Professional 12 V inverter/charger delivering 2000 VA output with an 80 A charger and a high-speed 32 A AC transfer switch for marine, mobile and off-grid systems.

• Key functions: 1. 2000 VA 12 V pure sine wave inverter: converts DC current into 230 VAC mains to run TVs, laptops, lighting and motorised appliances; 2000 VA continuous output with 3500W peak.
• Adaptive 80 A 4-stage smart battery charger (bulk - absorption - float - storage): designed for safe and efficient unattended charging of a 12 V battery with adaptive charge technology.
• Uninterruptible power supply (UPS): this inverter/charger features a high-speed 32 A AC transfer switch for seamless transfer between shore/generator and inverter power.
• Additional intelligent features: As well as the 3 key functions, the MultiPlus offers several additional features including PowerControl to set maximum AC input current and PowerAssist to supplement the AC source during peak loads.
• Programmable relay and remote monitoring: programmable relay for custom alarms/controls; pair with a GX device (e.g. Cerbo GX) for remote monitoring and control across multiple operating systems.
• Parallel and 3-phase operation capability: can be paralleled with other identical MultiPlus units and configured for three-phase installations where required.
• Inbuilt safety protection: comprehensive protection against output short circuit, overload, overheating and other potential hazards to keep systems and appliances safe.
• Modes and safeguards: Weak AC detection (severe input distortion can limit charger operation); BatterySafe mode to reduce battery stress during high-current charging; Storage mode reduces float voltage when battery is unused; Bulk protection limits bulk charging to 10 hours when enabled; temperature compensation via supplied sensor adjusts charge voltage for ambient conditions.
• Electrical specifications: Inverter input voltage range 9.5–17 V; output 230 VAC ±2% @ 50 Hz; peak power 3500 W; maximum efficiency 93%; zero-load power 10 W. Charger AC input range 187–265 VAC. Charge voltages: absorption 14.4 V, float 13.8 V, storage 13.2 V. Charge current (house battery) 80 A; starter battery 1 A. Transfer switch: 32 A. Dip switches: yes (battery charge voltage/search mode).

Suitable for boats, motorhomes and off-grid installations; install with correct DC cabling, fusing and a qualified electrician or marine electrician. For full system control and remote telemetry pair with a Cerbo GX or compatible GX device.
