With proven Victron reliability, flexible configuration options and extensive approvals, it is an ideal choice for homeowners, installers and trade professionals seeking a robust, future‑ready power solution.

Key Features

• All‑in‑one inverter/charger – Combines 48V DC to 230V AC pure sine wave inverter, 70A battery charger and 50A transfer switch in one compact enclosure, simplifying system design and installation.
• ESS‑ready for solar and storage – Integrated Energy Storage System functionality makes it suitable for both off‑grid and grid‑connected PV systems, supporting self‑consumption and backup power strategies.
• PowerControl and PowerAssist – External current sensing (up to 32A typical, with options up to 50–100A depending on system design) allows the unit to limit grid or generator draw and supplement peak loads from the battery when needed.[1]
• High continuous and peak power – Delivers 5000VA / 4000W continuous output (at 25°C) with up to 9000W peak power for starting demanding loads such as pumps, compressors and power tools.
• Advanced battery charging – Adaptive 70A charger with configurable charge profiles and temperature‑compensated charging to optimise battery life and performance for lithium and lead‑acid chemistries.
• Flexible monitoring and control – Supports on‑site configuration via VEConfigure and MK3‑USB, plus remote monitoring and management through GX devices and online portals.
• Scalable system design – VE.Bus connectivity allows parallel and three‑phase configurations, enabling higher power and redundancy in larger residential or commercial systems.
• Robust and installation‑friendly – Steel enclosure with IP22 protection, straightforward wiring access and clear documentation to speed up professional installation and commissioning.
• Global approvals and safety – Built‑in anti‑islanding and compliance with key international standards support use in a wide range of countries and grid environments.

Why Buy
