Technology: BOS Architecture: System Monitoring Overview Monitoring the RETS using one or more varieties of digital and/or analog monitoring devices is as important as the dashboard on a vehicle. These devices provide important status of the operations of the RETS deployed. A good number of charge controllers have indicator lights and readouts built-in which offers adequate information of the charge and voltage available for the system. For a full-scale remote home, consider the addition of a digital monitor, like Trace TM-500, Tri-Metric, E-Meter or Omni-Meter. These devices monitor voltage and current, record amp-hours, and accurately display the state-of-charge of the battery bank. More importantly, some monitoring devices also record or log more detailed information that can be useful for troubleshooting. Often, the monitors are designed such that they may be mounted in another room or building, for remote viewing and monitoring. Direct monitoring of the health of the batteries in the battery array can be performed with a hydrometer. A hydrometer will help determine whether the battery bank is getting fully charged, and whether any individual cells are falling behind, useful in adjusting the array to deliver equalization and charging equally. Hydrometers are, unfortunately, prone to false readings under certain conditions such as taking a reading immediately after adding water to the battery, or taking readings during low ambient temperatures, and therefore, the user must ensure that proper conditions exist and proper procedures are followed to ensure accurate readings. Hardware As the renewable energy market develops and evolves, new products appear offering more detailed, and more data to promote more accurate readings of the status of the renewable energy technologies deployed. The following describe currently available separate monitoring devices (i.e. devices not built-in to charge controllers). As more products become available, the descriptions below will expand. SWC does not endorse the hardware products described below, and are listed and described purely for informational purposes only.
Software With new monitoring hardware appear in the market, software systems which enhance the usability and functionality of the monitoring devices also begin to appear. The following describe currently available software monitoring applications. However, given the relatively immature state of renewable energy technologies, devices developed are proprietary (i.e. will work only with a specific vendor's hardware) and therefore, the software applications are also designed to augment the proprietary monitoring hardware. As more software applications become available, the descriptions below will expand. SWC does not endorse the software products described below, and are listed and described purely for informational purposes only.
