27th of last month.. Since then na just one headache or another

I see other gurus are already helping you out. I've got faith in Growatt inverters and believe you probably just need someone experienced to come and double check what your installer did.

I also believe if you've got freetime and can spare a weekend to study the manual, you'll probably be able to set it up to your preference and understand if there is an actual problem or not.

AndroBlaze:


It depends on you and your needs.

The setup referred to consists of a 10kw battery with 5kw pv . Most of the time this is adequate for the power needs of the family 24/7, so really should be entirely off grid. However, sometimes (depending on who comes around for visits, we're always transiting) 2 inverter ACs are run from 7pm to 8am and this takes it toll especially on days where we'd also run the ACs all day and their was poor pv output.

So to avoid the batteries being regularly charged by NEPA, that usually comes at night, rather than solar, the amps for NEPA were severely limited to half what we set as maximum for PV.

So answering your question generally, for best longevity of a lifepo battery 0.2c (or less) is recommended. For a 200amps battery that's 40amps.

So for our setup (I'm currently not around) solar was set to something like 60-80 amps while NEPA was set to 20-40 amps.

Hope this helps.

0.2c where did you get this value for Lifepo4?. That charge rate is too low and not taking advantage of the battery chemistry.. 0.5c is advisable ( 50 percent of battery capacity). I doubt most people here with home solar can get consistent 50 percent of battery capacity from their solar array at any one time. For your 5kw solar set up with 10kw battery, I doubt you will ever see 5kw generation from your array.

HeavenlyBang:


This is worthless, ngl. You need an external charge controller.

How is it worthless?

omonla5:
Good day guys, what combination of Solar can I use effectively with this hybrid inverter

Just a single 555w Jinko will work provided it has built in mppt and your battery is less than 200ah.

Modified:
Didn't see the 24v, thought it was 12v.
You will need external cc.

Read what I wrote S-L-O-W-L-Y....and as for what I am getting from the array, you can check for yourself with the screenshots I posted prior to today.

anybody interested in original BOSCH 700w bifacial pv ?
directly imported from
unit price 150k

Yes, the battery is less than 200ah, it's a 3.8 kva lithium battery. 24V. Will the single jinko which is mostly 12v charge the battery sufficiently.

Is this an ego protection mechanism? Charging at 0.2c does not correlate to longer life expectancy. I told you to post the source of your theory and you reply with S-L-O-W-L-Y. Stop gaslighting.

Yes oo. I want to see pictures too.

Oh thought it was 12v.
So sorry. Get external cc pls.

Hello!
I want to order solar s from fouani. Is there a procedure to follow or its a straightforward add to cart and proceed with payment? I'm asking because i ed some complaints of delay in processing and sending.

That was what I did. Straightforward add to cart.

Delivered within 3 days. I didn't even have to create an

HeavenlyBang:


Maybe the Abuja house is on Band A?

Nope... It's confirmed to be on band B.

It could also be that that nepa meters cheat on us. Why no one thinking this is possible? If meters at filling stations cheat, mtn and other mobile networks cheat on what they call 1gb, why can't NEPA be cheating too. This is Nigeria oh

I got 10 from them in Abuja. I didn't even go to their site. Just called their number, they continued by writing me on WhatsApp, they sent their bank , I sent transfer and the next day they brought to my house. Na one rude Indian man answer me for phone sha. I for knack am plank with the way him dey answer me

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

None of these. What is the way out then please Bro. Will the cut out fuse interfer with d solar /controller operation if its in place in between them? I am to use a breaker also upstream before the cut out fuse. I just want to know of it will work since no other protection level is available in the building

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? s 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

Good evening. Please I need una help on this. Thanks so much

You can use a circuit breaker and fuse, but you need to install an earthing.

You can buy a long earth rod and drive it to the ground and run a connection from it to your setup

Avoid the cut out fuse

Ok sir. Please can the powmr controller be earthed? Because there is no port for earth. Or which part of the setup would be connected to earth since i am to use a psw sachet inverter. Or doing just normal house earthing is sufficient?

Thanks so much for your response sir.

Hi guys,I am new here,
Read tru the pages,
Well-done guys,

I need quotation for a setup of 2kwh batteries with running power of 1800w+ that can accommodate a surge of close to 2500W

I hope I am getting my terminology right.

Something to just power my 2 bed apartment
Freezer,fridge,50 inches tv,2 ceiling fan,and couple of standing fans

I would appreciate responses,

The news about increment in phcn fee is scary

mctfopt:


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 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).

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??

You can ground the metallic body of the charge controller and the inverter.

You can monitor your Deye inverter online using the Deye app or solarman app but just like most if not all inverters, it has a 5mins delay meaning you get performance Data every 5 mins.

But the solar assistant you get a real time update.

Is this an ego protection mechanism? Charging at 0.2c does not correlate to longer life expectancy. I told you to post the source of your theory and you reply with S-L-O-W-L-Y. Stop gaslighting.

The only person gaslighting and obviously on an Ego trip is you, as you jumped into a discussion that did not involve you and declared with effontery that I was barely getting 5kw from my PV, when I had clearly posted screenshots of my harvest that makes your claims laughable.

Now I asked you to read S-L-OW-L-Y hoping that you would be able to decipher that I was having a discussion with someone I assumed shares the same maker of inverter that I do and that actually, I actually did not answer his question, as I made him understand that setting up the charging parameters for his battery is a personal thing and largely depends on him and his needs.

My post to him clearly stated that we charge slowly on NEPA on purpose, as I prefer the battery charging through PV as the yield I get on PV is more than enough to meet our daily needs usually.

If you had actually read it, you'd understand that our average charging rate is 0.3 - 0.4C daily, which already marks 60%-80 of the PV array.

Also if you had any understanding of the inverter we are discussing about, if by chance my battery was empty and charging at max 80amps, if my load draw is 1kwh (which it is usually less than) and my yield at that time is 5kwh (maxing the array and this is just an example) then the Inverter would still produce 100amps with 80amps going to my battery and 20 amps powering the load in the house.

So having quality hybrid inverters is not just about charging your battery, as daily the inverter tries to balance things and suite my lifestyle, and I ask it to prioritise using the battery as little as possible, run load directly from the pv, which it does, till the night ....and this now conveniently leads to the battle you and only YOU wants to fight by insisting that 0.5c is the best rate to charge a battery and that there is no advantage or extension of life gained by going lower and charging slower.

For those who can read and comprehend, they will notice it was not my opinion I offered when I said "generally 0.2c" and then making it clear in the very next line that is not the parameter I stick to.

But since you are commanding me and clearly not asking me, I cannot offer my own opinion on it to you.

However, I think their is a solution to this ime, conveniently designed for obnoxiously rude people, so I will post it and you can go and fight them.

Unfortunately it seems Nairaland will not allow me to post any more pics, but Chatgpt pretty much said the same thing and I encourage you next time to arm your obnoxiousness with AI so you can start all the silly internet arguments you want to with all the ammunition you need.

Issue with AI you are quoting is that they are telling you what information they find online.

I won't be surprised if part of our conversations here was also accessed so it my not be a yard stick for making conclusions.

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.

Dam5reey1:

It's not my yardstick either.

But me and you know as a general rule, every mainstream battery technology we've come across, benefits from being charged (and discharged) slowly rather than in a rush for obvious reasons mostly connected with temperature and heat.

Also manufactures gain when we replace things not when we use an item for 10-20 years. From phones to laptops, they gain when we have to replace the battery, so they'd usually encourage us to charge our items as fast as possible to increase degradation.

Those who can read between the lines would know the best way to balance things out and charge these batteries. Veering a bit, I'll never forget one of my first lessons on here when I learnt a 10hr 200ah LA battery seniors a 20hr 200ah LA battery.

All I can say is I pity anyone who is using a 3rd life Cworthlike LIFEPO battery and charging (and discharging) at maximum C rates thinking it will last for 10 years because "every Lifepo battery can do so".
