The EG4 12kPV is a 48V split-phase hybrid solar inverter delivering 8kW of continuous output with 12kW of solar input capacity, built for residential and light commercial installers who need a dependable, cost-effective hybrid inverter with robust off-grid capability. Sharing its core architecture and firmware with the EG4 18kPV, the 12kPV provides the same proven performance at a lower power tier — ideal for smaller homes or projects where 8kW of continuous output meets the load requirement.
The 12kPV features dual high-voltage MPPT inputs (120–500 VDC, 25A each) supporting arrays up to 15kW, with a 10ms transfer time that keeps critical loads running without interruption during grid transitions. Its ability to parallel up to 10 units gives installers a path to scale up to 80kW on larger projects without changing inverter platforms.
The 12kPV is fully compatible with the EG4 WallMount 280Ah battery and other EG4 storage products, and supports closed-loop battery communication for optimized charge management. Its high-frequency design eliminates the need for heavy transformers, and the NEMA 4X/IP65 enclosure rating makes it suitable for outdoor installations in a wide range of climates. A reliable, field-proven choice for off-grid, grid-tied-with-storage, and generator-backup hybrid solar systems.
A hybrid inverter combines a solar inverter, battery charger, and automatic transfer switch in one unit. The EG4 12kPV can power your home from solar, charge connected batteries, and automatically switch to battery backup during a grid outage — all without manual intervention.
Yes. The EG4 12kPV operates in grid-tied solar-only mode without batteries installed. You get solar savings immediately and can add EG4 battery storage later. Note: without batteries, the inverter cannot provide backup power during a grid outage.
Yes. The EG4 12kPV supports full off-grid operation with a compatible battery bank. It can island from the grid and power your home entirely from solar and stored energy.
The EG4 12kPV is natively compatible with EG4 batteries and also supports many third-party LFP batteries via CAN/RS485 communication. Contact us at (346) 432-4228 to confirm compatibility with a specific battery.
The EG4 12kPV is UL 1741 listed, meeting U.S. grid interconnection requirements. Always verify local utility interconnection requirements with your installer before purchasing.
