PMO-40, C40k & VLC40 for Sinewave Systems
3. Route all battery temperature sensor (BTS) cables through the opening
in the tray of the module at the bottom right rear behind the DC disconnect
breakers. This allows the BTS cables to be routed along with the battery
cables. There may be multiple temperature sensors depending on the
number of charge controllers and inverters in the system. Utilize all
available temperature sensors to maximize system performance. Connect
the temperature sensors to the charge controllers through one of the
openings in the rear of the PM with a plastic grommet protecting the edge.
Place all temp sensors on the same battery and in the middle of the battery
bank.
The top view illustrates the installation, mounting, and cabling of the C40
option looking toward the right-hand cabinet panel. The C40 multipurpose
controller has three modes: PV charge control mode, DC load control
mode, and diversion load control mode (the controller can operate in only
one mode at a time). In addition, the C40 option includes a 60-amp
Heineman™ DC breaker, #6 AWG wiring with ring terminals, and all
mounting hardware. A 24-page operating manual for the C40 controller is
also included. The VLC40 is a voltage limiting controller. It includes all of
the items that come with the C40, but uses a modified C40
for systems that use PV modules generating high
open-circuit voltage (over 70 volts DC) without batteries.
The VLC40 automatically limits voltage to less than 70 volts
DC. The PMO-C40K installation kit includes everything that
the PMO-C40 includes except the C40 and the C40
operating manual.
