The following requirements must be met:

My delivery address is in Germany.
The installation will only take place if the photovoltaic system is installed on or near my private residence, apartments and public and other buildings that are used for activities serving the common good.
I confirm that the installed gross output of the photovoltaic system is or will be no more than 30 kW (peak) according to the Market Master Data Register (MaStR).

I am the operator of the photovoltaic system. The ordered goods will not be resold commercially.
I confirm that the components ordered are used exclusively to utilize the electricity generated by solar modules for energy management.
I expressly confirm that all the information I have provided is true. I am aware that I am fully liable for any false statements.

*VAT-Free delivery according to Section 12 (3) UStG.
Since January 1, 2023, photovoltaic products have been freed from VAT based on a funding measure. As a result, private individuals receive significant tax relief when buying solar products to promote solar energy.

The following requirements must be met:

Opendtu / Ahoydtu Diy Kit

This DIY KIT is suitable for reading the data of a hymile inverter.

Communication with the Hymiles interverters takes place via 2.4GHz via radio. It is possible to access current values such as power, electricity, daily energy. Setting parameters such as the performance limit via web interface or MQTT.

The following Hymiles Referees are currently supported by Opendtu with the NRF24L01+ radio module: HM-300-1T, HM-350-1T, HM-400-1T, HM-600-2T, HM-700-2T, HM-800-2T, HM-1000-4T, HM-1200-4T, HM-1500-4T

Further inverter supported by Opendtu: Solenso SOL-H350, Solenso SOL-H400, Solenso SOL-H800, TSUN TSOL-M350*, TSUN TSOL-M800*, TSUN TSOL-M1600*, E-Star HERF-800, E-Star HERF-1600, E-Star HERF-1800

*Note on TSUN compatibility: The compatibility with Opendtu is most likely related to the serial number of the inverter. Current findings indicate that TSUN inverters are supported with a serial number that begins with "11", while inverter is not supported with a serial number that begins with "10".

The optionally contained OLED Dispaly impresses with a high quality of representation. With the size of approx. 2.44cm, it has a resolution of 128 x 64 pixels. This shows texts and graphics with a high level of detail and sharpness.

With the I2C connection you can easily integrate the display into your DIY projects. Completely compatible with Arduino, 51 series, MSP430 series, STM32/2, CSR IC, etc.
