INSTALLATION
Specifications subject to change without notice - please ensure you are using
the latest manual found at the manufacturer website: www.huayu-energy.com
When AC power is applied but Microinverter is not started up, about 0.1A
current and 25VA(W) power for each Microinverter may be measured by a
power meter, this power is reactive power, not from grid.
NOTE:
NOTE:
Step 5- Install an AC cable protective end cap at the end
of AC cable
7.5
NOTE:
When plugging in the DC cable, if AC is already available, the Microinverter
should immediately blink red light and will start working within the setting time
(default 60 seconds). If AC is not available, the red light will blink 3 times
quickly until AC is connected.
Step 6- Connect Microinverter to PV Modules

Installation Procedure
Step 1- Install AC branch circuit junction box
Step 2- Attach Microinverters to racking system or
the PV module frame
Prior to installing any of Microinverters, verify that the utility voltage at
the point of common connection matches the voltage rating on
Microinverter label.
Do not place the Microinverter(including DC and AC connectors)
where exposed to the sun, rain or snow, even gap between modules.
Allow a minimum of 3/4 inch(2cm). between roof and bottom of the
Microinverter to allow proper air flow.
WARNING
Wiring colour code can be different according to local regulation,check
all the wires of the installation before connecting them to the AC cable.
Wrong cabling can damage irreparably Microinverters,such an issue is
not covered by the warranty.
WARNING
Mark the location of the Microinverter on the rack, with respect
to the PV module junction box or any other obstructions.
Mount one Microinverter at each of these locations by
recommended hardware.

Step 3- Create an Installation Map
Peel the removable serial number label from each microinverter and affix
it to the respective location on the paper installation map.
Fill in the monitoring system account information to the installation map
Create a paper installation map to record microinverter serial numbers and position
in the array.
Always keep a copy of the installation map for your records.
Affix serial number labels
DO NOT exceed maximum number of Microinverters in an AC branch
circuit.

Step 4- Connect the Microinverters in parallel
2Plug the male AC connector of Microinverter into the female connector to
get it connected. AC connector interface is as follows.
1Check Microinverter technical data for the maximum allowable number of
Microinverters on each AC branch circuit.
HY-500-Pro / HY-600-Pro(-127V)
connected in parallel
Install an appropriate junction box at a suitable location on the PV racking
system(typically at the end of a branch of modules).
Connect the open wire end of the AC cable into the junction box using an
appropriate gland or strain relief fitting.
Wire the conductors of the AC(127/220/230): L - red; N - black;
PE - yellow green. Wire the conductors of the AC(208/240): L1- red;
L2 - black; PE - yellow green.
Connect the AC branch circuit junction box to the point of utility
Interconnection.
