Powerwall vs Givenergy AIO - advice please

We're about to have solar panels + an EV charger (Zappi, probably) + a house battery installed, still at the quoting stage; BUT, we're unsure which to choose from the Tesla Powerwall or the Givenergy All-In-One batteries. we're already with Octopus.
Does anyone have experience of which they've found to work well, and ideally why it was good, please?

We had solar, GivEnergy battery and Zappi installed a couple of years ago and have been really happy with the whole setup. GivEnergy has a UK team who are actively developing/improving the product. The AIO wasn’t available when we got ours, but if it had been we would have opted for it.

We’ve recently swapped onto Octopus Intelligent Go. We’ve setup Home Assistant to charge the battery when Octopus issues extra slots so that the Zappi doesn’t empty the battery into the car. This was the only thing we’ve really needed over and above the standard Giv functionality – but good that the battery has the ability to connect in with third party systems etc. The Powerwall has similar functionality I believe and there are other ways to setup the Zappi so it doesn’t drain the battery.

The Giv battery integrates automatically into some of the Octopus tariffs and you have control over whether you want to discharge the battery to the grid (useful in the recent Octoplus sessions). Essentially its fairly flexible - as tariffs and energy use changes over time.

At the time of our install the Tesla battery was a lot more money. I know that the gap is now similar. We’re actually in the process of moving, so likely to be going through the solar/battery install again and will be considering both options – although I expect we’ll go for the AIO. While I know that we’ve not had any issues personally, like with all things there are some bugs which affect certain systems/setups – including issues with the state of charge figures. There is a really active Facebook group and community forum where issues are shared and fixed and again I see it as a real positive of their system…

The Tesla Power wall is still on old tech batteries whereas Give Energy is on LFP hence at least twice the life cycles.
Quote from Tesla Powerwall 2 - Spirit Energy


"The Powerwall battery cells are made from lithium manganese cobalt (LMNC). In this respect, it differs from many of the other home storage technologies on the market (and all of the other batteries which we offer), all of which use lithium ferro phosphate (LFP). In our view, lithium ferro phosphate offers a superior chemistry to lithium manganese cobalt.

LFP offers many more lifecycles (one lifecycle being a round-trip in and out of a kWh) – i.e. many more storage slots. Typically 8,000 – 10,000 lifecycles for lithium ferro phosphate, compared to 4,500 for lithium manganese cobalt. This means that each 'storage slot' costs a lot less for LFP than it does for LMNC.

It is surprising that Tesla has gone against the market norm in their choice of chemistry."
