1 General Information

1.1 Overview

Appreciate you for choosing our MPPT solar charge controller, eTracer-BND
series. Based on multiphase synchronous rectification technology (MSRT) and
common negative design, with dual-core processor architecture and advanced
MPPT control algorithm, the products in this series have the features of high
response speed, high reliability, high industrial standards, etc.
With MPPT control algorithm, in any situation, products of this series can fast
and accurately track out the best maximum power point (MPP) of PV array, in
order to obtain the maximum solar energy in time, MSRT can guarantee very
high conversion efficiency in any charge power, which sharply improves the
energy efficiency of solar system. With Modbus communication protocol
interface, it is convenient for customers to expand applications and monitor in
various fields like telecommunication base station, household 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.
Features:
 Advanced Maximum Power Point Tracking (MPPT) technology, with
efficiency no less than 99.5%.
 High quality components, perfecting system performance, with maximum
conversion efficiency of 98.7% and full load efficiency of 98%.
