I tested my generator last night, for 30 minutes, full load test. I have 1575 watts of exterior outdoor lighting, incandescent. I tested dimming it from 20% to 100% in 5% increments and noticed no flickering.
My backyard uses old fashioned dual bulb flood light receptacles which have in them each, 2 Sylvania LED Night Chaser Dimmable PAR38 Flood Lights. They are 25w (250w equiv according to 'them') and I have 4 sets for a total of 8 bulbs back there. They did not show any sign of flickering but I did not dim them, forgot to.
My interior lights, mostly can lights all have LED floods in them. They do not dim, no flickering there. The garage has 4 foot fluorescent fixtures, 6 total units for a total of 12 bulbs, I think I noticed some flicker there but I can't be certain. Will try to look at them tonight. They are old fixtures, old bulbs so not sure I like them as candidates for a test. I have a 5 ton AC unit, it did kick on for just a little over half of the period, the car did NOT charge during it.
As for the side solar conversation:
My plan is to run a ground based solar array with Tesla Powerwalls to achieve the following goal:
Zero grid use during PEAK energy (Time of Use) period.
Reduce my OFF PEAK grid energy usage. I would 'like' to reduce it to zero.
I will 'sell' excess solar energy back to the grid but quite frankly could care less. It's not technically in the scope of the project. My utility provider is anti solar.
My average kWh consumption based on 18 previous billing cycles is 1875 per month. 442 per month on average ON PEAK. 1433 OFF PEAK. I pay $ 0.08568 off peak and $0.19325 on peak.
Phase 1 will just be 2 Powerwalls + Solar. I will rough out for a total of 4 Powerwalls to keep the Tesla engineering team happy, since they want 4 so I can sustain a 7 day continuous outage on Powerwalls alone. I have the 22kW Guardian still and will always have that in the equation though I will replace it with a liquid cooled model when that goes belly up. Phase 2, if needed will put more solar up and possibly another Powerwall since I have 1 EV vehicle now and expect that number to go to 2.
