It is sad that we really love taking risks in this country, this is not the first time boat mishaps have been happening in various rivers & dams in Nigeria and the passengers die while some go missing due to negligence of life jackets. Why would school children like this be taken on a boat ride excursion without proper arrangement of life jackets for the pupils?

Pls can you shed more light where this school is? This needs to be tackled to serve as warning to others

Good morning house.. Sorry to bother you guys.. I noticed these ports on my inverter and got me curious what's it's used for.. There also one like this on the charge controller..

RS232 and BMS/RS485

Thanks

You may have to return the Charging Amp of the CC, I asked you to adjust your Inverter Charging Current, Not your Charge Controller.

Just return your CC Current back to 60A because that is dependent on the amount of Solar Energy you have from your Panels.

Thanks a lot chairman.. I also noticed this.. I shall return it to 100% immediately..

Unfortunately, I'm yet to find a way to adjust the charge settings on the inverter.

Pls help me confirm if the other settings on the cc are good.. Bulk, float voltages. Thank you for your immense support

jonescosmos:


Try to reduce the AC charge rate of your inverter to 20A max so that you don't evaporate your distilled water and endanger the batteries further.
Please note that your Charge Amperage is meant to reduce to 0A as your battery charges. Once you hit 0A, it is assumed that your battery is full and no longer taking charge.

Today I explored the 60a mppt charge controller and adjusted some settings.

Brought charging current from 100% (60a) to 34% (20a).

Please check the attached images to see if anything is out of place especially the bulk and float charging voltages.

Bro why are you using 5kva on 2 batteries, you wan kill your batteries be that, and which appliances are you using?

Bro me sef dey reason am say I for get 3.5kva instead.. I got 5kva cos I thought it would give me more room for expansion without worrying about upgrading the inverter.. Only appliances I use it for are fridge (not sure of the fridge's wattage cos my daughter peeled off the sticker but it can't be more than 500w), 1hp polystar ac, 55" TV (not also sure of the wattage cos I can't take it off the wall to check but I'm sure it can't be 200w if at all), 2 standing fans and then some energy saving bulbs.. Note that I don't put on all these appliances at the same time. I've never exceeded 10% load of the inverter capacity.

Press the Enter Button and Hold it.
What brand of inverter is it, do you have the manual?
Rising Voltage and Dropping Amperage during charge is very normal.

Yes, the manual says hold for 10 seconds but I've held all the buttons for 100 seconds and no adjustable options come up. I can only view events but can't edit or adjust any..

I can't seem to find where to reduce the charging current as the [Enter] button on the inverter does not prompt any menu.

The batteries are Quanta Dry Cell..

I noticed the voltage getting higher and the current getting lower from 41A to 40A and now 39A. Perhaps the battery bank is very weak and the inverter is charging it aggressively based on the 3phase charging protocol.. I'll keep monitoring till as much as my fuel can take tonight and tomorrow I will continue.. Note: phcn is not available so it's steady generator so I'm charging it tonight with the generator and I hope this doesn't have a bad effect on the batteries.

You still haven't mentioned whether your setup is On-Grid or Off-Grid.

For the panels, let's use a common logic. If 4 panels could give you 4.25kwh, 6 panels will give (6x4.25)/4 = Approx 6.4kwh.
So with your experience with your setup so far, 6 Panels of daytime energy of 6.4kwh should be able to float your battery of 4.8kw in 5hrs.
REMEMBER THAT YOUR CONNECTION IS 3S2P (3 panels in series in 2 places or strings, then you parallel the 2 strings)

In all fairness to your setup, I must be blunt to inform you that your battery might have been affected by a prolonged undercharging.
Thus the reason for not lasting long enough with a load of 500w.

You will need to charge the batteries with an AC source (Charge till Full SOC), Observe how long it lasts with your 500w load after this, then you can judge the status of the batteries.

Thanks again for all you do. I understand that i have to get 2 more panels and connect all as directed..

I'm currently charging the batteries with AC and I have attached a photo of the charge status.. My question now is the 40A the charging current or is it the current in the battery as shown on the inverter screen? I have observed for a while if the 40A will increase as the battery charges but it's been stagnant, sedomly fluctuating between 40/41A so I guess it's the charging current, which I believe it's quite on the highside

I would love to ask you some questions to be able to suggest further.
The panels you have are not grade A panels so you would be looking at 300KWp per panel, that makes 1200KWp for your 4 panels.
4.25KWh for 5 hours (Average Sun Hours) means you were generating 850W per hour for 5 hours, So you see why I said you should expect a 300w from each of your panels.
Now you have 24V 200A battery bank which is 4.8KW, Your yield of 4.25KW can never be able to fill your battery to float before sun down. Meaning that you are gradually killing your batteries and on the long run, the cells will be weakened.
And I hope there are no loads during the day, because if there are loads, they are also taking power from your 4.25KWh solar energy and battery, making your batteries to get far more less energy to reach floating stage.

My final verdict. Check the direction your panels are facing, check your daytime load consumption, i.e.: get the total load that are powered during the day, your Battery is already about 4.8KW and assuming you have to recharge it everyday after an overnight usage.
Confirm how many hours you have sun at your location.
Get the appropriate panel capacity that can give you the total KW +5% you got from your total daytime load + your battery bank capacity.
Unless your system is connected to the Grid which makes it possible to augment your battery charging via Grid, you are bound to replace the battery at short intervals.

Thanks so much for your detailed analysis.. Bottom line is ; should get 2 more panels? .. Would 2 more panels of 400w or 300w in this case (making 6pcs connected in 2s3p) generate up to 4.8kw or more required to match the battery bank?

Also I noticed my batteries sometimes shows 26v (supposedly charged state) but it would not take a long time before it gets to about 23.5, the inverter alarm kicks off and then shuts down.. Does it mean it's just showing 26v but not charged and therefore not strong enough? My load is always below 10% so I guess the load is below 500watts (since inverter capacity is 5kva)..

I just want to be sure if it's more panels I need or if the battery is misbehaving.. Thanks

jonescosmos:


Oh my God. 3S2P means 3 panels in series, 3 panels in series. And then you parallel the 2 sets of arrays.

Thanks for your clarification and images.. This will go a long way when mounting the 6 panels as this is a completely DIY setup.. I'm most grateful for your inputs and recommendations

mvphenryeto5:


Your batteries are ok, the issue is your panel, are you sure they are of real capacity?

Secondly where is your panel facing?

I'm not sure if the panels are of of real capacity or not.. They're facing west mostly exposed to direct max sunlight from midday till dusk..

mvphenryeto5:


The wattage is not showing?

I guess the wattage is what's showing on the last line of this image.. 4.25kwh. .. ??

jonescosmos:


From the Panel Datasheet you attached your VOC is 46.5V per panel. You have a CC with System voltage of 150V.
A series connection will give you 186V. So you can't do a series connection of the 4 panels.
A system that have a max voltage of 150V will have a starting voltage from around 80V or more.
Doing a 2 series and 2 parallel connection will give you 93V which is not going to optimize your yields.
Thus my recommendation for a 6 panels of 3 in series and 2 parallel which will give you a 139.5V and way above your Starting Voltage.
The implications of this is that your system will start yielding as soon as the sun comes up in the sky.
Otherwise you'll have to wait for intense sun to start yielding.

Please review this response of yours.. You only described 5panels @ the bolded.. What connection (parallel or series) would I use to attach the 6th panel?

I'm considering adding 2 more pcs of 400W panels to it if that's what it would take to have a good charge on a daily basis. So far, I haven't been satiefied with the results. I have 2 12v 200ah Quanta batteries.. I particularly went for quanta at a higher price because I learnt it was better. I'm worried because my neighbor's system stays way longer than mine.. I guess cos I just installed mine and perhaps it's not charged.. Note: Neighbor has 3.5kva 24v setup with 2 12v 200ah felicity battery, while I have 5kva 24v setup with 2 12v 200ah quanta battery. Neighbour's uses 8pcs 200w panels while I use 4pcs 400w panels which I think it's technically same from calculation. I want to max out my options to determine if the batteries are the culprit so that I can return them ASAP.. Thanks everyone

Penuelseun:
2s2p is your best shot

Thanks for your input.. I eventually connected the 4pcs of 400w panels 2s2p and this image attached is the average result I get on a daily (2days monitoring).

Is this good enough or improvement is required to charge 2units of 12v 200ah.. Meanwhile I use a 5kva 24v inverter if that's necessary to know..

All inputs are highly appreciated

jonescosmos:


Just buy 2 more pcs and go on 3S2P connection. Otherwise, 2S2P is your best shot and you can't get the best out of it.

Please clarify your comment and fix typos.. I currently have 4pcs 400w so adding 2 to it would be 6pcs so how it the connection going to be for maximum results? Also, why did you say I can't get the best out of it??

Penuelseun:
system voltage?

5kva 24v inverter
60A 150Vmax charge controller

Good morning house.. Please I need some technical support on how to connect 4 pcs of 400W solar panels to achieve maximum harvest..

Available Apparatus

4 pcs 400w panels (specs attached)
60A mppt charge controller (Vmax 150volts)

I think it has to be parallel/series connection.
This is completely a DIY so any assistance would be highly appreciated.
