Tesla offers Off-Grid Power

The amazing Power Wall Battery of Tesla was announced last May 2015, the answered to unplug or off-the-grid living or your home totally independence in power source company. Today it is possible to run a home on solar and wind, weather can quickly wreak havoc on your plans and can swiftly bring down even the best off-grid power setup.

Elon Musk’s company Tesla is introducing a new energy storage solution that could revolutionize the renewable energy industry. The Powerwall, or Tesla Home Battery, is a wall-mounted energy storage unit — a rechargeable lithium-ion battery pack– that can hold 10 kilowatt hours of electric energy, and deliver it at an average of 2 kilowatts, all for US$3,500. Powerwall, which works like most other renewable energy storage systems.

Not cheap at all, but eventually it will free us to electric bills hike.

The Powerwall, by Tesla, is designed to hold a lithium-ion battery pack, liquid thermal control system, and software that receives dispatch commands from a solar inverter. It can be easily mounted on the wall and can even be integrated with the local grid for those who are just looking for an emergency backup power solution.

Powerwall: How it works

The Powerwall comes in a 10 kWh weekly cycle — for backup applications — and 7 kWh for daily cycles. If a home/business has a greater energy need, multiple batteries can be stored — up to 90 kWh total for the 10 kWh battery and 63 kWh total for the 7 kWh battery. The Powerwall generates 2.0 kW continuous and 3.3 kW during peak usage. It weighs 220 pounds and can be installed indoors or outdoors. The battery technology is lithium ion.

Tesla claims their battery can provide a number of different benefits to the customer including:

Load shifting – The battery can provide financial savings to its owner by charging during low rate periods when demand for electricity is lower and discharging during more expensive rate periods when electricity demand is higher

Increasing self-consumption of solar power generation – The battery can store surplus solar energy not used at the time it is generated and use that energy later when the sun is not shining

Back-up power – Assures power in the event of an outage
