Ideal has been consistently saying they're not getting into the residential market because the numbers weren't there. And while I believe they meant that the business case for an installer or a home-owner wasn't strong to fund a solar+storage setup, it still seemed like a reasonable small (?) effort for them to release a sub-30kW inverter anyway, as they shouldn't much care about the ROI or financial viability of residential installations as long as they have acceptable margins on their products.

Here's an article that studied the financials of 4 and 6kW residential Tesla Powerwall installations in Australia. It's interesting to get the insight.

The conclusion was for Solar+storage using Powerwall and net-metering, the payback was 21-23 years. Payback for off-grid entirely, was 17 years. All calculated with Australian electricity costs, of course, which are higher that in the US (but similar to some European countries).

It's been a while since we've had news. I hope there is something good very soon.
