DC disconnects and
over-current devices
The size of the bonding jumper must be the same gauge as that of the
primary battery cable in which the overcurrent device (DC disconnect) is
installed, and as always, the overcurrent device must be sized
appropriately for all cables attached to it. If one overcurrent device trips
then there will be only half the amount of current available for both
inverters to run from. If you want to run only one inverter while the other
is shut down (for example, for maintenance procedures), the positive
bonding jumper must be removed or there must be an appropriately sized
switch installed in the bonding jumper.
Battery Temperature
Cold temperatures
Cold temperatures drastically reduce battery capacity and performance.
The battery enclosure, therefore, should provide a fairly stable
temperature for the batteries. If batteries are installed in a cold
environment, insulation should be installed to protect the batteries from
the cold. The insulation will act as a barrier to the cold and also keeps the
heat generated by the batteries inside the enclosure providing a more
stable temperature and better system performance.
Hot temperatures
High battery temperatures greatly shortens the life of the batteries also.
The battery enclosure should not be installed in direct sunlight where the
sun can overheat the batteries. Locate the enclosure where it will be
protected from the sun and provide vents in the top and bottom of the
enclosure to provide air flow throughout the enclosure.
For best performance, locate the batteries where they are in a room
temperature of 20 to 25 °C (68 to 77 °F)
Battery
Temperature Sensor
A BTS is provided with each
Sine Wave Plus
. This sensor can easily be
installed in the system to ensure proper charging of the batteries based on
temperature. Installing a BTS extends battery life by preventing
overcharging in warm temperatures and undercharging in cold
temperatures.
See
“Installing the Battery Temperature Sensor (BTS)” on page 3–18
for
instructions on installing the Battery Temperature Sensor.
