Safety & battery storage systems

To ensure the safety of your family, friends and employees, make sure your battery storage system is operating safely.

Over charging and discharging

The life and efficiency of a battery can be affected by a poor battery control system.

A battery management system or battery control system should be designed to suit the type of battery used. Over charging and discharging can result in a temperature rise. This can lead to reduced battery life or in worst-case scenarios, battery explosions.

Your battery storage system will be set up to ensure that charging and discharging is appropriate, so do not change any of the settings as this could put your battery at risk.

Some battery systems have alarms on them to indicate if something is wrong – it might be a low state of charge, over charge or temperature issue. Any alarm warning should be reported to your installer.

Leaking and corrosion

If there is any leakage from your battery storage system this is extremely serious ... shut your system down and call your installer. Make sure you clean any spills up as they may be corrosive or have environmental consequences.

Seek immediate advice from the manufacturer or installer if you find leaking or corrosion in your battery storage system.

Poor maintenance

Poor maintenance may reduce the life and efficiency of the battery storage system faster than expected. Ensure suitably qualified battery installers maintain your system.

Your battery storage system should have instruction manuals and a maintenance schedule set out by the manufacturer. You must follow these to ensure the warranty is not void and to maintain safety standards.

Back-up systems

There are safety requirements for back-up systems to make sure they don't export energy back into the grid during a blackout. This is important in ensuring workers repairing the electricity network are not exposed to a safety risk from power being supplied from your premises.

Your battery storage system will need suitable labeling in your main switchboard to ensure that your electricity distributor (eg. Ergon Energy Network) and emergency services personnel (ie. fire brigade) are aware of a back-up system on your premises.

Shutting down

Every battery storage system must have a shut-down procedure that allows you to shut it down if something goes wrong, or you need to isolate the system.

If you need to turn the power off to your house, having a battery storage system means you now have two possible power sources and you may need to isolate the power at two locations.

You can install a change-over switch for some battery storage systems, useful if any part of your system needs to be sent away to get fixed.

Keep your system locked up

Your battery system should be kept locked at all times as battery terminals can be lethal – even if the battery bank is only 48 volts. Labeling in your main switchboard and the board which your system is connected to is important.
