and battery side, and then wait at least 5 minutes before proceeding to avoid electric shock.
4. When the inverter is running, the temperature of the casing is high. Do not touch it to avoid getting burned.
5. All electrical installations must conform to local electrical standards. The inverter should be connected to the
power grid by professionals with the permission of the local power provider.
6. During the installation process, insulated tools and personal protective equipments should be used to ensure
personal safety. To touch the electronic components of the inverter, please wear anti-static gloves, anti-static wrist
strap or anti-static clothing so as to protect the inverter against electrostatic discharge.
7. Please install the inverter at a position that is out of the reach of children.
8. Do not plug or remove the AC/DC terminal during normal operation of the inverter.
9. The actual DC input voltage should not exceed the maximum allowable DC input voltage of the inverter.
10. Select an appropriate battery that matches the system, and set the battery type correctly. If you select a
battery that does not match the hybrid inverter, the system cannot run.
11. If the battery has been completely discharged, please strictly follow the User Manual of the battery to charge
the battery.
12. For system maintenance service, please contact our local authorized service personnel or our after-sales
personnel.
13. The hybrid inverter system should be connected to the power grid after getting permission.
14. Turn off the PV switch before installing a solar PV panel during the sunny daytime, or there could be a
serious risk of electric shock.
15. Do not connect a PV string to more than one inverter, as this could cause damage to the inverters.
16. Do not connect a device that relies on continuous and stable power supply (such as a life-sustaining medical
device), to the emergency load port.

where it can be accessed easily.
(3) Do not install the inverter in an area where flammable or explosive materials are stored.
(4) Install the inverter in a well-ventilated environment, so as to facilitate heat radiation.
(5) It is recommended to choose an installation position with shade, or build a sunshade.
Fig. 4.2 Sunshade
(6) Ambient temperature: -30℃~60℃.
(7) The installation position should be far away from electronic devices generating strong
electromagnetic interference.
(8) The installation position should be on a fixed and solid object surface, such as a wall or metal
bracket.
(9) The installation position must provide reliable grounding for the inverter, and the grounding metal
conductor must be made of the same material as the reserved grounding metal conductor of the inverter.
4.3 Space Requirements

Step 3: Fix the mounting bracket. Clean the holes, drive expansion bolts into the holes using a rubber hammer.
Tighten the nut to fix the tail of the bolt using a wrench, and then remove the nut, spring washer and flat washer. Fix
the wall mount bracket to the wall with the nuts using a tightening torque of 5N•m.
4.7 Installation of Inverter
Step 1: Take the inverter out of the carton.
Step 2: If the installation position is high, you can lift up the inverter to install it to the mounting bracket. Use a
hoisting device to lift the inverter off the ground by 100mm, then pause and check the fastening of the lifting ring
and ropes. After confirming the inverter is fastened reliably, continue to lift it to its destination.
Step 3: Snap the bayonets of the inverter into the mounting bracket, and then press the inverter down to ensure
that its radiator groove fits well with the mounting bracket.

Chapter 5 Electrical Connection
5.1 Electrical Connection Overview
This product supports the following power grid systems.
Note: If the power grid system contains a N wire, the neutral to ground voltage should be lower than 10V.
NOTE
➢The connection modes between the N wire and PE wire and the GRID port and EPS port of the
inverter may be vary in different regions. Please consult your local regulatory requirements.
➢The GRID port and EPS AC port of the inverter have built-in relays. When the inverter works in off-
grid state, the built-in GRID relay will be open; when the inverter works in on-grid state, the built-in
GRID relay will be closed.
➢When the inverter is powered on, the EPS AC port will be charged; if you need to perform
maintenance of the EPS load, please power off the inverter first in order to avoid electric shock.
NOTE
The following wiring method is applicable for Australia, New Zealand and South Africa.

NOTE
➢Make sure the BACK-UP grounding wire is properly connected and secured; otherwise, the BACK-
UP function may fail in the case of power grid failure.
➢The following wiring method is applicable for regions other than Australia, New Zealand and South
Africa.
