12 V inverter/charger for 230 V systems: compact, high-efficiency Victron MultiPlus combining an 800 VA pure sine wave inverter, a 35 A adaptive charger and a high-speed 16 A AC transfer switch for marine, RV and off-grid use.

• 800 VA 12 V pure sine wave inverter: converts 12 V DC into 230 V AC; approx. 700 W continuous (800 VA), 1600 W peak for motor starts.
• Adaptive 35 A 4-stage smart battery charger (bulk/absorption/float/storage): designed to enable safe and efficient unattended charging of a 12 V battery. Charge currents: house battery 35 A; starter battery 1 A; storage mode voltage 13.2 V. Bulk protection limits bulk charge time to 10 hours. Temperature compensation uses the supplied sensor to adjust charging voltage with temperature.
• Uninterruptible power supply (UPS): high-speed 16 A AC transfer switch provides seamless inverter power if shore or generator supply fails.
• Additional intelligent features: PowerControl (limits AC input current), PowerAssist (supplements AC source capacity), programmable relay (alarm/generator start-stop), parallel and 3-phase capability (up to 6 units in parallel; three-phase systems supported using sets of identical units).
• Protection and safety: protection against over-temperature, short circuit and overload; WeakAC handling to protect the unit when input voltage is heavily distorted; BatterySafe mode to avoid harmful high charge currents where required.
• Storage and bulk protections: Storage mode reduces float charging when the battery has not been discharged for a period; bulk protection limits bulk charging to 10 hours to protect the battery.
• Technical specifications (select): Inverter input voltage range 9.5 - 17 V; output 230 V AC ±2% @ 50 Hz; continuous power approx. 700 W (800 VA); peak power 1600 W; maximum efficiency 92%; zero-load power 7 W. Charger: AC input voltage range 187 - 265 V; charge current house battery 35 A; charge current starter battery 1 A; storage mode 13.2 V. General: transfer switch 16 A; DIP switches for remote/charge voltage/inverter frequency/search mode; internal DC fuse 150 A; operating temperature -40 to +65 °C (fan-assisted cooling); humidity rating up to 95% non-condensing.
• Connectivity: compatible with GX devices (for example Cerbo GX) for remote monitoring and control. Refer to the Victron datasheet for complete environmental and electrical limits before installation.
