Tracer 3210A 30A MPPT LCD Solar Charge Controller 12V/24V Auto Solar Battery Charge Regulator with EBOX-BLE and  MT50 Meter             


Appreciate you for choosing MPPT solar charge controller, Tracer-A series. Based on common positive design and advanced MPPT control algorithm, with LCD displaying running status, this product is artistic, economical and practical.


With MPPT control algorithm, in any situation, products of this series can fast and accurately track out the best maximum power point (MPP) of photovoltaic array, in order to obtain the maximum solar energy in time, which remarkably improves energy efficiency. There is dual display function: local LCD panel and remote meter. With Modbus communication protocol interface, it is convenient for customers to expand applications and monitor in various fields like telecommunication base station, household system, street lighting system, wilderness monitoring system, etc.


All-round electronic fault self-test function and enhanced electronic protection function could furthest avoid damages on system components resulting from installation errors or system failures.


MT50 is an optional remote meter to monitor and program EPsolar controller, compatible with:LS-B, LS-BP,VS-BN, Tracer-BN,Tracer-A, eTracer, iTracer.


eBox-BLE-01 is a kind of serial adapter which can make our company\'s solar controller and inverter be with Bluetooth communication function, and carry out wireless monitoring, parameter settings, and etc. for the system only by cooperating with mobile phone APP
