116 SI80H-60H-OffGrid-IA-en-11 Installation Manual
7.24.2 Starting the Off-Grid System
Requirement:
☐ All off-grid inverters must be switched on.
1. If no functional test has been completed yet, switch off all miniature circuit-breakers and switch-
disconnectors for the AC sources in the sub-distributions.
2. Press the start-stop button on the off-grid inverter
and hold it until you hear a signal.
or
Press and hold the button on the Sunny Remote
Control until you hear a signal.
☑ The inverter LED is glowing green on every off-grid inverter.
7.24.3 Testing the Battery Current Sensor
If a battery current sensor is present, you must carry out the following steps.
Requirement:
☐ All miniature circuit-breakers in the AC sub-distribution must be switched off.
1. Connect the miniature circuit-breaker of one load in the AC sub-distribution.
2. Measure the battery current with a current clamp.
3. Switch to installer mode (see Section 7.5).
4. Select the 120.06 TotBatCur parameter and read off the value.
☑ The value is positive and corresponds to the measured value.
✖ Is the value not positive or does it not correspond to the measured value?
The value is negative because the poles of the measuring cables of the battery current sensor
are reversed.
• Install the battery current sensor correctly (see section 6.29).
The value does not correspond to the measured value because the incorrect battery current
sensor type has been set.
• Set the correct battery current sensor type (see Section 7.13"Commissioning the Battery
Current Sensor",page101).
