I have 230w x4 Solar panel.
I need a 3000w+ 12v inverter with low standby consumption watt, possibly an hybrid with internal MPPT Solar Charge Controller.
Any suggestions?

mank1234:


The yield is impressive.
I'm wondering why folks would prefer to spend almost double on brands like solarworld!

Barezzi:
Quality?

dapsyra:


For longevity, safety and extreme temperature (-20 to 55 deg Celcius), Lithium Titanate Oxide (LTO) battery is the best of the Lithium battery family.

With cycle life >10,000cycles at 80% DOD, they can be fast charged from 0-90% in less than 10 minutes at 10C without thermal runaway. The only down side is that they are quite expensive.

I have somethings off my sleeves concerning LTO batteries. I might have limited quantity to sale soon, being leftovers from a classified project.

Please stay tuned on this channel for the announcement in Jan/Feb, 2018

Lithium Titanate Oxide (LTO) batteries are already here

I have used part of it to replace my AGM and Flooded Lead Acid batteries.

I will have a small quantity to dispose off when we finish the project we imported them for.

My oga long tym, u jst pack d lithium ba3 for ursef alone, pls give us reviews,since u didn't send me one for testing ..... Dat smal quantity u r talkin abt, are they ready for sale

I have since learnt not to buy these so called high quality high-tech equipment where cheaper equivalents exist.

The quality @Barezzi mentioned as reason to buy high priced brands translates into two factors; performance and longevity.

Performance of top brands might be better than their Chinco equivalent on the surface but when you factor in price differentials the story might change. I most cases, performance difference is not more than 20% (where it exist) but price difference is in the order of 30-100%. On this point, one is therefore better off buying the cheaper Chinco version.

Longevity on the other hand is also not a very good factor to consider when buying High-Tech gadgets. Today's state-of-the-art gadgets will be obsolete in one or two years. While the equipment might still work very well, the allure for improved performance and better features will force you to drop the equipment long before it's end of life. If I may ask, how many people are still using that expensive, durable Nokia 3310 we all bought back then? New technologies have since forced us to retire it despite the fact that it is still working perfectly well.

One of the main limitation of Solar Panel deployment is space. I give you a practical example. More than ten years ago, I purchased and installed my first set of Solar Panels. They were 4units, 80W mono panel. Very expensive state-of-the-art panels for those days. Three years ago, I decide to upgrade because Solar panels have become cheaper, more efficient and smaller. I purchase 6units 300W Chinco (Roysolar) panels. Although my old panels were still working very well, I got rid of them because of space inefficiency and backward incompatibility. The space occupied by the old 320W panels is now sufficient to mount 900W of the new panels. Who knows what will be available in another 10years? Most of us in the forum will gladly get rid of our current "expensive" panel if a new technology suddenly appears that shrinks the size of the panel by half. This will allow for installation of more wattage on the same space.

With my Chinco panels, I have harvested more than 10MWh and it is still going strong with an efficiency of over 4kwh/kw on a sunny day. How many people with the high priced panels have efficiencies that is better than that?

If you are just venturing into renewable energy, I seriously recommend that you don't throw away your hard earned cash buying high-end products. You might just be paying for the name and durability that you don't need. Look out for equally good cheaper alternatives with the features you require. New innovations in technology will force you to replace it before their end-of-life.

After all, we now live in a disposable world, as far as technology is concern.

I agree with you on all counts baba... It's the reason I'm still waiting for price crash before going Lithium

Ijeoma660:


Please I think I would be very much interested in trying them out, as I am about replacing my batteries. Can we talk IM or whatsapp?

Lithium prices would reduce to a point then it would go up. Lithium is a rare earth material concentrated in few places of the world. Once it goes mainstream it comes gold and the value would shoot up higher than manufacturing process can reduce. I am average lithium prices will not be crashing in a long time

hello house, anybody being able to repair a faulty morning star mppt cc?
likely cause of fault is exceeding voc. 5yr waranty has also been exceeded.
would appreciate any helpful input.

Which of flames, Myhome, yachi, sunshine is more reputable brand?

NiyiOmoIyunade:
You may talk to Zeestone99 - he was able to fix the one MorningStar I had that blew up after a sudden MCB trip. He took it to Alaba and got a repairer to do some magic - I of course couldn't trust the controller again so I sold to him and he is still using it till date and it is going strong.

Cost of repairs could be exhorbitant though - I would rather buy a new one and this is exactly what I did in my own case.

How did you manage to exceed the VoC limit on the CC? Experimenting with 4 panels in series? or some sort of solar flare happened or what? If you can eliminate hardware failure, I may be able to help with reprogramming the MorningStar.

I will go with MyHome anyday. I had six 150w mono from Frankie & still firing almost 2yrs counting. Very reliable beast.

Did I read the picture right? Slightly over 4 hours of 'absorption charge'? Odiqua risky o bros! That is a rather long period to stay in absorb. Are your batteries FLA/Flooded

Think positive grid corrossion

Just as oga idsolar suggest to me on phone in December, I climb my low roof bi-weekly to clean my PV and I have never been disappointed.

Am beginning to feel my neighbors think Solar get wahala joor even though I have dedicated an extension bracket for their phone charging.

DIY stuff not a rule

I currently have SLA batteries and GEL batteries joined as one bank (both lead acid anyway).
I set my absorption at 14v and floating to 13.6v. I can't equalize gel batteries @ 30v so I had to extend my absorption to 4hrs which works fine after testing 2hrs.

My overnight load is 140-200w and still have 65-70% in my batteries by morning. I run 24hrs TVs, DStv+strong+startimes nite or day. Freezer+fridge off 4pm to 9am.
Finally, I get about 5-6hrs of grid a day which is irrelevant if it comes during the day.
