Discuss 12V solar powered UV disinfection system in the Solar PV Forum area at ElectriciansForums.net

Hi everyone,

I am currently undergoing a small DIY project to make a solar-powered UV disinfection system.

The 2 loads I have are a small 4LPM 12v DC pump and a 24V 10W UV lamp.

My system consists of a 50W 12V solar panel which is connected to a 3A charge controller, A 12v 14AH battery, a 200W 12v DC to 220V AC inverter and a ballast to regulate the voltage to the UV lamp.

I was wondering if it was viable to run both loads simultaneously and how to do this? My original plan was to connect the DC pump to the load port on the charge controller and the inverter to the battery terminals, however, I am worried if this is feasible especially considering the low current rating of the charge controller.

If this is not feasible how else can I operate both loads simultaneously?

Thank you for your help
