Solar + Generator Synchronization
PowerProKe Ltd specializes in Synchronous Integration—the art of making solar PV and diesel generators work in perfect harmony. We use industrial-grade controllers to ensure zero-millisecond power transfer and massive fuel savings.
The 3 Pillars of Sync Stability
Integration is not just a cable connection. It's a sophisticated electronic handshake between stable mechanical power and volatile solar DC yield.
Frequency & Phase Match
Our controllers monitor the 'Gen-Wave' and ensure the solar inverter's AC output matches the alternator's phase angle perfectly before closing the breaker.
Active Load Management
The system regulates the 'Fuel Rack' of the generator. As solar production peaks, the generator's throttle is electronically eased to save every drop of diesel possible.
Reverse Power Guard
Critical Protection. Our integration uses bidirectional meters to ensure solar energy never flows back into the generator windings—an event which can cause total engine failure.
Notice to IPPs & Facility Managers
Traditional 'Off-the-shelf' solar inverters are often unable to sync with diesel generators due to the high impedance of the alternator. PowerProKe Ltd uses Voltage-Source Inverters (VSI) specifically tuned for Kenay's industrial generator brands like Cummins, Perkins, and Caterpillar.Request a Compatibility Test.
The Integration Stack
Our hardware-agnostic controllers bridge the physical and digital gap between different power sources.
Remote Telemetry Monitoring
Track fuel levels, battery SoC, and solar production in real-time from a central dashboard or mobile app.
Dynamic Load Balancing
The system sheds non-critical loads (e.g., HVAC) during low solar irradiance to avoid starting the generator unnecessarily.
Power Quality Regulation
Harmonic filtering ensures that the 'dirty' power sometimes produced by cheap solar components doesn't damage your generator.

Control Systems
The 'brain' of any hybrid system is the controller. We use industry-standard synchronization modules that are trusted by utility grids worldwide.
DeepSea & ComAp Integration
Full digital integration with DSE 8610 or ComAp IG-NTC controllers to ensure perfect phase synchronization between the inverter and the alternator.
Modbus/TCP Communication
High-speed data bus connectivity allows the solar system to request 'Active Power Support' from the generator during heavy motor starts.
Integration Modes
Fuel Optimization Mode
The system pushes the generator to its 'Minimum Load' (typically 30%) and uses solar to carry everything else, reaching maximum fuel efficiency without engine glazing.
Spinning Reserve Mode
The generator stays in 'Ready-to-Start' or 'Idle Sync' to protect critical servers or medical equipment during volatile cloud cover.
Massive Fuel Reduction
Most Kenyan businesses run generators for too many hours. Integration reduces generator runtime by up to 75%, leading to immediate OpEx savings.

Maintenance Cycle Extension
Guaranteed Power Quality
Our systems ensure voltage THD (Total Harmonic Distortion) stays below 5%, protecting sensitive medical and data hardware.
Instant Fault Detection
AI-driven predictive maintenance detects battery cell failure or generator air-locks BEFORE the power cycle starts.
Integration FAQ
Addressing technical queries for plant engineers and facility owners.
Can I integrate solar with an older mechanical (non-electronic) generator?
Yes. While electronic generators are easier to control via ECU communication, we can integrate older mechanical units using 'Frequency Droop' control. This requires a stable Governor and a reliable AVR (Automatic Voltage Regulator). We may recommend an AVR upgrade if yours is unstable.
What is 'Minimum Load Enforcement' and why is it important?
Running a diesel engine at very low load (below 30%) causes 'Wet Stacking' or glazing of the cylinder walls. Our smart controllers ensure the generator always stays above this threshold, or triggers a 'Flush Cycle' to protect the engine while maximizing solar use.
Is there any risk to my generator's alternator?
If not properly protected, yes. That's why PowerProKe Ltd installs multi-level protection relays that trip the solar system instantly if any reverse power or severe harmonic distortion is detected. Your generator remains the priority asset.
Will this integration affect my generator warranty?
We use non-intrusive controllers that read data from the generator's existing communication ports (J1939/CANBUS). Since we aren't tapping into the engine circuitry directly, the manufacturer warranty typically remains intact. We can coordinate with your brand dealer like Mantrac or Car & General if required.
