s DPH

A more powerful version of the domestic 3 kW heater, intended primarily for use in larger buildings for the preparation of hot water (DHW) . The unit is designed to connect a 9 kW heating element (3× 3 kW). The unit can operate independently or as a system of multiple units together with the ANTIK control and communication module, which ensures the functioning of the system as a technological unit together with valve control, water meter reading and circulation pump drive.

Advantages of 9kW photovoltaic water heating:

Clear user interface
Remote water temperature monitoring
Control via app

9 KW Water Heating Inverter

The device contains an MPPT converter that converts the input DC voltage to the output AC voltage with a frequency of 50 Hz. The control unit reads data from the water heating converters, which also provide sensing of water temperatures in the storage tanks and other points on the pipeline. The control unit controls the valves and circulation pumps based on the temperatures, thereby switching the DHW route . At the same time, the consumption of cold water from the water meter is monitored.

Example of connecting 4 units

In case of a requirement to supply a higher thermal output than 9 kW, several 9 kW inverters can cooperate with each other to form one system. In this case, the power of the inverters is added up, which allows to supply the required higher power to the storage tanks.

In this case, the inverters are connected to the Control and Communication Unit, which ensures system supervision from the server, inverter control, servo valve control, water meter reading and circulation pump control based on temperatures at individual points in the system.
