I consider changing from 12V to 24V solar system. I know I have to have solar panels and batteries in series to get 24V. But can I use all my existing 12V leds, or do I have to change all the lights in the house to 24V as well?

You need to change anything that is rated for just 12V. That means if your charge controller is only for 12V, you need to replace that. Some are auto-sensing 12 or 24V, so check what you have. If you have an inverter, it definitively needs to be changed. 12V LEDs will need to be replaced with 24V, unless you get a 24V to 12V DC to DC converter. But that can waste electricity by being inefficient. What are you doing that is requiring you change to 12V? At some point it may be worth while to leave the existing 12V system in place and add a second one.Solar Queen

Thank you.
Maybe I don`t need to change the system to 24V anyway? The reason I was thinking of 24V was to save electricity and avoid losses in long 12V cables. But all the lights in the house are 12V, so it`s maybe just more hazzle to change all the lights...Comment

Why on earth are you using 12 volt system for your house? 12 volts is for toys and RV's. Home systems are 24 and 48 volt systems connected to an Inverter and everything in the house uses efficient AC power with small inexpensive wire.MSEE, PEComment
