What do the experts think about the illuminous inverters and batteries? The batteries are kind of slimmer and higher than the once i have been seeing here.

Enjoyed it for just about 3months,then i noticed the charging light was just blinking instead of staying on whenever light was restored. It was no longer charging, the local supplier came around and then sent it to lagos.
I hear the panel needs replacement! Been so so disappointed.

Please Guru's : are ILLUMINOUS products reliable??

Luminous i know, illuminous, never heard of.

coderXO:


Yes I know these, however I don't think 1000W can handle the startup surge needed for a refrigerator.

What is the crest or surge factor of your inverter

So sorry, LUMINOUS.... was probably thinking of something else.

please gurus in the house,help.We just Inatallwd an Inverter with 2solar panel and two batteris last week.Unfortunately,the back up time doesn't last long ,maximum of 30min.The inverter is a 2.4kva and the batteries,one is 200Ah and the second is 100Ah.These batteries are not even charging with the solar.We have been using gen and phcn to charge them.Even if u charge through out the night,we still get the same result.After calling the istaller for sevwral days,he just came to rectify the solar,that we will still need at least two more solar panel to caarge the batteries.Im already fed up.

It is generally not a good idea to mix batteries of different sizes, I would recommend that you use either two 100ah OR two 200ah Deep Cycle batteries

With regards to solar panels for two 100ah batteries i would recommend Monocrystalline solar panels totaling 400 watts or more and for 200ah batteries Monocrystalline solar panels totaling 800 watts or more

You have made some very good points. I was just feeling like my innocent post about a N10,000 Inverter was taken out of context. For examples of what I was trying to elucidate you can view the following links:

learn.eartheasy.com/2012/07/our-simple-diy-home-solar-power-system/

youtube.com/watch?v=9gnODiZqrVU

I recommend the Mercury 2.4 Inverter, because I am personally using it at home and I consider it to be one of the best investments I have ever made. It is an absolute bargain and amazing value for money.

I bought this 2.4 kva mecury inverter but yet to get a battery, I connected it to a wall socket but there was no sign on its digital display nothing to show that the device is on. Is this normal or could it be the device is faulty. Urgent response is needed as I have just few days option to return this device

I'm zero when it comes to knowing the technicalities and language imvolved in inverters, batteries, solar etc.

I've inverter, 4 batteries, and solar panels (6) installed here in Kano.
I thought the job of the solar is to charge the batteries same way as Nepa would. But for me, it never works. Only charges with gen or nepa.

I thought as long as I've good sunlight then I'm sure of light during the day. But nothing

What could be d problem with the solar-inverter system?

For ur info, I'm in kano. The sun here is similar to the fire in hell.

Were you able to solve your problem?

Hi Lozenge,

It is normal, the Inverter needs to be connected to two 12v batteries in series inorder to generate the required 24v. You can find the Installation manual which explains all at mercurydirect.com.ng/blogs/mercury-inverters/58851973-mercury-inverter-user-manual you have bought an excellent Inverter which will give you many years of loyal service.

I don't want to rub salt on an open wound. You got exactly what you paid for. You are asking people who you should have paid money for a professional installation to correct a problem someone else created.
1. The battery issue has been addressed
2. What capacity panels do you have. How many watts?
3. What charge controller do you have?
4. What capacity charger does your inverter have?
5. What is your usage?

I don't need to know where you stay. Ignorance is not an excuse. You are spending the money you should have done some research. Do you go to a foot doctor and decide to get heart surgery? You don't. A CCTV is not a solar power person.

I am not being rude I am being factual. You are asking people who know to give you free advice. Some humble pie will come with it.
No charge controller? The batteries will be drained by your panels on low or no light conditions. How will the charge be managed to your batteries? Your usage is moderate. You need to invest in a controller. Ask the guy what size panels he installed for you.
Plan to spend money and have a professional correct the crappy / shi**y work that was done by your installer.

The guy is not only not a professional, he is a dangerous criminal. You need to take the advice given by Chris and get a real professional in ASAP. It is essential that you do this so you don’t lose the money you have invested and more importantly to ensure you and family are not in any danger.

Thanks for your advice. I will try ask around if I can get someone else to fix it.It's just that I don't know where to get someone here.May be I should call the Installer to Uninstall the panel before my roof will blow up.Truly,I'm not happy about this situation.We got his contact from Vconnet online earlier this year when we wanted to install the cctv.Since then he has been disturbing us to install the solar and the inverter.He has been bragging that he has installed for several people.we just had to give it a go since light is not really stable here.Concerning the charge controller ,I told him about it but he refused that the connection is o.k.He has managed to convince my hubby that installing more panel is the solution.How to even persuade hubby now that the guy's work is not good is going to be my challenge now.Thanks

Before all of you start making claims and charges perhaps you might ask the lady what appliances they are running and other related factors within their home.

This so-called professional is not a far cry from anyone else here who claims to be a professional.

This ain't rocket science please.

Charge controller might not be their problem however we all know that it is needed to prevent overcharging.

With what they currently have, I doubt their panels are anything that will actually eventually overcharge the batteries.

I will assume they don't even have a total of 300W altogether if they guy told them they need two more panels.

Then again, it was mentioned that they use the generator to charge overnight as well.

Augustbreak, how many panels where installed? What is the inverted brand / model? What is the brand of the batteries? Can you tell if the batteries are new?


Have you made sure there are no "heat/cooling" producing appliances turned on that could be draining your batteries?

Thanks.There are two panels Installed but I don't know their capacity.The inverter is a 2.4kva Mercury inverter and the batteries he just brought them and installed in a box.They are of different sizes and make.We don't use any heat or cooling stuffs ,so far the TV is the main appliance we have used before drainage.Thanks.

I think Augustbreak should be given a break.

He or she has no idea about the solar system before asking someone with no proven intergrity to supply and install a solar backup system. Chris, i think you are too hard on him/her who admitted to not knowing.

Augustbreak, i think you've been duped!

Its really complicated but i will try to point loop holes in your system.

1. Your system backs up for 30mins only on the load you listed, that means you battery is dead on arrival! OR

2. The inverter charger is either faulty or inadequate.

3. It is wrong to install 2 batteries of different capacities and probably different brand or type to the same system especially in series which am almost sure its ur case with a 2.4kva certainly 24v.

4. Solar panels can charge batteries but may fry it with high current or voltage or over charging. Charge controller prevents overcharging, controls the charging current and voltage so as to protect the battery from damage. A 12v solar panel produces 17-21v to charge a 12v battery which requires 13.6v to charge. Directly means the battery is geting high voltage. Charge controller has a DC voltage regulator to givethe battery only what it needs. In same vein, a solar panel may produce as much current as required to charge but when charge is full that high current will damage the battery when the controller would have lowered the current or stopped charging entirely. Your, battery may have been fried already depending on the capacity of the solar panels.

We have little details on your system but not minding the details, your installer is far from being honest. I dont know how much you paid for the system and the state of your batteries since they are most expensive of the lot with the highest dependance. My guess is the batteries are not new. You can only get a better installer if you are sure the batteries are good but if not, just get your money back or dump the system till you can afford new matching batteries and charge controller. 30mins backup is too poor for at least 6hrs of charge.

Hello Guys, Is it possible for me to use Inverter with my Fridge Freezer, 3 bulbs and 3 fans?, Like how many Kva  inverter plus battery will i need. Thanks

It is not advisable to run fridge/freezer on inverters but I have a friend who does. 3 KVA inverter with 4 batteries. Also know that you cannot run it for an extended time. Get a big Gen to support it.

I'm not a prof when it comes to this but with the little science knowledge I was able to install my inverter myself. Now my next deal is to get a solar panel and charge controllers. Though I have 2 bps 150ah batteries, I discover that one of the batteries is not too good. I bought a 12V 1.5KVA Xantra inverter. Here is my connection bellow.
Note: I did this to control the change over myself cos I don't want to tamper with the EDB of my apartment.

I'm currently running it on a single battery. For now. Would love to know more about how to calculate my load on it. Cos after putting on everything I normally put on the inverter shows 31%load and the battery drops to 77%. With this I want to know how long it will take me on the inverter with one battery. This is my load list.
1. 2 30W energy lights
2. 4 15W energy lights
3. 2 ceiling fans
4. 42" LED TV about 150W
5. GoTV
Others includes mobile accessories.

Would also want to know if it is more economical cos I use prepaid meter.

I love that inverter even though i have never used it. It seems well built as per quality and data sheet. I am particularly thrilled with the inbuilt AVR, power factor, wall mount ability, display etc.

The downside is that since a switch between UPS or Inverter mode isnt mention coupled with the fact that the data sheet only mentioned 150-280v operating range, i am scared. In my area, we do have low voltage supply on grid so it will be bad if the above is only applicable. Right now my inverter with inverter mode range of 90-280v is struggling to charge since saturday night when our supply voltage dropped below 90v.

Power factor is 9.5-1 avcording to the datat sheet so 0.9 can be assumed very save. It means you can power your inverter to 1.35kilowatts. I wouldnt go beyond 1000watts. Besides, i will lose hours of backup with more load. If ever you need to run fridge, start generator.

With 75A charger, thats very suitable for very fast charging of 2 batteries. 75A can even do 3 batteries well.

A few years ago I was in your shoes. If is unfortunate that there are charlatans everywhere, more so when it involves a "new technology". I can testify that inverter+ solar is good BUT you must be ready to do some homework. When my inverter system caught fire twice, I abandoned it as a lost cause! A friend eventually pointed to this thread on Nairaland https://www.nairaland.com/390522/solar-energy-complement-fta and adviced me strongly to find time and read from page 1to the end and not be tempted to jump to the end. I will support your decision to disconect the system awhile but please do not let it end there! Now i have power in my house 24/7 and i am not connected to NEPA.I am fully on SOLAR. Your installer is either naive, stupid or dubious to keep ascertaining that your system does not need a charge controller. It is like saying a car does not need a BRAKE because you were not planning to speed. Kindly convince your hubby to join you in this solar study expedition and you will never regret it! All the best!!!!

It is like saying a car does not need a BRAKE because you were not planning to speed. Kindly convince your hubby to join you in this solar study expedition and you will never regret it! All the best!!!!

Thanks a lot.I'll read the mentioned thread.
