Power your home independently from the grid with Rocksolar's collection of off-grid and hybrid solar inverters, sized from 3kW for smaller setups up to 12kW for larger residential loads. These inverters run entirely on solar and battery power, making them a fit for homes without utility grid access or anyone building a self-sufficient backup power system.

Most models support both single-phase and split-phase 120/240V configurations, with integrated MPPT solar charge controllers, LCD displays, and pure sine wave output for clean, reliable power to sensitive electronics. Several units also offer Wi-Fi and app monitoring, letting you track battery status and system performance from your phone, and are compatible with both LiFePO4 and lead-acid battery banks.

Whether you're running a compact 3.5kW system for essential loads or a 12kW inverter to cover a full household, these off-grid inverters give you the flexibility to build a self-contained power system without ties to the utility company.
