CPU management, intelligent control, modular composition, more convenient after-sales maintenance;

LED+LCD display, can visually display all the running parameters of the machine.

When the load is connected with the power frequency inverter, the load must be closed first, then connected, and then opened one by one.

Connect the inverter to a special socket with overcurrent protection device.

Sine wave inverter can output complete sine wave because it adopts SPWM which is more advanced than PWM.

Common off-grid inverters include square wave, quasi-sine or sinusoidal inverters. Square wave inverters are widely used due to their simple circuit, low price and high inverter efficiency. They are suitable for simple resistive loads. #solar inverter hybrid For example, ordinary light bulbs, various energy-saving lamps with switching frequency conversion circuits, electric heaters, electric kettles, electric irons, computers, mobile phone chargers, etc.#ups inverter However, the waveform of the square wave inverter is seriously distorted and contains a large number of high-order harmonics. When a capacitive load or an inductive load is connected to the circuit, the high-order harmonic current output by the inverter will generate additional eddy currents on the inductive load. loss, causing serious heating of load components, seriously affecting the operating efficiency of the system, and even causing damage to electrical equipment.

Usually, a sine wave inverter should be selected for a general off-grid photovoltaic power station. #solar inverter 5kw Although the price is high, it has good versatility and can meet the normal operation of various loads. The sine wave inverter with the maximum waveform distortion (or harmonic content) not exceeding 5% (single-phase output allows 10%) should be selected.
