Product Specifications

Product Details

The Crown Solar Energy Nexus 12kW Three-Phase Hybrid Inverter (CSE-N12K3P) is designed for high-capacity solar energy systems requiring reliable three-phase power management. With 12kW rated output, support for on-grid and off-grid operation, and scalable parallel capability, it is suitable for demanding residential, commercial, and industrial installations.

The inverter supports up to 24,000W of PV input power, with a 200–800V MPPT operating range, 150V starting voltage, and 1000V maximum DC input voltage. Its two MPPTs support high-power solar panels above 600W, while the system's 2× PV oversizing capability is designed to maximize energy yield.

The Crown Nexus 12kW supports 48V lithium or lead-acid batteries with a maximum charge/discharge current of 250A. Its HF isolation topology on the battery side provides enhanced electrical safety by isolating the battery from high-voltage or fault currents.

For scalable power requirements, up to six units can be connected in parallel for on-grid and off-grid operation. Six programmable battery charging and discharging periods provide greater flexibility for scheduled energy management.

The inverter is built for outdoor use with an IP66 protection rating and intelligent forced-air cooling. It operates from -25°C to 60°C, with frequency derating above 45°C. Protection functions include PV insulation resistance detection, PV reverse-polarity protection, residual-current detection, output over-current protection, output short-circuit protection, and output over-voltage protection.
