chairman its been miserable. but as of today 1.7kwh/day was generated. i still pump water and use my fridge. on a good wheather day highest from the system is 4.5kwh/day.

samnaija:
compliments solar gurus and the ogas at the top. this harmattan wheather is really affecting solar harvest. none the less we must forge on to overcome this obstacle..

i use an epsolar itracer series 60a charge controller to charge my 48v 200ah batteries.my solar array is 12* 250 watts 3000watts total. according to epsolar charge manual pv input max is at 3200watts. can i keep adding more panels over this 3200 watts just to beat the bad wheather effect on solar harvest..is it of any benefit. guys pls advice

For a 3KW array, 4.5KWH/day on a good weather day is very poor. This implies an array efficiency of 1.5KWH/KW. You should expect an efficiency of at least 3.5KWH/KW on a sunny day. It is either something is not optimal in your installation or your overnight consumption is very low.

I have a 3.6KW array and I harvest between 11.5 - 13KWH/day this season in Abuja. During the summer months, my harvest is between 14-17.5KWH/day. (http://pvoutput.org/list.jsp?userid=46221)

Something is wrong somewhere! I have 255wX6 panels connected to the same type of your CC and i generated 5kWh/day today. What is the usual voltage reading of your system in the morning? Is it possible that your daily or overnight power consumption is low hence the low yield to replace?
Another possibility is a loose connection somewhere. Do a thourough system inspection pls.

Guys I need 6v batteries. Any good brand, supplier

@samnaija...ur harvest is too poor, i hv 1500w panels with 60amp itracer charging a 24v 440ah tubular battery bank..i got btw 6kw to 7.2kw on normal days...but during this harmattan i get btw 4.5kw and 5,5kw...cleaning the panels helped, my harvest jumped by almost 1kw after cleaning.

are ur panels poly?...n ur cc is mppt?
i suspect ur cables, may be too small..hv seen people using 2.5mm wires to link panels...totally wrong.describe how u connected the panels.
what you shud do to know if ur panels is doing good is multiply total panel wattage by 5hrs of sunlight ie sine i have 1500 x 5hrs = 7500w, u may multiply by 90% tofactor in losses

thanks for your observation. my 48v 200ah batteries do not take me to next morning. so by 9 pm i switch to my smaller system. the main issue with the harvest might be the installation. the installer was a bit confused when i upgraded on panels gradually. from my helpful gurus inhouse i tried explainning 3x4 arrangement. was very adamant wanted to parallel the panels. finally i insisted b4 he obliged. then honestly he confessed never installing an mppt charge controller. well charge controller brngs about 115 volts and on a sunny day when i apply load i get 2400watts from pv. never passed 5kwh/day threshold..

Uncle, if you could afford to buy 3kw of panels which should be at least three quarters of a million; you can afford to spare 20-30k to have a competent person look at your installation and rewire as appropriate.

You are loosing valuable energy, almost 60% of your installed capacity. There are a number of good hands on this thread who can either help you or refer you to someone.

Pls make use of it.

thats why i dey here. if i can get someone to check out the system. help needed..

Good morning,
Your pv arrangements maybe be fine especially when you got 2400W when applying load. You may even get more if more load is applied at peak hours.

I am suspecting one or two of your batteries is/are faulty. You may carry out these tests to isolate faulty batteries.

Check your batteries voltage one by one:

1. immediately your system trips off: Any battery with voltage 10.5v and below MAYBE faulty. .

2. During charging (Absorption stage); Faulty battery will have higher voltage(around 15V and above)

Loose connections can also cause poor harvest.

goodday my people. pls what is your experience on SEC battery products for installation? are they rugged? thanks

samnaija:

I suppose your 3x4 configuration means 3 panels connected in series giving you 4 sets that are paralleled. If so, you are in order as that should be your optimal yield connection.

However, you need to confirm that this was done right since that was the first time the installer was doing that. In addition, the suggestions already made regarding the size of cables used remain valid.

Also ascertain that the distance between the batteries and the CC is not too much and that the size of cable used is commensurate to prevent voltage drop.

Finally, as already suggested, get a professional competent installer to audit the setup and make necessary adjustments.

Cheers

I have 3 panels which go in and out of storage as required; because I at times use an induction cooker, they're out of storage right now (back to 3kW of panels).

My harvest mirrors yours. 3kW currently gives me about 9kWH/day because of partial shading till about 1pm (the shadows have "moved" but will return to their "good" position in summer). The Midnite 150 Classic is a monster!

I am interested in your experience with the INDUCTION COOKER. I am thinking towards acquiring one but I needed someone who had used it to share his experience.

Many thanks for sharing.

I have an induction cooker which I have used for over six years.

Induction cookers are far more energy efficient than hotplates. They also cook faster than hotplates while consuming less energy.

The Induction Cooker does not get hot during use since heat transfer between it and the pot is not by convection. The cooker rather induce metal base of the pot to generate heat. Heat loss is greatly reduced because the heat is generated inside the pot.

The down side of an Induction Cooker is that it does not work with your regular aluminium or steel pots. You require "Induction Pots" to use it. These pots are a bit pricey.

Most consume at least 800W. Swift and even cooking. Saves time. Cooks well. Highly pot selective. Generally won't work with most conventional pots around here as they're mostly aluminium (the steel set of 3 pots I bought a few days to Christmas cost me N21,000 and were an excellent bargain, believe me). Currently use two and have two new ones in store as backup, should I need them in a hurry. That's how much I love them.

Wanna look into bio-digesters too. Them seem good to have though a hassle to maintain.

its advisable that we clean/wash our panels after this dusty period , after cleaning at a site we had about 50% better efficiency

Thanks a bunch for the response.

Any particular brands you care to recommend both for the Induction Cooker and the Pots?

I intend to research the bio-digesters, but in the meantime, can you enlighten me further on the technology?

Dear All,
I recently changed my CC from Etracer 60a to Morningstar Tristar 60a. I had no problem configuring my etracer for remote monitoring from laptop. But this tristar 60amp is giving a lot of challenges for some days to connect to laptop for remote monitoring.

I try connecting using the ethernet port on the CC connected to a wireless router using a RJ-45 cable ( see pictures below) and laptop connected to the router via wireless. Then try to access the tristar web server using http://tsmppt15030496 on my browser. I kept getting Server not found.

I also try using MSview, whenever I launch Msview I see the the CC but can't connect to it (see pictures below) . Please all the Gurus in the house I need your help.

You need a hardware called Ethernet Meterbus to achieve what you desire.

For the pots, they don't really have to be that very expensive types, Induction cookware must be made of a magnetic-based material, such as cast iron or magnetic stainless steel so the trick i use when going shopping for pots or pan for use on my induction cooker is to take along a tiny magnet, any pot that the magnet sticks to works..100%.

The brand is Kavido. It is now over six years since I bought mine so that particular brand might not be available.

Just search for induction cooker in Konga or Jumia.

Don't forget to also buy the pots.

nairababa,
my own experience with the tristar meter connectivity has been anything but pleasant.
i think this is one area morningstar corp needs to improve in their devices. in this day and age
when the drive is towards seamless internet connectivity vis iot (internet of things), its really
disheartening to come across products where you have to jump through hoops just to connect
them to your system. indeed, its no longer enough to make charge controllers that have a
99.8% conversion efficiency, those same controllers should be able to talk to other devices by
the click of a button.

Check YouTube....there will be a way there. Y did you dump your Etracer?
