electric shock.
1.1.2 Protection for PV Array
When install the PV array in the daytime, use light-proof material to cover the PV array, or, under the
sunshine, the PV array will generate high voltage. Once touch the PV array by accident, it may cause
electric shock or endanger human life.
There is deadly high voltage between the positive and negative of the PV array.
During installing, ensure that the connection between inverter and PV array is completely
disconnected and set warning marks at the disconnection to avoid reconnecting by accident.
1.1.3 Anti-Static Protection
The static electricity generated by human bodies may damage the electrostatic-sensitive components
on boards. Before touching the sensitive component, please wear anti-static rings and well connect
the other end of the anti-static rings to ground.
1.1.4 Grounding Requirements
High leakage risk! The inverter must be grounded before electrical connection. The ground terminal
must be connected to earth.
lWhen installing, connect the grounding wire first; when dismantling, the grounding wire must be
removed at last.
lIt is prohibited to damage the grounding conductor.
lThe device must be connected with protection earthing permanently. Before operating, please
check the electric connection and ensure the device has been connected to earth reliably.

IV430E REV. 00 Issued: 2020/06/03 User Manual SOLEIL SRT 1.5-6k 1ph Pag. 12 of 56 +FR

DC switch
DC switch (as shown in Figure2-5,1) is the connection switch of inverter and PV array. When the
inverter works normally, the DC switch must be ON. During installation and wiring, the DC switch
must be OFF. Before maintenance, the DC switch must be OFF for 20 minutes, and measure the
voltage of DC busbar by multimeter, only when the voltage less than 10V, the maintenance can be
done.
when maintenance or wiring, the DC switch must be disconnected.
2.3 Work Principle
The inverter connects with PV array input and tracks the maximum power point of the PV array, and
then converts the DC power into single-phase AC power by inverter circuit. It also provides surge
protection at DC and AC side, as shown inFigure2-6, Figure2-7.
