I've installed my LVX-6048 with 4kW panels (8S2P 250W) and split-phase 240V AC input. As I'm in Mexico, UL compliancy is not required for my home here (yet), so I'm exporting energy to the grid. Everything works well except when the sun goes down and the panel voltage goes to zero, the unit begins to beep and display error code 52. Turning off the unit clears the alarm, but unless there is some current from the solar panels, the error code returns, and there is a 'thumping' that takes place until I turn off the unit. So, every morning after the sun begins to rise, I can switch the unit back on. I've yet to install a battery, which may correct the issue. But I'm not sure that's the problem?
Does anyone know exactly what 'bus voltage too low' means?
