|
Powerful
inverter/charger for stand-alone or grid back-up operation which can be
stacked in clusters for high power levels in both single and three phase
networks.
High power
(up to 6.5kW for 30 min); high efficiency (> 95%); low standby & idle
consumption (25W/4W).
Designed for
rough ambient conditions. OptiCool system gives high power in
temperatures up to 40ºC by cooling the encapsulated transformer but
keeping air ventilation away from coated circuit boards & electronics
to ensure high protection for humid or salty atmospheres.
Includes two
free programmable relays per unit to enable load shedding or other use
and timers to enable daily, weekly, or monthly functions.
Integrated
MMC/SD memory card reader to enable updates, transferring of parameter
settings, for storing error/events lists , or data logging.
In stacked
cluster or multi-cluster systems all settings are made at the main unit
which gives automatic setting of parameters in slave units allowing easy
programming and update.

Sunny Island Accessories
 Gen-Man
Allows generators with more than 2-wire start to be
interfaced with 2-wire start inverter control. Controls warm-up &
cool-down times of the generator.
Product Code:
SI-GENMAN
Battery Fuse Case
Double pole fused disconnectors. These protect the cables from the
batteries and allow easier maintenance of the inverters and simplify
installation.
Product Code: SI-BATCASE.01 etc..
Frequency Shift Power Control (FSPC)
In a Sunny Island system if wind or solar
generation exceeds the power required by the loads the battery will
become fully charged.
To prevent the battery overcharging, the
Sunny Island increases the grid frequency slightly. The Sunny Boy and
Windy Boy inverters are set to 'Off grid' mode so that they can respond
to this frequency increase and back off their power generation.
In addition, to make use of this surplus
power, DILC's and Smart Loads detect this frequency change
and can be included to automatically control opportunity loads such as
heaters by switching them on only when the battery is full.
Distributed Intelligent Load Controllers (DILC's)
Product Code: LDC-2P
 Distributed
Intelligent Load Controllers ("DILC's") are designed to improve the
reliability and efficiency of isolated power systems by controlling some
of the loads on the system. When a number of load controllers are
fitted to suitable loads, each one continuously monitors the condition
of the supply and makes its own decisions on whether it should switch
its load off or on. The combined result is smoother loading on the
generators, and maximum use of available energy. Ideal for use in
Sunny Island Inverters.
 When
used as 'Load Adders' they are perfect for use in combination with
Sunny Island inverter systems - especially those incorporating wind
turbines. In periods of high wind as the battery becomes full the
Sunny Island causes grid frequency to rise. The load controllers
can detect this and switch on loads such as heaters so excess energy is
usefully deployed.
Data Sheet
Smart Loads Product Code:
SL-6000
 The Smart Load
is the ideal addition to unregulated power generators in stand-alone
grids, for example, small wind energy systems equipped with passive
stall power control.
In the event
of an electricity surplus, the Smart Load feeds the surplus to special
loads, for example, heating cartridges in a hot water tank.
The energy quantity at which the Smart Load automatically switches on
can be freely programmed using the grid frequency. This continuous
and rapid power extraction is a unique function that provides optimum
protection for the system components and ensures added reliability.
Smart Loads can be combined and operated in parallel. The Smart
Load SL 6000 can be installed as desired in either single or 3 phase AC
coupled stand-alone grids.
