PV heating
DeltaTherm® PV MAX
Availability expected as of quarter 3/2024
Whether in new or existing buildings, the DeltaTherm® PV MAX
combines Power to Heat and heating control. It detects excess PV current
reliably and calculates the power available. Furthermore, it distributes
the current available in a modulating manner to up to 3 electric immersion
heaters with a total power of 9000 W, controls an SG-ready heat pump and a charging station for electric vehicles as needed. Numerous
optional functions can be activated and heating circuits controlled with
extension modules.
Power-to-Heat controller incl. 3 Pt1000 sensor (3x FRP6)
- Suitable for all grid-connected PV systems
- Maximisation of self-consumption
- Household current priority
- Stepless control of up to 3 electric immersion heaters
- Control of a heat pump
- Control of a wallbox
- Time-controlled backup heating (with mains current)
- Optional functions via extension modules: 5 mixed heating circuits, DHW heating, circulation and thermal disinfection, solid fuel boiler, heat exchange
- 0-10 V control (optional)
- Smart Remote access (optional)
- Access to the VBus.net visualisation portal via LAN
