House,

please what is the fg bond rates now?

A goldfish has no hiding place .

Thanks....will order sharparly

bigrovar:
I use qasa rechargeable. Other than battery failure the fan has been working fine close to a year now. Uses between 4w at lowest speed to 26w at highest speed ( which is on per with electric motor fan) the medium speed at 15w is ideal for normal use.

sometimes if panels are installed such that there is internal stress(surface not level) coupled with sun intensity overtime or no room for expansion cos of solid bolting, they may crack

life707:
I think something went wrong somewhere but Tata panels are solid.
I have two that are still firing now 6yrs + 4months

Very nice....kudos

kiekie1:
Hello pals , it wasnt an easy road to/fro Aba-Ukwa east LGA routes BT tnk God for journey mercies ! Installation pics loading as promised ...

Seems this governor thinks BH are joking?

Ok..thanks. will check for it

efuro:
u've been helpful to almost everyone.
my suggestion is to get dis type of fan. my 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.

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

abunafiu:
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.

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

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

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

tivta:
You should be able to replace the battery

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.

Charge your battery with Nepalight or generator to see if the battery is gone or ur solar system is not well installed.

dicksonadams:
My fangpusun cc do not have display only 3 blue light that blinks, though it has a port for a special cable for reading thorugh dongle on phone or laptop. but i dont have that dongle it is very expensive.


have mercy on me Dmerciful and Dr chris.

Like others have rightly said, it could be ur battery is not getting enough charge or near its end life. Check ur Fangpusun if the daily harvest is around 2400WH....this is what you need to charge ur battery if it was flat.

dicksonadams:
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

When you make up ur mind to buy fangpusun 60...buzz me 08035415969

mctfopt:
Thanks a lot. I'm following this thread like a hawk. Lol. You guys super rock!

The itracer is just a beautiful piece....i love the beauty,looool. Just bought one for myself Will post pics after installation late dec.

RipVanWink:
ep solar data storage/display capacity isnt as robust as morning star, i have used both, and i believe fangpusen is built along the lines of morning star/outback.

the major issue i have against fangpusen is that it is a lil bulky and has an internal cooling fan, hich may fail or stop due to dirt and thus the system may overheat and spoil.

So pls get your facts my brother

Goodmorning

I am even looking for it. my best friend that bought a used one from those telecom guys in warri is still using his after 7yrs . when he told me i was baffled, i later asked another battery guy the best battery around, he mentioned monbat without myself telling him anything about my friend's own

durodee:
Monbat? Never heard of them. Any further info chief?
Modified: I saw this pic online.Any idea of current price?

Heard monbat battery is very good.....long lifespan

durodee:
Which SMF battery has a better reputation among the readily available ones? I am about to change out my battery bank soon and I don't have the luxury of considering Trojan for many reasons.

I mean different types including Li po batteries. they are light weight but pack a lot of punch and last for years. Thats the direction of storage cells

efuro:
@ abunafie

I really admire ur set up. I wish to get to ur level one day. pls sit back and enjoy ur investment.

@ kiekie1
I have been wondering why you have been silent for sometime, don't be discouraged, you have diehard like us wishing you well.

pls let us have d pix of dat 4kw installation.

@ Dmerciful

do you mean Life POD batteries. I really respect that battery.

Robust system you have and with you battery bank capacity you will be able to adhere to max of 30% DOD unlike us killing the batteries we have due to low bank capacities. I always prefer sealed batteries for safety reasons and the nature of my house but they sure arent as rugged or durable as the flooded types....considering migration sha but the cost is scary now
Thanks for sharing....inspired

abunafiu:
As per harvest,
I am fortunate to have a 4kw PV array being controlled by a classic 150 mppt device. My battery bank is 48v 450ah Trojans. My inverter is also a 4kw Mustpower Inverter charger. From lessons learnt from seniors, I had to add 2 MNSPD for extra protection against surges, ligthnenng etc.
I have been living off grid for almost 6 months now.
My harvest has between 10kwh and 16kwh daily.
By 6am my battery voltage is usually not less than 49v except for few instances where I recorded 48.5v.
Even though I recently observed some slacks in 2 of my Trojans (bought June 2014) but the overall performance is still like new. I observed that each time I drain the battery bank below 47V, those 2 batts will drop to 3.8v while others remain at 5.9v. Since I observed this I have always avoided deep discharge though once in a while I have to. But I can comfortable discharge my battery to 47v without any worries. The problem starts when I go deeper than 47v which should be totally avoided.
So I plan to remove the the 2 batteries over time but replacement is not an option for now due to unavailability of the batts nationwide. (interested seller can pm me if you have 2 spare T105 Trojan for sale).
Saipro was kind enough to share a solution to me(not battery repairs) I am yet to implement his ideas but I am sure it's going to work since he uses d same.
Owning the classic mppt was one of the best decision I have taken thanks to Saipro.

For those who think most of us are not sharing enough about our set up, kindly direct specific questions to individuals, others can contribute too.
Fortunately for some of us here we have taken our relationship in this forum beyond nairaland. Nothing stops you from being more diplomatic in asking for help, trust me many will be willing to help.

Yeah but there is massive room for improvement for instance the world is moving towards lithium ion with thousands of cycles at very high DOD, we need to explore that option. i even heard of salt water cell with 10,000 cycles! we need new durable possibilities

GeorgeD1:
dmerciful,
the thread is already active enough as it is. with my seemingly undying passion for solar water heaters you would be forgiven to think it's the next best thing after sliced bread - or maybe it is. but the fact remains that considering the push back from peeps so far, we were once like this when the issue of solar pv was being touted a few years back. many never saw the viability of it all until it's widespread adoption.
that said I think besides a few hobbyists and diyers like me still remaining on the thread, most wouldn't be bothered about posting or replying to anything unless there is something in it for them to gain and probably when they want to sell something to others.

All,

lets keep this thread active....encourage people to go green....save the planet and ur pocket
Post pictures of ur current setup, ur solar harvest, ur power consumption, ur installation.

we can also do reviews of different brands

GeorgeD1

please clarity how a system installed at ground level will supply hot water to lintel level or are you referring to a system that uses a pressure pump?

GeorgeD1:
efuro,

fortunately again, that's not correct. the solar water heater can be installed just about anywhere.
the most important thing is direct and unhindered access to sunlight - much like normal pv modules.
so, what applies to solar pv also applies to it and perhaps to a lesser degree.
there are different variations in installation models. you can even install on the flat ground right in
front of your house. no water tower, no need to mount it on the roof. the possibilities are endless.
as for waiting until you want to set up a new site, again, there is no need for that. solar water heaters
can always be modified to fit into any existing plumbing system. that is what i did. the only thing
that you need to consider is the exact location where you want the water heater to be and then
your plumber will modify your house piping network accordingly.

funny enough, even as a tenant, you can still use solar water heaters. it's really amazing what
the human mind can achieve if only we choose to think outside the box.

break the myth!

Will definitely have something like this when the time comes

GeorgeD1:
efuro,
abunafiu,
dmerciful,
johnkester,
all,

still on my solar water heater calculations, i made a very optimistic assumption in my
calculations about the availability of public power which i thought some keen member would
point out to the house. i had allocated a 12hr average power supply per day in arriving at my
monthly running cost for electric water heaters. now, the question is, what if supply increases
more than 12hrs? then the running cost gets higher. again, what if there's no power at all? then
you are left with no choice than to run your fuel guzzling plant to power your water heater
(that is for those that can afford it) or alternatively you're forced to go cold - no hot water, no joy!
and i dare say that there are countless households where their electric water heaters have
become mere objects of decoration - disused and abandoned all because there is seldom
public power to run them and the 2.5kva or 5kva generators they have just can't cope
with the added load. on the other hand, with solar water heaters, the more the sunshine,
the merrier! and even on cloudy days, you still get hot water because you don't need
the full intensity of sunshine for your vacuum tubes to work.

There is nothing really difficult with inverter installation. basic consideration is that u want the inverter AC input to be connected to mains supply(NEPA) or generator and the inverter output to power specific loads in the house. these specific loads you can separate from the distribution board. You can practice using a small computer UPS and learn from there. You can also watch you-tube videos

haslaw:
Hello house,

I am an electrical engineer with a fair practical knowledge of electrical wires and connections. I am looking for someone I can learn inverter installations from. Something like the practical aspects of inverter installations.

I live in Ikeja, Lagos

You would be lucky if this offer is still available. You dont know the value of what he has put up for sale and like he said if you're buying afresh, u'll spend twice the cost and TBH, he is right. you can always sell that inverter and get a bigger one.

ceelog:
I had considered calling him but the thing is there is no warranty on used products (if anything happens no refund) and the inverter capacity is small for future scale up. As per reading the entire pages...well make I continue sha

hazelj put up his system for sale. it is a good deal and i would recommend you contact him ASAP if others have not already done that.

ceelog:
Greetings all. I just stumbled into this thread while doing some search.
Please Kiekie1, DMerciful, GeorgeD, efuro and other solar enthusiasts can you please simply breakdown what a new solar entrant needs to start his solar story till full scale up.
For instance, I need to start with the following, a 210w plasma (run for 6hrs), a dstv, 2 rechargeable fans 30w each (runnin for 12hrs), 5 energy 18w bulbs (run for 5hrs), phone charging and deep freezer (during the day only).
I can spare 400k and the start scaling up.

Is it feasible?
Are second hand purchases adviceable?
Which are preferred brands for each component even if it means buyin in bits?

Pls I tried to read all 186pages but couldnt.

While not come straight and accuse the Biafrans of supporting Atiku rather that this rigmaraole
