5 MVA, 0.8 P.F. Container Load Bank
• Very high capacity, resistive/inductive
portable Load Bank
• 5.0MVA, 4.0MW, 3.0MVAR
• Low voltage to 690vAC
• ISO 20’ Container style enclosure
• Digital load control
The Simplex Solar-5 is a very large
capacity, resistive/inductive portable
load bank capable of 0.8 power factor
loads to 5.0MVA (4.0MW, 3.0MVAR).
The Solar-5 is designed for low voltage
application to 690vAC. PLC based
digital load control with touchscreen
operator interface is standard. The unit
is network capable with other Solar
Load Banks as well as most standard
Simplex Load Banks in order to form
large, ultra high capacity systems which
can be controlled from a single operator
interface with totalized data acquisition.
The Solar-5 is packaged in a purposebuilt, ISO 20’, high-cube container
STYLE enclosure. Rather than repurposing used ISO shipping containers,
Simplex has ingeniously designed a
purpose-built enclosure which includes
the important design features of a
container, including holding true to ISO
container dimensions, incorporating
ISO container corner locking pins and
using heavy-duty formed and tubular
steel construction in a massive, rugged
weldment. A purpose-built enclosure
eliminates the compromises inherent
in reworking a used shipping container.
The resultant enclosure provides
4-sided service access and generous
internal space while maintaining
structural integrity.
The Solar-5 is intended for severe
portable duty. As such, the unit buttonsup tight when not in use. Hot air exhaust
is vertical, through roof mounted
electrically operated louvers. Air intakes
are on the side and covered by manual
hatches. The load bank is also suitable
for stationary application.
Two means of power connection are
provided: copper bus bars for bolt-on
cables, and Cam-Lock type connectors
for Cam-lock type terminated cable.
The Solar-5 is equipped with the
advanced Simplex Digital Control
System which provides touchscreen
operator interface, keypad load entry,
data display and acquisition, Ethernet
remote control. The load bank is
equipped with a local operator interface
which is removable for remote control.
Software is available for control from
a user supplied Windows PC. Simplex
AutoTest software is available for full
testing automation.
