Atmoce MG100 M-gateway

← PV, Battery, Grid, Meter

Support for Atmoce MG100 (included with MC100 and MC100-T). Requires installer to enable Modbus TCP in configuration or through Atmozen app; available in firmware 01.01.00.18.10 or later. 'Grid Recharging' and 'Export Power' must be enabled in the Atmozen app to allow battery (dis)charging to/from grid.

Supported features

Battery control: External control of home battery charging and discharging via evcc.
Curtailable: Inverter production can be reduced (e.g. § 9 EEG). See External Limit.
Dimmable: Power consumption can be reduced (e.g. § 14a EnWG). See External Limit.

Parameters

Name	Description	Value	Level
`id`	Modbus ID Default: `1`	int	required
`host`	IP address or hostname Example: `192.0.2.2`		required
`port`	Port Default: `502`	int	required
`capacity` [kWh]	Battery capacity Example: `50`		optional
`maxacpower` [W]	Maximum AC power of the hybrid inverter Default: `0` Example: `5000`		advanced
`minsoc` [%]	Minimum charge Lower limit when discharging the battery in normal operation Default: `10` Example: `25`		advanced
`maxsoc` [%]	Maximum charge Upper limit when charging the battery from the grid Default: `100` Example: `95`		advanced
`maxchargepower` [W]	Maximum charge power For forced charging of the battery.		advanced
`maxdischargepower` [W]	Maximum discharge power Maximum discharge power of the storage.		advanced
`firmware`	Firmware version Firmware 01.01.00.28.15 and higher allows for correct hold/holdcharge functionality, dimming and curtailing. Older versions only support hold function without (dis)charge. Default: `<01.01.00.28.15`		advanced
