How to Choose the Right Home Backup Battery System？

For every homeowner, having the right backup battery system is not only crucial for ensuring basic electricity needs during power outages but can also help save on energy bills. This is especially true if you live in areas prone to frequent power outages. A backup battery system offers a reliable power source and can significantly reduce your electricity costs, particularly during peak electricity pricing periods. So, how do you determine the right backup battery system for your home's energy needs? Let’s explore the key steps in selecting the ideal backup battery system.

1. Understand Your Power Consumption

The first step in determining the required backup battery capacity is understanding how much electricity your home uses on a monthly basis. You can either refer to your electricity bill or use a power meter to measure the energy consumption of each appliance. Here are the typical power consumption figures for common household appliances:

• Refrigerator: Standard refrigerators consume around 100 to 350 watts, while high-end models can consume between 350 and 780 watts.
• Oven: A standard electric oven consumes approximately 3000 watts, with high-end models reaching up to 5000 watts.
• Air Conditioner: Depending on the size and type, air conditioners typically consume between 1000 and 5000 watts.
• Other Appliances: Smaller devices such as computers (50 to 300 watts) and TVs (100 to 500 watts) consume relatively less power, while lighting systems using LED bulbs typically consume very little energy.

By calculating the average power consumption of these devices, you can get a rough idea of your home's total energy usage, which will help you select an appropriate backup battery system.

2. Determine Your Critical Loads

Critical loads refer to the total power needed by the essential devices during a power outage. Not all appliances need to run during an outage, so you should prioritize the most important devices, typically including:

• Refrigerator: To prevent food spoilage.
• Lighting: To ensure adequate lighting at home.
• Air Conditioning or Heating: To maintain comfort inside the home.

Once you have identified these critical devices, you can estimate the power demand that needs to be supported by your backup battery.

3. Consider the Duration of the Power Outage

After identifying your critical loads, the next step is to consider how long the power outage might last. The length of power outages can vary by region, and if you live in an area prone to long outages, you may need to select a larger backup battery system. A great choice for this is the iFORWAY Home Battery System, which ensures continuous power for your home during extended outages.

iFORWAY G24PRO + 5*BT30 Home Backup Battery:

• Capacity: 17,400Wh
• Output Power: 6,000W
• Connects via Bluetooth and WiFi with the iFORWAY app for real-time monitoring
• Multiple charging options (including solar charging)
• Suitable for long-term power outages, capable of powering most of your household needs

4. Calculate Your Total Load

Calculating the total load is a key step in choosing the right backup battery system. For example, if your total critical load is 3000 watts and you expect a power outage lasting 12 hours, the total energy required would be:

3000W × 12 hours = 36kWh

Based on this, you would need to choose a backup battery system with a rated capacity of at least 36kWh to ensure it won’t overload.

5. Choose the Right Backup Battery System

When selecting a backup battery, there are several factors to consider, aside from capacity and output power:

Battery Capacity and Power Output

Battery capacity refers to how much energy it can store, while power output determines how many devices can be supported simultaneously. When selecting a system, make sure the battery's capacity meets your household's energy needs, and that its power output is sufficient to run multiple devices at once.

Battery Type

Common battery types include:

• Lithium-ion Batteries: High efficiency, long lifespan, ideal for long-term use.
• Lithium Iron Phosphate (LiFePO4) Batteries: These are safer, more heat-resistant, and have a longer lifespan compared to other batteries, making them the ideal choice for high-efficiency, high-output backup battery systems.
• Lead-Acid Batteries: Low cost but less efficient, requiring regular maintenance.

For home backup systems, LiFePO4 batteries are generally the best choice due to their longer lifespan and higher efficiency.

Charging Options

An ideal backup battery system should offer multiple charging options, such as solar, AC power, and even generator charging, to ensure the battery remains charged during an outage. iFORWAY battery systems provide solar charging options, allowing you to make the most of natural resources without incurring additional costs.

Safety

Since backup batteries store significant amounts of energy, safety is paramount. Ensure the battery system you choose comes with overheat protection, overcharge protection, and short-circuit protection. iFORWAY battery systems feature advanced safety technologies and have passed stringent safety certifications.

6. Battery Life and Maintenance

The lifespan of a battery depends on several factors, with the most important being the number of charge cycles and temperature conditions. LiFePO4 batteries typically last over 3000 charge cycles, which can provide more than 10 years of service. In comparison, lead-acid batteries have a shorter lifespan, typically only 500 to 700 charge cycles. If you want a long-lasting backup battery system, LiFePO4 batteries should be your priority.

Final Thoughts

When selecting a home backup battery system, it's important to consider your household's power needs, appliance consumption, outage duration, and charging options. Systems like the iFORWAY G24PRO + BT30 and iFORWAY G36PRO + BT30 offer high capacity and efficient power output, making them ideal for many households. If you need long-term power support during outages or want to ensure reliable emergency power, these advanced battery systems are perfect choices. Additionally, using solar charging not only helps the environment but also allows you to achieve energy independence without relying on the grid.

Investing in a reliable backup battery system not only enhances your home's energy security but also provides more convenience and peace of mind for your household.
