Re: Caveat energiser
Unless the system is crap I hope that would not be the case, but you would certainly need significantly more battery capacity in the UPS to either be able to offload some of your demand during peak hours, or to backfeed into the grid without negatively affecting your own security.
The sad fact is that from a grid perspective most of the renewable energy is crap since it is unreliable and fluctuates to much both over shorter and longer timespans so that it becomes hard to keep the grid voltage / frequency stable.
