Unfortunately, it’s not possible to see the financial benefit from the battery alone when the payback is combined like this. The prices listed below do not include installation costs, which you can assess by using Solar Choice’s comparison tool. Solar installations on roof tops are often blamed as the cause of this, although at night, the voltage on the lines is almost always greater than the nominal 240volt. How does adding a AC battery system to an existing Solar setup work in South Australia with the 5kW export limiting? It has been designed specifically as a home energy storage battery. It removes the retailer as ‘middle-man’ and could save you thousands of dollars. Unlike many companies we actively monitor our installers based on high standards including minimum levels of feedback and industry required registrations. The maximum subsidy per system is $6,000. Wow Tim that is a huge system. HI Tim, how can I contact you ? And Australian implications are about 22 times bigger than German implications. The usable storage capacity is 90% of this. A 15 kilowatt-hour system with 13.5 usable kilowatt-hours of storage will take over 4 hours to charge at a continuous 3.3 kilowatts of power. For example: Minimal energy production, high energy needs. Time of use is not mandatory in all NSW. Many years ago now, Ronald Brakels was born in Toowoomba. Back. Privacy. Maybe this means they are really confident about their design but much less confident about their ability to actually follow that design and make a battery that lasts 20 years? But if you are going to install it in a hot place outdoors it is possible to bolt a little air conditioner that to the side ensuring it doesn’t conk out during a heatwave. This is already happening in Europe. UPDATE 1 October 2018: Mark in the comments said he had a datasheet for the sonnenProtect which is superior to the sonnenBackup-Box and he was kind enough to send me a copy8. At time of writing, information on their latest battery systems is not available on Sonnen’s Australian website. (This is how my system is). These batteries last longer and have a higher safety performance than most other lithium-ion batteries that are used in laptops, smartphones and electric cars. Sonnen battery systems now come in 5 different sizes starting at a nominal storage of 5 kilowatt-hours and increasing in 2.5 kilowatt-hour increments up to 15 kilowatt-hours. Do you agree with what they are saying? Even if you don’t go for the sonnenFlat deal, you are purchasing a solar battery that can cycle three times a day. Forget about batteries for at least the next 5 years. Meanwhile, sonnenBatteriegesellschaft is charging $16,500 for the same useable capacity. They installed the World’s first lithium iron phosphate home solar battery eight years ago and have since installed over 20,000 in homes across Europe, the USA and now Australia. Warranties | Terms and Conditions | Privacy Policy, Trained and accredited as sonnen Premium Partners, Quality, value for money products with warranties of industry standard or above. Its estimated subsidised cost is $6,800 and has 9 usable kilowatt-hours of storage. To explain its details and how the costs stack up will require a whole new article I’ll have to do in the future.

It makes you part of a virtual solar power plant which looking into the future could be the means of selling solar power to people who don’t have solar systems but want reliable, cheaper electricity than the grid will be able to provide. Below I’ve put the estimated retail price after the applying the subsidy. If they are confident the system will last that long they should give a warranty of 20 years, or close to it, rather than half that period. Using German technology and now being manufactured in Australia over its lifetime this battery provides double the kilowatt-hours of its competitors. That circle on it glows blue and whenever I come across a large one I expect to see Doctor Who step out of it. Again, this cost is without installation. All Rights Reserved For example, when my father is cooking he can easily draw over 6 kilowatts4. Hanging out for Fridays industry update…. The components are built into one top quality casing and perfectly attuned to each other. Cookies There’s a real lack of information on how well different battery systems perform under real world conditions. As the DC coupled hybrid 9.53 converts solar energy to AC electricity, which is used to power homes or be fed into the grid. Just want a straight answere , cost to install not thousands of dollars on top it seems a very simple connection. It is an additional unit that is used to complement the sonnenBatterie hybrid 9.53 system. sonnen - Energy Storage; Sonnen battery cabinet LFP2 The extension cabinet is used to increase the energy storage of a sonnenBatterie. The Sonnen system will cover the energy produced in the daytime. To determine whether the sonnenBatterie hybrid 9.53 is a cost-effective product for your system, will depend on a closer examination of your electricity needs. Here in N.S.W. If I was a battery installer I would definitely want Sonnen to clarify if they expect it to suffer deterioration during the warranty period. Use solar energy at night However, if you live in NSW, SA or VIC these states have a home battery incentive schemes in place. This way you have power from your powerwall 2 during the most expensive time 2-8 pm peak rate and 8-10 pm shoulder rate. In return you get all your electricity use — within limits — included in that flat rate. Sonnen’s 9th generation systems come in three different sizes as this graphic taken from their datasheet shows: If you think you will expand your battery capacity in the future you can get a cabinet that is larger than initially required. According to Tesla’s AU website, one Powerwall (13.5 KWh) costs $9600. And that’s what really matters, hey? The problem with the grid is the service charge which should be pro rate instate of a fixed tax irrespective or whether you use 10 kWh a quarter or 10,000 kWh. sonnenBatterie Eco vs. sonnenBatterie Hybrid. Since then from 10.3 0am till sundown our system keeps dropping out, only to start again, then drop out. So I’m confused. They are non-flammable meaning they last longer, as they can handle higher temperatures from a short-circuit or overcharge. These are without the outdoor enclosure, the sonnenBackup-Box, or the cost of installation. As a gas or electric water heater run often day or night to maintain hot water when needed, they are costly. Find local, MSC certified Solar Installers, “We were pleased at the prompt response, received our three appointments from solar companies within a couple of days.

You may have noticed on the datasheet information above that Sonnen says the design life of their system is 20 years but the warranty is for a maximum of 10 years. 1.6% efficient, this means that we will be getting a bill. If you are able to calculate the payback time of just the battery and find it’s able to pay for itself within its warranty period or even close to it, let me know as I would like to write an article about on it. Capacity & Kilowatt hours: The sonnenBatterie eco 9 has a capacity of up to 16kWh. If that is the case I apologize for that. And like other lithium batteries, its anodes are carbon. Its technical specifications, including its dimensions (which unfortunately only include space and not time) are shown below: “…protect the sonnenBatterie in excess of the nominal warranty period of the system.”. Your electricity will be covered by sonnen up to a realistic kWh amount for a monthly fee a bit like with a mobile phone plan. The battery suffers no deterioration in capacity. By the way I am not Dutch but have visted there many times and married one. The sonnenBatterie hybrid 9.53 has an industry leading 10 year/10,000 cycle warranty. But I also know Sonnen was offering installers special deals on it so it is difficult to say what it will actually cost you.

Unfortunately, batteries do deteriorate and most warranties allow for this. Griff is right – the good news – in most cases you can ring your energy supplier and even with a smart meter switch to single rate. The Chinese communist party (CCP) is an evil form of government and should not be supported.

As you probably already know, I get a credit on my electricity bill. There is a lot to fine turning ones home.
