Anyone had experience with these storage systems..?

Read the Specs before deciding.

You will need at least 2 of them because of the maintenance cycles they go through periodically, 100% DOD looks cool, cost to life cycle benefit I'm not so sure the long term maintenance is another issue, it could be a long term show stopper, they use pumps and quite complex therefore they have multiple possible failure options.

ZONC.. indeed, but it got back b4 the post was locked.. :D

I know they are more complex, but I like the idea of charging the electrolyty, as it were..
And it seems they might be very serviceable, with the fluid replaceable. Etc.. ie. Most of the physical parts remain..
100% DOD sounds nice.. ie.. you can't accidentally destroy them..
Still not convinced on the value, but the technology seems perfect for a home installation..

Saw them again on Catalyst, last night.. along with other exciting systems.

PS.. listening to all the stuff on storage advancements, you wonder where the discussions on PV Service Charges and "Disconnection Fees", and compulsory Service Charges (availability) come from

Of course if the "gel" version is indeed as good as it looks on Catalyst then it could easily be the solution as long as it has the cycles, long term life, we can only hope.

I wonder if they will have inherent internal balancing or, will they need management electronics on them to ensure they stay nicely balanced to maximize the input/output with them over the long term life and maybe to enhance total life.

We'll just have to wait and see on that front.

Well we have been waiting to see for a good few years now.
Must have been 6 and 1/2 years ago that a rep first came to see me.

I must admit to not having looked at their site/specs for quite a while, but last I did they appeared to be comparatively inefficient, so you would need a lot more PV than if you had a LiFePO4 battery in an off-grid system.

In a home setting, a Redflow battery would sit on the ground as an independent unit, possibly near an air conditioner or rainwater tank. “We’re producing now a nice outdoor rated enclosure that looks attractive and gets the job done,” he said. The battery is the size of a bar fridge on its side.

Mr Hackett wouldn’t say how much the Redflow home battery system would cost. He conceded it would be more expensive than a Powerwall, but it would have almost twice the capacity, about 10 kilowatt hours. “We think our product is going to be a fabulous workhorse that’s going to run at least as long or possibly longer.”

Launching this month, but still some technical issues to solve:

Domestic 10kWh ZCell launched today, not much change from $20000!
