An Introduction to Home Battery Storage

Before we get into the specifics of Franklin and Powerwall batteries, let’s do a quick overview of home battery systems.

What are home batteries and how do they work?

Home batteries, also called residential energy storage systems, store electricity for use at a later time – typically solar energy during the day for use at night.

The basic components are:

  • Battery bank – Stores the energy
  • Inverter – Converts DC electricity from solar panels into AC power for your home
  • Monitoring system – Enables remote control and monitoring

During the day, the system captures extra solar energy produced and stores it in the battery bank. At night or during an outage when solar isn’t available, the inverter taps into the stored energy in batteries to power your home.

This allows you to use more of the solar energy you produce rather than exporting excess back to the grid.

What are the benefits of adding home battery storage?

Some of the key advantages include:

  • Energy resilience – Keeps essential appliances powered during grid outages
  • Maximize self-consumption – Use your own stored solar energy vs exporting to the grid
  • Cost savings – Reduce energy bills with smart Time-of-Use management
  • Clean backup power – Eco-friendly alternative to gas generators

Now let’s see how two of the top contending home battery options – the Franklin system and Tesla Powerwall – compare across the key decision factors.

First, let’s look at some background on the two companies behind these home battery systems. Understanding their histories and areas of focus can give helpful context.

Franklin Energy Storage

  • Founded in 2019, Franklin Energy Storage is a relatively new player in the home battery space.
  • The Australia-based company focuses specifically on developing residential storage solutions.
  • Their first product, the Franklin Home Power system, was released in 2021 to target the solar self-consumption market.

Tesla Energy

  • Tesla’s energy division started in 2015 after it acquired SolarCity.
  • Tesla is a major player in home energy storage with over 1 million Powerwall units deployed.
  • In addition to the Powerwall system for homes, Tesla also sells utility-scale battery systems.

So in summary – Franklin is a newcomer that focuses specifically on home energy storage, while Tesla brings their advanced lithium-ion battery expertise from electric vehicles into the Powerwall for homes.

Next, let’s see how their first products compare.

Franklin vs Powerwall: Product Specs Compared

The table below shows a head-to-head comparison of core specs for Franklin and Powerwall home battery systems:

SpecsFranklin Home PowerPowerwall 2
Capacity13.6 kWh13.5 kWh
Max Power (Peak)10 kW7 kW
Continuous Power5 kW5 kW
Round Trip Efficiency90%89.5%
Depth of Discharge100% DoD100% DoD
Battery ChemistryLithium Iron Phosphate (LFP)Lithium-ion NCA
Warranty12 years10 years
Installer Required?NoYes

You can see the core specs are very comparable – both offer similar ~13.5 kWh capacity and 5 kW continuous power output. Peak power is the one key difference, with Franklin rated higher at 10 kW max compared to 7 kW for Tesla.

The roundtrip efficiency is also marginally better for Franklin at 90% vs 89.5% for the Tesla system.

Now let’s break down some of these key specs and terminology in more detail:

Storage Capacity

The energy capacity indicates the total amount of energy the battery can store, measured in kilowatt-hours (kWh). Both options provide approximately 13.5 kWh capacity.

For context, the average US home uses about 30 kWh per day.

So a 13 kWh battery could provide almost half a day’s power backup if needed.

Power Output

The power output determines the rate at which stored energy can be delivered from the battery, measured in kilowatts (kW).

There are two main metrics for power:

  • Peak Power – The maximum instantaneous power that can be delivered for short bursts, typically for 10 seconds. Important for running high-draw appliances like air conditioners and stoves.
  • Continuous Power – The power rating the system can sustain continuously without overheating. What you can count on for ongoing usage like fridges, lights, computers, etc.

On peak power output, the Franklin system is rated notably higher at 10 kW vs just 7 kW for the Powerwall 2.

This suggests Franklin can handle larger temporary power draws than the Tesla option. The continuous power output is identical at 5 kW for both systems.

Battery Chemistry

Both systems use lithium-ion battery technology, but the specific chemistries differ:

  • Franklin – Lithium Iron Phosphate (LFP) chemistry
  • Powerwall – Nickel Cobalt Aluminum Oxide (NCA) chemistry

The key advantage of LFP chemistry is improved thermal and chemical stability, which contributes to better safety and longevity. Tesla’s NCA chemistry offers higher energy density by volume in exchange for reduced stability.

Warranty Comparison

When making a major home upgrade purchase, warranty protection provides important peace of mind.

  • The Franklin system comes with an industry-leading 12-year warranty.
  • The Tesla Powerwall warranty is 10 years, on par with other premium batteries but with 2 fewer years of coverage compared to Franklin.

The longer 12-year warranty suggests Franklin is extremely confident in the long-term reliability of their LFP home battery system.

Ease of Installation

One potential advantage of the Franklin system is it’s designed for simplified DIY installation, whereas the Powerwall requires professional installation by a certified electrician.

Franklin utilizes an easy bolt-on mounting frame and modular battery connections for streamlined homeowner self-setup. This can avoid the added cost of hiring an installer while still meeting electrical code requirements.

Beyond just power and capacity specs, there are also key differences between Franklin and Powerwall home batteries when it comes to features, capabilities, and performance factors:


Both battery systems are modular and technically scalable, but Franklin seems better optimized for flexibility:

  • The Franklin battery uses independent 1.3 kWh LFP modules that can be added as needed. Additional batteries simply stack and bolt onto the main mounting frame.
  • Expanding Powerwall capacity requires installing whole new units with inverters. More labor-intensive and expensive to scale gradually.

So Franklin offers simpler, cheaper incremental growth capability as your needs change over time.

App Monitoring & Control

Franklin and Tesla both offer intuitive smartphone apps to monitor system performance and control settings:

  • Franklin – Can view live power flow, change operation modes, track self-consumption etc. Very user-friendly.
  • Powerwall – Provides energy data tracking and notifications. Integrates with the main Tesla mobile app.

The Franklin app functionality seems more robust overall for battery controls and solar analytics.

Backup Power & Outage Resilience

Keep in mind the Franklin and Powerwall batteries require the additional Powerwall Gateway (for Tesla) or Hybrid Inverter (Franklin) to enable full backup capability during grid failures.

Both battery systems can provide essential backup power to home loads automatically when the grid goes down. Key advantages of the Franklin system include:

  • 10 kW peak power output for high temporary draws
  • 90% roundtrip efficiency
  • Long 12-year warranty coverage

So Franklin appears well-positioned as a resilient emergency power supply for home needs.

Existing Solar System Compatibility

Franklin and Tesla batteries can both be added to retrofit existing solar PV systems, but Franklin seems better optimized for simple DIY integration:

  • Franklin easily stacks under solar arrays and utilizes plug-and-play AC coupling.
  • Powerwall retrofits often require more electrical modifications and professional installation.

So Franklin offers a more seamless upgrade path for adding batteries to an existing home solar setup.

Smart Home Integration

This is an area where Tesla dominates given their massive smart home ecosystem and advanced Powerwall integration:

  • Tesla Powerwall links directly into smart functionality across their cars, solar panels, apps, etc.
  • Franklin has no native smart home partnerships or integrations at this point.

So for those invested in a Tesla-specific smart home environment, the Powerwall is the obvious choice to complement the intelligent connectivity.
