The two days sun made my cc to lose memory oh... Because of excess. Just do 4 panels for your 24V setup.

mank1234:


Voltage of the inverter does.
A 12v inverter will do half of what a 24v inverter will allow. 24v inverter will allow half of what a 58v inverter will.

harizonal123:


How about connecting all six in parallel? Is there any implications

earthrealm:



In what way my brother?.
Cc is the only limiting factor, for a 12v, you would hv to run multiple cc, if you want to have panel array above 700w and still use 12v inverter

ceaser:


Lose memory as how?

ojtech8291:
Stopped charging until I have to off and on the breakers. It happens every time the sun is very high.

mank1234:


For a 60A cc that support 12v, 24v, 36v and 48v setup, is it not the inverter that will determine what voltage you run the CC?
If the inverter determines the voltage you run, it then determines how many Watts the panel can be since the CC cannot go beyond 60A.

If your inverter is 12v, you'll run less panel than you would on a 24v inverter using the same cc.

If you are to run multiple cc in order to achieve same wattage at lower voltage, then it's not the CC that determine the wattage but the voltage of the setup which is dependent on the inverter.

The inverter is a true PSW. And a good one too. If AC power is good, it charges well (20A charger I think). It has a lot of battery, load and output info on the display, but unlike some in its category, there is no way to turn the various displays on the screen off.

spartacus11:


You mean one can connect multiple CC to one battery bank?

earthrealm:


Haha..your connection is wrong...likely overloaded the cc above its rating

dapsyra:


Your CC is probably going into protection mode when the sun is very high due to one or more of the following scenarios.

1. Over Temperature. The temperature of the FETs have gone above the safety threshold due to continuous operation at maximum power

2. Over Current. The output current spiked above the rated capacity for a sustained period

3. Over Voltage. The input voltage rose above the rated MPPT voltage

You need to rejig your array to avoid these issues.

spartacus11:

ojtech8291:
It should be over voltage because the VOC of the series connection is little more than that of the CC Maximum input voltage. Maximum CC is 70V but the panels are 2S is around 77.6V. 1S4P will result to a lot of voltage drops. The only solution now is to change the CC. Thank you.

ojeysky:
Why I may continue to get sunfit panels if I can find them. That is from a 2.25kw array, what else will premiums do than this

Note that it could have gone beyond if not for BMS limitation

ceaser:


I actually have one that I have retired. Very good product like that. Used for a year. 12v "BTS" PSW with AC charger with 20% 50% selectable DoD. But it's 750kva so I'm not too sure if it will handle your load. I believe the highest KVA with 12v in that product line up is 1.2kva. Higher KVA come at 24v nominal. It was bought off of Konga. I'll see if I can retrieve the link.

earthrealm:


Hahaha. You are very lucky , that you didn't burn the cc, you were told b4, ojesky encouraged you to risk it

ojtech8291:
Lolzzzzzz...The CC has very good protection but very bad in terms of array manipulations. It is called solarmate charge controller. Who has used it before?

dapsyra:


Yes, you can connect multiple CC to one battery bank

earthrealm:

Yeah..
Just ensure its same make and model...and same settings across board.
The grand patron of this thread Georged1 posted his setup recently, he has 3 cc abi 4 sef

PLEASE AND PLEASE I'M BEGGING IN THE NAME OF GOD DONT IGNORE
Good morning my fellow nairalanders, i'm here to seek small support from you. I borrowed 20k from somebody to satisfy my bussiness needs early this year with the hope of refunding him before april, but due to covid19 outbreak i was unable to afford such amount, right now the owner is sending serious threat to me pls i dont know were to go, i want to use this medium to appeal for help/support from my oga on top and my fellow nairalander to support me with what ever amount you can afford to help. Even #100, #200, 1k or more can go a long way. There is this say that say 'GIVERS NEVER LACK' And it shall come to pass in your life. My prayer is, what ever u do a business anything shall bear good fruit for you and you will never lack, belief and accept my prayer the miracle must surely come to pass .Pls For those of you who are willing to help here is my account number... Name-inyang ikwo essien...BANK- Fidelity

earthrealm:


Try and beat this.
3s2p 280w yingli @ noon
Total 1680w installed capacity...harvest 2035w, it even hit 2045w..but went out b4 i could take a picture.
Next step would be to verfiy this readings with a clamp meter, cos i had about 34.6amps coming in @ 57.6v or so
