Discover the Victron Multiplus 800VA 12V Inverter/Charger – your all-in-one power solution for reliable energy wherever you go. This smart device blends a powerful 800VA inverter with a 35A adaptive charger and a high-speed transfer switch into one compact unit. It’s perfect for ensuring uninterrupted power in your caravan, boat, or any off-grid setup. Enjoy consistent, clean power that keeps your sensitive electronics safe and your batteries well-managed, simplifying your entire electrical system.
This advanced unit is designed to provide stable and efficient power, acting as three essential devices in one.
Key Product Features:
- 800VA 12V Pure Sine Wave Inverter: Converts your 12V DC battery power into crisp 230VAC mains electricity. This lets you run common household items like TVs, laptops, and fans. It delivers up to 700W of continuous power and handles strong peak loads of 1600W, great for starting appliances with electric motors. Its pure sine wave output is superior to modified sine wave types, offering higher efficiency and better compatibility with all your devices.
- Adaptive 35A 4-Stage Smart Battery Charger: Safely and efficiently charges your 12V battery without needing constant attention. Its smart system adjusts the charging process for different battery types, always adapting to how you use your battery. This ensures a longer lifespan for your battery.
- Uninterruptible Power Supply (UPS) with 16A AC Transfer Switch: Experience seamless power transitions. If grid power fails or your shore/generator power disconnects, the MultiPlus instantly switches to inverter mode. This happens in less than 20 milliseconds, so sensitive devices like computers won't even notice, preventing data loss or interruptions.
Intelligent Power Management & Protection:
Beyond its core functions, the MultiPlus includes several smart features for enhanced performance and customisation:
- PowerControl: Set a maximum AC input current for your system. The MultiPlus prioritises power for your appliances, using any leftover current to charge batteries. This prevents overloading your generator or shore supply and tripping circuit breakers. (Requires the Multi Control Panel, sold separately.)
- PowerAssist: Boosts your AC power source capacity. If your appliances need more power than available from the AC source, the MultiPlus adds extra current from your battery. Once demand drops, the spare AC power recharges your battery. This allows you to use smaller generators or get more from limited shore power.
- Programmable Relay: A versatile relay that can be set for various tasks, such as sending a start/stop signal to a generator. By default, it acts as an alarm relay, deactivating if there's a pre-alarm (e.g., inverter too hot, low battery voltage).
- Parallel and 3-Phase Operation: Expand your power by connecting up to six identical MultiPlus units in parallel for higher output. Three-phase operation (Y configuration) is also possible. (Requires a standard RJ45 UTP cable, sold separately.)
- Comprehensive Safety Protection: Built-in safeguards protect against output short circuits, overloads, battery overvoltage & undervoltage, overheating, accidental 230 VAC on the inverter output, and excessive input voltage ripple.
- WeakAC Mode: Even with highly distorted input voltage, this setting allows the charger to operate, though it may cause more input current distortion.
- BatterySafe Mode: Prevents battery damage from excessive gassing when fast charging by automatically limiting the voltage increase once the gassing point is reached.
- Storage Mode: Activates after 24 hours of no discharge, reducing float voltage to minimise gassing and corrosion. Once a week, voltage rises to absorption level to 'equalise' the battery, preventing common causes of early battery failure.
- Bulk Protection: Limits bulk charging time to 10 hours. This can alert you to potential system errors like a short-circuited battery cell.
- Temperature Compensation: The included temperature sensor adjusts charging voltage based on battery temperature, crucial for maintenance-free batteries to prevent overcharging and drying out.
Remote Monitoring and Control:
Pair your MultiPlus with a Victron GX device (like the Cerbo GX) for full control and monitoring. Access your system locally via LAN/Wi-Fi or remotely from anywhere in the world using the free VRM app or website. Control is available from your phone, tablet, laptop, or PC across various operating systems.
