Inverter/caricabatterie Victron Energy MultiPlus-II 3000VA da interno, nero/blu

The Victron Energy MultiPlus-II 3000VA indoor is a combined power inverter and charger designed for indoor installation. It converts DC battery power into AC mains power and charges batteries from AC sources while supporting automatic transfer between grid and battery. With a continuous 3000 VA output and integrated power management functions, the MultiPlus‑II provides regulated AC output and battery charging suitable for backup power, off‑grid systems and mobile installations that require uninterrupted AC supply and controlled battery charging.

Advantages

The MultiPlus‑II integrates inverter and charger functions in a single compact unit for space-efficient indoor use. It delivers uninterrupted switching between shore/grid and battery without interruption to sensitive loads, and includes configurable power assist features that supplement limited AC sources with battery power during peak demand. The unit provides regulated sine-wave AC output, built-in battery charging with adjustable charge profiles, and compatibility with remote monitoring and control systems for convenient system management.

Suitable for

• Home backup systems that require seamless transfer to battery power during outages
• Off-grid solar installations combining battery storage and AC loads
• Mobile or vehicle installations where indoor mounting is possible and reliable AC power is needed
• Small commercial setups requiring continuous AC supply and managed charging

How to use

Install the unit in a dry, ventilated indoor location following local electrical codes and the manufacturer's installation guidelines. Connect the DC battery bank to the inverter/charger using appropriately sized cabling and install a suitable DC isolator or breaker. Connect the AC input to the available AC source and connect the AC output to the distribution or load circuits. Configure charge settings and transfer parameters using the device interface or compatible remote control/monitoring system, and verify operation by testing transfer between AC source and inverter under load.

Recommendations

Use battery and cable sizes recommended for the system's continuous and surge currents, maintain proper ventilation around the unit, and programme charge profiles to match the battery type. Regularly monitor system status via supported interfaces to ensure correct operation and to perform preventive maintenance.
