Everything you need for whole-home energy management
Connects solar, batteries, grid, and generator into a single intelligent system - no separate components to manage.
When the grid drops, FranklinWH switches to battery in milliseconds - so fast your lights won't even flicker.
Automatically charges batteries when rates are low and discharges when rates are high - saving you money without any effort.
Start with one 13.6 kWh battery and add up to 15 units as your needs grow. From essential backup to whole-home independence.
The FranklinWH aGate is the central hub that ties everything together. It coordinates your solar panels, battery storage, grid connection, and even a backup generator - routing power where it's needed most. The system learns your usage patterns over time to optimize energy flow automatically.
The FranklinWH app shows you exactly what's happening with your energy - how much your panels are producing, how full your batteries are, and where your power is going. Choose from preset energy plans or create your own to match your lifestyle and rate schedule.
After Winter Storm Uri, Texas homeowners know that grid reliability isn't guaranteed. FranklinWH keeps your home running through outages - your HVAC, fridge, Wi-Fi, and lights stay on while your neighbors go dark. With solar recharging your battery during the day, you can ride out extended outages for days.

FranklinWH integrates with all major solar and energy brands
Tesla Powerwall is a compact lithium-ion battery designed to store energy from your solar panels or the grid. It provides seamless backup power during outages, integrates with solar to reduce your reliance on utility companies, and lets you schedule charging around time-of-use rates - all managed through the Tesla app. With its slim wall-mounted design, Powerwall fits neatly in a garage or on an exterior wall without taking up valuable space.
If you want a reliable whole-home backup that pairs effortlessly with solar, Powerwall 3 delivers. The latest generation packs a built-in solar inverter and higher surge capacity into a smaller footprint - meaning fewer components on your wall and more power when you need it. As a certified Tesla Powerwall installer in North Texas, Solarize can evaluate your home and help you determine if Powerwall is the right fit for your energy goals.
As a certified Tesla Powerwall contractor, Solarize brings the full benefit of Tesla's battery technology directly to homeowners across the DFW metroplex. From your first consultation through final commissioning, our licensed electricians handle every step of the installation. We pair Powerwall with your existing or new solar array so your home generates, stores, and uses its own clean energy - giving you real independence from rising utility costs and an unreliable grid.
It depends on the size of the battery and how much energy you are using. A single Powerwall (13.5 kWh) or FranklinWH aPower (13.6 kWh) can typically power essential loads - lights, fridge, Wi-Fi, and phone chargers - for 10 to 12 hours. With solar panels recharging the battery during the day, you can extend backup for multiple days. Adding more battery units increases your capacity further.
Both are excellent whole-home battery systems, but they take different approaches. FranklinWH uses a central hub (the aGate) that manages solar, battery, grid, and generator inputs in one system - ideal for homes that want full energy orchestration. Tesla Powerwall 3 has a built-in solar inverter, which simplifies installation and reduces the number of components. We help you choose the best option based on your home, solar setup, and energy goals.
Yes. Both systems are designed to scale. FranklinWH supports up to 15 battery units (204 kWh total), and Tesla Powerwall allows up to 4 units per system. We size your initial installation for your current needs and pre-wire for future expansion so adding capacity later is straightforward.
No. You can install a battery system without solar panels and use it purely for backup power or to take advantage of time-of-use rate arbitrage - charging from the grid when rates are low and using stored energy when rates are high. That said, pairing a battery with solar maximizes your savings and gives you the most energy independence.
Both FranklinWH and Tesla Powerwall are warrantied for over a decade - FranklinWH offers a 12-year warranty and Tesla provides a 10-year warranty. In practice, lithium-ion batteries typically retain 70-80% of their original capacity after the warranty period, so they continue to perform well beyond the coverage window.
Absolutely. That is one of the primary reasons homeowners install battery storage. Both FranklinWH and Powerwall detect a grid outage and switch to battery power in milliseconds - fast enough that you will not notice the transition. If paired with solar, the panels continue to charge the battery during the outage so you can maintain power indefinitely during daylight hours.
