v*a=w

so ? * 628 = 1,000,000

you do the math part, I'm lazy

Me too, that's why I want it in the article.

I hate how battery systems are rated. They never give the full picture. "This is a MW system" cool, but how much storage?

[–] moonshadow@slrpnk.net 6 points 22 hours ago (1 children)

It's in MWh, what more do you want?

[–] huquad@lemmy.ml 1 points 3 hours ago

Many articles leave that out. The headline for instance only lists Ah

[–] WhiteOakBayou@lemmy.world 3 points 23 hours ago

Yeah, I really want to be impressed and am sure I will be. Just give me the specs

Ah is not a good unit for explaining capacity, it's better to use Joules. Ah is better suited to throughput because it informs the maximal load that can be applied.

Agreed Ah are bad.

MWh are equivalent to J. Specifically 1MWh is 3.6GJ

Big cells aren't necessarily good... if something goes wrong that's a lot of energy being impacted. If a cell goes bad, that's a more expensive repair. I'm sure there's other issues as well.

It can save on initial costs though in various ways as well.

There's going to be some equilibrium where size, cost, safety all converge

When you build your battery farm, report back and tell us about the size of cells you chose.

Those look like Retro Encabulators

I feel so betrayed.
