Blugy 3000W 12V Pure Sine Wave Inverter with BY-PASS (Priority Relay) for caravans, motorhomes and campers.

OPERATION

Bypass function (AC priority relay): by default, when the AC input is within range, the load is powered by the bypass.

Location and ventilation: Install in a dry, clean, and well-ventilated area; maintain at least 30 cm of clearance on each side. Do not obstruct vents or mount in unventilated compartments.

Operating range ambient temperature: -10 °C to 40 °C.

Electrical hazards: check the integrity of the wiring and the appropriate cross-section; do not operate with damaged conductors, or with an inadequate cross-section.

Disconnect AC and DC inputs before maintenance; the front switch does not guarantee absence of internal voltage due to capacitor charging.

Hazardous atmospheres: the equipment may generate areas and sparks during operation; do not install in spaces with fuels, flammable vapors or where ignition protection equipment is required.

Critical connections: Never connect the inverter's AC output to the grid, generators, or its own AC input; this operation will permanently damage the equipment.

  • B Fans
  • C Schuko connector
  • D Barnes of connection
  • F Ventilation grille
  • H Control Panel
• Front ON/OFF switch: enables/disables the inverter.
• LCD screen:
  • Battery capacity: 5 levels (20/40/60/80/100%).
  • Load: 20-100% bars and numerical power reading.
  • AC Out: indicates actual power supplied to the load.
  • AC In and Bypass: show voltage/current when the mains supply is bypassed.
  • LCD fault codes: "Lo" (overload), "Ho" (overtemperature), "U" high (DC overvoltage), "U" low (DC undervoltage).
• Remote control via positive serial number:
  • REMOTE Port: Activation via serial +.
  • The unit will operate as long as a +12Vdc signal reaches the remote terminal, and will turn off when this signal disappears.
  • The remote serial number does not affect the bypass operation; it will activate regardless of the inverter's status. If the unit was off, when the network connection disappears, the inverter will remain in standby mode.
• Preparation: Place the equipment on a firm, dry, and ventilated surface; check the minimum DC section and length to limit voltage drop; retighten after the first ground cycle.
• Sequence:

1. Connect DC(+) and (-) respecting polarity; the recommended tightening torque is 7.85nM
2. Connect the AC input to the rear terminal block.
3. Connect the system ground to the inverter's ground terminal.
4. Switch ON; the green LED will be active; if there is mains power, it will be powered by bypass.
5. Connect the loads to the front Schuko socket or the AC output terminal block; ensure a firm connection to avoid overheating of the connector.

1-USB port, when present, delivers 5V/2.1A for auxiliary power.
