I noticed you are on a tight budget so you need to manage what you have to survive. You can easily be advice here to go 24v if you haven't purchased the above.

But if the above had been purchased, probably my set up could give a fair hint.

3000w 12v satchet inverter
2s 300w africell pv
Powmr 60a ( max 700w, 80v)
Pv is almost flat on a fence airflow is great.
78ft (26yard Ethernet cable in place of regular cables ).
Battery: 105ah LifePO4

Load mostly in the afternoon: 115w freezer( most important), 50w tv, 10w decoder, 35w fan, etc.

Freezer from 9am to 3 or 4pm.

On cc I do get max of 31a at 478w when sun is blazing.

As freezer goes off by 3pm, battery jumps to 14.1v b4 6pm.

Night: Tv, 1 fan and lightings till say 10pm.
2 fans from 9 or 10pm till morning at a fair speed.

Battery drpped mostly around 13.0 or 13.1v in the morning.

At times tv goes off as sacrifice for freezer in the afternoon when sunlight is just fair.

TRY CHARGE YOUR BATTERY FULLY FIRST AND CAREFULLY DISCHARGE AFTERWARDS. IF You discharge with sense, this 12v of yours will work. But in the long run upgrade to 24v to enable you utilize max your 1400w. But the economy could hinder an upgrade.

N.B Attached pix was today

Pls would love a pic of ow u set ur panels on the fence

walexsos:
hello everyone, I have been following this thread for quite some time and sincerely I appreciate everyone for keeping the thread alive....

pls I have a setup of 48v system of sukam 3.5kva transformer based inverter and 4 pieces of 220ah mercury tubular batteries which I use to run my viewing centre( whenever there is football matches at weekends and midweek matches at night) and gaming shop but it doesn't serve me for 24hrs as it's also connected to my room at home which I use after closing at the shop around 10pm
note.... ( I only use it to power few energy saving lights and ceiling fan at home from 10 pm till the next day)

I used 12pieces of 300w panels which was arranged in 3s 4p with a 60amps felicity cc...I am thinking of adding 4 more panels but I am not sure if the cc can accommodate 4s, 4p, below are the gadget used at the two places

game shop
2 slim PS4
4 slim PS3
2 42 inches 4k smart
4 32 inches led tv
2 AC/DC fan at the game shop is


viewing centre
3 50 inches smart TV
2 62 inches ceiling fan

pls should I add 4 more panels or just upgrade to lithium battery and what capacity of lithium battery can run this loads conveniently and still have enough back up at night if need be

Pls post the VOC of ur charge controller and also of the panels used before u can be adviced correctly on ur panel combination pattern

Penuelseun:
Nope, I now use a 60a Must cc, panels are connected in series

Oh ok. Any reason u chabged to must? Does it have a higher VOC for 12v than the powmr

isangjohnson:
I may not really understand what you mean by "an average hybrids require large panel arrays to power loads and charge at the same time" but I've installed 1.5kw 12v hybrid inverter 150v 80a with 2 pcs of 580w Longi pv and 280ah 12v Lfp battery for someone. He powered his 140w freezer during the day and still get the battery to float before 1pm depending on how deep the battery was discharged at night.
I'm expecting 1kw 12v and 1.5kw 12v high frequency hybrid inverter next month and I'll still test the charging system as well.
The issue you experienced may have caused by the configuration of that charging system by the company.

Whats the model of the hybrids. The inverter i use is connected to 3 300w panels and a 12v220ah tubular battery which rarely gets full unless there's NEPA. Have the same system at 2 other sites and its the same outcome.

Penuelseun:
8am to 6pm daily except in periods of bad weather, changed my panels to 2 435w jinko solar panels and so far their performance has been exceptional

Do u still use the same 60a Powmr SCC? If yes, ow do u overcome the voc of 80 for 12v seeing as ur set up surpasses it if connected in series?

isangjohnson:
Dam5reey and Penuelseun advised you to go for the 24v system because of the set-up list you posted. The advice wasn't necessarily for your stated loads.
2.5kw inverter and 1400w pv were also designated for the 24v system and that was the reason they told you to change the CC from 60a to 80a and continue with the 24v system at once.
If you've not bought those items yet and you intend to reduce the cost as you clearly stated, then go for 2 pcs of 580w Jinko or Longi pv, 1.5kw hybrid inverter and 12v 160ah lfp.
This can comfortably take care of your freezer during the day, few lighting points, tv and energy saving fans at night.

Unless he's getting a high quality hybrid inverter, he's better off having individual components. From my experience, the average hybrids require large panel arrays to power loads and charge at the same time. Use a small array and u wud be dependent on grid for optimal charging unless u add an external charge controller

isangjohnson:
I understood you Boss. I was thinking he could still get better performance for the 12v system he's projecting if he can change the 60a CC to 80a CC and reduce the pv capacity to about 1200w
1.5kva 12v inverter max would have been a better option for him.
From my observation, he's on tide budget.

This is cost effective for him. Hope he wont get swayed by RE sha and be looking for upgrade soon like me seeing as his options limited with 12v.

Buchika:
Please experts in the house help me fine tune this setup.
Can these listed solar items power my load without stress.
The freezer and TV will be on only between 9 am to 5 pm.
The 3 fans will be on all night.
The 6 LED bulbs will be on up to about 10 pm

Load :
140 watts hisense chest freezer
50 watts hisense TV
10 watts Gotv decoder
6 pcs 5watts bulb
3 pcs 30 watts AC/DC fan
3 phone charging point

The setup:

2.5 kW inverter
60a mppt cc
1400 watts solar panel
12 v 210ah lifep04 battery

If i was in ur shoes, I'd just change the inverter/battery to a 24v system. Av a 12v system and av bin having headaches in terms of doing an upgrade.

Dam5reey:
60A CC with 1400w panel on a 12V system is a waste of resources.
with these loads, you need at least a 2000w panel, switch the batteries to 24V 105ah use 80A controller or 48V 50Ah LFP to maintain the 60A controller
Hybrid Inverter would have been a better choice.
My recommendation for this kind of load is 24V 2KW Hybrid with 80A MPPT, 2000watts panel to use during the day also to recharge, 24V, 210Ah LFP to power night loads

Having this same dilemma in terms of external CC and 12v system. The max panels the 60a cc can take is 720-780watts so what happens to the remaining. A 24v wud be a better option to utilize all the panels

Zeestone99 na correct person. He's like family now. He's bin a major help in my small installation journey together with this group. Even questions wey no make sense, he wud still nicely respond to u and even offer u better options/alternative. Gotten a few inverters from him but the single one he helped me get from his colleague that was faulty from source, he took 100% charge of it and ensured it was repaired under warranty same day i sent it and got it back.
Thanks for all u do brother.
Plenty more transactions ur way bro 🙌🙌🙌

Or if you have a wise account, you can buy crypto and sell it at the USD section and receive payment to your wise account. Then if you have the wise card, which is linked to the wise account, you can use it to make your purchases on AliExpress.

That is how I get dollars to purchase stuffs on AliExpress.

Thanks

Mavor:
Guy man, I got scammed 17m last year. Money when I been wan use start China import side business. Since then, one kind paranoia dey worry me when I wan invest money for any project. Make una no vex for here.

Sorry if I sounded harsh to you... Na ur best interest dey all of us here mind. No one wants u getting ripped of ur hard earned money here. Hope u make the right choice in the end.

Trippledots:
Hope they are not lower capacity, relabelled panels.

Check your panels, azimuth angle, elevation angle and shading. These three things must be as close to optimal as possible.

The first line is my biggest fear, was only able to measure the volt which was around 34v but not the current b4 installing.
The roof inclination is almost like 70°, no shading around. I guess I'd just add an extra panel and see if there's any improvement before gking thr external cc way.

1xPOS:
there is no such card as Alipay card.

You can use a domiciliary virtual credit card to pay on AliExpress

Which wud u recommend. Tried chipper but seeing almost 1250/dol

Parser:
why not connect in parallel to get more current. And you haven't told us the current that each of the panel generate. A 37V panel should be able to charge a 12v system. U need to give more details of inverter specs and also the current of the panel. And hope Ur array are facing south or southwest

Combining in parallel defeats the purpose (I'd av to climb the roof again to reconfigure) and requires bigger wires. Using a 6mm wire already
Its a 300w panel with abt 9a of current though max i av gotten is 4.
Already mentioned its a 2kva12v hybrid inverter with mppt volt of 30-400vdc. Just feel it doesnt charge well wit solar which is why I'm considering getting a seperate mppt charger. Plan B is to add another panel and see if there's any change.

Obnoxious2001:
Please this is urgent.

Can a 1.5hp AC (inverter AC) run on a 2.5kva inverter.

Would the inverter be able to even start concerning the surge

U can try it and then give us feedback. Its either it comes on or the inverter trips off from overload(if it has that feature)

Pls need advice. I have 3 300w panels connected in series to my 12v hybrid inverter but i feel it doesn't charge effectively so thinking of getting the powmr 60a mppt to charge my battery better.
Panel's Voc and Vsc are 37 and 32v respectively. Seeing the upper limit of the mppt for 12v as 80v(mppt voc is 160v), can I ignore it and still leave it in series or what's the best panel combination.

Oshomo12:
@Mavor, the truth is, 1.5m can't get you your stop guard. That gaming console alone, the power consumption is worth two of my 219L deep freezer!
You will need to remove that first.

Shebi one oga at the top told him battery capacity he would need for his load and his response was did he see fridge or AC there and that he needs an expert obviously. I don commot hand for hin matter.
I dont know who's trying to form for by insisting he's getting 5kv inverter/10kwh battery in oct, who cares?

Mavor:
F*ck off please!

U sud take ur advice. We aren't ur errand boys here. If we all behaved like u, u think we wud learn or av gotten the assistance we get here. Ppl offered u advice/help yet u keep disregarding/belittling it.. Since u know u need an expert, I hope u can afford him? Pls consult one and leave we novices here alone.
NB: Pls dont tell him to design a system that wud run a 55in tv and ps5 for 16hrs for 800k unless u want to get ur hands burnt.

Trippledots:
To power those loads for 16hrs during the day alone, you would need about 13kwh of stored battery energy.

1m doesn't even scratch the surface, for the stop gap you have in mind.

Adjust your load profile or expectations from what 800k can get for you, to avoid heartbreak.

Lemme help him by breaking it down. He wud need at least 10 tubular batteries or a 10-15kwh lithium battery. Thats over 2.5m and doesnt include inverter or panels. This is just for stop gap as he claims.
Yet he keeps saying he wants a 5kwh lithium/inverter for main set up. Its well with him.

Mavor:
Please read it again and comprehend. I take God beg you!

I can comprehend very well. U sud cut ur coat according to ur clothes and stop taking us for a ride here.

Mavor:
600k for a temp stop gap solution pending when I purchase the 5kw system before Dec. The stop gap solution should be solar recharge, LiFePo4 battery, be able to carry 2 laptops, 1 standing fan, one 55 inch LG smart TV, one PS5 console at least 16 hrs in a day and 6 white energy bulbs security lights switched on at night.

This is obviously a joke, right? All for 600k abi 6m

ayinba1:
Dude, No- That’s why I’m still posting it. I’m quite disgusted with the installer.

Take it to all those battery chargers and ask. I had a similar experience and gave one who fixed it. They av what they mould to it

obitobe:
So you can over panel your system but ensure your connection does not exceed the specified VOC and Rated Amp for the charge controller. I have a 3600w pannel connection on a 60A, 145v Charge controller and my system is a 24v. what i simply did was to respect the charge controller specification and i have been running it for a year now without issues. The only thing is that the charge controller will limit the wattage been generated to the CC specified cap wattage and waste the others inform of heat.

Being curious to know.. while using a 60amp CC with flooded batteries, does it send the whole 60amps into ur batteries while charging? If yes, wont that quickly damage the battery as a result of the high current?

TechGeek777:
Dollar was around 1608 when he posted that figure.

Compared to current rate, you would know why @isangjohnson posted that price point

Okay then, keeping my fingers crossed for his next price list.

Valto:
cheapest tubular is about 340k, highest about 450k
my professionally coupled 12v 105ah 1,344kwh lithium battery with 100A Bluetooth bms is 350k to 400k, with over 10 to 12yrs lifespan.

@techgeek777. That's why i had to ask if it wasnt an error by isangjohnson

HeavenlyBang:
Can connect in series+parallel to meet both voltage and current specifications with minimal power loss.

Yeah, generally 3kva hybrids do better than 1440w, because they're equipped with 80A+ MPPTs. I'm more interested in the niche cases like the SRNE or people who use standalone inverters plus 60A MPPT CCs (Powmr's is capped at 1400W, Felicity's capped at 1650 W).

We still saying the same thing. Whether u connect in series+parallel, the goal is not to exceed the device VOC or u wud be looking for trouble. Some ppl here oversize their panels with their CCs but keep a keen eye on the VOC to avoid stories that touch

HeavenlyBang:
VDC isn't much of an issue, as you can get past that with smart wiring.

SRNE's 3KVA hybrid for example, is capped at 1440W.

The popular Powmr 60A MPPT CC is capped at 1400W, even. How do people go about it?

Lolz, how's VOC not an issue?
Dunno abt the srne so can't argue with you. Its fellow 3kva competitors like felicity, powmr and even sms can take way above 1440watts of panels connected

gifted65:
During the day, it powers our freezer and other appliances which is cool.

Okay then
