Description

The Solarix KingStar 4KVA Off-Grid Pure Sine Wave Inverter is designed to combine solar energy management, battery charging, and AC power conversion in one unit. With a rated power of 4000VA and a stated maximum watt output of 4000W, it provides a central component for compatible off-grid and backup power installations.

The inverter operates with a 24V DC battery system and delivers 230V AC output at 50/60Hz. Its pure sine wave output is designed for compatible electrical equipment that requires a stable AC power supply. Supported battery types include lithium, gel, and lead-acid batteries, subject to the battery manufacturer's requirements and the inverter's configuration.

An integrated 60A PWM solar charge controller manages charging from a compatible solar panel array. The solar charging specifications list a maximum solar charging power of 1600W, a minimum solar voltage of 30V DC, and a maximum solar voltage of 105V DC. Correct solar panel configuration is essential to remain within the inverter's permitted voltage and power limits.

The built-in AC charger provides an additional charging option when compatible mains electricity or generator power is available. The LCD display and control buttons allow users to configure charging current, select AC or solar charging priority, and adjust the acceptable input voltage range for different applications.

For additional operational flexibility, the KingStar includes automatic restart when AC input power returns and a cold start function. Overload, over-temperature, and short-circuit protection help protect the inverter during specified fault conditions. Its IP21 protection rating means that the unit should be installed in a suitable, protected indoor environment.

This inverter is suitable for users planning a properly designed solar or battery backup installation. Before purchasing, confirm the total continuous load, appliance starting requirements, battery capacity, solar panel configuration, and installation requirements with a qualified solar installer.
