Control devices
Eight independently switchable 12 V outputs for suitable devices. Current measurement and protection features help you monitor your camper electrics.
KNOW WHAT'S POSSIBLE
What E1NS can do.
And what you need.
Core features, suitable add-ons and technical limits – clearly explained.
Built into the E1NS box.
Monitor energy
See battery voltage, current and consumption data in the app. Supports documented 12 V battery types: lead-acid, AGM, GEL and LiFePO4.
Measure temperatures
Two DS18B20 temperature sensors are included in the complete kit. View readings and use them in suitable automations.
Automate routines
Create rules in the app using triggers, conditions and actions. Local automations run without a constant internet connection.
Wi-Fi, LTE and GPS
Connect locally via Wi-Fi. Mobile internet and remote access require a SIM card, data plan, reception and appropriate configuration.
Connect level sensors
Two analogue sensor inputs for suitable 0–3.3 V signals. Tank sensors are additional components; unsuitable signal voltages must not be connected directly.
LIGHTING AND ATMOSPHERE
Your lighting follows the day.
Circadian lighting adjusts brightness and colour temperature to the time of day: bright and white during the day, warmer and dimmer towards evening. Adjustments continue while the lights are on. Switching on later also takes the current time into account.

24 V RGB LED strip connected directly to E1NS: Connect a digitally controlled 24 V RGB LED strip (SPI) to the LED connector on the E1NS box.
RGB/RGBW lighting via Shelly: Connect your 12 or 24 V RGB/RGBW LED strips or lights to a Shelly Plus RGBW PM and connect it to E1NS over Wi-Fi.
Then activate circadian mode for your lighting in the E1NS app. E1NS automatically adjusts brightness and light colour throughout the day.

Leisure battery → E1NS → suitable 12 V devices. The box measures its own branch. Observe 15 A per switched output, 30 A per group of four and 60 A in total.
More power. A wider view.
A large inverter needs its own fused connection. A compatible SmartShunt in the common negative cable supplies battery data to E1NS via VE.Direct. The box's current limits stay the same.
The interactive builder requires JavaScript. You can still read the connection principles and documentation. Open the installation guide →
E1NS distributes a maximum of 60 A.
Up to 15 A per output. Two banks of 30 A each: OUT 1–4 and OUT 5–8.
If your build needs more, the example shows an additional battery branch outside E1NS. The current through the box still stays within 60 A — even with a SmartShunt.
How virtual fuses protect your outputs
The virtual fuses use Infineon power switches. They provide overvoltage, overcurrent, overtemperature and short-circuit protection, as well as reverse-polarity detection. In the app, you set each output’s current limit, up to 15 A. Each bank remains limited to 30 A, and all outputs together to 60 A.

How to read this example setup
The images show real devices and connection illustrations. Currents are example values, not binding specifications of the pictured models. The calculation assumes simultaneous operation in a 12 V system. You can add up to eight 12 V loads in total. Each additional device has its own example current and uses its own free output. If it exceeds the remaining bank capacity, it is shown entirely in an external branch, never split across several outputs. Small auxiliary loads, self-consumption, starting currents and cable losses are not included.
The inverter calculation assumes 90 percent efficiency. The 20 A DC-DC charger connects directly to IN3, rated at a maximum of 25 A. Its charging current is measured internally. The alternative 30 A DC-DC charger exceeds this input and connects externally; a SmartShunt is recommended to include its charging current in the overall measurement. The SmartShunt measures the entire battery current in the common negative return. Switching here demonstrates the principle; actual configuration takes place in the E1NS app.
Explore the connection principles here. You will find the relevant connection details for your build in the installation guide.
