Over the last 15 years, power outages across the U.S. have been getting worse.1 An out-of-date grid infrastructure can’t keep up with our increasingly plugged-in society.2 While generators offer a temporary solution in the face of a blackout, they’re dirty, noisy, and at worst dangerous.3 The good news? We’re here to make energy independence safe, simple and hassle-free.

Frequently Asked Questions

Brightbox stores energy to provide reliable backup when the sun isn’t shining or in the event of an outage. However, one Brightbox battery system can’t store enough solar power to supply your home’s entire electricity consumption for approximately 8 to 12 hours, which is why you have to stay connected to the electric grid.

Just like solar panels, the size of your Brightbox solar battery storage service is determined by your unique energy needs and habits. Factors such as the amount of electricity you use at home and the devices and appliances you want to back up will play a key role when selecting the right battery storage solution for you.

While some battery units allow you to store electricity directly from the grid, with Brightbox solar battery storage service, the energy is harnessed entirely from the sun. Meaning it’s 100% clean, renewable and free of charge, so you don’t have to pay your utility for the extra power to charge your battery.

The installation of Brightbox is a relatively simple process. It’s about the size of a water heater, and the system is mounted on a wall, usually inside your garage or outside of your home.

While Brightbox requires an Internet or cellular connection to monitor your energy storage and usage efficiently, it can still operate without it. If for some reason Brightbox happens to go offline, you can resume your usage tracking when your internet connection is back to normal.

Most residential batteries are installed and configured with baseline settings by your solar installer. Batteries last anywhere between 10 and 15 years, and manufacturers typically offer a 10-year warranty. Still, Brightbox is more than battery storage; it’s a holistic service that includes professional maintenance and monitoring for 25 years with select plans: two actions which may prolong your battery unit’s life.

Brightbox allows you to store the electricity your solar energy system produces during the day and use it when you need it most—for instance, in the evening, at night, or when the electric grid fails due to an extreme weather event or physical damage to the equipment.

Brightbox is a holistic solar battery storage service that offers you clean, safe, reliable backup power to have better control over your home energy use and cost.

Brightbox solar battery storage system saves you money on utility bills, protects your home from power outages, and reduces your carbon footprint by supporting the production of clean, renewable energy.
