Has anyone got the true cost of a single ZBM3/Gen3 unit with inclusions/exclusions?
The best I could find with a quick google was
"The last price we had for the ZCell (back in 2018) was around the $12,600 mark excluding an inverter and installation." from https://www.solarquotes.com.au/blog/redflow-gen3-battery-mb1817/

100% expected this CR/SPP per my July posts and can take it up if I wish to. The price asked is above my entry so I am cool on it especially as I think we are still in a bear market. RFX will only return shareholders significantly if it scales up. The cost of its product in comparison with alternatives is a big part of whether they will be able to do this.
