We could but dream of that.. BUT .. the typical inverter is not where you need the diversion, and I BET that the authorities would frown on such a blatant attempt to prevent EXPORT.
There is no doubt that authorities RELY on Solar Exporting..
( The export Sensing needs to be at the supply end of things - The device is super easy to connect )
COST - YES but when you can use it to store a LARGE amount of energy, it is far cheaper than a battery..
( I am still undecided about batteries - Still procrastinating..

)
Even if you had Instant Gas - the cost of installing a water tank to be pre-heated by solar - is plain sensible..
I cut off the town gas and switched to LPG.. thus wiping out those "Service Charges"
Now I want to reduce the actual gas usage, and this is one way..
Internet and CLOUD connections.. well I hope that the system is not hackable, by folk looking for a back-door into my INTERNET..
