RE: Testing the ??MPPT ?? CMTP02 Controller UPDATE

RJ, I've always found you right on the 'Money' O$S

RE: Testing the ??MPPT ?? CMTP02 Controller UPDATE

Ok, sorry I started that thread, but the worst part is I never got that MPPT controller ! This is the first time I ever had any trouble w/ shipment, local or overseas. They want to give me a refund, but I told'm I want what I ordered. Now they want me to wait another week before they settle. But it seems like I'll never see anything but the refund. Rich, Your one of my main men. Some call me old moldy. I guess for a reason. Great to save a 'buck' Now RJ, I just looked on Ebay. One seller shows the MPPT 15a like you ordered @ $12.88 another shows $13.86 Please, you might just go after one more. My 20a arrived in 10 days. This happens to be one of the high volume controllers sold. I don't fine anyone saying they have a throw away from this model. I'll try to get out to the shop tomorrow and hook my 20a to a 24/100w panel. Floyd o$S

RE: Testing the ??MPPT ?? CMTP02 Controller UPDATE

Nice to read some of the HiTech Posts. But Hey, I'm the batt boy and not the batter. Hopefully at or near the end of this thread, or the other one running, we will all know 'Exactly what is MPPT?? '(in fact, like science)' If we know the real maybe the fake will also be known?

RE: Oh No ! I bought a Mppt Solar Controller

Looking at the Sec 5 PARAMETERS, this is the way I read it. But then I'm Old and Slow and slower. Input voltage range ~ 12v~20v/ 24v~40v/48v~80v All shown under the 12v/24v/48v rated voltage heading.

RE: Testing the ??MPPT ?? CMTP02 Controller UPDATE

here's the deal for me. I have the ' Technology Comparison' from Morningstar PWM charge control/MPPT charge control ~ "Typically recommended for use in smaller systems where 'boost' benefits are minimal' MPPT ~ 170w or higher to take advantage of 'boost' benefits more. Me thinks the 'go cheapo folks' are correct for less than 170w as per MS. All will no doubt agree that for large arrays the real (whatever that is is) MPPT is the right way to proceed. Added side note; I have the 20a CMTP02 ready to be tested soon.

RE: Oh No ! I bought a Mppt Solar Controller

I have this same CMTP02 to be installed on my e/scooter. The one I'm using has a .1 amp per day draw down on the battery bank. I'm waiting an 30a MPPT @ $49.95 that shows to have a large heat sink on the bottom. Maybe coffee and 'donuts'. I'll work my way up the price range, until I'm satisfied. Here's hoping this CMTP02 has no draw down at night. Someone soon should be able to give us ( a link) to the least costly controller to go with the one panel 120w starter kits. For my part, I didn't need the high priced wire cable @ $2.00 per foot. All I needed was the 24v/100w panel and the right cheapo controller. If making a roof installation, then perhaps the UV protected cable could be helpful in the long run.

RE: Feedback on this solar kit?

Now we are getting somewhere. Any particular panel, or are they all the same? Any particular controller, or are they all the same? What makes them "solar" cables? Sounds like you got a good deal. Thank you, It wasn't as easy as picking brand name stuff and clicking buy but I learned a lot about solar while putting it together. Given time I could do better as even ebay is not Target and I'm working on a quick search with what's listed now. I started at SolarBlvd.com since they have a good rep here. They have a 100w panel for $125 plus $20 shipping to me. 100w panel Add to that a Landstar 10a controller which has been used successfully here for $22.90 (free shipping) 10a controller here is a 40 ft solar cable for $18.99 plus $6 shipping. (will make a pair of 20ft with connectors on panel ends.) Cable That's $192.89 and you still need the short run to the battery with a fuse. I can't find it because I don't know how long you will need it. Preferably as short as possible. There is also this Eco-worthy 100w kit for $209 shipped. 100 kit I have used a Eco-worthy MPPT controller but have no experience with their PWM models. Here is another 100w kit for $202 shipped 100w kit Again I know nothing of the controller Others may suggest other options and I only spent a hour looking so I may be able to find less expensive or suggest better quality. I just wanted to show that there are better options than a HF kit. The last one on the list seems like a good go. For me, I bought like a kid in the candy store. Someone else might say 'bought pigs in a poke. Anyway, the 'big brown' brought his surprise FEDEX their part of three panels. Then there was a really nice Mppt that came from Amazon $ $49.99 plus shipping (now priced at $69.99) Then on to EBay sometimes EBad. China direct. They ship quick but out of the three controllers I bought from them, only one possibly two looked QUALITY. I opened all to take a look see inside. All the meters from EBay seem good buys. Oh well, that was half the fun. It's been said, you never learn a darn thing from OTHERS mistakes. Have fun, look up to the SUN, and maybe even buy the HF Kit. At $129.00 the other day with the 20% off.

RE: Feedback on this solar kit?

Kits, sucker sales and some smart folks who drop in on RV.Net. We decide for our selves at least based on some good info' here. One thing I've found for my self, use lot's of search methods. And for small systems that are not going to be installed on the roof, forget that over priced cables and connectors. . Go the HD or Lowe's, they have stranded wire in all sizes. Don't over do it for systems less that 200/300w I wasted plenty. ~ Let's not add to the "A new fool is born every day"

RE: Feedback on this solar kit?

Building or putting your own Solar system together is half the fun. Solar Kits are more or less, one size fits all. On the controller side. This is a print out from "Morningstar" PWM: Typically recommended for use in smaller systems where "boost benefits are minimal" MPPT: 170w or higher to take advantage of the "boost" benefits more. Well, that is what the folks at "MORNINGSTAR" have to say. I have a 24v/100w panel on my e/scooter and use a 15a PWM china direct @ $16.99 (at the time) and WOW it keeps the batts right up there at around 25.2a even after a two hour ride in the sun. Can't beat that with a $500 controller. That's what I think to be the truth. O$S

RE: Feedback on this solar kit?

Hello, I see Harbor Freight has this kit on sale for $140. Yes, I know it's probably the cheapest cheesiest thing I could probably buy because it's from HF, but it's my first endeavor into solar charging, and of course money is tight, as it is for many of us. It seemed to be a decent wattage for the price but I want to bounce it off you folks. The "voltage regulator" it comes with doesn't look like it's a "charge controller" or is it? I may have to pick up a better solar charge controller so I guess that would be added to the price too if necessary. I have 375 AH of battery on board, but am only looking for supplemental charging. Here's the kit: http://www.harborfreight.com/solar-panel-kit-45-watt-68751.html?utm_medium=email&utm_campaign=3413b&utm_source=1020 Thanks! I was in HF today (tent sale too) and also looked at this kit again. Looks good and at $129 on sale. However, I'm a happy RV.Net camper after going shopping at SolarBlvd for one 24v/120a panel then on to EBay for other panels, controllers and meters. Here is the deal. Recently I bought a HF 400/800w inverter for $19.95 This was my first buy into the inverter world. Well, all the money I've saved shopping at HF the last year, got shot down. The 400w inverter runs @ 50 hz so my fan I tried runs at about half speed. Light blub dim. Was afraid to try the little fridge in the shop. So $20 for the inverter lesson. Hope for those who buy the HF Solar kit they do better. Reports seem okay for the small limited output of their Solar Kit. O$S

RE: Feedback on this solar kit?

RoyB, I'm not a happy camper seeing the numbers you present on re-charge, with the PD9155/55a CC. That's almost earth shaking. Anyway I will play and hopefully have some old man fun with my Shelf of Controllers, digital meter and analog meters and three panels of 24v/50w ~ 24v/100w and 24v/120w's. I am happy with the supply from EBay and SolarBlvd. I do think most of us have seen for a long time the HF kits. Glad I passed by and went to visit Google and here at RV.Net Tech Issues. Best folks on earth. O$S Floyd

RE: Feedback on this solar kit?

I'm trying to get up to speed on solar also but in my opinion based just on internet searches that kit is not money well spent. Buy a 100 watt panel and a cheap controller and play with that. It will be much more useful and you can add to it in the future if you decide to. X2
Old & Slow 08/24/13 07:24am Tech Issues
RE: Feedback on this solar kit?

You can get 100w panel for $125 and a $20 controller. That kit has a lot of do-dads that you do not need or want. 100w $125 Agreed here. I read your reports about SolarBlvd some time ago. Bought their Cynergy Panel and also found these are good honest folks. They shipped quick and the panel output is near max.

RE: Solar again?

RJ is not fishin' today. No troll here either. If it works, no need to fix something. Nice quiet EU1000i along with 200w's Solar seems to work well together. Old saying, 'one hand washes the other'. So much can be learned here on RV.NET Tech Issues. Trial, error and maybe some blue smoke. Glad these threads prodded me toward Solar even this late in life. Me thinks it's fun time in the sun. And it helps make the world more beautiful GREEN. Thanks RJ, O$S Floyd

RE: Turnigy meter question

I also have the same meter. The right side of the meter is the load side (battery) and the left side is the Source (panel) The switch is needed in battery side so as to Disconnect the battery power (Red) for two seconds to reset for data readout. I've read the two reds are tied together in the meter. Hmm lot's of fun I have my Watt Meter just handing below the MPPT controller in the shop connected to my 24v/120w Cynergy Panel and two 12v batts in series. My Watt Meter was mfg for SUN-BORN Energy by Turnigy It's on EBay at $42.95 plus shipping. O$S Floyd

RE: Help with shunt ammeter

I assume the shunt was wired into the negative circuit and the yellow wire was attached to the shunt as shown in the diagram. What I understand from others is the shunt negative circuit on this meter is a little different?

RE: MS TS-60 MPPT Solar Controller Data

I'm interested in data. I would like to see my cheapo controllers proved with proper testing. No way I'm I trying to say high volume panel arrays could use these China cheapo's on my shelf and would be of any value. However, I see large arrays that show single controllers on each panel. Would I like to use the MS TS-60 MPPT if I had the need for one of the 60a class, yes. Where the controller is located on my 24v scooter the larger controllers are not a fit. It's mounted where I can read the meter, just under the 24v/100w panel. So, the small less costly China controllers are doing a great job. As per my batts. In the sun I've extended the run time for the scooter but perhaps I'll burn up the little motor. It may be running to hot. As a side Note. The China cheapo meters are also a real boon for me. O$S Floyd

RE: Help with shunt ammeter

The Black wire goes to the negative side of the shunt and the yellow to the positive side according to your diagram. The red also to the positive side. Call me if you wish. I guess all you fellows don't think O$S knows jack. But when I connected the yellow wire to the shunt (negative) the Meter works as designed. This is a three wire meter. No? I'll sign off on this one.
