Boss can I get someone to help me do this also? The engineer that install mine had charge me twice.... E. G change wire, new cc but to no avail

If your location is Jos, I can render my services to you for free.

My charge controller has two auxiliary ports which can be configured to switch a relay on/off at preset battery voltages.

I configured the Aux1 to switch on the relay powering the heavy loads DB when battery voltage hits 57.8V and switch off when battery voltage drops to 52.6V. This way, the opportunistic loads cannot drain my batteries even in bad weather.

A programmable timer fires another relay at 4pm and switch the heavy loads DB to PHCN. It also switch the DB back to the inverter at 8am.

Sounds complex. But interesting . Can you pls gives us a break down of the system. Battery size, capacity, numbers and the type flooded,voltage also.
your charge controller type and specs. My guy I am impressed.

Not so complex, but nice way to implement it. I have already modified my parameters to mirror his strategy. Very rewarding results so far! Check his signature for the specs.

My system specs is in my signature as rightly observed by Barezzi.

Thanks for the compliments.

If you say 10-15% when its not raining and with good sunshine, i think its poor. A visual inspection of your setup is a good place to start off trouble-shooting from. I have been pleasantly surprised getting some very handsome harvest all this season. I think the cool weather and dust-free panels are helping. I have seen 4,491W out of my 4,500W total capacity at peak sun intensity (11-1pm ish)

@dapsyra & Chuckdee

Your graphs are lovely. very comprehensive. Midnight solar is great with data display. these statistics are simply amazing. I love data.

GeorgeD1:

babaegun,
you're right.i knew the array size was greater than the capacity of the cc right from time but I wanted to get a practical field test and the monitoring reports have confirmed this. i'll most likely be getting a midnite classic 150.
cheers!

@GeorgeD1

How about your upgrade from Tristar to Midnight Classic 150?

What direction are your panels facing and what is the degree of inclination of the panels?

The above questions are very important and I came to appreciate the importance about 2 months ago. My panels are installed, facing south, which is not a problem. That is actually the appropriate direction. The angle or degree of inclination should be between 6 and 10 degrees. The difference in performance of properly inclined panels and those not so inclined is much more significant than I appreciated before now.

I observed not long ago that the direction from which sun rises had changed significantly to the extent that my panels installed at about 30 - 45 degrees inclination were almost backing the rays as the sun is rising and would remain almost like that for the day. It was then I actually noticed that my angles were wrong. So I dropped the panels to 6 degrees inclination and guess what? My 5.3kw pv arrays which before then would take till about 5.00 to 6.00 pm to fully charge my batteries, can now complete the charge at about between 2 and 3 pm! A difference of about 3 hours! There is a significant improvement in the yield. My batteries now float almost everyday, even when it rains sometime in the day. The beauty of 6 degrees is that whichever direction the sun takes, the panels have complete and direct supply as long as there are no shades!

.....

So you need to do an audit of the system to discover where the problem may be.

Cheers

Please does anyone have a practical approach on how to achieve the 6-10 degrees inclination on a roof that has a higher inclination? I'm planning on setting up panels and I want to get it right from the start...

khanka:
Please, I need your opinion. I use a 1.5 Kva Sukam inverter with two 200Ah batteries. The batteries have gone bad over the past three years and I am in the market for 2 new 200 Ah batteries.
Which brand is the best for sealed batteries?
I am leaning away from flooded batteries because my inverter is within the house and it is not well-ventilated. Thanks for your input.

Hit me up for 200ah quanta batteries. Limited stock available

suretx,
use adjustable legs for your solar rails and confirm angle of inclination using an inclinometer.
you can't go wrong with these two combo...

babaegun,
thanks for asking. that question couldn't have come at a better time as i just received my long awaited
midnite classic. installation was done yesterday and monitoring in progress.
pictures, observations and vote of thanks coming soon...

@house,
Is it typical that when a battery is being charged and reads say 27V, for this to fall abruptly to say 22 or 23V once the source of power is gone?

Also, is it typical to loop two separate solar arrays together and terminate just one cable instead of two for both arrays on the breaker?

I have my thoughts on these but looking for individual experiences on this.

Thanks house.

I want to assume that u are talking about two or more strings( eg, 2*250 watts in series make a string. And you want to connect two of this in parallel and terminate this on a single breaker?) pls don't do that, use a breaker for each string. That's the function of a combiner box, get one or improvised.

Thanks @Oshomo....
So I thought it should be, with DC breakers but I'm seeing some abracadabra.

Others in the house, abeg your kind thoughts.

This would depend on the how deep the battery was discharged before being charged and how long it was charged for before the charger was turned off. Generally though, that battery is pretty much dead. It means it can nolonger hold a charge and hence is best recycled. Never use such battery with new ones.

Also, is it typical to loop two separate solar arrays together and terminate just one cable instead of two for both arrays on the breaker?

It is possible but not recommended nor advisable. slight shading on one panel in one of the array can result in damage or even fire due to excessive current being pumped into the panel because of the bottle neck created by shading. If you have to use 2 arrays especially when their mounted in different locations. Best to use separate breakers and charge controllers.

Does it actually drop as low as 23ish immediately power is gone or is it like 25ish?

If the former, then what bigrovar said is probably the case.

i was almost afraid that u now value your facebook community more than this thread.
Anyway, welcome back.
And I hope we get to see a few of those installation pics too?

The fear of reading the back logs of post kept me away. I now have over 3000 unread posts from my different followed topics.
I had some family challenges around May this year so I missed several posts. I keep postponing the day I'll read all to catch up. It seems I'll have to ignore and continue from here.
