How to Connect Solis Inverters with the e-WNDR App

This integration is currently in Beta. It works for most SolisCloud systems, but you may still come across rough edges.

Preconditions:

  • You have a SolisCloud account (the account you use in the SolisCloud app or on soliscloud.com).
  • Your inverter is visible and online in SolisCloud.

Connecting Your Solis Inverter with e-WNDR

  1. Open solar/inverter setup in e-WNDR and select Solis.
  2. e-WNDR opens the SolisCloud login page. Sign in and approve access.
  3. Back in e-WNDR, select which of the discovered devices to connect.

e-WNDR asks for both data access and device control permissions, so that battery control is available after connecting.

Supported Devices

For every inverter found in your SolisCloud account, e-WNDR creates:

  • an inverter,
  • a meter, derived from the inverter’s net grid power and home consumption readings,
  • a battery, if the inverter reports one.

Features and Things to Know

Once connected, you can:

  • Monitor live PV production, grid power, home consumption and battery state of charge.
  • View historical data at 5-minute resolution, collected hourly and when you open the app.
  • Use Autopilot to charge and discharge your battery. When a requested charge or discharge period ends, the inverter automatically returns to its normal self-consumption mode.
  • Switch devices on excess solar production with Autopilot (Solar Mode).

Home consumption comes from the inverter’s own load reading. If your system has both a grid load and a backup/EPS load, only the grid-side load is currently used.

Troubleshooting

  • If SolisCloud returns a “feature restricted” or “forbidden” error, your account or plant is not enabled for this API on the Solis side. Please contact your Solis installer or Solis support.
  • Solis rate-limits its API. Occasional gaps after many rapid refreshes are expected and resolve on the next collection run.

Meter type

  • Main meter: Grid meter. Can be configured as bi-directional or consumption.
  • Production: Measures solar production. Configure as sub meter with type production.
  • Sub meter: Measures any type of device as a sub meter and appears in device consumption.
