• With the advanced dual-peak or multi-peak tracking technology,
when the solar panel is shadowed or part of the
panel fails resulting in multiple peaks on the I-V curve, the
controller is still able to accurately track the maximum
power point.
• A built-in maximum power point tracking algorithm can
significantly improve the energy utilization efficiency of
photovoltaic systems, and raise the charging efficiency by 15% to
20% compared with the conventional PWM method.
• A combination of multiple tracking algorithms enables accurate
tracking of the optimum working point on the I-V
curve in an extremely short time.
• The product boasts an optimum MPPT tracking efficiency of up to
99.9%.
• Advanced digital power supply technologies raise the circuit's
energy conversion efficiency to as high as 98%.
• Charging program options are available for different types of
batteries including gel batteries, sealed batteries, open
batteries, lithium batteries, etc.
• The controller features a limited current charging mode. When the
solar panel power exceeds a certain level and the
charging current is larger than the rated current, the controller
will automatically lower the charging power and bring
the charging current to the rated level.
• Instantaneous large current startup of capacitive loads is
supported.
• Automatic recognition of battery voltage is supported.
• LED fault indicators and an LCD screen which can display
abnormality information help users to quickly identify
system faults.
• Historical data storage function is available, and data can be
stored for up to a year.
• The controller is equipped with an LCD screen with which users
can not only check device operating data and
statuses, but also modify controller parameters.
• The controller supports standard Modbus protocol, fulfilling the
communication needs of various occasions.
• The controller employs a built-in over-temperature protection
mechanism. When temperature surpasses the set value,
the charging current will decline in linear proportion to the
temperature so as to curb the temperature rise of the
controller, effectively keeping the controller from being damaged
by overheat.
• Featuring a temperature compensation function, the controller can
automatically adjust charging and discharging
parameters in order to extend the battery's service life.
• TVS lighting protection.
