Then, by changing the Group number in the Sunny Beam between 1 and 2, each set of 4 inverters could be monitored separately. NOTE: Only one group of inverters is monitored at a time. For example, if the Sunny Beam is set to Group 1, then only those inverters (up to 4) set for Group 1 are monitored. No data is being retrieved or stored for any other group until the Sunny Beam is set for that Group number.
Sunny Beam Manual Operation Diagnostics The Diagnostics screen provides information on the communication performance of the Sunny Beam and can be very helpful in troublshooting communication issues. When this screen is entered, the Sunny Beam begins transmitting requests for data to the Sunny Boy(s). The Sunny Beam records the successes and failures of these communication requests as described below.
Operation Sunny Beam Manual The Percentages: Displays the success rate of the communication. Ideally this number would remain at 100% indicating that all requests for data were completed. If this number was 50%, it would mean that half of the time the Sunny Beam is unable to complete a request for data with the Sunny Boy. If the number is 0%, it means that the Sunny Beam is unable to communicate with any of the inverters and needs to be moved closer.
Sunny Beam Manual Operation Energy Meter Adjustment The energy meter for each of the Sunny Boys can be adjusted in the Sunny Beam if required. For example, this would allow an inverter used in a previous system to start out at zero, or conversely, restore the values if the inverter was off-line for any reason. & / & 3 ( : . & 5& 3 " % +6 4 5. & / 54 83 )9 4/ 83 .
