scope:

This part of IEC 63349 defines operation modes of photovoltaic direct-driven appliance (PVDDA) controllers and describes one example of a graphic display. The graphic display is an interface to PVDDA users, which uses easily understood graphics to show a real-time operation mode, such as what equipment is installed, controlled and monitored in the system, which equipment is generating power and how much it generates, and which equipment is consuming power and how much it consumes. This helps with user's interest, knowledge, planning on renewable energy usage.

IEC 63349 is a series of standards for PVDDA controllers which can be used in various appliances including air conditioners, water pumps, refrigerators, etc. These standards only cover the requirements of PVDDA controllers.

Requirements for appliances are covered by their specific standards, for example, standards developed by IEC TC 59 on performance of household and similar electrical appliances, or by IEC TC 61 on safety of household and similar electrical appliances.
