2. Installation Instructions
2.1 Precautions for Installation
Please read this Manual carefully to familiarize yourself with the installation steps before installing.
Take great care when installing the battery. Wear protective goggles when installing the lead-acid liquid battery.
Once contacting the acid solution of battery, please rinse with clear water in time.
Avoid placing any metal object near the battery against short-circuiting.
Acid gas may be generated when the battery is charged so as to ensure good ventilation of surroundings.
When the cabinet is installed, it is necessary to leave enough space around the inverter for heat dissipation; Do
Not install the inverter and the lead-acid liquid battery in the same cabinet, so as to prevent the acid gas
generated when the battery works from corroding the inverter.
Only the type of battery conforming to this inverter can be charged.
Virtual junctions and corroded wires may cause great heat, melt the insulation of wire, burn the surrounding
material, and even cause fire. Therefore, it is necessary to ensure that all connectors are tightened, and wires
are preferably fixed with ties to avoid loose connectors caused by shaking of wires during mobile applications.
The connection wire of the System shall be selected according to the current density no more than 5A/mm

.
After the power is turned off, there is still high voltage inside the inverter. Please Do Not open or touch the
internal devices, and Do Not carry out relevant operations until the capacitor is discharged.
Please Do Not install the inverter in any flammable and explosive environment.
No reverse polarity is allowed for the battery input of this product, otherwise, it is easy to damage the
equipment or cause any unpredictable danger.
The mains input and AC output are high voltage, so please Do Not touch the wire connector.
When the fan is working, Do Not touch it to prevent injury.
For the input power of load equipment, it is required to confirm that this Inverter is the only input equipment
and it is forbidden to use it in parallel with any other input AC power source so as to avoid damage.
2.2 Wiring Specification and Circuit Breaker Selection
The wiring and installation methods must comply with national and local electrical specifications.
Recommended PV Array Wiring Specification and Circuit Breaker Selection: since the output current of PV array is
affected by the type of PV module, connection mode and illumination angle, the minimum wire diameter of PV array
is calculated according to the short-circuit current of PV array; please refer to the short-circuit current value in the
specification of PV modules (the short-circuit current of PV modules is unchanged when they are connected in series;
if in parallel, the short-circuit current will be the sum of the short-circuit current of all parallel modules); the short-
circuit current of the array cannot exceed the maximum PV input current.
