1.1 Overview
Appreciate you for choosing MPPT solar charge controller, Tracer-BN series.
Based on common negative design and advanced MPPT control algorithm, with
die-cast aluminum design for heat dissipation, products in this series are 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. With Modbus communication protocol interface, it is convenient
for customers to expand applications and monitor in various fields like
telecommunication base station, household system, caravan 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.
