4. Product Features
Dear users, thank you for choosing this product. This product is a negative grounded buck
MPPT charging controller. The PV input adopts MPPT digital charging method, and the
running status and related parameters can be displayed on the on-board screen or an
external screen (optional accessory). It also supports Bluetooth app for online modification
and viewing of controller parameters, as well as viewing the current status or history. It is
widely used in small-scale power generation and energy storage systems, and has the
following remarkable features:
Buck MPPT charging method,negative grounded design, App operation.
· The combination of multiple MPPT algorithms ensures maximum power charging
under complex weather conditions.
· Multi-peak detection, to avoid running at low-power peaks when there are multiple
peaks.
· When the PV input exceeds the rated power (and less than 1.25 times), the controller
maintains the rated power operation (limit operation).
· Three-stage Charging: according to the characteristics of the battery, it has the modes of
equalized charging, boost charging, and float charging (lithium batteries only have boost
charging).
· It supports Sealed (SEL), GEL, Flooded (FLD), Lithium battery (LI) and User-defined (USE)
types of batteries, and it can also be conveniently selected through pressing keys, external
screen (optional) and APP.
· Liquid crystal display: through an LCD screen, users can check the system's operating
status and set some parameters.
· In the case of non-charging, the controller works in low power consumption mode and
consumes less power.
· In non-lithium battery mode, it supports 12V/24V/36V/48V automatic identification, and
the lithium battery requires the user to set the system voltage.
· Reverse connection protection: battery polarity reverse protection and PV polarity
reverse protection.
· Support RS485 communication mode, adopt Modbus communication protocol
(support customer customized protocol and communication media).
· Supports up to 9 machines in parallel, users can expand product capacity by
connecting data lines in parallel use.
· Historical data: the system retains 300 days of historical data (charging capacity,
maximum charging power, maximum battery voltage, and minimum battery voltage
number of days ago).
· Accumulated data: accumulative charging capacity, number of running days.
