Solar Batteries

Weather any storm outage with a reliable battery solution from A1A Solar.

Your solar panel or wind-powered systems won’t work if the power goes out during rough weather conditions unless you have a backup battery. A solar photovoltaic (PV) system plus a lithium-ion battery backup bank plus an optional generator gives your family off-grid security when accidents, blackouts and natural disasters strike. A backup generator offers you peace of mind during a power outage and complements your solar energy system to ensure you’re never without power. Battery systems provide improved energy security, and a custom design and installation meets your needs by providing the ideal power system. Now, new and existing PV customers can continue using their solar and wind-powered systems and keep the lights on when the grid goes down. A1A Solar offers the following solar battery solutions:

Tesla Powerwall

My husband and I bought solar from A1A, with two Tesla Powerwall batteries a little over a year ago. We love our system! The process was easy. [They have] been communicative and reachable the whole time, and explained everything to us, and we had lots of questions… Our system only took two days to put in, and the guys who put the panels on the roof were very professional. We got a big tax refund from the IRS because we went solar. Couldn’t be more thrilled! — Valerie, Fernandina Beach, Florida

The Tesla Powerwall offers the highest standard of residential solar batteries on the market. Equipped with a Gateway management system and a built-in inverter, a Tesla Powerwall allows for smart monitoring and management. Powerwall reduces reliance on the grid by storing solar energy for use when the sun isn’t shining. Its system can detect grid outages and automatically activate to keep energy powering to your home. Unlike gasoline generators, Powerwall keeps your lights on and phones charged without upkeep, fuel or noise. Its standard power output of 5 kW, can power things such as lights, electrical outlets, and small 120-volt appliances. Need more power? Additional Powerwalls can be connected to meet any electrical demand. Its system size flexibility means with a quantity of Powerwalls, you can back up your entire home – air conditioner and all!

What really makes the Powerwall stand out are its three operating modes:

  • Solar Self-Consumption
  • Time-Based Control
  • Backup Power


The sonnenBatterie is a complete system – ready for connection – with an extremely durable battery, an inverter, intelligent energy  measurement technology and the software to operate it all smoothly. In contrast to most other battery systems in the market, the sonnenBatterie components are build into a single high-quality casing and perfectly attuned to each other – thereby ensuring a very high longevity and maximum quality with a small footprint.

The sonnenBatterie is based on the most reliable and sustainable battery technology available and exclusively uses lithium iron phosphate batteries (LiFePO4). These batteries offer a greater longevity and higher safety than most other lithium-ion batteries that are commonly used in smartphones, laptops or electric cars.
