Solar Three Phase Hybrid Inverter 5kW-12kW
Model：
THS3P-5kW/ 6kW/ 7kW/ 8kW/ 10kW/ 12kW
Keqi Energy offers the EU-standard Three-Phase Hybrid Inverter series (5kW-12kW). Specifically designed for 380V/400V grids, it supports 18A high-power modules and 200% PV oversizing. Features 200% off-grid surge power for 15s. Reliable factory-direct supply with OEM/ODM support for global distributors and installers.
Key Feature
High-Current Compatibility (18A/36A): Specially optimized for mainstream high-power PV modules. Supports 18A per string and a total maximum input current of 36A, ensuring maximum energy harvest from Tier 1 solar panels.
200% PV Oversizing Capability: Allows for double the PV input capacity relative to the rated power. This ensures sufficient energy for both off-grid loads and rapid battery charging, even during low-light conditions.
Superior Off-Grid Peak Power: Features a robust 200% peak overload capacity for up to 15 seconds in off-grid mode. Easily handles high starting currents of inductive loads like air conditioners or pumps.
Industrial-Grade Stability: Designed for 380V/400V three-phase grids (50/60Hz). Offers seamless switching and advanced thermal management, making it the ideal choice for stable energy independence in EU-standard regions.
Factory-Direct OEM/ODM Services: We provide customized software, branding, and technical support directly from our production line, ensuring wholesale clients receive the best price-to-performance ratio.
