Answer:

EnergyHub Wall 14-28kW

EnergyHub Wall 14kW and EnergyHub Wall 21-28kW are to be placed in a weatherproof space free from condensation. When EnergyHub operates at high power, a speed-controlled fan starts, which may be perceived as disturbing in residential spaces. When placed in a basement, attic, garage, storage room, etc., the noise is not perceived outside the room where EnergyHub is installed.

An EnergyHub Wall 7-14kW generates a heat load of up to approximately 484W at maximum power, so it should be placed where there is some air exchange. If EnergyHub Wall is placed in equipment cabinets or small installation niches, there should be an air exchange with the surroundings of at least 40 l/s. Note that during solar production, the maximum heat load occurs only for a few hours in the middle of the day during the summer, so the average heat load to the building over a day is significantly lower. Therefore, ventilation requirements can be reduced if EnergyHub is placed in large rooms.

Corresponding values for EnergyHub Wall 21-28kW are a heat load of up to 560W and an air exchange with the surroundings of at least 80 l/s for small spaces.

EnergyHub XL Rack Cabinet

EnergyHub XL Rack Cabinet should be placed on a hard, level floor in a weatherproof space free from condensation. Also, consider accessibility for any servicing. See further in the installation manual.

Each EnergyHub XL module in a rack cabinet generates a heat load of up to approximately 560W at maximum power. Therefore, it should be placed in a space with an air exchange of at least 80 l/s per XL module or a room with cooling. Note that during solar production, the maximum heat load occurs only for a few hours in the middle of the day during the summer, so the average heat load to the building over a day is significantly lower. Therefore, if EnergyHub is placed in large rooms, ventilation requirements can be reduced.

For an overview, see the table below.

Exemple:

We have a 24U rack cabinet with 3 EnergyHub XL modules at 28kW each, which are to be installed in a larger apartment building. The apartment building has the electrical room in the basement, so we choose to place the rack cabinet nearby the main electrical panel. We'll have a maximum heat loss of 560W * 3 = 1680W that we need to ventilate away.
