Discover Helios ESS 51.2V IP65 16kWh LiFePO4 Battery NS - 52-48-16000 - (900-0077)

Description
Overview
The Discover Helios Energy Storage System (ESS) is a high-performance 16 kWh lithium iron phosphate (LiFePO₄) battery designed for off-grid, hybrid, commercial, and microgrid applications.
Built on Discover’s long-standing battery engineering heritage, Helios combines high power output, advanced safety systems, and closed-loop BMS communication to deliver predictable, long-term performance in real-world installations.
With an IP65 outdoor-rated enclosure, integrated cold-climate heating, and compatibility with leading inverter platforms, Helios is engineered for Australian conditions and demanding system designs — from whole-home backup through to multi-battery microgrids.
Where Helios Fits Best
Helios ESS is suited to projects where power delivery, system control, and long-term reliability matter, including:
- Off-grid residential systems
- Whole-home backup solutions
- Commercial and industrial energy storage
- Remote and microgrid applications
- Hybrid systems requiring closed-loop control
Key Benefits
High Power, Real-World Performance
- 16 kWh usable capacity per module
- 10 kW continuous output
- Up to 19 kW peak power (10 seconds)
- High continuous charge and discharge current for demanding loads
Designed to support high surge requirements and dynamic load profiles often seen in off-grid and hybrid systems.
Advanced BMS & Closed-Loop Communication
- 4th-generation Battery Management System (BMS)
- Supports closed-loop communication with major inverter platforms
- Enables accurate charge control, current limiting, and state-of-charge reporting
- Improves system efficiency and extends battery life
Closed-loop operation ensures the inverter follows the battery’s limits — not the other way around.
Built for Australian Conditions
- IP65-rated stainless steel enclosure for outdoor installation
- Integrated 250 W self-heating system
- Reliable operation down to -25 °C
- Designed for harsh, remote, and exposed environments
Safety First by Design
- Comprehensive over-voltage, over-current, and thermal protection
- Dual internal fire arrestors
- Emergency stop input for Rapid Shutdown (RSD) integration
- Designed to meet modern safety and compliance expectations
Scalable & System-Ready
- Parallel up to 36 modules (up to 579.6 kWh) with closed-loop communication
- Battery-to-battery parallel cabling available
- Supports expansion as system requirements grow
Inverter Compatibility
Helios ESS is compatible with a wide range of 48 V inverter-chargers and solar charge controllers, supporting both:
- Closed-loop communication (via CAN)
- Open-loop operation where required
Commonly deployed with platforms such as:
- Victron Energy
- Selectronic
- Deye / Noark
(Exact configuration depends on inverter model and firmware.)
Included & Optional Accessories
Available accessories include:
- Battery-to-battery parallel cable sets
- Battery-to-inverter cable sets (various gauges)
- LYNK II Gateway (for advanced communication and monitoring)
- Lift handle sets for safe installation
(Accessory selection depends on system design and inverter platform.)
Why Choose Helios from DPA?
DPA supports Helios ESS as part of a system-first approach, helping installers:
- Select the right inverter-battery pairing
- Configure closed-loop communication correctly
- Avoid commissioning issues and rework
- Build systems that perform predictably over time
If you’re designing an off-grid, hybrid, or commercial system and want one battery platform that works across multiple inverter ecosystems, Helios is a strong, proven option.
