Industry Challenges
01
High fuel consumption of diesel genset, heavy carbon emission pressure.
02
Waste of potential energy during hoisting/lowering, severe resistor heating.
03
Conventional RTGs are noisy, disturbing port environment.
04
High diesel engine maintenance cost, frequent spare parts replacement.
INVT Solution
RTG
INVT uses PCS bidirectional converter technology with supercapacitors or lithium batteries to recover and reuse hoisting potential energy. Supports diesel engine cylinder cut-out (e.g., from 6 to 4 cylinders), reducing fuel consumption by over 30%. Optional all-electric retrofit for zero-emission operation.

Core Concept
Energy feedback + hybrid power – a green, economical, low-noise drive solution for RTGs.
Technical Claims
PCS bidirectional converter: energy fed back to battery/capacitor during lowering, reused for next lift.
Diesel cylinder cut-out: automatically deactivates some cylinders based on load power, saving fuel.
Harmonic suppression: low output harmonics, minimal interference to diesel genset and grid.
All-electric option: retrofitted with lithium battery for zero-emission operation.
Customer Benefits
01Fuel Saving
Potential energy recovery + cylinder cut-out reduce fuel consumption by 30–50%, significantly lowering annual operating costs.
02Emission Reduction
Less CO₂ and black smoke, lower noise, improved port environment.
03Lower Maintenance
Reduced diesel engine running time extends service intervals, cuts maintenance costs.
04Fast Payback
Energy-saving retrofit pays back in 2-3 years.
