The Best in the Industry Put Their Trust in Us

Our proven track record of superior engineering, high-quality installations and
excellent customer service has earned us the highest certifications in the industry.

Why should I choose a Franklin whole-home battery for my Arizona property?

Arizona homes require robust energy management to handle high air conditioning loads and intense heat. A Franklin battery provides seamless backup power, efficiently manages heavy loads, and features advanced cooling technology to operate safely in temperatures up to 131° F.

Unmatched Energy Efficiency for High Temperatures

The Franklin whole-home battery is specifically engineered to perform reliably in extreme climates like Arizona. Its advanced cooling systems regulate internal temperatures, ensuring optimal performance even during the hottest summer days, reducing strain on the battery and enhancing its lifespan.

Seamless Integration with High-Load Devices

With the ability to handle high power demands, the Franklin battery seamlessly supports energy-intensive appliances such as air conditioners. This smooth integration ensures your home remains comfortable and functional, even during peak energy usage times or power outages.

Can the Franklin aPower 2 and aPower S power my entire house during an outage?

Yes. The Franklin aPower 2 delivers 10 kW of continuous power and handles high surge currents, while the aPower S delivers 5 kW. Both can run essential household appliances during grid outages, with the aPower 2 being better suited for homes with high-capacity air conditioning units or other demanding loads.

How long can the Franklin aPower 2 and aPower S backup last?

The duration of backup power from the Franklin aPower 2 and aPower S systems is not a fixed number but is influenced by two primary factors: the total capacity of your installed battery system and your household’s real-time energy consumption during an outage.

With strategic energy management, which involvesprioritizing essential appliances like refrigerators, lighting, and medical devices while minimizing the use of high-draw appliances, both the aPower 2 and aPower S can deliver reliable backup power. This can range from several hours to a full day or more, ensuring your home remains functional and secure. For homeowners seeking prolonged energy independence during extended grid failures, the system’s modular design is a key advantage.

Are the aPower 2 and aPower S compatible with solar?

Yes, both the Franklin aPower 2 and aPower S batteries are engineered for seamless integration with solar energy systems. This compatibility allows homeowners to store excess solar power generated during daylight hours, creating a personal energy reserve. By capturing and storing this energy, you ensure a continuous and reliable power supply throughout the night or during grid outages. This process not only enhances your energy independence but also maximizes the efficiency and return on your renewable energy investment, reducing reliance on the grid and promoting a more sustainable lifestyle.

What is the difference between the aPower 2 and the aPower S?

While both are premium energy storage solutions, the Franklin aPower S features a fully integrated design that allows for direct solar connection without an external inverter. The aPower 2 is designed to work seamlessly with any existing solar inverter setup while providing massive continuous output for demanding home loads.

How does the aPower S support direct solar integration?

The aPower S eliminates the need for an external inverter by incorporating advanced technology that enables a direct connection to solar panels. This streamlined design simplifies installation, reduces hardware costs, and improves system reliability, making it an ideal choice for homeowners.

What do you gain with the aPower 2?

The aPower 2 stands out for its high continuous power output, capable of handling heavy home energy loads with ease. Its compatibility with a wide range of existing solar inverters offers homeowners greater flexibility in integrating it into their renewable energy systems, ensuring maximum performance across various setups.

How long do Franklin batteries last?

Yes. The Franklin aPower 2 delivers 10 kW of continuous power and handles high surge currents, while the aPower S delivers 5 kW. Both can run essential household appliances during grid outages, with the aPower 2 being better suited for homes with high-capacity air conditioning units or other demanding loads.

How efficient are Franklin batteries?

Franklin batteries are designed with advanced energy storage technology to maximize efficiency. With a round-trip efficiency of over 90%, these batteries minimize energy loss, ensuring that homeowners can store and use their renewable energy effectively. This high level of efficiency supports greater energy savings and contributes to a more sustainable energy footprint.

Are Franklin batteries safe?

Safety is a top priority for Franklin batteries. Utilizing Lithium Iron Phosphate (LFP) technology, they offer superior thermal and chemical stability compared to other battery chemistries. Additionally, Franklin batteries are equipped with built-in safety features, such as advanced temperature and voltage monitoring systems, to ensure optimal performance and prevent risks associated with overheating or overcharging.
