SUNFOREST: THREE PHASE CENTRAL INVERTER


Three phase central inverter with advanced system intelligence. Rapid control boost PV plant KWH yield, with DC/AC disconnected switches built-in. Famous components. High efficiency and stability.


Advanced performance

With the advanced system intelligence, highly speed MPPT technology, industrial-grade engineering and compete fault protections, Sunforest series central commercial inverters maximize system uptime and power production, even in harshest environments

DSP-controlled IGBT circuitry to achieve high efficiency, reliability and low installing cost

Sunforest KT series grid-tied inverters are integrated with an isolation transformer

Sunforest KTL series grid-tied inverters have a max efficiency of 98.6% without a transformer

Multiple work mode, SVG (Static Var Generator) mode, AntiReverse Power control mode

Optimal MPPT technology

Rapid and accurate control boost PV plant KWH yield

Provides a wide range of operation voltage

Utility-ready features

Open communication protocol, compatible with any third-party monitoring system and easily integrated into SCADA systems

Remote control of real and reactive power

ZVRT (Zero voltage ride through)

Power factor control

Simplified grid interconnection

Increased PV plant yield

Rapid and accurate MPPT control increases PV plant KWH yield by extending the production window of arrays, enabling them to operate at optimal voltage and current levels for longer periods of time-even in varied sunlight conditions to maximize efficiency and enable you to get the most from your investment
