My inverter failed 4 weeks ago. Got an 18xB7 hw error message. No solar at all. My inverter only shows 5 of 31 panels and re-paring the system has not resolved the issue. I was charging the car and it shut down. Contacted Tesla. Was told it takes 3-4 weeks to get an inverter. I’m not holding my breath as the last time they sent someone out to fix my gateway connection issues, it took them 4 months to send someone out. Anyone experienced this type of failure?
