NECA Technical Update - Battery Energy Storage System (BESS) inverters

Important information from NECA

NECA and the Electrical Regulatory Authorities Council (ERAC) have advised that some brands of Battery Energy Storage System (BESS) inverters are non-compliant with Australian standards.

These types of inverters are causing final subcircuit Residual Current Device (RCDs) and Residual Current Breaker with Over-Current (RCBOs) to not operate and are bypassing the Multiple Earthed Neutral (MEN) in the electrical installation.

For more information in relation to electrical installations and solar / small scale generation and documents on this subject, please visit the ERAC website.
