Embodiment Construction
[0046] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.
[0047] Such as figure 1 As shown, the present invention provides a preferred embodiment of a control method of a solar control unit.
[0048] Wherein, at least two solar control units can communicate with each other to form a MESH network, and the control method of the solar control unit includes steps:
[0049] S10. The solar control unit acquires an instruction to replace the host from the MESH network;
[0050] S20, judging whether the solar control unit itself can be replaced as a host;
[0051] S30. If yes, set the solar control unit as a new host.
[0052] In the solar parallel system, the solar control unit can be set as a slave, and communicate with the host to form a MESH network. In the control method of the solar control unit in this embodiment, when the host computer is abnormal, the solar control unit can automatically rep...

The invention relates to the field of solar control, in particular to a solar control unit and a control method thereof, a solar parallel system and a control method thereof. The control method of the solar parallel system includes the steps: both the solar control unit and the parallel unit obtain an instruction to replace the host from the MESH network; determine whether the solar control unit can be replaced as a host; if so, set a The replaceable solar control unit is set as a new master, and the parallel unit is set as a slave. Wherein, each solar control unit and parallel unit can communicate with each other to form a MESH network. In the solar parallel system of the present invention, when the main machine is abnormal, the solar control unit as the slave can be automatically replaced with a new main machine, and the original abnormal main machine is replaced with a slave machine, and the new main machine controls the work of the entire system to ensure The normal operation of the overall system, stable system performance, and no complicated wiring, easy maintenance.
Description
technical field [0001] The invention relates to the field of solar control, in particular to a solar control unit and a control method thereof, a solar parallel system and a control method thereof. Background technique [0002] Solar energy is a kind of renewable energy, and solar power generation has been widely used in industries such as industry and agriculture. In the application of solar energy, multiple solar controllers are used in parallel to form a solar parallel system. [0003] In the existing solar parallel system, it is composed of multiple solar control units in parallel, one of which is the master to manage and control the system in a unified manner, and the other solar control units are slaves. The parallel mode is based on RS485, RS232 and other wired connections; multiple solar control units need to be connected in pairs with communication cables. The wiring is complex and troublesome, and it is prone to errors and inconvenient for maintenance. [0004] I...
