@ George_D,
I have been trying to get in touch with my battery supplier in Lagos but could not at this moment. I think he still have some 260 Amp hour batteries. One 260 amp battery weighs 80kg

@ All,

Some tips to make your batteries last longer.

1) Recharge your batteries slowly (using automated charger/charge controller). Do not take your batteries to local battery chargers by the road side.

2)  Recharge a your batteries as soon as possible after each use to prevent sulfation.

3) .High ambient temperatures will shorten your battery life. Store in a cold dry place. Not in the fridge.

4)  Avoid draining your batteries too deep if you do not have deep cycle batteries. Shallower depth-of-discharge will increases your battery life.

5) When in storage, recharge when the state-of-charge drops to 80% to prevent lead sulfation.

6) Do not mix used batteries with new ones. The used batteries will act as load

7) keep your batteries well maintained. Clean the terminals when required.

Conduct regular routine battery discharge test.

9) Never discharge below 10.5 volts.

butoneday,
thanks for the wonderful tips. i'm sure many peeps here will find them useful.

if your battery supplier still has the 260ah battery spec then perhaps i'll like to talk to him.

@ George_D,
I will continue to the line of the battery seller. I hope to see you next week in town.

@All,
I saw some battries rated 20V 2500amp. The type is HOPPECKE made by the Germans. A company is currently using it for back up power to their system. Can three of these batteries work with a 48V solar/inverter system? Or can 5 pcs work with a 96V solar/inver system?

butoneday,
thanks for the update. we will talk better when we see in town next week.


those 20v batteries will be 60v for 3 (three) in series which can be used for a 48v system.
same thing goes for 5 (five) pcs which will be 100v and can be used for a 96v system.

remember that even the so-called 12v batteries are just nominal name plate values.
practically when measured they give a voltage above that, some even up to 17 volts!

@George_D, The time to snatch it, is now.

Guys welldone. good job. this battery 20v 2500ah is it available in d market and what is price look like?

Assuming I have a facility that will consume 10Kw/day, what specifications will I need and how much will that cost?
Thank you George D and anyone who can answer.

agabaI23,
with 10kwh a day, your specs are rather pretty straight forward.

this is what my pv software threw up:

battery bank capacity: 260ah (4pcs 12v 260ah batteries connected in series to make 48v)

solar array: 4650wp which is 24pcs of 200w solar panels or 48pcs 100w panels (it could be of any configuration - provided it sums up to 4650 watts)

Can you put a single price to all that pls?

agaba123,
1pc 260ah zenith battery (last time i checked) 65k
1pc 200w sharp solar panel 85 - 90k

Thanks a million.
If you are to install this for me, how much will you charge?

Thanks man for your reply.

pls,how can i convert mp pc UPS to inverter to power tv and my decoder only

@ Akerekoroabijawara,

The conversion is simple. Just open the UPS cover, connect two wires from the battery terminals inside the UPS to an external battery (s). Connect positive to positive and negative to negative. Your TV and Decoder can now run for hours.

hello agaba,
i don't do installs for clients but i can always direct you on how to go about it.

but if you live anywhere near warri of course i can lend a helping hand.

butoneday,

agaba,
all,

i contacted pecorns in canada concerning the hoppecke batteries and he's very much willing to help us out. however, there is no 20v 2500ah specs. i think butoneday meant 2v 2500ah. even their website also confirms it. for those interested, i'll be sending personal mails on details how we can pool resources together. although the cost is a bit high but personally i think it is worth it considering the number of days of autonomy one can get from a single charge.

GD thanks. it is ok. will be expecting ur message. if they hv it in 6V you can also enquire.

idsolar,
you got mail!

@all,
anybody interested in 6v 420ah trojan batteries and large wattage solar panels (up to 295w each) should let me know. i'm presently compiling a list of members who wants to pool resources together so we can bring them in directly from the usa.

urgent response is needed pls!

check out the trojan specs here:

and the 295w solar panels (canadian solar):

http://www.dmsolar.com/csimosomo29p.html

@all,
in addition to the 6v 420ah trojan batteries and 295w canadian solar panels above,

there is a battery de-sulpahator on offer. it can be used to revive dead or weak batteries.
it is a must have for anyone using deep cycle batteries. check the link here:

https://www.battery-rechargeable-charger.com/Store/products-page/battery-life-saver/bls-48a/

price is 25k.

anybody interested should let me know.

i'm already placing an order for mine.

i am interested, am presently in ph, cud u throw more light on the charging capacity of the 295w solar panel, how long wud it take to charge a 420ah battery

@ george_D Am interested man. I have not setled down from my journey that's why I haven't mailed u

earthrealm,
believe me this is the best offer anyone can get in these parts.

to your question, the rate of charge of a battery depends on the charging current. a typical 295w canadian solar panel will give 8.1amps (max). you will need a minimum of 4pcs of these connected in series-parallel to give 16.2amps. with this, you can charge your battery bank to full capacity in 4 - 6 hours, depending on your usage and available sunshine.


take a look at this link. you can input the values into the calculator yourself:

@ george_D Am interested man. I have not setled down from my journey that's why I haven't mailed u

adex,
thanks for your response. you are welcome back. please as soon as you settle down
let me know how many pieces you will need so we can place a bulk order for the items.

all,
i have been able to secure rock bottom prices for the 6v 420ah trojan batteries and the 295w canadian solar panels. details below:

updated:

1pc 6v 420ah trojan battery - landing price 42k each
1pc 295w canadian solar panels - landing price 75k

this is an irresistible offer no one should miss. personally i'm siezing this opportunity to
begin building up my bank 2 batteries and panels. any person also interested should let me
me know so that we can order them in bulk. that way we may even succeed in bringing the
price further down.

note: this is a pre-order direct from canada.
those who are used to this will understand what i mean.

George_D

It seems that I will get some of the 295w panels. I will inform you of the quantity in a few days time.

For the 6v 420 amp Trojan, here are the physical details or dimensions of the battery

Lengh t= 11.6 inch

Width = 7 inch

Height= 16.8 inch

Weight = 114 lbs

For 12v 450amps, the details are:

Length = 19.3 inch

Width = 10.6 inch

Height = 16.8 inch

Weight = 332 lbs

Which one will you go for George_D? See also the link below for more specs

http://www.hodgsoncorp.com/products/trojan.htm

hello butoneday,
thanks for your interest in the solar panels. i'm placing an order for eight pieces so if you can make up your mind fast enough maybe we can do it together.

as for the batteries, what i'm talking about is specifically the 6v 420ah specs:

http://www.energymatters.com.au/trojan-flooded-lead-acid-battery-6v-420ah-p-204.html

at 42k each, it is a very good bargain all things considered.

i'm ordering for eight pieces of them since that will be the minimum number i need to make up my 48v battery bank.

@ George_D,
Yeah good move. You have to do it quickly to increase your back up at night. For now, am still observing my new installation and so I cannot say what I really need right now.

@Goerge_D,
You got mail.
