Stap dowm transformer

[Bendesa1962]

Hi all,

I've a battery bank of 48 Volts and total 500AH = 24 kWh.

The battery bank is connected to an 3000/48 volts Watt Outback inverter that gives AC Power.

I also want to power a 12V light network in the house. So I want to install a stepdwon transformer that transforms 48V to 12V

I can buy a transformer that gives me the following specs:

Input 48V
Output 12V
Current 20A

What worries me is the 20A. Will that be ok for the purpose I want to use it?

Many thx for participating

Kind regards

Ben

I do 24v to 12v via 5a unit. It has been running for over ten years.

You just need to work out the current draw of the system you are going to install then buy the size unit you need.

Thx for your reply. 5A x 12V is only 60 Watt right? So maximum load is only 60 Watt?

Yes, I only have a some bedside lights on 12v.
