Going from 12v to 24v

[ula]

Hi
I have an off grid 12 v system and want to up it to 24 v. My question is about the load. I have our 12v lights running off the load. the charge controller is a renogy 40 amp tracer mppt. WHat do I do about the lights coming off the load?

Thank you!

Use a 24-to-12 Volt DC-to-DC buck inverter.

Why are you changing to 24 Volts, if you have 12 volts loads?
Do you also have a 12 Volt DC to 120 Volt AC Inverter for a fridge?

Yes, step down converters come in many voltages. 24 to 12v, for standard auto/RV lights and appliances, 19v for laptops and LED TV's, and even 5 volt for USB and 7 and 9v for other electronic devices. You can even get 24 to 13.8 volts, common for HAM radio users. Just make sure you use fuses and a switch, these power converters use some power even if the connected device is turned off.

I have just done the same 4 x 100 ampHr Gell batteries was 12v now 24 running a 30amp step down converter
I mainly went to 24 to utilise a 3000 watt 24v to 240V inverter my whole shed runs 12v LED strip lighting and the refrigerator is 12\24v so no biggie
I am running an epsolar 30 amp MPPT so instead of the 330 watts of panels I can now have up to 780 Watts of panels on the roof to realy kick the charge up
not that I need it this time of year comeing into summer in Australia
