Inverter & Controller All-in-one
Product Overview:
The LNK series integrated inverter & controller combines a solar charge controller and inverter. It converts DC power from solar panels into AC power and manages battery charging and discharging. Built-in MPPT technology optimizes solar working conditions to maximize solar energy utilization. The inverter adopts SPWM/SVPWM and IGBT modules to convert high-voltage DC into standard sine-wave AC power that meets grid standards for all types of loads.
Compared with separated inverters and controllers, this integrated design reduces volume, weight and on-site installation work. The intelligent control system monitors battery voltage, current and automatically adjusts charge/discharge strategies for optimal battery management. It provides comprehensive protections including overvoltage, undervoltage, overload, short-circuit and overheat protection, cutting off the circuit quickly under faults to protect equipment and personnel. It serves as the core equipment for off-grid photovoltaic power generation systems.
Typical Applications :
Off-grid photovoltaic power generation systems, self-consumption power supply, emergency power supply, industrial energy-saving power supply, power supply for remote mountainous areas, power supply for no-grid regions, standby power supply and independent microgrid sites.
