If the inverter is not to be installed immediately, storage instructions and environmental
conditions are below:
Use the original box to repackage the inverter, seal with adhesive tape with the
desiccant inside the box.
Store the inverter(s) in a clean and dry place, free of dust and dirt.
Keep box(es) away from corrosive materials to avoid damage to the inverter enclosure.
Inspect packaging regularly. If packaging is damaged(wet, pest damage, etc),
repackage the inverter immediately.
Store the inverter(s) on a flat, hard surface - not inclined or upside down.
After long-term storage, the inverter needs to be fully examined and tested by qualified
service or technical personnel before using.
Restarting after a long period of non-use requires the equipment to be inspected
and, in some cases, the removal of oxidation and dust that has settled inside the
equipment will be required.
To select a location for the inverter, the following criteria should be considered:
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.
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.
Figure 5.1 Recommended Installation locations
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.
NOTE:
Nothing should be stored on or placed against the inverter.

5.2 Mounting the Inverter
Figure 5.3 Inverter wall mounting
Refer to figure 5.4 and figure 5.5. Inverter shall be mounted vertically.
The steps to mount the inverter are listed below.
1. Refer to Figure 5.4, the holes for expansion bolt based on the hole diameter of bracket
(M10*70) , using the percussion drilling with the 10mm drill need to stay vertically on
the wall. And the drill hole must be vertically on the wall. And all drill holes' depth is 60mm.
2. Make sure the bracket is horizontal. And the mounting holes (in Figure 5.4) are marked
correctly. Drill the holes into wall at your marks.

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.

6.1 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 initialize. 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.
6.2 Stop the Inverter
6. Start & Stop
To stop the inverter, it is mandatory that the steps below are followed in the exact order outlined.
1. Select "Grid Off" in the Advanced Setting of Inverter LCD.
2. Turn off the AC Switch between Solis inverter and Grid.
3. Wait approximately 30 seconds (during this time, the AC side capacitors are dissipating
energy). If the inverter has DC voltage above the start-up threshold, the red POWER
LED will be lit. Switch the DC switch OFF.
4. Confirm all LED's switch OFF (~one (1) minute).
CAUTION
Although the inverter DC disconnect switch is in the OFF position and all
the LED's are OFF, operators must wait five (5) minutes after the DC power
source has been disconnected before opening the inverter cabinet. DC
side capacitors can take up to five (5) minutes to dissipate all stored energy.
