Unpacking and Inspection
Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should have received the following items inside the package:
Before connecting all wirings, please take off the cover of the bottom by removing the two screws as shown below.
Mounting the Unit
Consider the following points before selecting where to install:
NOTES: SUITABLE FOR MOUNTING ON CONCRETE OR OTHER NON-COMBUSTIBLE SURFACE ONLY.
Install the unit by screwing two screws as shown in the diagram. It’s recommended to use M4 or M5 screws.
CAUTION: For safety operation and regulation compliance, it’s requested to install a separate DC over-current protector or disconnect the device between battery and inverter. It may not be necessary to disconnect the device for some applications, however, it’s requested to have over-current protection installed. Please refer to the typical amperage in the table below as required fuse or size of the breaker.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It's very important for system safety and efficient operation to use appropriate cable for battery connection. To reduce risk of injury, please use proper cables and suitable size of terminal recommended below.
Recommended battery cables and size of terminal:
Please follow the steps below to implement the battery connection:
Connect all battery packs as below chart.
Insert the battery wires flatly into battery connectors of inverter and make sure the bolts are tightened with torque of 2 Nm in clockwise direction. Make sure polarity at both the battery and the inverter/charge is correctly connected and conductors are tightly screwed into the battery terminals. Recommended tool: #2 Pozi Screwdriver
To firmly secure wire connection, you may fix the wires to strain relief with cable tie.
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 the inverter can be securely disconnected during maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 40A for 3KVA.
CAUTION!! There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input and output connectors.
WARNING! All wiring must be performed by the qualified personnel.
WARNING! It's very important for system safety and efficient operation to use appropriate cable for AC input connection. To reduce risk of injury, please use the recommended cable size as below.
Suggested cable requirement for AC wires
Please follow below steps to implement AC input/output connection:
Then, insert AC output wires according to polarities indicated on terminal block and fasten the terminal screws. Be sure to connect PE protective conductor first.
Make sure the wires are securely connected.
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker betwand PV modules.
WARNING! All wiring must be performed by a qualified personnel.WARNING! It's very important for system safety and efficient operation to use appropriate module connection. To reduce risk of injury, please use the recommended cable size as below.
PV Module Selection:
When selecting proper PV modules, please be sure to consider the parameters below:
Please follow the steps below to implement PV module connection:
After connecting all wirings, please put the bottom cover back by fixing two screws as shown below.
