NOTE: Batteries are not supplied with this panel and must be purchased separately.
The SPB-320 requires four 12V batteries UL rated up to 33Ah. The enclosure can accommodate
up to 12Ah batteries. Two are wired in series to each SPB-160 module.
Run the battery wiring across the top of each power supply (SPBPS) and down the right side of
the power supplies to the batteries.
Figure 4-27 shows the correct setup of the batteries inside the cabinet, the location of the jumper
wires used to connect two batteries in series, and the location of the battery terminal connections.
