Five standard planning classes plus larger containerised / parallel pathways.
POWER & ENERGY SYSTEMS · TECHNICAL CENTRE
Specify the generator around the load, duty, destination and operating environment.
This Technical Centre brings together the current documented RHELGAN planning framework. It is designed for feasibility, procurement and project briefing. Final generator ratings, component schedule, emissions, certifications, derating, noise, corrosion protection, switchgear and warranty are confirmed against the exact quoted configuration.
Frequency, voltage and phase selected to the destination.
AMF, remote start and monitoring pathways.
Final cooling and derating remain model-specific.
Technical topics
Current specification framework.
Use these topics to structure the technical brief. Each item separates documented capability from details that still need to be fixed for the live project.
Prime vs standby ratings
Use the project duty to select the rating basis rather than treating prime and standby kVA as interchangeable.
- Reference POWER pages show both prime and standby ratings where documented.
- Prime-duty projects can involve long daily run hours and should be reviewed around the actual operating profile.
- Standby duty is not a substitute for continuous or prime operation.
- Final rating basis is confirmed on the quoted factory datasheet.
50 Hz, 60 Hz, voltage & phase
Electrical configuration is selected to the destination country, local grid and connected system.
- 50 Hz and 60 Hz configurations are available.
- Voltage and phase are selected to the destination and application.
- Single- and three-phase arrangements are available where technically applicable.
- Earthing, neutral switching, protection and connection remain project-specific.
Engine & alternator options
Use internationally supportable components where project serviceability or client specification requires them.
- Current reference POWER classes use Perkins engines in the documented 50 Hz planning family.
- The manufacturing source has documented access to genuine Perkins engines for generator-set production.
- A brushless AVR alternator with 100% copper windings is available as the standard manufacturing option.
- Genuine Stamford and Leroy-Somer alternators are available when specified.
Controls, AMF & ATS
Backup power depends on the control and transfer architecture as much as the generator itself.
- Deep Sea DSE7320 is available for AMF / auto-start applications.
- Automatic transfer switchgear is available across project sizes.
- Remote-monitoring pathways can be configured through selected controllers.
- ATS rating, neutral switching, earthing and commissioning are matched to the actual electrical system.
Parallel & containerised systems
Larger projects can use multi-set synchronisation, staged capacity and transportable generator plant modules.
- 20 ft, 30 ft, 40 ft and 40HQ container pathways are shown in the current technical material.
- Deep Sea, ComAp and DEIF synchronisation pathways are available in the manufacturing control architecture.
- Integrated and remote-radiator arrangements are available.
- External fuel connections, automatic fuel filling and water-separating filtration options are available.
Fuel, tanks & runtime
Fuel autonomy should be selected from outage duration, operating duty, refuelling access and site logistics.
- Standard base-tank arrangements are provided on the reference generator configurations.
- Extended runtime can be achieved through larger or external fuel systems.
- The current silent-system pathway includes 12 / 16 / 24 / 48-hour custom planning options.
- Bunded or externally stored fuel requirements are confirmed against the project and local rules.
Ambient temperature & altitude
High heat and altitude can reduce available engine output and change cooling requirements.
- The technical catalogue uses a 40°C radiator baseline and identifies a 50°C radiator option.
- A 50°C cooling package does not mean every engine keeps full rated output at every altitude and temperature.
- Final ambient and altitude derating is confirmed for the selected engine and radiator package.
- Ventilation and heat rejection are checked for silent and containerised installations.
Tropical, dusty & coastal projects
Environmental protection is selected around the actual site rather than applied as a generic 'tropical' label.
- High-ambient cooling and enhanced filtration can be selected for hot and dusty environments.
- Enhanced-corrosion packages can be specified for humid and salt-air exposure.
- Selected silent packages use IP65 control / distribution enclosures in the current manufacturing material.
- The exact coating system and corrosion package remain project-specific until confirmed on the quotation.
Solar + battery generator integration
The generator can operate as the resilience layer inside a separately engineered PV / battery system.
- Dry-contact remote start and Modbus RTU / RS485 integration pathways are available.
- Electronic-governor configurations can be selected where hybrid controls require them.
- SOC-based start / stop, minimum run-time and minimum-load logic are set by the project controls.
- Battery, PCS / inverter, EMS and solar-array design remain separately engineered and verified.
Factory testing, handover & evidence
Release evidence should be tied to the exact generator configuration rather than a generic catalogue claim.
- Factory load testing is available as part of the manufacturing pathway.
- Project FAT requirements can be defined before production.
- Final certification, Declaration of Conformity, test records and datasheets should match the quoted model.
- Commissioning, local electrical testing and site integration responsibilities are confirmed in the written scope.
Service & spare-parts planning
Remote power projects need the maintenance plan defined before shipment.
- Use internationally supportable engine and control components where serviceability is a project priority.
- Recommended initial service parts should be selected against the exact engine and operating hours.
- Remote programmes should consider commissioning spares, routine service kits and critical replacement parts.
- Warranty and local service arrangements are confirmed against the selected engine, destination and supplier scope.
Reference generator family
Known 50 Hz Perkins planning configurations.
These are useful starting references only. A destination-specific unit can use a different engine, alternator, dimensions, tank or electrical configuration.

|---|---|---|---|---|---|
| RHELGAN POWER 30 | 28 kVA / 22 kW | 30 kVA / 24 kW | Perkins 404D-22TG | 7.1 L/h | 115 L |
| RHELGAN POWER 60 | 60 kVA / 48 kW | 66 kVA / 53 kW | Perkins 1103A-33TG2 | 14.6 L/h | 135 L |
| RHELGAN POWER 150 | 135 kVA / 108 kW | 150 kVA / 120 kW | Perkins 1106A-70TG1 | 30.28 L/h | 210 L |
| RHELGAN POWER 300 | 275 kVA / 220 kW | 300 kVA / 240 kW | Perkins 1506A-E88TAG4 | 60.2 L/h | 770 L |
| RHELGAN POWER 500 | 438 kVA / 350 kW | 500 kVA / 400 kW | Perkins 2206A-E13TAG6 | 75 L/h | 770 L |
Remote-project spares
Plan maintenance before the generator ships.
Exact part numbers are model-specific, but the project can define the service-kit structure before final selection.
Commissioning spares
Initial consumables and small critical items selected for delivery, installation and first-start support.
500-hour service kit
Routine filters and consumables matched to the exact engine and maintenance schedule.
1,000-hour service kit
Expanded service parts for programmes expecting higher annual run hours or difficult logistics.
Remote-project critical spares
Project-selected sensors, belts, hoses, relays, filters and other downtime-sensitive items for remote or island sites.
Evidence control
Do not treat a website value as the final project guarantee. The released factory datasheet, engine data, alternator data, control schedule, test records, drawings, certifications and quotation for the exact configured set take precedence.
