Martin Vazquez from Rosario, Santa Fe, Argentina operates the POW-HVM4.2M-24V-N inverter purchased in October 2024. The system has run reliably for over one year, even under extreme summer conditions of 40°C and high humidity. It is integrated with Home Assistant via ESP32 and RS232, alongside a homemade 24V 400Ah battery using BMS, enabling advanced energy automations based on grid, PV, and load monitoring.
