Still don't see the benefit of submerging and dealing with all of the engineering challenges that causes. At 240kw of power consumption, that level of energy density must be using some sort of forced air/water cooling system. So i

I think I would take the same advice as is given for someone handling a gun -- treat every gun as if it is loaded. Treat every wire as if it is hot. Unless you have a really good reason not to. Not doing so is putting an awful lot of trust

This is not correct for the majority of US households. Two of the phases DO NOT run to the house, a typical US household service is split-phase. The primary winding in the transformer at the pole connects between a single phase and ground,

A person without knowledge of what is inside of a wall or why it could be a problem may indeed try to use a 6" nail to hang their picture. There are plenty of people that don't understand(and probably don't want to understand

Yep, and when they work on hot lines, they treat them as such, using the protective gear you mentioned. I cannot think of a time that I saw a lineman working on a power line that was not shorted, without protective gear. Working on a hot wi

I'm not a lineman but am a generally curious person, which has caused me to watch and analyze their work when I see it. Any time I see them working directly on high-voltage lines, they connect a device that looks like jumper cables in-

The SolarEdge system I have targets 380v. At power up, it runs the string voltage up to 500v to test for isolation(short-to-ground) issues. It has a mode that can temporarily run the string voltage up to 1000v to meet testing requirements i

I kicked the solar installer out after he did the physical work, I did the rest of the provisioning and configuration after the inspections cleared and the meter was swapped. He was insisting on installing a cellular modem on my inverter an

You would have to constantly adjust the resistance of the element to sink the proper amount of power. Some inverters allow you to over-size the DC(solar) size of the system and indeed dissipate power in excess of its capability as heat. The

+1 to SolarEdge. I have an HD Wave and it seems to be a really nice inverter. They have some nice ones that can connect to a battery as well.

I have such an inverter(SolarEdge HD Wave)[1], but you have to specify a specific power level to throttle to -- and it requires some additional supporting hardware to measure what it is feeding the grid with, and still requires at least a s

This is something I struggled to understand when my system was installed. With the normal grid-tie systems, all of the energy produced by the panels must be consumed. If you are producing more solar energy than you are consuming, while ru

Another issue I just remembered. Even if the system is designed disconnect the grid and operate in off-grid mode, without attached batteries, things will be very dicey. You will suffer constant brownouts and blackouts as clouds and weather

Most solar systems are grid-tie, in that they synchronize their output to your local electric grid, and feed any excess power into that grid. They do this by increasing their voltage output until all power generated by the panels is consume

That's better, but I really got used to 16.04's method. It grouped the tasks, but a pause on the task group would open it and sub-subsequent alt-tabs would switch between windows inside the group.

I don't know if I would call all of them bugs. The non-registering clicks thing, yes. The rest...are likely just preference issues, difference in features, and intended behavior. Such as the lack of keyboard shortcuts in the alt-space

Spinning hard drives have a decent gryoscopic effect. Hold one while it's powered up and try rotating it in a manner that would change the plane of the platters and you will feel the resistance. Each time you do that, it puts a slight

I wonder why they are submerging these instead of just making them a floating barge. I can't imagine submersion is significantly better for cooling, the energy density very likely already requires a circulating water system, and the ad
