AiON-ESS
The AiON-ESS all-in-one integrated system is a flexible, modular AC energy storage solution for 1-hour and 2- to 6-hour applications. Both models incorporate our third- generation string inverters, together with Tier-1 energy focused batteries in a single, scaleable enclosure, enabling configurations of any size for almost any application. The fully integrated, containerized system reduces upfront capital outlay and saves on site installation work
The all-in-one system is built from paralleled AC string inverters installed inside an air-cooled section of the container, together with an isolated HVAC- or liquid-cooled DC battery compartment. DC battery strings are aggregated in small groups to keep the DC bus voltage at lower, safer levels for the end customer. The system can operate from 200 VDC up to 1350 VDC, making it compatible with most current and future energy storage technologies.
- Modular Architecture – The enclosure design houses battery racks, power conversion systems, and controls in separate compartments, each with its own protection system for maximum safety and reliability. Thanks to field-replaceable kilowatt-sized string inverters, units can be replaced in minutes.
- Thermal Management – Each system includes superior thermal management, including properly sized HVAC systems and sufficient ducting to handle expected battery and external heat loads, as well as protect from moisture intrusion.
- Designed for Safety – The equipment environment includes features to ensure the safety of technicians, first responders,and other on-site personnel, including warning lights, software lockouts, safe working spaces, and fire suppression systems.
- Fleet Controller – Each system includes an energy management system (EMS) for intelligent control of energy storage and renewable energy assets. It can also easily interface with existing EMS and supports all possible operating modes from basic P/Q adjustments to fully automated energy management control.
- Augmentation – Our all-in-one systems can be simply augmented by adding new enclosures over time. The new enclosures are shipped with batteries, but typically no new string inverters. String inverters are shifted on-site from existing to new enclosures. This reduces augmentation time and maintains project power capacity.
AiON-ESS Power Series
The AiON-ESS Power Series all-in-one integrated system is a flexible, modular AC energy storage solution for 1-hour applications.
AiON-ESS Energy Series
The AiON-ESS Energy Series all-in-one integrated system is a flexible, modular AC energy storage solution for 2- to 6-hour applications.
AiON-SIS
The AiON-String Inverter System is our third generation bidirectional string inverter for energy storage and the fundamental building block of our integrated storage systems.
With industry-leading power density, the AiON-SIS inverter offers the patented ability to parallel the inverter on both AC and DC sides, making it easy to configure multiple inverters into larger units up to 3MVA. The AiON-SIS can operate from 620 VDC up to 1500 VDC, making it compatible with most current and future energy storage technologies.
Air-cooled, the AiON-SIS can operate in environments up to 55°C/131°F (with derating), making it suitable for most applications. The AiON-SIS also features optional grid-forming capability making it suitable for use in microgrid, backup power, and resiliency applications.
The modular AiON-SIS architecture comes with multiple advantages:
- Enables right-sizing of inverter systems to optimally match power requirements by paralleling multiple, independent 140kVA string inverters
- Enhances safety and reduces cost with reduced short-circuit currents due to dividing the DC bus into multiple manageable DC busses
- Enables energy and power augmentation options - AiON-SIS-based systems can be configured into multiple DC busses, which opens opportunities for flexibility and expansion
- Improves system availability through smaller inverter sizing and through ability to create smaller, independent strings of batteries and inverters on separate DC busses
- Optional grid-forming capability makes the AiON-SIS suitable for multiple applications including microgrid
