RE: Long Awaited Batteries Arrive.

Those OPzV's still have acid, no? My FLA's have lasted 15 years in a similar application as your new ones, and I expect them to last just as long. My point was, in cycling applications, acid chemistry batteries (which your OPzV's are) will not last as long as lithiums. Of course, the jury is still out ...

Impressive. I have both FLA and lithium banks in backup applications. Rolls 12 × 2KS 33PS, 24V, 41kwh @ C20 (20 kwh usable at 50% SOC), 2007 vintage, and Simpliphi 3 × 3.8kwh @ 48V, 2019 vintage. The Rolls bank cost $7700 in 2007, the Simpliphis cost ~$7500 in 2019. Considering their current ages, I ...

I have 15 years experience in clean energy, preceded by 32 years with the dirty kind (coal burning electric generating plants) so I have perspective on both. Since my "conversion" post retirement in 2007, I've installed 16.5kw of PV at my residence, and as a member of my local ASES chapter, Green Energy ...

The utility can have no idea exactly how much energy you are exporting to the grid unless export exceeds import. Otherwise they can only compare your historical energy use to whatever it is when your array is connected, and if the difference is large, then decide whether to come after you for connecting ...

When I put my first 1,440W array up here in Ohio in 2007, my utility gave me a net metering permit but left my old meter, one of those spinning disk types. I was still able to sell back to grid but never very much. It wasn't until I added another 6,450W array that they changed out my meter for a bidirectional ...

"I do have one question. When the Solar City system was installed, Oncor required that the DC to AC Inverter would turn off the solar power if the grid power went off.

I'm no expert on Fronius inverters but I noticed in this video https://youtu.be/NDTMe6nbGQE, one of the screens has an option to set the "MPPT2 start voltage". This is a shot in the dark but if you can compare the MPPT1 & MPPT2 start voltages, perhaps you'll find they are not the same and you may have ...

Hi John - I'm curious, how is your system different from what is currently offered by Tigo (and others probably)? I have Tigo optimizers on every panel in my garage rooftop DC array and today the optimizers provided an additional 1.13kwh of energy that would otherwise have been lost due to shading. ...

I guess I'm lucky since we don't pay anything additional for being grid-tied here in Ohio, probably because there's not as much solar penetration here as in sunnier states. That will probably change as more people adopt solar, though. ------------------------------ Mike Curran Retired from (dare I say ...

One thing you guys seem to be overlooking is that you are using the utility's wires to transport your sold/exported energy to your neighbors. If you want to receive full price from your neighbor then consider running your own wires to your neighbor instead of using the utility's. Then you would get full ...

William, is that 40kwh at 50% SOC? If so you got a great deal. If not, STILL a great deal! ------------------------------ Mike Curran Retired from (dare I say it?) Fossil Plant Mgt. joacchim57@gmail.com ------------------------------

I had one of those diverters before we abandoned our electric dryer in the basement. We also only used it in the wintertime, but our house air tended to be very dry then, so the vented dryer exhaust helped rather than hurt. ------------------------------ Mike Curran Retired from (dare I say it?)

@Stu Besnoff - Although I agree wall warts waste energy and disconnecting them when not in use is a good idea, when you consider that if your electric dryer runs 4 hours per week, over the course of a year that's equivalent to about 100 wall warts, you're better off concentrating on large loads like ...
