Microchip has developed the Residential Photo voltaic Breaker Reference Design that includes the HV9901, for instance reference breaker resolution for single-phase residential photo voltaic installations. All of the Reference Design parts, together with the HV9901, are rated to 125°C, a vital function for these programs as they’re required to function within the high-temperature setting of the photo voltaic panel. This increased ranking helps to make sure lengthy working life of those programs on this harsh setting.
The power monitoring is supported by MCP39F511A. Energy monitoring in photo voltaic installations offers a number of advantages to the client like fault monitoring to detect a defective inverter or panel which might trigger hazardous conditions and alerts in case of drop-in efficiency. Provision for extra security and robustness comes from the flexibility to put in the MCP9701, which can be utilized to regulate the efficiency on account of over-temperature circumstances (like disconnecting the inverter from the load in case of extreme temperature.)
The Residential Photo voltaic Breaker Reference Design combines two functionalities: a relay driver utilizing the HV9901 and an influence monitor utilizing the MCP39F511A. It makes use of the HV9901 to drive a relay which permits the consumer to attach/disconnect the photo voltaic inverter from the grid connection. The MCP39F511A permits the consumer to observe the real-time energy (each energetic and reactive) from the photo voltaic inverter. The ability monitoring stage makes use of the Energy Monitor Utility software program for measurement by way of a USB connection to the board. The Energy Monitor Utility software program is used to calibrate and monitor the system. The software program gives an computerized step-by-step calibration course of that can be utilized to rapidly calibrate energy meters.
