Blue everywhere. nice neat job. Kudos.

Hello mates...
Have been following this tread for a while and I guess there are great solar inclined guys here.
Anyways, am a freelance in need of a system that can charge nd up for to 6hours daily. Just my laptop, a bulb, fan, phone... N maybe T.V (Am not a good fan of T.V but I intend using out with my system, it's 24inches.)
I stay in a area effete there's electricity from 2pm till 2pm the next day. Meaning that, on one day, I have at least 20 hours to charge up the system as I won't be needing it.
N from 2pm the next day, there will be no light till the next. I hope someone gets the explanation.
So I need a source of electricity to fill the void


I am not bouyant at the moment but with time I hope to expand the capacity. Thanks

Hello gurus in the house.
Thanks for all the knowledge that has been shared freely in this group. I have really learned alot frm this group.
I went into this renewable energy thing January this year for my business. At the time, didnt hav any single knowledge abt solar energy.
To cut the long story short, met an installer who bought and installed d system 4 me. After learning frm dis group, i discovered dat d system was undersized for my load. The System is already failing at d moment.
So this time i want to spend wisely and get it right.
Here is my current set up.
*SOLAR ARRAY: 2.3kw,
*INVERTER: 2kva 24v sinergy inverter,
*CHARGE CONTROLLER: 60A fangpusun CC and a generic 40A CC.
*BATTERY:2*200ah 12v battery
*TOTAL PEAK LOAD: 1300W(including inverter consumption).
*AVERAGE LOAD: btw 600w to 800w
Am open to suggestions frm the gurus in the house on hw to upgrade the system.

Here are some more info to help with ur advice.
Solar array seems to perform well. Av seen up to 1400w on d fangpusun 60A CC connected to the i.6kw array. The generic CC doesnt display watts, only amps. And av seen up 20A on a gud sunny day. And its connected to a 700w solar array.
Battery is obviously failing and doesnt last long due to d amt of load on it. I dnt even use it in d evening anymore. Once its evening, i switch to my gen.

Wana buy all the upgraded items gradually b4 the end of this year starting with the inverter.
Pls suggest a gud inverter with the following features.(premium inverters are excluded oh. I neva get money reach dat level�)
*Low standby consumption.not more dan 50w
*Over load and short-circuit protection.
*Customizable charging current up to 60A
*Should be able to turnoff inverter charging
*shud hav 3 stage charging
*Shud be between 3.5kva to 5kva 48V
*Gud price point and durable.
*Will prefer non hybrid inverter bt will consider hybrid if its d only option available and d price is gud.

PS: Will my 60A fangpusun CC handle my 2.3kw array if i switch to a 48v system? It currently handles 1.6kw array.
Thanks.

nice,bro try water mark the pics as the original owner.
is ur work and no one should tamper with it

They are welcome -
When they install your system ask them to copy the picture and quality of installation
or
just ask them to explain the components and then you will know if they really installed it - especially the two blue boxes in the centre and the grey box immediately next to it on left

They are not in Nigeria market

Firstly the fangpusun 60A can handle the 2.3kw array conveniently at 48v. Your load however is quite high no wonder you batteries failed prematurely. it will be cheaper to review your load and cut-off excess or get low consumption devices.
For inverter type, i will recommend ipowerplus 5kva or similar architecture type without inbuilt charge controller due to their overall efficiency and lovely design. try to get multiple strings of batteries(12 batteries configured in 4*3) to reduce stress per string for longevity even though I strongly recommend lithium iron phosphate batteries.

finally I want to re-emphasize the need to reduce your load and if not possible ensure your battery bank is adequate

There is nothing wrong with it. It is just that people want to buy a tricycle and expect it to perform like a Ferrari.

They buy a N10,000.00 PWM CC and expect it deliver same performance as a N200,000.00 MPPT CC.

You always get what you paid for or even less than what you paid for.

just like iphone phone battery last longer than tecno phone battery abi?

Hmmmmm my Oga

Except you are running all these loads when there is power from PHCN or Gen then I fear for the installer who said you can run a 2hp AC for a few hours off just ~10kW of lead acid batteries o!

Even with 8 batteries it would be a stretch because you will have other loads still running at thesame time.

With 2kw of panels and 4 12v 200ah batteries you should only be thinking of basic loads and perhaps 30 mins max with the iron or pumping machine - running a 2HP AC should not come into the picture when there is no mains power available except your batteries are in Float and the PV array can keep them in Float with the AC running [will be a tall order for a 2KW array with a 2HP AC]

If your current battery bank is over 3 months old I would not recommend adding a new set to join the old. Even at two months, care needs to be taken to when combining old and new batteries - they have to have very closely matched capacity and state of charge.

I think you need to sit down and evaluate what your power needs really are and this will help guide what manner of upgrades (if any) you need to perform. Except you have a fat budget you should prioritize your loads and only size up for loads that you will run regularly.

so all 4 batteries in my string have different voltages btw 11.54 and 12.23v cumm batt voltage was 47.6v,[super cloudy day] have installed ha02 for over 1month now, bank is abt 3months old. need a method to pinpoint the exact bad batts in the bank, ..who knows?

Good day Sir. You said your batteries are 3 months old? Did you get them brand new? Strange for them to be out of balance so early.

So the way to test a bad battery is under load - because they are already out of whack, you may need to charge them to full individually first (you will need a 12v charger for this). After they are fully charged, bring them back together and discharge (run your loads directly off your inverter to drain the batteries without mains or gen input). Use as large a load as your inverter can safely bear for quickest results.

The weak batteries in your bank will be the ones with the lowest voltage under load - all the batteries will seem to hold up at first then one by one you will see the voltage crash/dip sharply on the ones that are failing/bad.

I am assuming you have access to some sort of voltage tester or meter to check the voltages with since you already knew that one battery was at 11.54v while another was at 12.23v

Any battery that dips below 10v while the others are still at or above 11v you may as well condemn.

Once you have identified your weak batteries, you will need to ascertain what is wrong with them and apply the required treatment - sometimes there may be no salvaging a weak battery and you just have to scrap it.

Malevonent:


so all 4 batteries in my string have different voltages btw 11.54 and 12.23v cumm batt voltage was 47.6v,[super cloudy day] have installed ha02 for over 1month now, bank is abt 3months old. need a method to pinpoint the exact bad batts in the bank, ..who knows?

Check you interconnecting cables and the cable from the battery to the inverter. Are the the same size? Are they the correct size? Are they properly lugged? Are the connections tight? Finally are they of equal length? You will be in shock how something that simple can cause an absurd amount of headache.

Just observed my fangpusun 60a mppt cc, 1500w 48v , instantaneous wattage was 1344w current was 25.1amp, was expecting higher, 1344/48v = 28amps or so, could the losses be due to cabling?, or is this normal

who has clamp meter for sale??...my present unit has started having a reading of 36amps..just lying down in its case , need a new unit asap

Ok will double ch3ck th3 connections..they r all 16mm. Half yard each..my 5kva inverter was displaying 15% load...and had solar input of abt 330w 48v setup ..would the solar input be capable of introducing errors?...

Boss... kudos for taking time to respond..as always.
Was thinking there was a new.improved shorter version of this method ..too much wahala in this method..
Wonder how i can pull it off easily..but an electronic batt analyser from aliexpress.but it isnt reliable..results r not consistent.

Current (Amps) is Watts ÷ Volts.

Your batteries could not be charging at the nominal system voltage - they will need to be at higher voltage potential for current to flow into them.

Assuming a perfectly efficient system with zero conversion losses, given a fixed/known wattage, at higher operating voltages you will see less amps and vice versa.

In your case, the operating voltage between Panels and CC will be higher than the nominal system voltage ditto for between CC and battery hence the current/amps flow will appear lesser than you expected using the nominal voltages as divisor. Yet in reality the quantum of power transferred (watts) has not changed or diminished just that you are using an assumed nominal voltage for your system yet the real operating voltages are higher.

Long and short is I think you are fine, you just need to use the actual system operating voltage for your calculations instead of an assumed nominal system voltage.

OK COOL , PErson no dey sabi finish, want to make sure am not loosing any juice unecessarily
did further calculations, its using the cc voltage to convert, cos my instantenous voltage then was about 52.5v. and thus 1344w/52.5v = 25.6amps. i am beginning to respect this chinese panels, guess where the american panels trump them may be on longevity, sustaining this peak production 10yrs down the line, only time will tell.

@kiekie, how much are those your small batt voltage digital display units?

Kwarrect!!!
