FelicityESS FEL-IVEM8048 1-Phase LV Hybrid Inverter

FelicityESS FEL‑IVEM8048 is a single-phase off-grid hybrid inverter with a rated power of 8 kW designed to work with 48 V batteries and an integrated MPPT for two strings of PV panels. The device provides a pure sine wave output, grid, generator, PV, and battery power modes, as well as features such as cold start, charging priorities, and the ability to operate in parallel with up to 6 units.

The manufacturer is FelicityESS — a company providing energy storage solutions and hybrid inverters. In the product documentation, the company describes the electrical and mechanical parameters of the IVEM8048 II model and monitoring functions (built-in Wi-Fi for app operation), communication with BMS (RS485/CAN), and readiness to work with generators.
