Primo 10.0 / strings connected in parallel require overcurrent protection (e.
11.4 / 12.5 / 15.0 g. fusing). Refer to Primo installation manual regarding multi conductor wiring
and fusing details
If multiple strings are connected to an MPP tracker, the string voltages should be
as equal as possible in order to avoid power losses.
