Testing and Commissioning Services

Scope of Work

Elite Energy & Engineering has the ability to conduct testing and commissioning services according to (62446-1 IEC and IEC TS 62446-3) standards following the National and International regulations for Low Voltage and Medium Voltage sides.

Visual inspection of the following components:

1. PV modules ( compatibility with the data sheet).
2. Inverters (compatibility with the data sheets and grid connection standards).
3. PV mounting structure (Robustness and Fixation).
4. DC cabling and connection (compatibility with the SLD).
5. AC cabling and connection (compatibility with the SLD and Grid connection application).

Tests of all DC circuit(s) forming the PV array:

1. Earth Resistance (Ω).
2. Earth Continuity for inverters and structures.
3. Insulation Resistance for DC cables.
4. Polarity Test.
5. String Open Circuit Voltage Test.
6. String Short Circuit Current Test.

Tests of all AC circuit(s) and power quality

1. AC Cabling Insulation Test.
2. Disconnection & Re-connection Time for inverters.
3. Power Quality Test.
4. Voltage Magnitude.
5. Output Current.
6. Power Factor.
7. Total Harmonic Distortion (THD).
8. Total Output Power & Energy.

Tests of Medium Voltage (MV) circuits

1. Transformers Test.
2. MV cables hi-pot and Very Low Frequency (VLF) Test.
3. Switch Gear Test.
4. Ring Main Unit (RMU) Test.
5. Earth Resistance Testing.
6. Visual Inspection.
