Will the Sunny Island mate up with these Sunny Boys that have the
limited backup capability during an outage, as they will with
standard Sunny Boys? Thank you, Allan ------- Original Message --------
Hi Carl and All, This spring we had the opportunity to install a 5000-TLUS inverter for a client, as a pre-release version. The inverter was commissioned on April 1st and has produced about 2.7 MWhs thus far. As mentioned, the secure power supply (SPS) requires a dedicated outlet with a switch to control its operation. For this installation we installed the SPS in the mechanical room, which is about 50 ft from where the inverter is located. We chose the mechanical room because it is centrally located within the floor plan of the home, making it easily accessible to plug in emergency type loads, i.e. cell phone chargers, laptops, lamps, etc.. It is also very close to the fridge, which we plugged in with a short extension cord and tested its operation in the "stand-alone" mode (which is what the inverter display when the grid is down and the SPS in activated). The inverter had no problem powering the fridge. The inverter display showed about 900 watts bypassed from the solar array to the SPS when the fridge cycled on....I must say it was a very cool feeling seeing this happen. As far as the inverter itself goes, I only have a few minor complaints. Like the old SMA 1800U and 2500U, the conduit knockouts on the bottom of the inverter are at a slight angle, which means you must put a slight bend in your conduit. This is obviously a bit annoying and I can only guess it has something to do with the plug and play nature of non-U.S. installation techniques. The TLUS inverters are also lacking Bluetooth communication, unlike their HFUS counterparts. I think this is a nice feature of the HFUS inverters and wish it was integrated into the TL's. With no real difference in cost compared to traditional grid-direct inverters, I see no reason not to specify the TL, especially for someone who has a desire for "limited" power supply during a grid outage. They can always add a Sunny Island later on, if a more robust backup system is needed. I hope this helps.

Do they have a representative on the list?
