15kW sine pure wave power inverter is a 3 phase off grid inverter with no battery for solar system, converts the DC power to AC power, it is useful for areas without electricity, vehicles, ships, solar energy and other renewable energy systems etc.
The load power is greater than the inverter or battery power.
A: Inverter overload: If the inverter overload exceeds the time scope, the load power exceeds the maximum value, please adjust the load.
B: Battery overload: The discharge current is generally 0.2C-0.3C, and the maximum value does not exceed 0.5C. As to one 12V200AH lead-acid battery, the output maximum power does not exceed 2400W. As to the batteries of different manufacturers and different models, the specific values are also different.
C: The load is a load such as an elevator that cannot be directly connected to the output terminal of the inverter. Because when the elevator is descending, the motor reverses, and a back electromotive force is generated. In entering the inverter, the inverter is damaged. If an off-grid system must be used, it is recommended to add a frequency converter between the inverter and the elevator motor.
D: The inductive load start-up power is too high.
The rated power of the load must be lower than the power of the inverter power, and the peak power of the load cannot be greater than 1.5 times the rated power of the inverter.
