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.
