Morningstar Introduces Two New Product Innovations at Intersolar Europe 2013 / The TriStar MPPT(TM) 600V charge controller and the Ground Fault Protection Device

Newtown, PA, USA (ots) - At this year's Intersolar Europe
conference in Munich, Germany (June 19-21) Morningstar Corporation
unveils the new TriStar MPPT(TM) 600V charge controller
(TS-MPPT-600V) and Ground Fault Protection Device (GFPD) product line
families.

Morningstar launched the TriStar MPPT Controller family in 2009.
This line of MPPT controllers has become the world's leading MPPT
solar controllers. In fact, Morningstar's TriStar MPPT Controllers
are operating in a myriad of off-grid residential, commercial and
industrial photovoltaic (PV) installations around the globe. "The
TS-MPPT-600V builds on previous application experiences and our 20+
years of power electronics engineering excellence, to deliver the
best controller solution for stand-alone or back-up system
installations," said Lee Gordon, President & CEO, Morningstar
Corporation. "The TS-MPPT-600V uses advanced power electronics to
efficiently convert up to 600 Voc (open circuit voltage) PV for 48 or
120 Vdc battery systems." Its high voltage capability and flexible
design also means several typical application scenarios are now
possible including:

- Off-grid PV systems greater than 150 Voc with long wire runs
(from the array to the controller)

- New installation grid-tie PV systems with battery back-up

- Retrofit grid-tie PV systems with battery back-up

- Small wind (off-grid or grid-tied) with battery back-up

Morningstar's TS-MPPT-600V:

- Delivers the industry's best-in-class power efficiency.

- The TS-MPPT-600V features an advanced internal processor and
utilizes Morningstar's patented TrakStar(TM) Advanced Maximum Power
Point Tracking Technology to harvest the maximum power from the solar
array's peak power point under all operating conditions. This
high-speed processing technology and sweeping methodology enables the
TS-MPPT-600V to sweep from the battery voltage to the Voc of the
array faster than any MPPT charge controller on the market
today-faster than 1/10th of a second.

- Uses Morningstar's patented 4-stage charging algorithm to
optimize battery health.

- Features extensive system networking, monitoring and
communications.

- Is environmentally optimized and equipped with extensive
electronic protections.

- Offers superior lightning protection (from nearby
lightning-induced voltage and current spikes).

- Is engineered with a robust thermal and mechanical design to
deliver the highest reliability and excellent performance.

The Ground Fault Protection Device (GFPD) products are built to be
both off-grid and on-grid PV safety devices. The GFPD is available in
two model variants (GFPD-150V & GFPD-600V) to support 150V and 600V
PV system breaker stacks. The Morningstar's GFPD increases safety and
design flexibility in off-grid and on-grid PV systems. Ground-fault
protection is used in electrical systems to prevent current from
following any unintended paths during a ground fault. It is critical
to detect any stray current and to interrupt (break) the circuit
until safe operation can be restored. Any current imbalance between
the sides of a circuit indicates a ground-fault. Morningstar's GFPD
will detect this condition and break the circuit on both the positive
and negative legs. Disconnecting both poles ensures interruption of
the ground fault current.

Morningstar's GFPD:

- Works like traditional AC GFI.

- Maintains the integrity of earth bond for battery and loads.

- Trips at lower fault current.

- Breaks both conductors in the faulted circuit and completely
isolates PV source circuits.

- Does not require an extra warning label(s) at the battery bank
(as per U.S. National Electric Code (NEC) requirements).

- Provides design flexibility to meet a wide range of
configurations:

- Positive and negative ground.

- Large and small arrays alike.

- Makes it easier to locate and troubleshoot ground faults.

- Is powered via the PV system's battery bank.

- Is equipped with both visual and audible alarms.

- Is built to support both single controller and multiple
controllers systems:

- When the Earth bond is not broken Morningstar's GFPD will only
shut off affected controller(s).

- All Loads will continue to operate safely with the battery
remaining bonded to ground.

- Multiple controllers and GFPDs can be added on an as-needed
basis.

Morningstar's products are built from the inside out and deliver
more than twice the industry average in operating life. Morningstar's
TriStar MPPT Controllers are the ideal choice for residential,
industrial and small commercial installations. They offer a highly
efficient power path for charging batteries with high-voltage
strings, thin film and other grid-tie PV modules. We invite you to
come to our Booth B4.416 to check out our newest products.
