ANGLEC advises the general public to take great caution when connecting and using at home solar systems.
- The installation of Solar systems MUST be done in compliance with the National Electrical Code (NEC).
- Main Disconnection point and or the isolation between ANGLEC and the Solar supply MUST be operational/functional and tested regularly.
- NEVER have a solar connection done by anyone other than a qualified electrician.
- To prevent the dangerous backflow of electricity the recommended solar inverters should meet the IEEE 1547 or UL1741 standards. If these standards are not listed or mentioned on the solar units, they should not be used as they pose the risk of dangerous back feeding to the grid in the event of an outage.
Improper installation and use of solar systems can result in dangerous, even fatal levels of electricity feeding back into ANGLEC’s main power lines, posing a severe risk to your family, the public and ANGLEC’s crews/recovery efforts. Backfeeding from residential solar systems can pose several dangers if not properly managed. The potential risks associated with backfeeding include but are not limited to:
- Electrical shock: Backfeeding occurs when the solar system sends excess electricity back into the electrical grid. If the grid is not properly isolated, it can energize power lines that are supposed to be de-energized during maintenance or repair work. This can put utility workers or anyone coming into contact with the power lines at risk of electrical shock if they assume the lines are not live.
- Fire hazards: Improperly backfeeding electricity can cause fire hazards. If the solar system is not correctly connected to the electrical system or lacks appropriate safety mechanisms, it can overload circuits, leading to overheating, melting of wires, or even electrical fires. Faulty wiring, improper grounding, or incompatible components can all contribute to fire risks.
- Damage to equipment: Backfeeding electricity can damage equipment or appliances connected to the electrical system. If there are voltage fluctuations or surges due to improper backfeeding, sensitive electronics may be at risk of damage. This includes household appliances, electronics, and other devices that rely on a stable power supply.
- Legal and regulatory issues: In many jurisdictions, backfeeding electricity into the grid without proper authorization or equipment may violate electrical codes, regulations, or utility interconnection agreements. Such unauthorized backfeeding can result in legal consequences and penalties.
To mitigate these dangers, it is crucial to follow electrical codes and guidelines specific to your region and consult with qualified professionals during the installation and interconnection process of residential solar systems. Additionally, using appropriate safety mechanisms such as grid-tie inverters with anti-islanding features, disconnect switches, and properly designed wiring systems can help minimize the risks associated with backfeeding.
