Already had a new 12.1kWh PV system. After much research (unfortunately, not on this forum) comparing one PW2 with a natural gas generator, I decided on the PW. As I have net-metering, the PW's only purpose is as backup---same as the generator.
For the same net money as one PW, I could have installed an 18kWh NG generator that would have easily powered my whole house. I decided the limitations of the storage of one PW would be outweighed by the unlimited off-grid solar capability, assuming sunshine.
Putting aside the 50F temperature issue, which is not applicable to me as I installed in conditioned basement space, one week after installation, I'm learning the Tesla marketing is extremely misleading and I am regretting the PW.
After running some power-outage tests, I discovered there are extreme limitations on off-grid solar power with the sun shining. Counter-intuitively, the more the sun is shining, the less one can use the solar capability due to various limitations that one can read about elsewhere on this forum. Talk about crazy.
My installer, a relatively new partner with Tesla, was not told about these restrictions during Tesla training and is searching for a solution, i.e., some way to divert the excess solar and dissipate it, such as with a capacitor. I'm guessing from what I've read on this forum, there is no such capability. Tesla markets this simply as your PV system will work off-grid with sunshine. No little asterisk about the restrictions & complications with those restrictions.
That is my question; is there any way to divert/dissipate the excess solar while off-grid in backup mode so that the PV doesn't shut down? Thanks.
