From the attached, connect the +ve cable from the inverter/CC to the +ve terminal of battery 1 and the -ve cable of the inverter/CC to the -ve terminal of battery 2.

Don't mind my drawing ooo 😄 😄 😄

Lol.. Thanks alot. I appreciate.

Ferdiwar:
Share pictures of the dip switches from the 2 batteries.

I'll snap and send when i get back home..

Yes I do and the menus of the ones I've worked on and using is longer than yours reason for my comment.

Jefferyzz:
If you use JK bms u will know that the part I sent are the important part of the settings, others are temperature and some recovery delay settings.

It will help if you also stop being defensive. The group is still a DIY group and learning place for many

brightk:
checkout the meaning of constructive journalism and u will understand my point of view. Did he care to explain the root cause of the issue and proffer solutions to it? SOC drift is not a new thing in the batteey industry. It even happens to professionally coupled packs. His post portrays the view of a bad pack from the seller

Did you use a busbar for the connection?

kristien4:
Please @all, i have a little problem with my battery. They are 2 pieces of 10kwh lifepo4 connected in parallel, when being used, they dont drain uniformly, one battery could be at 87% the other at 95% . Is this normal?

My solar yield this January.

The heat this time of the year caused a significant drop in solar yield. Always to factor in the temperature coefficient when purchasing your solar s so as to have a realistic yield estimate when you factor in the different temperatures we experience throughout the year.

10.2kw sms dual mppt
10.28kw s (12x440w Jinko and 10x500w cworth)
18kwh cworth lifepo4 batteries ( 2x100ah and 1x150ah)
Solar Assistant on Raspberry pi5
Victron smart shunt 300a
Junktek shunt/battery monitor 100a

Achieved 100 percent off-grid status in January.

Take not, load does not factor in the 100wh consumed by the inverter itself (72kwh in 30days)

Peak continuous solar yield this month was 6,500kw i.e 63percent max yield

Peak cumulative load this month was 5.2kw

Max yield - 34.1kwh on Jan 20th
Lowest yield - 12.5kwh on Jan 19th

Max load - 24.3kwh on Jan 27th
Lowest load - 9.8kwh on Jan 19th

Max solar yield in 7days - 205kwh between Jan 17th - 23rd

Average daily energy consumption 20kwh

Something a lot of folks miss when trying to go the renewable energy route is using energy efficient appliances. Converting all appliances to energy efficient ones is as important as getting s and installing batteries. As you can see, most of my appliances are energy efficient.

Energy management is also an important factor, I make use of smart switches which are automated to turn appliances on and off for different set durations.

My biggest energy consuming appliances for the month of January:

1. Lg 1.5hp inverter air conditioner 184kwh
2. Lg 1hp inverter air conditioner 84kwh
3. Starlink and own router 59kwh
4. Double door fridge 52.3kwh
5. Chest deep freezer 34.63kwh
6. Heat-pump clothes dryer 27kwh

Wow, great update.

What's your review about these cworth s?.
I wanted to get one but was skeptical since they're relatively new in the market.

Get Jinko or Longi or original Canadian solar

BigDickProblems:

I’m really seeing this Felicity charge controller as being useless and overhyped. It’s really frustrating.

Did you buy it used or brand new?

My sms 30a has being flawless and firing in all cylinders.

Hv u or anyone here used Kartel s before? Does it come close to jinko and co?

mctfopt:

This is an interesting read.

What are your opinions on the performance of the SMS inverter, Cworth batteries and s. This will help is expanding the choices of others seeking alternatives to the popular brands.

Baba maintain your Jinko or get firman.
Don't experiment with funds of clients unless he is on a budget.

fuckboys:

My sms 30a has being flawless and firing in all cylinders.

Yeah. Brand new in carton. It’s a common thing with the new felicity charge controllers. They return “04” errors even without your battery getting fully charged. Basically, the controller will just stop charging your battery t this point.

YouTube, Facebook, tiktok s are all complaining of the same error issue.

they are not the same capacity. The one showing 95% is smaller in capacity. Try and balance the cells it will help

GloryJoyeux:
Attached is my starlink data consumption in the past 20days.

I guess that is why my starlink consumes a lot of energy monthly.

* that the total load in my previous post does not factor in the load of the inverter itself.

The inverter self consumption is 100w per hr, which translates to 72kwh in Jan.

So actually total load for January is 670kwh.

Cheers

So it is people like you that make starlink vex increase price . What are you doing with 3.7T in a month . Mind is always 700gb lol

Nah, wouldn't even try to use it for any serious ptoject

Did you use a busbar for the connection?

no i didn't, i used bolt/nuts to attach the terminals together.

100% on point.. This jinko just they finish anyhow.. Imagine say market land yesterday, I got 4 pics of 555w. i needed 2 for another client and was told them done sold out.. As in na 3pm the market land yesterday ooo.. 9am today hin done finish.. That why i they kuku find brand way they available jare baba mii....i never see seller of that firman for ib here.. And to buy from that una side go cost me noting less than extra ₦50k for shipment..

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 s surprised me, they have been keeping up with the Jinko s in 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

If you were in Lagos I would've suggested you get Yingli from Xtra Power or even their brand.

I ed jor. I will show you the marking marketing scheme.

But with the way Itel is going enh, they will produce humans o. They are virtually into almost everything now even usb cord.

They make bulbs and power extensions too.

Hello Solar enthusiasts….

This is one of my mini solar system at the farm…. Lately the system does not charge in time like before, the s where cleaned yesterday but still the same

Here is screenshot from my bms

Number of s: 4 X 440w Jinko s
Inverter: PowMr 1.6kva hybrid
