You might find that the plug into the TV is a strange one. If you don't want to cannibalize the one from the brick, here is some info for you:
If the batteries are low enough to take all the amps it is putting out, the voltage will rise over time till it hits the target number. That is not uncommon.
Having said that, could there be OEM versions of the PD which don't have the 14.4 stage activated? They might need the pendant to be plugged in? I dunno, just throwing it out there. If it's an aftermarket PD which you installed, I would sure think it is capable and ready to go to 14.4 as soon as it is able to get there.
Buy one already. Set it at 14.8V or 15.0V add wire, mount it out of the elements, close to the batteries, in storage area, and run fat wire, call it good.
Your needs are the same as mine, it works fine. Always connect to the battery first before turning on the PSU.
Thanks. Yes, I am convinced that the Mega Watt would do what I want, albeit with a few amps less than I want. Now I'm wondering if a 45 or 60 amp PM3 Power Max would do the same, only more, once the pot is adjusted. It sounds like it. But I can't get a handle the reliablity issues. Both BFL and J have had issues with their PM units, but in all the threads and posts, I just can't get for sure if it was due to turning up the voltage or what. That's the last remaining question I have as far as what's been discussed in this thread. :)
If I can't get a handle on that, I'll just punt for now, and keep an eye on developments. I don't need to do anything for a couple of months.
We had a Vizio 22" which used 21 watts. It went with the previous MH.
So we bought a Samsung 22" which has a 12v brick. I made a cable to power it direct from 12v outlet. It is very low draw also, but I can't find my notes to give an exact number.
BTW the Vizio did not work well if viewed from below. We had to tilt it to line up with our eyes. I can't recall the Samsung being as bad, but I think it has the same problem to an extent.
No, I am NOT looking for float!
I'm looking for a charger to put in a lot of AH in 2 hours of run time on an Onan genset. Period.
I gots float otherwise covered.
And equalizing too.
I gots confused by you asking so often whether the mod PM3 did float. :)
The tangents make it hard to keep up.
I was trying to make sure I understood what it does and doesn't do. It sounds like it would do what I want: Full amps till full volts reached, then hold the volts while amps taper. Unless it's now unreliable or flaky in some way? I would retain the regular wfco converter for converting, float charging, etc.
My Class C has the converter going through 27.5 feet of #6 wire, then 3' of #2, to get to the batteries. If yours is like that, even the upgraded converter is going to struggle. I can and will relocate or replace mine into a kitchen cabinet under and behind a drawer. From that point it will only be about 5 feet of wire total to the batteries. The existing wires going back to the distribution panel will remain in use, there just won't be a converter back there too.
You might have a similar place to mount a converter. You'd have to run its 120v power cord to an outlet, which in my case is no big deal.
I believe it's on the Discovery channel.
We've watched several episodes. The time they devote to the purging of possessions is interesting.
What bugs me is how they keep using big composting toilets, yet they have sinks and showers. They do not explain the whys and wherefores. Makes me wonder if they are dumping gray water on the ground.
BFL, on the PM3, how did simply adjusting the voltage pot make it hold the full voltage in absorption, and also no longer float? Or do I have that wrong?
I don't know how it does it :) The procedure is to plug it in on bench no load with multimeter in the output. You will see it says 13.6. turn that up to 14.8. put the lid back on. done.
Now when you start the recharge from any SOC , it will bring the battery voltage up to 14.8 (Bulk Stage) and then it stays at 14.8 while amps taper. (Absorption Stage) that's it.
I don't know if it will ever float after a long time at 14.8, since I never leave on that long. I suspect all the voltages will rise when you crank up the pot. On the Paramode, which also has that internal pot, when I cranked that up to 14.8 (from 14.2) it also raised the float voltage from 13.6 to 14something, forget number.
Well that sounds ideal for a fast genset charger. Is there a question about the durability, then?
I have their 50w panels, they work fine. Note, you have to supply cables to their junction box though. The j-box has screws which will accept a round lug, or you can solder to C-shaped tabs. The box has strain relief squeeze connectors.
I just ordered two of the 100's to put on my roof.
Just to make sure I understand... On a PM3 converter, adjusting the voltage pot turns it into the same type of power supply as the Mega Watt, Mean Well, etc.?
First, it outputs full amps, until voltage setting is reached.
Then, it holds that voltage and tapers the amps.
And no float?
It seems crazy that simply adjusting the voltage setting will cancel the voltage step downs in stages 2 & 3. But if so, I'm very interested.
I had a 93 Jayco up until recently. I rebuilt the faucets within the past 5 years. The parts are out there. I can't recall the brand, but they are an RV brand used by OEMs. Search RV faucet parts on google and see if that leads you anywhere.
One of the other members here, I think it was jrnymn7, modded a Boondocker 45. As I read his account of it, it still drops voltage as soon as it hits the target voltage, but the whole curve is higher in voltage. So instead of 14.6 dropping to 13.6, it's say 15.2 dropping to 14.2. BFL, you say your modded PM3-100 just stays at the 14.8? Just by setting the internal pot? Is the internal pot still present on the new models? On all sizes, or just the big guns?
30 AH on a winter day in AZ is possible with 150W, if it stays there all day long. Not 2-3 hours.
Yeah, that's the problem with cheap chargers, they don't see the battery voltage after voltage drop.
I don't know why running inverter at supper time should have any effect on solar. "Supper" is usually something that comes later "dinner", meaning around dusk or later :)...
March 8 of last year at Roosevelt Lake, AZ, I got 54 amp-hours from my 100 watt portable, re-aimed several times during the day. 9+ hour time span. It was a clear day, as you could guess. :)
I am the original early adopter... I bought a Mega Watt for $55. I have one 150 AH battery. That's a hair less than a pair of Group 27s DC's....
NB, can you describe what happens as far as volts and amps over a two hour period? And also if you let it run for longer?
What I'm asking is, does it behave as a constant current charger at first? Sending max amps, while the voltage rises through the 13's, and topping out at 14.8?
Then, does it taper amps while holding 14.8? (Constant voltage)
If left on for 24 hours, would it taper amps down to next to nothing while staying at 14.8v? I don't plan to do that, but I want to understand how it behaves.
The object here is for the optional PS to take over when the P.O.S. OEM converter decides to lean on a shovel, right?
No. I want it to be the initial, bulk charge. Only for those times when I charge from a genset, up to two hours or so. From what I've been reading, it sounded like the p.s. would actually outperform any of the converter chargers for the first two hours of charging. Am I wrong about that?
A Mega will do fine. Set the voltage to 14.8 Two hour of "BOOST" at 14.4 will deliver around 60 to 70 amp hours. When it drops back to "NORMAL" at 13.6 the game is all over. The batteries are going to laugh at that unless you use a sundial as a timer. This is where a power supply kicks in and fills the gap at 14.8 volts.
I'm not sure if you are saying using the Mega for the first two hours, or for two hours beginning after my converter drops to 13.6V. BTW I currently have WFCO, so 13.6 is probably the most it will ever do.
So am I on the wrong track?
So, if using the Mega or Mean 30-40A stuff wastes gasoline, I'm probably tripping over dollar bills to pick up nickels? Like I said above, I thought 40A was about the limit I should throw at the batteries.
BTW, cables will be 3', and fat.
