Fully Charged Presents Its Own Tesla Powerwall 2 Installation – Video

SEP 3 2017 BY MARK KANE 14

Fully Charged’s Robert Llewellyn upgraded his home solar array this Summer from 2.2 kW to 5.5 kW, and also added an energy storage system – specifically, the Tesla Powerwall 2.

And as such, a new episode presents the installation from a customer perspective in the UK, including an overview of the whole set-up, a Tesla application demo, and a talk about energy storage.

The Tesla Powerwall 2 is rated at 13.5 kWh,with 5 kW of continuous power output, which is one of the most energy dense and price-competitive ESS systems on the market.

The Tesla ESS (well, really any energy storage solution) offers a better utilization of site-generated renewable energy, and is another step that lets one be more independent from the grid.

However, according to Robert, having energy storage (as of today) as part of the equation, will extend the payback period over just a solar installation. Hopefully in the future it will be more affordable, and bring also some savings; a trend which we have seen over the past few year.

In 5 or 6 years time when these battery prices are around half of what this is at the moment will make it a reasonable buy, sadly at the moment this is a non starter financially.

It’s over $10K for one battery to be installed here in the UK according to Tesla’s prices.

In my Opinion The Unit is too close to the floor ..If the Basement floods The Power Pack will be destroyed..

Here is a gentleman from Oz who also got a Powerwall, however he can also island his system and use it for backup. I like his take and low key approach 🙂

The Powerwall 2 is your best weapon to fight off predatory net metering rates that were designed by the utilities to negate home solar. It allows you to store up to 13.6 kwh of excess solar generation and use it when the sun goes away instead of buying much more expensive power from the utility.

Here in the US the Powerwall 2 is certified to operate as a backup power source when the grid goes down. What’s even better is it simulates the grid to your solar inverter so your solar operates when the grid goes down!

I live in the UK and as Fully Charged pointed out power cuts are super rare. I have not had one for atleast 10 years.

Exactly, and back up during outages like hurricanes, tropical storm here in FL. Makes sense.
Does it qualify for 30% Tax Credit if adding it to existing SolarPV…? That will make purchase/install more attractive.

That’s weird that currently you can’t store cheap grid power into your battery, during low solar days.
I suppose because that’s the way the utility wants it, because they don’t want storing their cheap power.

What do you mean? You can store power from wherever you just can’t sell it back to the grid if under net meeting.

The net metering is a safety issue atm. There is a risk of Natural Grid workers having the battery discharge into them due to lack of upwards isolation.

Planes are in place to develop a smart grid and solve this problem but it has a long way to go.

@ffbj,
agreed those were my principle takes from the video.
1) You can’t pull from the battery when the grid goes down…ie it doesn’t provide emergency power

2)You can’t charge the battery at night with cheap electricity.

Not too good IMO

You can use it just like you would use your generator…otherwise, get off net meeting or off the grid altogether. There needs to be a safety put in place so when the power is out and workers are doing their thing your battery doesn’t shoot power back into the grid. I can’t imagine this is anything complicated but needs to be imposed as part of instal.

V2H / V2G might make a lot more sense if you have the right set up including Solar Edge’s integrated charger.

There are actually many providers out there that offer different ways to store electrons converted from air motion or photon collisions:

They only hinted at it, but apparently Robert cannot have ‘net metering’.

In NY State – we can’t have battery storage if we subscribe to Net Metering, but then a battery would do no good since most of us don’t have time of day metering.

British electricians will have to chime in here, but I noticed the ‘mains’ switch was labeled N and L – So I assume this is an 80 ampere 240 volt single-phase ‘Consumer Unit’?
