Solarpro recommends the Tesla Powerwall to any customer hoping to become energy independent if it is coupled with a good size solar power system of 6.6kW or more.
Tesla Powerwalls have been installed and operating successfully in Australia since mid-2015. It is an AC coupled battery so it can simply be added to any existing solar power system. It has great features, such as back-up during blackout and you can set the discharge rate and minimum % of discharge.
With the ability to program the batteries priorities you can choose if the Tesla Powerwall should first dispatch electricity into your home, keep the battery in current state of charge or export power to the grid or a VPP.
Improvements and upgrades are made remotely to the Powerwall. For example, where the manufacturer has increases the power rating. The continuous power rating of a battery tells you how much power can be delivered at a constant rate. This means it will also indicate how many appliances the battery can power at the same time.
When the sun shines, Powerwall batteries can provide 8 kW continuous power and 6 kW in the evening and night. A single Powerwall can now power lights, power outlets and 240volt appliances like your fridge, TV, washing machine, and washer all at the same time, so if there is a power outage, you can still enjoy a significant amount of comfort at your home. Talk to Solarpro’s battery specialists to see if Powerwall is the best battery for you.
The Tesla Powerwall is a very popular AC coupled solar storage battery partly because it can very easily be added to an existing solar power system. It also has advanced features including automatic software updates that ensure its ‘brain’ always has the latest technology even if the battery was installed years ago. With sleek good looks as well, it’s a top choice particularly for people who already have a solar power system and are considering a solar battery purchase.
The Powerwall’s ability to produce more power off-grid is an excellent feature. It can release between 7 kW and 9.6 kW, depending on the weather conditions. The Powerwall therefore can power some additional appliances in your home if it is disconnected from the grid during a power outage.
Solarpro is delighted to be the company that installed the very first Powerwall 2 in NSW. There have been many installations since, including the one shown here of nine Powerwalls in Vaucluse.
The Powerwall’s warranty is quite typical for lithium-ion batteries, being 10 years. Furthermore, batteries do loose storage capability over the years and after 10 years it is expected that the Tesla Powerwall retains 70% of the initial capacity.
The true life expectancy has many variables such as the depth of discharge, meaning how far do you discharge the battery every time, installation conditions including exposure to hot temperatures and overall operating mode.
On the Tesla app, you are not only checking your solar generation, home consumption and energy export, including the battery’s state of charge at a glance, it also allows you to load shift energy according to your tariff. This enhances your energy savings. You can also take it to the next level by setting it to “Cost Saving” mode and let the computer decide what’s best depending on the weather and your average usage for that day. This battery really lets you step into the future!
Solarpro installed the first Powerwall 2 on the Northern Beaches in 2017, and since then added many more batteries to homes throughout Northern Sydney and the Eastern Suburbs.
Connected to a correctly sized solar power system, it is estimated it can power a family home overnight. It will enable you to have lights and appliances on in the evening, and maximising your household consumption of solar energy to save money on your electricity bill.
It is an AC coupled battery which makes it compatible with all existing solar systems, as long as the system’s capacity is big enough to have sufficient capacity to fill the battery. The Tesla Powerwall can simply be added to your current system without the need to purchase a separate battery inverter. If your existing solar system has a string solar inverter, you might want to consider installing technology to optimise your panels for maximum power generation.
The Tesla Powerwall is an attractive looking piece of modern technology. With its sleek modern design it can become a feature piece in the home. It can be mounted on an internal or external wall or sit on the ground. You can have up to 9 Powerwalls, if your home requires a massive amount of energy, and cost is no barrier.
The Powerwall has a liquid thermal control system that regulates its internal temperature to maximise battery performance in any climate, as batteries prefer cold to medium surrounding temperatures , over very hot temperatures. Despite this excellent cooling technology by Tesla, Solarpro recommends an inside installation where possible.
The SolarEdge Home Battery is a DC coupled 10kWh solar storage battery. While SolarEdge is best known for their optimised inverters, they have a lot of experience with solar batteries. They were the original battery management system for Tesla. They have close to 100,000 residential systems with batteries from Tesla and LG on them worldwide and they own Kokam, an industry leader in battery chemistry and utility storage.VIEW RANGE
There are a range of batteries which can be added to existing solar power systems and for new solar installations there are hybrids with a built-in solar inverter. Single batteries come in a choice of 5kWh, 10kWh & 13.3kWh with the option to add multiple batteries to reach 80kWh on their single phase and 51kWh on three phase.VIEW RANGE
The AC coupled 10kWh sonnenBatterieEVO can be installed outdoors. Like Powerwall it can be easily added to an existing solar power system. The DC coupled sonnenBattterie Hybrid 9.53 is impressively energy efficient at 98% and expandable from 2.5kWh to 15kWh.VIEW RANGE
