3. PV Connection: Please install separately a DC circuit breaker between inverter and PV modules. The recommended of DC breaker is 600V/25A. It’s very important for system safety and efficient operation to use appropriate cable for PV module connection. To reduce risk of injury, please use the proper recommended cable size as below:

• Before connecting all wiring, please take off bottom cover by removing 3 screws as shown below.

Mounting the Unit

Notice
Consider the following points before selecting where to install:

• Mount on a solid surface
• Do not mount the inverter on flammable construction materials.
• For proper air circulation to dissipate heat, allow a clearance of approx. 20 cm to the side and approx. 50 cm above and below the unit.
• The ambient temperature should be between 0°C and 55°C to ensure optimal operation.
• The recommended installation position is to be adhered to the wall vertically.

Steps to mounting the unit

1. Step1. Use the wall-mounting bracket as the template to mark the position of the 4 holes, then drill 8 mm holes and make sure the depth of the holes is deeper than 50mm.
2. Step2. Install the expansion tubes into the holes and tight them, then use the expansion screws (packaged together with the expansion tubes) to install and fix the wall-mounting bracket on the wall.
3. Step3. Install the inverter on the wall-mounting bracket and lock the inverter using the security screws.

Battery Connection
Battery Power Cable Connection
Note: for lead acid battery, the recommended charge current is 0.2C( C to battery capacity)

1. Please follow below steps to implement battery connection:
2. Assemble battery ring terminal based on recommended battery cable and terminal size.
3. Connect all battery packs as units requires. It’s suggested to connect at least 200Ah capacity battery for SNA5000 WPV.
4. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts are tightened with torque of 2 ~3Nm. Make sure polarity of the battery is correctly connected and ring terminals are tightly screwed to the battery terminals.

Lithium Battery Connection
If choosing lithium battery for SNA5000 WPV, please make sure the battery BMS is compatible with Luxpower inverter. Please check the compatible list in the Luxpower website.

Please follow below steps to implement lithium battery connection

1. Connect power cable between inverter and battery
2. Connect the CAN or RS485 communication cable between inverter and battery. If you do not get the communication cable from inverter manufacturer or battery manufacturer, please make the cable according to the PIN definition
3. Lithium battery configuration, in order to communicate with battery BMS, you should set the battery type to “Li-ion” in Program “03” by LCD and choose the right battery brand (for details, please check the LCD setting chapter), users can also choose the battery type and brand by monitor system.

2.4 CT
To measure the power imported from and exported to the grid, a pair of Cts must be installed at the service entry point in or near the main service panel. We standardly supply 2 CT for one inverter,”External Grid CT” function is off by default, and if you need inverter to export power to compensate the grid loads, you can set “External Grid CT” function to Enable” state. Please refer to section 4.4 LCD Settings for detected setting info.

CT Port Pin definition
The CT interface for CT connection is a RJ45 port

Please refer to the connection diagram to determine the correct position of the Grid CT and securely attach it to the L wire at the service entry point in the main service panel. The arrow on the CT should point towards the inverter. (*** Incorrect installation of the CT may result in the display showing incorrect information, and the inverter features may not function properly.) If the CT is installed in the wrong direction, you can change the CT direction on your inverter by selecting “CT Direction Reversed” in the Advanced Tab. There is no need to make any physical changes.

CT Clamp Ratio
The inverter support 3 ratios of CT clamp- 1000:1 , 2000:1 and 3000:1 . The CT ratio of the CTs in the accessory bag is 3000:1. If you are using a 3rd party CT, please ensure the CT ratio is one of them, and select the correct CT ratio setting in the inverter monitor page or on the inverter LCD.

AC Input/Output Connection

CAUTION

• There are two terminal blocks with “IN” and “OUT” markings. Please do NOT disconnect input and output connectors.
• Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause utility short-circuited when these inverters are worked in parallel operation.

Please follow below steps to implement AC input/output connection

1. Before making AC input/output connection, be sure to open DC protector or disconnected first.
2. Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3 mm.
3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws. Be sure to connect PE protective conductor first.

• Users can connect the generator output to ECO Hybrid inverters. GEN input terminal.
• The generator will be automatically started when battery voltage is lower than the cut-off value or there is charge request from BMS. When voltage is higher than AC charge setting value, it will stop the generator
• Battery will get charged when the generator is turned on, and the generator is bypassed to AC output to take all loads .

• The system will use AC first if there is both utility input and generator input.
• The capacity of the generator is recommended It is supported to parallel 2~3 PCS inverter with single phase in single phase parallel system and three phase parallel system to charge battery with Generator! And it is depends on the load performance of the generator too.

Dry Contact Signal control

The Dry port(NO2,COM2) could be used to deliver signal to external device when battery voltage reaches warning level. The GEN port(NO1,COM1) could be used to wake-up the Generator and then the generator can charge the battery.
