Engine Glazing
At low temperatures, unburned fuel and oils accumulate on cylinder walls, preventing proper lubrication and shortening engine life.
HYBRID GENERATOR SYSTEMS
Redefine Efficiency with Hybrid Generator Systems
Reduce your fuel costs by up to 80%, minimize maintenance requirements, and enjoy maximum reliability.
The Root Cause of Inefficiency:
The Low Load Problem
Generators are sized for peak loads; however, they spend 85–95% of their operating time at only 5–15% capacity.
- Efficiency peaks at 80–90% load (~30%).
- At 10% load, efficiency drops to around 10%.
- You get 4 times less energy from the same fuel.
Low load does not only consume fuel, it also wears out the generator!
Increased Maintenance Needs
A generator running 24/7 requires service every 500–1000 hours (approximately every 6 weeks).
Higher Emissions and Noise
Inefficient combustion means more harmful exhaust gases and continuous disturbing noise.
Poor Power Quality
Engines operating at low load can become unstable, leading to voltage and frequency fluctuations.

Let the generator charge your batteries while producing power
In a hybrid system, the roles change. The inverter and battery bank provide uninterrupted power 24/7. The generator operates only when needed, running for a short time at its most efficient point to charge the batteries, then shuts down.

Beyond Fuel: Total Operational Advantage
Extended Generator Life
Prime-load operation reduces glazing and extends TBO duration.
8.5x Less Maintenance
Since operating hours are reduced, service intervals are significantly extended.
Silent Operating Periods
The generator remains off for most of the day, preserving nighttime silence.
Uninterrupted and Clean Power
With inverter support, stable power without fluctuations is supplied for sensitive loads.
The Four Golden Rules of a Successful Hybrid System
Generator ≥ Inverter
The generator power (kVA) must be greater than or equal to the inverter power. The most important rule.
Peak Load Capacity
The inverter must be capable of handling sudden peak loads on its own.
High Discharge Current
The battery bank must provide the C-Rate required to meet the inverter’s peak load demand.
Symmetrical DC Cabling
In parallel systems, DC cable lengths and cross-sections must be exactly identical.
From Single-Phase to Three-Phase: Power That Grows with Your Needs
The system is modular. It can start with a single unit and easily be expanded up to massive systems of 75 kVA single-phase or 225 kVA three-phase.
Unlike generators, inverter-based three-phase systems can handle unbalanced loads between phases seamlessly. This is a major advantage in real-world applications.
Practical Approach:
System Sizing in 3 Steps
Follow these logical steps to design the right system. It all starts with understanding the load.
1
Load Analysis
Determine the customer’s total daily energy demand (kWh/day) and the highest instantaneous power demand that may occur simultaneously (kW peak). This is the most critical step.
2
Battery Capacity
Calculate the required usable energy amount according to the desired autonomy period (generator-free operating time). Divide by the depth of discharge (DoD) to find the capacity.
3
Inverter Selection
The inverter power must always be greater than the determined highest instantaneous power demand (kW peak). Take into account temperature-related power derating (20% safety margin).

Frequently Asked Questions
Why is low load harmful?
At low load, combustion efficiency decreases, fuel consumption increases, and deposits build up inside the engine. This creates both cost and maintenance pressure.
How is battery autonomy calculated?
The total kWh capacity is determined by evaluating daily/hourly energy demand, target uninterrupted operating time, DoD, and safety margin together.
Is the installation modular?
Yes. The system can start with a single unit and grow through parallel expansion as demand increases.
Does the generator run all the time?
No. In a hybrid structure, the generator only starts when needed, charges the batteries, and shuts down again.
How does it perform with unbalanced three-phase loads?
The inverter-based architecture manages unbalanced phase loads more flexibly and safely than conventional generators.
How can I verify fuel savings?
Daily/weekly fuel, operating hours, and savings data can be clearly monitored through the reporting modules in the remote management portal.
