FTS series hybrid solar inverter with mppt controller 12v

To ensure that the harmonic content of the inverter output voltage within the rated load range meets the requirements of the national standard, the harmonic requirements are mainly met by adopting high-performance power devices, improving the control algorithm, and compensating for the dead zone of the power device. Protection and control requirements: The output voltage cannot be changed to zero when overloaded, and can only be appropriately limited; the output voltage can be cut off in time when the output is short-circuited, and can withstand long-term short-circuit faults; when the output is connected to an inductive load, the output voltage should not be affected. cause excessive influence; when the overload or short-circuit fault is removed, the equipment should be able to automatically resume work.

The off-grid inverter provides power for the load, and its output voltage needs to strictly meet the load demand. Therefore, the control of the inverter output voltage is the primary function of the off-grid controller, which mainly includes voltage RMS and frequency control. The output voltage can be guaranteed to be stable at the rated value through the real-time control of the modulation ratio of the SPWN wave, and the output frequency can be guaranteed to be stable at the rated value by controlling the carrier wave ratio.
