ATM Power Requirements: Can Batteries or Solar Power Run an ATM?

Do you need to know ATM power requirements for events and off-grid locations? Powering an ATM isn’t always as simple as plugging it into the wall. 

Whether you’re deploying an ATM at a dedicated full-time location, planning a temporary event, or looking for backup power during outages, many people ask the same question: Can an ATM run on batteries or solar power?

The short answer is yes. However, the right solution depends on usage, location, and expectations. This article explains how much power ATMs use, what battery and solar setups realistically require, and how to choose the best option for full-time locations versus temporary events.

How Much Power Does an ATM Use?

One of the most common misconceptions is that ATMs use very little electricity. In reality, ATM power requirements are closer to those of a small office workstation than a phone charger. While exact numbers vary by manufacturer and model, you can expect typical ATM power consumption to fall within general ranges. 

There are two power states: idle and dispensing. A typical ATM, like the Genmega 2500, draws roughly 25-100 watts when idle and between 150–300 watts when dispensing or printing during a transaction. Large or illuminated screens, toppers, receipt printers, cash recyclers and outdoor or through-the-wall (TTW) ATMs will see higher average power draws. 

Dispensing and printing lasts only a few seconds. So for most ATMs, 99%+ of the time is spent idle, meaning the majority of the energy draw is from the idle state. When considering a power source, know that any battery or solar solution must handle both continuous power draw and short bursts of higher demand.

Powering ATMs with Batteries: What’s Required

Battery power is often the foundation of off-grid or backup ATM setups. However, not all battery systems are the same. There are some factors you need to consider before selecting the most appropriate battery system.

Battery Power for Full-Time Dedicated ATM Locations

For permanent or semi-permanent installations without reliable grid power, battery-only systems require careful planning.

First, consider the total runtime required: 8, 12, 24+ hours? What’s the expected daily average transaction volume? What’s the battery capacity (measured in watt-hours or kilowatt-hours)? Will there be temperature control and ventilation?

Keep in mind that small consumer uninterruptible power supply (UPS) units typically used for computers are not sufficient for running an ATM for extended periods. Most full-time setups require a large battery bank (often lithium-based), a high-quality inverter (pure sine wave is critical for ATMs), and a method for recharging (solar or generator).

Lithium batteries are increasingly preferred over lead-acid. This is due to higher efficiency, longer lifespans, faster charging times, and reduced maintenance.

Battery Power for Temporary Events and Pop-Ups

Events such as festivals, fairs, sporting events, and pop-up retail locations have different requirements.

Overall, battery power works well for events. Operating windows are usually short (4–12 hours). There are predictable transaction spikes. And there is no need for permanent installation.

Therefore, common solutions include portable power stations, custom battery banks with inverters, and hybrid battery+generator setups.

High-traffic events may still exceed the capacity of many “plug-and-play” battery units, especially if the ATM is used continuously. Operate by this rule of thumb: The busier the event, the more likely a generator or hybrid system is needed.

Can Solar Power Run an ATM? The Reality of Solar Powered ATMs

Solar power is one of the most frequently misunderstood ATM power options. While solar can support an ATM, it rarely works as a standalone solution.

Solar panels do not directly power ATMs in most cases. Instead, they charge batteries during daylight hours, extend battery runtime, and reduce reliance on generators or grid power.

To estimate solar needs, account for ATM power usage, number of operating hours per day, average daily sunlight (“sun hours”), and seasonal and weather variability.

Simply, daily ATM energy needs ÷ average sun hours = required solar capacity.

Because ATMs must operate reliably regardless of cloud cover or nighttime use, solar almost always requires a battery bank.

The Most Practical Option: Solar + Battery Hybrid Systems

For off-grid or semi-remote locations, hybrid solar-and-battery systems are often the most reliable solution.

Batteries provide consistent power while solar panels recharge batteries during the day. This combination reduces generator runtime or fuel costs and improves uptime.

Hybrid systems work especially well for rural or remote ATM locations, seasonal venues (campgrounds, marinas, tourist areas), disaster recovery or emergency deployments, and environmentally focused businesses.

While upfront costs are higher, hybrid systems often deliver better long-term reliability than battery-only setups.

FAQs About Battery and Solar ATM Power Requirements

Can a portable power station run an ATM?

Some high-capacity portable power stations can run an ATM temporarily, but many are not designed for continuous high loads or transaction spikes. Always verify wattage limits and inverter quality.

How long will a battery last during heavy ATM usage?

High transaction volume significantly shortens runtime. Continuous dispensing can drain batteries much faster than idle operation.

Can one solar system power multiple ATMs?

It’s possible, but system size increases quickly. Each additional ATM adds substantial load and complexity.

A 100W solar panel generates about 400–600 Wh/day (real-world conditions). That’s only 20–25% of one ATM’s daily use, so fully sustaining a 3-day, 24/7 setup would require at least 3×100W panels, ideally 400W of solar input, to keep the power station topped off during the day.

Is battery or solar power allowed by ATM manufacturers?

Most manufacturers specify strict power requirements. Improper power delivery may void warranties or cause hardware issues.

What happens if power drops mid-transaction?

Power interruptions can cause transaction failures, cash errors, or machine downtime. Therefore, stable power is critical.

Choosing the Right ATM Power Strategy

There is no one-size-fits-all solution for meeting ATM power requirements without traditional electricity. You can follow these general guidelines based on your specific needs and expectations:

• Permanent off-grid ATM: Large battery bank + solar + backup generator
• Temporary events: Portable battery systems or battery-generator hybrids
• Backup power only: High-capacity UPS or short-term battery support

The right choice depends on transaction volume, location, reliability expectations, and budget. However, the next section offers a couple of “plug-and-play” templates you can use to swap in your own specs (transactions, hours, wattage, battery size, solar input) without needing to be an engineer!

Real-World ATM Power Scenarios You Can Model

The easiest way to estimate ATM power requirements for events or off-grid locations is to think in scenarios, not averages. An ATM may be “idle” most of the time, but short bursts of activity—screen brightness, cash dispensing, receipt printing, and communications—drive real power needs.

Here are two common scenarios that you as a deployer may find useful as templates.

Scenario 1: Event-Based ATM (Transaction-Driven Load)

Use this model if you’re deploying an ATM at a festival, fair, concert, or pop-up event and want to estimate power needs based on expected usage.

Assumptions (example):

• ATM activity: 50 transactions per day (or ~15 transactions per hour during a 3–4 hour peak window)
• Idle power draw: 25 watts
• Active transaction power draw: 120 watts
• Average transaction duration: 60 seconds
• Operating time: 12 hours

Step 1: Calculate idle energy.

• 25 W × 12 hours = 300 Wh/day

Step 2: Calculate transaction energy.

• 50 transactions × 1 minute = 50 minutes of activity
• 120 W × (50 ÷ 60 hours) ≈ 100 Wh/day
• Estimated daily energy usage ~400 Wh per day

In practice, this means that a 500 Wh battery would comfortably cover a single day with margin. A 1,000 Wh battery would provide multi-day coverage or insurance against heavier-than-expected usage. 

A small portable solar (100–200 W) can offset idle draw during daylight but usually won’t fully recharge in one day during an event. So, for short events, most of your energy is spent keeping the ATM awake rather than dispensing cash. Planning around idle draw prevents surprise shutdowns late in the day.

Scenario 2: Genmega 2500 ATM (Off-Grid Deployment)

Use this model if you’re deploying a specific ATM model in a semi-permanent or unattended off-grid location. Use the specifications of your ATM model to get a closer estimation.

Assumptions (example):

• ATM model: Genmega G2500
• Average idle draw: 25–30 watts
• Peak active draw: 120–150 watts
• Location usage: Low volume (≤40 transactions/day)
• Target uptime: 24/7

Step 1: Estimate daily energy consumption.

• Idle load: 27 W × 24 hours ≈ 650 Wh/day
• Transaction load: ~100 Wh/day
• Total: ~750 Wh/day

Step 2: Check battery size.

• 1,000 Wh battery → ~1.3 days runtime
• 2,000 Wh battery → ~2.5 days runtime
• 3,000 Wh battery → ~4 days runtime (recommended for weather variability)

Step 3: Check solar size (to remain energy-neutral):

• Daily energy need: 750 Wh
• Average usable sun: 4–5 hours/day

Required solar:

• 750 Wh ÷ 4.5 hours ≈ 170 W minimum

Opt for a 300–400 W solar array to recharge batteries after cloudy days, offset inverter losses, and account for seasonal variation. This setup supports continuous off-grid operation, multi-day autonomy during poor weather, and reduced maintenance visits for battery swaps. 

You can adapt these scenarios to your own deployment. Customize by adjusting transactions per day or hour, idle wattage (check your ATM’s spec sheet), operating hours, desired battery life (1 day vs. 3-5 days), and local solar conditions.

ATM power planning is about energy over time, not peak wattage alone. Once you understand your idle load and transaction profile, sizing batteries and solar becomes straightforward and far more reliable.

Recommended Equipment to Meet Your ATM Power Requirements

Here, we recommend some equipment to help ATM deployers like you choose actual power stations or kits. We include options for both event-style temporary setups and longer-term off-grid locations. These selections span from ~1 kWh portable units (good for short events) up to larger solar-ready systems for multi-day/off-grid use:

For Short Events and Temporary Deployments

These 1 kWh-class units are light enough to carry and sized appropriately for portable ATM setups or short event power needs (with solar recharging if a panel is paired):

The Jackery Solar Generator 1000 V2 has ~1,070 Wh capacity and ~1,500 W output. It includes solar panel support and multiple ports making it a solid all-around choice for event deployers.

The Anker SOLIX C1000 Gen2 Portable Power Station is another option with ~1,024 Wh, two 100 W solar panels included in some bundles, and a good balance of power and recharge speed.

Finally, the Dabbsson DBS1000 Pro Solar Generator has ~1,024 Wh with a robust inverter and solar support which is nice for slightly heavier loads or UPS-style backups.

Your bonus event kit option is the Jackery Explorer 1000 Plus Solar Generator Kit. It combines a ~1 kWh station with two 100 W panels for better solar input and faster recharge during multi-day events.

For Permanent/Off-Grid ATM Installations

For deployments where you expect continuous operation or need multi-day autonomy and robust solar recharging, these larger units offer more capacity and power headroom:

The Pecron E2000LFP Portable Power Station offers ~1,920 Wh capacity with ~2,000 W output. It’s a solid choice for powering an ATM plus comms/lighting for longer off-grid periods.

The Jackery Explorer 2000 V2 Solar Generator has ~2,000 Wh and ~2,200 W output in a relatively portable footprint which works well for unattended locations.

The OUKITEL BP2000 PRO Portable Power Station offers ~2,048 Wh with a strong inverter and high solar input capability. This is a good option for multi-day or high-reliability installs.

And the Yoshino K20SP21 Solid-State Portable Solar Generator offers ~1,326 Wh with a strong 2,000 W output and multiple ports. This option works well for mixed loads and higher-draw components like routers or lighting.

Additional Tips

Try to match capacity to uptime needs.

For short events, ~1 kWh (1,000 Wh) is often enough with a couple hundred watts of solar charging. For multi-day or unattended sites, aim for ~2 kWh+ and scalable solar input so you don’t run flat during cloudy stretches. If solar panel pairing, most power stations support MPPT solar input, but panel size matters—more watts = faster recharge. 

And in terms of UPS behavior, if the ATM needs uninterrupted power (even through swaps), choose units with UPS passthrough support or devices designed for seamless transfer.

Understanding ATM Power Requirements

Battery and solar power can absolutely play a role in ATM deployments, but only when designed realistically. Understanding ATM power requirements, transaction behavior, and environmental factors is essential to avoiding downtime and costly mistakes.

If you’re considering an off-grid or temporary ATM installation, working with professionals who understand both ATM hardware and power systems can save time, money, and frustration in the long run.
