Where to Put the Battery: Heat, Ventilation and Safety

Where you put a battery affects how long it lasts and how safe it is.

1. Temperature

• Heat ages batteries faster. Keep them out of direct sun and away from hot tin walls.
• Lithium batteries usually can't charge below about 0°C, and some have heaters.
• Check the battery's operating temperature range.

2. Ventilation

• Lead-acid batteries can release hydrogen while charging. They need ventilation.
• Lithium batteries don't vent in normal use, but still need airflow for heat.

3. Fire safety and rules

In Australia, home battery installs have rules about where batteries can go, including clearances from doors, windows, exits and living areas. Your installer will know the current requirements. Avoid bedrooms, living spaces and escape paths.

4. Practical things

• Keep it close to the inverter so the heavy DC cables are short.
• Leave room to see the display, switch the isolator and work safely.
• Keep it off the floor where water can reach it, and away from vehicles.

5. Quick summary

• Cool, dry, shaded and ventilated.
• Close to the inverter.
• Follow the battery maker's and installer's rules.

In Australia, any work on 240V AC wiring, including connecting an inverter, battery or solar system to a switchboard or fixed wiring, must be done by a licensed electrician.
