A 3-phase high voltage hybrid inverter is a multi-functional device that combines the functions of both a solar inverter and a battery pack. This provides the ability to store excess energy in the battery for later use, especially at night and during power outages. It balances all the functions, including generation, operation, and storage.
A three-phase inverter is a device that transforms DC to unstable AC. In this era of renewable energy, the 3-phase inverter is the most efficient and sustainable solution for commercial and residential properties. This inverter can manage the power distribution among three phases.
A three-phase inverter is used in a solar system as a connection between the DC output of the PV array and your electrical grid or load, and it is used to produce high-quality AC. Since the output is balanced, the power is distributed more uniformly between phases, which prevents a lot of stress on the wiring, and the loss is minimized. This blog post will share the ins and outs of a 3-phase high-voltage inverter for a commercial solar electric system. So, let’s get into it.
Three-phase Hybrid Inverter for a Commercial Solar Electric System
Reliability and efficiency of energy are key business success factors in the contemporary fast-paced business environments. The increasing prices of electricity and the growing energy requirements have attracted a lot of solar energy in industries, offices, and a wide range of applications as a solution. The inverter is at the center of any effective solar energy system, and in commercial situations, the most effective and powerful one is the three-phase high-voltage hybrid inverter.
Key Features of a Three-Phase Solar Inverter
There are some key features that you must put at the top of your checklist while selecting the appropriate three-phase high voltage hybrid inverter. To begin with, there is the efficiency rating of the inverter. Increased efficiency ratings imply a decreased amount of energy loss in the conversion process.
The second step is to measure the compatibility of the inverter with the various kinds of batteries and solar panels. A universal inverter will enable you to expand or alter your solar system without the need to have to overhaul your whole solar system. Simple installation and monitoring are also essential. The following are some other key features of the 3-phase high voltage hybrid inverter.
- Have high efficiency: conversion rate is over 97%
- Has a three-phase grid tie system.
- They come with a battery backup.
- The voltage support is compatible with 208 VAC and 480VAC.
- It supports wifi and has app monitoring
- Often comes with a warranty of 10-15 years.
Technologies Used in the Three-Phase Hybrid Inverter
There are two technologies used in a 3-phase high-voltage hybrid inverter. These are PWM and MPPT. Both are algorithms and are utilized in the majority of contemporary solar inverters in general.
PWM Solar Inverters
These were in use in the 90s. But the PWM algorithm is scarcely utilized at the moment. PWM is a short form of Pulse Width Modulation. This algorithm minimizes the current of solar panels to the charging voltage that is safe for batteries. The final product is a waste of energy.
MPPT Solar Inverters
Unlike PWM, which diminishes the output of the panel, the MPPT algorithm identifies an optimum point at which the panels are generating the highest level of power. The sunlight conditions change during the day, so the MPPT algorithm is a real-time method to provide the panels with the maximum power that is possible at any given time. The MPPT technology can be 30 per cent more efficient than PWM.
How Does a Three-Phase Hybrid Solar Inverter Work?
The panels are converted into DC power by a three-phase commercial solar power system that employs fast electronic switches, there are many of them inside, to switch the DC power on and off very rapidly and convert it into three AC waves that are spaced 120 degrees apart.
Steps of the Three-phase Hybrid Solar Inverter Working
- 1. lépés: Sunlight on the solar panel is utilized to produce DC electricity. Your panels can receive solar signals and convert them into direct current DC electricity. DC provides a one-way flow of electrons, which is constant.
- 2. lépés: In this step, the DC power, which is present in the panel strings, is transmitted through the channels and safety switches to the inverter. The inverter then starts by checking the wiring and voltages, then proceeds to work.
- 3. lépés: The inverter implements the embedded MPPT algorithm to maximize power extraction. The MPPT algorithm in the inverter continuously changes voltage and current to ensure that solar panels are producing as much power as they can at that time.
- 4. lépés: The inverter generates AC waveforms. The solar power inverter is a three-phase model using very fast electronic switches, which chop and shape the DC into three wave forms that are offset by 120 degrees each. It is what makes it a three-stage supply.
- Step 5: The inverter synchronizes with the grid. Before supplying power to the on-grid and hybrid three-phase solar inverters measure the grid voltage and frequency and adjust themselves to match it.
- Step 6: In a three-phase property, the inverter is fed from three lines (L1, L2, L3) to share large loads rather than forcing them onto a single line. They are also equipped with some earth wire. Certain 3-phase PV inverters employ neutral wires.
- Step 8: The commercial solar system makes sure your home/business can use the solar energy first. Your appliances consume solar power as soon as possible. The hybrid system uses the additional power to charge the lithium batteries and direct it to the grid. Extra solar power is used in the off-grid solar system to charge the batteries.
The Difference Between Single-Phase and Three-Phase Solar Inverters
The primary difference between single-phase and three-phase solar inverters is the allocation of power by each.
Single-phase solar inverter
One phase inverter delivers one waveform of AC output. It is linked to a single-phase utility service and may also be applicable to a three-phase property. However, in that case it typically gets connected to only one of the phases, which may need phase balancing according to utility regulations. These inverters are typically meant to serve smaller systems (usually 1-10kW) and only provide load balancing for single-phase systems. Single-phase inverters are not very efficient with high-power systems, but they are cost-effective and suitable for small and medium residential systems.

Conversely, a three-phase high voltage hybrid solar inverter can produce about a 120-degree spaced AC waveform, which is connected to a 400/415V, 50Hz three-phase utility service. It is best suited to buildings that already have the three-phase supplies. They balance the load as well as power export among the three phases, making them more even to operate. Since the current is shared between three lines, the lines are more efficient in handling heavy or motor loads, and the stability of the system is also more secure.
Overall, single-phase solar inverters apply to smaller homes wth fewer energy requirements, whereas the three-phase solar inverters are typically used in larger houses and businesses that need larger capacity, smooth operation, and balanced power across all phases.
Phases in Commercial Solar Installation
For commercial solar installation, the foremost step is the site assessment. The engineers consider roof space, load profile, and energy consumption patterns. After that, the team will determine the system design, which includes the layout of the arrays, inverter, capacitor, and battery size based on the requirements. After that comes the phase of commercial solar installation. The panels, inverters, and battery units are fitted with appropriate wiring and protection. After that, testing of the system is done on voltage, phase balance, and system performance under load conditions. Once the system is installed, it is tied to a monitoring platform where it can monitor its performance in real time.
Benefits of the Three-Phase Hybrid Inverter
A three-phase inverter has numerous benefits and is therefore suitable for large residential, commercial, and industrial solar systems.
To begin with, it has a larger system size, which enables more power output and is more appropriate for commercial rooftops. It provides a smooth operation with motor-heavy loads as the pumps, compressors, and multiple air conditioners, due to the equal distribution of power between all phases.
It also greatly minimizes the dangers of voltage trips since there will be a sharing of power export over three lines, avoiding overloading on one line. It also has more MPPT inputs, which allow more flexibility in roof layouts. It has high-level monitoring and grid support capabilities, which enable users to monitor performance and meet utility requirements easily.
In a nutshell, the three-phase solar inverter means a commercial solar system that guarantees power balance, great efficiency, and smarter energy management in the era of rising energy demands.
