The grid-connected inverter is a special inverter. In addition to converting DC power into AC power, the output AC power can be synchronized with the frequency and phase of the mains power, so the output AC power can be returned to the mains. Grid-connected inverters are commonly used in applications where some DC voltage source (such as a solar panel or a small wind turbine) is connected to the grid.

Advantages of Grid-Tie Inverters

High efficiency. Before the grid-connected inverter generates electricity, it needs to take power from the grid, detect the voltage, frequency, phase sequence, etc. Will be connected to the grid for power generation.

High reliability: When an accident or disturbance in the power system causes a voltage sag at the grid-connected point of the photovoltaic power station, within a certain range of voltage drop and within a certain time interval, the photovoltaic power station can guarantee continuous operation without going off-grid.

The adaptable range of input voltage is wide, not only can be used in rooftop power generation scheme, but also can be used in various small power stations.

How Do Grid-Tie Inverters Work?

When the public grid is powered off, the grid side is equivalent to a short-circuit state. At this time, the grid-connected inverter will be automatically protected due to overload. If the solar battery array has energy output, the inverter will run in the state of independent operation.

Of course, the premise of running alone is that the solar array can provide enough power at that time. If the load is too large or the sunshine conditions are poor, the inverter cannot output enough power, and the terminal voltage of the solar cell array will drop, thereby reducing the output AC voltage and entering the low-voltage protection state. When the power grid is restored, it will automatically switch to the regenerative state.

The energy storage inverter is a converter that. converts DC power (battery, storage battery) into constant frequency and constant voltage or frequency modulation and voltage modulation AC (generally 220V, 50Hz sine wave). The energy storage inverter is mainly used in the energy storage link of the grid connection, which can realize the bidirectional conversion and flow of electric energy according to the needs, and is an important part of the energy storage solution in various scenarios. Energy storage inverters mainly include centralized inverters, string inverters, distributed inverters, and micro-inverters.

Advantages of Battery Inverters

Breaking through the limitations of weather changes can reduce the impact of weather conditions on the stability of power generation and improve the stability and quality of the power grid.

It has higher power consumption efficiency, can provide users with more stable and lasting power, and avoid inconvenience and trouble caused by power system failure.

It has high stability, can realize the two-way conversion of DC and AC, and can provide a strong guarantee for power consumption when the power is cut off.

Battery Inverter Technologies and Their Applications

Higher self-use ratio.

When the power grid fails or the grid is unstable, it can automatically switch to the battery-powered mode, and the load can continue to be used.

The effect of two-way energy storage - photovoltaics can charge the battery, and the same power grid can also charge the battery; in this way, the battery can be used to adjust the peak-valley electricity price difference or be used as a backup power source.

It can also be used under pure off-grid conditions to drive loads with a certain power.

It is an upgrade based on the solar inverter, it contains the function of a solar inverter to convert DC to AC, and also adds a built-in solar controller, such as MPPT or PWM type.

Three-phase off-grid inverters convert DC power into three-phase power. A three-phase power supply provides three alternating currents with evenly separated phase angles. All three waves generated at the output have the same amplitude and frequency, but vary slightly due to loading, while each wave is 120 degrees out of phase with respect to each other.

Basically, a single 3-phase off grid is 3 single-phase inverters where each inverter is phased 120 degrees apart and each single-phase inverter is connected to one of the three load terminals.

A Three-Phase Off-Grid Inverter Advantages

The voltage of three-phase electricity is higher, which can drive high-power electrical appliances, and is mostly used in industry.

Three-phase power can provide a better voltage level and is relatively safe.

The instantaneous power of the three-phase motor is a straight line, which is equivalent to the average power and is relatively stable.

The efficiency of three-phase power transmission is much higher. At the same cost, the power transmission capacity of three-phase power is stronger than that of single-phase power.

Design Considerations for Installing an Off-Grid 3-Phase Solar Inverter

The selected battery voltage must be consistent with the DC input voltage of the inverter.

The output power of the off grid 3 phase inverter must be greater than the power used by the electrical appliances, especially for electrical appliances with high power at startup, a larger margin should be left.

The positive and negative poles must be connected correctly. The diameter of the connecting wire must be thick enough, and the length of the connecting wire should be reduced as much as possible.

It should be placed in a ventilated and dry place, beware of rain, away from flammable and explosive materials, and do not place or cover other items on the machine.

Charging and power solar inverter cannot be carried out at the same time. That is, the charging plug cannot be inserted into the electrical circuit of the inverter output during inversion.

Before connecting the input and output of the machine, please ground the shell of the machine correctly.

This is muliti-function inverter/charger, combining functions of inverter, solar charger and battery charger to offer uninterruptibel power support with portable size.
