INVERTER ISSUE: PROBLEMS WITH OUR ALPHAESS SYSTEM FROM HEATABLE AND HOW THEY WERE RESOLVED

EV Channels Review

This video details the troubleshooting and resolution of two primary issues encountered with a Heatable-installed Alpha ESS solar and battery system. Initially, one solar string was not functioning, and a secondary problem prevented significant export to the grid once the battery reached 100% capacity. The reviewer highlights the proactive communication between Heatable, the installers, and Alpha ESS support. The solar string issue was diagnosed as potentially software-related but ultimately attributed to an inverter fault. The parallel export issue was identified as a known problem with Alpha ESS systems configured in parallel, for which Alpha eventually provided a firmware fix. The reviewer praises the UK-based support from Alpha ESS and the efficiency of Heatable in addressing the problems. The resolution involved swapping out a faulty inverter and a subsequent firmware update, which restored full export capability, leading to 'negative bills' on some days. The video also touches upon the process of obtaining the export MPAN from UK Power Networks, which took a considerable amount of time.
