1KW Pure Sine Wave Power Inverter

FI-1KW Low-Frequency Pure Sine Wave Inverter
Manufactured by Foshan Top One Power Technology Co., Ltd.
The FI-1KW is a compact, pure sine wave, off-grid inverter from Foshan Top One Power Technology Co., Ltd., a company based in Foshan, Guangdong, which has been manufacturing power conversion equipment since 2003. It belongs to the company's FI Series and is designed for small off-grid solar setups, as well as providing backup power for homes, cabins, caravans and other remote applications where grid power isn't always available.

The FI-1KW stands out thanks to its low-frequency design with a toroidal transformer. It delivers 1 kW of continuous power and can handle up to 3 kW in short surges - three times its rated output. This extra surge capacity is important because it enables you to start refrigerators, freezers, pumps and other inductive loads that draw significantly more current when they are activated. The pure sine wave output has low harmonic distortion, so there will be no interference or performance issues with sensitive electronics such as televisions, laptops, and small appliances.

The FI-1KW runs on a 12 V DC battery system, making it easy to set up with standard battery banks. Another distinguishing feature is the built-in AC charger with a maximum charging current of 35 A. This enables you to quickly recharge the batteries from the grid or a generator when solar production is low or demand is high. The charger uses intelligent charge control to optimise performance and protect battery life. There is also an automatic transfer switch that seamlessly moves between AC and battery power, ensuring that connected equipment continues to run without interruption. Protection is provided against over-voltage, under-voltage, overload and short circuits, safeguarding both the inverter and any connected devices.

The compact unit is easy to install and has a straightforward interface that doesn't require a steep learning curve. It's a practical, fuss-free choice for anyone who needs reliable off-grid power.
