1.4 Additional Information

1.5.2 Safety Warning
Any installation and operation of inverter must be performed by qualified electricians. The appliance is not to
be used by children or persons with reduced physical sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction.
Before any wiring connection or electrical operation on inverter, all battery and AC power must be disconnected
from inverter for at least 5 minutes to make sure inverter is totally isolated to avoid electric shock.
During operation, the upper lid of the enclosure and the enclosure body may become hot. Only touch the lower
enclosure lid during operation, and make sure the inverter is untouchable for children
Usage and operation of the inverter must follow instructions in this user manual, otherwise any injury or damage
and warranty is not warranted by Huayu New Energy.
Do not open inverter's cover or change any components, otherwise the warranty commitment for the inverter will
be invalid.
DC differential currents from battery are created , thus an external RCD (type A) can be used(30mA) in the AC
output of the HYH-3.6K-AC. As the HYH-3.6K-AC used with PV inverters in the system, so the PV inverters are
creating residual current too, in order to prevent unwanted triggering during operation, we recommend that the
rated residual current of the RCD has to be min 50mA.
In Australia, the inverter internal switching does not maintain neutral integrity, which must be addressed by
external connection arrangements like in the system connection diagram for Australia on page 8
2. Working Modes Introduction
MODE 1:
It is applied in the micro-grid system. During the day, the energy generated by the diesel generator is stored
in the battery, and the power is supplied to the load from the network at night. It is suitable for the micro-grid
environment that needs quiet electricity at night. In this mode, 10 units can be connected in parallel with a
power of 36kW.
HYH-3.6K-AC MICRO-GRID MODE:
0403
This mode needs special hardware
versionfirmwa and re version, please
contact to Huayu(Ning Bo)New Erengy
Technologies Co.,Ltd.
AC-Coupled energy storage inverter is designed for indoor and outdoor usage with existed
grid-connected solar power systems want to retrofit with batteries to store energy. It has five modes to
satisfy the PV+ Storage system
When PV power is sufficient enough with excess power
rested after supplying the loads, the excess power will
be firstly used to charge the battery by HYH-3.6K-AC,
if there is still power rested after that then it will be feed
-in to the grid.
When the PV power is not sufficient enough,
HYH-3.6K-AC discharges the battery power to
the household load, so that the power which is
taken from the grid as little as possible.
When grid power fails, immediately, the HYH-3.6K-AC
discharges the battery power to the important household
load using uninterrupted power supply technology which
will guarantee the power supply stability and continuously
of important loads. (Notice that it's required to enable the
UPS function to activate this working mode)
Battery can be charged by grid power (AC charge mode)
by enable relevant functions and make right settings
according to the real demands on the AC charge function
via LCD operation, monitoring website or the APP.
MODE 3: MODE 4:
HYH-3.6K-AC can be set to “Force Discharge” mode,
no matter PV inverter output energy is sufficient or not,
the HYH-3.6K-AC discharges the power to the grid and
Time &power &SOC limit can be set flexibly via LCD
operation, monitoring website or APP.

Connecting the AC output of HYH-3.6K-AC
to the grid, and connecting the EPS output of
HYH-3.6K-AC to the important load as the
above wiring diagram.
1.An external RCD breaker can be used(I≥40A,In≥30mA) in the EPS output of the
HYH-3.6K-AC and the input of household Load.
2.As the HYH-3.6K-AC used with PV inverters in the system, so the PV inverters are
creating residual current too, in order to prevent unwanted triggering during operation,
we recommend that the rated residual current of the Main RCD Breaker has to be ≥50mA.
3.The AC breaker in the Grid output of the HYH-3.6K-AC is suggested to be ≥40A.And
the DC breaker of the battery is suggested to be ≥100A.For batteries with attached switch,
the external DC switch is not necessary.
CAUTION!
NOTE: For Australian and New Zealand safety country, the neutral cable of On-Grid side and Back-Up side must
be connected together, please refer to page 8: the wiring diagram for Australian and New Zealand grid system.

Users can start-up HYH3.6K-AC through following steps
Step1:Turn on the grid side AC circuit breaker to connect to Grid
Step2:Turn on the battery side DC circuit breaker to connect to Battery
Step3:When the working information is displayed on LCD screen and the icon of the battery is flashing,
then set the type of the battery and finish, the inverter will restart after the setting.
Step4:When the working information is displayed on LCD again and the battery is not flashing, it means that the
HYH-3.6K-AC system is starting up successfully.
5.2 Shut-down the HYH-3.6K-AC System
Step1:Turn off all the circuit breakers and switches, make sure that the grid connection, battery connection,
PV connection and UPS connection are all disconnected by turning off the relevant breakers and switches.
Step2:Wait for 5mins and the HYH-3.6K-AC is shut down completely
