The Solis EPM 5G is a device that allows you to adjust export values to satisfy local network 
regulatory requirements. 

 

 

General Notes 

 

 

Do not place 

communication cables with DC and AC cables in the same conduits or 

trunking as this may influence the normal communications.

 

 

Ensure that the communication 

wires between the inverter and EPM are properly 

connected as 

in the manual. (refer to system wiring diagram) 

 

The EPM should always be connected to the first inverter on the RS485 bus if multiple 
units are installed and the other inverters must be daisy chained. 

 

The  secondary  current  for  the  CT  should  be  5A  and  recommended  class  0.5CT  for 
higher accuracy on the measured values. 

 

The load must be switched off before disconnecting CT as this will open circuit the 
secondary of the CT and may cause damage to CT, EPM or injury. 

 

Date & Time setting 

must be the same on the EPM and the Inverters.
