" So this battery is almost 33 times bigger than our zbm @10kw"

Interesting as the physical size of the batteries doesn't seem very large so they must be very energy dense which leads back to my question if existing stack is stressed or can cope with increased size of tank and subsequent increase in capacity. Peak output may not change but duration / capacity may obviously increase .

I haven' looked hard enough to find full dimensions and weights and haven't seen quoted 320kw either.

I did similar back of envelope and concluded similar . Installed costs inclusive of design etc is only way to have realistic idea of what different systems cost and how they scale.. Unsure what warranty or power uptime, power output guarantee another small company can provide to get a Guernsey in tenders.
Still need to resolve if that costing includes owning the liquids up front or renting them as that makes a obviously huge difference on running costs.
