Growatt inverters consume too much power o. Is your load that plent? If your load is not up to 2000W, buying the growatt will 1. Be a waste of Money 2. Growatt 3kw inverter is said to use 50W on its own on stanby. That is a lot of power that the inverter will be consuming on its own. But since your system is a 48V system, I dont think you will see any 48V inverter lesser than 2.5Kw upwards but bear in my mind that it consumes a lot ot power. Many youtube videos testify to that

Please share the exact model no. of the growatt that consumes 50W, is it also a transformer type?

get this small portable 28ah LifePo4 power bank at a very pocket friendly price of just 50k and thank me later. This can power your laptop for straight 10hrs non stop. U can also charge your phone as it has an accessory for that. I built this packs using mtn lumos LifePo4 cells. Chat me on WhatsApp for more information 08034694579.

LiFePO4 or Li-ion?

luvablesam:
I need some advice:

So I have a 40AH LIthium battery, a 150watt panel and a 30A PWM charge controller.

Is it safe to charge the battery with the panel and chargevcontroller permanently?

Are you sure the PWM's voltage and charging parameters are fit for the lithium?

Trueigbo:
Please someone assist me

It looks like it is.
Do you feel it isn't?

Olarewajub:
Hello everyone!

I need recommendations for a rechargeable standing fan with the lowest wattage possible.

most of them have similar consumption.

bobmalu83:
Good evening my profs in the House.
Please, a client have a following setup.
1. 5pcs of felicity 10kva Hybrid inverter connected in 3phase. 20kva, 20kva & 10kva
2. 5pcs of old version of 15kwh Felicity Lithium batteries.
3. 80pcs of 300w

Now, the inverter is not charging well even with the constant NEPA light that is connected with the inverter once there is an outage the inverter won't last long and the batteries will run down. While the 10kva inverter being the 3p is on constantly displaying error 14 in front of the screen and the grid icon flashes continuesly without mercy.

My question is, what may be the problem and the possible solution.
Note, the set-up is not up to 5 months. Thanks in anticipation

What does error 14 refer to in felicity's documentation?

Rubyjade:
How many Kva?

5kVA with lithium battery

brightk:
quite understandable. i need your ideas on this... Assuming i have a hybrid inverter whose maximum mppt input it 4kw and i oversize my panels to 7 kilowatt incase of cloudy days.. Does it mean that my hybrid inverter will clip the power to 4kw only during sunny days?

It may not make sense putting such amount of excess in one place, you may stress the device. You can put the excess on a charge controller or you double the inverter if you have the means.

excanny:
Hello, I need reviews from users. Any one actually used a brand new Monbat inverter batteries for 10 years as claimed or it's just marketing hypes, before I break my kolo to blow 285,000 naira away?

Solar enthusiasts and engineers abeg show me road o. I never follow this one before

If you want 10 years, try lithium, LiFePO4.

Off I went to the Market today to see if we would be able to arrange an inverter for the house.
I only told my husband, whatever we settle for must be able to carry our freezer.
My husband is an electrical engineer so he designed the power requirements of the house so we have an idea of what we were searching for.
Budget 1.3m tops.
We settled for a store we saw on Jiji with reasonable price, called to find out if the store was open since it's sallah and located the store.
We were able to get the following.
4kva/48v microtec inverter ₦290,000
4 nos 220ah/12v lotion battery @₦160,000 each making ₦640,000
6 250w Canadian fairly used panels @₦58,000 each making ₦348,000
1 60S mppt charge controller Felicity ₦115,000
Battery rack ₦20,000
20m 6mm DC cable 40,000
Total spent ₦1,453,000.
Transport 14,000 to my house .
Tomorrow the installer will be around to start installation.
We negotiated 50,000 workmanship.
He will come with panel sittings and screws
.I intend to use the inverter on 15 energy saving bulbs.
1 50" tv.
Phone charging.
4 ports.
My 200l freezer inverter freezer/ medium fridge.

The panels aren't sufficient to charge the batteries, except you'll be majorly charging the batteries with the grid, those batteries may fail sooner.

Zico777:
Almost 2m. I believe the price would have gone up as a result of fuel price increase.
U should be more particular about location.

That's correct.
A similar setup we recently installed cost a little above 3m, powers three freezers and other home appliances.

earthrealm:
Nope @ sunfit.
But had with flames and Suntech, they aint in same league with yingli

Ok then.
I think the sources of sunfit and xtrapower aren't too different and they perform moderately well.

mctfopt:
That's almost 3x the cost of PowMr. With that much difference in cost, if it doesn't have more capabilities, then it doesn't make sense to get it.

Simple

Obinnau:
Please experts in the house. Can a 1.5kva inverter system connected to a 200ah battery power a fridge of 130 Watts? When it is just only the fridge that is connected?

Also between tubular battery and felicity gel battery which is better? Or even a better recommendation.

Simple answer - Yes
Try Ritar, I would also mention fullriver but I'm starting to lose confidence.

FEGEITOK:
Homaya Pro M1000 versus Powmr MPPT-60A Charge Controller Solar Review (Specs Only)


Updated to include Powmr MPPT-60A maximum PV withstanding Voltage


Maximum PV withstanding voltage for Powmr is 160 volts but the company itself warns not to run it at that rate for long because it will break the controller.

So I would say that figure is not to be relied upon

At 160 volts maximum PV withstanding voltage, Powmr has better capacity

So you gotta decide the 100 volts PV hard limit of Homaya or the 160 volts PV unreliable hard limit which do you prefer to bank on?

The Powmr beats the Homaya but I understand you're just marketing.

monchazfarms:
Good morning, good people. Please, I need your inputs on the best configuration I can employ to install 16 units of 100w solar panels with a 24v smarten hybrid inverter.

I really need your inputs on this. Kindly help a brother.

Inverter specification: 2.5kva/24v
Maximum panel wattage: 1,500
Maximum pv voltage: 85v
Maximum battery current: 50Amp.

Comfortable config ... 3s5p
Adrenaline config ... 4s4p (you can try this, with some losses due to positioning and wire, you MAY scale through during peak output and favorable conditions )

Obnoxious2001:
Na alaba I dey use oh

We talk them down too much but the funniest thing is many manufacturers want to collaborate with this guy's.
Them get many investors

I wasn't actually demeaning Alaba as a whole, there are authorized distributors and resellers for genuine and reliable products there.

What you should be more worried about is about the system design and not just pricing. If you don't trust the pricing then maybe you're not really confident about his proficiency.

matoseyems:
USE GOOGLE TO CHECK BRO, NO ALLOW ANYONE OVER INFLATE PRICE FOR YOU.

Does Google lists products for sale?

He'll either see prices on websites that have not been updated or see prices of Alaba hustlers that don't actually have the product but would put ridiculously cheap prices to lure him to them at Alaba where they can then give him "oga this one too they work, na im I dey use for my house".

earthrealm:
yingli isnt in same class as sunfit and flames...yingli is far far better!

Do you have an experience with sunfit?

Obnoxious2001:
Accessories,trunking,mcb, logistics and 6mm² are highly inflated.

I would have included the 2.5mm wire but I don't know the distance it would run.

So I put it to you that the creator behind this quotation is after your life

Please state the location let's snr men help you scrutinize.

How much is a mcb ?

JUO:
tell him the price for jinko 400w and see him run away. Check respond above. One said 6mm² at 2k per yard is inflated and he doesn't know distance too, 20k logistics is inflated in alaba. They just sit down and type

I was surprised too, he even said the mcb were overpriced.

Pojomojo:
What's this?

What You See Is What You Get

ojeysky:
Well it also means 95A and below is fine. That said using the recommended 65A that is almost 0.3C. Seem high for a lead acid that wants to last long

That's fullriver DC variant. They're said to have that ability.

brightk:
hello house.. Few articles i have come across suggests that solar panels should face south for optimal energy production. I decided to check on my panel direction using a digital compass on my phone this is what i get.. Does it mean my panels are facing the north? I have been getting poor outputs from a 1.2kw setup.. Althought i was not the one who mounted it.

Today i went to aanother location where the roof position was pointing in a south east direction with panels on it.. i also want to know if this is a good direction also..

I will appreciate all comments from everyone... thanks

Stand with your left hand on the side where the sun rises from, then your right side where the sun sets, your back would be the northern direction while were you're facing is the southern part, this should give you an idea.

emmy9500:
1.Did snap the nameplate, the carton is VIP solar

2. I don’t know how it was connected

3. the installer said it should face where the sun rise

4. Cost per KW

Answer this yourself, if the panels face where the sun rises from, what happens when the sun reaches the zenith, what happens when the sun crosses to the western side?

emmy9500:
Finally installed my solar system, thanks to all the information in this group

I have a question, I have 3 panel rated 380W but my charge controller only read 340-400W the installer said it would have been higher if I used 200W panel, I am planning to add another 380W solar…. I just want to ask if the reading from the charge controller is normal

Why hasn't anyone made a comment about the inverter and battery combination or does that inverter have editable setting or charging profile suitable for lithium?

emmy9500:

ElRazur:
Guys abeg, I need your help and clear advise - preferably from those in the know.

I urgently need to set up 10Kva solar system and I need your advice abeg.

My needs are simple: power 2 inverter AC at least for 24 hours. Lights and TV, occasional water pump use.

I have narrowed things down to using LiFePo4 batteries due to have a longer use life, but picking a reputable brand seem to be a minefield. I'm leaning towards Felicity but I am not even sure anymore due to all I have read about them etc. Please advice.
