How is it related here! Do these boxes have inbuilt solar cells & battery? I beg this place is renewable forum not junk room.

Obimind1:
Pls gurus in the house, ur advice is urgently needed. I noticed that my mppt cc 60ah ep solar keeps charging even when there is no sun. I feel something is wrong somewhere but can't exactly tell what could be the problem.

it happens on few occasions
don't worry!

I use fangpusun 60A MPPT I got from Oga Chris.'

initially I love it and kept wondering it is so powerful that it tracks energy from the moon and stars
@10w at 0.4 - 0.5 amps and 1-2AH over night.

but now I feel it is not worth it so I let my mppt sleeps even when "it feels" it still want to work at night.

fangpusun 60A MPPT has a program restart solutions at various point to solve this situation and put it to sleep.

if your CC has program re-set, run it in order to sweep or track MPP (in this case it will find non and sleep) OR
if you have a DC breaker in-btw you PV & CC trigger it off and later on.

worst put off / on the DC breaker btw the battery and CC | am double sure this will reboot ur CC to cancel the problem.

However I feel leaving ur CC on will not damage it unless someone has a different view-point

My regards!

Good Morning Folks,

I hope my message meets you well. Please if you paid someone else to install your solar power for you, don't ask me for advice on fixing it. We charge a fee to diagnose problems on bad installations.

If you are a DIY'er I am very happy to answer questions and offer advice.

There is a clear difference between the two. I do solar for a living and if you are willing to patrnonize someone other than me it is your right. However if you want a performance problem diagnosed it is a minimum of N7500. And if it is an unusually bad job that fee is double

am happy you did not slam the door of experience on everyone.
In fact you are truly a doctor of solar.
doctors admit, treat and get paid

bad installations always tarnish image of solar addicts and lead to lower adherents.

your decision is splendid !!!

bros no be me and flooded again oh

Na wa oooo
Wen those of us with SLA batteries see you people with flooded batteries as big boys (which you are).

No wonder LifePo batteries is gaining favour

abunafiu:
For over a week now.
Ilorin sun has been smiling at me. My daily harvest is now 14 to 15.5kwh daily with my 4kw @250w poly panels.
2 weeks ago, I will shout if I hit 12kwh. I almost felt my panels are going down.

Saipro how far ur side?

Finally ve united my Trojans. Back to 48v set up now.
So I now discharge gently.
Since I am 100% off grid. Saving for additional 1kw to hit 5kw PV strength.
After then start saving for battery replacement.
Not sure if I would love to have a repeated flooded experience.
What about you?

Am happi ur system has bounced back. It seem our solar community is having good tidings from north to south.

My regards to all.

kiekie1:
Yes I know BT for areas with high humidity , dehumidifier is available for purchase .. They work real good as I use 1 in my room. I don't run AC always as I save more with Chillers (Dehumidifier optional)

https://www.amazon.com/gp/aw/d/B013IJPTFK/ref=mp_s_a_1_1?ie=UTF8&qid=1488187874&sr=1-1&pi=AC_SX236_SY340_FMwebp_QL65

Nice work Oga Kiekie1

thanks for the update on Oga Chris observation
and bigger thanks to naira that has just woken up from almost a year in Coma & heavily sedated by CBN

you'll hear from me @ appropriate time even if it means selling one of my split AC
going green is a commitment and do-able affair.

kiekie1:
You are free to always explore as chillers are cheaper than inverter compressor 1hp Aircons.. I have used Scanfrost chillers(170w max consumption & uses 20-30L water reservoir for chilling) in most of my installations and they have been working real good & Scanfrost also provides good customer service ...

Contact me for company price/discounts !!

Nice! 170w max is green better than 900w compresior system.
I hope the price is friendly green?

dapsyra:
Harvest is good

15.9KWH today

15.5KWH yesterday

http://pvoutput.org/list.jsp?userid=46221

hummmmmmmmmmmm

am speechless!

NEPA will really hate you !

and may soon bribe you with 'Ghana Must Come' bags to stop opening peoples eye to free sun energy.

imagine, see your 15.9 KwH x Nepa rate = (thousands of naira/day) x months or (years of going green) - (initial expenses)=

nice one & good savings!

me i still dey 3.4KWH/day Sha!

Hello Gurus in the house,

Please advise

Current System Configuration:
6 x 250W; 3 x 2 Series-Parallel Configuration; Vmp=30.1, Imp=8.31, Isc=8.71, Voc=36.4
CC: TS-MPPT-60; 3.5KVa 48V Inverter

Proposed new panel specification:
6 x 260W; Vmp=31.4, Imp=8.37, Isc=8.94, Voc=38.4

Proposed System Configuration (1):
3 x 4 Series-Parallel Configuration
My concern from varied online source is that old panel would negatively impact new panels and mppt would have a hard time identifying Vmp

Proposed System Configuration (2):
3 x 3 Series-Parallel Configuration; I eliminate 2 old panels and connect remaining 4 in series and parallel to new panels (3x2)
I suppose new panels would give maximum power but old panels (1000W) would be pulled down to a max of (780W) I guess.

What do you think the impact on system would be? Please advise.

Thanks

you did not specify if panels are mixed that is poly mixed with mono.

i assume you are using poly panels

please go with config 1. with ur MPPT

ur CC will probably pick the lowest values (i.e. Vmp=30.1, Imp=8.31, Isc=8.71, Voc=36.4 instead of Vmp=31.4, Imp=8.37, Isc=8.94, Voc=38.4)
at that rate you are granted of harvesting steady wattage for longer time particularly during raining season.
@48V battery bank you need all the panels.

nice effort too.

kiekie1:
Hello 30a a series mppt @ 60-65k , 40a is 70-75k , MT50 black remote meter @ 15-20k .. Thanks

Oga Kiekie1

I appreciate u and ur fast delivery as usual!

I always thought I was consuming more until I received & installed the watt mater.


thanks!

chikkaobi:
Here is the picture of the CC working. Couldn't get the load A, because my inverter is connected directly to the battery.
Though I watched some video on youtube which stat that the CC is just a rip-off, because it doesn't have an Inductor, and would waste energy.
Any Idea the effect it might have on the battery?
If it isn't good, I will be ok if you could suggest a CC.

Are u using hybrid inverter?
Pls love ur CC. A good CC will save u huge money eventually. left to me just ground Dat ur cc casing with d bus bar for grounding in ur setup. Don't ascribe to + or - earthing till u have funds for dc arrestor

Explore other options from guru pls.

goddyior24:
Good day Gurus.
I wish to know how to properly ground EPSOLAR VS3024AU pwm positive grounding solar controller with solar panels.

grounding was discussed few pages back. try and check to avoid repetition pls.

check these addition pages by Mank1234 =>https://www.nairaland.com/390522/solar-energy-complement-fta/151#47676906 and
https://www.nairaland.com/390522/solar-energy-complement-fta/151#47678332

chikkaobi:
Got Charge Controller MPPT30A for a single 200AH battery, however I saw Battery Capacity configuration which says >= 300AH(Meaning greater or equal to 300AH)
My question is; Can I still use this charge controller on a single 200AH battery without issue?

lets have your full config. or setup by listing them out. few pix can quicken your request from those with similar CC

you may also add your intended load!

alternatively go back to classroom by reading from page one.

Onosy:
Installer do give different prices for installation of a 5kva complete system.
As it stands now I don't even know what the best option, though someone suggested Nickel batteries or FLP batteries

Start small but go 4 d best

cooldipo:
Pls we need more contributions to this issue of limit pose by charge controller rating. In my case, I have a 12V inverter set up and a 30A Epever Tracer charger controller with 3 units of 150watt mono panels. The Max Pv input power is 390watt(12volts) 780watt(24volts) for the cc..... I was tempted to add one more panel even though the Maximum Power current is about 8.5A per panel. I wanted one more panel if 150watt for obvious reasons......bountiful harvest on days with less solar radiation which my supplier gave a nod to but my installer here gave me the scare that I run the xtra/over current...... Pls help me out with informed opinion. Thanks

Yes! under STC Max Pv input power is 390watt(12volts) 780watt(24volts) falls true for your CC
but will you always get those parameters harvested from your roof top?

Yes! you stand the risk of blowing up ur cc with the extra/over current
that is where you need learn from experience of gurus in the house.

for me, you can always tweak by re-configuration of your PV with installation of extra one PV having a slightly lower specs somewhere in your Series & parallel.

But observe the 145v / 30A thresholds.

bigrovar:
So yesterday I finished series of updates I have been carrying out on my system. The upgrades include an additional solar panel (250w) to my 240w+240w+220w array. I made was to replace my crudely put together battery monitor with victron Energy BMV 700 battery monitor. Comes with a shunt and display too.

Hope to do a product review on the BMV soon. (Fantastic product.)
Below are mandatory pictures

for sharing your experience, i say thank you !

i love your Tubular batteries too i wish recession should just go to purchase some too. the distance btw battery bank & CC + battery loop seems too long, but you seem to have solve energy loss using rated cables. Nice too!

i admire your monitoring meter and its basic installation. it re-buttress what konnection said earlier that we are like hawks watching over our power solutions.

I am not comfortable with your cables hanging or dangling from your PVs. I hope you don't have domestic goats around your place or else they may practice "head butt" with it or use horn to test their stamina to impress she-goats.

solar is truly renewable

goddyior24:
The EPSOLAR Tracer 2210RN 20A is rated at 260w maximum panels. I do not understand. I need clarity.

am sure you are referring to the following specs

Specification Summary
System Voltage 12 / 24VDC
Rated Battery Current 20A
Rated Load Current 20A
Max. PV Input Voltage**
Tracer-2210RN 100VDC
Tracer-2215RN 150VDC
Max. PV Input Power
12V System 260W
24V System 520W
*Array voltage should never exceed maximum PV input voltage. Refer to the solar module

if you read further on the manual you also find

"If the solar input current exceeds the maximum rating, the array will be disconnected automatically".

what stops you from configuring your panels on hot sunny day to get the upper limit since it has auto shutdown.

let us have your test results when you can carry it out.

goddyior24:
EPSOLAR Tracer 2210RN 20A mppt controller is rated at 260w maximum solar panels. If you want to go close to the 100v for more efficiency, your panels wattage will be more than the 260w. How can you get 80v still being within the 260w Limit?. I need clarity.

Is that what the manual says?
why not consult properly from dealers before buying items.
most solar enthusiast here will gladly offer you good -free advice without consultancy fee.

mind you 20A mppt cc cannot have upper limit of 260w
please do your sizing properly to enjoy your sweat otherwise you will think "solar thing" dont work .

bigrovar:
Avoid parallel connection if I can. Rather it's always better to go on higher voltage than current. Parallel connection no matter how well installed have a knack for not being evenly charged.

hmmmmmmmmmm Voltage (v) versus Current (amp)



lower voltage => lower heat more amps (mppt, pwm)
higher voltage => higher heat greater amps (mppt)

having battery-cable distance in view. hmmmm true talk!

GeorgeD1:
richmon,

welcome back from the cold.
no doubt 2017 is shaping up to be a very exciting year after all.

I completely agree with you. Oga richmon u've stayed away too long. I have everyone here to thank profusely b/cos am enjoying 24hrs electricity with style since I discovered the great house. Thank you all!

GeorgeD1:
dmerciful,
efuro,

the thermostat on the ariston is at its highest. and, no it was not a deliberate pre-set.

that said, i think it will be interesting to throw an open challenge to as many here with
electric water heaters in their homes. let's have snapshots of max temperatures of your
hot water and see how it compares with that of the solar water heater.
remember to set your thermostats at max.
let's bet against the sun!

confidence of Solar! thumbs up

juliustip:
I am tired of changing batteries every year(Used Mercury twice and some other deep cycle battery), is there any recommended 200AH battery that can go for 2 or 3 years straight?
Would appreciate your suggestion.

NB: Am on off-grid 2kva and always switch off power at 12.2v

i feel ur pain, batteries aren't cheap.

to my view, i believe batteries just don't die without a fight,

i believe batteries are constantly under-charged, you need to add more panels
Also work on your loads or double your present battery bank to considerably extend
their years of usage.

Living off grid is a good thing. pls make sure you add more panel before acquiring
new set of batteries. you will eventually smile.

DMerciful:
With current price(Fullriver @ 130K, Exide @ 200K, Mercury @ 115K etc) Lithium iron phosphate is cheaper in the medium term and far cheaper and super in the long term. It requires planning

i see your point
it is eventually cheaper and more efficient
(Fullriver @ 130K, Exide @ 200K, Mercury @ 115K ) recession is not good ooo

DMerciful:
The solar panels, CC and inverter are durable by design...the only challenge is periodic battery replenishment. That's y I'm switching from lead acid to Chinese LiFeO4! Will share a review when d time comes . However Lithium iron phosphate or iron Edison are the way forward! I'm done with sulphating lead acid!

Lithium iron phosphate or iron Edison
are for big boys!

i rather stay put with my go-slow SLA batteries with lesser loads

Jean2:
Interestingly, it is possible to use Solar power installation of less than 500WH for powering several equipment. Power cut (mains power outage) should not stop you from running your electronics... to be cont'd.

Can it be true that the strength of home solar applications is directly d strength of batteries?
My advocacy on AE has always been bedeviled with opinion that solar don't last and see no reason why they should fall in love with it as we do.
We need to prove to Nigerians that solar works and works well & remains d lifeline of electricity to millions of homes.

I salute the courage & works of great men here. It inspires millions to take their lives in their hands.

DMerciful:
The ariston has temperature setpoints adjustment and it can get quite hot if set high...but then sun gets really hot....as seen in solar electricity generation through heating of molten salt

That solves it.
It is a deliberate pre set. A valid point too

Thanks

GeorgeD1:
all,
out of curiosity i decided to measure the max temperature of my solar water heater and do a comparison with
a fully functioning electric water heater (ariston). the result was shocking even to me.

i knew the solar water heater really gets hot on a good day but i was really not prepared for the sharp difference
in max temperatures between the two.

see below pictures:

the sun truly is the answer!

Oga GeorgeD1 thank you for your innovative intuition

the forum is getting too boring that is why i try to introduce issues on equalization of different batteries few days ago.

i still find your discovery hard to believe, it's like a bitter pill. May be the ariston is on standby mode.
pls fire it up untill the thermostat switches it off and re-run/test your values.
am anxiously waiting to hear your results.

Good day House

can anyone tell me or link me with site showing standard days for equalization for SLA, FLA, AGM batteries

i observed AE enthusiast set equalization to 28 days, some to 32 days. i set mine to 14 days

or having BLS negates equalization of batteries ?

am kind of confused.

thanks !
