MY SETUP IS series 48v 4kw mustpower and i equalize every month or 3weeks,at 62v.its solely a phcn setup..no solar as phcn is fairly decent in my area 12 to 16hrs daily.
will consider swapping the batteries around to see if there would be any change, though i doubt.i also hv a desulphator permanently hooked up to the bank.
am guessing the batts may hv a factory defect, as my other set of mecury flooded are performing beta.

Even for lead acid there are 2v 500AH people buy 12pcs to give 24v

DMerciful:
Nope...there are compact 12v units from what i have seen in pictures.

These Nickel iron batteries popularly called iron edison after the inventor Thomas Edison has the capacity to last 40 years or more without appreciable depreciation. They require some level of maintenance usually water replacement however the recent ones have integrated automatic watering system. They are very expensive, ofcourse, with such longevity they ought to be.

Good evening house, I’m new into green energy. But I’ve been mandated to make a quotation for the installation of solar energy at a particular location.
My main concern is the client in concern is really interested in monitoring the solar setup over cctv and if possible controlling the setup. i.e the charging and discharge rate, watts stored, battery level, switch time from NEPA to solar.
House is this really possible as I’ve been mandated to research into this and give back a quotation for the projected to be kick started.
Thanks very much awaiting feedback from u guys. God Bless.

LiFeO4: The Review

As promised, here is the product review for the lithium iron phosphate (LiFeO4) battery I imported from China.

LiFeO4 batteries are among the newest technology which offers longer lifetimes, better power density (the rate that energy can be drawn from them) and are inherently safer than other lithium based batteries. LiFePO4 is finding a number of roles in vehicle use and backup power especially in home solar/inverter applications. It is said to deliver over 2000cycles (5.5yrs if used every day) at 80% DOD and about 5000 cycles if used btw 30%-50% DOD(13yrs!!!) hence my attraction to this technology.

Packaging
The battery is house in a plastic container formed into a briefcase style design. I will rate the casing fair but will expect improvement in its structural integrity as time goes on.

It weighs about 13kg for 12V, 100AH battery and this weight is consistent with Lithium iron phosphate due to the presence of iron which is quite a heavy element unlike lithium polymer that is lighter(lithium polymer[phone batteries] are not as long lasting as lithium iron phosphate).

Internal Construction
As a DIY guy, I needed to see what’s inside this expensive box, so I opened it up. I wasn’t impressed. The cells were crudely put together, poor wiring with electrical tapes/foam packing holding wires/cells together…I was like what the hell!

@dapsyra, DMerciful, Konnektions146, Ferdiwar and everyone.

Thanks all. My Inverter is 24V. Planning to upgrade to a 48V soon hence the reason for the diagrams.

I think i will go with the serial-parallel for now and change to series when i upgrade the Inverter. Hope that will work?


NB: I stumbled on a link with facts and figures - http://www.smartgauge.co.uk/batt_con.html which will make a good read for forum members.

Hello guys,

Been thinking of the best and most efficient 4 Battery setup. Can you guys assist me in choosing a good connection out of the 2 options and the reason. Thanks.

Gaston is gel. I don't like gel...they are too sensitive and prone to failure if abused or if charging system is not right!

DMerciful:
If u've d funds...go for iron edison, LiFeO4, deka, quanta, UK zenith,Fullriver,sulkam in this order

davodyguy:


Thanks, just that most fat heavy ones are from China and the slim batteries are US.

I was offered slim batteries at the rate of 110k each and the fat heavy ones at 90k each, so I'm wondering which is more durable, owing to the price difference?

Xperia custom rom is the best of them all. It has no bug at all. In cm11,the file manager has a bug cos u cannot delete and also neither can u copy nor paste therein, but xperia is just perfect even the file manager is upgradable and xposed framework works just fine. Skygee wa gbayi…… Thankz do much. Here are my screenshots
