My 1.5HP Panasonic Inverter (will find model later) drops to around 650W.

That's interesting. Panasonic is always a rugged system.

Edrizz:
Gurus in the house, which is better in effective cooling system between Panasonic air conditioner and LG air conditioner and which is better in energy efficiency between d two of d same capacity

LG, I may be biased as I use LG.

Their Dual Inverter model is just so energy efficient.

Maximum cold running wattage <= 1000w for the 1HP version (drops to around 600w when room is cold)

Dehumidifier mode = 230w to 600w (depends on time of day; outdoor temperature)

Fan Mode = 120w

temi4fash:
OK thank you.

The BMS does this on its own or do we have to manually activate this?

If you use the same BMS, JK BMS, with active balance function, you can decide to turn on or off the active balance feature.

temi4fash:
Hello Boss,

Why is one of the battery showing red?

Thank you

Red temporarily indicates the cell with the lowest voltage. This is dynamic and changes as the active balancing is in progress.

I have been using the skyrun fridge for about 5 years now and also been using it with my inverter for over a year now. It consumes around 100w and even when I put it off around 11pm at night, the things in the freezer remain frozen even in the afternoon the next day

Ok. That's cool.

KA24DETT:
This is too much money. You can buy POWMR POW-48140A for around $260 (400k). Voc is around 500v (48v 140amps). I ordered 10 for my project.
Another cheap option is to buy a 5kv felicity hybrid inverter and use it as a charge controller. I believe Voc is around 500v

He asked for a charge controller. If he asked for an inverter the list is as long as the golden gate bridge.

stuffs2002:
Hi gurus in the house,

Please can anyone suggest where I can get a good MPPT charge controller with maximum PV array open circuit voltage of 250VDC or more

Check jiji

KudozInteriors:
Good evening everyone.
Thank you all for the great information being shared here. It means a lot.

Please I need help. I believe most of us here either use inverter freezers or have an idea of it. I want to get either thermocool 219L or Scanfrost 230L inverter freezers but I don’t know which will serve me better. Any user experience from here will be highly appreciated.

Thank you so much🙏🏼

Go with Scanfrost. I have a non inverter 250L Scanfrost freezer that draws a maximum of 160w. Freezer keeps everything frozen all day long after running for 8 hours daily (8am to 4pm)

Trippledots:

FEGEITOK:
This argument seems to have left the forum poorer.

Someone very knowledgeable has completely erased all his contributions to the forum.

It is a net loss and not a gain.

There will always be arguments on here. I try, as much as possible, not to be part of them. I just post what I like and reply to things I like, irrespective of what people decide to say about what I post. This is a microcosm of Nigeria-many people from different walks of life and disciplines are here. Some may go all out to antagonize you. My way of dealing with it is to never react the way the person thinks I would. I do the opposite of what they hope.

We are all here to share knowledge, and differing opinions is often part of it. But I have noticed that most Nigerians cannot counter opinions with mere facts without resorting to personal jabs. Once you’ve been online long enough, you learn to ride that rough wave like a pro surfer.

jonescosmos:
It is what it is bro, there is a gang of people on this thread that are hell bent on reporting you and your post once it goes contrary to their opinions or exposes their false claims.
They did it to me severally and I have decided to be just a reader on this thread after the event of three weeks ago when I posted a link to where people can verify Who is Who in Deye Distributorship Categories. I was banned for three days straight and investigations revealed that my posts were being mass reported.

I have also decided to post adverts when I have any, because it seems that's the only posts that doesn't get reported here. Criticisms and counter opinions lands you in the banning basket.

So if anyone finds him or herself in that situation, please don't take it seriously, don't take it personal. Just move on with more productive activities elsewhere.

Cheers !

I doubt anyone has reported anything. Nairaland's SpamBot is crazy. I noticed it doesn't like too many numbers. Also, you can easily get banned for posting links unless you space them out so they won't be clickable. What I usually do is either take a screenshot of something and post it as an image or post links with spaces in between to avoid triggering the crazy SpamBot

Dam5reey1:
AI and Theories everywhere..
Make una dey try test and show workings.

Never depend on what some inverter display shows. For PV generation.

Tested 2 inverter:
one overstates PV input while the other slightly understate PV input

That one that overstates is the weird one

icjunior:
Thanks so much bro,I noticed a recently fixed standing fan was the culprit. I was so relieved men😁

Thanks for taking your time to reply also.

Oh, that's cool.

icjunior:
Please who uses smarten inverter here,mine just started tripping off with this message "Short circuit,please check wiring" The batteries are fine.


I don't know what that means,but I noticed recently that my appliances would sometimes shock me,off and on happening.

The first thing to do is this:
1) Remove the output wire (the wire from the inverter that powers your house).

2) Check if the short circuit is still present when you power up the inverter.

3) If yes, the inverter needs to be taken to a service center.


4) If no, there is a short circuit somewhere in your load.


5) If a short circuit is present, you can do the following yourself if you have a basic understanding of electrical wiring:

a) Turn off all loads, that is, turn off all sockets, bulbs, etc.

b) Check if there is any burnt-out light bulb still connected to a lamp holder. If yes, remove it, as it might be the source of the short circuit.


c) Check if any of the appliances (loads) are causing the short circuit by going around and turning on each one while you wait to see if the inverter will display a short circuit warning


If step (c) reveals the issue, you've found the culprit.

kristien4:
For example, u mean after buying a Deye inverter, youll still have to spend over 200dollars to enable you monitor online? Same thing growatt does for free with a followcome dongle??

Real time update. Monitoring data always with you even if you are offline - data stored locally in your raspberry pi SD card. If you DIY it's not up to $200.

Anyways if all these perks are not your thing you can always use the inverter's monitoring software.

favouredbymercy:
Good day all
Please is using breaker for solar input enough to protect this controller? I intend to use the normal cut out fuse after breaker, to manually remove when its about to rain. Will this idea work? Panels are in series, so maximum current input cant be higher than 15amps.
Please what is the simplest way to protect the controller from damage and how have you guys using it here been able to protect it for long from damage. Thanks for your reply

Does your building have lightning arrestor? If yes, how about earth? If yes, just use a DC breaker.

HeavenlyBang:
That sounds awful wtf.

With enough PV you'd easily hit that score to get back to business.

BiigTee:
I also noticed that my growatt 6kva inverter using a (cworth 15kwh battery) when the battery reaches the shut off voltage/percentage of 20% and the inverter stops discharging at night.. By morning when the sun comes on and it starts charging the inverter doesn't automatically come back on and it displays error 4

My questions;

Is this normal?? Isnt the inverter supposed to automatically come back on when there is sunlight and it starts charging?

Is there a particular battery percentage it has to reach before it comes back on??


Someone please help!

Usually the inverter won't provide output until the battery charges to a certain percentage (,usually 20 to 30% SOC)..But the inverter will charge the battery via PV but will not provide any AC output voltage unless there's NEPA supply.

Preator:
Can this be used with Gospower? How much is it and where can i get?

You can always buy their product (software or hardware) from their site. One of my earlier screenshots captured it or just google it. Prices is from $59 for software and $169 to $209 for device and software.

I doubt if it can be used as I don't think it's neither Axpert nor Voltronic inverter.

But to be sure you can always contact solar assistant by sending them a mail with your inverter specification and pictures. Especially pictures showing the communication ports.

Email: info @ solar-assistant. io


FYI: Gospower doesn't know what Solar Assistant or HA means (check attached screenshot).

ManAdii:
Have your tested TBB sir?
I'm not sure deye solar assistant can beat theirs

It is not just for Deye but many other types of inverters.

And no, I haven't seen TBB remote monitoring software. I'm more of a DIY person so I like things that can work for many inverters not just one particular type of make.

temi4fash:
PLease how we get to use the Solar Assistant with our Inverter?

Do i need to buy a different module aside the one from Growatt?

1) Raspberry Pi
2) Install Solar Assistant inside Raspberry Pi
3) Buy the software.


Or buy the device (raspberry pi with software) if you no dey like stress/DIY

CuteMaro:
Please guys where is the telegram link to this awesome thread?

If there is one, many will miss out on the fun.

GloryJoyeux:
Hi,

I believe these are not real time figures, most times there is a 5 minutes refresh delay. And sometimes it doesn’t refresh all the figures. So it probably didn’t refresh either the pv or the battery charging figure.

You can try refreshing again in 5 mins, alternatively, you can confirm physically from growatt inverter.

This is why solar assistant has an edge, it provides live monitoring information and not at 5 mins intervals like most inverters do.

I can confirm Solar Assistant's speed and superior real-time edge capabilities compared to other monitoring solutions.

BiigTee:
Who can please tell me why the ppv generated and the charging power are yards apart on this growatt inverter?

Conversion losses + your load = PV generated.

Also I wonder if what you see is in real time. That is your load consumption and battery charging power whether there is no lag.

Dam5reey1:
Funny enough it's SON Label, it's the Chinese Label that carry 280AH

This our SON na prodigal SON

Dam5reey1:
Glad it worked out!!

Knowledge sharing is on our vision..

So here is the Concluding part of the Haisic 4 19WH 12V Capacity test


https://www.youtube.com/watch?v=8cSSjUeU_CE?si=cDppLjQY0bGOsuDq

At best this is a 3.7kwh so the 12v 280ah checks out. The 4kwh on the label is just the typical over inflation of capacity which most Chinese brands love to do.

Still impressed though.

Trippledots:
It's a contactor with 2 normally open and 2 normally close connections. Grid goes to the coil, and also to the normally open contactor input. Inverter output goes to the normally closed input.

The normally open and normally closed outputs are interconnected and goes as the final output

How it works:
When there is power supply, the contactor energizes and closes the normally open contacts sending power out from NEPA.

Once Nepa goes off, contactor is de-activated and swings back to the normally closed position, sending power out from the inverter... I have a surge protector that helps with voltage fluctuations and also my stab has a delay timer that helps the overall function of the contactor.

Thanks for the detailed explanation. Whenever you have time help with a sketch of this connection. Nothing fancy, just a sketch showing these connections. Danke.

Trippledots:
Some relays and contactors accept direct grid voltage and work with it.

I recently rigged up one contactor to use at home (attached) as an ATS, and it works very well.

Cc numericalguy

Please can you share a sketch of this connection with this contactor on how it works as an ATS?

chris81964:
Yes it is. We have been doing this for years.

I like this. Getting the soil wet for lower resistivity is easier with this technique.

Hello Dr Solar, that thing at the centre of the pipe that I'm seeing is it the earth rod?

Using pipe is a cool way of running earth. I even saw one, at one flow station, where the pipe is galvanised steel.

ola12:
Thanks. I'll rather go for a 1kva as I just need something strictly on a budget which'll do the job of supplementing my grid/replace it on off nepa days for powering my laptop+fan.
I was going for this one specifically but no felicity dealer has it in stock, if someone knows why or has used it with reviews please let me know.

If there're other really trusted 1kva 12v hybrid inverters I can get instead I'll appreciate the information

I have none. Try Welion

HeavenlyBang:
The last lead acid 12v 7ah I bought from Jumia didn't even last two months before it stopped powering the fan for up to an hour.

Decided to never buy a lead acid replacement again.

I don't expect this to actually be 9.8aH, but even at 6aH or so I'd be satisfied.

That LA small size battery has horrible lifespan. Especially when you buy off brand. Branded type is often too expensive for an LA battery.
