8.4.1 Parallel Solar Systems
Two or more solar systems can be directly ORed together using a splitter cable.
Using the Solar Supply in parallel provides a modular approach to incrementally increase the capacity in some challenging
applications or locations.
1. BWA-SOLAR-001. FlexPower Solar Supply, includes
panel, solar controller, rechargeable batteries, and
mounting materials.
2. DX80N... DX80 or DX80 Performance FlexPower
Node or 10–30V dc Node.
3. Power Splitter Cable, quick disconnect, 5-pin Euro,
female trunk, male branches.
8.4.2 Battery Backup Feature
The DX81P6 6-Pack Battery Supply Module can operate as a power backup for the FlexPower Solar Supply when the units are connected
using the splitter cable..
The FlexPower Solar Supply can be ORed with the DX81P6 Battery Supply Module using the CSRB-
M1253.28M1253.28M1253.28 splitter cable. When the solar panel temporarily disconnects the load because of a lack of
sunlight, the DX81P6 Battery Supply Module supports the system and powers the load. This battery backup can support a
sensor system consisting of a 2-wire transmitter powered continuously with 15V at 20 mA and a DX80 Node transmitting
once per second for up to 30 days.
Optional mapping allows a battery backup function to be mapped to a wireless error output to determine if the devices are
powered by the solar panel assembly or the battery supply module.
8.4.3 Autonomous Process Monitoring with Continuous Sensor Operation
A single FlexPower Solar Supply can supply any continuously powered 4–20 mA, two-wire transmitter at 13V and power the DX80 Flex-
Power Node for continuous sensor operation.
This application requires at least 1.7 hours of sun per day and the battery provides about 10 days of autonomy with a full
transmitter signal of 20 mA. Marginal solar situations can be supplemented with a DX81P6 Battery Supply Module acting as
a battery backup unit to add an additional month of autonomous operation.
The FlexPower Node’s boost converter provides an adjustable continuous 21V courtesy power output.
1. BWA-SOLAR-001. FlexPower Solar Supply, includes
panel, solar controller, rechargeable batteries, and
mounting materials.
2. Pressure Transmitter, 4-20 mA, two-wire.
3. DX80N9X2S-CS1. FlexPower Node for continuous sen-
sor operation.
