Information on GoodWe inverters

It is mandatory to upgrade the ARM and DSP firmware version of the DT and MT model inverters to the latest version before installing the Teleport. If the Goodwe inverter firmware upgrade instructions are not available to you, GoodWe or Withthegrid can share the relevant documentation. Teleport might not be able to connect to inverters with old firmware.
Goodwe DT and MT model inverters with updated firmware we have seen often exhibit communication problems. For DT models, expect that up to 20% of the time data readout is not available and that control commands can take up to a minute to be applied. Both MT and DT models occasionally become unavailable for readout and control for one or more full days (while they continue to produce power). Inverters typically recover during the daily automatic reboot or by doing a manual reboot. Goodwe recommends updating the firmware to fix this behavior, but we have not seen a positive effect of that yet.

We do still support projects with DT and MT models, but we will not actively monitor the asset connectivity of those models.

On inverters in the -DT-series (ending in -DT), it is not possible to read out the setpoints after curtailment commands, since sending this information is not supported by these models
On GoodWe inverters that are linked together the last inverter in the string has to have a 120 Ω termination resistor dip switch, which is ‘ON’. This switch can usually be found underneath the RS485 connector (so the RS485 connection has to be unscrewed).
If only one or several inverters in the string become unavailable for readout and control, no reports will be generated because we do not construct partial reports.
If one or several GoodWe inverters become unavailable for readout and control, curtailment is still possible for the remaining inverters in the string.
GoodWe inverters with the same name can differ in their actual physical appearance. For example, whereas the manual may state that no LCD screen is available, it may be available, or vice versa.
If no LCD screen is available, the SolarGo app can in most cases be used on a smartphone to connect to the inverter and log in to the menu.

Connect the serial cable between the serial port of the Teleport and the serial port of the Goodwe inverter. In the case of multiple inverters in a series connection, the first inverter in the line needs to be connected to the Teleport. The Teleport can support up to 3 strings of inverters. Each string can be connected to main module, module A or module B
Note down and share with us the individual slave ids of each inverter. Make sure that all inverters on a single string have a unique slave id. A slave id can be found on the inverter’s LCD display as follows:
- Hit Enter to go to settings. Scroll down with the UP/DOWN keys until Set Modbus is selected.
- Hit Enter and select ADDR:XXX . This is the slave id.
- Hit Enter and use the UP/DOWN keys to change the slave id (address). In the case of one inverter, this number should be 1. In the case of multiple inverters, please set each inverter to a different address and let us know these addresses.
