Outdoor soundproof enclosure made of steel and coated with epoxy powder paint to ensure optimal corrosion resistance. The enclosure is RAL6017 green, while the roof, base, and front panel are RAL7012 gray. It is equipped with sound-absorbing material that provides high acoustic insulation. Access for routine and non-routine maintenance is facilitated by sturdy, lockable access doors. Inside the enclosure is a residential-grade muffler with a noise reduction of 35 dB(A). The central lifting hook is certified. Fresh air intake and hot air exhaust occur vertically through special sound-insulating ducts.
PRODUCT SPECIFICATIONS

ELECTRICAL PANEL
AUTOMATIC
The EY-R300S generator, part of the RENTAL line, features an advanced electrical panel that ensures safe and reliable operation. The ComAp AMF25 control unit is centrally located and protected by a viewing window, which provides optimal visibility. Equipped with an integrated battery charger and a periodic test function, the system allows for constant monitoring and easy connection to the grid.
The sturdy metal structure with IP44 protection is weather-resistant, offering reliability and a long service life. The panel includes a high-capacity terminal block with additional circuit breakers and ground fault circuit interrupters.
Accessories include a USB port and a 230V 16A CEE outlet, ideal for charging the battery or powering the heater. The auxiliary circuits are protected by circuit breakers, while the safety system is complemented by an emergency stop button and a grounding terminal.
The fuel monitoring system uses an electronic float, while an alarm system detects any issues, such as voltage fluctuations, irregular frequency, low oil pressure, high water temperature, alternator failures, or insufficient fuel level. Finally, there are digital gauges for oil pressure and engine temperature.
