Solar Panel & Battery Quote Advice

@Screwdriva Just thinking, but an alternative to reducing panel numbers, could be to limit the output of the Tesla PW3 (if chosen) to the DNO limit. I know that would mean clipping when the battery is full, and generation exceeds the limit, but may be acceptable. And of course, clipping would be less (and less) in the winter months.

@McKnze21 This may sound odd, but as the panels themselves are the cheap part of PV installs, it may be worth considering. Happy to bore you with more thoughts and examples if interested. But as Scredriva says, best to find out what you can, and can't do first with the DNO.

The PW3 automatically self limits generation based on household demand -> battery recharging -> max permitted grid export in that order. As an example, an 8kWp array with a 4kWh export allowance will generate only 4kWh + base load + any appliance consumption only, even in ideal conditions, assuming the battery is full.
