Help find a solar controller

[hogasm]

I need help finding this solar controller.
My buddy has this installed with 2-100 watt Renogy panels on his Sprinter.
His system has been working great for 2 years so I am looking for this controller.
thanks

I ended up buying my second MPPT solar controller off Amazon, after buying my first, super cheap MPPT solar controller off eBay. There are many, many cheap solar controllers, but I believe many eBay ones are not true MPPT controllers. At least some of the Amazon ones have been analyzed, admittedly by Amazon Reviewers, to be true MPPT.

My cheap one off eBay worked, but I never took the time to see if t was truly MPPT. I just never got close to the solar panel output I expected, so I swapped it out.

No problem.

Also found a little write-up on it...

Singapore DIY Solar: Review of my Taiwan made MPPT Charge controller

I guess it would help if the reviewer really understood the difference between MPPT and PWM controllers. All that said, the thing that I would like to see it have is battery temperature feedback.

Going to their website MPP Solar Inc » PCM2012/3012 Series

you can find a little more information, it is interesting that is actually supports a com port that you can use to alter the charging set points, and other valuable things. I see that as a big plus, although it does not talk about a "program" to do this, I suspect they have one. There is also a review on this site, which is better, but still somewhat lacking in their understanding. I would say my concerns from that review would be that the accuracy of the displayed information. The reviewer says 3 to 5 percent, if you have a separate Battery Monitor this would not be a big concern. It does bring into question the accuracy of the charge set-points, etc

For $160 more than the orig you can get Midnite Solar's The KID for $290 from a few online sources. It has great features and is considered one of the best solar controllers you can buy. Highly accurate, temperature sensing and has diversion load ability with various parameter settings. It also has AGM, and Lithium charge profiles built in which can find tuned for the particulars of your battery bank.

More than double the cost but when protecting a few hundred dollars or more of batteries, I think it is very much worth consideration.

1der you talked me into the Midnight Kid controller.MidNite Kid 30A MPPT Charge Controller Black MNKID Plans are to hook it up to 2 100 watt Renogy Eclipse panels. https://www.renogy.com/renogy-eclips...e-solar-panel/

Use #6 wire from the controller to the batteries...2-group 31 AGM

Not sure about the Wiz Bang Jr. Is it worth installing?

Great! It is a very nice unit with lots of features.

Whiz Bang Jr. is worth it if you want to use the The Kid to monitor your SOC and usages. If you have a different battery monitoring system already, then it is redundant.

Panels: check out the LG NeON line. Thought I saw their single 300w panel for around $300. If you have the space on the roof, more is better.

Wiring: 6 ga will be problematic going into circuit breaker terminals as well as the Kid. If the panels are wired to produce 35 volts, 10 ga wire is sufficient and is the standard for the MC4 connectors. If wired to produce 17.7v then the voltage drop over distance vs wire gauge becomes more critical.

Cool!
