Murph, So what's your system look like? I have the DC Solar trailer config with dual SI-6048s looking to add the SI 7.7 GT inverter and probably a 10k +- array. In Pacific NW so winter-time isn't great, but that's life. Thought was to use AC coupling to augment the SBs in off-grid fashion...

The current configuration is a DC Solar trailer with dual 6048s and 2.4kw solar as an off-grid config. This trailer uses a diesel generator as backup to the solar. The off-grid package connects to a transfer switch inside the house/garage. It is never connected to the grid. The main panel is...

Thanks sir. I don't want to hijack the discussion but thought since y'all were on the topic I would ask. In my case, by 6048's are used in off-grid (backup) fashion and only connected via transfer switch in the main breaker panel when the power goes out and not connected to the grid. The...

Hedges - So will the SMA 7.7 GT inverter freq shift properly if paired with the SMA SI 6048s, or will there be problems due to the 6048s being UL-1741 but not UL-1741SA? Looking to add some AC-GT and would like to know if these will play nice together. If not are there other/better options are...

Greetings all, On the trail for the latest experience / info on expanding an existing off-grid backup system. Current system is a paired set of Sunny Boy SI 6048-US-10s with battery backup and generator (DC Solar trailer setup). This goes into 2 separate panels via transfer switches - one to...
