Ingeteam SUN STORAGE 1Play TL M

Compatibility

Compatible with EpiSensor Edge over Modbus TCP

Ingeteam's 1Play input-register document ABH2010IMB02 defines the online data as input registers read with function 0x04, numbered from 30001 at memory position 0. The 1Play TL M manual states that the inverter's EMS uses Modbus-TCP on port 502 and sets the polling limits. Edge is a Modbus TCP client and reads those registers directly.

INGECON SUN STORAGE 1Play 3TL M, 4.5TL M and 6TL M under input-register document ABH2010IMB02 revision K and manual ABH2014IQM02 revision A. Site check: read the battery block at 30015 to 30018 and compare voltage and SOC with the web application. Poll no faster than once a second and no more than 10 registers per request. The RS-485 port serves the inverter's own wattmeter, not Edge. Read-only monitoring; no charge, discharge or export settings.

Setup

1. Identify the model and firmware

   Record the rating from the nameplate (3TL M, 4.5TL M or 6TL M), the inverter firmware and the battery. The register map gives the firmware version from which each register exists, so check the firmware before polling status and battery status.

2. Connect the inverter to the network

   Use the Ethernet TCP cable on connector J10 or join the inverter to a Wi-Fi network from the web application. The inverter uses DHCP by default; reserve its address or set a static one.

3. Check for an existing client

   Ingeteam recommends a single client on port 502. If a monitoring or EV charging system already polls the inverter over Modbus TCP, agree with its owner before Edge connects, and keep the combined request rate within the manual's limits.

4. Read the battery block

   Create a read-only Modbus TCP connection to port 502 and read four input registers from 30015 (wire address 14) with FC04. Read the Modbus node from the inverter's communication settings. Apply V x 10 to voltage, A x 100 to current, W to power and % to SOC.

5. Add PV, grid and load points in small blocks

   Group the remaining reads into blocks of no more than 10 registers, for example 30024 to 30031 and 30033 to 30040, polled every few seconds rather than continuously. Record the sign of battery and grid power during an existing charge and an existing export.

Common questions

Can Edge use the 1Play RS-485 port?

No. The RS-485 port connects the inverter's external wattmeter for self-consumption. Edge reads the inverter over Modbus TCP on Ethernet or Wi-Fi instead.^2, 3

Why does the inverter stop answering when I poll fast?

The manual recommends one client on port 502, at least one second between requests and no more than 10 registers per request; otherwise correct data is not ensured. Split the map into small blocks and slow the poll.³

Which register gives the battery state of charge?

Input register 30018 (wire address 17), UINT16 in %. State of health is the next register, 30019.¹

Why does Inverter Status read zero on an older inverter?

The map gives a since-firmware version for each register. Inverter Status at 30013 is listed from firmware _W and battery status at 30022 from _Y, so older firmware may not serve them.¹
