In order for the system to work correctly, a load sensing current transformer MUST be installed. Alternatively, an external Modbus
meter may be used. Meter installation is outside of the scope of this guide. Please refer to the full user manual if meter measurement
is needed.
The current transformer must be connected to the inverter using the supplied 4 way CT/Meter connector shown on page 1 of this
guide - The White wire (S1+) must be connected to pole 1 of the connector. the Black wire (S2-) must be wired to pole 2.
The current transformer must be installed as shown above. The arrow on the transformer must point towards the incoming utility
meter. The inverter must be able to see 100% of the load or it will not work correctly
