I've a Morningstar 60 Charge Controller and it started giving an HVD (High Voltage fault) yesterday. The operation manual gives the definition but doesnt describe the solution. Dunno what is causing it or what to do about it. Manual says it is in diversion mode, so I thought it is doing its job, right? But then it says that faults left unresolved can cause serious problems. Does anyone know the resolution? Happens only during the day when sun is at peak and I am not using much power now since I only have a small 400 watt inverter to power the laptop and nothing else. Also this brings up an important point. I really need to be better equipped to manage these things. Is there a book?
