FSC-8-12K1P-BL Off-Grid Inverter – 12 kW

FSC-8-12K1P-BL is an advanced off-grid solar energy storage inverter that combines solar charging, grid charging, and pure sine wave AC output into a single system. Powered by a digital signal processor (DSP), it delivers fast response, high efficiency, and stable performance across different energy scenarios.

The inverter supports multiple working modes including PV priority, grid priority, and inverter priority, allowing flexible power management based on user needs. It also features UPS functionality with seamless switching between grid and battery power.

Designed for versatility, it supports both lithium (LiFePO4) and lead-acid batteries, with intelligent charging control and up to 250A charging capability. Dual AC outputs enable smart load distribution, while communication options like CAN, RS485, USB, and Wi-Fi allow easy monitoring and integration.

With support for parallel operation (up to 9 units), generator input, and advanced protection features, this inverter is ideal for off-grid homes, solar backup systems, and small to medium commercial setups.
