PURE SINE WAVE INVERTER
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 centers and health clinics. This inverter is also a good choice for small PV systems for telecom, remote
cabins and weekend homes, and RV/caravans and boats.
The SureSine’s combination of performance, features and competitive price provides the best small inverter value
on the market. 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
anodized aluminum 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 parameters. Additional adjustability is
possible via RJ-11 to RS-232 adapter to a personal
computer and using Morningstar’s PC software.
