Cycle Satiator Question

[titusmc]

Anyone know if the Cycle Satiator (24-48V) can run on DC? As in 60-80V DC through the normal AC input? Or will something inside not like it...?

I emailed Grin, but haven't heard back yet (1-2 days since I sent it) so I figured I'd ask here.

I'd like to use it on the output of a DC-DC boost converter connected to a 48V solar array to charge my 14S 52V batteries.

My apologies - I didn't realize there was a main thread. I found it very easily from a google search, but I missed it using the forum search.

Anyway, for anyone who is curious the answer below was given by Justin in the main thread:

It works fine at 90V AC, but from a straight DC bus you need to get up to 120-130V in order to initially turn on the PFC stage, since it has a higher turn-on threshold than operating threshold. So yeah running off solar would require a relatively high voltage solar array.

Question for you since you are doing what others want to do here. ( use a solar panel and boost DC-DC converter to charge their batteries, even if it is only for extended range .

What make and model of Boost converter do you have ?

Cost ?

How long have you used it , to determine quality/service life ?

Any other info about it.

Boost DC-DC converter is also called a Buck Converter ?

Thanks

Boost converter makes higher output voltage than input.

Buck converter produces lower output voltage than input.

Buck-boost converter can make either higher or lower voltage output from input.

Thanks,

when I researched a Boost converter it was nearly or over $ 300 that made the project of a portable 120 watt solar panel too much money , when also adding up the cost of
$ 350 + for the panel, to make the project worth it. A spare battery would be more cost effective, and less to carry around as well.

If there is a much more affordable, quality boost converter that someone has found to work for a long period of time, I would reconsider the portable / range extending solar charger idea a try.

There are numerous small DC-DC boost converters on eBay for under $20. They usually claim 10A max. I have several but I haven't had enough time to truly test their performance or reliability - I've only verified that they can indeed boost my solar panel voltage (12v) to my battery voltage (13S - 54.6V). The ones I got have CC and CV potentiometers for current/voltage adjustment. I'm planning to replace these with digital potentiometers so I can have an Arduino adjust them to do MPPT.

And it's usually to much trouble for moderators to post it...just point it out...
