This is dicey... But if d distance btw array n charge controller is not long and you can get 16mm cables,
then I recommend parallel

samnaija:


The panels 320watts Voc is 45.07v. They are 8 in number. Tnks

Please does anyone have heads up on where I can source a solar water heater?

They all seem out of stock on both Konga and Jumia.

Any pointers would be appreciated

Are the panels on the large size. Because the epsolar states 1600watts for max power. And the 8 in number. Do you suggest I return them for smaller sized panels. Will appreciate need to make a decision.

The bigger the panels the better .
You could get a bigger charge controller of 80A like Fangusun flexmax 80A or Midnite classic of 90A. You could also split the panels... 6 on the itracer and 2 on a 40A EPSOLAR (this I have )

Thanks for the help. Would look into flexmax 80a . Any idea on price range

Kiekie1 pls respond

Happy Sunday Sir! Fangpuson mppt 80a is 170k

an idea popped into my head today.
the feasibility of setting up a smf/agm battery manufacturing plant in nigeria.we have the population, so demand is assured once the product is good. still researching on start up cost and other stuff.i wonder why the rich folk in nigeria hvnt done such long ago.

the automobile industry in nigeria is huge, with chinko batteries crapping out every 1yr or 2. a made in naija battery that cud last 2 to 4yrs would sell fast, then the solar /RE batteries

am open to suggestions/ideas/partnerships etc

Cost of production in Nigeria is crazy due to unavailability of power to run plants and as such you would have to produce you own power which is aboutb35% of production cost. You may need to import some machinery and materials like lead. Competing against China is like trying to eradicate cockroaches

The Chinese government unlike ours encourages their local businesses.
Here you also have to invent from ground up the value chain of your product(s)

After these and many more, if the returns on your investments far out weigh the problems then you can go ahead.

Who is familiar with Axpert inverters here? I have an issue where the AC charger refuses to output anything more than 3.8A (no matter how low the battery is) but once the sun rises and the Panels take over I see currents of up to 23A, when the sun sets and it reverts to utility charging, its 2.6A or less. Is something wrong with the charger circuit? Inverter works pretty fine otherwise.

See the chart below - what it's doing between 12 midnight and 8:55am is a puzzle to me

Nothing is wrong with your inverter bros. Just a 'Settings' problem.

Press 'Enter' for a few seconds till it takes you into the 'Settings menu'.

Navigate to Setting Number 11 - Maximum Utility Charging Current - Set a amperage higher than 5A e.g 40A as you desire

That should fix you.

Also check setting number 01 - Output Source Priority should be set to 'Uti'

and setting number 02 Max Charging Current - u know the rest

Summary

Long press Enter to get into Settings Menu, use the Up and Down arrow keys to navigate, Press Enter on any setting number to enter into 'Settings Edit Mode' In Edit Mode use the Up and Down arrow keys to iterate through various options and Enter to commit any changes then Esc to back out.

Report back to base if your setup is different or you encounter any issues...

Confirm Setting 11: "Maximum utility charging current" is set appropriately.
Confirm Setting 16: "Charger source priority" is set to CSO or SNU.

I'm fully off-grid now, but i remember adjusting those settings whenever i wanted to charge from the grid.

Edit: i see Niyi already addressed you...In addition, don't change Setting 01 to UTI. Doing so, your panels will never charge your batteries unless the grid fails. Set it to SBU or SOL.

Exide battery had a manufacturing plant in Nigeria till the late 1980s when they left.

You better find out why they left before setting up your plant.

I was hoping it was a settings issue and I've gone through the manual from cover to cover. Imagine having power for a whole day and the Inverter is using a tiny fraction of current to apply on batteries at 33% SOC. If not for the sun that came out the following day ...

Good day All,

I have been a silent follower of this great forum for some years now. Please, I need your help in evaluating my installation below before upgrading.
Since about 10 months of adding solar to already installed inverter the highest watts i have seen is 402W; while the highest Amp. is 16A. Though, my batteries are fully charged before getting home daily. I'm not not offgrid. Just being curious why 1,200W panel is not generating upto 50% the of the rated capacity.

- 1.5KVA/24V Luminous Inverter
- 2 x 200AH Luminous Batteries
- 4 x 300w Mono Solar Panels - Parallel - (2 x Sunshine Panels + 2 x Joy Panels) - Installed on the roof South side (no sign of shading or interference because my building is a bit higher than others closeby)
- 40a MPPT CC (Chinco)
- 16mm cable

Attached are the pictures of my panels, CC and output.

Thank you.

Mhen 15A Max Utility Charge Current and you have 4 batteries bros plus your peak solar charge around 23A based on your prior posts.

Looks tight!!!

At least leaving setting number 01 as UTI will allow you put all that 15A into the batteries when there is grid power - if you set it to SBU your house loads and batteries will be sharing whatever solar charge is available.

I was never sure whether those inverters supported simultaneous Grid and Solar charging especially the sizes below 4kva/5kva - this would be your best option if supported change setting number 16 to 'SNU' - please don't make this change if you are not sure the inverter supports simultaneous grid and solar charging as management will not be held responsible o!!!

SNU means inverter charges from both grid and solar simultaneously.

CSO means solar will charge batteries as 1st priority and if no solar then grid/utility will charge.

CUT means grid/utility will charge batteries as 1st priority and if no grid/utility supply then solar will charge.

Yeah I checked, there's no SNU for the 3ka and lower models.

Good or bad?

I would say it just means you would have to make the best of whatever power source is available at any point in time.

The grid would guarantee you 15A into the batteries - solar would be the net of total power generated per time less power consumed by loads and inverter self consumption.

Is it possible to have a 2kva or 3kva hybrid inverter with the SUB/SNU function? Any known brand ?

Good morning house . Wishing you all a nice day ahead ! Remain blessed

The wahala is that you're not even getting the 15A sef... This matter is spiritual baba!

Increase your pv array to max out the 50A solar charger. No need for a new CC at this time.
I suspect you have a 400Ah 48Vdc battery bank.

Hello, I have a friend with 4 Trojan L16 in series on a 4KVA inverter. The inverter has programmable charge current. What current should he set it at to ensure proper battery Charge. Thanks.

It's a 200Ah 48VDC bank (4 x 200AH in series). I'm beginning to worry that overcurrent/overvoltage may have blown something on the AC charger part, cos the solar charger looks fine albeit underperforming. If a capacitor popped i would smell it, right?

Hello my people.

I need advice

I want to change my inverter, whilst also being conscious about price.

I've been offered Microteck 2kva Pure sine wave inverter at a good price, which is 24v and better than my 1000watts china Inverter at home now.

I also intend to add one more panel, to take my system to 3*300watts Mono panel from the 2*300watts

CC remains 40amps Mppt

Like how many amps will drop into the batteries after upgrade? Max presently is 32amps that drops with strong sun.

Thanks my people

Not all capacitor pops would smell . . .
