Powerwall is a state of the art battery system for residential and light commercial applications that enables the storage of solar energy. It a high quality rechargeable lithium-ion battery with smart software and user-friendly smartphone app at a relatively affordable price. It is one of the most popular options for home backup power and EV charging. It can automatically detect a power outage, disconnect from the grid, and then restore power to your home in no time that you may not be even aware of the outage.

The Tesla Powerwall is paired with a home solar panel system. Solar panels produce more electricity during daytime. This extra solar power is intelligently stored in the Powerwall instead of being sent back to the electric grid. At night or when the production is less or nil, the homeowner can pull energy from the Powerwall instead of buying from utility for a higher price

Increases self-consumption of solar power generation

Powerwall can store surplus solar energy during daylight hours and use that energy later when the sun is not shining.

Time Based

Powerwall can charge during low rate periods when demand for electricity is lower and discharge during more expensive rate periods when electricity demand is higher.

This will result in lower installation costs and a much easier installation process.

Each Powerwall offers 13.5kWh of usable energy storage capacity and can be stacked in a chain. This self-contained, waterproof unit is always on. It operates quietly, and can be mounted on the floor or wall individually or as part of a stack of multiple batteries. It requires minimal maintenance, receives OTA updates, and is about half the size an average door – 44 inches tall by 29 inches wide

The Tesla app offers seamless monitoring for the customers. Through the use of real-time data, consumers can monitor and track their system. This gives a clear understanding of their energy usage and habits which in turn helps them to reduce their electricity bills.
