Everything about 3 Phase Hybrid Inverter

If you are considering buying a solar inverter, you must have come across a three phase solar inverters. So let us tell you exactly what a hybrid 3 phase solar inverter is in the simplest way possible.

The PV modules of your solar system produce direct current (DC), which is incompatible with household appliances. So, you need a solar inverter turns the DC energy into AC (alternating current) power.

A 3 phase hybrid inverter performs this function while simultaneously charging the solar batteries, saving the excess energy produced during the day. A much smarter device, these hybrid 3 phase inverters can execute various additional functions and have been established as an essential part of the future of solar systems.

Read on to know more about how these solar inverters operate.

What is a 3 Phase Hybrid Inverter?

A three phase inverter is a device that converts direct current (DC) power from a battery or a solar panel into alternating current (AC) power that can be used by three-phase appliances or the grid. The three phase inverters produce three AC waveforms that are 120 degrees apart from each other, creating a balanced and stable power supply. A three phase inverter is commonly used in high-power and variable-frequency applications, such as industrial motors, renewable energy systems, and electric vehicles.

How these Three-Phase Hybrid Inverters Work?

The 3 phase hybrid inverter works by using a bidirectional DC/DC converter and a bidirectional DC/AC inverter. The DC/DC converter can charge or discharge the battery depending on the power demand and supply. The DC/AC inverter can synchronize with the grid or operate in island mode depending on the grid availability and the backup power requirement

There different operation modes of the three-phase hybrid inverters, such as:

Solar priority mode: In this mode, the solar power is used to supply the load and charge the battery. If the solar power is insufficient, the battery power is used to supplement the load. If the battery is fully charged and the load is low, the excess solar power is exported to the grid

Grid priority mode: In this mode, the grid power is used to supply the load and charge the battery. If the grid power is unavailable or expensive, the solar power and the battery power are used to supply the load. If the grid power is cheap and the battery is low, the grid power is used to charge the battery

Backup mode: In this mode, the hybrid 3 phase solar inverter disconnects from the grid and operates in island mode. The solar power and the battery power are used to supply the load. If the solar power is excess, the battery power is charged. If the battery power is low, the load is reduced or switched off.

Technology Commonly Used by Hybrid Inverters Three Phases

Maximum power point tracking (MPPT): This is a technology that optimizes the power output of the solar panels by adjusting the voltage and current to match the maximum power point of the PV array. MPPT can increase the efficiency and performance of the solar system, especially in variable weather conditions.

Pulse width modulation (PWM): This is a technology that controls the switching frequency of the inverter to produce a modified sine wave AC output. PWM can reduce the harmonic distortion and noise of the inverter, as well as the heat and power loss. However, PWM inverters are less compatible with some sensitive and high-end appliances than pure sine wave inverters.Pure sine wave: This is a technology that produces a smooth and stable AC waveform that is identical to the grid’s AC waveform. Pure sine wave inverters are more efficient, reliable, and compatible with most appliances than modified sine wave inverters. However, they are also more expensive and complex than PWM inverters.

Features of 3-Phase Hybrid Solar Inverter

High efficiency: A 3-phase solar inverter can reduce the power loss and increase the power output of the solar system, as it produces three AC waveforms that are 120 degrees apart from each other, creating a balanced and stable power supply.

Reduced harmonic distortion: Three-phase solar inverter can lower the harmonic distortion and noise of the AC output, as it has a higher switching frequency and a smoother waveform than a single-phase inverter.

Better voltage regulation: A 3-phase solar inverter can maintain a constant and consistent voltage across the load, as it can compensate for any voltage fluctuations or imbalances in the grid or the load.

High power capacity: A 3-phase solar inverter can handle higher power demands and complex wiring configurations than a single-phase inverter, as it can distribute the power among three phases and reduce the current and the cable size.

Smart monitoring and programming: A 3-phase solar inverter can offer more features and benefits, such as smart monitoring, remote control, surge protection, and grid support. You can use a remote control, an LCD display, a smartphone app, or a web portal to access and adjust the parameters of your 3-phase solar inverter, such as input and output voltage, current, power, frequency, battery level, load percentage, and error codes. You can also set the priority of the power sources, such as solar, battery, or grid/generator.

Conclusion

All in all, hybrid 3 phase inverters are a superpower in the world of solar systems. They convert DC to AC like any regular solar inverter while simultaneously charging the solar batteries.  Wholesale SVC Three-Phase Hybrid Solar Inverter, maximum efficiency 99.8%
