Redflow Batteries


Marc

Recommended Posts

I've been looking more into adding batteries to my system lately and discovered Adelaide's Redflow today, with an interesting approach to storage with zine-bromine.

Anyone come across this or no any more about it? There's a video of Simon Hackett who was interviewed by Fully Charged on YT that offers a bit more insight.

I'm a shareholder and I was very keen on adding one at home, but, boy, are they expensive for home use! They are selling well for remote use situations like phone towers, particularly as they are so heavy they are virtually unstealable, as well as not being flammable.

Anecdotally around $17k installed with inverter etc. Will be interested to hear actual price if someone has one at their place. Issues are poor round trip efficiency, need an additional inverter in conjunction with the battery, they need down time to do some sort of maintenance cycle (not a problem if you have two connected as they self manage so both aren't off line). On the plus side, they should last twice as long as a lithium battery, can withstand hot environments (i.e. Australia), they don't use rare earth metals and can do 100% DoD without damage. If I could afford one and had a 20 year time horizon, that's what I would buy. In reality though, I think it will be V2X for me as soon as its available.

Interesting feedback that almost justifies the higher initial outlay, thanks.

That price puts it out of contention for me, but right now I'm focusing on using up as much of the excess locally (EV charger and Pool Heat Pump heating via diversion) instead of feeding back into the grid. If I can get that all running efficiently, and there's still surplus I may revisit batteries I think. I guess the more patient we are buying into batteries the more cost effective it will be.

Hi Professor,

I believe its actually their Gen 3 model. Remember reading somewhere that their recent capital raise fell short putting the future of the gen 3 in question. Supposedly a 30% price reduction if they can get it to manufacturing. That's all form memory, so some details may not be quite right.

RFX seems to be making gains now, particularly with exporting to other countries.
I bailed out of my shares for greener pastures, but I might regret that decision soon.

    • Hi Thanks for allowing me to join the site. I have a real passion for saving the environment from fossil fuels. I hope to do all I can to save our beautiful planet through spreading the word of recycling and renewables. 
    • Zappi itself works great ... it's the software side of things that definitely needs some work. I remain hopeful and continue to work through it.
    • How are you finding the Y? Everything you expected? Blows me away how many you see on the road now.
    • We've just bought our second home battery. The first one, a lead acid gel battery, has reached EOL. We've replaced it with 4x 3kWh GenZ LFP batteries. Each module has its own BMS, so if one module fails, the rest of the battery won't - vital when it's an hour and a half drive for our installer to fix the problem. It's connected to our 9kW of roof panels, DC coupled through a Selectronic SP PRO inverter. The system needs to be reliable as it powers our electric pump for our roof sprinklers, but as an added bonus, almost all our power bills are car charging power imports. We have a Tesla EVSE, but it's controlled by an app called ev.energy that only charges when Amber prices are low.
    • That's not good to hear; at least the Tesla EVSEs work!
