please what could be the issue, it just stopped charging now now immediately it went over 800w which it was not even supposed to do at the first place.

Check for these
-high CC temperature protection
-PV input over voltage shutdown
-BMS over voltage shutdown. Some batteries which don't have grade A cells are prone to this issue. As the cells get high delta voltages, one cell hits the max voltage while other cells are yet to get there and the BMS keeps tripping the battery off.

my installer has climbed that roof several times and my landlord isn't happy with it anymore, I want to be able to solve this issue without going to rearrange the panels again.

I stay in a rented apartment.

this is one reason I love high voltage set up.

Trippledots:
I think your panel voltage is above the maximum rated for your inverter voltage. Is your PV Voc above 80v?

my thoughts too. Because I use 2 PCs of 585w jinko panels in parallel and it works just fine in same CC (powmr)

Trippledots:
This is not how MPPT capacity sizing works... You can over panel your controller so long as you don't go over recommended voltage and amps.

You're still saying the same thing, recommended Voltage*current= Recommended Watts. The panel size (Watts ) for a 60A CC for a 12V system is about 720W. You can install a 1000W PV but due to efficiency, location, quality and other factors, the harvest may never exceed 680W, hence your setup may work well for you. It doesn't mean that if I copy and paste your setup in my location, it will work perfectly.

fuckboys:
please the charge controller went over 800w and then stops charging, what could be the issue. It's not throwing any codes

If you have reconnected the charge controller severally and same thing still happens,then it is most likely from your BMS.This is one of the advantages of smart bms to enable you see what is going on inside the pack.Try discharging the battery and let's see if it will wake up.Most likely one of the cells has gone above the over voltage cell protection value and BMS charge function is set to off.

I also think you are doing an overkill with your total PV input on the controller.

Get another controller and do 2s of the panels.

Omotoda (better person), getting another cc no be biscuit for street oo. .

Good morning Everyone .. My dad recently upgraded to a lithium setup So I have items from the previous setup available for sale . All items are working beautifully well and were well maintained (my dad no dey use his system play)

-Very rugged Indian 3.5kva soccer power pure sine wave inverter - 350k (brand new is about 500k) x2 pieces
-60a Roy solar charge controllers - 15k each x2 pieces
-Ritar Deep cycle lead acid battery 12v 200ah (less than a year used) - 200k ( brand new is about 400k) x4pcs
-350w panels - 60k each x5pcs

Location is lagos - Pickup and pay only..

The solution will be expensive, switch to a 24V system

Boss, yes e nor easy coughing out another 91k but it's still better than wasting 2 420watts panel in his present set up.The 2 in parallel will contribute less than 20am in his set up while he has potential.of getting max 60 amps with a separate cc.His battery is 314ah so it can conveniently chest it

Parallel or series or connection?

Boss,you will need to lower the prices of these items for quick sale..Anyone newly investing in Lithium now is better off buying hybrid.

Brand new soccer power 3.5kva is between 300k-350k,, so you see.......

fuckboys:
no my battery didn't even charge at all today with all the sunlight.

I had about 700plus watts around 11am then it kept increasing and crossed 800w before the c. Disconnects and won't charge again.

Please who has experienced this.?

I have your cc type which av been using for years now.
Its clear that with your step up, you can't get to 80v max.
Looking at the picture of your cc, it was showing that you have lost pv input signal.

Three things can only cause this, which are:
There is arcing at a joint along your cable;
If you have pv input breaker, the breaker has trip or bad;
The operation hours setting on the cc is not selected to appropriate setting, it's showing showing that your cc should be sleeping as at the time you snap the picture
Lastly, the cc input circuitry has developed an issue.

on the other, if your battery breaker tripped when the cc is pumping high current too can cause circuitry to developed issue but can still be lucky with it because I had experience that took and after switching everything off for 5mins, it bounced back.

Possible solutions:
1 trace your cable if it have joints
2 check all breakers, if possible read their continuity
3 disconnect pv inputs, battery cables, inverter
4 after say 5mins test your battery and inverter to ascertain their function
5 read your pv inputs with a meter, if it checks out
6 lastly reconnect your cc
7 check your manual and set

Hope this will help, if not you might have to get a new cc.

or get an 80a cc?

AV had 2000watts connected to this type of powmr cc before I switched to hybrid and what I have on it now is 1000watts and 2000watts on the hybrid

Yea like 100A to be safe, but upgrading CC may require climbing the roof to change the wires (I don't know your cable size)

Thanks chief.. I would do a quick price research shortly.. . The one i did earlier yielded different results from what you are saying.. I could be very wrong of course. So i would adjust the prices once i am done

Really? For a 12v system?.Fine then.I use same CC and keep strictly to the recommended VOC and PV watts limit.

Voc is the most important, the cc will not take more than it's maximum wattage even if 5000watts panels are connected. Just do your best to stay max at 70v to give headroom for weather changes.

I just read were ur system has been running perfectly not until I upgraded ur battery to anoda type. Now does this new battery have a smart bms.?

Dam5reey1:
Deye na better Soup oo..

Efficiency 97% DC to AC conversion stop wasting unnecessary power in conversion. Even 5kwh batteries will last very well.

1750/1800

If you have 5kwh batteries, this will mean you can use 4850wh on the AC side compared to most inverter with 87%, which gives on 4350wh.. a whole 500wh saved..

About 97% .......This is impressive.
After seeing your post, had to check mine. Damn the difference opor.
Mine ranges from 83% to 90%. Poor at low loads but fair a bit when the load is more than 1kw.
I feel the most objective way to check for efficiency is to drain battery from full to LVD and see the cumulative DC energy(Kwh) converted by inverter to usable AC energy (kwh)

no it does not have a smart bms

Parallel on a 12v set up. Series will pass the allowed voc of 80v. One 585 panel is 52.45V

So bad. A cell can be causing all this palava

I doubt, in damis review he was charging the battery at 60a(haisic 12v inverter) even though the recommended is 40a and maximum 75a. Check your pv breaker or inspect your cables

Do the @valto 15kw batteries come with comm ports?
Can they communicate with the inverters?
What kind of accessories do they come with? Is it only the batteries as shown in the pic as is?
Do they come with warranty and how many years?

Would love to know from Valto himself or from people that have bought his batteries. Thanks for the info
