Information

As we all know, reliable and stable power is the source of power for all equipment. However, there are still a large number of areas without mains access and poor quality of mains in the world. In these areas, off grid power solution will be in the form of grid-connected power generation. It is a useful supplement, but currently faces the following challenges:

It can easily use new energy sources, such as solar energy, wind energy, etc.; it can also allow the connection of gasoline/diesel generator sets; at the same time, it can also allow the expansion of the mains to be connected in the future. And realize the orderly linkage operation of the above several energy sources.

There must be access to energy storage systems to complement solar power generation, store energy when abundant, and achieve energy peak shaving.

With the function of smart microgrid, it can realize the intelligent management of multiple energy sources.

Limited by the installation space and the place of use, the power generation system can be installed in a distributed manner. A power generation system can be composed of several sub-power generation systems, which are logically unified and managed.

off grid power solution

Off grid power solution The direct current output by the photovoltaic array is inverted into alternating current by the photovoltaic inverter. The fan also outputs alternating current after passing through the wind energy generator set. The two alternating currents and the alternating current output by the diesel engine and the mains are fed into the AC bus. . The two ends of the two-way inverter are connected to the battery and the AC bus respectively. When the solar energy is sufficient and the load consumption is exceeded, the excess energy will be stored in the energy storage system through the two-way inverter. When the AC power is insufficient for the load, the energy storage system will The stored energy is released for use by the load.

If the distribution radius of the off grid power solution load is relatively large, in order to reduce the transmission loss, the AC power needs to be boosted by a step-up transformer before transmission; on the contrary, if the distribution radius is small, the AC power does not need to be boosted and can be directly transmitted. Transmission is for load use.
