A whole home battery backup system is a comprehensive solution designed to provide uninterrupted power to all circuits and appliances during a grid outage. It is designed to handle simultaneous power demands from multiple devices, including essentials like air conditioning, electric hot water heaters, dryers, and stoves. This system offers flexibility as homeowners can prioritize the circuits and appliances to power during outages.
These systems have ample energy storage capacity, ensuring sufficient power for extended outages. They can be charged using utility grid electricity or solar power, leveraging solar panels to recharge the batteries during the day.
Whole home battery backup systems offer numerous benefits. They provide energy independence by reducing reliance on the public power grid, making them especially valuable in areas prone to outages. By utilizing clean energy, these systems help lower carbon emissions and promote a cleaner environment compared to fossil fuel-based generators.
With access to all circuits in the home, users can selectively power essential appliances during grid outages. Finally, whole home battery backups operate quietly, eliminating generator noise and disturbance.
The cost of whole home battery backup systems typically ranges from $3000 to $15,000, excluding installation expenses. The actual prices can vary significantly based on power output, storage capacity, home size, average electricity consumption, and other considerations.
Factors That Affect the Cost of a Whole House Battery Backup System
Several factors influence the cost of a whole house battery backup system. These include:
Battery size plays a key role in the cost of a whole-house backup system. Larger batteries store more electricity and provide longer backup power but can be very costly. The cost per kilowatt-hour decreases as the battery size increases.
The average household uses 30 kWh per day, so a backup system of that size would maintain normal electricity consumption for one day. Following energy-saving practices during a blackout, such as minimizing refrigerator use and reducing heating/cooling, can lower battery capacity requirements.
Power Output Capacity
Battery storage capacity is the amount of energy a battery can hold and is measured in watt-hours or kilowatt-hours. Power output capacity determines how much electricity the battery can provide at once and is measured in watts or kilowatts.
To determine your power needs for appliances:
- Identify the wattage requirements of your appliances
- Convert volts/amps to watts using the formula: Volts (V) x Amps (A) = Watts (W).
- Add up the running watts of your appliances, ensuring it stays within the rated power output of your battery system.
- Account for the highest starting wattage by adding it to the running wattage total.
This final sum represents the total starting watts you need from your battery system.
Installation costs can vary based on the type of home battery backup system you purchase. Standalone portable power stations are easy to set up and generally do not require extensive installation. When you want to integrate a whole-house backup battery system with your existing home wiring, minor installation costs may be involved.
To ensure continuous power supply during extended outages, it is advisable to choose a whole home battery backup system with multiple charging options, including solar.
The U.S. Energy Information Administration states that an average household consumes approximately 886 kWh of electricity per month or 30 kWh per day. To sustain this level of consumption during a blackout, a backup battery system with a capacity of 30 kWh would be required to power the house for one day under normal consumption conditions.
Which Whole House Battery Backup System Is Right for You?
When assessing different whole-house battery backup systems, you must consider several factors apart from the cost. These include the expected lifespan of the backup battery system, the time to recharge, the maintenance needs, the battery chemistry and efficiency. The terms and conditions of the manufacturer’s warranty must also be checked closely.
The lowest-priced whole house battery may be an attractive temptation, but the consequences of buying one can be unpleasant. Always evaluate the lifespan of a battery before investing in one by checking the life cycle.
A cycle is defined as each instance of discharging and recharging the battery. The number of cycles a battery can endure without experiencing a decline in efficiency is primarily influenced by its chemistry. Consider the battery's chemistry and choose a system that ensures long-term reliability at a reasonable cost.
Battery Chemistry and Efficiency
Lead acid batteries, the cheapest option for backup battery chemistry, rely on outdated technology. These batteries are commonly found in TV remotes, flashlights, and older cars. Lead acid batteries are better, but their lifespan is limited to a few hundred cycles. Modern batteries use technologies such as lithium iron phosphate. They offer significantly longer lifespans, lasting thousands of cycles without losing efficiency.
The latest generation of lithium iron phosphate batteries can endure up to 6500 cycles, equivalent to over a decade of average use.
Lead acid battery systems require frequent maintenance. The distilled water must be added regularly. Discharging below 50 percent capacity must be prevented to avoid permanent damage. They also require well-ventilated storage conditions and may deliver below-par performance in extreme temperatures.
Lithium-iron phosphate batteries do not need regular maintenance. They can be deeply discharged without adverse effects and operate within a wider temperature range.
Backup systems of poor quality are incapable of providing extended warranties. It is a reflection of their lack of confidence in the product. Reputable companies typically offer extended warranties for their products.
