Selecting Appropriate Lightning Arrester

[Ferdinand Perillo]

I am confused on how to select appropriate lightning protection on my Off-grid power system.

My power system is conjoint in one pole together with a load that is connected in dc power source which is the solar panel and wind turbine.

These are the devices that is connected on the power source:

*2pcs of 300W 36V Solar Panel @ 600W Configuration

*1pc of 500W 24V Wind Turbine

*1pc of 24V Wind and Solar Hybrid Charge Controller

*12pcs of 12V 200Ah Battery @ 24V 600Ah Configuration

And here are the loads that I will going to use along with their DC-Rating

*antenna - 8.5W max consumption, power supply is 24V 0.5A PoE adapter

*camera1 - 10W, 5V 2 A adapter

*sensor1 - 216mW, 12V 1A adapter

*sensor2 - 180mW, 12V 1A adapter

*RTU1 - 6W, 12V 2A Adapter

*RTU2- 4W, 12V 2A Adapter

*IP Phone - 12W. 12V 2A Adapter

*Amplifier - 200W 12V

*Router Board - 3W 12V

My question is....

What are the basis on selecting appropriate dc lightning arrester on the power system?

How many lightning arrester am I going to use with this kind of setup? (if it is conjoint in one outdoor pole together)

Thanks in advance
