⌈Inverter Introduction⌋

Solar and AC hybrid inverter is applied to solar energy storage micro-grid system. Solar system could be with or without storage battery configuration. A solar energy storage micro-grid system is made up when batteries are configured. A solar energy micro-grid system is made up when batteries are not configured. The system uses PV energy as priority. When the energy of PV is not enough, it can be supplemented by city power or batteries. When the PV energy is surplue, it would be stored in batteries, to maximize the utilization of PV power generation, so as to achieve the purpose of electricity cost saving.

⌈Inverter Batteries⌋

The off grid solar and ac hybrid inverters can be flexibly equipped with batteries. The advantage and application sites of no batteries, small-capacity batteries, and standard-capacity batteries are shown in the figure below.

 

⌈Inverter How to Use⌋

Here I introduce how to use the inverter:

AC Modes

1 When the power grid is normal and the current solar power generation is bigger than the load power, solar power will feed the load completely and the surplus solar power will feed the battery and transmit to the grid.
2 When power grid is normal and the solar power is smaller than the load power, the insufficient part is supplemented by the power grid; The solar and the power grid feed the load together.
3 When power grid is abnormal, the inverter changes to independent invert mode. When the solar power is bigger than the load power, the solar power will feed the load completely, and the surplus part will charge the battery. When the solar  power is smaller than the load power, the insufficient part is supplemented by the battery; the batteries and the solar feed the load together.
4 When solar has no generating power, the power grid will charge and store energy to the battery through the inverter.
5 When power grid is abnormal and there is no solar, batteries will feed the load.

Battery Modes

1 When the power grid is normal and the current solar power generation is bigger than the load power, solar power will feed the load completely and the surplus solar power will feed the battery and transmit to the grid.
2 When the solar power is smaller than the load power, the insufficient part is supplemented by the battery. The solar and the battery will feed the load together.
3 When solar power runs out or very little and the battery is placed to below 48/96/192/240 voltage (Depends on different solar system voltage), the discharge power of the battery will be linearly reduced. The insufficient part will be supplemented by power grid. And when it reaches the low-voltage protection of the battery, the load will be completely fed by the power grid.
4 When power grid is abnormal, the inverter will work in the independent invert mode. The solar power will feed the load. And if the solar power is insufficient, it is supplemented by the battery.
Note: under the BATT mode, if there is no solar, power grid won’t charge the battery.

 

With power grid, solar, and batteries, inverter always uses solar energy first:

1, If the solar power generation is 1000W and the AC load is 600W. The solar power supply 600W to the AC load, and 400W is left to charge the battery. At this time, the power grid does not provide energy.

2, If the solar power generation is 1000W, the AC load is 1600W. The solar power supply 1000W for the AC load, the power grid supply 600W for the load (AC priority mode) or the battery supplies 600W for the load (Battery priority mode)

 

No power grid and batteries, but solar is available, the inverter automatically turns on and operates in the solar state, and the AC load is completely powered by the solar energy.

If the solar power generation is 1000W, the total power of the AC load can only be ≤1000W, and over 1000W will trigger the overload protection.

 

No solar and batteries, but power grid is available, the inverter automatically turns on and operates in the power grid state, and the AC load is completely powered by the power grid.

If the power gird is powered off, the AC load cannot continue to operate.

 

No battery, but power grid and solar is available, inverter always uses solar energy first:

1,If the solar power generation is 1000W, the AC load is 600W. The solar powers the AC load to 600W. At this time, the power grid does not provide energy.

2,If the solar power generation is 1000W, the AC load is 1600W. The solar power supply 1000W and the power grid supply 600W for the AC load.
