Chapter 4: Power Supply

Figure 3: Solar Power wiring

The SCADA 3000 requires 10–15 Volts DC to operate. There are many 12V solar panels avail-

able which will meet this requirement. Current consumption will depend on installed options

such as: voice/modem boards, I/O modules, radio/modem or cellular phone. The batteries

are usually similar to automobile or marine type batteries. Many solar panel dealers also carry

chargers and batteries and can assist in selecting a matching component system. It is important

that the components be designed as a system, otherwise component damage or power loss may

result.
To size the solar panel requirements, use the “Estimating Power Consumption” worksheet a

few pages back, but adjust the value for the Battery Charge Current since the solar panel will

charge the battery and not the SCADA 3000 charge circuit.
