FSolar CHISAGE VEN 6KW G1 Single Phase Hybrid Solar Inverter-VEN-3-6.6 G1-LE

The FSOLAR VEN-6G1-LE 6KW Single Phase Hybrid Solar Inverter is designed for advanced solar power and energy-storage systems requiring reliable power management, high PV capacity, and flexible battery integration.

With a 6000W rated AC input/output power and maximum apparent power of 6600VA, the VEN-6G1-LE provides strong performance for single-phase applications. In off-grid operation, the inverter supports peak power up to 2 times its rated output for more than 10 seconds, providing additional capability for demanding startup loads.

High-Capacity Solar Input

The 6KW G1 model supports up to 9000W maximum PV input power, allowing a larger solar array to be connected to the inverter. It features a 500V maximum PV input voltage, 125V start-up voltage, and an MPPT operating range of 150–425V.

The inverter incorporates 2 MPPT trackers with 1+1 PV strings, helping optimize energy harvesting from the connected solar panels. Maximum operating PV input current is 18A + 18A, while maximum PV short-circuit current is 27A + 27A.

48V Lithium & Lead-Acid Battery Support

The FSOLAR VEN-6G1-LE operates with a 48V battery system with a supported range of 40–60V. It is compatible with both lithium-ion and lead-acid batteries and provides up to 135A battery charging and discharging current for the 6KW model.

For lithium batteries, the inverter supports self-adaptation to the battery BMS, with CAN and RS485 communication available for compatible battery systems.

Hybrid & Generator Operation

The inverter supports flexible energy management with:

• On-grid and off-grid mode switching
• EPS output
• Battery charging/discharging according to time settings
• Independent AC input for a diesel generator
• Energy storage from the generator
• Different-power inverter parallel connection
• Up to 20 inverters in parallel for off-grid operation
• Optional ARC fault detection

High Efficiency

The VEN-6G1-LE is engineered for efficient solar energy conversion with:

Maximum Efficiency: 97.60%
Euro Efficiency: 96.50%
MPPT Efficiency: 99%

Protection & Reliable Operation

The inverter integrates multiple protection functions, including PV input lightning protection, anti-islanding protection, PV reverse-polarity protection, insulation-resistance detection, residual-current monitoring, output over-current protection, and output short-circuit protection. Optional PV ARC fault detection is also supported.

With an IP65 protection rating, wall-mounted construction, smart cooling, and an operating temperature range of -45°C to 60°C with derating above 45°C, the inverter is designed for dependable operation across demanding environments.
