6 Types of Pellet Stove Battery Backup: Backup Time Chart

Pellet stoves are an efficient and eco-friendly way to heat your home, but they depend on electricity to operate. When the power goes out during a storm or an unexpected outage, your pellet stove will stop working—potentially leaving you without heat in the coldest months.

That’s where a battery backup system becomes a lifesaver. In this guide, we’ll explore everything you need to know about pellet stove battery backup systems, including the different options available and how to choose the best one for your needs.

Pellet Stoves and Their Power Requirements

Pellet stoves are powered by electricity, which drives key components such as the auger (which feeds pellets into the fire), the fans that circulate warm air, and the control panel. Despite their use of solid fuel (wood pellets), the reliance on electricity means they stop working during power outages.

Even though pellet stoves are energy-efficient, without electricity, the stove’s automation ceases, and so does your heat source.

Backup Time Chart for Pellet Stove

Backup Source	Power Capacity	Wattage Supported	Estimated Backup Time
Dedicated Pellet Stove Battery Backup	500–2000 Wh (varies by model)	300–500 watts	8–12 hours
Universal UPS (Uninterruptible Power Supply)	1000–3000 VA	300–500 watts	30 minutes – 2 hours
12-Volt Deep Cycle Battery Backup (with inverter)	100 Ah (1 battery)	300–500 watts	4–6 hours
Inverter Generator	1000–3000 watts	300–500 watts	8–24 hours (depending on fuel capacity)
Portable Power Station	300–2000 Wh	300–500 watts	4–12 hours
Solar Battery Backup System	1000–5000 Wh (with sufficient sunlight)	300–500 watts	4–24 hours (dependent on sunlight availability and battery size)

Choosing the Right Battery Backup for Your Pellet Stove

Selecting the right backup system involves considering your budget, the size of your pellet stove, and how long you need it to run during a power outage. A smaller battery backup might only give you a few hours of heat, while a larger generator or deep cycle battery could keep your stove running for days.

Make sure to check the power capacity (in watts) and runtime (in hours) of any backup system before purchasing. Additionally, think about whether you need a portable solution or a permanent installation.

Types of Pellet Stove Battery Backup Solutions

There are several types of backup systems you can use for your pellet stove, ranging from dedicated battery systems to more versatile power solutions.

Each has its pros and cons, and choosing the right one depends on your specific needs.

1. Dedicated Pellet Stove Battery Backup Systems

These systems are designed specifically to work with pellet stoves. They integrate seamlessly, providing backup power when the electricity goes out.

Brands like Harman and Quadra-Fire offer reliable systems that can keep your pellet stove running for several hours or even days, depending on the model.

2. Using a Universal UPS (Uninterruptible Power Supply)

A universal UPS system is an option many people already use for computers or other electronics to prevent sudden shutdowns. A UPS can also work with pellet stoves, providing short-term backup power.

The key is to find a UPS with sufficient wattage and battery capacity to handle the demands of your stove.

3. 12-Volt Deep Cycle Battery Backup

A deep cycle battery is a robust solution for longer power outages. Unlike a car battery, a deep cycle battery is designed to be discharged and recharged repeatedly without losing capacity.

You can pair it with an inverter to convert DC power to the AC power your pellet stove needs. This method provides a more extended run time, but it can be more complex to set up.

4. Inverter Generators as Backup for Pellet Stoves

Inverter generators are a versatile and reliable backup option. Unlike traditional generators, inverter generators produce cleaner, more stable power, which is essential for the sensitive electronics inside pellet stoves.

They’re also quieter and more fuel-efficient. Popular brands like Honda and Yamaha offer models ideal for pellet stoves.

5. Portable Power Stations for Pellet Stoves

Portable power stations are essentially large battery packs that can provide emergency power to various appliances, including pellet stoves.

These are quieter and more environmentally friendly than traditional generators but typically have shorter run times. Some newer models can even be charged via solar panels, making them a flexible solution for off-grid power.

6. Solar Battery Backup Solutions

If you’re looking for a green solution, a solar-powered battery backup system might be ideal. While solar energy can power a pellet stove, it requires a robust setup with solar panels, a charge controller, and batteries to store energy.

It’s an eco-friendly option, but it can be costly upfront and is highly dependent on the amount of sunlight available in your area.

What Happens When the Power Goes Out?

When the power goes out, pellet stoves shut down entirely. This can be more than just inconvenient, especially in frigid weather when the absence of heat can lead to freezing pipes, discomfort, and even health risks.

Additionally, any leftover pellets in the burning chamber might continue to smolder and release smoke if the stove is not properly vented, posing a potential safety hazard.

Why You Need a Battery Backup for Your Pellet Stove

A battery backup system ensures that your stove can continue running during a power outage. Not only does this help you maintain comfort and warmth, but it also prevents malfunctions and overheating that can occur when the stove unexpectedly stops.

Moreover, the ability to keep your stove running during outages is crucial for safety, particularly for families with children, elderly members, or individuals with health concerns.

Installation Tips for Pellet Stove Battery Backup Systems

Installing a battery backup system can be straightforward or complex, depending on the type you choose. Many dedicated systems or UPS units simply plug into your pellet stove.

However, if you’re using a deep cycle battery or inverter generator, you may need to do some additional wiring or hire a professional.

Maintenance of Battery Backup Systems

Once you have your battery backup system in place, regular maintenance is essential to keep it running smoothly. Deep cycle batteries should be charged periodically, even when not in use.

Generators require fuel and oil checks, while UPS systems should be tested to ensure the battery is still holding a charge.
