Fronius and Renon Secure CEC Listing for Fronius GEN24 Plus and Renon Xtreme HV 1.0
Fronius and Renon are pleased to announce that Fronius
GEN24 Plus solar inverters (3.8-10.0 kW) and the Renon Xtreme
HV 1.0 battery energy systems (9.6, 14.4, and 19.2 kWh) have been
listed by the California Energy Commission as a paired residential storage
solution. The listing supports California installers working to reduce friction
in project permitting and interconnection, while also reinforcing that the
system meets the state’s efficiency and performance expectations.
For homeowners and installers, the result is a more confident
path to specifying a high-voltage solar + storage system built for residential
use and designed to integrate cleanly into modern PV applications. The pairing
gives solar professionals another option when they need a vetted storage
configuration that can broaden system design choices without sacrificing
reliability.
The Renon Xtreme HV 1.0 was developed to deliver high-voltage
residential storage in a compact, modular format. Its operating range of
192–384 V helps reduce transmission losses, while its stackable architecture
supports two to four battery modules and is designed to improve system
flexibility through dynamic current equalization. Built-in
smart management, Wi-Fi connectivity, an EMS, and a battery optimizer
rated for up to 8,000 cycles makes it a strong fit for homeowners seeking
long-term energy storage performance.
When a Renon Xtreme HV 1.0 is paired with the Fronius GEN24
Plus, the system supports a closed-loop DC-coupled architecture that helps
deliver efficient energy flow and dependable backup-ready performance. While
the inverter and battery manage the energy, the Fronius EBLU device acts as an
intelligent bridge to automatically transfer to backup power should a grid
outage or weather related event where there’s a loss in power would occur (see
all 3 components in the supplied picture).
Renon Smart and Renon Cloud add monitoring and management tools that
allow users to track system performance and energy production or consumption in
real time. The Renon Xtreme HV 1.0 is certified to IEC 62619, UN 38.3, UL 1973,
and UL 9540.
The Fronius GEN24 Plus brings its own set of practical
advantages to the pairing, including UP.storage compatibility, active
cooling, Dynamic Peak Manager shade management, and built-in PV Point backup
power. Homeowners can also use Fronius Solar.start and Solar.web tools
to commission and manage battery-related functions and energy optimization.
Fronius Solar.web Premium includes the Energy Cost Assistant, which
provides automated battery charging and discharging strategies based on weather
forecasts and current pricing. The inverter is certified to UL 1741 SA, UL 1741
SB, UL 1699B, UL 9540, and IEEE 1547-2018 requirements.
“California installers need options that are both
technically sound and easy to specify, and this CEC listing ensures a seamless
permitting process for installers,” said Renon USA Owner & CEO,
Paul Buckwalter. “The GEN24 Plus and Xtreme HV 1.0 pairing gives the
California market a high-voltage storage solution that is efficient, flexible,
and ready for residential deployment,” he added.
“Fronius is excited to expand our partnership with Renon
through a CEC-listed pairing that supports installers and homeowners looking
for a dependable solution,” said Chris Connell, Head of Solutions for
Fronius USA. “Together, we’re giving customers a practical pathway to
high-performance residential energy storage,” he said.
