+ | NOTE: there are two distinct versions of the RBC line. Both appear to have PV input limits higher than 25v as found in the older DCC line. Major differences appear to be: | ||
+ | |||
+ | * DS - built-in Bluetooth, support for both 12v/24v banks. | ||
+ | * D1S - no built-in Bluetooth, 12v banks only. Uses traditional DCC case. | ||
