Re: Solar production numbers don't seem to add up.

Please make sure you have read the Outback power app notes on Grid Zero and a second one of Radian input modes. Grid Zero mode and the Grid always communicate with each other, daylight or nighttime. This cost in my system was 500 watts per hour, 12 kWh a day which is a lot. Even in full sunlight wit...

Re: Integration of third charger controller. In to a pre-wired

Okay, here goes: I have 3 FM60's all working in harmony. Using a Radian, the GSLC and a bunch of batteries. My batteries are in 4 strings, all 4 strings attach to a big copper buss bar. The leads off of the buss bar go to the inverter. I am in Grid-tie SELL mode. Now for my Optics RE settings: Mate ...

Re: Charge controllers aren't contributing to equalization

Mike, in three years I have never observed my charge controllers able to say product an output of 64 volts to equalize my batteries. If I want to equalize, I would use the grid AC and charger when the load is not from battery or PV and my batteries are full. In my case, my batteries commonly hit 58-...

Re: cloud-edge effects explained

I never used the word significant. To me, significant is more of a statistical term whose meaning is usually outside of the 95% confidence interval (ie. 2.5 percent of results at the top and bottom of the bell shaped curve, or that part of the curve which is greater than 2.0 standard deviations abov...

Well, as long as there is a spirit of improving the Optics RE milieu, the Summary screen display has buttons labelled "Solar" and "To Load". There are also buttons labelled "To Grid" and "From Grid". I propose the following which in my opinion would be an improvement in the labels of the buttons: "S...

Re: Output of Panels

I think in this post it is important for correct language to be used so clarity of what is being said is meant and understood. I'm really not certain of the PV definition of "output". I would say it means that if I put a voltmeter on the + and - of the panel, I can measure a voltage. So the panel is...

Re: Output of Panels

It seems to me that for old panels, reduced power output could be inherit in the silicon, in the solder joints on each side of the cell and between cells, in the solder joints between rows of cells, in the junction box, in the diode and in the wire connections of the junction box. This causes drops ...

After a week of torrential rain over 6 inches, we finally had a sunny day in the low 60's. My system is 3 years old. Cloud edge effect humming along today.

Re: heavy load causing voltage drop

So if I understand you correctly, you are not using the Phase Perfect device. Instead something like a gohz.com unit and it works okay. That's good to know because I often see a lot of saws and other tools in my area that are 3 phase for sale at good prices.

Re: Residential PV systems with batteries - UL-9450

One day a spider spun a small web. Low and behold, he caught a moth right away. He asked the moth how come he got trapped in the spider's web. The moth replied, that he was nearly blind and couldn't see it until it was too late to turn away. That got the spider thinking. What if he spun a really big...

Re: Pre-charge circuit

A couple of thoughts here. An electric motor has a large inductive current. For example a table saw, AC compressor and a refrigerator motor. Not much else has. And those motors are protected and aided by large starting and running capacitors that are energized prior to the electricity turning the mo...

Re: Where does the programming reside?

The Outback hub is not a "dumb" device and you cannot substitute any Ethernet switch or POE switch. It provides power to the outback devices and I believe also contains the onboard outback webserver with DHCP controller.

Re: Pondering Skybox system for off-grid application

My 2 cents during quarantine time. Only install PV and batteries for grid backup, to reduce utility bills, to produce clean energy, as a source of electricity during wind blown utility cutoffs or as a hobby project. Use a skybox if mounting outdoors, use a Radian if indoor installation. Know your lo...
