The Tesla Powerwall 2 is due into the UK very soon, demand is already outstripping supply!
Following the launch of the Powerwall 2 back in October 2016 anticipation has been very high but technical information has been a little scarce. I hope to resolve at least one of those issues!
I think I can safely say that the consensus in the industry is that the Powerwall 2 will revolutionise the way we consume electrical energy. The original Powerwall is a fantastic product and is a great way to make the best use of the excess solar electricity and to even out the consumption over the day. However, its power range is limited and has been found to be a little lacking for medium and high energy users, it was limited in the features it offers and there have been issues relating to the complexity of the installation.
The Powerwall 2 is only available in the UK as an AC coupled unit, the DC version will not be supplied in the UK. The Powerwall 2 offers 13.2kWh of storage capacity, double that of the Powerwall 1 in a case which is similar in size and more streamlined. It can be wall or floor mounted, with the ability to stack and control up to nine units. Amazingly, for a product from a company with an exclusive reputation the Powerwall 2 has one of the lowest cost per kWh of storage on the market. Other products may be cheaper but they do not have the same capacity or offer full ten year warranties.
I believe the AC Powerwall 2 will have a significant effect on the Solar and Energy Market, for these reasons:
1, It is compatible with all existing solar PV systems. It has an inverter integrated into the case, which has a charge and discharge capacity of up to 5kW, though this is initially limited to 3.68kW to satisfy UK network requirements, I'll discuss this in more detail later. The battery connects directly into the fuseboard/consumer unit and has a wireless energy gateway to control it and provide online monitoring through a Tesla web-portal. The Powerwall 2 is a self contained independent unit which works seamlessly with your existing inverter and solar panels.
2, It can charge from the grid when electricity rates are low and discharge when rates are high. It is not feasible with domestic sized PV systems to expect a full charge from the solar panels every day, all year. By taking advantage of economy 7 or other similar off peak tariffs it is possible to top up the battery at the lower rates and discharge it during higher rate periods. Reducing energy bills further and supporting the supply grid at times when it needs it.
3, It could be used as a backup supply during power cuts. It is possible to purchase an automatic backup supply adaption kit for an extra cost, which will ensure you still have power in the event of grid failure. This option does involve extra equipment and electrical works to ensure the system remains safe and to G83/G59 regulations.
Pre-Ordering Information
Powerwall 2 will be arriving at the beginning of April. We have received a great deal of interest in the battery and are expecting a rush and also possible stock shortages.
We are now able to pre-order the units directly with Tesla for a £400 deposit and get them allocated from the first shipment due into Europe. The advertised cost is £6,350 for the DC version plus the cost extra SolarEdge equipment required the higher priced AC version is not yet advertised by Tesla. We are pricing the AC versions at £6,999 inclusive of installation and additional equipment.
Tesla are also taking Pre-Orders through their website at www.tesla.com , when an order is placed you will receive an email with a reservation number in the format EN-1234567, please forward this to myself at matthew@ctsrenewables.co.uk and it will be allocated by ourselves as a priority installation.
Thank you for taking the time to read our newsletter, more information on our products and services can found on our website www.ctsrenewables.co.uk or you can call our office on 01623 422254.

Tesla Powerwall - Options, Price Increases, Long Term Battery Pricing, Tesla Rumors Debunked!
1: Tesla Powerwall Options
Working is Partnership with SolarEdge and SMA, Tesla have been able to configure the Powerwall to enable compatibility with ALL INVERTER MANUFACTURERS. Upon its release, Tesla Powerwall's were only compatible with PV Systems using SolarEdge Inverters.
Of particular interest to SMA owners is the AC Coupled solution, the "SUNNY BOY STORAGE 2.5", the battery inverter can be installed or expanded in any location, at any time. The Sunny Boy Storage is a true jack-of-all-trades, one that uses high-voltage technology to make it cost-efficient and light weight. It also uses just a few components, because the most important functions for intelligent battery management are already integrated. It can be combined with numerous types of energy: PV, wind energy, combined heat and power plants.
SolarEdge have their standard DC coupled system which is compatible with most existing pre-installed SolarEdge inverters. In addition, SolarEdge have created an AC coupled solution as part of its "StorEdge" product interface by re-configuring their tried and tested, SE-3500 inverter as a dedicated battery inverter.
Both AC Solutions are compatible with almost any other existing inverter, and any battery storage system will work with FEED IN TARIFF AND EXPORT PAYMENTS.
2: Revised Typical Installed Prices:
In the short term, to generate interest CTS Renewables Ltd were able to offer the Tesla packages at prices significantly lower than the industry average for early adopters, however due to changes in exchange rates for both Dollars and Euro's alongside the slower than expected battery price reductions, As of 20/08/16, we can no longer offer the rates provided in previous emails and correspondence.
£4,499 - Tesla Powerwall to connect into existing compatible SolarEdge Inverter.
£4,799 - Tesla Powerwall to connect into any other inverter using the SMA or SolarEdge AC Coupling Solution
3: Long Term Battery Pricing
There has been a great deal of discussion on forums, message boards and within the industry about significant reductions in battery pricing in the near future. At a recent event attended by the BBC's technology reporter, Dave Lee, at the new Tesla Battery "Gigafactory" which is due to fully open in 2020, Elon Musk discussed potential battery cell savings of up to 30%. Which is a significant saving but it needs to be put into perspective.
Firstly its four years away and will no doubt be phased over that period. Secondly, these are expected savings for the battery cells, and not the other components which form the battery and its installation. Other costs which are not likely to change significantly include, the housing, US shipping, import taxes, UK delivery, wholesaler margins, other components such as cabling, SMA/SolarEdge battery inverters, and CTS Renewables installation cost. With all the other aspects considered I would expect that a 30% reduction in cell cost could only result in a 10-15% reduction in overall install cost. Finally, Non of this takes into account any additional price increases expected by the poor exchange rates with the Dollar and Euro.
This is vastly different from expectations of up to 50% reductions in the coming few months, as discussed in forums. I was expecting more significant changes and sooner, but it would appear that they will be much more conservative. I do however stand to be corrected!
4: Tesla Rumors Debunked
There have been a few articles recently in Tech Magazines and blogs regarding a Powerwall 2 which will be more powerful than the current Powerwall. According to my discussions directly with Tesla the rumors are groundless.
The only revision to the Powerwall is its newly released compatibility with the SMA Sunny Storage 2.5, any discussions regarding extra capacity is confusing its original advertised capacity, which was revised down to allow an advertised Depth of Discharge of 100%, or their 10kw backup version which has a different configuration.
CTS Renewables Ltd are able to offer alternative storage solutions from LG, Samsung and we are one of the few installers accredited to install the Tesla Powerwall. Follow this LINK to read more detailed information on battery storage systems from our latest information flyer.

Inside the Powerwall is a single self contained battery pack which you will find in the Tesla cars (which also have more packs). To upgrade the Powerwall would mean a change across the entire product range. Any near future revisions will be aesthetic to the housing or to the wiring centre to ease installation of the equipment.
