6 Installation
6.1 Attentions
Read all the installation instructions carefully in the manual before installation.
Be very careful when installing the batteries. When installing the open-type lead-acid battery, please
wear eye protection and rinse with clean water in time for battery acid contact.
Keep the battery away from any metal objects, which may cause a short circuit of the battery.
Loose power connections and corroded wires may result in high heat that can melt wire insulation,
burn surrounding materials, or even cause a fire. Ensure tight connections and secure cables with
clamps to prevent them from swaying while moving the inverter.
The DC input voltage must strictly be following the parameter table. Too high or too low DC input
voltage will affect the inverter's normal operation and damage it. The surge voltage shall be less
than 20V@12V system, less than 40V@24V system, and less than 80V@48V.
Select the connection cables according to the current density of 3.5A/mm
2
or less.
Avoid direct sunlight and rain infiltration when installing it outdoor.
After turn off the power switch, do not open or touch the internal component immediately. Related
operations are performed after 10 minutes.
Do not install the inverter in a harsh environment such as humid, salt spray, corrosion, greasy,
flammable, explosive, or dust accumulation.
The AC output is of high voltage, do not touch the wiring connection to avoid electric shock.
To prevent injury, do not touch the fan while it is working.
6.2 Wire size and circuit breaker
The wiring and installation methods must conform to the national and local electrical code requirements.
