how can i make a radio communication equipments working with solar source of electric?

Question

such as HF radio euipements

can you show me your answer with a drawing picture?

Answer 1

You'll need a solar voltage source that matches one of the input voltages of the HF gear. 12 volts DC is probably the easiest voltage to match.
BUT unless your using gear that requires very little current, you'll need a good-sized solar array to power it directly ... which is why battery-power is good.

Answer 2

Get one that works on a battery. Charge the battery with solar power. Direct solar power will make it unstable and probably will break the equipment.
