2. Safety & Warning 2. Safety & Warning
2.2 General Safety Instructions
WARNING:
Electrical installations must be done in accordance with the local and national
electrical safety standards.
WARNING:
Please don’t connect PV array positive (+) or negative (-) to ground, it could
cause serious damage to the inverter.
WARNING:
Only devices in compliance with SELV (EN 69050) may be connected to the
RS485 and USB interfaces.
WARNING:
Do not touch any inner live parts until 5 minutes after disconnection
from the utility grid and the PV input.
CAUTION:
The PV array supplies a DC voltage when they are exposed to sunlight.
CAUTION:
Risk of electric shock from energy stored in capacitors of the Inverter, do not
remove cover for 5 minutes after disconnecting all power sources (service technician
only). Warranty may be voided if the cover is removed without authorization .
CAUTION:
The surface temperature of the inverter can reach up to .60℃ (140 ℉)
To avoid risk of burns, do not touch the surface of the inverter while it’s operating.
Inverter must be installed out of the reach of children.
WARNING:
To reduce the risk of fire, over-current protective devices (OCPD) are
required for circuits connected to the inverter.
The DC OCPD shall be installed per local requirements. All photovoltaic source
and output circuit conductors shall have that comply with the NECisolators
Article 690, Part II.
CAUTION:
Risk of electric shock, do not remove the upper cover ( lower cover can be
removed for connection). There is no user serviceable parts inside, refer
servicing to qualified and accredited service technicians.
NOTE:
PV module used with inverter must have an IEC 61730 Class A rating.
WARNING:
Operations below must be accomplished by licensed technician or Solis
authorized person.
WARNING:
Operator must put on the technicians’ gloves during the whole process in case
of any electrical hazards.
WARNING:
For PV system, between the PV string and PV input of the inverter, it is
required to install a DC isolator to meet local installation regulations.

2. Safety & Warning

.6. .7.
2.4 Notice for Disposal
This product shall not be disposed of with household waste. They should
be segregated and brought to an appropriate collection point to enable
recycling and avoid potential impacts on the environment and human health.
Local rules in waste management shall be respected .
3. Installation
3.1 Select a Location for the Inverter
To select a location for the inverter, the following criteria should be considered:
Exposure to direct sunlight may cause the output power to decrease. It must install
the inverter indoors and avoid direct sunlight and rain.
This inverter is IP21 rated and it can be used indoors with environmental pollution
level II. Please install it indoors to avoid rain, spraying water or splashing water.
To avoid overheating, always make sure the flow of air around the inverter is not
blocked. A minimum clearance of 200mm should be kept between inverters or
objects and 500mm clearance between the bottom of the machine and the ground.
Install vertically with a maximum incline of +/- 5 degrees, exceeding this may cause
output power derating.
Install on a wall or strong structure capable of bearing the weight of the machine (14kg).
WARNING: Risk of fire
Despite careful construction, electrical devices can cause fires.
Do not install the inverter in areas containing highly flammable materials
or gases.
Do not install the inverter in potentially explosive atmospheres.
WARNING:
Solis requires using two magneto-thermic automatic switchs with an RCD
module (with adequate voltage and current rating basing on the grid
characteristics and on the output current of the inverter) with a sensitivity of
30mA, B-type. One switch with the RCD module needs to be installed on the
AC input side, one RCD needs to be installed on the AC backup output side. It is recommended that the inverter is installed in a cooler ambient which doesn't
exceed 131℉/55℃.

Fix the two holes on the top of the machine and one hole in the box with screws.

3.4 PV Input Terminal Assembly
Please ensure the following before connecting the inverter:
Make sure the voltage of the PV string will not exceed the max DC input voltage
(550Vdc). Violating this condition will void the warranty.
Make sure the polarity of the PV connectors are correct.
Make sure the battery, AC Input, and AC Output are all in their off-states.
Make sure the PV resistance to ground is higher than 20K ohms.
PV wire diameter requirements: .12AWG(3.3mm²）

1. Remove insulation sleeve 10mm for positive and negative conductors.
3. Please ensure the secure and correct polarity connection between PV modules and PV
input connectors or the system will be damaged. Connect the positive pole (+) of the
connection cable to the positive pole (+) of the PV input connector. Connect the negative
pole (-) of the connection cable to the negative pole (-) of the PV input connector.
