Using Two Power Sources
Using the Solar Supply with a Battery Backup
A common configuration with solar panel installations is using an additional battery module as a backup to the rechargeable battery pack
installed inside the solar power assembly. The following example shows how to connect the DX81P6 Battery Supply to a solar-powered
system. (The solar panel does not recharge the DX81P6.)
FlexPower Node or
FlexPower MultiHop Radio
Splitter Cable Model: CSRBM1253.28M1253.28M1253.28
Part Number: 13805
Splitter cable for dual power sources, 5-pin Euro-style
female trunk to two 5-pin Euro-style male branches.
The trunk and each branch are 1 meter long.
DX81P6 Battery Supply *
BWA-SOLAR-01 Solar Supply
with rechargeable battery pack.
Typically used to connect the SureCross Solar Supply
and a DX81P6 Battery pack to a single SureCross
FlexPower radio.
* Do not use the DX81 Battery Supply Module for this
configuration.
You may also use a conventional 12V solar panel to supply power to a FlexPower Node or FlexPower MultiHop Radio. Just wire the power
out of the solar panel to the brown wire of the FlexPower Node or MultiHop Radio. Wiring the solar panel’s ground to the blue wire.

Powering the MultiHop Radio with a 10–30Vdc Power Supply and Battery Backup
In this configuration, the 10–30Vdc power supply is powering the FlexPower MultiHop radio. The DX81 Battery Supply Module acts as a
battery backup to maintain operation of the MultiHop radio during a power outage. With the MultiHop radios, you can read a register to
determine if the radio is running off 10–30V dc or a battery supply.
