Clenergy SPH Installation and Operation Manual
Step2: Prepare the electric grid (AC utility) connection
1.
Verify that the electric grid voltage is 220V to 250V AC single-phase at 50Hz
or 60Hz. This information is available from the electricity provider.
2.
Ensure that the AC supply wire to the inverter is disconnected from the
electric grid. For example, the fuse is removed or the circuit breaker is open.
Verify with an AC voltmeter that there is no voltage between the Line and
neutral AC wire and between each AC wire and earth ground.
3.
The table provided suggests minimum wire sizes for the AC cable. Ensure
the selected wire conforms to local and national wiring codes.

For SPH15 SPH20 SPH30 SPH40, connect AC wires as follows:
Disassemble the AC output female socket.
Connect AC wires to connection socket as indicated:
Strip the wire sheath and conductor insulators the minimum amount
necessary to insert the wires into the connection pins.
Insert Line wire to
L
, Neutral wire to
N
and Ground wire to pin
Fully tighten the wire clamp screws in each connection pin.
Assemble the socket again. Insert the whole socket into the inverter.
Twist the coupling ring to receptacle on inverter. Make sure it is perfectly
matched and tightly fastened.
