You didnt state your budget, lemme assume you are a high roller like Niyi....

1. Morningstar 45amps mppt with display... 220k
2. Powmr 60amps mppt 30k to 55k.. dep3nding on where you buy.

around 60k max

is powmr a good product?

For standalone, If your cc dies in an off grid situation, which we all know you must have a gen for backup, you will still survive with your inverter . Besides all I have to find is a backup up cc and life goes on.(less expenses).
But in hybrid, cc get yawa you withdraw the whole system how do you want to operate with batteries only. Ok you get back up let me guess another hybrid (more expenses), or a standalone cc and stand alone inverter (more expense).
Any how you look at it, it also boils down how the devices are built, I have used my episolar standalone for 6 yrs no yawa, but within that period I have repaired and changed my inverter so many times no brainier. ..... N

When i wanted to set my system up, the seller sells both the hybrid and the standalones but strongly advised me to do the standalones if i can afford it especially since i will be offgrid and will be running heavy load consistently. That the hybrid will give issues after some time which will mean i will be out of power till it is resolved. He said he doesn't want me having issues in the near future.
And going by a friend that used hybrid and also advised me to do standalone, i think i still pitch with the standalones.

To sum it up. This is akin to comparing smf batteries.

The usa made batteries like Deka and trojans
retailing for 210k for 12v 200ah...
Then the quanta going for 140k.....
Then luminous, genus.... 120k.
Then the 1st grade china batts.. going for 105k
Then the 2nd tier china battery going for 85k.

Which do you think, most people buy and why?
My personal choice revolves round quanta and maybe luminous, am fairly certain only a small percentage buy the usa made batteries, you can ask the retailers as well...

Same issh in lifepo4.
How many people go for battleborns or pylontech?.
We all know they are better, but majority will not put down cash for them..... Majority will go for felicity and the like, while others buy raw Lishen and Eve cells.....
Everything na niche. How many units of latest range rover envogue are sold yearly... Vs latest rav4 or toyota highlander...... We all know range rover is a better engineered animal than toyota, but.........

Good point

Operating voltage?

12v, 24v, 36v, 48v, 120v etc
Which one?

24v

The reason i what to change to mppt is that my battery last longer when i charge it with nepa than when charge it my current pmw charge controller

How many panels you got? If your panels is not up to required. There is little mppt can do.

zeestone99:

1200 watts

1200 watts

Go ahead sir. You need an mppt controller. More panel upgrade is inevitable.

Cool! Could you share more experience on that hybrid. What's the actual no load consumption? what's the conversion efficiency as your load increases (load at 500 and 1500w is though)?, How does it perform with lithium charging? (I guess you are using it with Lithium?)

@earthrealm this is still pending your response o

durodee:
I have used both hybrid and standalone systems now for about 6years. My observations:
1) Hybrids easier to procure and deploy as per cost and ease of initiating newbies to RE.
2) Most hybrids seems to be having relationship issues with Litium batteries ( charging profile mainly) also estimating the SOC seems to be a challenge.
3) In a stand alone system if your inverter is faulty then your system is down same as in Hybrid situation- it's same same. Moreover, CCs aspect of my hybrids has never given me issues only the inverter part and I could believe that it's due to the fact that it's the one doing the heaviest work
4) Hybrids do not seem to like low grid voltages for charging. No issue with the bypass mode but gets stressed if also used for charging ( one of mine actually caught fire , real �) , could not charge anymore yet continued to invert for years afterwards.

My conclusion: which car is the best? Petrol or diesel cars? I hope you get my point

Hi Durodee,
Kindly permit me to disagree with you on the bolded. In the standalone system, if your inverter is faulty and you take it out for repairs, your batteries are still kept at optimal charge by the solar system via your CC.

If your hybrid inverter is taken out for repair, your batteries becomes vulnerable to the sulfation. It becomes worse if the batteries were already discharged (even if by 20%... Still having 80%).
Remember that leaving a LA battery in partially discharged state for more than 2 weeks leads to (temporary) sulfation. Beyond that, the sulfation starts crystalizing and can become permanent, and ur batteries becomes irredeemable.

CC hardly fails... They rarely do, unless misconnected or not properly sized. Let's assume I've done 60 Solar system installations over 7years; if 10 have had issues with the Inverter, not a single one has had issue with the CC. Not one!

However, even the premium inverters fails, even without warning. I have a client that his Magnum inverter got blown and it took about 3months to have the board replaced. The man was not ready to even buy any temporary inverter to use. His comfort was that his solar panels were keeping the batteries healthy. Imagine it were a hybrid inverter, no matter which section is wrong, the whole unit is going to be taken out. You'll have 50 panels on ur roof and your 1000Ah battery bank is suffering sulfation, because the whole inverter/SCC unit is out... I've witnessed about 3 experiences with hybrids.

No inverter is immune to failure (whether factory fault or external factor).
98% of people that always have intention of going for hybrid system is solely because of its cost saving. So, if your hybrid inverter develop issues and you're taking it out for repair, what happens to your batteries, especially if the repair duration would be uncertain? Would you then decide to get a CC to save ur batteries? Hmmmmmm

As a matter of fact, I usually try to discourage clients from doing hybrid systems. They are never rugged and reliable compared to standalone systems. All those monitoring and logging popular with hybrids are just secondary luxuries...

earthrealm:


maybe, maybe not....i recently operated the mighty Sorotec hybrid inverter, and i am super pleased with its functions and data logging capability, i have also owned/used morning star CC {my first love], so i feel am in a better position to offer an unbiased comparism. For a frugal/thrifty person like me...its a no brainer putting down almost 300k for a 60amps morning star CC, whn such amount will buy me a 5.5kva 48v Sorotec hybrid inverter that can handle 4500w panels [ this implies an 80 or 90amps inbuilt CC] and accept 500Voc panel input. and inbuilt wifi capability and you still have small change sef.

I believe you may have a rethink when you lay your hands on a well built hybrid inverter like sorotec/phoccos/easun/MPP etc.The world is marching on. standalone CCs in the coming years will be relegated to the background ---bookmark this.
again, not everyone will buy into them, but i believe majority of people would...

Lolz,.... First it was LA battery technology that is about going obsolete. Now, it's standalone CC... 22nd century fallacies, I must say... I might as well easily believe that Nigeria would soon colonize UK

ojeysky:


I hear that a lot and[b] makes me wonder; if the standalone CC dies[/b], what's the use of the standalone inverter that is still alive? especially in a off-grid set-up.
The main gist for me is that anyone that wants consistent power source should keep a copy of their hybrids or the standalones. May master J bless our hustle.

Bros, the bolded happening is very rare. When you hear CCs that have died, it's due to either not properly sized or battery breaker tripping and blowing the stuff. In ALL my installations over the years, no single CC has ever had issue. They're quite built to last. And that is why they're not meant to be repaired; but to be replaced if it goes bad.

But there are, and there would, always be cases of inverter failures, resulting from numerous factors. An inverter can wake up and decide not to function again! just like that o...

So, now compare when your standalone inverter have issue and u still have ur standalone CC keeping ur batteries healthy and when ur hybrid have issue and nothing remain... Ur battery is good as dead

As for the copy aspect, we know that's not rational. Someone can't just decide to buy two systems just because he's anticipating failure. We're looking at a system that is more reliable, Flexible, and most importantly, batteryLife-friendly

You gave valid points.

But the part you have yet to address is the part where the battery less option of some hybrids trump the standalone which usually does not give you that option.

Except like I said before, if there are MPPTs with high VoC and if there are standalone inverters that can work batteryless and the two coupled together, but even if there is, I don't think that batteryless feature can come in from there cos the high VoC of the batteryless hybrids is already software-tailored and integrated in the system to carry out such function.

Bàbá, I beg to differ o. Besides it's not like "buying two systems" the way you mean. Getting the reserve board is what is usually advocated for since that is even what most repair centres change in these devices. Besides hobbyists usually have devices that are dedicated solely for "carrying out experiments". So such devices can come in handy at periods of main system failure.

Maybe for clients that may not be willing to dole out more money to have that stop gap device in reserve. But for hobbyists and tinkerers that have enjoyed uninterrupted power for so long, interruptions can be an as5.

Even if you are on 5kva inverter, having a spare 850va for such periods won't be bad. The worst that can happen is that you won't enjoy your AC for the period you plan for repairs, but at least you get to run the basics - lights, TVs, washing machine and phone charging.

Lolz.
Sorry am replying late.
My lifepo4 bank is yet to arrive.
The Sorotec , isnt mine... So wasnt able to get all those info.
However the little i remember, On the Dc side it showed about 310w being taken from battery, and on the Ac side, it showed about 240w load... The difference is likelyconversion inefficiencies and idle consumption.

I intend to deploy mine sometime next year, so would be able to provide all such info you desire.

Like you stated, a balance of cost and functionality is the major advantage the hybrids have other standalone, if they arent massively cheaper, fewer people would even consider them..

I intend to either get 1 extra hybrid as backup.
Alternatively, i also have my cheap reliable 60amps powmr mppt and an old 12v 3kw el cheapo inverter lying around.
Any serious person in this solar biz should build redundancies into his setup.
In my other solar forum, some marine guys with huge lifepo4 banks on their boats, also have a small leadacid bank as bank up, incase of a catastrophic failure at sea of the lifepo4 bank, they could at least fall back on the leadacid bank to power their navigational and communication systems

Several years ago, like 10 to 15yrs ago the theory then was that non charging inverters are the best, since its just is just to invert, fewer breakdowns, and you can easily change out the standalone charger Etc..
Now such thinking has been proved to be flawed.
Science/Technology is evolving..... It will never remain the same

Good day my people... Viva FTA. Guys this is my battery and the charger information.... Pls can I get a minimal solar setup to charge this.... Our transformer don blow. Please help me mention the gurus in the house. Thanks.

My Batteries are 40ah...The real problem is getting a CC that can give the same output as the Charger. Thank you

CC Saipro

Greetings. I have this exact battery and I'm planning on going solar too. How did you go about yours?
Which charge controller did you buy and how many watts solar panel?

Have you found this yet? I have it, with Mate 3 and the 10 port Hub.

Powmr mppt cc has lithuim support and editable charge voltage. It shud be able to charge your battery.
1 single 300w panel shud be ok. For 1 or 2 of such battery as you posted

How many amps??

And the set up came with a dc distributor. Can I connect it to solar panel, charge controller and a ups??
