Their cover letter seems somewhat gung-ho. Quote:
"the two industries appear to be on the cusp of a breakthrough,
walking in lockstep towards a future where homeowners
have a PV system on their rooftop, a battery in their
garage and an electric vehicle on their driveway..."

Just a battery company trying to stay alive with Pump and Dump meaningless PR Kool-Aide greenies like to gulp.

Well I've got 2 out of 3, wouldn't mind having the last piece of the electric puzzle

tesla great for business

Hi All,

Since the big song and dance routine by tesla we have seen inquirys spike into storage, mostly from our existing customer base. So thanks Elon you have been great for business

I just read an article about Duke Energy installing a second 2MW battery system at one of their coal fired generating plants in Ohio. And they already have a 36MW storage system in Texas near a wind farm.

It looks like the battery chemistry being used Li-ion based because of the fast response needed for grid stability.

In their article they talk about 2 MW ENERGY storage. Do you suppose they mean 2,000 kilowatt HOURS?
Or maybe they mean an instantaneous flow of 2,000,000 watts of POWER?
Its not good when the biggest co doesn't even know how to properly describe energy or power. Bruce Roe

Like in this forum people seem to mix up KW and kWh a lot. Whomever wrote that article either made the same mistake or those units are rated 2MW but failed to provide a mWh discharge value.

I have also seen some reporting mix up the DC and AC rating of a large array. You would think they could get that right.

which inverter to use if interested in PowerWall / storage

would the SolarEdge inverter be good for the PowerWall?
or string or
micro inverters?

360 volt inverters thar do not exist.

Answer is yes, sort of. Solaredge has announced they will offer a retrofit to existing customers apparently there will be some differences.

Looks like SE is working hard with Tesla to get some traction on the energy storage system. Unfortunately the cost for even a retro fit of the Interface and Powerwall is still beyond what most people will find any ROI.
