E3DC GmbH

Reads energy and battery values from E3DC storage inverters via Modbus TCP.

Overview

This ModbusCloud template reads PV power, battery state of charge and power, grid power, consumption power, and emergency-power status from E3DC storage inverters over Modbus TCP. It covers S10 Mini, S10E, S10X, and S10E Pro models with PV peak performance from 7.5 kWp to 20 kWp, returning signed int32 power values and uint16 status flags.

Key readings

PV Power
Battery SOC percent
Battery Power
Power energy provider
Emergency-Power status
Consumption Power

Use cases

Show grid import vs export on a clear dashboard to help the customer understand their self-sufficiency ratio.
Alert on emergency-power activation so the installer knows the battery kicked in during a grid outage and can log the event.
Log daily battery cycles by tracking state of charge over time for warranty and degradation analysis.
Compare PV production against home consumption to suggest the right time to run large loads like dishwashers or EV chargers.

Installation

1Log into the S10 web portal and enable Modbus TCP under the network settings.
2Note the S10 IP address and set a DHCP reservation in the router.
3In ModbusCloud, add a Modbus TCP device at the S10 IP, port 502, slave ID 1.
4Import the E3DC Inverter template. Power readings appear immediately, typically within one polling cycle.
