Greentech Lead U.S: GS Battery (USA) has introduced their
Hybrid Energy System (HES).
Equipped with 48 volts of ECO R advanced lead acid
battery technology, the integrated, compact unit addresses the most common
renewable energy storage needs in an easily installed, indoor/outdoor
cabinet.
Nine HES cabinets are in-service with 3 systems deployed
by EPRI for the Tennessee Valley Authority SMART Station Program and 6
storage-only systems deployed as part of a complete EV charge station by Oak
Ridge National Labs’ U.S. Department of Energy EV Charger trial program.
The HES unit is capable of powering critical loads and
has an optional integrated electric vehicle charger plug, level 2 EVSE.
The option of combining battery storage with PV power
generation gives the HES unit the expanded capability to operate either tied
into the grid, as a stand-alone unit or in a hybrid mode.
Rated NEMA 3R, the cabinet is built of outdoor grade
aluminum and has an eco-green power coat finish. Additional options
include an AC and a DC load centers, a PV charge controller, auxiliary heating
and air conditioning, a hydrogen sensor and fan cooling.
“Customers are initially deploying the HES systems
to store energy supplied by photovoltaic arrays and using this energy to charge
electric vehicles,” said Jeff Hires, engineering manager, GS Battery
and the HES designer.
“The option of Level 1 and Level 2 charging makes
this system ideal for locations installing a stand alone charging station at an
affordable cost,” Hires added. “Plus, remote monitoring and control are
built in making the system accessible anywhere over the internet.”
A true plug and play design, HES includes its versatility
and its potential for future expansion as the user’s needs evolve. The initial
use might be EV charging and as the user’s needs change, the HES can be
enhanced to include a UPS function, peak load shaving and even act as a
stand-alone PV plus storage system for residential and small commercial use.
