2KW DSP Pure Sine Wave Inverter

FI-2KW Low-Frequency Pure Sine Wave Inverter – Manufactured by Foshan Top One Power Technology Co., Ltd.

The FI-2KW is a low-frequency pure sine wave inverter from Foshan Top One Power Technology Co., Ltd., a power electronics manufacturer based in Foshan, Guangdong, that has been operating since 2003. It is part of the FI Series, which ranges from 1KW to 6KW. It is designed for off-grid solar systems, backup power and remote installations where clean, reliable AC power is required.

What sets the FI-2KW apart is its ability to handle real-world loads. The toroidal transformer inside gives it a 6 kW surge capacity - three times its 2 kW continuous rating. This is not just a number on a spec sheet: it means that you can start refrigerators, freezers, pumps and compressors without the inverter tripping. These types of appliance draw 3 to 7 times their running current when they start up, and the FI-2KW can handle that easily. The output is a pure sine wave with low distortion, so it won't cause problems with sensitive equipment such as medical devices, audio equipment or computers.

The FI-2KW runs on 12V, 24V or 48V battery banks - you can choose the voltage that suits your system. It automatically detects and adapts to different battery chemistries, including gel, sealed lead-acid, AGM and lithium. It has a 35 A adjustable AC charger that uses a three-stage profile to keep batteries healthy. The transfer switch moves between battery and AC input in under 4 ms, ensuring that connected equipment continues to run when the grid fails. Three operating modes - AC priority, battery priority and ECO mode - let you decide how the unit manages power.

The display shows the voltage, current and system status in real time, and optional Bluetooth or Wi-Fi is available for remote monitoring. Protection is provided against over-voltage, under-voltage, overload, short circuit and over-temperature, with automatic shutdown when specifications are exceeded. Backed by the manufacturing and quality control of Foshan Top One Power Technology Co., Ltd., the FI-2KW is a solid, reliable choice for off-grid power.
