Victron Energy MultiPlus-II Inverter Charger 12/3000/120-50 120V (UL) OPEN BOX SN: HQ22159EKY4

Mounting the MultiPlus-II

• Choose a solid, vertical surface to mount the MultiPlus-II. Ensure the installation space is dry, well-ventilated, and free from dust.
• Secure the unit using the provided mounting holes at the top and bottom of the MultiPlus-II, leaving enough clearance around the unit for airflow.

Connecting the Battery (DC Side)

• Use appropriate DC cables to connect the positive and negative terminals from the battery to the MultiPlus-II.
• Install a fuse in line with the positive cable near the battery to protect against overcurrent.
• If using lithium batteries, connect a Battery Management System (BMS) to manage the charging and discharging processes safely.

Connecting AC Input and Output

• Wire the AC input (shore power or generator) to the designated AC input terminals on the MultiPlus-II.
• Connect the AC output to your distribution board or directly to loads. Make sure to use the correct wire size for the AC side, based on your system’s specifications.
• Follow local wiring regulations, and use strain reliefs to secure the cables.

Grounding the System

• Connect the grounding terminal to the system’s earth point for safety.
• Ensure both the DC and AC sides are properly grounded according to local regulations.
