[RE-wrenches] Telecomm Power Supply - Voltages

[Mark Frye]

My equipment has both 12 V and 24 V each at about 60W.

I was planning to run a Prostar at 24V and then use a DC DC converter for the 12 V load.

That looked like 2 x 285 AH AGM and 2x 320 W PV.

Now I have to go to a darker place and may have to double the battery and the PV.

That would mean I could run a Tristar at 48V and have a two DC DC converters, one for the 24V loads and one for the 12V loads.

Somehow it makes sense to me to run the supply side at 48V for lower currents and more battery cells even if it means an additional converter on the load side.

Any thoughts one way or the other?

Thanks,

Mark Frye
