MY-PV Heating Controls

The AC•THOR is a Photovoltaic-Power-Manager for hot-water and space-heating, providing linear control of electric heatsources depending on excess PV power and heat demand. It communicates via Ethernet with inverters, battery systems and smart home controllers and receives information on how much photovoltaic energy is available.

Compatible with the below signal sources for export measurement:

• Carlo Gavazzi (Approved for meter type EM24 with Modbus TCP)
• MY-PV Power Meter
• SMA Sunny Home Manager
• SolarEdge (Sunspec must be enabled on SolarEdge)
• Victron (via Modbus)
• + more

In off-grid systems it can respond to frequency rise to divert surplus energy once the battery is full into heating loads.

Includes:

• 0-3kW linear output.
• 16A relay output.
• Colour touchscreen display

• Warranty: 2 years
• Made in Austria

AC•THOR allows the connection of up to 4 special digital temperature sensors.

Cable length 5 m, diameter 6 mm

The AC•THOR 9s is a Photovoltaic-Power-Manager for hot-water and space-heating for use in 3-phase systems.

Expanding on the features of the standard AC•THOR this 9s version can deliver up to 9kW, has 3 controllable outputs and is suitable for 3-phase immersion heaters (with common neutral conductors) or with three separate 3kW single phase heaters run on separate phases.

Compatible with the below signal sources for export measurement:

• Carlo Gavazzi (Approved for meter type EM24 with Modbus TCP)
• MY-PV Power Meter
• SMA Sunny Home Manager
• SolarEdge (Sunspec must be enabled on SolarEdge)
• Victron (via Modbus)
• + more

In off-grid systems it can respond to frequency rise to divert surplus energy once the battery is full into heating loads.

Includes:

• 0-9kW linear output
• Colour touchscreen display
• Warranty: 2 years
• Made in Austria

The MY-PV Power Meter allows excess solar generation (normally exported to the grid) to be automatically diverted to heaters in order to maximise the self-consumption of your PV system. It detects the energy flows of the PV system and transmits the excess energy data to the PV Power Manager AC•THOR, AC•THOR 9s.

It includes an Ethernet interface for communication with the AC•THOR or AC•THOR 9s via a router or network switch or can be directly connected using a cross-over network cable. Alternatively, connection can be via standard powerline adapters.

Includes 3 x 60A CT clamps (other CT clamps can also be used).

Safety Note: CTs must never be operated open-circuit (secondary coil wires disconnected) once installed, whilst on a current-carrying conductor, as dangerously high voltages may occur under these circumstances.

For direct connection to a dedicated PV system using 4-8 standard 60 cell modules. The DC current from the photovoltaic modules is controlled with a MPP-Tracker for a maximum power output of the immersion heater (up to 2kW). No connection to a grid supply or inverter is required.

• MC4 connectors for connection of PV input.
• Optional boost backup-function can use an AC supply to heat water in the event of bad weather (750W).

Advantages

• Linear power control 0 - 2.000W
• 100 % self-consumption of solar power
• No permission for a grid connection required
• Easy to install, no maintenance costs
• Easier and cheaper than solar-thermal systems
• 2 ELWAs enable stratification charge
• Also works during grid-blackouts
• Hot-Water securing (Boost-Backup) included

For use in off-grid systems to use surplus energy once a battery has become fully charged.

The ELWA-AC-F detects frequency rise of the inverter, if there is excess energy available and uses it for heating water.

Advantages

• AC ELWA-F uses energy that cannot be stored in the battery
• Linear power control 0 - 3.000W for maximum self-consumption
• The AC ELWA-F needs no communication cables to the inverter
• Sinusoidal current consumption (no thyristor)
• For AC off-grid systems with frequency-shift inverters eg. Sunny Island & Victron
