 Product Description

NOTE:  This product is not yet shipping, and is only available for preorder.   We expect this product to begin shipping in February 2020.  Limit 2 pre-ordered items per customer.  The price shown above is the pre-order price.  The normal order price will likely be somewhat higher.

If you are looking for the existing (SiteMonitor Base II) product, it is available here

Our SiteMonitor products permit the monitoring and control of equipment at any site which has IP connectivity. Designed to provide low-cost monitoring and control, the SiteMonitor products are the perfect addition to any remote site, or to any supported equipment you want to be able to monitor and control.  This is the newest version of our SiteMonitor Base Unit, the Base Unit 3.   It contains a brand new web interface designed from the ground up to be mobile-friendly and easy to use, and several other new or refreshed features better described below.   

Customers who already have a SiteMonitor system with an earlier Base Unit will find that the SiteMonitor Base 3 - Classic Edition is electrically compatible with existing systems.  This means that no re-wiring will be necessary to upgrade sites to the Base 3.  In addition, existing expansion modules will be able to be used directly with the Base 3.  Initially a limited type of modules will be supported.  Additional firmware will be released over a few months to support most, if not all, of the existing modules in the field.   A release note will be available in November which details compatibility with existing modules and configurations.

The Base 3 acts as the foundation of the SiteMonitor system, with a 10/100  Ethernet interface to connect to a TCP/IP-based network.   In addition to the web interface, it also accepts SNMPv1 or SNMPv2 queries to permit monitoring and control of all attached devices.  

The Base Unit II includes a few built-in inputs and outputs. The built-in functionality was designed with a small solar site in mind. For many sites, you may only need the Base Unit II.  However, if you need more capabilities, there are numerous expansion modules available which are connected via the expansion port.  There are numerous modules available including remotely-controlled PoE Injection, Cambium Compatible Synchronization, additional analog and digital I/O and also monitoring of other devices such as Solar Charge Controllers and UPS'es.   If you don't find a module which fits your needs, feel free to contact us so we can either point you to the right module, or perhaps build a specialized expansion unit for your particular application in the future.

The Base Unit 3 Classic Addition has the following inputs:

  • Dual Polarity Agnostic 12-56VDC power inputs, each metered separately - plug one into a battery-backed source, and one into a line-powered adapter, or hook it up to any other power source(s) you'd like. The unit will run off of either one, and you will get an indication of the voltage (if any) from each.   "Polarity Agnostic" means you can now run this unit off of positive ground/negative voltage systems like the common -48VDC at a communication site.   Each of these inputs can also be jumpered such that it is only a voltmeter for monitoring voltages which shouldn't be used to power the device.
  • 10/100 Ethernet Input.  This input also supports PoE via passive PoE injectors. 
  • DC +-100mV low or high side shunt input. In DC applications, add a shunt to your system, and receive an indication of the net current through that point in the system.   (Does not support placement in the -48VDC line on a -48VDC system).
  • Resistance input. This flexible input replaces the 'switch input' on the previous version.   The updated version can not only connect to a switch closure such as a security loop, or a switch or relay closure output, but also to resistive sensors including temperature and tank level sensors. Perfect for detecting whether the door to your equipment has been opened or whether the security loop through your solar panels is intact.
  • Relay Output. Control up to 2A at up to 30VDC or up to 60W DC at voltages above 30VDC. Perfect for switching a remote load (such as a radio) on and off. 
  • Internal Temperature Sensor. There is an on-board temperature sensor built right in. Read an approximate temperature of the enclosure the SiteMonitor Base Unit II is in so you can be alerted to heating and cooling system failures.

Some key additional features include:

  • DIN Rail Mountable
  • Ultra Low Power consumption - Less than 1 Watt typical.
  • Industrial Temperature Range - Good down to -40C/F and up to well in excess of 60C/140F.
  • SNMPv1 and SNMPv2 support
  • Web-First, Mobile Friendly web interface for configuration and management
  • Internal Watchdog timers to ensure continued availability.
