Janitza UMG, Siemens PAC 2200, neoom BEAAM

Part of the compatibility overview, which lists every selectable Mains type.

• Janitza UMG: reads the float block from register 19000 (UMG 96RM, UMG 604 and compatible). Total and per-phase power, currents and voltages.
• Siemens PAC 2200 (Modbus TCP variant, e.g. 7KM2200-2EA30-1JA1): from firmware 2.5.0 the station reads total and per-phase active power and currents via Modbus TCP (port 502, unit ID 1). Voltages are only used to check the register mapping and are not shown. Leave the meter's Invert current parameter at its default (no); the station converts the PAC's sign convention itself. Up to firmware 2.4.x the values are decoded incorrectly (readings around ±2 billion), so update the station before commissioning.
• Siemens PAC 2200, check after commissioning: when a charging session starts, the grid draw shown by the station must rise (or the feed-in fall) by roughly the charging power. If it moves the other way, the current transformers are mounted in reverse. On MID-certified units the direction cannot be inverted in the meter, so the wiring must be corrected.
• Siemens PAC 2200: the updated driver is still in its first field test. Contact eCharge support before planning a new installation with this type.
• neoom BEAAM: grid values from the gateway's Modbus TCP server.
• None of the three delivers battery values.
