Each week, we look at questions people are asking across search, AI, forums, and the gate industry and answer three worth knowing.
1. Should I Power My Automatic Gate With Solar or 115V?
Both can work well. The better choice depends on the property, the operator, and how much work the gate system is expected to do.
For many battery-powered DC gate operators, the batteries are what actually power the motor. The difference is how those batteries are kept charged. They may be maintained by a charger connected to 115V power, by solar panels, or in some systems by either method.
That means choosing solar versus 115V isn't simply about choosing one kind of motor over another.
When 115V makes sense
If utility power is reasonably close to the gate, 115V is often the simplest and most dependable way to keep the system charged.
It becomes especially attractive when the entrance has:
- High daily cycle counts
- Keypads or access-control equipment
- Vehicle loops and detectors
- Electric or magnetic locks
- Heaters or other higher-draw accessories
- Network equipment
- Heavy gates or demanding operating conditions
A busy HOA or commercial entrance can consume considerably more energy than a residential driveway opening a few times each day.
The downside may be getting power to the gate. If the entrance is hundreds of feet from the nearest electrical source, trenching, conduit, wire, permits, and electrical work can become a significant part of the installation cost.
When solar makes sense
Solar can be an excellent solution when running 115V to the gate would be difficult or expensive.
It is especially useful for:
- Long driveways
- Remote entrances
- Ranches and agricultural properties
- Low- to moderate-cycle residential gates
- Locations with good, unobstructed sunlight
But simply adding a solar panel does not automatically make a gate a good solar application.
The system still has an energy budget.
The panel needs to produce enough energy to replace what the gate and its accessories use. Battery capacity needs to carry the system through nights and periods of poor sunlight. Shade from trees, buildings, or seasonal changes in the sun can also have a major effect on performance.
With solar, more capacity is usually better
When selecting a solar package, it generally makes sense to choose more charging and battery capacity whenever the application and budget allow.
Larger-wattage solar panels and higher-capacity batteries can provide more reserve for cloudy weather, higher cycle counts, and unexpected increases in usage.
Some manufacturers even offer higher-capacity or XL versions of certain gate operators from the factory, with larger solar and battery packages already configured for applications that need more reserve.
It is usually better to have some extra capacity than to design a solar system that is barely large enough under ideal conditions.
Be careful with intercoms and other accessories
Solar can become more complicated once additional equipment is added.
Intercoms, telephone entry systems, and some other access-control devices often cannot simply be powered from the gate operator's control board.
The operator may provide 24V accessory power, but the device you want to connect may require a different voltage, more amperage than the board can safely supply, or enough continuous current that it could overload the operator's accessory output.
In those cases, the accessory may need a separate power supply.
That can change the entire solar design. The gate operator itself may work perfectly on solar while the intercom or another accessory still requires its own source of power.
So when planning a solar entrance, don't calculate only what the gate operator needs. Look at everything that will need electricity at the gate.
Is solar cheaper?
Sometimes. Not always.
Solar may save the cost of trenching electrical service to a distant entrance, which can make it the obvious choice.
But solar shouldn't be selected simply because it sounds easier or because you want to avoid bringing power to the gate. A system with too little panel capacity, too little battery capacity, too much shade, or too much daily usage can become frustrating very quickly.
The better question is:
How much energy will this entire gate system use, and what is the most practical way to keep it powered?
For a lightly used remote gate, the answer may be solar. For a heavily used entrance with several accessories, 115V may be the better long-term solution.
2. Why Does My Automatic Gate Stop Halfway or Reverse?
A gate that stops partway through its travel or suddenly reverses is often reacting to something the operator believes is wrong.
That doesn't automatically mean the motor is bad.
Start by paying attention to when and where the problem happens.
Does it stop in the same place every time?
If the gate consistently stops or reverses at roughly the same point, look closely at what is happening at that part of the gate's travel.
Possible causes include:
- A bad roller or damaged section of track
- A hinge that begins binding at a certain angle
- A sagging gate
- A physical obstruction
- Incorrect limits
- A position or encoder problem
- Increased resistance at one part of the travel
- A linear screw-drive actuator that is dry or needs lubrication
A slide gate, for example, may move normally until it reaches a damaged section of track. A swing gate may operate smoothly through most of its arc and then begin binding as it approaches the open or closed position.
On linear swing-gate operators that use a screw-drive mechanism, lack of lubrication can also increase resistance as the actuator travels. If the screw becomes dry or begins binding, the operator may slow down, stop, or reverse because it sees the additional load as an obstruction.
Lubrication requirements vary by operator, so use the lubricant and service procedure specified by the manufacturer rather than simply applying whatever grease is available.
Safety devices can also stop or reverse the gate
A photoeye, safety edge, or other monitored entrapment-protection device can tell the operator not to continue moving.
A dirty or misaligned photoeye, damaged wiring, intermittent connection, or activated safety edge can cause a gate to stop, reverse, or refuse to continue.
Wind can create a similar symptom on some gates. A large solid swing gate can act like a sail. On a windy day, the operator may encounter considerably more resistance than it does under normal conditions.
Don't overlook the batteries
Low battery voltage can also show up as a gate that starts moving normally and then stops under load.
A battery may appear to have acceptable voltage while the operator is idle but drop significantly once the motor begins drawing current. That is why battery condition is not always obvious from simply looking at the system or checking voltage with no load.
Loose connections, charging problems, or failing batteries can create similar intermittent symptoms.
What if it reverses immediately?
If the gate begins moving and quickly reverses, pay particular attention to:
- Safety inputs
- Obstruction detection
- Mechanical resistance
- Force or current sensing
- Limits or position sensing
- Anything physically interfering with the gate
One thing you should not do is simply keep increasing the operator's force setting until the problem disappears.
If the gate has become harder to move, a safety device is being triggered, or the operator is detecting abnormal resistance, increasing the force can hide the symptom without fixing the cause.
A properly operating gate should move freely, and the operator should not have to fight the gate through its travel.
3. Will Cloud-Based Gate Access Still Work if the Internet Goes Down?
Sometimes yes, sometimes no.
The important question is what part of the system depends on the internet.
A cloud-based access-control system may use the cloud for administration, reporting, mobile apps, visitor management, and communication with remote users. But that does not necessarily mean the gate has to contact the cloud every time someone presents an authorized credential.
Many systems use a local controller at the gate or building. That controller can store authorized users, credentials, schedules, and access rules locally.
If the internet goes down, those previously authorized credentials may continue working because the local controller can still make the access decision.
What may stop working during an internet outage?
Depending on the system, you may temporarily lose functions such as:
- Remote gate opening through an app
- Live activity reporting
- Adding or deleting users remotely
- Changing schedules from the cloud
- Receiving real-time notifications
- Visitor-management functions
- Video or intercom features that rely on an internet connection
Meanwhile, a locally stored card, fob, keypad code, or other credential may continue operating normally.
But that behavior varies by manufacturer and system design, so it should never simply be assumed.
What about smartphone access?
This is where the distinction becomes especially important.
Some mobile credentials can communicate locally with a reader using Bluetooth or another local technology. Others depend on an internet connection or cloud service to authorize the request.
Likewise, pressing Open Gate from an app while you're miles away obviously requires some form of communication between your phone and the entrance.
If the site's internet connection is down and there is no cellular backup, that remote command may not reach the gate even though local credentials continue working.
The network equipment matters too
A connected gate system includes more than the access controller.
It may depend on:
- Modem
- Router
- Network switch
- Cellular gateway
- Wi-Fi access point
- PoE equipment
- Local controller
- Power supplies
A perfectly functioning access controller can appear offline because a router or network switch lost power.
For critical entrances, network backup, battery backup, cellular redundancy, and an alternative method of entry may all be worth considering.
Ask one question before buying
If you are considering a cloud-based gate access system, ask:
What still works locally if the internet connection disappears?
The answer should be clear before the system is installed.
Cloud access can make it dramatically easier to manage users and entrances, but a well-designed system should also account for what happens when the connection to the cloud is temporarily unavailable.
