The T-BAT-SYS-HV-5.0 battery system, independently developed by SolarX Energy, is specifically designed for household energy storage and is compatible with the second-generation hybrid inverter of SolarX Energy's A1-HYBRID series, providing household users with a safe and reliable home application solution. This battery uses lithium iron phosphate battery cells and has a safety protection level of Type 4X certified by the National Electrical Manufacturers Association (NEMA) in the United States, maximizing the protection of household electricity safety. When paired with SolarX Energy's single-phase hybrid inverters A1-Hybrid G2 and A1-BI G2, it can form an all-in-one A1-ESS G2 system. It features a modular stacking design with an ultra-thin body of 148 millimeters, occupying a small floor area and supporting floor or wall mounting. It is plug-and-play, shortening the user's installation time. It supports users in conducting remote fault diagnosis through the SolarX Energy Monitoring Platform APP, accessing system data in real time, experiencing intelligent power usage, and saving energy costs.
