3. Installation
3.1 Select a Location to Install the Inverter
When selecting a location for the inverter, the following criteria should be considered:
Exposure to direct sunlight may cause output power derating due to overheating
It is recommended to avoid installing the inverter in direct sunlight. The ideal location is
one where the ambient temperature does not exceed 40°C.
It is also recommended to install the inverter somewhere the rain and snow will not land
directly on it. The ideal installation location is on a north-facing wall under an eave.

User Manual
3. Installation
When selecting a location for the inverter, consider the following:
The temperature of the inverter heat-sink can reach 75℃.
The ambient temperature and relative humidity of the installation environment should
meet the following requirements:
If multiple inverters are installed on site, a minimum clearance of 150mm should be kept
between each inverter and all other mounted equipment. The bottom of the inverter should be
at least 800mm above of the ground or floor.
The LED status indicator lights located on the inverter's front panel should not be blocked
Adequate ventilation must be present if the inverter is to be installed in a confined space.
CAUTION: Hot Surface
Made of non-inflammable materials
Max. load bearing capacity ≥ 4 times of inverter weight
3.1.2 Consult technical data
Consult the technical specifications sections at the end of this manual for additional environmental
condition requirements (temperature range, altitude, etc.)
This model of Solis inverter must be mounted vertically (90 degrees or backwards less than or
equal to 15 degrees from 90 degrees straight up).

NOTE
If the inverter is installed in areas with high wind and sand, it is
recommended to install a windproof and sand barrier above the inverter.
3.1.6 Flammable substances
Do not install near flammable substances. Maintain a minimum distance of three meters
(10 feet) from such substances.
3.1.7 Living area
Do not install in a living area where the prolonged presence of people or animals is expected.
Depending on where the inverter is installed (for example: the type of surface around the
inverter, the general properties of the room, etc.) and the quality of the electricity supply, the
sound level from the inverter can be quite high.
3.2 Product Handling
Figure 3.4 Handles used to move the inverter shown circled in red - one per side
3.1.5 Air circulation
Do not install in small, closed rooms where air cannot freely circulate.
To prevent overheating, always ensure that the air flow around the inverter is not blocked.
Please review the instruction below for handling the inverter:
1. The red circles below denote cutouts on the product package.
Push in the cutouts to form handles for moving the inverter (see Figure 3.4).
2. Two people are required to remove the inverter from the shipping box. Use the handles
integrated into the heat sink to remove the inverter from the carton.
3. When setting the inverter down, do it slowly and gently. This ensures that the internal
components and the outer chassis do not take any damage.
3.1.4 Avoiding direct sunlight
Installation of the inverter in a location exposed to direct sunlight should to be avoided.
Direct exposure to sunlight could cause:
Power output limitation (with a resulting decreased energy production by the system).
Premature wear of the electrical/electromechanical components.
Premature wear of the mechanical components (gaskets) and user interface.

CAUTION:
If DC inputs are accidently reversely connected or inverter is faulty or not
working properly, it is NOT allowed to turn off the DC switch. Otherwise it
may cause DC arc and damage the inverter or even lead to a fire disaster.
The correct actions are:
*Use a clip-on ammeter to measure the DC string current.
*If it is above 0.5A, please wait for the solar irradiance reduces until the
current decreases to below 0.5A.
*Only after the current is below 0.5A, you are allowed to turn off the DC
switches and disconnect the PV strings.
* In order to completely eliminate the possibility of failure, please disconnect
the PV strings after turning off the DC switch to aviod secondary failures due
to continuous PV energy on the next day.
Please note that any damages due to wrong operations are not covered in
the device warranty.

3. Installation
CAN communication is supported between inverter and compatible battery models.
Please lead the CAN cable through the COM1 or COM2 port of the inverter and connect to
the BMS terminal with RJ45 connector.
When Lead-acid battery is used, battery temperature sensor needs to be connected to the
BMS terminal of the inverter.
Step 1. Take out the battery temperature sensor cable and lead through the COM1 or COM2
port of the inverter and connect the RJ45 connector to the BMS terminal.
Step 2. Fasten the temperature sensor ring onto the battery module. If no suitable fastening
terminal can be found on the battery module, the sensor ring can be attached to the positive
or negative pole of the battery module.
NOTE:
Before connecting CAN cable with the battery, please check whether the
communication pin sequence of the inverter and the battery match;
If it does not match, you need to cut off the RJ45 connector at one end of the
CAN cable and adjust the pin sequence according to the pin definitions of
both inverter and battery.

CAN Fail CAN Fail
1. Can failure is a failure of communication
between inverter and battery. Check cable
conditions. Check to ensure you have it
plugged in on the CAN port of the battery and
inverter. Check that you are using the right

Frequently Asked Questions
Q2: Why I have "BATName-Fail" Alarm on the inverter ?
A: Please check in the "Battery Setting->Battery Model" setting and confirm you selected the
correct battery option as the nameplate of your battery module.
Q3:Why I have "MET-SLT-Fail" Alarm on the inverter?
A: Please check in the "Meter Setting->Meter Type" setting and confirm you selected the
correct meter option corresponding to your smart meter.
Q4:Why the power values on the screen are fluctuating
