@MiCasa beware of that thing, don't say you were not warned. unless you have money to throw around. I i'm saying this out of experience

Hi Unionised and DUNKA
We don't discus prices on this thread because of some reasons.
One reason is that this thread is actually a DIY forum and not a market place. We only post our work here to inspire and encourage people in renewable energy. Also we share some of our experiences as part of our humanitarian services to help ppl who want to install solar by themselves to learn.

MiCasa:
Mr. Newbie here. I have read so much from this forum that I consider it my solar-reference-library, albeit I learned a lot especially from the likes of George_D, Richmon74 and others, there are some that I am still confused about. Without wanting to clog the progressive wheel of this forum too much, I need help with a little dilemma that is bugging me.

I have had (almost a year now) Su-Kam 5kva/96v pure sine wave inverter with charging current of 10A to a Saturn battery bank of eight ( 12v200ah connected in series.

While I always wanted hybrid renewable energy with solar array the cost of PV has kept me at bay. Solarpanelstore.com has SolarWorld Sunmodule 275w at $279 (N46,872) plus shipping and that has gotten me seriously thinking to add solar panels to my system.

My concern/confusion are as follows:

1. Are there other sources of lower priced quality solar panels? I will defer to others
Lower quality is not always better. They last a long time get something good

2. How many of the 275w panels (if that’s the best I can get) do I need for my 19,200ah battery bank?
The number of panels you get is

3. How many panels do I connect in a string of series or parallel?
Your connection has to yield 96 V plus 30%

4. Considering that the inverter is 96v, what size, type of Mppt Charge Controller do I need to complement my system?
I will get a minimum of 60 AMPS.

Much appreciated.

dry season is here please gurus wake the thread!

Dry season? Its still rains everyweek in lagos. I doubt if there is anything like dry season anymore.

JUO:
My oga i think the installer used a wrong wire. the wires are too tiny i think...

The inverter was simply running t between 85% to 100% of it's rated capacity.

It was the inverter itself that got burnt not any external component

I stopped by a client's house at Unity road, Lekki today to check the performance of his system and I was impressed by the harvest. This client lives off grid as they are yet to complete transformer installation in that area. The only appliance he is not using are the A/Cs. Every other appliance including Fridge, freezer, washing machine and watter pump runs on the solar system.

The system configuration is:
3060W (12x 255W) Solarworld Solar panels
8x L16 Trojan Flooded batteries
4kw PRAG Inverter.

The 3060w solarworld panels was able to output 3458W as you can see in the picture below which is higher than the rated output of the solar panels. The log also confirmed that this system delivers up to 16kwh of energy daily.

These go a long way to confirm that solarworld solar panels efficiency is second to none. Also remember that the installation must be done professionally also in order to get this efficiency.

Stop littering your roofs with junks in the name of solar panels and also get a profesional installation.

Hello Prof richmon74,

Is this system an off-grid system? If it is, then for a hybrid system, how many panel will you recommend since power from the utility will compensate for charging too(at night).

Good work you are doing here! I ll love to visit you soon.

More grease!

Hello Guys,

I just got a 20kv UPS for next to nothing.

Would you advise i use this at home instead of an inverter?

My energy needs can't be above 2.5kva (and thats if I decide to power my deep freezer, hot plate, pressing iron and washing machine).

A UPS or an Inverter? The Pros and Cons.

And how many hours on full charge can a 20kva UPS carry a load of 2,000 watts?

Advice, anyone?

One off the reasons you have not received attention on this post is that you have not given the complete details of the required specifications. Another reason is that this kind of question is all over Internet so a little Google search would have given you an idea of what you need.


Well, without going into too much details on the technical differences between UPS and INVERTER/Charger design, I'll attempt a response to your post.

An inverter is what you basically need at home though.

UPSs are designed to do basic back up for few minutes to few hours and are not designed to function as a source of power.
- They are not designed for extended run duration on battery like inverters. Most come with inbuilt battery and you cant extend the bank without damaging the charging unit by putting too much demand on it.
- They are not designed to start higher capacity loads (like electric motors, compressors, etc) beyond their rated power as in the case of inverters.
- Their charging current is always very low which is a very serious disadvantage.
- They have very poor efficiency and as such drains battery very fast even if there is no load.
- Lastly, the input voltage range of a UPS is very narrow compared to that of inverters. So if you have a low voltage the ups will switch will inverters will tolerate to a certain extent.

That's how much I can remember for now.

As such a 4kw inverter/charger will power all your above listed appliances more effectively with fewer batteries than the 20kva UPS.

The back up duration is a function of battery WH which you did not provide and not a function of the UPS power rating.

Hope this helps you

Thank God for His blessings. My solar panels have been producing average of 4500wh daily. Not enough though for my 21600WH trojans. but as soon as money smiles at me..ill add more panels.
9 pcs of 120w joy solar.
3.5kva sukham..48v
16 pcs of trojans T105re batts.
60 amps mppt tristar.

I cant imagine life without my solar generator especially with this heat wave . my fan and frige always working.

DUNKA:
Please how are these particular specs of your Trojan batts performing? Have u had any issues/problems?

abunafiu:

They are 6v 225ah. been using them since june. Never had a reason to add water. I rearly drain below 50% soc.

GeorgeD1:
pdozie,
i'm gald to know you were eventually able to repair your inverter. truly as akanniade suspected
earlier it came down to phcn power fluctuation.

personally i'm going to step up efforts and get the prag 10kva servo before i fall into the same
problem.
