# Known Issues

Issues have been reported with data; these vary by firmware version. Newer firmware may resolve these or introduce new issues.

## Production & Consumption data

## Inverter device data

The inverter device data includes a `deviceDataLimit` that appears to be fixed at 50. If more inverters are installed, only data for the first `deviceDataLimit` inverters is included, resulting in missing inverter data. When the reported `deviceCount` is greater than or equal to `deviceDataLimit`, data falls back to /api/v1/production/inverters to avoid data loss; device detail data will then be unavailable for all inverters.

Std: Envoy standard (not metered). Mtr: Envoy metered. NoCT: Envoy metered without installed and configured CTs.
