What Is Hybrid Mode in a Solar Hybrid Inverter?

Solar hybrid inverter is a key component of solar system. Xindun solar hybrid inverter has three working modes: off grid mode, on grid mode and hybrid mode. So, what is hybrid mode? Hybrid mode means that the inverter can process electricity from solar panels, battery energy storage system and mains at the same time to achieve efficient utilization and management of energy. It is generally divided into: battery priority output level, mains priority output level, solar output priority. In this article, Xindun will introduce the hybrid mode of solar hybrid inverter in depth.

What is solar hybrid inverter?

Solar hybrid inverter is a device that converts direct current (DC) into alternating current (AC) for load electrical appliances. It mainly connects "solar + battery + mains" to achieve efficient integration and flexible use of multiple energy sources. Solar and mains can power loads and charge batteries together; solar and mains  can power loads and charge batteries separately; batteries can power AC loads through inverter output. Xindun's solar hybrid inverter combines on grid and off grid functions to facilitate battery charging and discharging. During the day, when solar radiation is sufficient, the inverter prioritizes the use of solar energy to meet immediate energy needs. Any remaining energy beyond immediate needs is used to charge the connected battery. Conversely, when solar production decreases or stops, such as at night or on cloudy days, the solar hybrid inverter automatically switches to obtaining power from the battery to ensure a continuous and uninterrupted power supply. So, how does solar hybrid inverter work? We can clearly understand the working process of the solar hybrid inverter through the inverter wiring diagram below.

How does the hybrid mode work?

There are three working modes for solar hybrid inverters: on grid mode, off grid mode, and hybrid mode. Among them, hybrid mode is the most recommended and most commonly used working mode. The three common priority output upgrade methods of the hybrid mode in the hybrid inverter are: battery priority output level, mains priority output level, and solar output priority. The inverter realizes automatic switching and priority setting between different power sources according to the actual power demand, meets different power application requirements, and ensures the stability and efficiency of power supply. How do these three priority output level methods work? In what scenarios are they suitable for application?

1. Battery priority output level

If the battery priority output level is selected:

Scene 1: There is solar energy and mains

When there is solar energy and mains.

Solar energy is used to supply power to AC loads first, and after the AC load is used, the excess power is used to charge the battery.

When solar energy is insufficient, the battery will discharge to supplement, and the battery and solar energy will supply power together.

If the battery power is consumed to the set value of switching to mains, such as a 48V battery voltage (the settable range is 28-58V), if the voltage value is set to 40V, when the battery voltage is consumed to the set value of 40V, the inverter will automatically switch back to mains power supply, and solar energy will charge the battery. If the solar charging current is insufficient, the mains will complement, and the mains and solar energy will charge the battery together.

Scenario 2: Solar power but no mains

When there is solar power but no mains supply.

Solar power is used first, and after the AC load is satisfied, the excess power is used to charge the battery.

If the solar power is insufficient, the battery will be discharged to supplement, and the battery and solar power will be used to supply power together.

If the battery power is exhausted, the inverter will stop working and can only work again after the solar power is charged to a certain amount of power.

Scenario 3: When there is mains power but no solar energy

When there is mains power but no solar energy.

The inverter will give priority to battery power supply, and the AC load will be powered entirely by the battery.

If the battery power is consumed to the set value of the switchable mains power, such as the battery voltage of 48 volts (the adjustable range of 28-58V), if it is set to 40 volts, when the battery voltage is consumed to the set value of 40 volts, the inverter will automatically switch back to mains power supply and charge the battery at the same time.

When the battery power is charged to the set value of the switchable inverter, such as the battery voltage of 48 volts (the adjustable range of 36-62V), if it is set to 52 volts, when the battery voltage is charged to the set value of 52 volts, the inverter will automatically switch back to battery power supply.

The hybrid mode battery priority output stage is suitable for users in remote areas where they use electricity independently, have frequent power outages, or are not covered by the power grid and need high-quality power supply.

2. Solar priority output level

If the solar priority output level is selected.

Scenario 1: There is solar energy and mains electricity

In the case of solar energy and mains electricity, solar energy is given priority to power supply, and the AC load is powered entirely by solar energy, and any excess power is used to charge the battery.

If there is insufficient solar energy, mains electricity and solar energy are used to supply power together, such as on cloudy days.

Scenario 2: Solar power but no mains

When there is solar power but no mains supply.

Solar power is used first, and after the AC load is satisfied, the excess power is used to charge the battery.

If the solar power is insufficient, the battery will be discharged to supplement, and the battery and solar power will supply power together.

If the battery power is exhausted, the inverter will stop working and can only work again after the solar power is charged to a certain amount.

Scenario 3: There is mains power but no solar energy

When there is mains power but no solar energy.

The mains power normally supplies power to the AC load and charges the battery at the same time. If the mains power fails, the battery supplies power to the AC load. When the battery is exhausted, the inverter stops working.

The hybrid mode solar priority output stage of the solar hybrid inverter is very suitable for use in scenarios with sufficient light resources, high electricity costs and unstable mains power. Prioritizing the use of solar energy can significantly reduce the use of mains power, save electricity costs for users, and can flexibly respond to power outages. Solar power is used for power supply and storage during the day, and battery power can be seamlessly switched during power outages.

3. Mains priority output level

If the mains priority output level is selected:

Scenario 1: There is mains and solar energy

When there is mains and solar energy.

The mains power supply is given priority, and the AC load is powered by the mains power, while the solar energy charges the battery and works together.

If the solar energy is insufficient (such as cloudy days), the mains power will supplement and charge the battery together with the solar energy.

If the battery is full, the solar energy will directly power the AC load, and the mains power will not be needed to power the AC load.

If the solar energy is not enough, the mains power will complement, and the mains power and solar energy will supply power together.

Scenario 2: Solar power but no mains

When there is solar power but no mains supply.

Solar power is used first, and after the AC load is satisfied, the excess power is used to charge the battery.

If the solar power is insufficient, the battery will be discharged to supplement, and the battery and solar power will supply power together.

If the battery power is exhausted, the inverter will stop working and can only work again after the solar power is charged to a certain amount.

Scenario 3: There is mains power but no solar energy

When there is mains power but no solar energy.

The mains power normally supplies power to the AC load and charges the battery at the same time. If the mains power is also cut off, the battery will supply power to the AC load. When the battery power is exhausted, the inverter will stop working.

The mains power priority output level of the hybrid mode is "mains power as the main, solar power as the auxiliary", which is suitable for applications when the sunlight is insufficient but the mains power is stable. When the mains power fee is lower than the solar power, the mains power is used first, and the solar power is stored for backup. When the power outage occurs, it can be seamlessly switched back to the battery power supply.

HFP-S series is a dual AC output hybrid solar inverter with equal voltage, phase and frequency of the two outputs. It is mainly divided into main output and second output. The main AC output can power high-power equipment such as air conditioners and refrigerators, and the second AC output can power some small appliances, such as lights and fans. Users can set the dual output switch according to actual needs. When the dual output function is turned off, the main output and the second output can be loaded normally, and the total load power does not exceed the rated power of the inverter.

When the intelligent dual output function is turned on:

1. When the battery voltage is normal, the main output and the second output can be loaded normally, and the total load power does not exceed the rated power of the inverter.

2. When the battery voltage reaches the main cut-off voltage setting value, the main output is turned off. At this time, the maximum load power of the second output is 30% of the rated power of the inverter.

3. When the battery voltage reaches the main recovery voltage setting value, the main output is restored.

4. If the AC power is connected after the main output is cut off (that is, when working in the AC power state), the main output will be directly restored.

Xindun HFP-C solar hybrid inverter combines the dual AC output function of HFP-S. The appearance design is simple and elegant.
