About Certifications
About EverVolt Certifications
Below are descriptions of some relevant certifications that the EverVolt
conforms to:
• UL 1973: These requirements cover electric energy storage systems
as defined by this standard for use as energy storage for stationary
applications such as for PV, wind turbine storage or for UPS, etc.
applications. These systems are to be installed in accordance with
the National Electric Code, ANSI/NFPA 70 or other applicable
installation codes.
• UL 1741 SA: A product safety standard that lays out the
manufacturing (including software) and product testing requirements
with the goal of producing inverters more capable of riding through
grid excursions or even actively managing grid reliability functions.
• UL 1642: These requirements cover primary (non-rechargeable) and
secondary (rechargeable) lithium batteries for use as power sources
in products. These batteries contain metallic lithium, or a lithium
alloy, or a lithium ion, and may consist of a single electrochemical
cell or two or more cells connected in series, parallel, or both, that
convert chemical energy into electrical energy by an irreversible or
reversible chemical reaction.
• UL9540: 1.1 These requirements cover energy storage systems
that are intended to receive electric energy and then to store the
energy in some form so that the energy storage system can provide
electrical energy to loads or to the local/area electric power system
(EPS) up to the utility grid when needed. The types of energy storage
covered under this standard include electrochemical, chemical,
mechanical and thermal. The energy storage systems equipment
(constructed either as one unitary complete system or as matched
assemblies that when connected are the system) may include
equipment for charging, discharging, control, protection, power
conversion, communication, controlling the system environment, air,
fire detection and suppression system, fuel or other fluid movement
and containment, etc. The system may contain other ancillary
equipment related to the functioning of the energy storage system.
1.2 The systems covered by this standard include those intended to
be used in a standalone mode (e.g. islanded) including "self-supply"
systems to provide electric energy and those used in parallel with
an electric power system or electric utility grid such as "grid-supply"
systems, or applications that perform multiple operational modes.
1.3 Requirements for installation, with the exception of installation
