I've started deploying a DC based power system in my house. Its solar based and started as a hobby but works really well. I've got lights and USB chargers running off this system successfully for over a year now. I'm looking to expand this into other areas of the house. The USB devices when turned on cause a short voltage drop so I'm thinking about putting a capacitor over each of them to bridge the gap. The question becomes :- is it worth doing this and how do I determine if and what kind of discharge system is required. I don't want to waste power if I can help it, i.e. discharge resistors quietly consuming current. The rooms have a wall mounted outlet BTW, so there is potential for someone to touch the plug pins when they unplug something.
Basic specs: 24V system, typical voltages at device is 25-28V. Current usually 0.5-1 Amp but the four port USB devices I run could technically get to something like 3 amps. Lamps don't appear to do a huge voltage drop when flicked on.
Any help or opinions welcome :)
