If I understand it, the Victron units also have screws underneath but still are filled with potting. The potting allows one to place these outdoors in high humidity and condensing conditions. The potting also has the effect of keeping one from repairing the unit when/if a, or a few, components go bad, or at least making it an arduous task. Since I plan to use it indoors, reparability is a concern for the long haul.
You might lookup HQST MPPT controllers because I'm pretty sure these are actually their units. I've been using one of their 60 amp version and it's basically identical in design. I have mine setup on a 24v bank and it works great. Worth noting, the HQST clone of this controller looks to be about $40 less than the Redodo version currently.
Seems like they missed a trivial and useful feature. Why are they not using the temperature sensor on the LiFePO4 profile to prohibit charging in freezing temperatures?
It would have been useful if the temperature probe allowed for a low temp cutoff.. The batteries I am using don't have this feature.. But I live in Florida, so chances are it won't be much of an issue anyway..

my problem with all these products is i like to take them apart so i can see inside and how there building these things lol i wish i could afford to buy tones of these things to test out and see whats the differnecce are if there is any
It states max PV wattage because of the fact that it's a 40A controller. In a 12v configuration you can get a max charge of 40 amps to the batteries with 600 watts of solar. In a 24v battery configuration you can get a max of 40 amps with 1200 watts of solar. 12.8v * 40A = 512w and 25.6v * 40A = 1024w. It's assumed you would want to over panel with 600w/1200w respectively. The 100V is the max that the charge controller can handle from the solar panels when connected in series. I hope this rambling makes sense. Thanks for the comment.
@@OffGridBasement I understand max VOC in series, however I run 60a Make Sky Blue controllers and maximum PV open circuit voltage goes as follows: 12v battery/80v, 24v battery/105v, 36v battery/160v, and 48v battery/160v. And in bold letters it says not to exceed the max VOC listed for each. At 12v I get around this with series parallel for 74.2v and over-panel the listed 720w with 940w for each controller and string. Speaking of that, Make Sky Blue 60a 119 series is the best bang for your buck in MPPT charge controllers. 🙂
@@OffGridBasement there's a knock off PowMr controller that's about $20 cheaper but has a low quality fan and the earlier 112 series software. They didn't get good until the 117 and 119 series.
I know it sounds funny, but here is what they sent me on the pronunciation. Oh, the actual pronunciation of Redodo is Red-odio, you may get the correct pronunciation from this video, ua-cam.com/video/kSeAn2uVD8E/v-deo.html, hope this will be useful to you. Thanks for the comment.
Wow, my Renogy 20a mppt looks like a toy compared to the size of that one. Are the 40A normally that large or is it because of the Bluetooth that it needs more space?
@Off Grid Basement Great, can you make a statement regarding HF interference in the radio. I am an amateur radio operator and am looking for a solar charge controller that does not cause interference in radio operation. Most charge controllers are very annoying. Many greetings from Germany
@@OffGridBasement The distance from the charge controller to the radio devices is approx. 50-60cm. These charge controllers cause interference from 1.8 - 28Mhz. Even larger distances of up to 3m are not successful. Even attempts with folding ferrites bring little improvement.
They appear to have rebranded the case. The unit is otherwise visually identical to the HQST 40A. I connected to my HQST 60A with the Redodo app and it went right in as it's essentially ChargePro. I imagine the same will work in reverse. It's a good SCC in any case. There's a small review on my channel if you'd like to compare the devices. ua-cam.com/video/-Bg9LLFZ6A0/v-deo.html
The Red Odo charge controller is amazingly accurate. It would be a good choice. That was a great review. Thank you.

Just got mine yesterday was watching your video have to say it’s really cool 👍
I'm glad you like it! I'm sure it will work great for you. Thanks for the comment.
Nice review.
Glad you enjoyed it. Thanks for the comment.
Just ordered 1 last night. Gol dang prime days ..
That's great! I hope it works out for you.

Thanks for the info? Do they have Bluetooth connectivity as well?
@@OffGridBasement yeah they do, these units also allow you to daisy chain another controller using that port on the bottom. RJ11 I think it is
The oem manufacturer is Helios
Redodo/hsq are the importer/marketer all there apps should work
i like this one i might have to get this next time i buy a controller for sure unless they came out with something better by then
Seems like they missed a trivial and useful feature. Why are they not using the temperature sensor on the LiFePO4 profile to prohibit charging in freezing temperatures?
I've noticed it like that for my renogy rover as well. Temp sensor on compensates. Doesn't monitor for under temp protection. Thanks for the comment.
The HSQ version does I suspect this might as well
It would have been useful if the temperature probe allowed for a low temp cutoff.. The batteries I am using don't have this feature.. But I live in Florida, so chances are it won't be much of an issue anyway..
That's true. I find it odd that Redodo is a lifepo4 battery company but their temp probe is made for lead acid batteries. Thanks for the comment.
Another Helios rebrand. Great value
It is a good price. I think the Helios has the option for low temp charging protection but I'm not positive. Thanks for the comment.
@@OffGridBasement All the Helios variants have low temp cutout, that comes with probe. You must have missed that in the box
The load current is 20A, but how much is the voltage for the load?
The max solar voltage is 100v.
Can you check if this has low temp cutoff/protection if you watch Hobotech review of the HSQ charge controller he shows how to enable it
I checked it and it doesn't work. Bummer. Thanks for the question and comment.
Question: are these potted and un-openable or can they be opened for repair?
There are screws on the back with the heat sink. It looks like you can take the heat sink off to get to the internals.
I don,t see this product on Redodo,s site. I was curious on current price, compared to othe re brand companies.

What is the max solar voltage input
It's 100v max solar input. Thanks for the question and comment.

It says max PV wattage is 600w/1200w for 12v/24v, so i doubt that the max VOC is 100v for both. It's probably 50v for 12v and 100v for 24v.

The name is RedOdo, though - you were saying "redOdeeo". Kind of sounded like a rodeo. 😂 😉

It's not the bluetooth. A bluetooth module is about 20x30x5mm.
My 50A victron is smaller. I personally think it is just a design choice. Thanks for the comment.
You should look at the 60 amp model
Likely the physical size due to conversion effiancy of 98 percent.

I've never thought about testing the HF interference. From what distance does the CC interfere with radio operation?
@@OffGridBasement The distance from the charge controller to the radio devices is approx. 50-60cm. These charge controllers cause interference from 1.8 - 28Mhz. Even larger distances of up to 3m are not successful. Even attempts with folding ferrites bring little improvement.
HQST is $40 cheaper on Amazon and it's the exact same controller, only black.
Thanks for sharing and the comment.

cool video i love this channel
Glad you enjoy it! Thanks Jimmy!
What is the max voltage of solar panels ?
100v max solar input.
