The controller was still under warranty. You should have told us before doing the repairs, the factory would have sent a replacement fan. And we have a few from other controllers we could have sent you.

nice oga Chris. I need not to worry u. the fungpusun is good & my array is pretty small.

kibukila:
Has anyone used this type of battery.I want to replace my battery but do not know if this brand is good.Please advise.

give it a try. great brand fails here in Nigeria due to repackaging.

anything goes here!.

Renewable teammates

please i need your recommendation on a good brand of rechargeable fan to use of inverter. The ones i have be buying fails under 6 months probably they are fake.

One love.

You should be able to replace the battery

Not battery failure....fan failure(sometimes bearing become defective, switching power supply inside fails, stopped rotating...crazy)

Hoping to purchase batteries soon........any advice my people?

Go for Ritar battery

I hope it is not lontor? Cause that is what am currently using though it is just a month old.

No not lontor....cant remember the name. but the replacement OX fan got burnt last night.

Thanks++ Any idea of cost/ 200amp 12v?

Thank God its not lontor. Sorry for the loss but it might be as a result of high voltage.

Chai my solar is suffering me now... Let me explain:


I stop charging my inverter with Nepa for almost a month now and I noticed since a week ago now the battery now run down quick. I might go to work and when I get back the inverter might only last 30 nins or less.


I use just a single 200ah battery and two 80 watt connect in series and 2 130watt connect in series and both now connected in series to my fangpuson cc.


Do charger with only solar destroy a battery?

Dmerciful and other guru please have mercy on me oh

dicksonadams,

charging with solar certainly does not destroy a battery. in actual fact, it enhances
battery health and longevity if done properly and with the correct sized solar array.

when you were still charging your battery bank with public power (phcn) you didn't
notice that your array was not charging your bank properly or was undersized because
public power was available to kick in and take the slack but now that you're totally
off-grid, the weaknesses in your array sizing has been brought to fore.

my advice will be to do a proper sizing of your solar panels. it is obvious that your panels
capacity is too small to charge your battery bank properly. and also your batteries may
have already taken a hit due to successively poor charge/discharge cycles. if that is
the case, you may think of replacing your batteries either now or in the near future
and give yourself peace of mind.

for 200ah battery what would you recommend so that I can charge and use

dicksonadams:
for 200ah battery what would you recommend so that I can charge and use

Simple maths....
Your 12v 200ah battery ~ 2400wh.
Your panels should be able to generate 2400wh in 5hrs or less.
2400wh /5hrs is 480w (assuming a 100% efficient design)
If I were you, my starting PV array for one unit of 12v200ah battery will be 600w. With this you're sure of quality charging in few hours.

You may lplease read up previous pages. I was once a jjc, them chief George and Co inspired me.

Thanks chief! Noted with pleasure!

Your 5hrs daily duration is quite short, here in Agbara i get 8-9hrs of sunshine daily

5hrs duration is pretty much standard hours for estimate and design purpose. What do you think will happen days you don't get 8hrs of sun shine?

@DUNKA

Can you please post the charging parameters (Bulk, Absorb, Float and Equalize voltages) for your Mercury 220AH Tubular Batteries.

I will also appreciate a review of the said batteries now that you have used them for about five months.

Thank you.

Hmmm just registered on 08/12/2016 and you are already up to date

Anyway Bulk to absorb 59.2
Absorb time 2 hours
Float 54
Equalization charge 64
Equalization time 2 hours

Batteries are doing Great no regrets whatsoever. Will do a more comprehensive review when they reach 1year in service

Thank you for sharing your charging parameters. I look forward earnestly to reading your comprehensive review.

Though I just registered, I have been following this incisive thread for more than six months. I have read all 189pages.

Dmerciful and other guru please have mercy on me oh

the bolded should be parallel, not series again, if panels r 24v pls confirm
also, ur panels are 12v panels or 24v?...methinks 12v

your total panel capacity is 420w, which is ok to charge your single battery, only problem might b cos of panel mismatch, i hope your cables are sized correctly, 19amps is ok to charge the battery, am suspecting, ur battery may be on its way to the grave, if after

The panel are connected in parrellel to the mppt charge controller, I use a 6mm cable, before I get 19amps or at worst 16amp steady. Now a days Na 13amp be the max if I am lucky. Wire can be hot from cc to battery close to the cc positive

Hi i have a 3kva mecury inverter and 2 flooded mercury battery 225ah. I want to know the amount of panels i will need to charge it effectively and a suitable charge controller.thanks

u've been helpful to almost everyone.
my suggestion is to get dis type of fan. mine is ugly but does it's job. it 4yrs counting. the ba3 are long gone (9 months to it purchase) and it's of no load to inverter cos it's 35w with 15v DC adaptor.

Ok..thanks. will check for it

I am monitoring with the inbuilt logging software of Midnite Classic 150 Charge Controller. The data is automatically uploaded to Midnite Solar website every five minutes and graphed. Later in the night, I manually extract the data and upload to PVOutput website.
