAIN must be minimal, followed by the number from the machine to the large set. For example, the MAIN ID is set to number 1, the AUXILLARY ID of the second controller is set to number 2 and the AUXILLARY ID of a third one would be set to 3. gpelectric.com | [page 29] INSTALLATION MAIN ID Note AUXILLARY ID If the HOST fails, the minimum address ID from the controller will automatically change to the HOST and take over the rest from the controller, without causing the whole system to fail. 2. 485: parallel CHG (parallel mode) Note All controllers must be set to PARALLEL CHG mode. COMMUNICATION MODE Note PARALLEL MODE The 485 interface of ML4860 can be used to communicate with external communication, or it can be used for Parallel operation. If it is used in Parallel operation, the function of 485 must be adjusted to Parallel CHG mode. 3. The left image is the interface of the HOST controller when it is used.
