Sunny Boy Set Up
NOTE: When using Sunny Boy inverters together with the Sunny Island 4248U, it
is recommended that the battery bank contain at least 100 Amp hours of capacity
per 1000 W of PV modules installed. For example, if there is a pair of SB2500U
inverters and 5 kW of PV, the minimum recommended battery capacity would be
500 Amp hours.
Off-Grid Systems
If you’re using Sunny Boy inverters in the system you will need to set the Sunny Island 4248U
to interface with the Sunny Boys. You will also have to set a parameter in the Sunny Boys to
work with the Sunny Island 4248U.
To prepare the Sunny Island 4248U for use with Sunny Boy inverters, set the “SunnyBoys”
parameter to “YES”.
On the Sunny Boy(s), set the “Default” parameter to “off grid”.
Back-Up Systems
In both Back-Up modes, ("GridConnected" set to "GridCharge or set to "Grid-FeedPV"), the
Sunny Island 4248U will disconnect from grid, if the voltage or frequency is out of the ranges
defined by UL1741 (as shown in the table below).
