Sundry is the original OEM for Sms, welion etc inverters. The newer models with ‘actual’ dual mppt controllers work brilliantly and as you can see, I’ve established communication via solar assistant with it.

Cworth batteries have been incredible, they actually use brand new cells. I established communication using CAN via pylon protocol and so far so good. I have done up to 0.5c on them with no issues.

Cworth panels surprised me, they have been keeping up with the Jinko panels in terms of yield, sometimes even outperforming the jinkos. Believe me, if maybe I didn’t have the raw data, i wouldn’t have believed it’s possible.

Most importantly, #knocks on wood

Sundry or you meant Sunfield ?

Na the same people will still come back to ask which brand is that?

You can't please people!

Which brand is the cell ? lol

Juror:
Did you set the battery voltage in the CC ?
Set it yourself, then also use a multimeter to check the battery voltage directly, don't trust the CC's display voltage, use the multimeter's reading to set your bulk and float on the CC, you can reduce the values by 0.2 too just to give some room.
Check if there's any changes.

Bro, I am using my Pwm Jejely. Besides, I just learnt some few things about the PWM CC.

Just yesterday, I was able to get the highest wattage ever (beating the MPPT) by adjusting some settings on it. I have different battery options (USER 2)and customization options to get a good charging wattage from my panels.

My Temporary Solution
So once my battery is full, I change the settings to a lower options on the WPM to keep the voltage at float even while it’s in use. Another option I try sometimes is when my battery is full via WPM, I rewire it back to my MPPT to keep the battery afloat. Here the MPPt is better because it usually keeps my battery between 13.6 and 14.0 while battery is being used. But the WPM, no matter the float voltage settings, will keep it between 13.3V and 13.4V while being used.


My conclusion, aided by research, is that the new brands of Felicity (without the button) has some factory issues. Just go to google and type “Felicity charge controller error 04”, and check comments under those Facebook and tiktok videos, then you’ll agree with me.

Nice work,
I don't mean to counter or criticize the work done. Just a pointer to the future problems that might arise.

1. THOSE CABLES THAT HAD TO RUN UNDER THE INTERLOCKED PAVES SHOULH HAVE BEEN MARINE GRADED PV CABLES. BEACSUE THE SHIELDS WILL BREAKDOWN DUE TO HUMIDITY AND MIGHT LEAD TO BRIDGING AND SPARKS ON THE LONG RUN.
2. THOSE DIN RAILS IN THE PLASTIC DISTRIBUTION BOXES OUTSIDE SHOULD HAVE BEEN REPLACED WITH OUTDOOR GRADED RAILS, BECAUSE THEY WILL CORODE WITH TIME DUE TO HUMIDITY.
3. THE SCREWS, BOLTS AND NUTS SHOULD BE COPPER OR BRASS COATED TO AVOID COROSION.

One again, Nice job. Kudos.

Thank you. I always welcome constructive criticism. It has been forwarded to the tech team.

I wish people who build houses could give provision to having the house powered by renewable energy and thus make provision for some of these things like output DBs, input source and PV conduit point. Your people had to go through hell to provide this. Good job especially on the wall cracking which was just enough as was needed.

We don't normally do this. It was a massive learning experience for us.

Once in a while. It can go from 700w to 3000w. The higher the wattage the faster it’ll cook.

I usually set it to 2000w and it boils egg in 8mins.

Thanks

My Qasa 300w iron got delivered today, I was sceptical about the weight and efficiency but it turns out to be very effective.

If you are looking for energy efficient dry iron go for qasa.

No sir.

Juror:
Those parameters are just for comms aren't they ?

Mine doesn't really stay on as it goes off and on making difficult use it for cooking and I don't seem to be in the mood to bypass the control 😓😞😔

How will you connect 30 panels to 3 hybrid inverters? Panel are 36v and 14a

5S2P (5 Panels in Series, Then Parallel 2 Strings of that 5 Panels to get 10 Panels) in Three places.

Finally, each 5S2P goes to each Inverter.

Pls guys i got 2 350w Canadian pannels connected via parrarell to 80a powmr pwm cc and 100ah gel battery. My cc receive highest 70w giving highest 5.5a. pls what could be the reason. I called my installer he said I should add more pannels,which I hv paid him to come install more 2 pannels of same 350 Canadian.

Pls guys what exactly can I do. Will Mppt cc solve this issues.? I wanted to get Mppt cc but my installer said the extra to pannels will help the situation. Pls guys I need una input.

Pls guys help a brother oooo

I hv added two more pannels. What I hv now is highest 8a and highest 90w according to the charge controller

I doubt if those panels are original Canadian panels

what are the panels specification, if possible send picture of the back where the spec is.

My problem with that it is 36.25V x 5 = 181.25V which is very close to the 195V max PV voltage. Will it be ok?

Ferdiwar:
No sir.

I think they're just for comms. They can't do anything when connected normally.

If 36.25V is actually the Voc and not Vmp then you should be fine.

Hello house,
Can anyone suggest a good low budget lithium battery with price?

Oh yes, it is ok. In as much as you ain't crossing the 195V max line.

Do the battery have communication between them ?

Yes they do.
