Gentlemen, I came back home yesterday and met the breaker triped off (the positive one in between my solar CC and the batteries) so I turned it on and immediately I hard a noise from inverter, well I checked and nothing seems unusual. This morning I noticed the CC was on and charging but showing zero reading for watt and amp and even when the positive breaker is off (am thinking maybe the breaker has gone bad) though there was grid supply throughout the night uptill this morning why will the CC be charging? Or could it be that the inverter charger is not working?

Hello folks,

Does anyone know where i can get an Axpert Type 5kva Hybrid inverter (its actually an mpp solar brand but i think there all the same generic design) repaired?


Does anyone have a 2kva 24v used inverter for sale? (preferably in ibadan)


thanks

Am not really a fan mercury products sir.

Thanks for the offer though

Which make are they? The ones I have is rated 15,000cycles only

GTK. Chinese brand. All research points to 100,000 cycles

Already too much. I feel anything over 10,000 cycles at 80% DOD is more than fine in this current age if its to be cycled daily, which i feel its what we use for now. I'm pretty sure it's gonna weigh alot more than other Li-ion batteries out there.

Weight is same range just a superior use of nano technology. Price is just a little more the LiFeO4

How does one verify these batteries can do 100,000 cycles?

Again 100,000 cycles at what Depth of Discharge?

I wish you had brought out this advert 4 months ago before I invested in my 800AH lead acid bank.

I would take this as strictly hype until someone shows data to prove otherwise.

These are extrapolated data.....who don live 277years . Based on testing there is zero capacity loss in 5years(so they say sha)! and it can be charger in 6mins! the next 5yrs will be super interesting

My Oga you are seeing what I am seeing.

If all this is true then I am hooked - 20+ years of service is enough for me.

If I had performance assurances, I can jettison my current bank and go with these LTO batteries.

6 mins!!!! Chaiiii. Wait ooo. Let me do small maths. That means for the 24V battery...
210A (1C) to charge it from 0% to 100% SOC in 1 hr/60mins
2100A (10C) to charge it from 0% to 100% in 6 mins
1050A (5C) from 50% to 100% in 6 mins
210A (1C) from 90% to 100% in 6 mins

So in a power loss-free scenario, it'll stilltsje 5C to charge it in 6 mins from 50% DOD... 1050A. Please tell me if I'm wrong ooo. Make i run take cover

Of course there are performance assurances at least for the Japanese made brands.

LTO chemistry was invented more than 12years ago and had since been adopted by the US military.

During a project last year, I came across some LTO cells manufactured in January, 2008 by Altairnano for the US Navy and stored away at 0V. The cells were in sealed cartons with date stamps on them. They were 55AH cells. I physically measured the voltage and it read 0V.

I then charged some of cells to 2.8v at 0.2C and they took in 54 to 57AH. Several charge/discharge cycles later indicated that they have not suffered any noticeable performance degradation after hibernating at 0v for almost 10years.

The major downsides of the LTO batteries are the very high price, low operating voltages and low energy density relative to other Lithium flavours. But now that the Chinese have started manufacturing them, prices will nose dive quickly.

Their major advantages are:
1. Extremely long shelve and cycle lives (10,000 - 40,000 cycles for the ones I have seen). Chinese are now advertising 100,000cycles
2. Ability to perform under extreme temperatures ( -30 to 60 degree Celsius)
3. Very high charge rates ( up to 10C )
4. High discharge rate (up to 10C )
5. Discharge to 100% DOD
6. Tolerant of overcharge without bursting into flames.

1050A x nominal 24V = 25kW power draw during charging . . .

Your street transformer go catch fire

Literally !!!

Biko tell me the price expectation (landed cost to Lagos) for a 48v 500AH equivalent battery bank - I know people who would be happy to give this battery technology a try.

I can PM you directly if you prefer.

Yes Dapsyra, I'm very much interested in same spec below.

For 48v 500AH (24KwH), expect to pay between N7m - N10m for the cells only depending on type and manufacturer. You will still have to DIY the cells into modules, buy containers, interconnect buss bars, BMS etc.

EV power is rating similar units at 50,000 cycles for 0.5 C discharge and 20,000 for 1C

Note the item is marked as a sample and not commercial use.

https://www.ev-power.eu/LTO-technology/Lithium-Titanate-Oxid-Battery-Cell-LTO-2-4V-30AH.html

In my opinion, the technology is yet to mature (BMS, charge controller and inverter support )

But if you are looking for long life even zinc bromide is also promising with relatively modest charge requirements and ability to maintain battry life even at fully discharged state

At US$56,000.00 (N20.5M) for 20kwh, I would rather stay with LTO

Your source may be referring to the containerized Zcell price of the combined unit ( 60 KWH upwards) for commercial applications
Zcell dropped by half in price in 2016 and with the new factory in Thailand it should still come down. 10 KWH is approx 8000 USD ( 2.5 to 3 million Naira)

Good morning guys,

What do you guys think about Saroda All in one Solar power ⛮ needs?

They have solar panels, inverter and battery packaged as one item for "plug and play". No monthly charges like luminous of mtn, so they say.

I need reviews about it. Because this is what I want to buy next.

Have anyone tested it?... Is it reliable,?

Check them out on alibaba

https://sarodapower.en.alibaba.com/product/60657615962-804619188/SARODA_1500w_all_in_one_portable_solar_power_station_solar_energy_storage_system_off_gird_mico_power_generator.html

More on their design and company information

Even Jumia have their 100 watts. I am tempted to order this for testing first before going for the 1.5 KW.

Someone should throw more light � on their efficiency

And why is their battery � capacity saying 7000mAH for a 100W setup? Are we talking about power banks here ?

Please i need more explanation o

Thanks

omo u over do the posting of pics/details.
this is a diy thread, few folks would be interested in such.
you isolate the individual components..and compare the cost of each in the open market...then you decide if its worth it or not..
for me and my family..i dont patronize all thse combo packages, doesnt make any sense..all man wan make profit. so they will likely throw is a couple of substandard products in the mix, tier 3 products

Hello, the poster above made reasonable points .. I have seen similar package in Yingli and other makes but I have never advised any of my client to invest in that miniature all in 1 solar kit ! Its best you invest in a lasting solution which you would enjoy the value of your money with your family ! Cheer's
