Frequently Asked Questions
Technical and procurement questions about ENERGYPACK hybrid gensets.
Is ENERGYPACK a battery box plus a diesel generator?
No. ENERGYPACK is a factory-engineered true parallel hybrid. The diesel module and LFP battery share one AC bus and are coordinated by one Energy Management System (EMS). It is designed, tested and delivered as one machine — not two separate units bolted together on site.
Can diesel and battery serve the load at the same time?
Yes. That is what makes it a true parallel hybrid. The EMS can run the battery alone, the diesel alone, or both simultaneously on the same AC bus — depending on load demand and battery state of charge.
How much diesel can it save?
Same-site comparisons in Hong Kong show 40–50% measured diesel reduction, with up to 55% verified on a live tower-crane project. Actual savings depend on load profile, operating hours and site conditions. We can build a TCO model based on your specific project data.
Is it zero-emission?
In battery-only mode, there is zero local exhaust and near-silent operation. However, the hybrid system includes a diesel module, so it is not a zero-emission product overall. Battery-only mode runtime depends on load and state of charge.
What data do you need to size the system?
We need your typical load profile (kW over time), peak demand (kVA), operating hours per day, project duration, and site conditions (indoor/outdoor, temperature range, noise restrictions). If you have historical fuel consumption data from a diesel-only baseline, that helps build a more accurate TCO model.
Can it integrate with my existing diesel genset?
Yes. The ENERGYPACK battery module can be paired with your existing diesel genset, subject to interface and control review. Our engineering team will assess compatibility and define the integration scope.
Can units run in parallel?
Yes. Multiple ENERGYPACK units can run in parallel for larger sites, providing scalable power without a single oversized machine.
What compliance documents are available?
ENERGYPACK is designed to meet CE, Stage V (engine emissions), IEC 62619 (battery safety), IEC 62477 (power electronics), UN38.3 (transport safety), and IP54 (ingress protection). Certificate documents and declarations of conformity are available on request for qualified inquiries.
How does remote monitoring work?
Each unit reports operating data including fuel use, engine hours, battery SOC, energy delivered, alarms, uptime, and CO₂ estimates. Data is accessible via the monitoring platform and can be compiled into monthly customer reports for billing and ESG documentation.
How do we start a pilot?
We recommend a 60–90 day pilot on a single site. You provide the site and load data; we help size the unit and measure performance against your diesel-only baseline. If the data works, scale across your fleet. Contact us to discuss a pilot programme.
