The Sunny Boy line of inverters are applicable for 700 W to 1 MW of PV grid tie power with a conversion efficiency > 93%. The basic principle of the Sunny Boy inverters is that one inverter is used per string of modules; where typical configurations use several strings of modules in parallel to achieve rated power, the Sunny Boy uses modules wired in series at a high DC voltage. String inverters are also easily paralleled to increase energy efficiency. The result is increased efficiency and great savings in wire costs, eliminating the losses due to mismatching and the need for a combiner box, blocking diodes, and high current DC breakers or fuses. UL listed and CE certified.

If you need monitoring, nothing could give you more options than the Sunny Boy inverter and control unit. The inverter can be purchased with a two line LCD display with backlight that will give you all the relevant PV data (model SBD). The inverter also automatically reads real time data, at a 132.45kHz frequency, over the 60Hz sinewave. This is called power line transmission, and it means no additional cabling needed. To input this data into a PC, buy the SWR-COM socket modem that plugs into any outlet and broadcasts the power line transmission to a PC com port. Supply voltage, 0-260V, 50-60Hz.

Data logging requires purchasing one of the three control units, the Sunny Boy Control Light, the Sunny Boy Control, or the Sunny Boy Control Plus. The control units can either receive data via the power line transmission, RS232 or RS485 connection. The control units will allow you to store data from 1 to 50 inverters, monitor the data and, via an external customer supplied modem, send data or fault alarms to an email, a FAX, or a pager. LCD display. Ambient temperature 0°C to 40°C. Software to monitor either the inverter power line transmission output or the control unit’s output is provided free of charge. The software provides an excellent GUI for monitoring small, 5-module systems to large-scale power stations.
