high speed and performance solar 48v 45a mppt charger controller

 

 

 

This Series MPPT solar controller is a high-end industrial class product based on multiphase synchronous rectification technology and has the features of high efficiency and reliability. The features are listed below:

 

1: 12/24/36/48VDC system voltage automatic recognition or user-defined working voltage

2: Smart tracking algorithm that finds and maintains operation at the solar array peak power point with the tracking efficiency as high as 99.7%

3: Multiphase synchronous rectification technology ensures peak conversion efficiency is up to 98.7%

4: High effective conversion efficiency at small power charging with multiphase power decentralized control and improves the generated energy

5: Double processors architecture with high speed and performance improves the response speed and optimizes the performance of the system

6: Multiphase control technology, optimizes charging current smoothness, reduces ripple and improves the system generating efficiency

7:  Excellent EMC design

8:  Excellent heat dissipation. Using the integration of cast aluminum radiator shell, the controller can be natural cooling

9: 128*64 dot-matrix LCD intuitively displays data and state, 6 buttons combinations for easy operation

10: RS232, CAN, RS485 ports via the open standard Modbus protocol are supported to meet different occasion of demand

11: Support 4 charging preprogram options: Sealed, Gel, Flooded and User-defined

12: Protection: Over temperature, over charging, PV (battery) revered, PV reverse current protect at night, over current protection

13: Actual Power Display and record function make convenience to check the datum every day, every month and every year

14:  Log function: work logs and alarm logs are all recorded

15:  Firmware update: convenience to after-service and maintenance service

The controller features a built in fuzzy control algorithm that maximizes the energy from the solar module(s) and charge the battery.

The battery charging process has been optimized for long battery life and improved system performance. The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults.

Please take the time to read this operation's manual and become familiar with the controller. This will help you make full use of all the functions and improve your PV system.
