I would like to highlight a few key points from today: I) I have added you to the SMA Sunny Portal where you can login via smartphone or PC to review plant stats. Please follow the directions in your email box. 2) Conditioning the inverter room: We discussed multiple ways of using fans instead of air conditioning but at the end of the day eliminating moisture and salt air is more important than heat dissipation since the inverters draw in corrosive air 24/7. Heat IS a problem and the inverters will be more efficient if the space is cooler. I would recommend walling off half of the room, insulating the roof with spray foam, and installing a lton high efficiency split unit to keep the temperature at 78 and dry. The room needs 2 doors(extra for fire code) that can be locked. We checked the inverter logs and found multiple de-rate error codes(Error W137) indicating loss of efficiency from high temperatures. 3) Existing R.O. System: We are experiencing a major draw at 2AM. I do not know what the draw is but it needs to be investigated. We could install a circuit level monitoring device on the main load center in the basement of the main house which would tell us how much power each load is drawing. Until this high load is located and eliminated I do not recommend a larger R.O. System. EFTA01041588
