Product Overview
The GoodWe ET LV 15kW 3-phase hybrid inverter is a high-capacity low-voltage storage inverter designed for larger residential solar systems that need strong three-phase output and flexible battery integration. Built around a 48V battery platform, it offers higher PV input capacity, four MPPTs and backup-ready functionality for homes with heavier and more complex energy demands.
Key Features
- 15kW three-phase hybrid inverter designed for advanced residential energy storage systems.
- Compatible with 48V LiFePO4 and lead-acid battery systems.
- Up to 30kW PV input capacity supports larger solar array designs.
- 4 MPPTs with 20A max input current per MPPT help improve flexibility across multiple roof sections and orientations.
- Dual independent battery inputs support higher energy throughput and flexible battery configuration.
- Seamless switching under 4ms helps maintain backup supply to essential loads during outages.
- Supports generator integration and battery charging from the generator side.
- Unbalanced output up to 150% helps support real-world three-phase load conditions.
Applications
- Larger homes with high daily energy use and three-phase supply.
- Residential systems combining substantial solar generation with low-voltage battery storage.
- Backup-focused installations where continuity during grid interruptions is a priority.
- Projects needing broader PV design flexibility across multiple roof faces.
Why Choose This Product?
The ET LV 15kW is well suited to households that need more solar input capacity, more MPPT flexibility and stronger battery integration within a low-voltage platform. It gives installers and system designers more room to build robust three-phase storage systems while keeping backup performance and future expansion in mind.
