Descriptions of Labels

DANGER!
Lethal danger from electrical shock due to the inverter
• Only operate the inverter when it is technically faultless. Otherwise, electric shock or
fire may occur.
• Do not open the enclosure in any case without authorization from SolaX.
Unauthorized opening will void the warranty and cause lethal danger or serious
injury due to electric shock.

WARNING!
Risk of personnel injury or inverter damage
• During operation, do not touch any parts other than DC switch and LCD panel.
• Never connect or disconnect the AC and DC connectors when the inverter is
running.
• Turn off the AC and DC power and disconnect them from the inverter, wait for 5
minutes to fully discharge the voltage before attempting any maintenance, cleaning
or working on any circuits connected.
• Make sure that the input DC voltage ≤ Maximum DC input voltage of the inverter.
Overvoltage may cause permanent damage to the inverter, which is NOT covered by
the warranty.

CAUTION!
• Keep children away from the inverter.
• Pay attention to the weight of the inverter. Personal injuries may be caused if not
handled properly.

NOTICE!
• If an external RCD is required by local regulations, check which type of RCD is
required for relevant electric codes. It is recommended to use a Type-A RCD with
the value of 300 mA.
• All the product labels and nameplate on the inverter shall be maintained clearly
visible.

3. Battery connection steps

Communication Connection

• CAN1/CAN2/DRM/OFF port connection

2. Cable connection steps

• Please ground the GND terminal of Meter1 if you want to connect a meter.

2. Pin definition for Meter

3. Cable connection steps

• COM port connection

1. Pin definition for COM

_B(out)

NOTE: Pin 3 cannot be short-circuited with any other pin in case of the possible damage
of an inverter.

• You can control the inverter and other external devices through the COM interface.
  Professional users can use pins 4 and 5 to realize data acquisition and external control
  functions. The communication protocol is Modbus RTU. For details, please contact us.

2. Situation of external equipment controlled by the inverter

• BMS port connection

1. Pin definition for BMS

Item BMS
Pin 1 2 3 4 5 6 7 8
Pin Definition EXT_NTC GND GND BMS_CANH BMS_CANL X BMS_485A BMS_485B

• The communication port on the lithium battery must be consistent with the definition of
  pins 4, 5, 7 and 8 above.

2. For BMS cable making, please refer to the cable connection steps of the COM port. Then
insert the well connected cable into the BMS port of the inverter and screw it tightly.
