SolarEpic Tracer 4215bn Review MPPT 40A Solar Charge Controller

Tracer BN series is EPsolar’s second generation of MPPT charge controllers. Compared with the CLASSIC Tracer series, it has extensive communication ability. And the die-cast aluminum design ensures excellent heat dispersion.

The SolarEpic MPPT 40A Solar Charge Controller 150V PV input Tracer is for off-grid solar systems and control the charging and discharging of the battery.
The controller comes with an advanced monitoring algorithm which maximizes the energy from the solar PV module(s) and charge the battery. The low voltage disconnect function (LVD) will stop the battery from over charging.
The battery charging process has been optimized for extended battery life and enhanced system performance.
The comprehensive self-diagnostics and electronic security functions can prevent damage from installing errors or system defects. Additionally, the Tracer-BN series  has a RJ45 interface to permit communication with other accessories.
