Wait till tomorrow...

U dey whine me abi.. I fit still reach out to u for that mppt if my plans click well.

I have come again ooo with my inverter palaver. Finally added 2 300watt panels to make 1500watts on my 12v hybrid and input went up to 550watts from 350 at peak hours. However i know from small geography and online gist that the sun move from east to west but which one is now sun that was facing my panel when I install initially is now behind it. My roof is south facing by the way. Pls when wud the sun come around too if u know 🤣🤣🤣🤣

Jefferyzz:
SMS hybrids are decent,I have installed 2 this year and no fault so far. I'll advise u look into 24v rather than 12v. Max Ur battery will charge is 960w

What do u mean by ur last sentence? Not clear

Hello Guyz,
I just needed a professional opinion on this.
I currently have a 12V system with 1000W(4X250) PV in use for about 3years connected to 2 220AH tubular with a 60A CC.
Experience has been good but I'm thinking of upgrading to a Hybrid system. Reasons been that I want to do it in phases myself.
Base on the research in this thread i was able to drill down to the following hardwares:

SMS Hybrid Inverter 2kva/ 2000W 12V (Mppt 80A)
625W X 4 Jinko PV due to space.

However, based on my research, I'm skeptical about the inverter ability to handle the energy from the panel or go the route of upgrading to a 24V system with 120A CC with same amount of panels due to space.

My questions are:
1. Has anyone used that Inverter and whether it can stand test of time.
2. Based on the ratings I've seen for the inverter being 4000W for PV, with it be able to handle future PV addition.
3. Would you advice upgrade the system to a 24V system with 120A CC.

NB: Everything is within a budget and can't exceed but has been prioritized.

All opinions are welcome.

Does ur present system charge ur batteries full? Guess u combined batteries in parallel. How did they combine the panels for you? Is the CC Pwm or mppt? Max a 60amp wud take theoretically is 720w and u using 1000w of panels
To answer ur question
1) Its actually 2kva/1600watt inverter. 3mths old now and doing its work. Comes wit 1 year warranty
2) The max panels u can use is 3000watts
3) why do u want to change ur CC. Is ur present specs not carrying ur load. Since u already av 2 batteries, I'd advice u just get a standalone 24v inverter, change ur battery to series and add more panels to ur CC

durodee:
I will advice you STRONGLY not to sell. You will not be able to get it at the price you sold it if you need it back . Moreover, you won't have any backup in case anything happens. Find money for your upgrade. You will have reasons to remember this advice in the future.

I'd keep mine if i was in his shoes too but then he knows whats best for him

obinna37:
thank you so much for this,many people are afraid to buy hybrid inverter because of difficulty of repair

I have my shortcomings with hybrid based on my experience. If its a 12v system, I'd advice standalone systems. Advantage of the hybrid is it wud take more panels compared to it's standalone charge controller eg my 12v hybrid can take up to 2500 watts yet the mppt won't go above 720w theoretically

Sapiosexuality:
Exactly what I will do. I will sell it. I'm getting panels first. Then inverter and battery.

I'm interested if the price is right.. whatsapp zero 7035seven1 twentythree 88. Thanks

obinna37:
sorry if I may ask, which of the device did he repair for you, what's the fault

Brand new must 5kva hybrid inverter that refused to supply load after setting up. Repaired under warranty.

Deluxe8000:

I want the best possible combination to generate enough power from the panels to use at the same time charge my battery. I have 2 150w 12v panels. I need to add more panels.

U should av just stated ur panels spec and nos and the battery set up u want to use it for. Also type and specs of solar charge controller. The experts can then guide u on how to go abt it

luvlyoracle:
Just asking if you use all these dumb inverters without editable settings and you don’t have solar what’s the best way to charge your lithium battery.
Would really appreciate y’all input it’s been giving me issues lately

U cud get a dedicated lipo4 charger and use with a satchet inverter

kristien4:
hello boss, do you use breaker between your inverter and battery, is it advisable??

U didnt mention type of inverter and battery? Some inverters wud recommend putting a breaker between them and the battery so check ur manual too

Good evening

Please I have this kind of configuration setup in my apartment

5kva 24v Inveter
400Watts Solar panels (5)
220ah battery (2)
60amps charger

My question is whenever I try charging with Nepa light o shows it fully charged within few minutes but when it’s on resting stage meaning when it not connect to any form of charge and I check the battery I get 77% even while on solar it shows it fully charged but at the end of the day I see 75% please how can I get it charged to 100% or should I just ignore the fact that it say fully charged and continue charging please any help would be appreciated. Thank you 🙏🏾

The 75% u are getting could be a factor to voltage sag common with tubular batteries. Could also be a factor of the load u put on it

Trippledots:

You put about 2.5kva load on your lead acid battery?!!!

How are we even sure the panels capacities are real, the size of PV cables are optimal, etc

Your installer didn't give you Dos and Don'ts for your type of system Abi na those type of installers wey de promise 24hrs on top 2 battery....wahalad.

Let me give you some tips for this battery
1. Ideally You shouldn't load your batteries more than about 500watts.

2. You should not use your battery below 50% which is roughly around that 24v you are seeing.

3. Ensure electrolyte level is within range using the hydrometer screwed on it.

4. Ensure your battery charges till float after every deep discharge

That 55% wud drain his batteries to 50% in less than an hour. Reduced lifespan too for the batteries as he's drawing almost 50amps from each battery.
Perfect recipe for failure. He needs to sit his installer down to explain what he did and how to pamper his system.

What do u mean by 'continue charging'? The inverter/charger sud trip of once battery is full. What's ur load like during the day? Ow many percentage is ur load? Ow long do u run it before it reaches 50% (24.0v)?

adeshina36:


Currently after charging it since morning this is what I get as the voltage. Just about to use now to know how many hours in total it will last.

I'm seeing 55%, is it my eyes or what's showing? That 24.0 means ur battery is already at 50%

Have you asked nicely and I said no?

Let me ask nicely... Can i av the 5g router. Wud be a big upgrade to my 4g 😁😁😁

walexsos:


Its 38v that is on the panel while i get 103 for the 3s combination.....note ...i am not an installer if my answers aint adequate enough

If ur panels VOC is 145, then u can still do a 4s connection. U already at the upper limit of what ur charge controller can take so adding panels wud be putting it at risk. It cant take more than 3300watts and u already on 3600watts already.
Does ur battery get full during the day? Ow much is ur total loads during the day/night? U may av to upgrade ur charge controller to 80a/100a if u are to add more panels. A lithium battery wud be a good replacement as it can take a higher charge current but this wud only make sense if ur present battery bank is weak already/needs replacement.

walexsos:



The voc of the charge controller is 145v

U didnt add ur panel's own

Anyone wit a functioning 60amp mppt they are not using or willing to dispose of at shikini price? Pls holla 😁😁😁

TechGeek777:


Growatt is far better, heard Gennex is not too good with warranty on their inverters.

If you are not getting VICTRON, get DEYE, but if Deye is above you budget, get GROWATT, if Growatt is still above your budget get SRNE.

Any high frequency inverter outside above 4 mentioned inverters, just get SMS Sunmate Inverter if going for 24v or 48v.

NB: iPowerPlus 5kva is still good if going for low frequency inverter.

Must inverters nko?

Penuelseun:
My old powmr has a bug that sometimes changes the controller to pwm mode when the battery gets full and load is applied, I will have to switch the solar input off and on a few times before it returns to mppt mode, note that this only happens on 12v batteries, never happens on 24v systems

Oh ok. Thanks

isangjohnson:

I used HSI and Zumax. If the panels are well oriented and the correct size wire was used, then the charging system of the hybrid inverter is the issue.
I had an issue with of one of the hybrid inverters I installed for a customer and suspected it was related to float bulk.. I was unable to get an acceptable margin of float bulk that could comfortably charge the Lfp battery to full. When I set it to the range of 13.8v to 14v, about 9a or thereabouts was coming in from the pv but when I pushed the setting further to about 14.8v, I was seeing 25a and above. I couldn't charge the Lfp battery with 14.8v and I later introduced my spare 60a epever Mppt external CC into it and everything was in order.

Yes, they facing south and are connected in series with a 6mm wire. Tried ur settings but nil change.
At a point was getting abt 180w from the panels but only abt 5a is going into the battery. Highest amps gotten since av gotten it was around 11a and that was when no loads on it and abt 350w from the panels.
Bin advised to get an extra panel and if no change, wud get the external CC.

dollarnaira:


I noticed you are on a tight budget so you need to manage what you have to survive. You can easily be advice here to go 24v if you haven't purchased the above.

But if the above had been purchased, probably my set up could give a fair hint.

3000w 12v satchet inverter
2s 300w africell pv
Powmr 60a ( max 700w, 80v)
Pv is almost flat on a fence airflow is great.
78ft (26yard Ethernet cable in place of regular cables ).
Battery: 105ah LifePO4

Load mostly in the afternoon: 115w freezer( most important), 50w tv, 10w decoder, 35w fan, etc.

Freezer from 9am to 3 or 4pm.

On cc I do get max of 31a at 478w when sun is blazing.

As freezer goes off by 3pm, battery jumps to 14.1v b4 6pm.

Night: Tv, 1 fan and lightings till say 10pm.
2 fans from 9 or 10pm till morning at a fair speed.

Battery drpped mostly around 13.0 or 13.1v in the morning.

At times tv goes off as sacrifice for freezer in the afternoon when sunlight is just fair.

TRY CHARGE YOUR BATTERY FULLY FIRST AND CAREFULLY DISCHARGE AFTERWARDS. IF You discharge with sense, this 12v of yours will work. But in the long run upgrade to 24v to enable you utilize max your 1400w. But the economy could hinder an upgrade.

N.B Attached pix was today

Pls would love a pic of ow u set ur panels on the fence

walexsos:
hello everyone, I have been following this thread for quite some time and sincerely I appreciate everyone for keeping the thread alive....

pls I have a setup of 48v system of sukam 3.5kva transformer based inverter and 4 pieces of 220ah mercury tubular batteries which I use to run my viewing centre( whenever there is football matches at weekends and midweek matches at night) and gaming shop but it doesn't serve me for 24hrs as it's also connected to my room at home which I use after closing at the shop around 10pm
note.... ( I only use it to power few energy saving lights and ceiling fan at home from 10 pm till the next day)

I used 12pieces of 300w panels which was arranged in 3s 4p with a 60amps felicity cc...I am thinking of adding 4 more panels but I am not sure if the cc can accommodate 4s, 4p, below are the gadget used at the two places

game shop
2 slim PS4
4 slim PS3
2 42 inches 4k smart
4 32 inches led tv
2 AC/DC fan at the game shop is


viewing centre
3 50 inches smart TV
2 62 inches ceiling fan

pls should I add 4 more panels or just upgrade to lithium battery and what capacity of lithium battery can run this loads conveniently and still have enough back up at night if need be

Pls post the VOC of ur charge controller and also of the panels used before u can be adviced correctly on ur panel combination pattern

Penuelseun:
Nope, I now use a 60a Must cc, panels are connected in series

Oh ok. Any reason u chabged to must? Does it have a higher VOC for 12v than the powmr

isangjohnson:

I may not really understand what you mean by "an average hybrids require large panel arrays to power loads and charge at the same time" but I've installed 1.5kw 12v hybrid inverter 150v 80a with 2 pcs of 580w Longi pv and 280ah 12v Lfp battery for someone. He powered his 140w freezer during the day and still get the battery to float before 1pm depending on how deep the battery was discharged at night.
I'm expecting 1kw 12v and 1.5kw 12v high frequency hybrid inverter next month and I'll still test the charging system as well.
The issue you experienced may have caused by the configuration of that charging system by the company.

Whats the model of the hybrids. The inverter i use is connected to 3 300w panels and a 12v220ah tubular battery which rarely gets full unless there's NEPA. Have the same system at 2 other sites and its the same outcome.

Penuelseun:
8am to 6pm daily except in periods of bad weather, changed my panels to 2 435w jinko solar panels and so far their performance has been exceptional

Do u still use the same 60a Powmr SCC? If yes, ow do u overcome the voc of 80 for 12v seeing as ur set up surpasses it if connected in series?

isangjohnson:

Dam5reey and Penuelseun advised you to go for the 24v system because of the set-up list you posted. The advice wasn't necessarily for your stated loads.
2.5kw inverter and 1400w pv were also designated for the 24v system and that was the reason they told you to change the CC from 60a to 80a and continue with the 24v system at once.
If you've not bought those items yet and you intend to reduce the cost as you clearly stated, then go for 2 pcs of 580w Jinko or Longi pv, 1.5kw hybrid inverter and 12v 160ah lfp.
This can comfortably take care of your freezer during the day, few lighting points, tv and energy saving fans at night.

Unless he's getting a high quality hybrid inverter, he's better off having individual components. From my experience, the average hybrids require large panel arrays to power loads and charge at the same time. Use a small array and u wud be dependent on grid for optimal charging unless u add an external charge controller
