The FSI-302 is a premium hybrid solar inverter engineered to meet the demanding power needs of larger residential homes, workshops, and small commercial setups. At its core, it delivers a steady rated power of 3KW alongside an impressive 9KW surge capacity, ensuring it can effortlessly handle heavy-duty appliances and inductive or capacitive loads through its clean, pure sine wave output.

Designed for maximum versatility and efficiency, the FSI-302 supports both 24V and 48V battery systems and is compatible with a wide range of battery chemistries, including Gel, SLA, AGM, and Lithium. It features an advanced integrated charging system that combines an adjustable AC charger (up to 35A) with an optional MPPT solar controller, guaranteeing fast, intelligent, and safe battery charging.

Reliability is at the forefront of its design. The unit boasts an ultra-fast transfer time of 4ms or less, allowing it to function seamlessly as a UPS for critical equipment like computers and servers. It is built around a durable toroidal transformer that ensures long-term operational stability and high efficiency of over 85%. Furthermore, the FSI-302 provides users with comprehensive control through four selectable working modes (including AC mains priority and Unattended mode) and a multi-layer protection system that actively guards against overloads, over-temperature, and short circuits.

Beyond its robust hardware, the FSI-302 is designed for user-friendly operation and long-term peace of mind.

It typically features an intuitive LCD display or interface that allows users to easily monitor system status, battery levels, and real-time power generation at a glance. Backed by comprehensive technical support and a solid warranty, this inverter not only maximizes your solar investment but also provides a seamless, worry-free energy experience for years to come.
