Renewable Energy Solution

SiC devices provide significant efficiency advantages in solar inverters: Lower switching losses enable higher switching frequencies (16-20kHz vs 8-12kHz for IGBTs), reducing magnetics size and cost

Lower conduction losses at light loads improve European efficiency (weighted average)

Better high-temperature performance maintains efficiency in hot climates

Reduced cooling requirements lower system cost. Typical efficiency improvement is 0.5-1% compared to all-IGBT designs. For a 100kW solar farm with 0.7% efficiency gain, annual energy production increases by ~6,000 kWh. Over 25 years at $0.10/kWh, this is $15,000 additional revenue per inverter.

Use SiC for boost stages and high-frequency applications where efficiency premium justifies cost. Use IGBTs for cost-sensitive designs.

The Oriental Renewable Energy Solution includes comprehensive grid support functions: Reactive power control - adjustable power factor from 0.8 leading to 0.8 lagging for grid stability

Voltage ride-through - continues operation during grid voltage disturbances per IEEE 1547 and IEC 62116

Frequency ride-through - supports grid during frequency variations

Anti-islanding - rapid detection and disconnection for safety

Power curtailment - remote or automatic power reduction when required

Ramp rate control - gradual power changes to minimize grid impact. These functions ensure compliance with modern grid codes and enable higher penetration of renewable energy.

All grid support functions are standard features. Configure per local grid code requirements.

Solar inverter sizing considerations: DC/AC ratio - typically 1.1-1.3:1 for optimal performance

Oversizing - inverter can be 10-20% smaller than array for cost savings

Clipping - some energy loss during peak production is acceptable if overall economics improve

Climate - hot climates may require larger inverters for same array size

Shading - heavy shading may benefit from multiple smaller inverters with independent MPPT. Example sizing - 100kW array in moderate climate: 80-90kW inverter with 1.2:1 ratio. For commercial installations, consider future expansion and select inverter with appropriate capacity margin.

Size inverter at 80-90% of array capacity for optimal economics. Contact our FAE team for detailed sizing analysis.

The Oriental Renewable Energy Solution is designed for 25-year system lifetime: Component selection - high-quality components with appropriate derating

Thermal design - conservative thermal design ensures component temperatures stay well below ratings
