Shinner2010:
Good evening everyone.
I have issue with him, which was because of the late delivery of iPhone 11 and iPhone x.
Have contact him and explain the reason and when those iPhones will arrive and deliver it.
All this issue arise due to my lack of order follow-up.
Everything is back to normal and will work on it fully
Thanks to everyone for ur concerns.

earthrealm:
Throway that useless CC, its a glorified pwm, masquerading as mppt.

Go find powmr or makeskyblue mppt cc...e no go pass 40k/45k 12v _ 48v 60amps mppt

justcallmenuel:
1.5kva 12v Yohako (wall mount) inverter available, #70000. Call/WhatsApp us on 08168986461

earthrealm:
Try and beat this.
3s2p 280w yingli @ noon
Total 1680w installed capacity...harvest 2035w, it even hit 2045w..but went out b4 i could take a picture.
Next step would be to verfiy this readings with a clamp meter, cos i had about 34.6amps coming in @ 57.6v or so

earthrealm:
Yeah..
Just ensure its same make and model...and same settings across board.
The grand patron of this thread Georged1 posted his setup recently, he has 3 cc abi 4 sef

dapsyra:
Yes, you can connect multiple CC to one battery bank

earthrealm:

In what way my brother?.
Cc is the only limiting factor, for a 12v, you would hv to run multiple cc, if you want to have panel array above 700w and still use 12v inverter

ceaser:
The inverter is a true PSW. And a good one too. If AC power is good, it charges well (20A charger I think). It has a lot of battery, load and output info on the display, but unlike some in its category, there is no way to turn the various displays on the screen off.

Penuelseun:
Bought one this week, no inbuilt charger but psw, rated 600w from a guy in Lagos. Very energy

ceaser:
I actually have one that I have retired. Very good product like that. Used for a year. 12v "BTS" PSW with AC charger with 20% 50% selectable DoD. But it's 750kva so I'm not too sure if it will handle your load. I believe the highest KVA with 12v in that product line up is 1.2kva. Higher KVA come at 24v nominal. It was bought off of Konga. I'll see if I can retrieve the link.

earthrealm:
Yeah i know that...just trying to simplify it for him
300w poly and 300w mono....same brand will have major differences/variation in Vmp.

While 300w of most common brands will have close/similar Vmp.
I hv mixed renogy usa, myhome, sunfit mono panels..no shaking cos their Vmp was quite close

Trippledots:
Electronic service life will reduce, Fire hazards., lower efficiency on some models resulting in significant loss of usable electrical power.

ojeysky:
Rated voltage of this is not too far from my sunfit as well. Though sunfit is rated 30v I get between 31 and 34v

ojeysky:
No it's the attached hybrid, which I have now packaged back waiting for any interested buyer.

Trippledots:
Also add that it generates relatively more heat when used to power inductive loads like motors, fridges, ACs.. Etc

feflo:
200watts poly cost 30k each.
For the fact that an inverter is modified sine wave does not mean it can't power heavy loads, it only means the quality of its output power or wave quality is not purely sinusoidal. This can only be detected by some highly sensitive loads like computers etc. I have used a modified wave inverter to power Air Conditioner.

Many thanks sir

New Inverter to go with my battery.

Anytime and everyday I read this thread... I always get serious headaches.

... I dey look all of una like Einstein's

essegis:
Baba, congratulations on your set up. Its not easy. My post has been modified as I have seen my mistake. No vex.

But you are not my friend anymore oo. Na friends like you make me go use ₦1m buy Victron when Chinco spoil trowey full market. See as Victron full one person wall nitori olorun.

Abeg make I come dey go before them go say my Ijebu spirit don start again oo.

My Oga.

The CC is capped at ~100amps battery output. I have a 48v battery system with max charge voltage set to 52.5volts ergo I can only process about 5,250watts of power through the CC per time despite having a 7.7kw array attached.

Benefit is that I see 80-90amps through the CC before 11am.

To the second part of your question, you have/plan 8,900w mounted for a conventional 48v battery system charging between 56v to 59v, you can only process about 6000w through the CC - at peak power you have to consider that you have ~3kw of panels just sitting outside and cooking in the sun, they are contributing nothing to the house loads. To put it technically correct, such a huge PV array would never operate at the maximum efficiency possible.

Hence, it may make sense to buy a second smaller CC and move some of the array to it. 6kw PV on the MPPT 250v/100A and 3kw PV on say an MPPT 150v/45A seems like a sweet spot. You get max solar juice at all times and the CCs work less.

I sometimes struggle to justify a use case for the Victron MPPT 250v/100A because of the very high price The only reason I have one is that I bought and sold some surplus inventory that came at a 30% discount and then kept a few units for myself

I still have the MorningStar CC for sale at 220K please - brand new MPPT 60A in factory packaging

mcTrinity:
It's a split-cell technology methodology.... Saw that first on Canadian Solar. Kind of makes the panel more efficient.
Flames decided to adopt that too.. That's good

earthrealm:
At higher volts..smaller current flows tru the cable...and vice versa....so sending at higher volts enables you use thinner wire..

Same principle why nepa transmits at high tension/voltage, we have 33,000volts, and higher for the national grid.this way immense amount of power is transmitted at negligible losses at extremely high voltages, which is now gradually stepped down at
or close to consumption areas.
Those giant pylons carry 132,000volts if not higher

Morning star 60amps pwm cc cost 198 dollars, same morning star 60amps mppt cost 600usd.
The Pwm operates at about 60v max.
The Mppt operates at 150v max.
The extra 400usd in cost is basically cos of this flexibilty in max input viltage

For solar calculations, using 3% loss and lower is a preffered optimal design factor than 5%

Timtim8989:
If you are trusted... Imagine you paying commission to hire construction workers.
It is what it is.

mcTrinity:
For 12V system (panels in parallel), the 10mm is the required cable

For 24V system (panels in series), even a 4mm cable can serve. But use 6mm

Both cases are at 5% loss

Cheers

essegis:
See the chart provided. A 10mm wire will carry the amps supply of the panels even if you parallel them with no issues at all.

ClickSis:
Using this size of wire for stated installation is a gross overkill.

You have to provide your system details like nomimal voltage (12V vs 24V), distance of panels from CC, type of CC (PWM vs MPPT) to get a reliable response.

Cheers!
