The Discover Energy Systems HELIOS ESS 52-48-16000 is a 16.1 kWh lithium iron phosphate (LiFePO4) battery for residential solar energy storage, off-grid power and home battery backup. It provides 16,080 Wh of nominal energy capacity at 51.2V, with a 314 Ah rating.
The outdoor-rated cabinet combines an IP65 enclosure, built-in battery heating and an integrated battery management system. HELIOS ESS works with supported hybrid and off-grid inverters, with closed-loop CAN communication for compatible systems.
US Solar Supplier can help you confirm inverter compatibility and select the accessories needed for your battery installation.
A single HELIOS ESS battery provides substantial storage capacity for a home backup or off-grid solar system. Actual backup duration depends on connected loads, battery settings and system efficiency.
The IP65 enclosure protects against dust and water ingress. Built-in heating supports cold-weather operation within the manufacturer's installation and operating requirements.
The battery management system provides overvoltage, overcurrent and thermal protection.
Parallel installations allow additional batteries to be added as storage needs grow. Required wiring, accessories and communication equipment depend on the number of batteries and inverter configuration.

The HELIOS ESS has a nominal voltage of 51.2V and is used with compatible 48V-class inverter systems. Confirm the inverter's supported battery voltage range and communication requirements before ordering.
Yes. Its IP65 enclosure is rated for outdoor use when installed according to Discover's requirements. Installation location, mounting and clearances must follow the manufacturer manual and local requirements.
Runtime depends on how much power your appliances use. As a simple example, 16.08 kWh divided by a constant 1 kW load equals about 16 hours before accounting for reserve settings, inverter losses and other operating limits. Whole-home backup sizing also needs to account for peak loads and inverter output.
HELIOS ESS supports compatible hybrid and off-grid inverters. Closed-loop communication depends on the inverter model and required communication equipment. Contact US Solar Supplier to confirm compatibility and accessories for your system.
Yes. HELIOS ESS supports parallel battery configurations. Expansion must follow Discover's wiring and communication requirements and the limits of your inverter system.
Discover provides a five-year base workmanship warranty for the HELIOS ESS 52-48-16000. Registration with Discover within 30 days of installation extends the workmanship warranty to up to 10 years, subject to the manufacturer's warranty terms. Separate energy performance coverage and throughput limits also apply.
