Fischer Panda 25i 400V PMS Generator: Ultra-Quiet 25kVA 3-Phase Variable-Speed Power
The gold-standard 3-phase solution for 55-80ft yachts—25kVA peak (20kW continuous) at 400V 50Hz with only 54 dB(A) @ 7m and full variable-speed iControl2 technology.
At Wave Inboard Motors, the 25i 400V PMS has become the #1 choice for 3-phase yachts 55-80ft since 2022—with over 95 units installed from Florida to the Med. Owners running high-draw equipment (large inverters, induction galleys, dive compressors, or 3-phase watermakers) love that it delivers 25kVA peak (20kW continuous) at 400V 50Hz three-phase while remaining quieter than a household fridge and weighing just 350 kg (772 lbs). If you’re replacing an old Onan 23-27MDK 3-phase, Kohler 24-28EKOZD 3-phase, or Northern Lights 25-30kW 3-phase, 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 400V PMS uses 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.

Frequently Asked Questions (FAQs) About the Fischer Panda 25i 400V PMS Generator
From 95+ 3-phase installs:
Is the 25i 400V 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 3-phase?
25-35% in typical yacht use. At 50% load it runs ~2400 rpm and burns ~4.0 L/hr vs 5.5 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 400V PMS run three 24,000 BTU air-conditioners?
Yes—full 20kW handles three 24k BTU plus watermaker/lights on 3-phase; soft-start recommended.
iControl2 and Cloud—what’s possible on 3-phase?
Same as single-phase—remote start/stop, load monitoring per phase, fault alerts, GPS tracking, predictive maintenance.
Parts availability USA 2025?
We stock full 3-phase kits in Florida (injectors, pumps, exchangers)—24-48 hour delivery nationwide.
