Battery And Pv Wiring - BLUE SKY SB3000i Installation And Operation Manual

Blue Sky Energy – Solar Boost 3000i

BATTERY AND PV WIRING

A desirable installation will produce a total system wiring voltage drop of 3% or less. The lengths shown in Table 3 are one way from the PV modules to
the battery with the 3000i located along the path. Length can be increased inversely proportional to actual PV I
wire lengths could be doubled and still provide the same 3% voltage drop. For 60 cell modules use two wire sizes larger than shown (e.g., 8awg rather
than 12awg) for the wire section between the 3000i and the battery.

➢ CAUTION: Battery and PV compression terminals accept #16  #8 AWG wire and are to be tightened to 15.9 in-
lb (1.80 nm). Temperature Sensor and IPN Network compression terminals accept #2616 AWG wire and are to
be tightened to 2.1 in-lb (0.24 nm). Take care to route wires in a manner that does not place undue strain on the
3000i's compression terminal blocks.
