Earthing and bonding cables
- Earthing and bonding cables shall have a minimum cross-sectional area of 6mm2
- Where positive and negative live conductors exceed 6mm2, the earthing and bonding conductors shall have a minimum cross-sectional size conductor. equal to the positive and negative live conductors.
This means – PV cables are 4mm2, 6mm2, 10mm2 or thicker. One may not install earthing conductors less than 6mm2; Installations with 1.5mm2, 2.5mm2 or 4mm2 earthing conductors are illegal.
PV Array system
The voltage rating of the PV array system shall be the maximum open-circuit array voltage at the lowest operating temperature.
This means – Let us say a charge controller (MPPT) has a maximum input voltage of 450 volts and a PV module is say 50 volts. This voltage is listed at STC (Standard Test Conditions) which is 25°C. Voltage increases as it gets colder.
Thus, installing 9 PV modules @ 50 volts which is equal to 450 volts would not be possible.
Apart from the Standard, the MPPT will also be damaged.
Verification and Testing
Every user or lessor of an EGI shall have a valid CoC for every such installation. A CoC shall only be valid when it is accompanied by a test report in the format as specified in this document and SANS 10142-1.
This means – That, apart from the specific requirements in SANS 10142-1, when you install a PV system you are required BY LAW to obtain a NEW CoC for the part of the Installation affected by the changes.
