what's the best price you can sell it

You've already bought that one. Abi you want another one? Lol

Anybody knows where I can get new Victron CCGX module to buy?

ojesymsym:
Nothing to worry about when it comes to repairs with those big brands, infact their repairs is usually the most straight forward. Once you identify the exact board that is bad inside, you buy a replacement, slot it back in, connect the different olugs back and your inverter is back to life.

It is even all these chinese hybrid boards that solder all the different parts of the board on one board sef that you start having to trace resistor, ICs, capacitors to replace.

That price is a steal. I have a used 10kva victron unit and I probably have to really love you to do N1.5m for it.

How true is this statement please

"Lithium battery is crashing. Cells that cost $2200 for 14kWh is now close $900. This means you can have 8kWh lithium battery grade A for less 500k. That is the about 3 Tubular battery worth of lithium. Lithium prices crashing so fast naira inflation is struggling to keep up"

8kwh for 500k?...where abeg

saint2ace:
This assumption is wrong, it works doesn't make it optimal, but that's a subject for another day. Cheers

Wrong? For two lithium packs?

Toh....my oga av spoken. 🙌

Allem:
I dey interested

DM. Although another person has indicated interest, but who pays first picks it up.

Just want to recoup money.

Disco01:
See the information and know if something can be done

It's the manual you will check, not chassis.

saint2ace:
Alternative inverter brand will be based on your budget, so please share the amount you're comfortable spending on a new inverter first.

Secondly, get Ur installer to separate those battery cables, let the positive be on one battery and the negative on the other, this will aid even current draw between the 2 batteries connected in parallel, as it stands, battery 1 is taking all the hit and will charge and discharge faster, while battery 2 is in limbo.
If you have a high influx of current higher than the BMS capacity, then Ur battery BMS may clip the current to save Ur battery and that might be part of your problem.
Preferably, get a busbar, connect both batteries to the busbar independently with equal length cables, then connect to your inverter from the busbar, that would be the ideal approach and will aid balance out Ur batteries too.
Just my 2kobo.......

I think he is fine with the battery connection since they aren't Lead acid batteries.

Disco01:
The inverter doesn't support lithium charging profile but I'm ok charging with solar alone.

If the inverter battery charging settings has "user" option, you can tweak it for lithium use case. Just put your absorb at close to your full battery voltage. Turn off equalization or set to same absorb voltage.

Penuelseun:
What is your bulk absorption voltage set as, I think one of the battery cells reached a high voltage thereby triggering the high voltage disconnect which caused the bms to shut down the battery thus damaging the inverter. Solution is to reduce your absorption voltage.
On a second thought, what did your installer state as the cause?

Exactly my thoughts. Some installers are just careless, that's how a family member inverter got damaged because installed didn't adjust CC charging parameters. Battery went to 57+ volts.

SEOSpecialist:
Experts in the house, kindly proffer your advice concerning my inverter setup.

I have a 3.5kva SMK Inverter with two pieces of Cworth Energy 2.5kw Lithium 24V batteries (as seen below) and four 380w PV panels. On Wednesday afternoon, the inverter let out two loud sparks and started displaying error code 09 (this would be the second time within three months). A technician suggested that the inverter may not be compatible with the lithium batteries and suggested I replace it with a 3kva Felicity
brand.

Does anyone have an idea on which inverter brand will be most compatible with the batteries?

Thank you.

Did you sync the battery specs witht eh inverter battery charging settings?

Anybody with cheap solar panels for sale in Warri
I need like 600w I have 150k

I have two PCs of 320w used Jinko panels for 150k.

If interested let's talk

any contact pls

Unfortunately no.

LOLZ...so cell stations running in remote locations 247 with inverters and automatic kick over gens......is wrong?
adequate protection is key, i hv been out of town for weeks and left my freezer and inverter with solar and grid powered on..zero issues

Ok boss. ✌️

tee2faith:
Please I need guidiance and advise from gurus here. I got this Solarmax 8MT2 Inverter from a friend abroad, although I am not a very technical person but I noticed that the specification of the voltage reads 400v or so. Please can this inverter be used in. Nigeria?? What is the implication of the 400v instead of the normal 220v. The picture of the inverter and specification is attached.

Hmmm...3x400v? Looks like a three phase inverter.

That 900v max Voc is 😍

What type of balancer do you have?

JoeSef0:
Hi guys
Has anyone used this CC before
is it any good?

I told my guy to get a 60a Powmr charge controller
He said he will look for it in his city only for him to come back with this one
And the max pv voltage is 100v

This is pwm. If you are in Lagos, you can get from sellers here and send to him via transport buses.

Like the breaker was switched off?

You mean PV breaker? No, that was still on. But the inverter was switched off.

Nutridelfarms:
Hello Guys,
I just installed a 6kva inverter system. The inverter brand is Gospower (6kva) while the battery brand is Marstek (5120Wh). This combination was recommended to me by someone. It's been up to 3 weeks since I installed this system and I am not yet impressed. The first issue I have observed is that I hardly get up to half of the total power output of the solar panels (10 x 330W). I understand it's cloudy but the few times the sun has shone bright, the maximum output is usually around 400-500W.

Second issue: I observed an anomaly yesterday when power went off. I observed that the voltage on the inverter panel dropped drastically to 48V from like 54-55V upon disconnecting from the power grid. This was shocking to me. Then shortly after that like 5 mins, the voltage dropped further to 47V which triggered the inverter to shut down. I had set a low DC voltage of 47V. My load consumption is very small - ranges from 200W to 400W. 400W during the day when the industrial fan is on. All other appliances are basic.

My next course of action was reaching out to someone to come do an independent troubleshooting and inspection as I can't tell where the fault is coming from: inverter, battery or the installation. Secondly, I contacted the battery manufacturer to complain about the issue and they promised to send a technician over.

I'm still in shock as regards what might have caused this issue.

First Pic was taken shortly after power went off showing the drastic drop in voltage.
Second pick was taken upon restoration of power in about 10 mins when it first went off. As you can see, the battery charge status shows a fully charged battery and voltage rose back to somewhere between the float and bulk voltage.

You sure those panels are real capacity?

Actually, I don't think they are because i monitored it my self.. And according to the low and high volt I wrote above, that exactly what in the manual book as well... Was kind of expecting bulk charge at 29v or 28.+ but on the inverter and manual as well it is written 27v and 21.8 as low.. Reason why I said they don't use pass what is explained is, this ppl na my inlaw, Dr follow instructions like say his life depends on it... If you tell him not to on it all day self, he won't ask why since it your field, he will off it that him for you.. Now back to the problem, do you think the inverter could be affecting the batteries? Could it be that pumping machine affecting them..? Kindly not, the pump was only tested on the previous battery not run on them and them just went bad before this new ones.. Now this again..

My setup once again make una help me use Oju a gba wo abeg..(experience eye look am)
585w brand new jinko PV all connected in series x3
Welion 4.2kw hybrid invert with 120a cc
Then two 220ah tubular batteries.

Load.. Pumping machine 1HP
Inverter fridge/freezer.. At high 280w and when it start running it comes down to 80w at low.
Tv 32"led which is around 35w or there abt
Decoder.. Around 15w
Then DC bulb 5w btw 5 and 10pecs sah not sure..

Kindly note pump is used only when the intensity of the sun is high and na like 3 or 4 days interval. (they once share with me the clip when they on the pump, the PV took it up.. And the battery never left the bulk state. Pump was taking around 700w+ and the PV was bring down 900w+ and once the water is full and turned off the PV will come down to just 100w above what ever it is been drown from the inverter. It doesn't event touch the battery at all..

Tv.. This only comes up during the weekend..

Refrigerator is the only appliance that run on it from 8am to 5pm now i tell them to off by 3 since this issue came up.. Kindly note that even as at that 5pm they off it, the battery stage doesn't leave bulk state always full...

With all the listed above, what the way forward.. Contacted the battery seller alaye turned me for one side.. And this Instllation was done in May last mth..


Kindly note... I Hv customers that they run two 12v 220ah tubular with 24v system on pump for year with no issue.. So i don't belive that the issue pls.. One even use it along with his old fridge in his drug store.. But i always advise them to do so hen the sun is high.


Make una help me with solutions pls.. Should i take batteries to professional battery chargers for check up? What could be the cause of all this.. Pls i need solution bosses abeg 🙏 🙏 🙏 keep on seeing messages and WhatsApp calls from him asking for way forward always cut my mind 😔 😔 will be in the comment section. Thanks all.. One love

Increase your PV array, ensure they don't go below 50% DoD, batteries might need equalization

Update

Hello chief, gone there yesterday and did few of the things listed here... (Equalizer also changed the battery settings to flood on the inverter) .. Also went with felicity 60a cc sadly that one doesn't accept more than 145v but was still able to use it to charge cause of the poor weather although when the sun intensity increases, it started blinking the warning red light. Anyways that not where am going... what I noticed myself is that, the battery doesn't take more than 10mins before it runs from full charge to completely discharge which is from 25.+v to 21.8v. and also takes abt same mins (10mins) before it get full even to bulk and float level. Let me also call una attention to this, initially when i did the installation, they had two 100ah battery which i connected to it, after abt few days the batteries became so weak and dead. I was like maybe because they've been using those for going to 2yrs maybe that was why, then we got another one.. Brand new ones this time around two tubular batteries 12v 220ah then this issues again which am just so so confused ... I also noticed the battery will start decreasing just like a clock count down.. It doesn't back up at all ones the PV is been cut off.. Same thing the previous two 100ah did.. what is the way forward, what kind of solution can I use to tackle this problem pls.. Will be in the comment section... Thanks all..

Mixing of old and new battery is never a good idea.

Edrizz:
Recheck n confirm that the battery equaliser is installed correctly cos I don't see it performing it functions of equalising the battery voltage according to the voltages u shared earlier.... ordinarily you're not suppose to have any disparity between the battery voltages...

Mine has same issue as. Initially my batteries were balanced but after some months I noticed significant drift. Mixed up the batteries but same thing.

I fear I may have broken the equalizer during reconnection or I need to reset the equalizer.

Either way, my schedule hasn't allowed me to work on the bank again.

obitobe:
Please i need expert knowledge here, i have four 220ah tubular battery, i just noticed that when the battery is fully charge and i start using it for the night, @136w(5pm-10pm) and 98w ( 10pm -7am). i noticed that the battery will be 24.2v @2-3am then between 3-4am the battery voltage drops to 23.4v and this will get me to the morning. Recently i had to set the battery SOC from 50% to 70% because at 50% the battery goes off at 5-5:30am but at 70% it takes me till the morning. What could be causing the sharp drop in voltage.

With a battery monitor, i am getting this readings in the morning Batt 1: 11.95v Batt 2: 10.99v batt 3: 10.95v Batt 4: 11.94v

You need a battery balancer. If you can mix the the battery configuration again such that one high voltage battery is paired in parallel with a low voltage one.

mank1234:
1 and 2 is going overboard. Lightening do also happen before it rain and sometimes while grid is ON...

Personal, I don't think 1&2 are overboard if they are not very expensive to implement.

That was even where my mind was playing towards before Jones dropped them. How many times does thunder strike when there is no rainfall? Little to none actually.

I will do some market survey and see if it's a cost effective solution.

My panels are not on the roof because of this.
Lightning seeks the highest conductor

This was my thought initially too until last Saturday when a client I did a fence PV installation that's about a year old with no complain whatsoever called . His system is off-grid, sachet inverter, switched off during a night thunderstorm.

He came back to find his inverter no longer working, but controller and other devices working fine.

I'm still wondering what happened.

2 other tenants with roof installation had their on line inverters taken out also.

I have seen that you are good on this diy as people have recommended you to potential clients.
Please I need something to charge phone at least for now as my area haven't seen NEPA light for the past one year and even no hope in sight coupled with the current tinubulation.
Tired of paying public charge outlet (N200/day)

I don't know anything about diy and hope every every be done by you.

Wow...where is this location please?

FEGEITOK:
The grid connection was an oversight.

I intended to disconnect.

This isn't my first time traveling and leaving the stuff connected.

I don't know if it makes a difference but my house is next to an AEDc transformer.

And I know they do proper earthing for those things.

One of the transformer earth rods in my compound.

I'll seek advice if I can link my own earthing to that one.

Appliances can go crazy at anytime. I'ld strongly advise never to leave energized equipment running unattended to for long periods. wether connected to earth or heaven.

✌️

FEGEITOK:
I traveled for 3 weeks.

I just returned.

I left my inverters hooked to my solar panels.

One was connected to utility power.

The other inverter was not connected.

I reduced the loads such that even if the sun was not generating enough PV power the batteries would not run out.

Would you have done what I had done or would you have powered down your unit or units?

I came back to meet everything as I left them.

I'd love your responses with reasons.

And by the way the panels are earthed and every earth is connected to or bonded to each other to be safe.

If I don't have contents in my freezer that needs to stay iced up, i'ld power down my inverter, manually disconnect grid, leave my battery and solar side connected.

Reason: SAFETY FIRST. It's never a wise idea to live energized equipment unattended to, especially for long periods of time.

idsolar:
Wow nepa 119v. Like what I got on one site here in KD. Infact I was getting 110, 108v. Site steady on 220v now. Na servo boost am o. Jordy-ele servo, na Zeestone run am

And to think that the more stabs (inductive loads) connected to the grid, the poorer the quality the power on the grid gets. The govt. has failed us woefully.
