Please do not connect the “N” of AC output to the “N” of AC input on SIES.
Otherwise, the AC output RCD will trip and SIES will not work properly.
The neutral output of Energier Pro bi-directional inverter is automatically connected to earth if
no external source is available. Once external AC source is exist, the ground relay will
be on”
OPEN” status.
4.7.5 Connect the cables of programmable AC outputs
SIES system is designed with two programmable AC outputs for smart load control. Please refer to
Section 2.10 for details. To set up and use the programmable AC outputs, please refer to Section
6.4
Choose the proper cable size (refer to Section 4.3), connect the power cables of appliances to
the programmable AC outputs in terminal block of Smart Box.
Connectors are marked as “L” (Line), “N” (Neutral) and “PE” (Earth). Making sure they are tightly
screwed. .
4.7.6 Connect battery voltage sensor
Normally there is voltage drop in the connection between Energier Pro and battery bank, which leads
to reduction of charging efficiency. The Battery Voltage Sensor (VS) is therefore recommended to
eliminate this voltage drop and improve the charging efficiency. To connect a battery voltage sensor,
please follow the below steps:
Pull the VS cables (positive and minus) through hole in the front cover of Energier Pro and
connect it to the interface of Energier Pro
which marked “Voltage Sensor”. Please refer to
following Figure 23.
The minus (-) of voltage sensor should be connected to the minus (-) of service battery, and the
positive (+) of voltage sensor should be connected to the positive (+) of service battery. Wrong
connection will damage the Energier Pro bi-directional inverter and is out of warranty.
Please connect the minus (-) and positive (+) cables of Voltage Sensor to the terminals of battery
respectively (Figure 23).
