Dodgy battery backup systems

Grid-connected systems with battery backup

Due to the poor export tariffs being offered by many electricity retailers around Australia, many folk are turning to having some on-grid battery storage options so that they can store their valuable solar energy during the day to use at night – when they need it.

These kinds of systems are much more complex and have a lot more safety standards to comply with than a pure grid-connected solar PV system. Below is an example of a non-compliant system that breaches many of the requirements of the relevant standards: AS/NZS 3000; AS 4086; AS 2676; AS/NZS 4509.

Rapid environmental degradation of solar cable and connectors

These photos were provided to me anonymously – they show a three year old solar PV system in Australia that while being serviced had major problems with the cable and connectors.
