Battery Storage – Tesla Powerwall

Solar and Wind Applications are Certified Installers of Tesla Powerwall. We can install alongside new installations or retrofit all over Scotland.

This is one of the many Lithium based battery products on the market, and certainly one of the most attractive for several reasons.

The use of a grid connected battery system like this can significantly increase your consumption of your own, clean energy and in turn reduce the requirement to import from the grid.

It is unique in that it can integrate with time of use based energy tariffs, as well as integrate with “smart” tariffs from various suppliers.

Why Tesla Powerwall?

In our opinion, Tesla Powerwall is suitable in many instances due to a combination of:

Its usable capacity – 13.5kWh

Its continuous power for both charge and discharge – configurable to suit grid permission 3.68kW-11.04kW, 5kW charge power

Possibility to install outdoors

Its warranty – 10 years, 80% retention, unlimited throughput, covers the full Tesla system

Backup functionality (with grid permission)

Option to AC or DC couple solar (or both) – Powerwall 3 introduces an integrated solar inverter with 3 MPPTs

Its good looks, if you care for that sort of thing!

Its value for money – despite its premium appearance and specification, its cost per kWh (capacity) or per kW (power capability) installed is among the best value available!

The size and type of generator being used to charge and the nature of your electricity use are fundamental to making sure the technology is suitable, and in choosing a system with appropriate characteristics. The specification of Tesla prove favourable in many cases because of capacity and power. It’s also possible to use up to 16 Powerwall 3 battery modules to increase capacity if required.
