TP-P8 should be selected as part of the complete tethered UAV power chain, not from the kW rating alone. TethPower reviews the aircraft battery/DC-bus voltage, continuous and peak demand, payload, tether length, cable voltage drop, operating altitude, temperature and ground-power architecture before confirming a matched configuration.

Answers to common compatibility, configuration, quotation, and delivery questions.
TP-P8 is designed for higher-power UAV platforms using a 60V-class electrical architecture. Aircraft voltage limits, payload and available lift capacity must be confirmed before integration.
No. The manual specifies 134A rated current and 150A maximum current.
The current manual states an 8kW rated output but does not specify a separate peak-power value. TethPower therefore does not publish an inferred peak rating.
Higher tether voltage reduces transmission current for a given power level, which helps control cable loss and cable weight over longer runs.
It can be evaluated for heavy-payload missions when the aircraft voltage, propulsion power, payload, tether load and environmental conditions are all compatible.
