Fischer Panda 25i PMS Generator: Ultra-Quiet 25kVA Variable-Speed Power
The flagship of silence and efficiency—25kVA peak (20kW continuous) at only 54 dB(A) @ 7m with full variable-speed iControl2 technology for 55-80ft yachts and expedition vessels.
At Wave Inboard Motors, the 25i PMS has been our fastest-growing model for 55-80ft yachts since 2021—with over 120 units installed from Florida to the Med. Owners who run heavy loads (dual 24k BTU AC, watermakers, dive compressors, or full induction galleys) love that it delivers 25kVA peak (20kW continuous) at 230V 50Hz while remaining quieter than a household fridge and weighing just 340 kg (750 lbs). If you’re replacing an old Onan 21.5-27MDK, Kohler 23-28EKOZD, or Northern Lights 20-25kW, our marine generator installation service can usually complete the swap in 5-7 days with full iControl2 and Fischer Panda Cloud connectivity.
The Fischer Panda 25i PMS is built around a water-cooled Kubota V3800 four-cylinder diesel with permanent-magnet alternator and variable-speed iControl2 that adjusts RPM to load—saving 25-35% fuel vs fixed-speed units and dropping noise dramatically at part load.

Verdict: The Fischer Panda 25i PMS is unmatched for 55-80ft yachts needing silence, light weight, and modern features—variable speed saves 25-35% fuel and drops noise to unheard-of levels. Northern Lights and Kohler are solid commercial units, but for premium yachts where every dB and kg matters, the 25i PMS wins every time. In our 2025 installs, 94% of clients in this size range chose Panda.

Frequently Asked Questions (FAQs) About the Fischer Panda 25i PMS Generator
From 120+ installs and owner calls:
Is the 25i PMS really only 54 dB(A) at 7 meters?
Yes—independent tests and our measurements confirm 53-55 dB(A). Owners say “can’t hear it from the cockpit at anchor.”
Variable speed vs fixed—real fuel saving on 25kVA?
25-35% in typical yacht use. At 50% load it runs ~2400 rpm and burns ~3.8 L/hr vs 5.2 L/hr fixed.
Freshwater cooling—more maintenance than Paguro?
Yes—annual exchanger/impeller clean, but smoother running and no corrosion like seawater units.
Can the 25i PMS run three 24,000 BTU air-conditioners?
Yes—full 20kW handles three 24k BTU plus watermaker/lights; soft-start recommended.
iControl2 and Cloud—what’s possible?
Remote start/stop, load monitoring, fault alerts, GPS tracking, and predictive maintenance from your phone.
