Re: [AFMUG] Is there such a thing as a AC Capacitor?

[Josh Reynolds]

We used these with as many batteries as we needed, figured out a good
charge rate with temp controlled charging (monitors battery temp), and
walked away.

No 24v or 48v or -48v or 12v or 56v to worry about. Drop the batteries in
and inverter and walk away. If you need a gen start they have those too.

Good for very high power if you wanted your plant to have like a 150A
charge rate :P

So what's the advantage of something like this vs an Eltek system. The

Re: [AFMUG] Is there such a thing as a AC Capacitor?

[Josh Reynolds]

Make sure you get the controller kit for them as well, otherwise you won't
be able to program them.

If you need a way to monitor them the battery monitor kit is here:
https://www.amazon.com/Magnum-Energy-Battery-Monitor-ME-BMK/dp/B00DG5SSH8/ref=pd_bxgy_263_img_3?_encoding=UTF8=1=1CX6462ZHMW8QXQQYWQ1

Just make sure it supports the model you are looking at.

High sensitivity often works with generators in my experience as long as
they're the inverter type.

I have about half of our sites converted to DC UPS's. Well, maybe about 
60%. The number one issue I have is putting everything together for it 
is time consuming, but in the end, it's better in every way.

We use Magnum Power pure sine wave on-line UPSs with AGM batts. Yeah we
lose in the conversion, but we also don't have to fumble around with a
couple of various DC voltages.

Love them. Made in the US too.

This is great info. We too have experienced this same issue with AF24's.
Like Gino, we always set it to Low Sensitivity. This setting allows us to
easily run the site off portable generator in a pinch. High Sensitivity
won't allow for a portable genset.

Our issues is exclusively with AF24’s and APC SU750’s.  On a Switching event 
the AF24 lock up about 50% of the time.  We have been changing the APC750 with 
the newer APC SUA750 and the problem vanishes…  believe me we have trie

I don't think it really applies to the intent, but now that I thunk about
it, a friend of mine owns a few gins. A single gin has a bunches of 3 phase
large motors. As a result, he had some kind of load shunting system. He
didn't know enough about it to explain it but it sounded like huge caps
designed to even or the huge start demand  the motors. I never actually saw
the piece of equipment.  His electric bill usually runs in the $40k range
in cotton season for each gin.

Even on the cheapest BackUPS, anything with a decent power supply is 
going to have capacitors with its own holdup time that's greater than 
any line interactive UPS. I've got some old late 90's vintage BackUPS 
units back when they were made out of metal still going strong.


If the power supply is a linear wall wart though, that could be a problem.

The incident I'm recalling was the type where the flywheel, generator, 
and engine are linear on the same shaft. While the power is on it's a 
motor that maintains the flywheel. If the power goes out it becomes a 
generator just barely long enough for the engine to start. The fatal 
flaw IMO is that type can't cold start on the diesel engine. It needed 
batteries to "jumpstart" the flywheel, so you end up having the 
expensive flywheel system *and* a battery plant to cover all your bases.
