New government policy combined with new regulation is driving renewable energy generation, and the solar market is expected to have strong growth in the future. Due to the current increase of power density in solar inverters and the demand for energy storage balancing, this generation of solar power leads to a need to significantly monitor all elements of a solar system.

RS-485 is the communication application of choice for PC screen data updates such as current power, current consumption in the maximum power point trackers, battery charge and health, and CO2 reduction, etc., are available, as can be seen in figure 2.

Figure 3 illustrates a typical solar system with input-for-input dc strings, dc-to-ac conversion, energy charging and storage, and battery management and communications.
