@megopie technically you can buy an adapter that has two connectors, one for charging and one more, either a headphone jack or one more USB. But I agree with the sentiment, a second built in port would be neat.
@justanaveragejoeYou are right that this setup needs a DC-AC inverter often sold together with the PV panel and the inverter is designed for this purpose. It sort of rides on the sine wave from the outlet. Yes, this only works on one phase while the building gets 3 phases, but practically it does not matter since the meter sums all three phases.
There was some debate over the technical standard and meter type, German bureaucracy and lobbying!@bstix
@Wispy2891This is the main problem. The #OpenPrinter project is cool, but depending on HP cartridges breaks it. Unless the team has a source of 'compatible' cartridges which are not refilled HPs. Then, it depends on the price and quality of those.@ardi60
