Additional Battery options

Hi all

My current configuration:
10 * AIKO 445 Wp SE; 10 * AIKO 445 NW (total 8.9 kWp); GE 5kW Hybrid; AIO 6 kW with gateway (DNO restricted to 8kW)

The capacity of the battery is enough for our current energy consumption as we currently heat on Gas and do not have an EV.

I could do with some additional power output to meet peak power demand (although this is not that much, mostly the shower which is 7.2 kW) and additional storage now would not likely be needed, but with thinking about the future it is likely that an EV will be in the mix and possibly ASHP later (especially if gas fired systems will no longer be available).

So my questions are:

  1. Is it worthwhile getting an additional battery now (no VAT and "free" EV charger)?
  2. I've been led to believe that DC-coupled batteries will not work with the AIO, so (if true)
  3. What, if any, GE AC-coupled batteries work well together (no cross charging for instance)?
  4. Assuming the DNO kept the 8kW export restriction, is it possible to configure inverters to restrict export but allow the whole power to the house if needed. So if I got another AIO 6kW could I have upto 12 kW power for house?
  5. What other considerations should I make?

TIA

EV isn't really relevant to storage planning - you'll almost certainly be charging that from grid (at off-peak rate). Unless you're also looking into a bidirectional system so that car is actively contributing to overall storage.

I think multiple AIOs can now be installed together.

DD I think multiple AIOs can now be installed together.

I understand that may be the case. Is that the only option tho - I can only couple another AIO to the existing one?

DD just had my second AIO installed, it’s in “beta” but can confirm it’s working.

For Item 4: The G100 settings can be configured to limit Export to your DNO limit without restricting the power available to your house. This is installer or GE controlled config though so not seen via portal remote control.

Hopeful Thanks - that is useful to know - one less thing to consider.
