FSOLAR CHISAGE 8kW G2 Single-Phase Hybrid Solar Inverter

The FSOLAR CHISAGE 8kW G2 Single-Phase Hybrid Solar Inverter – JUP-8G2-LE is an advanced hybrid energy-management solution designed to integrate solar panels, battery storage, utility-grid power, EPS backup, and compatible diesel-generator power into one intelligent system.

The JUP G2 Series supports flexible on-grid and off-grid operation, programmable battery charging and discharging, generator-assisted charging, and expandable parallel operation. The datasheet lists the JUP-8G2-LE alongside the G1 version with the same published 8kW electrical performance specifications.

With 8,000W rated AC output, up to 9,600W maximum AC output, and 12,000W maximum PV input, it offers strong performance for larger homes, shops, offices, farms, workshops, remote sites, and professional energy-storage applications.

Powerful 8kW Single-Phase Output

The FSOLAR CHISAGE JUP-8G2-LE provides stable 230V single-phase AC power at 50Hz or 60Hz.

AC Output Performance

• Rated AC output and UPS power: 8,000W
• Maximum AC output power: 9,600W
• Output voltage: 230V AC
• Grid type: Single Phase
• Output frequency: 50Hz / 60Hz
• Rated AC output current: 34.78A
• Maximum AC current: 41.73A
• Maximum continuous AC pass-through current: 50A
• Peak off-grid power: 2 × rated power for 10 seconds
• Power factor: 0.8 leading to 0.8 lagging

The high short-duration peak capability helps support compatible equipment with higher startup requirements when the battery bank, cables, breakers, and complete system are correctly designed.

Dual MPPT with 12kW Solar PV Input

The JUP-8G2-LE supports up to 12,000W maximum DC PV input, allowing significant solar-panel capacity to be connected to the 8kW hybrid system.

Solar Input Specifications

• Maximum DC input power: 12,000W
• Maximum PV input voltage: 500V DC
• Nominal PV input voltage: 370V DC
• PV operating voltage range: 125–500V DC
• MPPT range: 125–425V DC
• Startup voltage: 120V DC
• PV input current: 26A + 26A
• Maximum PV short-circuit current: 34A + 34A
• Number of MPPT trackers: 2
• Strings per MPPT: 2 / 2
• MPPT efficiency: 99.9%

Solar-panel strings should always be designed so that the maximum open-circuit voltage remains within the inverter’s permitted PV limits under expected temperature conditions.

High-Power Battery Charging & Discharging

The FSOLAR CHISAGE JUP-8G2-LE supports lithium-ion and lead-acid batteries operating within a 40–60V DC battery range.

Battery Specifications

• Battery type: Lithium-ion / Lead-acid
• Battery voltage range: 40–60V DC
• Maximum charge current: 190A
• Maximum discharge current: 190A
• Charging curve: 3 Stages / Equalisation
• External battery temperature sensor: Optional
• Lithium charging strategy: Self-adaptation to BMS
• BMS communication: CAN / RS485

Charging and discharging limits should always be configured according to the specifications of the connected battery and BMS.

Intelligent BMS Communication

The inverter supports CAN and RS485 communication with compatible lithium battery-management systems.

The published lithium charging strategy is self-adaptation to BMS, allowing compatible inverter and battery systems to coordinate charging parameters.

Time-Based Energy Management

The JUP G2 Series supports battery charging and discharging according to programmable time settings.

This can be useful for:

• Charging batteries during selected periods
• Maximising daytime solar-energy use
• Using stored energy at night
• Reducing grid consumption during peak periods
• Reserving battery capacity for emergency backup
• Managing generator-assisted charging

On-Grid, Off-Grid & EPS Operation

The FSOLAR CHISAGE JUP-8G2-LE supports:

• On-grid operation
• Off-grid operation
• On-grid/off-grid mode switching
• EPS emergency backup output
• Solar energy storage
• Battery backup
• Grid-assisted operation
• Generator-assisted operation

This provides flexibility in how solar, battery, grid, and generator energy are managed.

Independent Diesel Generator Input

An independent AC input port for a compatible diesel generator is included, and the system supports storing generator energy in the connected battery bank.

This makes the inverter suitable for farms, workshops, remote sites, commercial facilities, and locations with unreliable utility power.

Parallel System Expansion

The JUP G2 Series supports up to 20 compatible inverters in parallel for off-grid operation and also supports compatible different-power inverter parallel connection.

This makes the system expandable as future power requirements increase.

5-Inch Colour Touchscreen

The inverter incorporates a 5-inch colour touchscreen LCD, providing convenient system monitoring and configuration together with an IP65 protection rating.

Users can monitor information such as solar production, battery condition, grid status, load demand, charging/discharging status, operating modes, settings, alarms, and warnings.
