behind the inverter there are two major outlet input and output
the input is what charges the inverter and u bring the wire from the mains of the house while the output is the one that supplies the house from the Inverter
Buh it better to call a tech to avoid you damaging the inverter

call 08068783141 for more information


Thanks.

I decided to do it the fail proof way.
I plug into input when I want to chare.
Disconnect input and connect output when I want to use it but never the 2 cables at the same time as i didn't want to damage the machine. The installer would stop by one of this ďays.

Cheers.

Op you said car 2 car batteries connected in parallel can also be used. but my question is; how effective are these car batteries?. 2. which name of car battery is d best and how much does it cost?

Never use car batteries for inverter. A friend working with a car battery importer tried it. It was a waste of money, he had to replace them with "inverter" batteries.

Càr batteries are not designed for such un/loading cycles.

car batteries are called ignitions batteries are just meant to ignite a car that is all not to be discharged more than 10-20% whereas the deep cycle batteries are meant to be discharged up to 80% that is why they are been used for inverter

thanks OP. I have an inverter which I built with charger included and I have been using it for sometime now with a motorcycle battery(12v, 7amps). The battery is going bad now. I really have to hussle and get solar panels and deep cycle batteries. If you need inverter(charger included for charging with PHCN) quote me lets talk business.

oh i didnt see that. Then use a frequency converter. In that case you don't need stabilizer if you purchase the right one that converts Voltage and Frequency.

d. Connect Battery to Charge Controller

As stated above, the Charge Controller has positive (+) and negative (-) terminals for the battery, connect positive (+) from the charge controller to the positive for the battery and negative (-) from the charge controller to the negative of the battery.

Ensure that all connections are firm.




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?
Re: How To Install Solar Panels & Inverter For Home-step By Step Guide by SolnergyPower: 10:14pm On Mar 06, 2017
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.

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

Questions are allowed...

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.

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.

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

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?
Re: How To Install Solar Panels & Inverter For Home-step By Step Guide by SolnergyPower: 7:03pm On Apr 14, 2017
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.

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.
Re: How To Install Solar Panels & Inverter For Home-step By Step Guide by SolnergyPower: 6:06pm On Apr 15, 2017
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.

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?

Question:

I suffer more than 12 hours power cut per day, Normal inverters could not get full charge with this severe power cuts,

I want to go for Solar inverter,

My load preference is 1 Fan, 3 CFL’s (compact fluorescent light, energy-saving light) and 1 LCD Tv.

Could you guide me on installing a Solar inverter set up at affordable cost?

Answer:

I Appreciate your interest on solar green energy. Hopefully it will be the future of power back up industry.

For a Limited budget, I could suggest you best possible and cost effective configuration.

I am 100% sure that SOLAR inverter is the only solution for growing power cut problems.

So sit back while I walk you through how to set up a small solar power for your home

Here are the materials we will need to do this set up.

a. Inverter (850VA-1KVA), 12V.......40-45k
b. One 200-250w Solar Panel.....40-60k
c. One 12V 100AH Deep Cycle Battery....30-40k (You may use two car batteries here but must be connected in parallel)
d. 12V,20A Solar Charge Controller....10-15k
e. Battery Stand, you may improvise this.

Total: Between 120k and 160k

Course Outline:
a. Mount your solar panel
b. Connect your charge controller
c. Connect Battery to Inverter
d. Connect Battery to Charge Controller
e. Load your house.

I will provide details shortly about this course.

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
Re: How To Install Solar Panels & Inverter For Home-step By Step Guide by SolnergyPower: 10:53am On Apr 17, 2017
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.

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).
