The existing communication technologies, protocols and current practice for solar PV integration are also introduced in the report. The survey results show that deployment of communication and control systems for distributed PV systems is increasing.
Larger systems and systems where there is variation in sunlight due to seasonal changes or shading often use MPPT (maximum power point tracking) charge controllers, which are more complex but also are more effective at harvesting solar electricity.
The solar charge controller keeps working—by preventing any “reverse current” flowing from the batteries to the PV modules, and (if equipped with load control) disconnect power to the loads if the battery voltage dips too far, which can quickly kill batteries.
