Installation Prerequisites
Ensure that the installation location meets the following conditions:
Y The building is designed to withstand earthquakes Y The location is far from
the sea to avoid salt water and humidity, over 3280.84 ft/1000 m Y The floor
is flat and level Y There are no flammable or explosive materials, at a
minimum of 2.95 ft/0.9 m Y The ambience is shady and cool, away from heat and
direct sunlight Y The temperature and humidity remain at a constant level Y
There is minimal dust and dirt in area Y There are no corrosive gases present,
including ammonia and acid vapor Y Where charging and discharging, the ambient
temperature ranges from 32°F/0°C to 113°F/45°C
In practice, the requirements of battery installation may be different due to
enviroment and locations. In that case, follow up the exact requirements of
the local laws and standards.
Note!
The Greenworks battery module is rated at IP65 and thus can be installed
outdoors as well as indoors. However, if installed outdoors, the battery pack
shall not be exposed to direct sunlight and moisture.
Note!
If the ambient temperature exceeds the operating range, the battery pack will
stop running to protect itself. The optimal temperature range for operation is
14°F/-10°C to 122°F/50°C. Frequent exposure to harsh temperatures may
deteriorate its performance and lifetime.
Note!
For the first installation, the interval among manufacture dates of battery
modules shall not exceed 3 months.

Step 2: (1) Place the assembled Transverse Plate and Base Support on the wall, look the cylindrical plastic bubble spirit level on the Transverse Plate. If the bubble isn’t in the center, slightly bow it to the horizontal. (2) Then determine the position of holes. (3) Mark it with a pen. (4) Remove it and drill the four holes (at least 3.54 in./90 mm) by Drill (Ø 0.47 in./12 mm for concrete wall, or Ø 0.31 in./8 mm solid wood wall).
Step 3: (1) Place the assembled Transverse Plate and Base Support to the wall (or solid wood stub); (2) Attach the Expansion Screw to the holes but be sure not to tighten; (3) Check whether the bubble spirit level is horizontal; (4) Hammer Expansion Screws with a rubber mallet (except solid wood wall), and tighten it with torque wrench.

Commissioning
Steps for commissioning are shown as follows: Press the left side door panel
Open the air switch’s guard and toggle switch, to ensure that the inverter
does charge to the battery Press the right side door panel

Black Start: Press the POWER button and hold it for 20 sec; release the button
after the four SOC indicators flash blue alternately. But, we do not recommend
the use of Black Start as it may cause the port to be charged, resulting in an
electric shock.
If the batteries have not been used for more than 9 months, these batteries
must be charged to at least SOC 50 % each time. For the first installation,
the interval among manufacture dates of battery modules shall not exceed 3
months. If a battery is replaced or added for capacity expansion, each
battery’s SOC should be consistent. The max. SOC difference should be between
±5%. If users want to increase their battery system capacity, please ensure
that the SOC of the existing system capacity is about 40%. The manufacture
date of the new battery shall not exceed 6 months; in case of exceeding 6
months, please charge the new battery to around 40%.
The equipment can support capacity expansion. There are two circumstances in
case the user wants to increase a battery module: 1. For floor mounting,
remove the inverter before increase of battery module; 2. For wall mounting,
if the distance from the equipment to the ground is enough, do not remove the
inverter; otherwise, the inverter shall be removed.
