iSeries Marine Inverter Generators
Compact. Intelligent. Future-Ready.
The iSeries marine inverter generator delivers clean AC power with maximum efficiency. Variable speed, whisper-quiet and precisely matched to modern onboard energy architectures. Engineered for leisure boats, yachts and hybrid DC AC systems where efficient power supply at low loads is essential.
The integrated PMG inverter automatically adapts charging voltage and engine speed to the current load profile. The result: up to 30% less fuel consumption, significantly reduced emissions. And operation you simply forget is there.
Why iSeries Generators?
Variable speed motor control adapts the generator precisely to the current energy demand. This reduces fuel consumption and emissions noticeably and ensures exceptionally quiet operation, even at low loads.
The permanently integrated PMG inverter delivers clean AC power with optimal efficiency. Charging voltage and engine speed are automatically matched to the current load profile – without manual input, without compromise.
Thanks to its ultra-compact design and short cable runs between generator and battery bank, the i-Series integrates seamlessly even in the tightest installation spaces. Compact enough for any installation space. Quiet enough to forget it is there.
Engineered for Professionals and Pioneers
The iSeries is the right choice for leisure boats and yachts that need reliable power away from shore and for hybrid DC-AC systems that demand maximum efficiency with minimum space requirements.
Seamless integration. Reliable performance. Engineered by Fischer Panda.
i-Series Marine Generators. Frequently Asked Questions.
The iSeries operates at 52 to 54 dB(A) at 7 metres, comparable to a quiet conversation. The variable speed system automatically reduces engine speed when power demand drops. This makes a decisive difference during low load situations such as overnight at anchor, where a fixed speed generator would continue running at full throttle regardless of actual demand.
A conventional generator runs at a constant 1500 or 3000 rpm regardless of how much power is actually being used. The i-Series continuously adapts its engine speed to match current demand. The result is up to 30% less fuel consumption, significantly lower noise levels, and cleaner AC output for sensitive onboard electronics.
The right model depends on your total power demand. Add up all loads that could run simultaneously — air conditioning, watermaker, battery chargers, cooking appliances. As a rule of thumb, plan for 20–30% headroom above peak demand. The Panda 5000i suits lighter leisure boats, the Panda 10000i covers mid-sized yachts with air conditioning, and models from 15 kVA upward are designed for demanding onboard systems. Our dealer network can help with a precise calculation for your setup.
Yes, the iSeries is specifically engineered for hybrid onboard architectures where generator, battery bank, and inverter work together. The integrated PMG inverter delivers clean AC power, and the compact design allows short cable runs directly to the battery bank, minimising conversion losses. Fischer Panda offers both generator and Marine eDrive from a single source, which simplifies integration, commissioning, and long-term service.
Under 50% load, the typical operating condition at anchor or overnight, real-world fuel savings of 25–30% are achievable. The greater the variation in power demand, the greater the advantage of variable speed operation compared to a generator running at constant full throttle regardless of actual consumption.
The iSeries is supported worldwide through an authorised dealer and service network. Maintenance intervals, spare parts, and technical assistance are available globally, an important factor for bluewater sailors planning extended passages. Technical documentation and manuals are available in our Knowledgebase.
