That can you said about this inverter

They work as expected..

Overall pack performance is not determined by Grade A cells alone.

There are a lot of factors that make a high-performance Battery pack.

abuzz33:


Most lifepo4 batteries in the Nigerian market are not grade A and those that are are very expensive. Powmr has a history of fudging numbers and poor quality. I take their 6,000 cycles with a grain of salt.

As for lifepo4 it's a superior and more flexible technology for lots of applications. But basic stuff lead acid is perfectly ok.

I use both and this was the second set of luminous batteries I bought. The inverlast battery I used for 5 years and it was still as strong as ever. Luminous is a great rugged brand and testament to this is the fact that schneider bought them out.

1. Don't be quick to generalize this.
2. Basic stuff is what clients will say they want until they start abusing the pack, and many marketers are not helping.
3. 5 years and running means you have the adequate know-how and proper size and take all the measures the lead acid today is not the same quality as 5 years ago.

I am not sure you will continue with lead acid if you need to change the batteries in future.

addition: It is not POWmr claiming 6000 Cycles, they don't make cells.
see below the claims from REPT manufacturer of the Cells POWMr used.

You didn't get me well.
Bms types optional, not bms optional. Bsms Bluetooth and without; 100A bms on a 100a battery is a waste to me.
There is a short length original flat copper not up to 50cm sold for close to 10k. I don't generalize I say what works and still working for me. I love alternatives rather than depending on common materials that can be easily faked. But both of us know that 1C is for few seconds. Some won't even smell 0.5C as we all run different loads. Why do most cases have vents? My solar panel cables is not the regular cable everyone goes for...well, thats private. It handles close to 30a without warning up. I am not the conventional person I go for unconventional materials that work. Lastly, this forum is for those with common sense - you pick, discard, use or reuse information online. Life no suppose hard.

Alright boss, now readers have full gist..

Interesting. What about the efficiency? Does it give close to 7.1kwh? That is what made me to just buy bluetti, because I will be sure of the capacity. I have a locally made power station but I don't even get half of the rated capacity.

The one I am testing has full capacity!

what is the performance and durability of sako inverters? and where can i purchase them in lagos

Durability time will tell, they have 3 years warranty and support is available from the factory, as well as local support.
We managed to set up communication between the 6.2KW inverter and the 5KWH.
The Inverter can now read the correct SOC from the batteries.

Mrreed:
Its another brand, I just used it for illustration. I didn't want to conclude that it's from the Chinese because some of our importers have a thing for over rating the capacity of inverters. Screenshot below is from techfine sales rep

Research is not hard nowadays, nothing is hidden anymore!

Obnoxious2001:


Naim una dey call low cost
God Abeg oh

Pylon 5KWH cost 2M already. and installation cost no be 500K

TechGeek777:


Did you edit your write-up you wrote 52% ?

Yes. seen it 62%. and there is a reason! I will share more insight on the video.

TechGeek777:


I don't know why Chinese love to lie about specs.

If 3484w is 62% of this Sako 6.2kw Inverter, it therefore means that the Total capacity of the inverter is (3484w * 100% / 62 = 5.62) 5.62kw and not 6.2k as claimed.

Thank goodness am not expecting to load it more than 82% (4.6kw) of it total real capacity.

Nice setup though.

I have an upcoming video to explain all these!
too many discoveries, Videos shot no time to edit yet.

The client enjoyed his set for about 2 months and requested an upgrade!
We sourced the product with the client while choosing low-cost and efficient products, from Panels to inverters and batteries in a transparent manner. Installation was carried out, and the client did the load test, showing that he can now power all his 2 regular 1HP Hisense ACs, a Refrigerator, and a Pumping Machine without waiting for the Grid. Video coming soon on my YouTube channel.

5 X 570W High-efficiency panels. (780K)
6.2KW inverter (450K)
5KWH (1.25M)
The total package is under 3M Naira.

we count 1 before 2.

Edrizz:



For clarity n learning sake, this capacity test defiled what isangjohnson said in one of his posts that the real capacity test n the true battery capacity exist within the green range of 3.0v (12.0) - 3.4v(13.6)


So please help someone elaborate

I am making another interesting video, you will love it!

So felicity has high voltage batteries and inverters... Why are they not in the Nigerian market..

It is about Demand, HV inverters are industrial applications. its has not become mainstream like that. Once demand increase they will surely bring them, you can always ship it anyway.

jonescosmos:
Inside Felicity FLA48500 25KW

This Build quality is top Notch, Flexible Busbars, Compression plates, Protection films, and Fuses, But some folks will still say rubbish about Felicity packs without any evidence.

Weldone Boss! Great Job!

1. Honestly I have no idea.
2. Sunshine solar panel
3. The battery has 6 LED lights to indicate SOC (see picture) according to the manual but since I got it, all the lights have stayed on even when I'm using the battery to power the load. all the lights just stay on which is quite weird. I suspect that probably because the BMS has not been configured, so the lights are not able to show the state of charge correctly. So I have been relying on the inverter panel to read the battery voltage.
4. I used an installer.

3. this means you need to start from the batteries, as Marstek promised to send down a technician, then wait for them.

4. Also contact the installer to explain how the panel was configured.

Nutridelfarms:
Hello Guys,
I just installed a 6kva inverter system. The inverter brand is Gospower (6kva) while the battery brand is Marstek (5120Wh). This combination was recommended to me by someone. It's been up to 3 weeks since I installed this system and I am not yet impressed. The first issue I have observed is that I hardly get up to half of the total power output of the solar panels (10 x 330W). I understand it's cloudy but the few times the sun has shone bright, the maximum output is usually around 400-500W.

Second issue: I observed an anomaly yesterday when power went off. I observed that the voltage on the inverter panel dropped drastically to 48V from like 54-55V upon disconnecting from the power grid. This was shocking to me. Then shortly after that like 5 mins, the voltage dropped further to 47V which triggered the inverter to shut down. I had set a low DC voltage of 47V. My load consumption is very small - ranges from 200W to 400W. 400W during the day when the industrial fan is on. All other appliances are basic.

My next course of action was reaching out to someone to come do an independent troubleshooting and inspection as I can't tell where the fault is coming from: inverter, battery or the installation. Secondly, I contacted the battery manufacturer to complain about the issue and they promised to send a technician over.

I'm still in shock as regards what might have caused this issue.

First Pic was taken shortly after power went off showing the drastic drop in voltage.
Second pick was taken upon restoration of power in about 10 mins when it first went off. As you can see, the battery charge status shows a fully charged battery and voltage rose back to somewhere between the float and bulk voltage.

How was the Panel connected?
Panel Brand and specs?
Do the Batteries have Monitoring showing SOC, Voltage?
and did you Install it by yourself?

In case

Good evening senior men,
I have 6kw growatt and I'm trying to understand the mppt
The maximum volt is 500
Is the 500vdc limited to each string or both strings on the inverter?
For example, 330v for pv1 string and 330v for pv2 string or 330v shared among both strings?

It has 2 independent trackers 500V each and is limited by 16A input current.

MPPT Solar Charging Mode
Max. PV Array Power 4000W+4000W
Max. PV Input Current 16A+16A
Start-up Voltage 150Vdc±10Vdc
PV Array MPPT Voltage Range 120Vdc~450Vdc
Max. PV Array Open Circuit Voltage 500Vdc

I've attached the photos.

It might be the weather very cloudy today

I noticed it some days ago too when my battery was full but once I put load on it it started charging again so was confused seeing it today weather is dull.



It's really cloudy today though.

Zero Current from PV is interesting.
