3 Product storage and installation
3.1 Product storage:
If the machine won’t be installed immediately, please store the inverter vertically
according to the package instruction, and in the dry place where can avoid direct
sunshine, dust and high temperature.
3.2 Installation
Here introduce the re uirements while choosing the installation site and doing wiring.
As every site has its specificity, here we do not cover the detailed installation steps,
but offer general guidance and methods so that installer can handle in different
situations.
Note:
 Installation site must be guided by the licensed professional engineer authorized by the
company;
 Whiling doing the electrical connection, first connect the grounding and ensure all
switches are open before the connection is unfinished;
 Inverter should be installed according to the instruction and local standards;
 When connecting the battery, please remove the rings, bracelets, watches, bracelets and
other metal objects. In case of electrolyte leakage or damage to the battery, you must
replace the battery, and put it into sulfuric acid corrosion resistant containers and disposed
of in accordance with local regulations. If skin touches the electrolyte, please immediately
wash with water.
Warning!
To ensure the safety of device and people, please let professionals do
the installation.

3.3 Installation site
When selecting an inverter installation space, you should note the following
re uirements:
1) Put the inverter in the suitable position with good ventilation, at least 150mm ambient space around the
vent and fan;
2) The inverter needs to be put in the clean and dry indoor room (Environment
temperature:0-40 degree; Relative humidity: 5%~90%; ideal operating temperature is 25
degree). If room temperature reaches 40 degree, it’s suggested to add air-conditioner or
other ventilation device;
3) If altitude is more than 1000m, please use it with less power (de-rating);
4) The system shall be installed in a suitable location which indoor walls meet the
load-bearing capacity (according to the convenience of the user and should ≥1.6 m), like
the installation space dimensions.
Mounting hole dimensions Fixed hole depth drawings Product installation drawings
3.4 Cable connections
When selecting external wiring cables, cable current capacity and system overload
capacity should be considered, as well as environment temperature and physics support.
The following table is a proposal to cable selected, engineer should refer to the relevant
local standards and under table to make a comprehensive selection. The length of the

17
connecting cable is generally 2 to 10 meters; long cable will cause the voltage decrease, the
corresponding cable cross-sectional area size should be increased.
