will do

like I mentioned earlier, it took just over a year to collect, cause of my location, if I were in Lagos maybe just one day or two as long as the cash dey o

they are all so-called "dead laptop battery"

will keep you informed on the setup finally

thanks

WAITING TOO. ESP HOW YOU WERE ABLE TO TEST CAPACITY FOR SUCH HUGE NUMBER OF CELLS. I KNW YOU HAVE TO CHARGE AND LET SIT FOR A WHILE OR DISCHARGE UNDER A MONITORED LOAD TO TE BE ABLE TO TEST CAPACITY.

IM FOLLOWING YOU NOW.

[quote author=totalgreen01 post=78601673][/quote]WOW...THAT PUT THE P IN POWERWALL!...CONGRATS BRO. WE WILL TALK ABEG. THIS IS WHAT IV BEEN LOOKING FOR.

Kampack:
Please has anyone here used GBM batteries? How durable are they?

Are they better than Croc batteries? Im torn between choosing one of the two. Kindly advice from experience.

I USE GBM, HAVE NOT USED CROC. SO FAR SO GOOD...IV NOT USED MINE BELOW 12.4V THOUGH. KEEP IN MIND, FOR ANY SLA BATTERY CHARGING AND DISCHARGING PROFILES ARE KEY TO THEIR DURABILITY OR NOT

zeanslim:
hello, I need 1kv+ APC UPS without battery the 12v pure sine wave version, or cheap pure sine wave inverter.

I'm planing to build an inverter on budget using 18650 li ion battery cells which I have began assembling.

I stay in Lagos if anybody have for sale.

FROM MY RESEARCH, THERE IS NO APC 12V PURE SINE WAVE UPS AVAILABLE. ALL PURE SINE WAVE ARE 24V.

CSNg:
To tell you the truth, I am as puzzled as you are because a day after writing that comment, I used a "small transformer" 1000w inverter and then tried my hands on a bluegate 600va UPS with the normal bigger transformer. I plugged a clamp metre while using both and compared only me to notice that the battery was draining faster with the inverter than it was with the UPS!

Quite confusing!

Does anyone know why?

LOL...ALWAYS CHECK THE PRODUCT SPECS FOR ITS EFFICIENCY RATING. MY APC 650VA UPS I GOT LAST WEEK FOR LESS THAN #6,000 DRAWS ABOUT 0.8A ON NO LOAD. THATS ABOUT 10W ON NO LOAD OH. BUT MY BATTERY IS A 180AHR CAPACITY PLUS A LITTLE SOLAR TO KEEP IT TRICKLE CHARGED DURING THE DAY TIME. SO I DNT BOTHER ABOUT IT.

ALSO WHEN NOT IN USE, I TURN THE UPS OFF.

Kampack:
Can anyone kindly recommend a durable, pocket friendly & good product, or seller for 12v DC Ceiling Fan?

ONE GUY JUO DOES SELL AND SOMEONE REVIEWED HIS PRODUCT AS WORKING FINE

officialfestus:
Who can help me get a 650va ups without battery from Lagos to Benin?

THE WAYBILL WILL MAKE THIS NON ECONOMICAL. JUST LOOK AROUND ELECTONICS MARKET AND ASK WHERE TO BUY USED UPS. ALL THOSE ABOKI THAT BUY SCRAP ELECTRONIS AND METAL MAY KNOW WHERE YOU CAN CHECK.

temizeee:
hello house and good day please i need advice on a good rechargeable fan that can be use for a single room......maybe experience from current user can help too..thanks

I USE BINATONE. IT BLOWS ENOUGH TO MAKE YOU CACTH A COLD IF USED ALL THROUGH THE NIGHT

odimbannamdi:
For his battery capacity (2 units of 100ah), what capacity of solar panels and chargw controllers should he have used?

Mine is a 100ah and i am considering something along that line. My major fear is mistakenly buying a modified sinewave UPS again, even though i now use a DC rechargeable fan. Does MSW UPs have adverse effects on TVs and sound systems?

Pls advise

MSW UPS AND INVERTERS HAVE THEIR WORST EFFECTS ON INDUCTIVE LOADS ( IE DEVICES THAT HAVE COILS IN THEM LIKE FAN, MOTORS, BLENDERS, ETC). YOUR RECHARGEABLE FAN USUALLY HAS AN ELECTRONIC CIRCUIT THAT CONVERTS THE AC TO DC WHICH THE FAN USES SO YOU SHOULD BE FINE USING AN MSW ON A RECHARGEABLE FAN. THATS WHAT I USE TOO WITH NO ISSUES AT ALL. MODERN TV MOST LIKELY USE DC INSIDE THEM SO YOU SHOULD BE FINE TOO. SOUND SYSTEMS TOO

Hello house. I am a complete novice. i was using a 3.5kva inverter before. The four batteries got flat and i am planning to upgrade to solar. The quotation i got is for different solutions.
1 SOLAR LIGHTNING...This is just to power about 33 bulbs
He said he will bring 33 solar bulbs, 6 solar panels, 2 controllers, 2 200ah batteries.
This package cost 500k.
2 SOLAR FAN PACKAGE= he will bring 9 solar fans, 3 batteries 100ah, 3 solar panels, 1 controller. This package cost 480k
3 A package for just two TVS and one computer= 3 solar panels, 1 controller, 2 batteries 150ah, one inverter 1.2kva.
This package cost 300k. total is one million, two hundrend and eighty thousand.
The package appears interesting to me because different solutions are controlling the light, the fans and the TV so all cant go down at once but i dont know wether the package is a good idea . He promised that we can even go off the grid for the fans, light and tv and then use generator when we want or PHCN for freezers etc.

If you assemble one, well sized unit to take care of all these stated loads i have a gut feeling you will save some bucks and still get good value for your money. You just need to know how to "use" battery backup systems.

Talk to the intelligent installers here and you will be glad you did. JUO, NIYI, KIEKIE, and a host of others are at your service.

House,
Good evening.
From experience of the seniors in the house.
What model 5KVA, 48V Inverter will you recommend with a good charging current, display unit etc., apart from Magnum, Outback, Schneider, Victron, I mean a good product but not as costly as those mentioned above.
Thanks in advance for your advice.

Check fangpusun inverters, the company seems to have good products at cheap prices.

Runx:
The Victronconnect app is one the most accurate there is for monitoring solar and battery system. The app check for older firmware before it can you grant access to the app then update as appropriate. Nothing stop you from using your device out of the box.
If you so decide to update later with the latest firmware please do so. The problem appear to be earlier firmware updates which the latest firmware have superceded without issues.

Thanks for commenting.But i didn't quite get the explanation. Do you mean the Victronconnect app does a firmware update of the scc automatically if one tries to use the app with the SCC? and if yes, that i should update with only the latest firmware without fear of killing the SCC?

bigrovar:
Me labout 3 years ago. I tried all that trick and still have the 150/45 fangpusun under a able somewhere in retirement. Hoping to one day put it under the axe and use the internals while secretly waiting for the hardware hacker community to take up the challenge.. maybe someday. I hope u succeed way I did not.

sir, is it a must to upgrade these fangpusun scc? cant it be used asis? i want to get a couple of them bt im concerned with these issues with updates and slow deaths.

Saipro:
I haven't tried it but I think there's a solution called Fronius Eco or something similar. It's standalone and starts at 25kVA, if I recall right.

While an overkill for your 10kW of loads, it might be up your alley. Otherwise, search amongst Indian inverters. You should strike gold there.

We use Fronius Eco (25kw) and Fronius Symo (15kw) in my coys installations. It needs an ac supply to ride on before it works. i dont know if thats what they refer to as priming here

A question put forward by a DIY
Tracer 3210A vs Fangpusun 30/100

Gurus in the house, please which is better between Epever Tracer3210A and Fangpusun MPPT100/30A. I realize that they are both mppt cc and that the Epever has a screen while the Fangpusun requires an external display. Is there anyone here who has used both and can make informed comments about their real life performance. Thanks

Answer by Bobby:
I have used both controllers extensively below are my observations.

I would skip the obvious similarities between both controllers mainly rated Amp and input voltage limits. And talk mostly about areas they diverge.

Manufacturer: Both are made in China by Chinese companies. The Tracer is an original product made by the company Epsolar while the other is a clone of the popular victron energy blues solar . Both companies seem to have good support and respect their warranties without much hassle. At least from my experience.

Heat management: Both are fanless and rely on heats sink for cooling. The Fangpusun has the better thermal management because it is made from one sheet of cast iron. The tracer has a cast iron dedicated heat sink but the whole body is made of plastic.

MPPT Tracking: Both have very good mppt tracking capabilities however the tracer can be unstable sometimes it restart more than once in day to day use. The Fangpusun from my experience has better tracking algorithm especially in cloudy situations. It is also very stable and I have never noticed it restart.

Battery charging: Both controllers use the 3 stage battery charging formula. The difference is the absorption end stage. While the Tracer series uses a time based absorption end settings which is user adjusted. (default is 2 hours) the Fangpusun uses a combination of end Amps, Battery voltage and length of bulk time to determine when to end absorption stage for battery. Both methods have their plus and minus. The tracer series can be frustrating especially when the battery just got to float and temporarily dropped back to bulk due to a passing cloud. This would cause the controller to do another round of 2 hours mandatory absorption. Even if the drop to bulk happened for just 5 minutes. This arrangement is not idea for the longevity of a battery bank. Fangpusun fixes this issue by using a mix of time, Battery resistance determined by how much amps the battery can still take, length of time to bulk and initial battery voltage during the charge cycle. This ensures that absorption time varies depending on the battery state if charge. The downside is sometimes the charge algorithm can be so short the battery spend less time in absorption than is not good for its wellbeing.

Equalization: Both controllers have settings for periodic equalization. Tracer allows users to set numbers of hours an equalization takes. Fangpusun equalization time is determined by algorithm.

Accessories and addons: Tracer has support for External temperature sensors for temperature adjusted battery charging. Wireless and RJ45 connectors for interfacing with computer and mobile devices. Fangpusun supports victron energy’s smart Bluetooth dongle and VE direct USB cable.

Support software: Victron energy can be configured using the victron connect software which runs on Android devices, Windows iPhone and Mac. The victron connect supports firmware of the device firmware (although recent updates from victron has started to disable the Fangpusun Chinese clones). Tracer has the power station for the PC which compared the the victron connect is very basic and can be a pain to install. They also have wireless dongle which allows an Android device to interface with the controller

Log and Stats. Fangpusun has way better stats and logging capabilities. It takes 30 days log of events with each day having stats on Total kwh harvested, Pick Watt, max and minimum Pv and battery voltage, length of time spent in bulk, absorption and float and ability to export history log to csv format for viewing from spreadsheets. Tracer is pretty basic and only keeps log of total harvest for the day and total controller harvest.
Form factor : The Fangpusun has a smaller form factor than the tracer.

Display: Fangpusun comes with no built in display but allows connections using an external display. Tracers has display built in but the display is very limited and had no back light.

External display: Both devices support external displays. The Fangpusun support the mppt control while the Tracer support the MT50. The later is more user friendly and provide more screen estate.

Over all. The superior tracking capabilities, stability and better history support of the Fangpusun wins it for me.

A big thank you to all who learnt a voice to my question. I am grateful!

NiyiOmoIyunade:
In my opinion, the Fangpusun Bluesolar clone has no equal in performance and price and available configuration options when compared to similar CCs in its class.

I benchmarked it's solar output performance vs MorningStar and it did very very well even though I hate to admit it The MorningStar will only beat it because one can set longer absorb times e.t.c but the Fangpusun bluesolar appears to follow it's own default algorithm for length of absorb based on voltage at start of charge and time spent in bulk (custom settings may be made but does not appear to obey them)

I believe for this budget installation, you are looking for the 12v/24v version rated 100v/50a at the PV end. Ogas JUO or DMerciful can supply you this at a good price.

Thnk you Sir Niyi.....Mr dependable!

And permit me to comment about your writing style. It's music to the eyes. Well done sir.

HI MY OGAS, only late at night like this do i sometimes have time to read up on old posts here. the info here is priceless

Please, i want to ask between epever mppt cc, makeskyblue, and fanpusun smartsolar clones, which is ok to get for a budget installation of 12 v and 2 pcs of 200ahr battery installation? or any other suggestion

Thank you in anticipation

UPS and Power Inverter:

UPS - UPS or the uninterruptible power supply makes use of an internal inverter to convert DC power to AC. Then it stores power in its built-in battery.

Power Inverter – The inverter is generally connected to an exterior DC source to maintain continuous AC current flow. In this case, a standalone battery or batteries are used for storing energy.

Basic difference:

In UPS, the switchover to backup power is prompt, while in an inverter there is a little delay. This break is acceptable on household appliances like fans, lights, and fridge, but it is not suitable for sensitive equipment like computers and printers. Such delays can cause system crash and data loss.
It uses the main supply line for sending power to various appliances at homes or offices. Unlike the UPS, it is not directly plugged to the appliances.
Technical variance:
UPS – In UPS, the AC from the main power is transformed to DC. This DC is continuously charging the battery. The DC output from the battery is fed to a sine waveform inverter that converts it into AC and supplies it to the equipment.
The energy is regularly drawn from battery, and hence there no gap during the outage on the main. The battery stops getting charged now, but the UPS continues its power supply till the battery gets completely discharged.

Inverter – The main power AC is supplied to the inverter, and it is transformed into DC simultaneously, which keeps charging the battery continuously. There is a sensor and relay structure that always monitors the ON or OFF status of the main.
As soon as there is a power failure, the relay actuator activates the inverter switch. Every other action is similar to the UPS, but because of the sensor and relay process, there is a delay while activating the switch.
Circuitry dissimilarity
Circuits used in making UPS are very expensive than the ones used in an inverter. This is the reason why UPS systems are expensive.
UPS generally comprises:
Rectifier or charger – Rectifier transforms the AC current from the main to DC current, to charge the battery
Inverter – It converts the DC voltage from the battery to AC current, to the electrical equipment
Controller – It regulates the functions of both the rectifier and the inverter.
Inverter comprises:
Inverter – Firstly it converts AC of the main to DC for battery charging. Then it changes the DC power from the battery to AC current, and that flows to the electronic equipment
Controller – It manages the inverter functions

Pls dat 700 one in the below pix, is it pure sine?

Edit: just checked. Its puresine. Wish i can lay hands on it as it looks like a 12v variant.

feflo:
Couple back and its ready to go

Apc has a lot of models oh.... I wonder why the population.

My own 650va is diff from this totally in design.

Valto:
always connectted,but i rarely used again souer since i started using 24V setup. i charge with solar now.

ALWAYs comnected??... So why are these ones roasting themselves up naaaa.

I envy your solar option. Landlord no gree some of us enjoy am as we for want. Can i have your souer charger if you want to sell pls.

Valto:
seem your ups is not pure sine wave, whats is the Make? its not really advisable to use a regular AC fan on small ups/inverter. look for a 12v/rechargeable fans. it works better and consume far less energy.

i have used two 12v smart chargers( analog and digital) and none have issues. seems am lucky

get the digital version of the blue souer, i believe its stronger and works better
i doubt if it can damage your new rechargeable fan.maybe u should get an APC 12v 1000VA ups. i av seen the inside components of bluegate & APC. APC is by far stronger & better( real copper transformer) cheers

Pls when using your souer chargers, is your ups connected to grid too? Or you just use as inverter only?

Valto:
maybe 12V APC 1000VA is different then. i use 24V APC 1500VA. it works far batter than my other 12V bluegate 1.5kVA. i do use regular ac fan attimes, and it works well, but vibrate/hums a bit when i use 12V bluegate 1.5kva.

You are correct, i just talked with your contact and he confirmed that puresine ups comes in only 24v variant.

KingSatan:
Mr. Ceejay, please can you update me on prices for the fairly used batteries?

I really need to get a set of Fairy used batteries for my Inverter setup but i want you to refer me to your dealer in Lagos. As the new ones i bought have packed up not up to 4 months and i have angrily disposed them. I need 12v 200ah batteries

I am in Abuja

Hmmmm, very sorry bro.

How did you use the battery? Did u follow best practices in usage??

What most people dont like to hear is that using of batteries as backuo power isn't the holy grail_lots of battery babysitting, energy usage consciousness, appropriate charging and discharging concerns.

If you abuse your new batteries, fairly used batteries will even make you regret further. Pls make sure you aren't abusing your batteries and they won't insult your wallet.

Cheers
