MASTER 80A Series Self-cooling MPPT Solar Charge Controller

Introduction
This is a maximum power point intelligent tracking (MPPT) solar charge and discharge controller, and has the advantages of self-heating, automatic system identification, PV wide voltage range input, charging for multiple batteries, intelligent control discharge, RS485 communication, etc. Currently the highest-end MPPT solar charge and discharge controller.

Characteristics
1. Efficient MPPT controller algorithm, MPPT efficiency is not less than 99.5%, and the conversion efficiency of the whole machine is up to 98%.
2, charging method: third-order charging (constant current, constant voltage, floating charge), can effectively extend the life of the battery.
3, LOAD mode has normally open / normally off mode, light control mode, dual time control mode, light control - fixed time control mode.
4. Automatic identification of battery system voltage.
5, customers can choose to charge 3 kinds of commonly used batteries (sealed lead-acid batteries, colloidal lead-acid batteries, open lead-acid batteries), and can be customized to charge other types of batteries.
6, with current-limiting charging function, when the user's battery board power is too large, the controller automatically maintains the charging power, the charging current will not exceed the rated value.
7. Support multi-machine parallel connection to achieve system power upgrade.
8, with high-definition LCD display function, you can view the device operating data and working status, and can support the modification of the controller display parameters.
9, RS485 communication, can provide communication protocols, to facilitate customer unified management and secondary development.
10, support the PC software monitoring, support WIFI module to expand the implementation of app cloud monitoring.
11. The products have passed CE, ROHS and FCC certifications; they can cooperate with customers to pass various certifications.
12, the normal warranty period of three years, can provide 3 to 10 years of extended warranty service.
