Diesel and battery,
at the same time.
Johank ENERGYPACK is a factory-engineered hybrid genset for temporary power, rental fleets and low-noise sites.
Compact hybrid,
one-truck deployment.
The KCG300E-POWER fits inner-city sites, events and telecom backup. Same EMS, same HMI as the 600 kVA flagship — sized to where you actually work.
Self-powered light,
where you need it.
The KCL2000-LED delivers 2000 W of LED brightness on a 4.5 m mast, with onboard diesel or petrol genset. One person, five minutes, light up to 150 m.
Hybrid power and mobile lighting, from one supplier
Two ENERGYPACK hybrid gensets and the KCL2000-LED light tower. All three deploy on the same trucks, with the same operators, to the same sites.
KCG600E-POWER
600 kVA / 522 kWh LFP for tower cranes, heavy plant and main-stage events.
KCG300E-POWER
300 kVA / 260 kWh LFP for inner-city sites, events and telecom backup.
KCL2000-LED
2000 W LED on a 4.5 m mast with onboard genset. Diesel or petrol, 3–5 kW.
Why fleet operators choose Johank
One supplier. Field-proven equipment. Data your customers can use to win contracts.
Measured fuel savings
ENERGYPACK delivers 40–55% diesel reduction vs same-site baseline. Light towers replace mains cable runs and standalone generators.
Field-proven, not a pilot
In service across Hong Kong construction sites and live events since December 2024. We know what goes wrong in the field — and we have already fixed it.
One supplier, one workflow
Hybrid gensets and light towers from the same factory. Same warranty terms, one phone number for support, one delivery, one invoice.
Built for fleet operators
Single-point lift. Familiar HMI. Branch training in one day. Open control protocol integrates with your existing diesel fleet.
Equipment packages, sized to your site
Each solution combines the right hybrid genset(s) and light towers for that site type. See what's recommended for tower-crane sites, festivals, telecom and more.
Construction & Tower Crane
Diesel wastes fuel at low load. Battery carries the night shift. One lift, one connection.
Build a TCO model → Rental Fleet ROI
Create a premium rental category. Data reports prove fuel savings. Branch training takes one day.
Request fleet briefing →
Events & Film
Low-noise battery mode during sensitive hours. Stable power for production. Fewer fuel deliveries.
Plan event power →
Weak Grid & EV Charging
Peak shaving for grid-constrained sites. Temporary EV charging support without grid upgrade.
Discuss project load →
Telecom & Remote
Fewer truck rolls. Quieter operation. Remote monitoring and alarms. Reliable backup power.
