The Hybrid Energy System (HES) is a portable power supply that integrates with diesel generators to optimize load capacities. The use of HES to manage low loads virtually eliminates the risk of wet stacking and can cut associated generator maintenance time and costs in half. The technology also allows users to rent a smaller generator by providing temporary extra power for load spikes — for example, the surge in demand when a motor starts up. HES inverters can handle load spikes double their specified capacity.
The system features lithium-ion battery technology and automatic load level sensing, allowing it to switch power flow as needed between the generator and the HES. This includes using the generator for higher loads and stored energy for lower loads. The HES also enables the storage and use of alternative energy sources when paired with electricity-producing systems such as solar, wind and hydroelectricity. In addition, it is silent, making it ideal for noise-sensitive jobsites, events or applications.
Six models are offered with outputs from 3.7 to 60 kVA, and storage ranges from 7.5 to 120kWh. All models feature the Node ECM (Energy Control Module) 7-in. touchscreen. Node retrieves data from all connected devices including inverters, batteries, diesel gensets, PV and more. The system displays the information on the screen and uses it to inform which energy source to use and which loads to prioritize. Prism EMS (Energy Management System) software is used for reporting and business intelligence, remote asset management and customer billing. The HES range features remote generator start and remote communication, including GPS location tracking.
Users can select from three predetermined run modes. The timer mode allows operators to set the generator for constant running at times when power usage is highest. Lower power draw periods will be programmed for HES operation, running the site on stored energy. When the situation permits, the HES can be set as the primary power source and the generator will only kick in to recharge the unit’s battery. This is ideal in situations where noise is an issue or where a generator is much larger than the needed power draw. The load sensing mode enables the system to monitor power levels and automatically switch between generator and HES as the power draw demands. This mode is ideal for those applications where the power need fluctuates significantly throughout the day. This provides an uninterrupted power supply even if the generator fails.
All models include temperature control features, as well as forklift pockets and lift and drag skid lift points.
