• Mount on a solid surface.
• Install this inverter at eye level in order to read the LCD display clearly.
• For proper air circulation to dissipate heat, require a clearance about 50 cm to the side and 80 cm above and below the unit.
• The ambient temperature should be between 0°C and 40°C to ensure optimal operation.
• The recommended installation position is to be adhered to the wall vertically.
• Be sure to keep other objects and surfaces as shown in the diagram to guarantee sufficient heat dissipation and to have enough space for removing wires.

DC Wiring Suggestion
It is suggested to keep battery bank as close as possible to inverter. battery cable length lm is suggested. Please find following minimum wire size. If DC cable longer than 1 m, please use thicker battery cables to bear power current going though.

Please connect cable size thicker enough, or connect several combined thin cables together to be same strong. Battery bank should be kept dose to inverter; The shorter and thicker cables, the better the system performance.
Please follow battery connection steps below: Assemble battery ring terminal. Connect all battery packs as units requires. Battery cable and terminal size suggestion: It’s suggested to connect at least 100Ah capacity battery pack for 1KW-3KW models, at least 200Ah for 4KW-6KW models.
NOTE: Please only use sealed lead acid battery or sealed GEL/AGM lead-acid battery. Insert the ring terminal of battery cable into inverter to battery connector, make sure the bolts are tightened with torque of 2-3Nm. Pay special attention to battery back and inverter are connected rightly, also ring terminals are tightly screwed to the battery terminals.

 WARNING:
Shock Hazard Installation with special care is required due to high battery pack voltage.
 CAUTION!! Do not place anything between the flat part of the inverter terminal and the ring terminal. Otherwise, overheating may occur.
CAUTION!! Do not apply antioxidant substance on the terminals before terminals are connected tightly.
CAUTION!! Before making the final DC connection or closing DC breaker/ dis-connector, be sure positive (+) must be connected to positive(+) and negative(-) must be connected to negative(-).

AC Input/Output Connection
CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between inverter and AC input power source. This will ensure inverter can be disconnected safely during maintenance and fully protected from over current of AC input. Suggestion AC breaker: 30A for 1KW-3KW, 40A for 4KW-6KW. CAUTION!! Please don’t connect the output wring to “Grid” terminal or connect the grid wring to the “Load” terminal.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It’s very important to use appropriate cable for Grid connection for system safety and efficient operation . To reduce injury risk, please use the proper suggested cable size as below. AC Wiring We recommend using 10-5AWG wire to connect AC terminal block. There are 3 different ways to connect AC wire to terminal block.
