I am again messing around with trying to power my data center off solar power,, this time with way more luck,, but without a clear idea of why I have more luck.
Looking at the sinus wave of the AllPowers R2500,, I see nothing out of the ordinary...

Hello Morton. The hotswap psu modules have a 12 volt rail. You could try making an adapter out of a defective power supply and running it directly from 12 volts. A DC DC UPS in between and you're done. Then you don't need to convert DC-AC up to AC-DC down.

@MyPlayHouse 4 часа назад

12volt server :-) never thought of that,, I do think the server will refuse to start with out all the control signals from the PSU.

@zackkast 3 дня назад

the power station has a floating ground you need a neutral to Earth Bond on the output

@MyPlayHouse 3 дня назад

How would one do that..

@woutrombouts9506 3 дня назад

@@MyPlayHouse you could use an earthing plug on a regular house socket to connect the ups chassis (or sometimes they have a grounding screw at the back) with ground, this way your UPS and servers are still properly grounded to your house while power is coming from the power station

@zackkast 3 дня назад

@@MyPlayHouse assuming all sockets have continuity with each other the most simple way to bond neutral and Earth is to use a male plug with a wire from the left pin which is neutral to the center pin which is Earth to create neutral to Earth Bond if you don't understand what exactly i say just search neutral to Earth Bond plug or Generator Neutral Bonding Plug and you going to find a solution btw after doing that be careful how measuring with the output with the oscilloscope I hope I helped

That's why it worked with osciloskop connected. Bet if he disconnects osciloskop it wont work anymore.

I paused at 3:15, you made a huge mistake there, when you use an oscilloscope to measure line voltage you should never connect the oscilloscope ground lead to anything that is not ground or earth. If you connect the cable in reverse you would short circuit the main power and potentially damage your probe and oscilloscope

@SuperSerNiko97 3 дня назад

I should add that if the power station is only running on solar than it should be floating and shouldn't be an issue but in the last video you had it connected to both main and solar so it's very dangerous

Guess I was lucky...

@InssiAjaton 2 дня назад

In principle there are the ground issue and an inrush issue. I don’t want to speculate more about the grounding than what others have already done, but I’m speculating about inrush. Both the UPS and the data center have likely very high inrush currents in initial charging banks of capacitors, or in the case of the UPS, a battery bank. You can fall a victim of the short, 20 to 50 millisecond, up to 100 A inrush that trips protections, maybe in the UPS. Just a thought - not knowing about the internals of any of your items in the installation.

@MyPlayHouse 5 часов назад

I have thought of this as a possibility,, and it might still be.... and that was why I did the resistant load of the pool heater,, to smoothen it out,, it is just not a good long therms solution. :-/

@The-Weekend-Warrior 3 дня назад

Grounding going into the UPS is not grounding the unit itself as power going out is usually isolated so you would need to find a grounding point on the unit itself or the power cable going INTO the Allpowers...

@MyPlayHouse 4 часа назад

Not sure if this is posable..

@syl764 3 дня назад

What does the UPS log say? It may have been an undervoltage, or an overvoltage. You can change the upper and lower limits the UPS will accept before it starts correcting. You can also turn down the sensitivity of the UPS. My APC UPS will take just about any power at all and provide clean power to the server.

@MyPlayHouse 4 часа назад

Someone else suggested me to look there,, and it(the log) was absolutely useless :-(

@yaronilan2317 3 дня назад

Morten, how do you supply power to your home data center? Are both of your racks connected to a single breaker in your home’s breaker box, or are they connected to multiple breakers? If they’re connected to a single breaker, what is the amperage capacity of that breaker? If you were to turn on all of your servers, would this capacity be sufficient? Can you one day prepare a video on the topic of supplying power to a home data center?

@MyPlayHouse 3 часа назад

One braker,,, did you miss that all of the stuff I am running is only 320W to 460W ??

@kna60 3 дня назад

@ 15:43, Isn't this the UPS's periodic self-test process, which briefly switches to batteries to test their condition and availability before switching back to the mains?

@MyPlayHouse 3 дня назад

It does that onces a week,, It did it the day after I did this video.

@peterjones2411 3 дня назад

I commented in your las ups video about the allpowers giving an isolated output this is still your issue here you took a big risk connecting your oscilloscope like that to your mains as the ground or neutral or minus whatever you call it in Denmark on your oscilloscope is connected to directly to the earth pin on oscilloscope mains input so you could have shorted mains to earth through your oscilloscope and destroyed your scope or at least poped the breaker you only survived it because like I said previously your alpowers is isolated output and since one of your terminals was connected to ground through the scope your ups worked. try powering up ups from scratch without scope connected. " DON'T EVER CONNECT YOUR SCOPE TO ANY MAIN WITHOUT AN ISOLATED PROBE OR BATTERY POWERED SCOPE"

@MyPlayHouse 3 часа назад

Ahh it was not total luck,, well I guess I could have put in the plug upside down,,and that could have been bad...

@netsspam 3 дня назад

i caught the monitor on the first reset, and it appears that the sine wave, right prior to the ups cutting off, appears to be faster before the power cut out, maybe even double the freq, then after resetting the sine wave appears to return to the normal hz,

Morten, I believe the Eaton UPSes we use at work have a sensitivity button that changes what the UPS tolerates. Does your UPS have a setting like this?

Humm I do not know,, would be nice to be able to lower the sensitivity,,, this is a cheap UPS :-/

100W of solar-power. Nice. Yesterday we got a little more at the company i work for: 380kW solar-power from big panel-arrays at the roofs. And additional 100kW from our 5MWh battery-container with 1MW inverter. While this test-run the whole company took about 700kW power 😎

Does the UPS log give no indication as to the problem ,maybe the voltage output is unstable?

@MyPlayHouse 3 дня назад

Interesting,, I did not check..!! I will have a look

@MyPlayHouse 3 дня назад

Had a look,, No usable information :-/

@michaeldullaway746 3 дня назад

Is the wave form monitor youre using not considered a load by the allpower? That could be keeping it's outputs "live" when the ups complains and shuts off the input,then tries to accept it again? That would be my thought?

@MyPlayHouse 3 дня назад

The oscilloscope only uses a few watts,, not enough to be a real load,, and I was powering it from the grid,, as I would not be able to see stuff if the R2500 was powering on and off the AC..

@shephusted2714 3 дня назад

you should do more testing and perhaps read up and test other models to get a system that will work optimally - almost there, i think you want more watts coming in but the power is almost less of an issue than ventilation and humidity control - you may want redundant and slightly overlapping systems #failover

@MyPlayHouse 4 часа назад

Well,, we did get a steep closer :-)

@lukayy235 3 дня назад

Maybe the UPS is too picky about the input power. Can you change the sensitivity in the UPS Software? On my Rack-UPS I can set how "clean" the incoming power has to be to be accepted. Just a suggestion, I hope it works!

@dennisolsson3119 2 дня назад

My thought too. According to the scope the frequency was moving between 49.8 and 50.2. it might go further out sometimes and that triggers the error.

@MyPlayHouse 3 часа назад

Yes very likely,,,
