This product is designed for solar
off-grid system (independent system), solar power plants and other systems. The
new generation of MPPT controller selection 16-bit digital signal processing
chip. It adopts advanced all-digital intelligent tracking algorithm to obtain
the maximum power point of solar modules, and real-time output current, voltage
detection, to ensure the normal battery charging and improve the utilization of
components. At the same time the system has short-circuit, overload, and a
unique battery automatic shutdown, recovery and other full-featured protection
measures.
● All-digital intelligent tracking
algorithm, the fastest access to solar modules maximum power point, the
conversion efficiency up to 95%, high utilization of PV modules.
● Increase the charging strategy
(first constant current, then constant pressure, the last float), protect the
battery and extend its service life.
● All-digital intelligent control,
with remote control.
● Standard MODBUS communication
protocol to facilitate background detection.
● With overcharge, overload, short
circuit and other sound protection, so that the machine is running more
reliable.
● Wide input voltage range, to solve
the problem of components should not be matched, selection more convenient.
● With lightning protection, solar
anti-reverse charge, battery reverse, open circuit protection.
● Small size, light weight, rack
design.
● Small power and DC power
distribution cabinet group screen, high power can be more than a parallel group
counters, easy maintenance.
● Single maximum 100A, can be
expanded according to demand.
● Touch screen display, beautiful
atmosphere.
