I work for an IT firm and we have existing inverter and battery powering our server room.

We want to introduce solar to the system, Can someone please recommend how many solar panels and charge controllers to use and how to connect them ?

Existing system
8KVa/144V inverter
12nos 12V Batteries

thanks

I need a 130 or 180 or 200 watt panel to add to my current panel installation. Anyone with a trusted and perfectly rated panel here?

Just give me the prices and let meet to transact thanks

If na fast delivery, KieKie na number 1. He does his best to deliver within 24hrs and exactly what you requested.

Barezzi:

Be careful when adding new panels to an existing array...

For series connections, match the Imp as close as possible.
For parallel connections, match the Vmp as close as possible.

Failure to do this not only reduces the effective power of your array, but degrades
your CC's ability to track the maximum power point!

I am interested in the csun 200watt, what is your best price and please can you confirm the maximum power current and voltage for me. Cause some products rating can be wrong

codemaster2much:


What if the person is using a mppt charge controller. I initially have 2 130 watt panel {260} connected in series to charge a 200ah battery. But the highest watt I have gotten so far is 130watt 9amp and volt fluctuating between 13 and 13.9 or so.

Please what would you recommend

Barezzi:

Get a new CC and put the bigger panels on it. Connect to the same battery bank.

The mppt cc tracks the maximum power of your array.
When you mix-match panels of different ratings, the maximum power of your array will be driven by the lowest rated panel.

Connecting your 2 (130w) panels to 2 (200w) panels in series will not give you 660w.
Maximum power will be Imp of the 130w panel multiplied by the sum of the Vmp of the 4 panels.



As you can see, the 130w will pull down the bigger panels to its level.

codemaster2much:


That translate to more cable and cc cost. Feeling sad. Tot I could connect in series or parallel to solve the problem

In my hood, NEPA has been heartless to my neighbors since yesterday despite being Sallah day.
Thank God for my solar power.
Even with the recession in Naija.
This year's Sallah was interesting.
Me and my madam alone...
Solar gooood Oo.

Guys need advise, what is the best way to connect 130watt x2
And 80watt x2 to get the best power from the system to charge my battery {200ah}

DMerciful:
give more details...whats the Voc of the 130W and 80W?

codemaster2much:


80w is 21.6 while the 130watt is 22

DMerciful:
You can connect the 80W in series and the 120W in series then parallel these 2 strings...the might me a little loss due to d slight voltage difference but its pretty small. Or better still get 2 small mppt and run the two panel type separately to ur battery.

codemaster2much:


I have an mppt and a pwm I was using before... Do you think this is OK and how can I connect them.

DMerciful:
if you system is 24v inverter, PWM will not be efficient for use in the 80W series so get another small mppt. if your system is 12v, then connect the 80W in parallel with at least 10mm cables through ur PWM to your battery while the 130W should be in series through the mppt to ur battery.

codemaster2much:
it is a 12v battery system. And the 80watt is poly while the 130 is mono. Don't know where to get the 10mm cable, check both jumia and konga .

Go with this option,no need to worry yourself.
