nog niet in gebruik genomen, staat te wachten op een noodsituatie

Estoy muy sorprendido con la relación calidad/precio. La parte motor va sobradísima para generar 2.8kw. La tarjeta inverter es estándar para 2.8kw, pero está muy bien refrigerada. Lo he transformado a dual (gasolina/propano) y probado durante 11 horas ininterrumpidamente con una carga de 800W constantes. Ha superado mi prueba sin inmutarse.
El consumo de propano con una carga continua de 1Kw ha sido de 0,5Kg/hora.

Lo he modificado un poco: ruedas, asa plegable, carburador dual, cuentahoras con Kw...
Ha estado funcionado sin problemas y sin parar durante 11 horas alimentando 800w y lo tuve que apagar para no molestar de noche. Lo cierto es que desconocía esta marca, pero me ha sorprendido mucho y para bien, no se ha sobrecalentado el motor ni tampoco el inversor tras tantas horas en funcionamiento en el sur de España. Ya eso es un gran detalle.
Un 10 calidad precio. Por cierto un detalle técnico: Es bifásico, no monofásico + neutro.
