Thank you for this response. Is it CC? because the CC only has battery selector. Nothing like charging voltage. It is 12/24V60A and 4 24Vpanels connected in series. The inverter is 24V and the two 12V200AH also in series. What am I doing wrong?

4 x 24v panels in series!!!
250w panels?..
Thats risky, as that would be exceeding the Voc of the avg CC, wch i suspect would be 100v for that Your CC...pls confirm this...
In the interim..would suggest you change it to 2s2p asap..

2ndly, wch kind nonsense CC would only have battery selector, there should be a corresponding chart showing the voltages attached to each batt type. Upload a pic of this CC. Am beginning to suspect, it may be a pwm Cc!

Hence the max Voc may even be 50v or 60v.
Send pics showing the spec of the cc & another pic showing the front display.

Thank you for this. I parallel 4 24V panels, the inverter is Also 24V, 2 12v200AH battery in series , the CC is 12/24V60A with only battery selector and LEd indicator for power and charging Mode. Can this configuration caused it?

I think the CC should have a way of programming the parameters. That's where you should make the charging value change.

Then since it's apparent that the CC is PWM, using an inappropriate panel to CC guage wire for very long distances could also impair on the total charging voltage reaching the CC.

2 units 200ah battery; I hope your 4 panels are at least 320 watts each o, for enough daily harvest.

To make things easier, maybe you can upload the pictures of the CC for guys here. You might find someone with experience with the CC.

Has anyone here used this fan I beg?

is a good fan , I've been using 2yrs now

ceaser:


@bolded: As in the 10 watts is consumption at max speed or consumption at minimum speed?

I'm always forgetting to verify that claim. I'll check it out tonight. But my mind tells me the outcome will be +ve.

Please, who has this ATS and a digital timer for sale?? Needed ASAP ...

Hahahahahaha.
Exact same sh,it, i need as well.
Seems we are thinking the same tots.
The device upthere with a timer switch will solve the problem i had been thinking of for months.

I ordered via ali early last month, after asking here and no one stocked it, will see when it arrives

What do you need it for

You will know, If/when you need it as well...

In the words of my mentor Jim Rohn..
When the student is ready, the teacher appears..

The person that invented that device needs 1 bottle of origin served to him daily by a pretty damsel

It's a power source automatic changeover switch. Switches to reserve power if mains power fails and returns automatically to mains when it returns. However, it doesn't have capability to put off the reserve power (generator)

There's a newer version of it that can be placed directly in a distribution box. It's about 6 times 18mm, meaning it takes same ways as 6 single pole MCBs. The newer version has very improved transfer time just like an inverter.

Thank you. Sorry, the 4 panels are in parallel not in series.

Thank you. The distance is 20m from the roof. The panels are 24V275W each. It is a yinglin product. Find the attached picture of the cc below.

Sorry boss. No need for waybill if I had one; we're very close to each other. I only have spare DIN timer switch. Ring me if you need it.

Since your setup is 24V, try re-arranging the panels to 2S2P.

The panel Vmp may be below the threshold that the CC would work. When there's load, the battery voltage is lower that threshold and could be the reason it's able to push in current.

Why don't you use an ac contactor, or two relays like mine(you can use stabilizer relays from electronics stores)

Penuelseun:
Why don't you use an ac contactor, or two relays like mine(you can use stabilizer relays from electronics stores)

1) there are times you want manual operation
2) transfer time is in milliseconds
3) not everyone one know how to connect contactor (energizing input) esp as you need 2NO2NC contactor to achieve both input isolation
4) it has indicator light to know which power source is available.
5) visual feedback. With contactor, you can't tell by mere looking which power source is supplying power.
6) individual preference

Going for the 100A shunt, is it fine?
Battery: 220Ah

Charging current: 15A

Pls you could explain with some calculations so I can learn from that too
Thanks
