Peace be upon you. Perkins generator 127 kVA, meaning 100 kW. Operating hours: 5000 hours. It's been with me since new, praise be to God. Maintenance every 250 hours with changing all filters and washing. The generator is clean and new, it hasn't needed maintenance even once. Reason for selling: The size is large. I only need a 40 kW one because the work that required high electricity has finished.
