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

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.
