Safety
1. Safety
Before using the inverter, please read all instructions and cautionary markings on the unit and in this
manual. Put this manual to a place where you can take it easily.
Our Power2SA inverter strictly conforms to related safety rules in design and test. Please follow the
local laws and regulations during installation, operation and maintenance. Incorrect operation may cause
injury or death to the operator or a third party, and damage to the inverter and other properties belonging
to the operator or a third party.

1.2 Safety Precaution
Installation, maintenance and connection of inverters must be performed by qualified personnel, in
compliance with local electrical standards, wiring rules and requirements of local power authorities and/
or companies.
The temperature of some parts of the inverter may exceed 60℃ during operation. Do not touch the
inverter during operation to avoid being burnt.
Ensure children are kept away from inverters.
Don’t open the front cover of the inverter. Apart from performing work at the wiring terminal (as
instructed in this manual), touching or changing components without authorization may cause injury
to people, damage to inverters and annulment of the warranty.
Static electricity may damage electronic components.Appropriate methods must be adopted to prevent
such damage to the inverter; otherwise the inverter may be damaged and the warranty annulled.
Ensure the output voltage of the proposed PV array is lower than the maximum rated input voltage of
the inverter; otherwise the inverter may be damaged and the warranty annulled.
When exposed to sunlight, the PV array generates dangerous high DC voltage. Please operate according
to our instructions, or it will result in danger to life.
PV modules should have an IEC61730 classArating.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
Completely isolate the inverter before maintaining. Completely isolate the inverter should: switch off
the PV switch, disconnect the PV terminal, disconnect the battery terminal, and disconnect the AC
terminal.
Prohibit inserting or pulling the AC and DC terminals when the inverter is running.
In Australia, the inverter internal switching does not maintain the neutral neutral continuity. And neutral
integrity must be addressed by external connection arrangements.
Don’t connect Three phase hybrid inverter in the following ways:
BACKUP Port should not be connected to grid;
The single PV panel string should not be connected to two or more inverters.
After the inverter is powered off, the remaining electricity and heat may still cause electric shock and body
burns. Do not touch parts of inverter for 10 minutes after disconnection from the power sources.

Product Introduction
2. Product Introduction
2.1 Overview
Power2SA Inverter
The Power2SA inverter is a high-quality inverter which can convert solar energy to AC energy and store
energy into battery. Typically, a Power2SA inverter system consists of PV array, ESS inverter, battery,
loads and electricity sensor.
The energy generated by inverter can be preferentially supplied to its self-consumption, stored in the battery
for future use or fed into public grid.

3.2 Selecting the Mounting Location
3.2.1 Installation Environment Requirements
Installation
12 Power2SA Inverter User Manual
a. With an IP65 protection rating, the inverter can be mounted indoors or outdoors.
b. The
mounting location must be inaccessible to unrelated personnel since the enclosure and heat sinks
are extremely hot during operation.
c. Do not install the inverter in areas containing highly flammable materials or gases.
d. To ensure optimum operation and long service life, the ambient temperature must be below 50℃.
e. The inverter must be mounted in a well-ventilated environment to ensure good heat dissipation.
f. To ensure long service life, the inverter must not be exposed to direct solar irradiation, rain,
or snow. It is recommended that the inverter be mounted in a sheltered place.
g. The carrier where the inverter is mounted must be fire-proof. Do not mount the inverter on flammable
building materials.
h. Do not install the inverter in a rest area since it will cause noise during operation.
i. The installation height should be reasonable, and please make sure it is easy to operate and view the display.
j. Product label and warning symbols shall be clear to read after installation.
k. Please avoid direct sunlight, rain exposure, snow cover.
No direct sunlight No rain exposure No snow cover

3.2.2 Mounting Requirements
Mount the inverter vertically or tilted backward by max 15°. The device can not be installed
with a wrong mode and the connection area must point downward.
3.2.3 Installation Space Requirements
To ensure the inverter is normal and easy to operate, there are requirements on available spaces of the
inverter, e.g. to keep enough clearance. Refer to the following figures.

Before mounting the inverter, you have to prepare
expansion screws and a security screw.
Step 1. Install the mounting bracket
Step 2. Install the inverter on the mounting bracket. Then lock the inverter using the security
screw. Refer to Figure e, Figure f.
Before drilling the hole on the wall, ensure no damage on the electric wire
and/or water pipe inside the wall.
DANGER
To prevent potential damages and injuries from inverter falling down,
please hang the inverter on the bracket, do not loosen grip unless confirm
that the inverter is well-mounted.
CAUTION
3.3 Mounting
1. Use a level ruler to mark the position of the 3 holes on
the wall. Refer to Figure a. And drill 3 holes, 16mm in
diameter and 55mm in deep. Refer to Figure b.
2.
Knock the expansion screw kit into the hole together
with a hammer. Refer to Figure c.
Note: Do not remove the nut unit in this step.
3. After tightening 2-3 buckles, the expansion bolts are
tight and not loose, and then unscrew the bolts, spring
washer, gasket. Refer to Figure c.
4. Install and fix the mounting bracket on the wall.
Refer to Figure d.

A protective earth (PE) terminal is equipped at the side of the inverter. Please be sure to connect this
PE terminal to the PE bar for reliable grounding. AWG 2 or 4 yellow green lines are recommended.
CAUTION If the positive pole or negative pole of the PV array is required to
be grounded, then the inverter output (to AC grid) must be isolated
by transformers in accordance with IEC62109-1, -2 standards.
The inverter must be grounded; otherwise, there may be electric shock
risk.
