POW-Keeper1220 - Powmr MPPT 20A Solar Charger Controller

Powmr MPPT 20A Solar Charger Controller Overview

Thank you for selecting MPPT series solar charge controller with the most advanced MPPT control algorithm and the maximum power point of the pv array can be quickly tracked in any environment so that it can get the maximum energy from the solar panel and significantly improve the utilization of energy in solar system. The machine has the dual display function of LCD and Remote header (optional) and standard communication interface, convenient for user extension application and satisfy different monitoring needs to the maximum extent. It can be used in communication base station, home power supply system, traffic light, solar street lamp, courtyard lamp system, etc.

It comes with a number of outstanding features, such as:

• Advanced MPPT maximum power point tracking technology, the tracking efficiency is no less than 99.5%. 
• High quality components are used to improve the system performance, and the maximum conversion efficiency can reach97%. Super fast maximum power tracking speed while ensuring tracking efficiency. 
• Accurate identification and tracking of the maximum power point of multi-wave peak. 
• Reliable maximum input power of pv array to ensure the safety of equipment. 
• Wide pv array maximum power point operating voltage range. 12/24v automatic voltage identification
• The LCD is designed to dynamically display the operation data and working status of the equipment. 
• Various load control modes: general mode, light control mode, dual time mode, pure charger mode and timing mode. 
• Seal, GEL, Flooded, LifePO4 and Li (NiCoMn) O2 charging process can be selected. 
• The function of battery temperature compensation. 
• Power statistics recording function. 
• Use the RS485methods to maximize the communication needs of different occasions. 
• Support PC monitor, external display unit and other peripherals, realize real-time data view and parameter setting function.

Order of connection:

① Connect batteryNotice: The battery terminal shall be installed with insurance, and the installation distance shall not exceed 50mm. ② Connected Load
③ Connect pv array
④ Controller is powered on Connect the battery, identify the voltage of the control system and observe whether the display screen is lighted. If it doesn't work or the display is abnormal, refer to section 6 for troubleshooting.

NOTICE: This series of MPPT is a common positive: controller, pv array, battery and load of the positive pole can be grounded at the same time. NOTICE: If the inverter or other starting current is loaded. Sin the system, please connect the inverter directly to the battery. Do not connect with the controller's load terminal.

INSTALLATION IMPORTANT NOTE: 

• (1) The controller should be installed well-ventilated place, avoid direct sunlight, high temperature and do not install in location where water can enter the controller.
• (2) Please select correct screw to fix the controller on the wall or other platform. Screw M4 or M5, screw cap diameter less than 10mm 
• (3) Please reserve enough space between the wall and controller, to allow for cooling and cable connection.
• (4) The mounting holes distance is 155.8mm*63mm, diameter of the hole is 5mm.
• (5) Connect components to the charge controller in the sequence, please pay much attention to the positive" and "negative", don't insert the fuse or turn on the breaker during the installation. When disconnecting the system, the order will be reserved.
• (6) Always connect the battery first, in order to allow the controller recognize the system voltage.
• (7) The battery fuse should be installed as close to battery as possible.
• (8) The distance between the battery fuse to battery group is within 150mm (9) Positive grounding controller, any positive connection of solar load or battery can be earth grounded as required.
• (10) All terminals are in tight status after leaving factory, in order to well connected, please loose all terminals at first.
• (11)The sequence of connection please do not free change, otherwise cause system voltage recognition fault.
• (12) The length of cable between battery and controller as shorter as possible. Suggest 30cm to 100cm.
• (13) lf short circuit happened on the terminals of controller, it will be result in fire or explode. Please be careful. (We strongly suggest to connecting a fuse at the battery side 1.5 time of rated current of
• controller)
• (14) lf the battery reverse connection, the output of controller also same with battery polarity, please do not connect any load with controller at that time, or the load and controller will be destroyed.
• (15) The voltage of solar panel is very high under sunshine, high voltage can cause injury or destroy controller, make sure PV max under required safety MPP range.
• (16) Avoiding injury from load voltage, please close to the output of controller with button at first, then connected the load on the controller. The controller do not offer reverse connection protection for load, so please take care, reverse connection for load will be destroy bulb.
