HES7120-PV HYBRID ENERGY CONTROLLER USER MANUAL
— The busbar has the functions of over and under voltage, over and under frequency, loss of phase,
reverse phase sequence, over power, reverse power and voltage imbalance. PV has the functions of
over and under voltage, over and under frequency, loss of phase, reverse phase sequence and
voltage imbalance.
— Voltage, current and power display of up to 4 solar panel channels can be set.
— Sampling up to 3 solar panel temperatures and 3 solar irradiance to calculate the maximum
capacity of PV.
— A variety of temperature, pressure, liquid level, power transmitter, light radiation sensor curves can
be used directly, and sensor curves can be customized, among which programmable 2 and
programmable 4 can be connected to resistance, voltage or current type sensors.
— Busbar power can be achieved by current transformer, power transmitter and communication.
— With variety of protocols RS485 interface and can communicate with various inverters with RS485
interface.
— With automatic closing and start function, automatic soft loading and soft unloading function.
— With minimum load power setting of the busbar to prevent reverse power transmission to the
busbar.
— With up to 6-way busbar power, and calculates the total load power of busbar in real time
according to the state of input port.
— Control and protection functions: realize automatic start/stop of PV power generation inverter,
closing and opening of breaker switch, perfect fault display protection and other functions.
— Three active power control modes (fixed power, busbar control power, inverter control).
— Four reactive power control modes (fixed power, busbar control power, power factor, inverter
control).
— Parameter setting function: allows the user to change and set its parameters, which will not be lost
when the system is powered off. Most parameters can be adjusted from the front panel of the
controller, and all parameters can be adjusted by PC through USB or network interface.
— The power supply has a wide range of DC (8-35) V, which can adapt to different power supply
voltage environments.
— With event log and real-time clock.
— Data recording function of busbar voltage, busbar frequency, busbar current, busbar power, PV
generation voltage, PV generation frequency, PV current, PV power, sensor, etc. one minute before
stop fault (can be set), with a maximum of 5 records; maximum records are 5.
— With accumulation, user A, user B accumulation (running time, start times, power).
— A rubber sealing ring is designed between the shell and the control panel, and the waterproof
performance can reach IP65.
— The controller is fixed with metal clips.
— Modular structure design, pluggable terminal block, embedded installation mode, compact
structure, convenient installation.
