2.Safety Instructions
1. Permanent installation is required.
2. The electrical installation must meet all the applicable regulations and standards.
3. The inverter must be installed according to the instructions stated in this manual.
4. The inverter must be installed according to the correct technical specifications.
5. To startup the inverter, the Grid Supply Main Switch (AC) must be switched on, before
the solar panel's DC isolator shall be switched on. To stop the inverter, the Grid Supply
Main Switch (AC) must be switched off before the solar panel's DC isolator shall be
switched off.
.6.
CAUTION:
The PV array (Solar panels) 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 unauthorized .
CAUTION:
The surface temperature of the inverter can reach up to 75℃ (167 F).
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 disconnects that comply with the NEC
Article 690, Part II. All Solis 4G Mini Single Phase Inverters feature an integrated
DC switch.
CAUTION:
Risk of electric shock. Do not remove cover. There is no user serviceable
parts inside. Refer servicing to qualified and accredited service technicians.
PV module used with inverter must have an IEC 61730 Class A rating.
2.3 Notice For Use
The inverter has been constructed according to the applicable safety and technical
guidelines. Use the inverter in installations that meet the following specifications ONLY:
The inverter is operating without fault or alarm.

3.3 Keypad
3.4 LCD
There are four keys in the front panel of the Inverter(from left to right):
ESC, UP, DOWN and ENTER keys. The keypad is used for:
Scrolling through the displayed options (the UP and DOWN keys);
Access to modify the adjustable settings (the ESC and ENTER keys).
3. Overview
The two-line Liquid Crystal Display (LCD) is located on the front panel of the Inverter,
which shows the following information:
Inverter operation status and data;
Service messages for operator;
Alarm messages and fault indications.
.8.
To select a location for the inverter, the following criteria should be considered:
To avoid over heating ambient air temperature must be considered when choosing the
inverter installation location. Ginlong recommends using a sun shade minimizing direct
sunlight when the ambient air temperature around the unit exceeds 104°F/40°C.
Do not install in small closed spaces where air can not circulate freely. To avoid
overheating, always make sure the flow of air around the inverter is not blocked.
Exposure to direct sunlight will increase the operational temperature of the inverter and
may cause output power limiting. Ginlong recommends inverter installed to avoid
direct sunlight or raining.
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.

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 as it
will damage the inverter and even leads 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.
Please note that any damages due to wrong operations are not covered in
the device warranty.

4. Installation
5.1 Start the Inverter
To start up the Inverter, it is important that the following steps are strictly followed:
1. Switch the grid supply main Switch (AC) ON first.
2. Switch the DC switch ON. If the voltage of PV arrays are higher than start up voltage,
the inverter will turn on. The red LED power will light.
3. When both the DC and the AC sides supply to the inverter, it will be ready to generate
power. Initially, the inverter will check both its internal parameters and the parameters
of the AC grid, to ensure that they are within the acceptable limits. At the same time,
the green LED will flash and the LCD displays the information of INITIALIZING.
4. After 30-300 seconds (depending on local requirement), the inverter will start to
generate power. The green LED will be on continually and the LCD displays
GENERATING.
WARNING:
Do not touch the surface when the inverter is operating. It may be
hot and cause burns.
5.2 Stop the Inverter
To stop the Inverter, the following steps must be strictly followed:
1. Switch the Supply Main Switch (AC) OFF.
2. Wait 30 seconds. Switch the DC Switch OFF. All the LEDs of the inverter will be off in one
minute.
5. Start & Stop

6.5.12 Internal EPM Set
This section includes two functions related to the smart meter or smart sensor.
Please refer to section 4.3.7 or 4.3.8 for detailed connection diagrams.
Function 1: Internal Export Power Management Function
Inverters can work with a smart meter OR a smart sensor to dynamically limit
the export power of the system. Zero injection can be achieved.
Smart meter can be installed either on the grid side OR the load side.
Smart sensor can only be installed on the grid side.
.36. .37.
Function 2: 24 Hour Consumption Monitoring Function
Only applicable if Solis monitoring system is used.
Inverters can work with a smart meter to monitor the load consumption data
for the whole day and the data will be displayed on the Solis monitoring system.
Smart meter can only be installed on the grid side.
Please refer to below instructions for different user scenarios.
Scenario 1. Only Function 1 is required
Using a Smart Meter:
Step 1: Refer to Section 4.3.7 to connect the smart meter on the grid side or
load side.
Step 2: Select the corresponding meter model in Section 6.5.12.4
Step 3: Select the Section 6.5.12.1 Mode Select as Option 2(Meter in Load)
or Option 3 (Meter in Grid) accordingly.
Step 4: Configure the Section 6.5.12.2 to set the allowed backflow power.
Step 5: Configure the Section 6.5.12.3 to enable the failsafe function (If necessary).
Using a Smart Sensor:
Step 1: Refer to Section 4.3.8 to connect the smart sensor on the grid side.
Step 2: Select the Section 6.5.12.1 Mode Select as Option 5(Current Sensor).
Step 3: Configure the "CT Sampling Ratio" and "CT Link Test" if necessary.
Step 4: Configure the Section 6.5.12.2 to set the allowed backflow power.
Step 5: Configure the Section 6.5.12.3 to enable the failsafe function (If necessary).
Scenario 2. Both Function 1 and 2 are required
Using a Smart Meter:
Step 1: Refer to Section 4.3.7 to connect the smart meter on the grid side.
Step 2: Select the corresponding meter model in Section 6.5.12.4
Step 3: Select the Section 6.5.11.1 Mode Select as Option 3(Meter in Grid).
Step 4: Select the Section 6.5.3 24H Switch as "Enable".
Step 5: Configure the Section 6.5.11.2 to set the allowed backflow power.
Step 6: Configure the Section 6.5.11.3 to enable the failsafe function (If necessary).
Step 7: Configure the Solis monitoring system (Please refer to the manual of
monitoring device)
If customer does not want to enable the export power control function, please
change the "backflow power" to the max output power of the inverter in Step 5
OR simply select the mode as "consumption monitor" in Step 3 and skip Step 5-6.
