As a thermal energy storage (TES) solution, PCMs have demonstrated substantial potential in reducing heating and cooling demands in buildings, leveraging their ability to absorb, store, and release thermal energy during phase transitions (Saffari et al., 2022). [pdf]
Yeah, a faint humming or buzzing sound from the inverter is pretty normal especially when it's under load during peak solar generation. Inductor Noise – Inverters use high-frequency switching to convert DC to AC, and the coils inside can vibrate slightly, causing a hum. [pdf]

This standard requires that the insulation resistance of the PV system shall not be less than Riso = (Vmax_PV / 30 mA). For example, an inverter with a maximum DC input voltage of 1000V should not connect to the mains if the Riso is less than 33.3kΩ (= 1000V / 30mA). [pdf]
