On-grid and off-grid heating direct from solar Increase the size PV installations without DNO approval

SOL-THOR takes power directly from a solar array and transfers it to a heating element, such as an immersion heater or space heater, without the need for a grid connection or external inverters.

Optionally, the SOL•THOR can be connected to a mains supply to allow it to provide heating even when there is insufficient solar power available.

Installing the SOL•THOR does not require DNO approval, so is a cost effective method of increasing the size of a PV installation on sites with limited grid connections.

Technical specifications:

• Parallel connection of up to 2 module strings

• Input current of up to 26A

• Input voltage range: 30 to 230VDC

• Waterproof construction suitable for use in all weather conditions and for outdoor installations

Utilize solar power directly for heat generation.

The SOL•THOR is a 3.6 kW DC power manager for photovoltaic heat. The self-sufficient water heating system
utilizes every watt from the photovoltaic modules directly. The SOL•THOR linearly controls the connected heating
elements from 0 to 3.6 kW to maximize the yield of photovoltaic heat.

Performance

The SOL•THOR can be flexibly used with a PV system ranging from 1 to 10 PV modules. To ensure hot water
supply, the DC power manager can optionally switch to grid power for additional heating. The device efficiently
uses solar power by transferring the direct current from the photovoltaic modules almost loss-free to a connected
heating element and converting it into heat. Additionally, it is possible to alternately control two heating
elements.

Advantages over solar thermal systems

„ Easy installation: only electrical cables, no piping
„ Virtually no losses between PV generator and heat storage
„ Maintenance-free: no moving parts, no antifreeze checks
„ Higher yield from PV modules at lower ambient temperatures
„ No stagnation issues, restarts automatically
