Want help in making 48v system

[djhassoonew]

Hello,

Please help me in making 48v off grid system.

I have...

Solar panels 12v-150w * 12pcs

Controller PWM 48v-60A * 2pcs

Inverter 48v-5000w * 1pc

Battery 12v-200Ah * 6pcs

Please tell me how to make connection.

Thank you

Here is a sample to get you started.

Without knowing the specs on your PV panels, I can't advise any further, except that with that large of a system, you
would benefit and save money on copper wire, by using a MPPT controller.

Also, 6, 12V batteries - you can only use 4 batteries in a 48V system. Sell the 2 batteries and the PWM controller and get a good, name brand MPPT controller

Panel specification is:

Pm:150w
Vmp:17.56v
Imp:8.54A
Voc:21.96v
ISC:10.25A

There is no way that 6 batteries can b connected to 48v system?

Sure if they were 8 volt batteries wired in series. But you have 12 volt batteries which means groups of 4 wired in series. Loose two batteries and the PWM controller. Replace the controller with a 40 amp MPPT controller.

FWIW 1800 watts on 200 amp hour batteries is going to cook the batteries. Make sure you have plenty of distilled water on hand.

How about 12v solarpanels 12pcs into 48v?

Is it ok if I use 1 pc of 48v-60A controller? If PWM is only option

You are missing the point.

First off you can't build a 48volt battery system using 6 x 12volt batteries. You can build a 24volt system with 3 sets of 2 batteries. Which gets you a 24volt 600Ah system.

Next the charging amps for your battery system needs to fall between C/8 and C/12 where C = total Ah of system. So for that 600Ah system you need between 50 and 75amps of charging or say 60amps.

You might be able to connect 12 150watt panels to that PWM charge controller but without knowing what it is I am only guessing. Based on what the max VDC input rating of that CC will determine how many of those panels you can wire in and if that will add up to around 60 amps.
