I've already got solar. I've been told that when I get my next 8 panels I'll have to upgrade my inverter anyway

I'm in the same boat - going to get the MyEnergi Libbi battery when the time comes. It would appear to provide the best specs and compatibility with existing high voltage systems. Given their focus on smart tariffs, I wouldn't be surprised if the battery interface is remarkably intuitive. 

I phoned them up about this. Their largest inverter is a 5kW one

I said I plan on getting 8 more panels, so would need a 6kW inverter, as theirs would result in some clipping. I asked if they've got plans to have larger ones, and they said they don't currently have those but it's likely. They also said it hasn't truly launched yet anyway 

They did also mention that it has "full third party compatibility" so you could still use any other inverter out there, and their batteries would also still work

Did you ask about using 2 smaller inverters?

I didn't tbf

The rate of charge or discharge is determined by the inverter - conversion losses. A 3.6KW Inverter for example can only deliver +- 3.4KW at 96% efficiency. but realistically 3.2KW and then you have to factor in the C. rate of the batteries themselves. Never believe what manufacturers or resellers tell you. The figures are all massaged at higher values and like car mpg never attainable outside of perfect lab conditions.

So realistically if I've got 15 kWh worth of batteries and a 6Kw inverter, I'd probably be able to pull say 5 kW during plunge pricing? Ie :, 15kw would probably be five lots of three 

Hi

Take care, from earlier posts you mentioned the price plunge as being for 30mins for calculations .... in which case the ~6kW inverter in your example would deliver (say) ~5kW of power to the batteries for 30 minutes, so only ~2.5kWh of energy to the batteries themselves (before round trip efficiencies etc) in any one 30minute timeslot ...

Is this what you're thinking ??

Their Zappi and EDDI are not Octopus IO compatible in their own right.

This is correct. Bear in mind that your max theoretical generation will rarely be what you achieve in real life. I don't think I've ever hit 3.7 kW despite having a 4kW bifacial system. 

If I ever needed a battery, a Powerwall or Libbi would be my go to solution as of today.

Why not solax? Both the solax inverters and batteries "work with Octopus"
