Let’s take a look at some of the most popular options in solar battery storage available in Australia…

Tesla Powerwall 2

You have no doubt heard of the Tesla Powerwall, we have completed some incredible solar systems with a huge number of panels and multiple Tesla Powerwall 2 battery storage units to power the whole house. The Powerwall 2 has 13.5kw storage from an AC coupled battery that is compatible with any existing or new solar system. It also has one of the best solar battery monitoring apps available today. Plus the Tesla Powerwall 2 can optimize its operation with time of use tariffs to help you through the expensive evening peak periods using solar battery power. As you would expect from a strong brand like Tesla, the Powerwall is supported by a 10 year warranty and is widely regarded as the best battery storage option currently available.

Powerwall is a battery that stores energy, detects outages and automatically becomes your home’s energy source when the grid goes down. 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. Powerwall reduces your reliance on the grid by storing your solar energy for use when the sun isn’t shining. Use Powerwall alone or combine it with other Tesla products to save money, reduce your carbon footprint and prepare your home for power outages.

At Dunton Group Solar & Electrical we strongly recommended the Tesla Powerwall 2 as a reliable and high performing battery storage option, having installed plenty in recent years we can confidently say they are a product we would happily install at our own homes.

The option provides the opportunity to either remove the existing inverter and replace with a hybrid option or add to a stand alone solar system. Backed by a 10 year warranty it is a high value option.

Can I add a Powerwall to my existing solar system? Adding a Powerwall 2 to an existing solar system is something Dunton Group have done on numerous occasions. Powerwall 2 (AC) can be coupled with any solar power system, so if you have existing solar and would like more information on batteries please get in touch. This is called AC-coupling, the AC Powerwall 2 communicates with the Tesla Gateway to determine when to charge and when to discharge.

The Tesla Powerwall 2 is manufactured in Tesla’s Gigafactory based in Nevada in the United States of America providing a high quality manufacturing and quality assurance process.

There is little to no maintenance required for a Tesla Powerwall, Tesla can update the firmware on your Powerwall remotely via software updates to keep your Powerwall operating at its absolute best performance.

Your Tesla Powerwall can be charged and discharged multiple times per day, this effectively matches surplus solar generation with periods when your energy usage exceeds what your solar system is producing on a regular basis. If your solar system is producing more power than your home is using and your Powerwall is fully charged, the excess solar power will be sold to the grid as per usual.

The other strength of using Tesla products is that Tesla warrants that your Powerwall will be free from defects for 10 years following the date it was first installed. In order to provide the full 10 year warranty period, Tesla requires the ability to update your Powerwall through remote firmware upgrades. Dunton Group will help connect your Powerwall to your home Wi-Fi network and register your system with Tesla. When your Powerwall is installed and connected to the internet, Tesla will update your Powerwall through over-the-air software upgrades from time to time as required. This helps to ensure your Powerwall is operating at its best.
