10kW 96V Single-Phase Low-Frequency Off-Grid Solar Inverter Charger

1. Integrated Off-Grid Inverter Charger

This 10 kW single-phase low-frequency inverter charger combines pure sine wave power conversion, utility charging and MPPT solar charging in one cabinet system. The MPPT-equipped configuration is designed for compatible off-grid, standalone solar and backup-power systems using a 96 V DC battery bank.

2. 10 kW Pure Sine Wave Output

• 220 V AC Output: Provides regulated 220 V AC output with ±5% voltage tolerance.
• 50/60 Hz Operation: Supports compatible 50 Hz and 60 Hz electrical systems.
• Pure Sine Wave Supply: Provides pure sine wave output with total harmonic distortion below 3% at full load.
• Low-Frequency Transformer: Uses an industrial-frequency isolation transformer for high-power conversion and electrical isolation.
• Fast Transfer: Provides a transfer time of less than 10 ms between available power sources.
• Inverter Efficiency: The supplier specifies inverter efficiency above 85%.

3. 96 V Battery System

• 96 V DC Battery Platform: Designed for a compatible 96 V battery bank.
• Lead-Acid and Lithium Battery Support: Can be configured for compatible lead-acid or lithium batteries when the charging settings are correctly matched.
• 84 V Over-Discharge Protection: Helps protect the connected battery bank against excessive discharge.
• Battery Management: Supports constant-voltage charging and configurable charging settings for the selected battery system.
• Battery-System Selection: Battery chemistry, capacity, charge voltage, current limits and any required communication functions must be confirmed before installation.

4. Utility Input and Charging

• Single-Phase AC Input: Accepts compatible 220/230 V AC input with ±15% voltage tolerance.
• 50/60 Hz Input: Supports AC input frequency of 50 or 60 Hz with ±5% tolerance.
• Adjustable Utility Charging: The technical table specifies selectable utility-charging current from 0 to 70 A maximum.
• Generator Compatibility: Can be connected to a compatible generator for off-grid sites or locations with an unstable utility supply.
• Selectable Operating Modes: Supports different operating priorities for compatible utility, battery and solar configurations.

5. MPPT Solar Charging

• Single MPPT Input: Provides one photovoltaic input channel for the 96 V configuration.
• 120-300 V DC PV Input Range: Supports a compatible high-voltage photovoltaic array within the specified voltage range.
• 210 V DC Recommended PV Voltage: Provides a reference operating voltage for PV array configuration.
• 300 V DC Maximum PV Input: The array open-circuit voltage must remain below this limit under all operating and temperature conditions.
• 120 V DC Controller Overvoltage Threshold: Provides the stated overvoltage-protection value for the 96 V configuration.
• High MPPT Efficiency: The supplier specifies MPPT tracking efficiency above 99.5%.
• Configuration-Based Charging Current: The catalog lists 100 A and 200 A maximum solar-charging configurations; the standard current for the selected unit must be confirmed before ordering.

6. Protection and Monitoring

• Output Short-Circuit Protection: Responds to an output short-circuit condition.
• Overvoltage and Undervoltage Protection: Protects the system against abnormal output-voltage conditions.
• Low-Battery Protection: Helps prevent operation below the configured battery-voltage limit.
• Overload Management: Provides alarm, bypass transfer or shutdown according to the overload level and bypass configuration.
• Automatic Self-Test: Checks selected system conditions during startup.
• System Display: Provides access to operating status and system parameters.
• RS232/RS485 Communication: Supports compatible remote monitoring and power-system management.
• Automatic Recovery: Supports recovery from selected fault conditions after the cause has been cleared.

7. B2B System Applications

The inverter charger is suitable for off-grid system integrators, solar-equipment distributors, backup-power contractors and energy-system suppliers. Typical applications include homes, schools, public-lighting systems, farms, islands, remote facilities and industrial sites requiring a high-capacity single-phase AC supply.

PV array design, battery configuration, AC input conditions, load characteristics, cable size, protective devices and destination-market requirements must be confirmed before installation.
