This CC is a PWM model, which I want to do a test run on a flooded battery. I also noticed that the CC, on the side, has a USB port, I think it is for charging/power purposes. In the manual I did not see any write up for the USB port, like what kind of amps it provides.
I also noticed in the manual, it has a wiring diagram for the RJ12 communications port. Is there a comm program that is available somewhere for this unit. If the CC works out I might pursue making a cable for the comm port, assuming there is a comm program or the comm parameters that are available.

Thanks bupkis.
For the USB port, I thought it was 5V x 2.1A, but now I am not sure. To bad the Load has to be on in order to use the USB port. I also thought I had a spare RS232-USB cable, but I can not find it anywhere. You would think that Renogy would have those available, on the shelf, or at the very least by special order. There must be a bunch of CC that use the RS232-USB port out there, at some point they might have to be replaced.
The one thing that I noticed on the HP CC, the terminal connector holes are much bigger than the ones on the Rover. Much easier to push in the 10/12AWG wires, and have them connect securely.
So far, this morning, the HP CC is doing a good job charging up my flooded battery.

It is a 30A CC. I gave up on the idea of making the RS232-USB cable, so I hope Renogy makes them available again.

I have used this unit in a different application (DVD changer control) with good success. It is cheap, and maybe it would work for you? Since the pins are all worked out and electronics matched for operation with a PC, then maybe all you would need is a DB-9 female wired to plug into the CC jack?

Thanks mediadogg.
I wish that Renogy, somewhere along the line, would have made an announcement that the RS232-USB cables would no longer be available. I probably would have bought some extras.

If you purchase the materials, I wouldn't mind taking a stab at building it. I could test it with my own CC, with software that you recommend. Of course, the (small) risk is that I fail. If you want to collaborate, send me a PM.

I was thinking the controller had a RJ11, what am I missing? my VS1024 used a RJ45, I simply bought a RJ45 to USB for ~$5 online and talked to the controller.

You are not missing anything except maybe reading my post more carefully. USB to DB9 Male, then (DIY) DB9 female to RJ11. Of course if there is a ready made cable, buy it. I didn't see anybody point him to a solution, so I cobbled up one. I'm sure he would be delighted with a link to the cable he should purchase (and so would I!), so could you please provide one?

Just to clarify, according to the official HP CC diagram, it uses an RJ12, not RJ11. The difference is, one has 8 leads and the other has 6 leads. That might make a difference when you plug in the wrong RJxx. I am still waiting for a response from Renogy, if they will not supply these, then give us a name of a company that does supply them.

Today I did a check for RJ12-USB cable on ebay and amazon, no luck so far. There was one cable that showed the wiring diagram, but of course it did not match what is needed. There were other cables that were listed, but most of them did not show the wiring scheme.
I wonder if Renogy made these cables or were they sourced from China. Interesting that Renogy is so quiet about these cables.

Interesting that Renogy is so quiet about these cables. If you think they came from China, check AliExpress.com, retail arm of Alibaba. You might have to wait a few days, but you can get any and every gadget out there! My rationale for suggesting the other cable, was that the USB to DB9, is a tested, proven design that is known to work with scads of control software for media equipment. The pinout for DB9 RS232 is standard. So, if you know the electrical and software connection to the PC works, and you know absolutely the pinout on the RS232 side, all you need to do is make a simple cable that goes from the DB9 to the exact RJ-12 pins on the CC in the manufacturer documentation. Just hook TX to TX, RX to RX, or whatever. Should be solid, pretty much guaranteed to work. I am so backlogged with fun stuff to do, but I might give this a whirl this weekend. If you don't mind cutting me a little slack and give me the link to the PC software you want to use. I know it is the thread somewhere, but I want make sure I know exactly which one you are focused on, and I might give it a shot - I mean, that is, if it would help you. Oh, I see a couple of links from bupkis ... is that what I should use?

Hang on. Just for grins, I thought I would "Google it." Masses of hits. Including this one: DSD TECH SH-RJ12A USB to RJ12 6P4C Serial Cable with FTDI ChipSeems like exactly what you need, and minimal $13 risk, with Amazon guaranteed return. Took me all of 15 seconds. Trying to support your efforts, but wasting time by taking your word for stuff and finding the exact opposite, is no fun. (Oh, and I went ahead and ordered one - just to have in my toolbox.)
