45A Advanced eTracer MPPT Solar Charge Controller, 12/24/36/48V auto recognise, with RS232 CANB and Ethernet communication port

Part 1. About eTracer series MPPT Charge Solar:
eTracer is an advanced Maximum Power Point Tracking (MPPT) controller for off-grid photovortaic (PV) system up to 3KW. The controller features a smart tracking algorithm that maximizes the energy  harvest from the PV by rapidly finding  the solar array  peak power point in all the weather condition. The controller provides higher efficiency up to 98% with lower power loss. Include up to 450days logging by  connecting to internet.

The Tracer series controller is for off-grid solar system and control the charging and discharging of the battery, both suitable for the solar power system and the street light system. The controller features a smart tracking algorithm inside that maximizes the energy from the solar PV module(s) and charge the battery. At the same time, the low voltage disconnect function (LVD) will prevent the battery from over discharging.

The Tracer controller 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. In addition, the Tracer controller has a TS-R interface to allow communication with a meter for remote monitoring.
