VETHY / FLEET AND OEM BUYER GUIDANCE
Match the power architecture before connecting a generator.
A refrigerant such as R410A does not determine whether an air conditioner can be connected to a generator. Electrical compatibility depends on the unit supply requirements and the approved generator, charger or conversion arrangement.

Draw the actual power path
Identify the generator output, distribution equipment, charger or converter, battery and AC unit. A generator output and a 12V or 24V DC appliance are not automatically a direct connection.
Have the responsible electrical specialist review the complete arrangement against each equipment manual. This guide does not provide a wiring or conversion procedure.
Specify loads and operating modes
List the AC unit and every simultaneous load, including charging demand. Record the intended cooling mode, operating duration and starting battery reserve. Confirm which equipment remains available when the generator stops.
Do not size the supply using cooling capacity in watts. Cooling output is heat removal; it is different from electrical input.
Check controls and protection together
Request the approved operating limits and protection arrangement, including how source changes and charging modes affect the appliance supply. A nominal voltage label is only one part of the review.
Follow the generator manufacturer’s siting and exhaust instructions. This page establishes no VETHY generator package, automatic-transfer feature or fleet test result.
Submit a complete system enquiry
Send the proposed equipment list, power diagram, unit voltage and operating schedule. Ask who accepts responsibility for integration and commissioning.
See 12V electrical planning and the technical RFQ checklist for the information to collect.

FROM SELECTION TO A DEFINED PROJECT
Bring the vehicle brief.
Share the truck model, voltage, operating climate, installation photos and intended quantities. VETHY can review the proposed configuration and the evidence needed for your application.
