The
SureSine inverter has been developed using
MorningStar's
power
electronics expertise and 25 years of
experience with remote
off-grid
photovoltaic (PV) systems. This product is a
pure sine wave
inverter
designed specifically to
meet the needs of rural PV
electrification
requiring AC power including Solar Home
Systems, Schools,
Community
Centres and Health Clinics. This inverter is
also a good choice for
small
PV systems for Remote
Cabins, Weekend Homes, Motorhomes and
Boats

|
The SureSine's combination of performance, features
and competitive price provides the best small inverter
value
on the marker. It is highly reliable, having no
internal cooling fan or other moving parts prone to
failure.

Key
Features and Benefits
Improved Load
Operation
¤
Pure Sine Wave - Provides quality AC
equivalent to grid power. A sine wave will
extend the life of the
household appliances (lights, TV,
fans) and improve load performance
¤ Toroidal Transformer
Design - Generates good wave form throughout
the range of input voltages
¤ Outstanding Surge Capability -
Handles a 200% surge during load start-up, to
a maximum of 600 watts
|
More Power Available
¤ High Efficiency - A
high peak efficiency will reduce heating and
make more solar energy available for
powering loads
¤ Low Self-Consumption
- The SureSine consumes 450mA while powering
loads. During no load conditions,
solar energy is not wasted
because the SureSine automatically powers down
to stand-by mode, reducing
self-consumption to one tenth of
operating consumption
|
Extremely High Reliability
¤ Extensive Electronic
Protections - The SureSine has extensive
electronic protections that will
automatically protect against
faults and user mistakes such as short
circuit, overload, high temperature
and low voltage disconnect.
Recovery from most faults is automatic
¤ No Internal Cooling
Fan - A key design objective since fans often
fail in harsh environments and are noisy,
consume power and blow dirt into
the electronics
¤ Tropicalization - The
SureSine uses epoxy encapsulation, conformal
coating, stainless steel hardware,
and an anodised aluminium
enclosure to protect against harsh tropical
and marine environments
|
Other Features
¤ More Information -
The two LEDs provide important information to
the user about system status and any
fault conditions. An optional
digital meter may be connected to the SureSine
to display additional system
information
¤ Remote On/Off -
Improves safety by making it easy to install
the SureSine in an inaccessible location or
enclosure. Reduces system cost by
avoiding the need to add an AC safety
disconnect to the system
¤ Adjustability - Four
DIP switches provide easy adjustability of
several system parameter. Additional
adjustability is possible via
RJ-11 to RS-232 adapter to a personal computer
using MorningStar's PC
software
