Panasonic launches lithium-ion home storage battery system

 

Panasonic New Zealand has today launched its first Lithium-ion home storage battery - a clever system that can sense and store excess clean solar energy to power the household in the evening once the solar system has stopped producing.

This smart battery system provides a revolutionary and environmentally responsible solution to use solar energy on demand. New Zealand already has more than 8,000 homes with solar panels and this technology gives owner’s freedom to choose their energy source, manage their energy use and costs, in addition to providing an extra layer of critical energy security during power outages.

Panasonic’s Home Storage Battery system also offers a unique solution for New Zealand energy distributors. The batteries can be remotely controlled by an aggregated service provider, including utilities and energy communities, to reduce grid infrastructure expenses and better manage energy usage at peak times. This feature will help stabilise the grid by reducing solar system export during low demand times and supply it during peak times, such as in the evening. Many stakeholders and interested parties such as Transpower are investigating technologies to help them better manage existing infrastructure and Panasonic are perfectly placed to help with this easy to install and scalable solution.

 

Panasonic New Zealand’s Managing Director Stewart Fowler is excited by the growth and use of solar power systems in New Zealand and is proud to be at the cutting edge of the exciting new technology of home storage battery systems, which is widely regarded as the missing link to truly fulfil the potential of solar power systems.

“For the thousands of Kiwis who already generate their own solar power this is a dream come true, so we’re incredibly excited to bring this solution to New Zealand. We want to encourage Kiwis to take control over their power. The Panasonic Home Storage Battery System in conjunction with a solar power system could help an average New Zealand household to reduce their power purchase by up to 60%. We believe this is the way forward for sustainable energy consumption.

“This system isn’t limited to those who have solar panels. Consumers can use it to take advantage of favourable power prices during off-peak times or as an emergency power source for critical appliances. Energy providers can use it to meet fluctuating energy demands by using our smart demand response solutions, without having to invest in further infrastructure,” says Fowler.

Panasonic is a world leading lithium-ion battery manufacturer and for the past 40 years has been investing heavily in research and creating innovative batteries that provide a stable power supply that is reliable, high quality, high performance and safe in extreme conditions.

The slim home storage battery system looks similar to a heat pump outdoor unit and is a low-maintenance, standalone unit that can be installed inside or outside the home. Though this battery is designed for the residential market there are also major benefits for power retailers and energy distributors.

These utilities can reduce demand on their resources during peak times and provide savings to the consumer, along with providing back-up to run critical equipment during a blackout.

Energy distributors can use this as a cost effective alternative to increasing grid infrastructure for scale-ability in meeting fluctuating energy demands, such as a cold winter’s day when all households are running heaters and electricity demand is too high for the grid.

“Including the home storage battery system into new home building costs just makes sense for our future,” says Fowler.

No pricing? Don't imagine it will be cheap though.

Quick and drity calcs put it at around 50 cells of 60ah usable so say 30% DOD they will be 90ah cells. Around $6k USD retail for the cells. I'd say landed in NZ you'd pay $10-15k





Most problems are the result of previous solutions...

Seems to be the way of the future. There's another thread over here about the similar sounding Tesla Powerwall, and another here that turned into a discussion about inverters. From what I remember of 5th form physics, solar and batteries are DC but everything in your house is AC (or at least expects AC to turn into DC). You therefore need an inverter to turn it into AC.

 

 

 

Hopefully that's right. I really think the future of power is micro-generation at point of use - we're just waiting for the battery technology (and pricing) to catch up.

Wonder if your insurance company will want these batteries store down the end of your garden??

The more popular option presently is direct online solar, which works well if you can shuffle your loads to the midday period.

 

It's an ideal match/off set to air con heat pumps though, as the more summer cooling you need, the more power you are generating at the same time.

 

 

 

Batteries are a more comprehensive approach, but they do really up the anti, initial install cost, size and complexity and maintenance/upkeep wise.

 

The vibe at the EMANZ conference last year was that New Zealand consumers were looking for ways to supplement their grid supply, rather than completely do away with it.

 

 

 

Most of these additional systems will require a change to your meter, though the electricity companies will not buy your energy for a particularly good rate.

 

It's better to forget about that revenue stream and concentrate on perhaps 'earning' enough to cover your monthly line charge for example, focussing on using as much of the power that you generate instead.

I would be VERY surprised if this wasn't a fail-safe type of lipo chemistry like lifepo4

The title states Lithium-Ion batteries that are common in consumer electronics, as used in cell phones, laptops, power tools, to electric vehicles.

 

I would happily install this setup between my solar inverter and meter board, outside on the south side of my house.

 

The main issue is affordability, which is currently unknown?

The FAA would differ on the safety of these batteries.

Which is why, 1 major laptop brand is no longer bringing in replacement laptop batts to NZ !!!!!!
"Cant airfreight them in" was the excuse given, not much help to those needing a new laptop batt (I bought a clone batt instaed)
I guess some major companies have never heard of shipping via boat (which is still allowed for batts)

Agree that there are certainly safety concerns with all Lithium batteries, the main problems I know of are with cheap Lithium Polymer Batteries used in toys.  I have experienced problems with poor quality and take all the recommended precautions with correct balance charging, safe storage and disposal.  There are restrictions on air transport and package for shipping now.

 

Better quality Lithium Ion batteries in cell phones, tablets and laptops are all around me at home and work, with limited concerns.

And as I have said before, Using a hot water cylinder to store excess solar production is far cheaper. (on a $$$ per kW/hr of storage basis) And more reliable and if installed properly extremely unlikely to explode. (Plumbing codes require a combination excess temperature / pressure relief valve, and a separate excess pressure only relief valve to be installed. And the thermostat has a manual reset over temp cutout as well. So 4 things need to all fail at the same time for a modern properly installed cylinder to explode.)

 

 

 

And that battery system has a max output in backup mode of only 1KVA. Considering a normal power point can provide 2.4KVA continuous. (and alot more peak) Having only 1KVA available will be extremely limiting. Depending on what the peak output is, you might not be able to run a refrigerator from it. And very unlikely to be able to run a water pump. So for most use cases, a hot water cylinder is still better. And get a generator instead for backup power.

Its not really for running gutsy appliances, the real benefits come from being able to sell back the power at peak rates, instead of just when its sunny.

The buy back rate is wholesale, so any system that revolves around that intention is quite flawed.  Maybe earlier on when you were paid closer to your retail cost, but the power companies soon shut that down.

Better approach in my opinion is to go direct online solar (no batteries) and aim to cover your monthly line charge only via selling back power, and schedule your power loads to the middle of the day.  Simple timers on your DHW for example will ensure this is only heating during the day, and delay start timers on dish washers and washing machines should push these into the self generation part of the day, after you've left for work.

 

 

 

Batteries can be added to this type of system at a later date, but direct online is a good low maintenance and cheaper place to start to get your feet wet.
