Capacitor in place of batteries?

[Naptown]

I am familiar with them. They are PbC batteries where the negative plate is a hybrid carbon lead compound. It allows a standard lead acid battery to to be discharged deeply, very high C rates, and greatly increased cycle life. It has some promise and there are a couple of manufactures just getting started making them most notable Penn'/Deka making a batch of them for a utility scale project. You can learn more here.

Orignally there were developed to compete with Lithium batteries for the EV market, but they will not fly because of the low energy density. However that is not important for RE applications. They cost slightly more than standard Pc, but much less expensive than Lithium. Sandia ran test on Deka, Axiom refused, and initial results were outstanding as Sandia estimates cycle life in excess of 15,000 cycle to 80% DOD. That could be a game changer.

15000 cycles / 365 cycles a year = 41 years.
that is one long lasting battery if it works out that way.

Well Rich as you know that is simulated and not real world results. Funny thing if it proves to be real, we will never see it.

No, but our children, or our children's children....
Q: Is it also a characteristic of a civilized society that they plant solar trees that they will not live to see fully grown?

russ just put up a new thread today concerning the PbC battery and the company that makes it getting a large contract for a trucking fleet.

The website for Axion Power also showed what looked like a large Grid Tie battery system mounted in a trailer called a Power Cube which seemed to be in use. They are not a high density type battery but will be able (according to the website) handle 1mw for 30 minutes or 100kw for 10 hours.

Maybe it won't be our children's children to see this technology.

Yes I think you were all correct! I have returned it to china and paypal will be putting through a refund this week. Have decided to spend a bit more and go with an Enasolar GT 3kw inverter that has a DC input of 100-600v, so I can series all 10 of my panels to 450v. Made here in NZ and comes with a certificate of compliance to keep it all nice and legal, not to mention also has built in Wifi for PC monitoring.
