Head-to-Head Comparison: Franklin Home Power vs Tesla Powerwall
When comparing home energy storage solutions, the Franklin Home Power and Tesla Powerwall are often top of mind. Both offer similar energy storage capacities, with Franklin Home Power providing 13.6 kWh per unit and the Tesla Powerwall a slightly lower 13.5 kWh. However, there are several features that set them apart, including peak power output and warranty terms, which are critical factors for homeowners choosing a solar battery.
We’ll delve deeper into their differences and similarities, examining:
- their energy storage capabilities
- efficiency
- performance
- warranty
These are key elements in assessing home energy storage solutions, which are designed to store energy efficiently.
Energy Storage Capabilities
One of the key features of any solar battery is its energy storage capacity, also known as battery capacity. An individual Franklin Home Power battery unit has a storage capacity of 13.6 kWh, which can be fully utilized without harming the battery. This is a significant advantage over other batteries on the market that don’t allow for full usage of their capacity.
But what truly sets the Franklin Home Power system apart is its scalability. The design of the system allows for up to 15 units to be combined, achieving a maximum combined energy storage capacity of 204 kWh. This scalability means that you can start with fewer units and expand as your energy needs grow.
Efficiency and Performance
Another pivotal factor of solar batteries is their efficiency. It’s about how much electricity can be utilized after the battery has been charged. For example, Franklin Home Power batteries boast a round-trip efficiency of 89%, meaning that there’s an 11% loss of energy during storage.
On the other hand, the Tesla Powerwall has a slightly higher round-trip efficiency of 90%. While this difference might seem small, every percentage point counts when it comes to maximizing the utility of stored solar power.
Warranty and Longevity
In terms of warranty and longevity, Franklin Home Power surpasses the typical 10-year standard for solar batteries with a 12-year warranty. It’s worth noting here that both Franklin Home Power and Tesla Powerwall guarantee a minimum of 70% capacity retention at the end of their respective warranty periods. This assurance gives homeowners peace of mind knowing that their investment will continue to deliver value for many years.
Breaking Down the Technical Specifications
Delving into technical specifications provides a more detailed comparison between Franklin Home Power and Tesla Powerwall. Both systems offer a continuous power output of 5 kW, which is the power level that a battery can supply consistently over time. This output is vital for the operation of essential home appliances.
Yet, Franklin Home Power excels in providing backup power during a grid outage with a peak power output of 10 kW, compared to Tesla Powerwall’s 5 kW. Peak power is crucial for starting up large appliances that require a surge of power, especially when relying on DC electricity.
Continuous Power vs Peak Power
Understanding the difference between continuous power and peak power is fundamental in comprehending home energy storage. Continuous power output indicates the level of power that a battery can supply consistently over time, which is vital for powering essential home appliances. Both the Franklin Home Power battery and the Tesla Powerwall offer a continuous power output of 5 kW.
Peak power, on the other hand, determines the battery’s ability to handle short-term high energy demands. This is particularly important during power outages when turning on appliances like air conditioners and dryers. Here, Franklin Home Power has the upper hand with a peak power output of 10 kW compared to Tesla Powerwall’s 5 kW. So, how much power can be provided during these peak times is crucial for homeowners.
Depth of Discharge and Battery Health
The depth of discharge, indicating the percentage of the battery’s capacity that can be used without inflicting damage, is another vital aspect to consider. For solar batteries, a higher depth of discharge is generally more desirable. However, using the entire capacity of a battery can shorten its life and reduce its ability to hold a charge over time.
In this respect, Franklin Home Power battery shines with a depth of discharge rating of 100%, indicating optimized energy use without harming the battery. This is a significant advantage, as the lifespan and performance of home battery systems, including their capacity to hold a charge, decline over time with their depth of discharge.
Design and Installation Considerations
Other significant aspects to consider when comparing the Franklin Home Power and Tesla Powerwall are design and installation. Franklin Home Power systems utilize a two-component structure known as aPower for the battery and inverter, and aGate for grid, solar, and energy management connections. The AC-coupling design of the Franklin Home Power batteries allows for compatibility with both new and existing solar installations, providing flexibility in home energy storage solutions.
The Franklin Home Power’s modular design, which can be expanded via additional aPower units, caters to the needs of different household sizes and energy requirements. Furthermore, ease of installation is a key advantage of Franklin Home Power, which can be integrated into home energy systems without extensive or complicated electrical work.
Modular Battery Systems
The modular design of both systems allows for flexibility in meeting varying energy demands. The Tesla Powerwall system allows for the addition of multiple Powerwall batteries, paired with a Backup Gateway or Backup Switch, for homeowners to flexibly augment their energy storage according to need.
On the other hand, the Franklin Home Power system can integrate up to 15 aPower batteries using an aGate controller, enabling scalability for higher energy demands. This level of scalability is a boon for homeowners who anticipate their energy needs to grow over time.
User Experience and Control
