Technical Specifications
Note: The output voltage and current of the PV module depend upon several factors such as the
number, size and temperature of the cell, and is influenced by the intensity of sunlight. The highest
voltage of a PV module is output when the cell is at the lowest temperature and circuit is open. The short
circuit current must less than or equal to the maximum DC input current of the micro-inverter.
Please make sure the output voltage and current of the PV module match with the Meikai micro-inverter.
A list of compatible PV modules is maintained on the Meikai website (http://www.meikai-cn.com).
WARNING: The maximum open circuit voltage of the PV module must not exceed the
specified maximum input voltage of the Meikai Micro-inverter.
WARNING: The maximum open circuit voltage of the PV module must not exceed the
specified maximum input voltage of the Meikai Micro-inverter.
Electrical Connection
The inverter is compatible with RCD and RCM.
The DC component may produce electricity; as a result, a residual current operated protective (RCD) or
monitoring device (RCM) will be used for protection in case of direct or indirect contact, only Type B
RCD/RCM is allowed to be connected to the supply side of the product.

If you choose the models without DC switch an external disconnection device should be used. It should
be multi-pole switch-disconnector(all poles disconnected simultaneously), which has been approved
according to standard IEC/EN 60947-3. The rated current should be between 20A and 25A. Besides,
AC breaker is also needed between inverter and Grid. The rated current should be over AC output
current, One branch AC breaker should be over 15A.
