That means the inverter can have up to 50A from the solar charge controller.

You can combine solar panels but the resultant wattage, voltage and amperage will be that of the solar panel with lesser value.

You can use Monocrystalline and Polycrystalline solar panels together but you optimize them, please use an MPPT solar charge controller.

Kdude:
Maximum current charge is 50A on the inverter and the charge controller is also 50A.

About increasing the panel:
Can two different wattage be used at same time in parallel.
Example: 150w and 250w
250w and 200w

Can mono and poly panels be used together as well.

Are you the same person as xij38580:?

@ SolnergyPower, which of the following devices can be viewed virtually or better still which way do u think a solar setup or inverter parameters can be viewed virtually.
Thanks and impatiently waiting for ur response.

Circuit breaker (4k each)
Epever MPPT solar charge controller (35k)
Kilowatt-Hour Energy Meter (5k)

the charging and discharge rate, watts stored, battery level, these are the functions of the solar charge controller. It is then your duty to get a solar charge controller that you can monitor via the internet!

switch time from NEPA to solar. I know of a device that can do this, though locally fabricated.

emmaniche:
Good evening house, I’m new into green energy. But I’ve been mandated to make a quotation for the installation of solar energy at a particular location.
My main concern is the client in concern is really interested in monitoring the solar setup over cctv and if possible controlling the setup. i.e the charging and discharge rate, watts stored, battery level, switch time from NEPA to solar.
House is this really possible as I’ve been mandated to research into this and give back a quotation for the projected to be kick started.
Thanks very much awaiting feedback from u guys. God Bless.

Are your items still available?

xij38580:
Around June last year, i tried getting my renewable system up and running but with the crazy exchange rate I had to abandon it. I have the following items for sale that I've not been able to use

1)iCell 12V 1.5KVA Inverter (80k)
2)Two 200W CSUN solar panels(60k)
3)Circuit breaker (4k each)
4)Epever MPPT solar charge controller (35k)
5)Kilowatt-Hour Energy Meter (5k)

a. Were the panels connected in series or parallel?
b. Did you use PWM or MPPT solar charge controller?
c. What is the voltage from the solar panels?

b2212:
I used 16mm flex cables all through. and the panels are flat on my roof. what is the ideal charge current for my type of installation.
Thanks for the responses

I have a 250W solar panel specification image attached to this post. Your specification should be within that range.

Since your inverter is 24V, your panels should have been connected in parallel thereby increasing your resultant charge current by a factor of 4.

There are factors that may be responsible for your low charge current of 11A at peak period.

a. The size of the cable that you used in connecting the solar panels to the charge controller. This must be a flex DC cable and should be at least 6mm. 10mm is better. The same size of cable that you used in connecting from the panels to the charge controller should be the same that is used to connect from the charge controller to the batteries terminals.
b. The orientation of your solar panels. The panels should directly face the sun at about 1:30pm.
c. Connecting the panels properly ie the panels should be connected in parallel in this case to have a higher charge current (amperage)

b2212:
thanks for the response. unfortunately i carelessly did not take a picture and it has now been installed on the roof.

i know it is 250W. on my solar controller when the sun is bright i have seen charge current as high as 11a.

what If i connect the output of to my inverter using a 2 output switch ?

b2212:
Great post here. I recently got 4 250w mono panels for my 24V, 1500VA inverter with 4 160ah batteries pics attached.
1. Hw long will it take to get a full charge
2. Can I connect anything to the load output on the controller

Please drop your email and phone number for quicker reach.

What's your location?

GeorgeD1:
only a few pcs remaining.
almost gone!

1. I need to see the voltage and charge current (amperage) of the solar panel as shown in the attached picture.
2. You can load the output of the charge controller, but remember that, the output of the charge controller is only Direct Current (VDC).

Of course consideration is given to the solar charge controller while assembling your solar array, that is basic but there is such a thing called Over-sizing of Solar Arrays.

There are several disadvantages of Over-sizing your Solar Arrays. Some are...

a. Components age faster. When inverters are loaded are more than their ratings, this can lead to overheating and shorter life-span of the components in the system.

b. Lower Efficiency. Over-sized arrays usually have higher VDC.

c. Power Clipping and Generation Loss. Let's take for instance, if you have an inverter of 10KW and your solar panels are capable of producing 15KWp. In such condition, at peak periods, the panels should be able to produce 12KW of power. However the inverter will only be able to process 10 kVA and 2kW/ 2kVA will be lost or clipped.

d. Waste of resources. The excess panels plus other resources used to remarkably over-size the solar array will be waste of funds, time and other resources.

harveyspec:
are u sure u aren't making a mistake? what he should be considering when adding panels should be the maximum amp rating of the charge controller & not that of the inverter

if the charging current of my inverter is 12a max, are u saying i should limit what I get from the panels to 12a?

It is usually written on the body of the inverter. Though you can also find it in the displayed parameters in the inverter if your inverter has a display screen.

Kdude:
Please which one is "maximum charge current of the inverter" ...because logically more panels more current (A) and lesser time for battery to get fully charged.

If the maximum charge current at peak period is 5.4A, that means you are not optimizing the harvest from the solar panels. Please check for the following...

a. Size of the cable. This should be at least 6mm flex cable, 10mm is ideal.
b. Alignment of the panels to sun rays. To manually do this, stand under the sun at about 1pm, let the "panels' back" face the side that your shadow falls.

On other questions:
1. More panels will give earlier charge time but please put into consideration of the maximum charge current of the inverter.
2. No. If your battery is discharging without load, the battery is very likely bad. Though, in some cases, the panels can give the battery a boost during sunny time but as soon as charge current from the panels fluctuates, the charge controller may drop a bar from battery indicator in the charge controller.
3. Yes sir. You can simultaneously charge the batteries with AC current. But I will advise you against that if your panels are charging the batteries enough.

Kdude:
Thank you.

The peak I ever noticed on charge control has been 5.1 to 5.4 thereabout.

1. Will addition of two more panels give a lasting result?

2. Did you mean that the discharge I'm seeing is the excess of the 24v?

3. Can still connect my inverter to electricity at the same time?

I am going to answer your questions based on assumptions using near ideal situations using the specification of solar panel that you uploaded.

Solar Panel Specification

Wattage: 200W
Voltage: 36.6V
Charge Current: 5.46A

When you connect your two solar panels in parallel, you will have

Voltage: 36.6V. The Solar Charge Controller will take only 24V from here....
Charge Current: 10.94A (5.46A x 2)

Battery Bank

Your two units of 210Ah, 12V in series will give you

210Ah, 24V.

Expected Charge Time when the two batteries are fully depleted will be...

Time to Charge = Battery Ah[b] /[/b] Charge Current

T = Ah / A

T = 210Ah / 10.94

T = 19.27h

So your batteries will be expected to get fully charged in 19.26 hours if the two batteries of 210Ah were fully depleted.

Thank you.

Kdude:
Thank you.

See the first picture

Second picture shows the state this morning after depleting the battery last night. It doesn't show battery discharging but after like 1 hour of sunlight this mng it starts to discharge.

Kdude:
Thank you for the info:
The picture attached may stress my question.

I have 2.5kva 24v inverter with two pieces of 210ah battery connected in series making 24v.
I intend running off grid with solar panel 200w with charge controller pmw 50A.

At first, I got one panel 200w connected and indication on charge control was normal (first picture) but the battery was not or never fully charged.
I got the second panel 200w attached connected in parallel and now the indication on the charge controller shows battery discharging despite the inverter still off(second picture).

1. What am I getting wrong?
I don't want to talk about appliances now because I intend getting the battery fully charged during the day.

2. Which part of these ports is used to charge the battery using electricity, supply to the house already done? What does the generator mode enabled or disabled mean on the inverter.

Thank you.

What is the charge current as shown in your Charge Controller now 01:32pm?

Kdude:
Thank you.

amarilo:
Hello Pls I need to buy solar panels, inverter and battery for my house in Nigeria. I am in Germany now and want to buy the small small so that I can get all before my coming back. Pls can you direct me on what to buy and their voltage, wattage and any other thing, I tend to power 4 room, 2 sitting room, two TV's, pumping machine and washing machine.

Thanks

Please check the back of the solar panels and to see a similar image attached to the post, snap it and post here.

We take your questions from there.

Please be more explicit in your request. I cannot decipher what you mean.

Kdude:
DIY; Kindly guide me to the ac output on this solar inverter ...

What is the voltage of your inverter?

By the way, one 100w solar panel won't be able to charge the 100Ah battery effectively within a day.

Lionmarshal:
I decided to start with a lower solar system to enable me power my 2 fan and 1 laptop ,a led tv, and like 3 bulbs max.... so from tutorial I watched
100watts panel
100ahms deep cycle battery
1000watts inverter
Charge controller size wasn't given in the tutorial ... so according to my plan, I want to use this a a start then later I might add like more panels that's is 100watts x3
And I wish to use a bigger controller at start so that later when adding the panels that same controller can still go on with the installation not required to replace..
So I need your urgent guidelines for me to set this up.. I also learned the solar system 8yrs back but didn't put into practice so I have almost forgotten everything.. need to set up this week to next week

Yes you can. Though judging from your question, you may need more clarification to set up your system if you are the one installation. May I know your intended configuration?

Lionmarshal:
Hello... I would love to buy some components from you if you are close to Lagos ... and can I possibly use a 30amps charge controller for a 100watts panel and 100ahms battery? I need an urgent response as we need to buy those items this week.
I think of a higher controller should incase I decided to add more panels so that the same controller can still carry on with those panels ... so I need your advice

Sir, I said 2x250W, that means 2 units of 250W solar panel.

perloomey:
250w solar panel is not enough to charge a 200ah adequately
let's do some mathematics
a battery is 12v 200ah= 2400wh
the battery can only give u 80% of it's life span which is 80% of 2400=1920wh
in Ibadan we've 4hours of good sun
so divide 1920/4= 480w
if u use 250w it will take close to 8hrs to charge a battery full
for more information contact me on 08068783141

Yes.

The terminals coming from the solar charge controller will terminate(+ve, -ve) at the same point on the battery terminal heads(+ve, -ve) as the those terminals(+ve, -ve) coming from the inverter.

kenocom:
Please is it possible for my inverter battery to have two charging source? i.e public power and solar power.

If yes, do you have any pictorial representation on how the connection will look like?

Cool ride.

What your brother has is the standard inverter and what your brother needs are...

a. Solar Panels
b. Solar Charge Controller
c. DC Cables
d. Circuit Breakers

As shown image below, when the solar panel traps charges from the sun, it passes the energy through the solar charge controller to the batteries for the batteries to charge.

The solar charge controller regulates how the battery is charged effectively.

There is a hybrid inverter, this type of inverter has an inbuilt solar charge controller. So in this case, the solar panels are connected straight into the inverter.

eraly:
And pls, is solar panel "inverter" different frm d normal regular "inverter" or one can use d regular inverter for/wit d solar panel?


Y am asking is because I wanna convince my bro to do solar inverter(though he has d normal regular inverter. 5kva + 4 200ah batteries) but he thinks he might need to buy anoda different inverter for d solar setup. I am not sure abt it n dats y am asking.


Thanks

veekid:
I think you know better with the way you sound. Like how much will it cost to set up one for a sef contain apartment?

I quite understand what you mean. We also take that into consideration while installing.

But with your description, the inverter is still exposed. The breaker ought to be between the load and the inverter.

NoMoreTrolling:
There is always an engineering solution to everything.

My cousin provides inverter setup in each of the new houses he constructs and the electrical engineer simply wires a fuse/breaker from the battery to the inverter to limit current draw.

So if a client decides for instance to run a 1200watt iron on a 1.5kva inverter, the breaker would simply open up and shut the system down.

If time is on your side, please tell us the exact issue(s) you've with solar power. This will educate quite a number of us.

darknetcom:
me??..solar...

kiiii.. ..

bwahahahahaha...,,...

good one....ohhh my..

We've enough land to go around. Please don't forget, this will also create jobs.

On a lighter note, I admire your disdain for solar power...but I'm sure you'll also be a good crusader for same as soon as you're convinced.

darknetcom:
this things need space..you would cover the ol place for panels instead of farms...

its a rubbish idea
....

forget all those sissy wuse greenpeace rubbish europeans..
...

do you want to catch up or not


....

Heavy industrialisation will require what is called a solar farm. That's a multi-billion project.

Please be reminded that there are smaller solar farms already running in Nigeria, most of those ones are targeted at rural areas and villages.

It may take time, but as soon as we start manufacturing the solar components, it'll be readily affordable.

darknetcom:
very low output..

forget heavy industrialization with only solar..

solar is not an option for a nation of 180million....

for small nations of 5million its possible...

but for nigeria its a very bad idea...

one panel for 70000naira..calculate how many you would need..
only the panels is useless..the sun dont shine everytime...you need batteries to store energie too..

costs will explode..solar fridge..solar frying pan..solar iron..

with which money??

1KVA Cost.

*Inverter installation only*: ₦200k - ₦250k

*Inverter and Solar Panels Installation*: ₦380k - ₦450k.

Can you post something here -an estimate using certain scenarios- so everyone can benefit? That way, you'll show your expertise and prove that you actually know your stuff. That's how you get more business. Education before asking for the sale

We've been powering a pumping machine for a farm and the farm house for almost 6 months now and the solar components are still very optimal.

It's 3.5KVA inverter, 2 batteries, two solar charge controllers and 8 solar panels.
