2.3 Inverter room design
The inverter room comprises the following components:
2x inverter (WxHxD = 2700mm x 2100 mm x 700 mm / 1965 kg)
1x AC cabinet (WxHxD = 600 mm x 2000 mm x 600 mm / approx. 400 kg) Equipment:
• Socket outlets on the door • Light switch on the door • Lighting Luminaires 2 x 2 x 58 W • Smoke detector (optional) • Thermostatically controlled heater for frost protection 2 kW, 230 V (optional) • Container temperature sensor • Warning notice: "In order to ensure a safe escape route, do not open the doors of more than one inverter at a
time!“
Door: • Width/height, e.g. 1100 mm/2400 mm clearance dimension (door size suitably dimensioned to allow future
replacement of a complete inverter subunit) • Single-leaf aluminum door • Locking system (with panic lock with knob on outside, latchkey on inside) • Doors must open outwards
Openings in floor: • 1 x 300x300 mm below the AC cabinet • 4 x 600x180 mm below the inverters
The inverter room dimensions are specified below:
Length (internal): 3900 mm
Width (internal): 2800 mm
Height (internal): 2600 mm
Minimum aisle width: 1240 mm

2.4 Transformer room design
The MV transformer room must be designed to accommodate an oil-immersed or a cast-resin transformer. • 1000 kVA transformer (with casters) • Dimensions (approx.): Length: 1,800 mm
Width: 990 mm Height: 2,180 mm
• Total weight: Approx. 4,000 kg
Equipment: • Light switch on the door • Lighting Luminaires 1 x 2 x 58 W • Transformer rails with side track limits • Removable red warning strip directly behind the door to protect personnel • Doors must open outwards • Fire protection, water pollution control measures, etc. for oil-immersed transformers (oil drip tray, e.g. made
of sheet steel, with oil-tight welds)
Door: • Width/height, e.g. 1100 mm/2400 mm clearance dimension (door size suitably dimensioned to allow future
replacement of an MV transformer) • Single-leaf aluminum door • Locking system (with panic lock with knob on outside, latchkey on inside) • With ventilation elements
Openings in floor: • 2 x 500x300 mm
The load assumptions for the cable support racks must be taken into account and suitable cable fasteners must be provided.
The minimum transformer room dimensions are specified below:
Length (internal): 2370 mm
Width (internal): 1540 mm
Height (internal): The room should be at least 50 cm higher than the maximum height of the transformer.

2.5 Switchgear room design (optional)
Installation of MV switchgear is optional. The container is capable of accommodating air-insulated or SF6-insulated switchgear, e.g. Siemens 8DJH, 2-4 panels, height 1400mm.
Equipment: • Socket outlets on the door • Light switch on the door • Lighting Luminaires 1 x 2 x 58 W • Pressure-relief openings with appropriate air ducts, expanded metal grids, etc. must be provided.
The dimensions of the necessary pressure-relief openings depend on the type of switchgear and the short-circuit current.
Door: • Width/height, e.g. 1110 mm/2400 mm clearance dimension (door size suitably dimensioned to allow future
replacement of switchgear) • Locking system (with panic lock)
Drilling patterns for MV switchgear (specific to project)
Length (internal): specific to project
Width (internal): specific to project
Height (internal): 2600 mm

2.7 Ventilation (air supply and extraction)
The air supply and air extraction systems of the inverter room and transformer room are mutually decoupled.
Inverter room:
Air enters the room through a supply air opening in the container side wall.
The air requirement of the inverter room is approximately 13,000 m³/h.
Without air-filter:
2 centrifugal fans (K3G 355-AX56 -02, supplied by ebmpapst) are required. • Supply air opening with supply air fan and external louvers • Fan control in the AC cabinet • Outlet-air openings above the INV cabinets on side walls (opening 4 x 488 mm x 1255 mm) • Exhaust air from the PV INV is transported through fan shrouds to outlet-air openings • Fan shrouds and sealing material are available as accessories • External louvers for outlet-air openings • Order kit: Fan shroud for PVS500 (shrouds, fastening elements and sealing material)
With air-filter:
4 centrifugal fans (K3G 355-AX56 -02, supplied by ebmpapst) are required. • Supply air opening with external air filter with integrated fan • Fan control in the AC cabinet • Outlet-air openings above the INV cabinets on side walls (opening 4 x 488 mm x 1255 mm) • Exhaust air from the PV INV is transported through fan shrouds to outlet-air openings • Fan shrouds and sealing material are available as accessories • External louvers for outlet-air openings • Order kit: Fan shroud for PVS500 (shrouds, fastening elements and sealing material)
