Connecting DC Input Sources – Renewable Energy Configurations
Renewable energy sources (e.g., PV arrays, wind turbines etc.) may
require additional equipment such as charge controllers, diversion load
controllers, PV Ground Fault Protection, and additional fuses and/or
disconnects. Since every configuration is unique, specific installation
instructions cannot be provided. Follow your manufacturer’s instructions
for installation of these components.
Be sure to consult your local authority to ensure code compliance for your
configuration.
Installing the Battery Temperature Sensor (BTS)
Install the sensor on the side of the battery below the electrolyte level so
as to measure the average battery temperature. If using multiple charging
devices (inverters and charge controllers), install all sensors together with
each other so they all measure the same temperature. It is best to mount
the sensor(s) between the batteries in an insulated box to reduce the
influence of the ambient temperature outside the battery enclosure.
Ventilate the battery box at the highest point to prevent hydrogen
accumulation.
To install the BTS, follow the steps below.
1. Run the BTS wire in the DC conduit (if used) and route the RJ11
connector end (via one of the knockouts) to the BTS port located on
the DC end of the inverter.
2. Secure the sensor to one of the batteries located in the center of the
battery pack.
3. If other devices are using battery temperature sensors, place all of
them on the same battery so that they all measure the same
temperature.
