Detailed Description:

Works with ASNET and Modbus Enabled Products

The Gateway can work with either products that use Apollo's original ASNET network bus or with the newer industry-standard Modbus enabled products.


  • Allows data from all Apollo Solar ASNET or Modbus enabled products to be monitored via Ethernet
  • Sends data to our server for monitoring using any PC.
  • 1 year of AMS Apollo Monitoring Service included.
  • Compact low-power Serial-to-Ethernet Gateway
  • Monitor all your Apollo Solar devices from any computer via the web
  • See current and historical energy harvest
  • Diagnostic data from each device
  • Check PV, battery and load profiles

Works through the Internet or Locally

By default, the Communications Gateway automatically sends data from connected devices to Apollo's server, where you can use any browser to go to Apollo's website and monitor the performance of your Apollo products. If you don’t have a broadband connection to the Internet, Apollo offers a PC program you can install to monitor locally.

Easy Installation

The Communications Gateway is preconfigured with all the information it needs to connect to Apollo's server. Simply connect the included cable to any one of your Apollo products, and plug a conventional Ethernet cable between the ACG-1 and your broadband router.

Indicator Lights Show Status

The Gateway includes indicator lights to show serial and Ethernet activity to confirm proper operation.

Accessories Add More Communications Options

If you prefer to communicate using WiFi, the Apollo Communications Gateway works with Apollo and third party WiFi bridges to let you use WiFi instead of wired Ethernet. For industrial and telecom applications we offer the GSM modem to communicate using GSM networks. See the Apollo Cellular Modem ACM-1.

Frequently Asked Questions
  • How many T80 charge controllers can be monitored from one Gateway?

    Up to 31

  • How many TSW inverters can be monitored from one Gateway?

    Up to 31

  • How many total devices can be monitored from one Gateway?

    Up to 255

  • How often is data sent from the Gateway to the server?

    The server asks for data from a device every six seconds, or 14,400 times a day. If there is one T80 in the system, then there is data from the T80 every 6 seconds. If there is a T80 and a TSW inverter, then there is data for the T80 every 12 seconds and for the inverter every 12 seconds.

  • Does the Gateway have to be powered from the included AC power supply?

    No, the Gateway can receive power from the T80 or TSW.

  • Does the Gateway have to be programmed or setup?

    No, the Gateway is strictly plug-and-play.

  • How can I tell if the Gateway is communicating with the T80 or TSW and sending data to the Internet?

    Refer to the Gateway user guide for detailed information, however if the Transmitting Serial LED blinks every 6 seconds then the Gateway is communicating with the server. If the Transmitting Serial and Receiving Serial lights are blinking every 6 seconds then the Gateway is communicating with the server and with the attached Apollo devices.

  • Can a user use software on a local PC to communicate and get data from the Apollo devices using the Gateway?

    Yes the Gateway will accept incoming requests. Apollo can provide sample code for communicating on a local network.
