i usually say it that most installers dont understand the physics behind what they are doing, hence NA SO WE DEY DO AM IS THEIR MOTTO..

they dont understand difference btw mppt and pwm cc, an dont bother reading manual as well..hence they treat and connect every CC as pwm..

Many in Benin don't even know what is lithium batteries, engage with different installers they where telling me they only use tubular batteries that it is the best.

On the CC u are right all they know is charge controller

I just told them their customers dey try

Nice job.

@ 43 sec, you mentioned "the 1 horsepower inverter AC that is barely performing..."

Was that a derogatory or complement for the inverter AC?

Those batteries that are 100% full at around 1pm, what is the capacity?

Yes the AC sucks. Only cools the room on cold nights. During the day it struggles to keep the room at 27. My window non inverter AC does a better job
The batteries are 5 kwh. I have 4.3 kwh in PV. Thank you for watching and commenting

earthrealm:


Superb inverter, made by China.
China is vexing these days.
Producing premium products at non premium price.
The german or american version of this would cost a section of ones liver

Wait for the day Niyiomolade would go fully chinese .

My brother they are blowing my mind. I retired my Victron and Schneider products. This inverter and battery are IP65 rated. The inverter has a 120 amp AC charge and a 10 kw surge.

ojeysky:


I love the "time of use" feature on the inverter, in my case I use solpiplog to schedule that for my inverter. What kind of cooker are you using that is consuming 1.2kw? Is it the typical ones as I think those consumes more than that?

Not just in Benin my brother, it's generally across the country. I started procurement of extra lithium accessories whenever I placed order for my use with the expectation of selling (at 15 to 25% profit margin) to those who needed urgently and can't wait for overseas procurement.
Let's just say I may have overestimated the demand o

Okay this is interesting, one man's food is indeed another man's poison. Are you able to check consumption directly off the battery? If yes, what's the DC power consumption with an AC load of e.g 500w and the no load consumption?

The battery communicates with the inverter. So it does tell the inverter. The inverter consumes about 50 watts.

The poor performance of the Ac, maybe mechanical.
Perhaps it has a leak, and needs topping up.
Why not get an ac tech to look at it.

From what my chinese yingli panels are producing, i passed up the chance to buy 350w canadian for 50k, and went for yingli 320w @ 44k....sounds crazy huh..
For a 1680w array to hit over 2kw instantenous production, am yet to hear such from a canadian panel user.

Based on competitiveness, price & functionality.
Mpp& Sorotec appear to be the kings, phocos coming a distant 3rd and then this your Deye.

Only time will tell how they hold up over the years.
I hope anybody buying these high pv input hybrids hol im side knowledge wise...cos these half baked installers will connect 3s4p for you..sending 100v to a n inverter that requires 120v minimum start up voltage..and then turn around to tell u that...
Oga this inverter wey you buy no good!!
Return am

Yingli panels should be good, though i haven't tried my hands on any yet(still looking at it with one eye).

chris81964:

That's quite fine for a 5kva, how about the efficiency part i.e when a load of AC 500w is put on the battery, what does the inverter reports as consumption? With 500w AC load on mine, the DC consumption is about 570w to 580w, so it consumes more as load increases...even though no load consumption is about 28w.

Edit: noticed a typo on my stats it's 570, certainly not 670

I think we've discussed this, you were just most likely lucky to have received a wrongly labelled panel, on the positive side though

What's the price range of Deye because I think it's features may actually floor that of MPP.

Hahahaha.....I also hope that someone planning to buy those high PV inverters will not be working with the lower band (120v) you should get at least 250V PV before you can get a good use the inverter. There is no start small small in high PV inverters o

People are thrilled at how the solar energy accessories work. The ones I use, I bought them personally, also read about how they work and calculated my appliance before buying. I also researched about the battery and bought Amaron Quanta, as I read so many testimonies about how it is good. That's 3 years ago and it's still serving.

Nigeria has not fully embraced RE yet but we are making progress. It's not cheap but it's a better alternative to what's already in place.

I like the fact that the inverter did not seem to increase its fan speed at that load, though since it's 5kva, the load would be about 30%, nice to have inverter I must say!

If you mention anything solar, they would ask "does it work and can it carry fridge?". Just the way people think corona virus and similar stuff are unreal, a lot more think solar is a scam. They don't see it as a worthwhile venture.

Oops! Sorry about that.

Could this be a one off bad experience? Hope it isn't a common thing with inverter ACs.

Users of inverter ACs here, your input may be required.

Meanwhile, got a 12v orbit fan installed a week ago, costs 12k. Three speed and works fine so far. Strictly connected to 12v DC for now, I intend to connect an external AC power pack to measure the consumption later as the inverter freezer is monopolizing the wattmeter at the moment. The nameplate says 12 watts though.

So I got to confirm the consumption. It only has DC to DC cables included. It does not come with AC power pack included unlike the Qasa AC/DC standing fan (the type Ojeysky has in that picture) that has both AC power pack and crocodile clips to DC plugs included. So I used the power pack included in the latter. It's rated 230vac 12vdc 2amp plug.

At speed 1 - 9 watts
At speed 2 - 11 watts
At speed 3 - 15 watts.

It blows air impressively down a 9 feet ceiling at all speeds.

How many pieces will give a 24v setup. Gud morning.

I currently have 9 (250W) panels in a 3S3P config mated to a Fangpusan 150V-70A charge controller on a 48V battery bank. I am thinking of adding 3 additional panels to this. Which is it safer for the CC - to have the panels in 4S3P OR 3S4P configuration?

Would have preferred the 4S3P as the cables I have already run can take the additional panels and I wouldn't want to be running additional cables to my cc.

Stick with 3s4p setup.
The FP 150|70A has a max VOC of 145V. Doing 4x250 in series will exceed this limit.

I'm not so sure 250 watts in 4s will not exceed the 150V voc of the CC. Perhaps a nameplate of your panel posted here may help or those with idea of the voc of 250 watts panel can help.

Your present 3s config seems to provide adequate headroom for your CC to handle the 48v charging and additions should be more of parallel going forward. I don't have much knowledge of the Fangpusuns though, but that's what I think obtain for most MPPTs I've encountered.

Edited: I see @ kardozy has same opinion as this.

When I was using a 250w Panel max I got was 34v so I think you should be fine with 4S3P but 3S4P is certainly safer incase your Panel voc is higher than mine.

Edit: I guess we were all posting simultaneously, lots of support in this thread.
