why is the time so slow?

Darey00:
Lol, this controller na glorified pwm (my experience sha). Imagine make you get 1.1kw of panels yet controller dey insist on taking in only 200w max. It got so frustrating I had to even increase charging voltage to 15.3v, just to cross up to 300w. Battery never charges.

For your issue you might try downloading the app and control from there, I've made the APK shareable here : https://drive.google.com/file/d/1r00WuSTO3dgmt_y21eJyBbYILtSbLVTP/view?usp=drivesdk

Obnoxious2001:
Please who has experience with this controller?

How do you set up the controller to charge lifepo4 battery (I want to know of I did something wrong).

Now in the image below, you can see the battery voltage is 53v but the controller is still stuck at 12v and it keep giving me 12v parameters which I have no business with.

I replaced the battery with a dry cell and connected it to it to see if it will recognise it, it worked.

Also some of the errors it keeps displaying are not in the manuals

I am currently in Canada, I will buy and ship your cars to Nigeria.
Before we proceed I will verify ID with you

Idk about Thermocool but I have a 198L Hisense that draws just 110w and performs excellently so far, touch wood.

I have disconnected 2 panels, now I have 2pcs for 420 Cworth panels I’m not making use of.

This Cworth panels are very good, even with just 2 panels I get around 700+ watts which is enough for me.

Darey00:
Hi, I use your exact inverter too and the two occasions I've had the MCB Trip issue was an unusual power surge (from Nepa) so the inverter trips to protect itself. If I raise the trip at the back up it works after the current stabilizes.

I think your charge controller might be the issue too, I use an 80A mppt that can take 1040w but I have a 1185w PV array.. a little close to the specs.

If you check the trip at the back and is down u can try raising up if it will come up

Darey00:
I'm interested in this Powmr 60A mppt discussion and I don't think I understand the technical terms given in the suggestions.

I also have a 12v, 2 * 300w panels and plan to add

like 500-600w with an mppt controller based on advice I got here.

The only thing stopping me from getting it on jumia is that 720w for 12v systems.

Please if you say 2s2p kindly break it down for some of us who are technically-challenged. That way I can guide my installer on how to go about it.

Thanks

Please clear me as I want to learn more. 12v set up on powmr allowed max of 80v and 48v set up allowed max of 160v.
Are you saying you can subject your cc to 160v on a 12v battery configuration because it's within parameters?
Am just confused....
Attached was my cc before I changed to SMS Hybrid

I got lifepo4 batteries from used EV vehicles ( not based in Nigeria though). For the hly 26650 5mah batteries. I got them online directly from manufacturer online. Each batteries cost about 8k naira. For the used lifepo4 batteries I used each cell is about 15usd

officialfestus:
Who's in need of this CC?

dollarnaira:
A reasonable panel with a good mppt will surely shoot above 20a. However, confirm your max voltage at 12v on ur cc first. Is the 150v max at 12v ?

amicdan:
Hi House,

Happy New Year.

Please I need help with adding a single panel to a current setup.

Purpose of addition is to increase charge Amps, so battery can be fully charged before 12 PM and load usage during sunlight.

Current setup ( 12 volts system ) : 2 x 335 watt panel connected in parallel with Voc of 46 volt and 40 amps mppt charge controller with max voltage of 150v delivering around 20 amps.

Battery is 12v 172 amps Lifepo4

What size of single panel should be added and what panel connection is required for optimal performance?

Thanks.

Guys i need help


I just recently installed my solar
5kw battery
5kva inverter
100A solar charge controller
9 panels 450w

The battery charges full in the morning before 11-12 but after then, it stops charging until the next day

Why is this?
How can i solve

Dam5reey1:
Its about wrong panel sizing.

You are using the wrong panels on the PWM..
PWM is designed to have panel close to the battery voltage.
On a 12V system
You should use a panel with VMP of 18V max. Not a 335w panel.

If you use Panel with 18V VMP, the PWM will out shine the Toy MPPT.

BigDickProblems:
Honestly, it’s quite annoying. Yeah I will get the MPPT. Thanks!

dollarnaira:
Does it come with manual?
Snap.

dollarnaira:
40a for 125k omo this one loud o.

Ithream:
Sorry, I haven’t used it.
How much did you get it? And what is the Amp rating?
