... Under current rules the solar panels must be connected to the grid and if the grid goes down you are SOOL. It's not that the panels and inverter don't have the capability, the problem is that in order to switch to off-grid mode you would need a transfer switch and a generation source to sync the inverter to. Most contracts do not allow for disconnecting the inverter from the grid even temporarily and worse yet, the new mandates banning the use of fuels also apply to generators....
That’s a pretty dodgy answer, one which seems to attempt twisting what I said to make it sound wrong.
I never said battery banks with transfer switches don’t exist. Generac sells one right now(and there are others). What I said was that you cannot connect solar cells to the grid (through an inverter), selling electricity to the utility under Net Zero rules, and then use the cells during a power outage for consumption and to recharge the batteries. If you think otherwise post a link that shows a contract which allows this. The obstacles are not technical but rather legal/business ones.....
Grid tie solar is regulated at the state level and regs are very different from state to state. I did not address your situation specifically because I do not know Mass. rules. I can tell you however, that VT, NH, ME and NY allow interconnect with battery backup and a combination gridtie standalone inverter that conforms to IEC standards. I agree that legal issues are at play here.
Please point me to the regs showing it's illegal in Mass. After all, you are the poster asserting it. Back it up.
And check that quote "Under current rules the solar panels must be connected to the grid...". That is simply false. If a solar panel installation is not connected to the grid, the Commonwealth authority that regulates grid interties has no authority because there is no intertie.
I do know people in Mass. who are offgrid and have solar panels. One exception disproves the rule.
