2.2 Mounting the Unit
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.

2.3 Battery Connection
2.3.1 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.
2.3.2 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.

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

2.5 AC Input/Output Connection
CAUTION!!
- There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input and
output connectors.
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.
4. Insert AC output wires according to polarities indicated on terminal block and tighten terminal screws.
Be sure to connect PE protective conductor first.
5. Make sure the wires are securely connected.
- 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.

2.6 PV Connection
Please follow below steps to implement PV module connection:
1. Remove insulation sleeve 10 mm for positive and negative conductors.
2. Check correct polarity of connection cable from PV modules and PV input connectors.
3. Connect positive pole (+) of connection cable to positive pole (+) of PV input connector. Connect negative
pole (-) of connection cable to negative pole (-) of PV input connector.
4. Make sure the wires are securely connected.
5. Finally, after connecting all wiring, please put bottom cover back by screwing two screws as shown below.
2.7 Generator Connection
N→Neutral (blue)
L→LINE (brown or black)
1. Before making Generator connection, be sure to open DC protector or disconnected first.

All lux units can work with generator.
Battery will get charged when the generator is turned on, and the generator is bypassed to AC output to
take all loads .
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

1. SONAR can work as traditional off grid inverter or as a hybrid inverter. When disable PV&AC
Take load Jointly, it will work as a traditional off grid inverter, otherwise it will work as a hybrid
2. Working as a traditional off grid inverter. In this situation, inverter either use (solar+battery) to take
load or use AC take load. Related settings
AC First: During the setting time, system will use AC to take load first, use solar power to charge the battery.
If the battery is full, solar power may be wasted. When out of the setting time, system will use battery and
solar to take load until battery voltage/SOC is lower than cut off voltage/SOC
3. Working as a hybrid inverter. Related settings
3.1 AC First: During this setting time, system will use AC to take load, use solar power to charge the battery
first. If there is extra solar power, extra solar power will take the load. When out of the setting time, system
will use solar and battery to take load first until the battery voltage/SOC is lower than On Grid EOD settings,
then it will use AC to take the load.
3.2 Export to Grid/Export Power percent: Users can also enable export function, it is allowed and set export
power percent
3.3 AC Charge function Disable: The system will not use AC to charge the battery(except Li ion BMS set
force charge flag )
According to Time: During the setting time, system will use AC to charge the battery until battery full and
battery will not discharge during the setting time.
According to Battery Voltage: During the setting time, system will use AC to charge the battery if battery
voltage is lower than AC Charge Start Battery Voltage and will stop when Voltage is higher than AC Charge
End Battery Voltage. And battery will not discharge during the setting time.
According to Battery SOC: During the setting time, system will use AC to charge the battery if battery SOC
is lower than AC Charge Start Battery SOC and will stop when Voltage is higher than AC Charge End Battery
SOC. And battery will not discharge during the setting time.
