Installing the Inverter
2.2
When drilling holes, avoid the water pipes and power cables buried in the wall.
1. Install the mounting bracket.
•M6x60 expansion bolts are delivered with the inverter. If the length and number of the bolts do
not meet installation requirements, prepare M6 stainless steel expansion bolts by yourself.
•The expansion bolts delivered with the inverter are used for solid concrete walls. For other types
of walls, prepare bolts by yourself and ensure that the wall meets the load bearing requirements
of the inverter.
•Loosen the nuts, flat washers, and spring washers of the two expansion bolts.
Prepare an anti-theft lock suitable for the lock hole diameter (Ф8 mm) and ensure that the lock can
be installed successfully. An outdoor waterproof lock is recommended.
2. Install the inverter on the mounting bracket. 3. (Optional) Install an anti-
theft lock.

Installing the PE Cable
3.2
•Connect cables in accordance with the local installation laws and regulations.
•Before connecting cables, ensure that the DC switch on the inverter and all the switches
connecting to the inverter are set to OFF. Otherwise, the high voltage of the inverter may result
in electric shocks.
Do not connect the neutral wire to the enclosure as a PE cable. Otherwise, electric shocks may occur.
•The PE point at the AC output port
is used only as a PE equipotential
point, and cannot substitute for
the PE point on the enclosure.
•It is recommended that silica gel
or paint be used around the
ground terminal after the PE cable
is connected.

Installing the AC Output Power Cable
3.3
•Ensure that the protection layer of the AC output power cable is inside the connector, the core
wires are totally inserted into the cable hole, and the cable is connected securely. Failing to do
so may cause device malfunction or damage.
•The hex key is delivered with the inverter and bound to the hanging kit at the bottom of the
inverter.
1. Connect the AC output power cable to the AC connector.

3. Check the route of the AC output power cable.
1. Use the Amphenol Helios H4 PV connectors supplied with the inverter. If the PV connectors are
lost or damaged, purchase the connectors of the same model. The device damage caused by
incompatible PV connectors is not covered under any warranty.
2. Crimp the metal stamping forming contacts using crimping tool H4TC0003 (Amphenol,
recommended) or H4TC0002 (Amphenol).
3. Ensure that the PV module output is well insulated to ground.
4. The DC input voltage of the inverter shall not exceed 1080 V DC under any circumstance.
5. Before installing the DC input power cable, label the cable polarities to ensure correct cable
connections.
6. If the DC input power cable is reversely connected, do not operate the DC switch as well as
positive and negative connectors immediately. Failing to do so may cause device damage, which
is not covered under any warranty. Wait until the night when solar irradiance declines and the PV
string current drops to below 0.5 A. Then set the DC switch to the OFF position, remove the
positive and negative connectors, and correct the polarities of the DC input power cable.

•If you prepared a Smart Dongle without a SIM card, you need to prepare a standard SIM card (size:
25 mm x 15 mm) with the capacity greater than or equal to 64 KB.
•When installing the SIM card, determine its installation direction based on the silk screen and arrow
on the card slot.
•Press the SIM card in place to lock it, indicating that the SIM card is correctly installed.
•When removing the SIM card, push it inwards to eject it.

Ensure that the cable
cannot be pulled out
after being crimped.
Ensure that the locking nut
is secured.
Ensure that the cables are
correctly connected. (The DC
voltage of a multimeter should
not be less than 1100 V).
