DC Battery storage into Tesla Powerwall

[NikoV6]

Clearly, being an AC system PowerWall will not take DC directly.

However, as the DC generation from my solar array could be stored in a DC battery, then converted to AC by hybrid inverter. Surely its just a case of adding that inverter output to Tesla gateway in the same manner as the output of the current solar inverter.

Or is that noob talk?

Not an electrical specialist, I'm a mechanical engineer!

That would be my method of doing it.

PylonTech US5000 4.8kWh for £1650ish looks good value unless your research has found better?

When I was in the RAF, we used to joke where's the leccy - normally sitting on the nearest radiator!

I was thinking more along the lines of the 280A batteries in a series string of 16 and into a hybrid inverter.
For around £10K you should be able to get about a 54kWh battery storage and 2 x 5kW hybrid inverters.

When I was doing my apprenticeship we used to have a joke about what the favourite song of a Fitter was.
Although we had some modified lyrics to the original.

Hmm, could start off small and add to this then?

Can you link to where you could source please?

Going back to the original theme.

The problem with the 2nd AC coupled battery / hybrid inverter is getting it to work harmoniously with the Powerwall and stop them competing with each other.
