What is the difference between MPPT function and solar inverter without MPPT function?
The I-PANDA MPPT controller uses an innovative maximum power point tracking technology that significantly increases the energy efficiency of the solar system with a conversion efficiency of up to 97%, enabling rapid scanning of the entire IV curve and tracking of the maximum power of the photovoltaic cell in seconds. Point, the maximum photocell input power can reach 3500W. In addition, the MPPT controller has over-charge, over-discharge, overload, short-circuit automatic protection and any combination of PV modules and battery reverse automatic protection, without damaging any device.
Main features of the SMART series MPPT controller:
1. The current level is divided into 20A, 25A, 30A, 40A, 50A, 60A, and the input voltage is 12V/24V/48V/96V automatic identification (the only MPPT solar controller in China that can automatically recognize 4 voltages).
2. The discharge mode has normally open mode, normally closed mode, dual time control switch mode, PV voltage control switch mode, PV control open + delay off mode, etc.; can be applied to the load for long-term power supply or load needs light control, time control Or a combination of light control and time to automatically control the switch system, such as: household power supply system, automatic detection equipment in the field, traffic lights, solar street lights, and all photovoltaic off-grid power generation systems.
3, there are dual communication protocol standard RS-232/LAN interface can be used to connect MT50 liquid crystal display unit or PC monitoring software and other communication peripherals, convenient for users to view controller operation data, modify controller control parameters, and use RS-232 based /LAN communication bus standard Internet communication protocol, communication protocol compatibility is better, and the operating state of the controller can be monitored through the network in any Internet-wide area of the world.
4. Provide professional 11-language upper computer software, which can display and set the whole working condition and working parameters of the charging and discharging system. It also has current power calculation and real-time electricity statistics recording function, which is convenient for users to check the daily, monthly, annual and total electricity and discharge power values of the equipment.
5. Forced air cooling, the fan speed is adjusted by temperature. When the internal temperature is low, the fan runs slowly or stops; when the controller stops working, the fan stops running; or the heat sink starts at 40°, and stops at 35°.
6, support PV wide voltage input, the highest PV input voltage can reach 300V, and has input overvoltage and low voltage protection.
7, customers can choose to charge 4 kinds of commonly used batteries (sealed lead-acid batteries, discharge batteries, colloidal batteries, nickel-cadmium batteries), and can be customized for other types of batteries; and there are three charging methods: constant current, Constant pressure, floating charge, and three charging methods greatly improve the service life of the battery.
