The right home battery depends on what you need it to do. Some homeowners want whole-home backup during grid outages. Others prioritize maximizing solar self-consumption or taking advantage of time-of-use rate arbitrage. Before comparing specific products, it helps to understand the key specifications that matter most.
Usable capacity (measured in kWh) determines how much energy the battery can store. Continuous power output (measured in kW) determines how many appliances it can run simultaneously. Round-trip efficiency tells you how much energy is lost in the charge/discharge cycle. And the warranty — typically measured in years and throughput cycles — indicates how long the manufacturer stands behind the product.
For New Jersey homes, backup power capability during nor'easters and summer storms is a major consideration. Systems that can start and run without the grid (called "islanding") are essential if outage protection is a priority.
Claim: Continuous power output is as important as capacity when sizing a battery for whole-home backup.
Evidence: A battery with 13.5 kWh of capacity but only 5 kW of continuous output cannot run a central air conditioner (which typically draws 3–5 kW) alongside other household loads. Homeowners who want to back up HVAC, well pumps, or electric ranges need systems rated for 7.6 kW or more of continuous power.
The Tesla Powerwall 3 is one of the most recognized home batteries on the market. It offers 13.5 kWh of usable capacity and a built-in hybrid inverter, which means it handles both solar DC-to-AC conversion and battery charging in a single unit. This simplifies installations and can reduce total system cost by eliminating the need for a separate solar inverter.
Powerwall 3 delivers up to 11.5 kW of continuous power output, which is enough to run most whole-home loads including air conditioning. It supports full off-grid islanding and integrates with the Tesla app for monitoring and control. Multiple units can be stacked for larger homes.
The main consideration with Powerwall is availability and installer access. Tesla has historically managed its own installation network, though third-party certified installers (including Powerlutions) now have expanded access in New Jersey.
Claim: Powerwall 3's integrated inverter can reduce total system installation costs compared to AC-coupled battery setups.
Evidence: By combining the solar inverter and battery inverter into one unit, Powerwall 3 eliminates one major hardware component and reduces wiring complexity. For a typical residential install, this can save $1,000–$2,000 in equipment and labor compared to pairing a standalone string inverter with a separate AC-coupled battery.
FranklinWH takes a different approach by positioning itself as a whole-home energy management system rather than just a battery. The system centers on the FHP (FranklinWH Home Power) gateway, which manages power flow between solar, battery, grid, and generator inputs. Battery modules (called aPower units) each provide 13.6 kWh and can be stacked up to three or more per gateway for over 40 kWh of total capacity.
Each aPower battery delivers 5 kW of continuous power, and multiple units combine their output. A two-battery FranklinWH system provides 10 kW continuous — sufficient for most whole-home backup scenarios. The system supports 200A whole-home backup without a sub-panel, which is a significant advantage for homeowners who want seamless coverage without rewiring their electrical panel.
FranklinWH also integrates with third-party solar inverters, making it a flexible choice for retrofits or installations where the homeowner wants to keep their existing inverter brand.
Claim: FranklinWH's whole-home backup capability without a sub-panel simplifies installation for existing homes.
Evidence: Most competing battery systems require a critical loads sub-panel to isolate backed-up circuits during an outage. This adds $500–$1,500 in electrical work and limits which circuits get backup power. FranklinWH's gateway manages the full 200A panel, so every circuit in the home is covered without additional panel work.
Enphase brings its microinverter philosophy to energy storage with the IQ Battery 5P. Each unit provides 5 kWh of usable capacity and 3.84 kW of continuous power. The modular design means you can install one, two, three, or more units depending on your needs, scaling capacity in 5 kWh increments.
The Enphase system pairs naturally with Enphase IQ microinverters, creating an all-Enphase ecosystem that simplifies monitoring through the Enphase app. Each battery module contains its own microinverters, so there is no single point of failure — if one module has an issue, the others continue operating.
The tradeoff is that reaching large capacities (15+ kWh) requires multiple units, which can take up more wall space than a single large battery. For homeowners who want modest backup (lights, refrigerator, internet) rather than whole-home coverage, one or two IQ Battery 5P units may be the most cost-effective option.
Claim: Enphase's modular battery architecture reduces risk through redundancy.
Evidence: Each IQ Battery 5P module operates independently with its own microinverters. If one unit requires service, the remaining units continue to provide backup power and solar storage. In contrast, a single-unit battery system loses all storage capability if the unit goes offline for maintenance or repair.
The SolarEdge Home Battery is designed to work with SolarEdge's Energy Hub inverter, creating a DC-coupled storage system. DC coupling means solar energy goes directly into the battery without being converted to AC first, which improves round-trip efficiency (typically 90%+ for the SolarEdge system).
The battery offers 9.7 kWh of usable capacity per unit and 5 kW of continuous output. Up to three units can be stacked for 29.1 kWh total. The SolarEdge system integrates with the company's power optimizers, which are attached to each solar panel to maximize individual panel output — particularly useful on roofs with partial shading.
For homeowners already using or planning to use SolarEdge inverters and optimizers, the Home Battery is a natural addition. The tight integration means fewer compatibility concerns and a single app for monitoring panels, battery, and home energy usage.
Claim: DC-coupled battery systems like SolarEdge offer higher round-trip efficiency than AC-coupled alternatives.
Evidence: In an AC-coupled system, solar energy is converted from DC to AC by the solar inverter, then back to DC for battery storage, then back to AC for use — each conversion loses 2–5% efficiency. DC coupling skips the intermediate AC stage, preserving more energy. Over a year, this can mean 5–10% more usable energy from the same solar array.
The following table compares the four leading home batteries across the specifications that matter most for New Jersey homeowners. All values reflect publicly available manufacturer data as of early 2026.

Claim: No single battery is the best choice for every homeowner — the right pick depends on your existing equipment, backup needs, and budget.
Evidence: A homeowner with SolarEdge optimizers already installed gets the most value from the SolarEdge Home Battery due to DC coupling efficiency. A homeowner who wants whole-home backup without rewiring benefits most from FranklinWH. Someone building a new system from scratch may find Tesla Powerwall 3's integrated inverter the most cost-effective approach. Each product excels in a different scenario.
Installing a home battery in New Jersey involves more than just choosing a product. Permitting requirements vary by municipality, and your installer must coordinate with your local utility for interconnection approval. The process typically takes 4–8 weeks from signed contract to operational system, though timelines can vary.
Physical installation requirements also differ by product. Tesla Powerwall and FranklinWH units are wall-mounted and weather-rated for outdoor installation. Enphase IQ Battery modules are also outdoor-rated but require more wall space when stacking multiple units. SolarEdge Home Battery is typically installed indoors or in a garage.
Electrical panel upgrades may be needed depending on your existing panel's age and capacity. Homes with older 100A panels may need an upgrade to 200A service to support both solar and battery systems. Your installer will assess this during the site survey.
Claim: Choosing an installer experienced with your specific battery brand reduces installation delays and commissioning issues.
Evidence: Each battery system has unique wiring requirements, communication protocols, and commissioning procedures. Installers certified by the manufacturer complete installations faster and are less likely to encounter configuration errors that delay utility interconnection approval. This is especially important for FranklinWH and SolarEdge systems, which require specific gateway or inverter pairings.
The right battery size depends on three factors: how much backup you want during outages, how much solar energy you want to store for evening use, and your budget. Here is a practical sizing guide.
Claim: Most New Jersey homeowners need 10–20 kWh of battery capacity for meaningful backup protection.
Evidence: The average NJ home consumes about 28 kWh per day. Essential loads (refrigerator, lighting, internet, phone charging) typically account for 8–12 kWh per day. A single 13.5 kWh battery covers essential loads for about 24 hours. For whole-home backup including HVAC, two batteries (27+ kWh) provide roughly one day of full coverage without solar recharging.
Enphase offers the longest standard warranty at 15 years. FranklinWH provides 12 years. Tesla Powerwall and SolarEdge both offer 10-year warranties. Longer warranties generally indicate higher manufacturer confidence in long-term battery cell durability.
Yes. AC-coupled batteries like FranklinWH and Enphase work with any existing solar inverter. If you have a SolarEdge inverter, the SolarEdge Home Battery adds DC-coupled storage with minimal changes. Tesla Powerwall 3 can also retrofit onto existing systems, though the integrated inverter is most cost-effective on new installations.
It depends on the battery capacity and your power consumption. A single 13.5 kWh battery can run essential loads (lights, refrigerator, internet) for roughly 24 hours. For whole-home backup including HVAC, expect 8–12 hours from a single unit. With solar panels recharging the battery during daylight, backup can extend indefinitely for essential loads on sunny days.
Both can provide whole-home backup. FranklinWH's key advantage is 200A whole-home backup without a sub-panel, which avoids additional electrical work. Tesla Powerwall 3 offers higher continuous power output per unit (11.5 kW vs. 5 kW). The best choice depends on your electrical panel setup, budget, and whether you need the higher power output for large loads like central AC.
Claim: The best home battery choice depends on your existing solar equipment, electrical panel, and backup priorities.
Evidence: Homeowners with SolarEdge inverters benefit from DC coupling with the SolarEdge Home Battery. Those with older panels and no desire to rewire benefit from FranklinWH's 200A gateway. Budget-conscious homeowners who want modular scalability benefit from Enphase. A qualified installer evaluates these factors during a site survey to recommend the right system.
The home battery market in 2026 offers more capable and more affordable options than ever before. Whether you prioritize whole-home backup, modular flexibility, or tight integration with your existing solar equipment, there is a product that fits.
