Hello everyone, We are facing a serious firmware-related issue with two Livoltek Hyper 5000 hybrid inverters installed in Colombia. These are the affected serials: - HP10503HSA300139: Failed completely after firmware update; unit had to be replaced. - HP10503HSA300261: Works partially. It charges batteries (4 × 12V 150Ah in series) but never discharges to load, even in Self-Use or EPS mode. Key symptoms: - SOC stays at 0% constantly, even after a full day of solar charging. - DRM cannot be disabled. - The house icon in EPS mode is not shown. - Battery discharge is completely ignored by the system, including during grid failure. - Firmware update left it in Backup logic, and reconfiguring Self-Use mode does not fix the behavior. We suspect a firmware or batch-level fault. A third inverter from a different batch (HP10503HPA510143) works perfectly in the same conditions. We are seeking help from anyone who: - Has encountered this problem. - Knows how to reflash Livoltek firmware or unlock engineer access. - Can confirm known firmware issues with this model. Thanks in advance for any guidance or experience shared. Jhovanny Botero – SGC Ingeniería Eléctrica SAS (Colombia)
