⚫To use this inverter for power generation needs the permission of the local power supply
authority.
⚫The temperature of some parts of the inverter may exceed 60°C during operation. To avoid
being burnt do not touch the inverter during operation. Let it cool before touching it.
⚫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.
⚫When wiring the lithium battery terminals, please disconnect the breaker or switch of the lithium
battery in case of a physical injury caused by the high voltage.
Inverter Storage
⚫Do not dispose of the original packing case. It is recommended to store the device in the original
packing case when the device is decommissioned.
⚫The storage temperature and humidity should be in the range of -30℃and+ 60℃, and less than
90%, respectively.
⚫If a batch of inverters needs to be stored, the height of each pile should be no more than 6
levels.

3.3 Location
The SOLXPOW X2 series and SOLXPOW X3 series inverters are designed with IP65 protection
enclosure for indoor and outdoor installations. When selecting an inverter installation location, the
following factors should be considered:
1. The wall on which the inverters mounted must be able to withstand the weight of the inverter.
2. The inverter needs to be installed in a well-ventilated environment.
3. Do not expose the inverter directly to strong sunlight to prevent excessive temperature
operation. The inverter should be installed in a place with shelter to prevent direct exposure to
sunlight and rain.
4. Install the inverter at eye level for easy inspection of screen data and further maintenance.
5. The ambient temperature of the inverter installation location should be between -30℃and 60℃.
6. The surface temperature of the inverter may reach up to 75℃. To avoid risk of burns, do not
touch the inverter while it's operating and inverter must be installed out of reaching of children.
3.3.1 Installation location
Select an optimal mounting location for safe operation, long service life and expected performance.
1. The inverter with protection rating IP65 can be installed both indoors and outdoors.
2. Install the inverter at a place convenient for electrical connection, operation, and maintenance.
Figure 3-2 Recommended installation location
WARNING
⚫Do not put flammable and explosive articles around the inverter.

1. Use the wall bracket as the template to mark the position of 5 holes on the wall.
Figure 3-6 Marking hole position using installation bracket
2. Use an electrical driller with 10mm diameter bit to drill 5 holes in the wall with 80mm depth.
3. Insert the expansion tubes into the holes and tighten them, then fix the bracket onto the wall with
expansion screws by using a cross screwdriver.
WARNING
⚫Before drilling, make sure to avoid any buried water tube and electric wires in the wall.

3.4.3 External Ground Connection
Connect the inverter and ground bar through PE wire to achieve the purpose of grounding
protection. Please always remember wiring the PE wire before wiring other wires.
DANGER
⚫Do not connect the N-wire as a protective ground wire to the inverter casing. Otherwise, it
may cause electric shock.

User Manual
SOLXPOW X2 Series & SOLXPOW X3 Series

Ground terminal connection steps:
1. The external grounding terminal is located in on the lower right side of the inverter.
2. Fix the grounding terminal to the PE wire with a proper tool and lock the grounding terminal to
the grounding hole in the lower right side of the inverter.
Figure 3-9 Grounding terminal connection
NOTICE
⚫Reliable grounding is good for resisting surge voltage shock and improving EMI performance.
⚫Inverters must be well-grounded.
⚫For a system with only one inverter, just ground the PE cable.
⚫For a multi-inverter system, all inverters PE wire need to be connected to the same
grounding copper bar to ensure equipotential bonding.

4 Electrical Connection
DANGER
⚫A high voltage in the conductive part of the inverter may cause an electric shock. When
installing the inverter, make sure that the AC and DC sides of the inverter are completely de-
energized.
⚫Do not connect the N-wire as a protective ground wire to the inverter casing. Otherwise, it
may cause electric shock.
WARNING
⚫Do not ground the positive or negative pole of the PV string, otherwise it will cause serious
damage to the inverter.
⚫Static may cause damage to the electronic components of the inverter. Antistatic measures
should be taken during installation and maintenance.
NOTICE
⚫Do not use other brands or other types of terminals other than the terminals in the accessory
package. PowMr has the right to refuse all damages caused by the mixed-use of terminals.
⚫Moisture and dust can damage the inverter, ensure the cable gland is securely tightened
during installation. The warranty claim will be invalidated if the inverter is damaged as a
result of a poorly connected cable connector.
