Mains, solar or battery
How the gate gets its power shapes the whole job. Some motors run on mains, some on solar, and many on a battery that either one keeps charged. Merlin's Slide 600 can run on mains power, solar power or low voltage, and Merlin also makes rural solar gate openers.
Battery backup keeps a gate working through an outage. CENTSYS says its D5-Evo sliding motor carries two 7Ah batteries for that, and its V-Series SMART swing motors run on a 7.2Ah battery that can also take a solar supply.
Sliding or swing
Merlin calls slide gates the space-saving option for wide entries and compact driveways, because they run along a track and park beside the fence. A swing gate needs a clear arc of ground to open into, which is easier on a flat block than on a steep one.
Swing motors come as one operator per leaf. The V-Series is a piston drive with a 400mm or 500mm stroke, sold as a single or double kit, and Merlin's swing range includes the Swing L300, Swing A200 and Swing LR 500.
Wiring an electric gate in Queensland
Running mains power to the gate is electrical work, and Queensland law says only a person whose electrical work licence covers it may do it. Some trades hold a restricted electrical licence, but it does not authorise installation work.
Queensland's Electrical Safety Office suggests checking the electrical contractor licence number on its online Electrical Licence Search before agreeing to the work.
Standards and sensing
AS/NZS 60335.2.103:2024 sets the safety requirements for household electric drives on gates, doors and windows that move horizontally or vertically. Ask what the motor does when it meets something in its path: CENTSYS says the D5-Evo detects obstructions, and Merlin's myQ app will not run a gate without Safety IR Beams. Keep children and pets away from a moving gate.
Handy to know before they call
- What the gate is made of, roughly how long it is, and whether it slides or swings
- Whether there is power near the gate, or a sunny spot for a panel
- How the driveway slopes where a swing gate would open
- Whether you want a keypad or camera, which ATA sells as add-ons, or phone control
Gates around the Sunshine Coast
Hinterland properties
On acreage around Maleny, Montville and Eumundi, a solar motor avoids trenching power down a long drive. Check how much winter sun the panel spot gets.
Storm months
Sunshine Coast Council says cyclones can occur from December to April. A motor with battery backup keeps the gate usable if a storm cuts the power.
Bushfire country
After the 2019 fires at Peregian and Cooroibah, it is worth knowing how your gate behaves without mains power, so you are never stuck behind it when you need to leave.
What we would do
If you are leaning toward solar, stand where the panel would go on a winter afternoon, not a summer noon. Trees and the house throw longer shadows in June, and a panel in shade by mid afternoon may not keep a busy gate charged.
