1. 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.
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.

INTRODUCTION 1.5 MPPT TECHNOLOGY Maximum Power Point Tracking (MPPT) is an advanced charging technology that more efficiently 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.
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.
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.
2. TECHNICAL PARAMETERS 2.
TECHNICAL PARAMETERS STAGE 1: BULK In quick charge stage, the battery voltage has not yet reached the set value of full charge voltage (i.e. equalizing/boost charge voltage) and the controller will perform MPPT charging, which will provide maximum solar energy to charge the battery. 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.

For example, for a 24V system, if the over-discharge voltage is to be set to 22.0V, as n=24/12=2, the value needed in line with 12V system settings is 22.0V/2=11.0V, therefore the over-discharge voltage needs to be set to 11.0V.

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.
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.
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.
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 Only the battery output can be wired in parallel, the solar input of each controller must be individually wired to separate solar arrays.
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.
INSTALLATION MAIN ID 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. Note 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.

10 SYSTEM MAINTENANCE In order to maintain the best long-term performance for the controller, conduct inspections twice a year using the following points: • Make sure the airflow around the controller is unobstructed and remove any dirt or debris from the heat sink. • Check if the insulation layers of all exposed wires are damaged due to sun exposure, friction with other objects nearby, dry rot, destruction of insects or rodents. If so, it may be necessary to repair or replace the wire.
11. WARRANTY 1. 2. Go Power warrants the GP-MPPT-40 for a period of five (5) years from the date of shipment from its factory. This warranty is valid against defects in materials and workmanship for the five (5) year warranty period.
