people keep thinking 12-volts system is cheap. You even require thicker cables which costs more YET e no fit power more appliances.

and Laptops could be power hungry most times especially when used for longer hours.

@mikeayus , are the Solar Panels in series or Parallel ? If in series, maybe you put in parallel, hopefully your charge controller would enter PWM mode.
Or better still, get a super cheap PWM charge controller of about 10,000 naira or therabout and use that pending when you have bigger battery bank and possibly inverter wey sabi work

mikeayus:
oh wow, thanks for your genuine feedback.

Can you please advise me on how best to utilise what I currently have ? i mean what I need to bare in mind to work with the components purchased already? as I dont have budget for a new inverter or additional battery now. Thank you

939w from a possible 950w(2*475w) jinko panels from fouani with 60A powmr mppt cc

@linnov8

Was able to screenshot 938.1w from the the video I made while checking.

Hello guys,

I am a DIY Solar user to be and I have bought the following Items for my setup.

1) 2 550W Jinko Solar Panels (TechLand Solar)
2) 12v 3000w EASun Inverter From a fellow Nairalander
3) 12v 200A Battery Full River From Idyllic Tech.
4) 120A MPPT Charge Controller From Gennex Technologies
Now, I need advise on every other thing I need to get to have my setup up and running (Cables, Change Over, other accessories etc. ).

I would appreciate every tip and learnings from you all. Thanks

The 750k can power his fridge of he goes for modified sine wave Inveter as 3kv of such is around 70k

Mind you, solar gen is not advisable because many of such generator has inflated capacity and when it get spoilt, that's the end

Oh, but it carried it initially. Are u still on a 12v inverter or had to upgrade to 24v? I'm on a 1050va inverter and the rated power is 730w. It powered the chest freezer of 105w initially but later on started showing the short circuit error.

I tried it on a table top fridge of 55w and it's still showing the short circuit error. What inverter size do you thing I can upgrade to, to at least power the 55w fridge?
By carrying it initially, was utility on(NEPA or GEN)? I got a 2kva12v inverter. Minimum u sud be looking out for is a 1.5kva or better still 2kva.
Thanks for the response, btw.

Nteogwuija:
Bosses in the house, please I have an issue. I connected my 105w freezer to my 1050v inverter, and I got a message saying "short circuit, please check wiring". Please, what could be the cause of this?

Other appliances like my TV, laptop, lights work normal. The message only shows when I plug the freezer, and then the inverter would go off. If it were an overload issue, it would have shown the overload warning message. This is where I'm getting confused.

Thanks for all your contributions in advance.

Emmaniche, Gshems, this is controller you refer to.

emmaniche:
Someone is offering it for 140k.

Edrizz:
If fund isn't an issue, I would suggest u get an additional 300watt panel of same rating and do 3s3p, moreso if it's certain that u won't be upgrading in the future, then 6mm cable is sufficient else 10mm will be fine going into the future of adding additional 300watt x 6panels

TechGeek777:
6mm² = 30A recommended
10mm² = 40A recommended

Take this chart and enjoy

My ogas in the house, pls i need ur help? Got a must 5kva 48v hybrid inverter with mppt volt range of 60 to 130vdc and VOC of 145vdc. I have 8 panels of 300w with ffl specs of Vmp 32.7, Voc 39.3, Imp 9.18 and Isc 9.65. What's best way to connect it. Distance from roof to charger is about 15m. Installer recommends 2 strings of 4 panels in series then parallel both strings. Also wud a 6mm solar cable suffice or its too small? Thanks for ur help.

TechGeek777:
2kva SMS Sunmate Inverter has 240vdc as the minimum operating voltage, and your panels are 117v combined, don't you think it could be that reason for poor yield?

guente02:
Started showing code 20 on the display and wouldn't charge the battery.

TechGeek777:
What's capacity of panels connected to it, the VOC of each panel and how many panels did you connect in series?

TechGeek777:
Boss, are you still using your SMS Sunmate Inverter, how's the performance like?

adrusa:
SMK inverters are bad. A friend bought two and the two had problems in months.

guente02:
Hey Guys

I'm planning to set up a solar power system to charge two 24V, 150Ah batteries during 8 hours of sunshine.
I intend to use a 24V hybrid inverter. I tried SMK but it packed up in months.
Can you suggest the specific components I'll need to buy, along with their ratings, to achieve this?

Obnoxious2001:
39.8 * 3 = roughly 120v.
39.8 *2 = 80v roughly.

Running 4s is a waste of one panel to me from experience.
So choose your fate accordingly

Obnoxious2001:
2s4p considering you have just 8

If adding an extra panel is not going to be an issue,
3s3p

IllRatherNotSay:
Used Schneider Conext Inverter/Charger SW4024 230V (4000W) available. What is your offer?

futurenix:
Good evening all
Has anyone encountered the new felicity 10kwh lithium battery switching on normally with battery voltage and percentage displaying but no voltage at the terminals?
Charge controller detects no battery connected.
If yes, pls how did you resolve it

emmaniche:
Boss. I have 1500w pv already. Planning on adding 900w, is it ok I add it to my 60amps mppt cc?
