Verified technical answer

GE SX-8000 HBT at a glance

GE SX-8000 HBT is a three-phase benzin portable generator with 7 kVA / 5.6 kW PRP and 8 kVA / 6.4 kW LTP. The values below are taken from the assigned, field-audited manufacturer datasheet.

PRP output7 kVA / 5.6 kW
LTP output8 kVA / 6.4 kW
Phase / voltage3-phase / 400/230 V
FuelBenzin
EngineHONDA iGX 390
Tank / runtime18 lt. / 7.5 h

How should the output be interpreted?

PRP and LTP describe different rated operating conditions. The connected loads, starting currents and operating duration still need to be checked.

What confirms these values?

The visible values and structured data use the same field-audited manufacturer datasheet.
