Battery Storage FAQs

What is battery storage?

Battery storage systems for homes and businesses are essential to support the growing renewable energy generation market and see the replacement of fossil fuels. Lithium-ion batteries like those in our mobile phones or electric cars are the dominant solution to store energy for when we need it, rather than trying to use it when it's being generated. The Sun isn't always shining and wind isn't always blowing, so to manage our own homes or businesses electricity supply, we can now install highly efficient, smart battery systems. We can then either use a PV system to generate what we need, storing the excess for later, or purchase electricity at its cheapest and store it. Energy Storage Systems are designed to be supplied from AC or DC electricity for AC coupled storage, or DC coupled storage.

What is a Tesla Powerwall 2?

Tesla's PowerWall 2 is a battery that stores energy, detects outages and could automatically become your home's energy source when the grid goes down. The Powerwall's energy capacity is 13.5 kWh, more than enough energy to take the average home off the grid for over 24 hours, with 100% depth of discharge and a 90% round trip efficiency. Unlike generators, Powerwall keeps your lights on and phones charged without upkeep, fuel or noise. Pair with solar and recharge with sunlight to keep your appliances running for days. Use Powerwall alone or combine it with other renewable products to reduce your carbon footprint and prepare your home for power outages. Powerwall reduces your reliance on the grid by storing your solar energy for use when the Sun isn’t shining. With easy installation and a minimalist design, Powerwall complements a variety of home styles. The compact, all-in-one construction features versatile mounting options for indoor or outdoor spaces. With the Tesla app, you can monitor your home’s energy production and consumption in real time. Set your preferences to optimise for energy independence, outage protection or savings. With instant alerts and remote access, you can control your system from anywhere.
