Pricey Pickings: How Much Does a Whole-Home Battery Backup System Cost?

Your home is guaranteed to be where you spend the most time. This is the central hub for your entire family to eat, rest, have fun, and be together. That’s why it’s important to always keep your home fully powered up.

After a long day, your body isn’t the only thing that needs charging. Your home needs to be a space of reliable and consistent power to stay warm, functioning, and prepared. That’s why Mango Power has the ideal whole-home battery backup system for you.

What Is a Whole-Home Battery Backup System?

A whole-home battery backup system provides power for your home during blackouts or grid failures. These systems generally use electricity from the grid to charge or can make use of solar energy from installed solar panels.

A battery backup system is in contrast to a generator -which uses fuel to run. Generators can be a lot more expensive, noisy, and difficult to maintain. However, a battery backup system offers sustainable, cheap, and consistent energy.

A battery backup generator offers reliable power that can maintain all your essential appliances and equipment throughout your home. This ensures that your family stays warm, safe, and powered up.

There are multiple reasons that a battery backup system is the best option for your home. However, some might be hesitant to leap into sustainable energy just yet – understandably so.

Before choosing a power system for your home, you have to consider a few things - including:

Renewable energy has often been unfairly dismissed as a much too expensive option when it comes to power supply solutions. However, renewable power has effectively proven to save you money.

Although, some renewable energy sources will be a bit heavier on the wallet than others. This depends on several factors.

Factors Affecting the Cost of a Whole-House Battery Backup System

When seeking out a whole-home battery backup solution, your price range might fluctuate according to the following factors:

Battery Size

Naturally, the larger the battery, the more you would pay for the system. Your battery size will be dependent on how much energy you want to store for later. However, the cost per kilowatt-hour (kWh) of electricity storage decreases as the battery size increases. This means that investing in a bigger battery saves you from having to add costly supplementary power later on. 

The U.S. Energy Information Administration confirmed that the average US customer uses around 886 kWh of electricity per month – which is about 30 kWh per day. To maintain this level of electricity consumption, you’d need a backup battery system size of 30 kWh just to run your house as normal for one day during a blackout.

Power Output Capacity

While they seem similar, the battery storage and power output capacity are not the same. The storage capacity refers to the maximum amount of energy that your battery can hold at any given time - typically measured in watt-hours (Wh) or kilowatt hours (kWh). The power capacity, on the other hand, is the maximum amount of electricity your battery backup system can output at once.

The power capacity will tell you the type of appliances you can run on the backup system. Calculate your power output needs by following these steps:

  1. Identify the wattage requirements of your appliances. 
  2. Convert volts/amps to watts. Note: Volts (V) x Amps (A) = ​​Watts (W)  
  3. Count the running watts of your appliances. 
  4. Add the highest starting wattage to the running wattage total.
  5. The final amount is the total starting watts you need from your backup power system.

Starting and Running Watts of Typical Household Appliances


The setup your power backup system uses will also add to the bottom line of your bill. A standalone backup power supply that needs to just be plugged in will be a lot cheaper than an integrated system.

Charging Options

Backup power supplies are only useful as long as they’re fully charged. During extended blackouts, it’s difficult to rely solely on grid-charging backup power solutions. 

Having a backup power system with multiple charging options will increase your ability to stay powered up.  For example, you can easily charge the Mango Power E using several different methods – including:

  • 3000W maximum generator charging
  • 2000W maximum EV station charging
  • 2000W maximum solar charging

Electricity Generation

Choosing to supplement your backup power from multiple sources also improves your electricity generation. This makes it a lot easier to give your entire home consistent power.

While all these factors play a role in your choice, it can still be difficult to choose the right battery backup system for your home.

Which Whole-House Battery Backup System Is Right for You?

When choosing a power backup system, the price isn’t the only thing to stop and consider. Your home deserves only the best energy solution. Looking at these elements might also help you in choosing the best power backup solution:

Expected Lifespan

While the cheapest option might be the most attractive, you have to think long-term when it comes to your home’s power. Your home battery backup solution should be able to last you for a long time before needing to be replaced. 

Battery Chemistry and Efficiency

Your battery choice will determine how long the power system can be used before needing to be recharged. Previously lead acid batteries were used but proven to be less efficient. Most modern power supply solutions will make use of Lithium-ion and LFP batteries which have a longer lifespan and quicker recharging rate.

Mango Power systems make use of world-class CATL lithium-ion phosphate batteries that seamlessly outperform other chemistries. The battery’s unique self-healing technology allows for a greater number of charging, discharging, and recharge cycles throughout the battery's lifespan.


Lead acid battery systems require a lot more maintenance – including adding distilled water every 2 to 4 weeks, never being discharged below 50% capacity to prevent damage, being stored in well-ventilated areas, and being unable to function in extreme cold or heat. 

Contrastingly, LFP batteries are much more adaptable and require almost no maintenance.


A warranty gives you peace of mind and quality assurance. Your energy backup system should have a long-standing warranty that ensures that you can trust the brand and the device not to falter or fail without any backup.
