PWM charge controller VS-BN Series

batterysolarCE

The controller could charge battery and discharge automatically for off-gridphotovoltaic (PV) systems. The charging process has been optimized forlong battery life and improved system performance. The comprehensiveself-diagnostics and extensive electronic protection can prevent damageagainst incorrect wiring or system faults. • 32 bit MCU with high speed and high performance • 12 bit A/D high-precision sampling to ensure accuracy • Excellent EMC design • Nominal system voltage automatic recognition or user-defined working voltage • High efficient Series mode PWM charging, increase the battery lifetime and improve the solar system performance • Use MOSFET as electronic switch, without any mechanical switch • Wide feasibility and, recognize day or night automatically • Graphical dot-matrix LCD and 4 buttons combinations as HMI (human-machine interface) for full menu and easy operation • Humanized design of browser interface to facilitate the operations • All of control parameters could be set and modified • Several load control methods are supported to convenient for different demand • Support 4 charging preprogram options: Sealed, Gel, Flooded and User-defined • Adopt temperature compensation and update charging and discharging parameters automatically to improve the battery lifetime • With the feature of input filter, the voltage spike could be restrained effectively • Actual Power Display and record function make convenience to check the datum every day, every month and every year • RS-485 ports via the open standard Modbus protocol are supported for long-distance communication and communication
