Hello everyone,
I was wondering if Victron sell DC-DC buck converters.
Because to use the phoenix 48/5000 I need to decrease my voltage of the battery to 38-66V.
If not have anyone then have a idea where I can buy them somewere else or to design it my self
I don't think you will find a DCDC buck converter that can deliver so much energy. The 48/5000 has a peak power of 10kW -> 150A @ 66V
Even at normal power (4kW@25°C) you need 60A @ 66V
What battery voltage do you have and why?
I have a 80 V battery wich is wanna use for powering the light.
The output of the battery is 200 A
Victron sells all types of down converters in the Orion line.
Design of a DC/DC converter to handle the power levels you're suggesting is not trivial, there's a lot of design and test that goes around picking a switching chipset and FETs.
Do you have access to a mid-point tap on the battery- you can use 2x inverters in parallel if you can rearrange your light into two independent but identical banks.
Or consider powering lights from DC if that's an option.
