24V systems aren't as common as 12V in the van and RV world, but in the right application they're the better choice. Semi-trucks, larger specialty vehicles, and high-efficiency builds benefit from 24V architecture — lower current for the same power means smaller wire, less heat, and better performance over long cable runs.
Voltara Systems designs and installs 24V electrical systems for trucks, specialty vehicles, and high-demand mobile builds in Long Beach, CA.
For the same power output, 24V draws half the current of 12V. That means smaller cable cross-sections, less heat in the wire, and less voltage drop on long runs.
Large battery banks, high-output inverters, DC split AC systems — the current reduction at 24V is significant. For semi-trucks, 24V is standard architecture.
DC-DC buck converters step down to 12V for accessories that need it. One battery bank powers everything cleanly — no separate 12V bank required.
24V battery bank configuration. Correct bus bar and cable sizing for 24V output. Branch circuit design and fusing. Integration with 24V-compatible loads and any DC-DC converters needed to power 12V accessories. Full system testing before handoff.

Yes — with a DC-DC buck converter stepping down to 12V for accessories that need it. We integrate these into the system design so everything runs from the same bank cleanly, without a separate 12V battery.
For the same power output, 24V draws half the current. That means less heat in the wiring, less voltage drop over distance, and the ability to use smaller wire for the same load. For high-power builds, the efficiency difference is real.
Yes — most quality MPPT charge controllers support both 12V and 24V battery banks. We specify the right controller for your system voltage as part of the overall design.
Let's talk about whether 24V is the right architecture.
