Product Description The Victron Energy MultiPlus-II 48/4k5/55-32 is a robust inverter/charger designed for 48 V battery systems that need reliable AC power and smart battery management in one tidy unit. It delivers clean 230 V AC via a pure sine wave inverter, alongside an intelligent multi-stage charger that supports long-term battery health. When an AC supply is available, it can power your loads and charge your batteries at the same time. If your grid, generator or shore supply is limited, PowerControl helps you stay within safe current limits, and PowerAssist can cover short peaks by drawing additional energy from the battery. This reduces nuisance trips and helps keep the system stable under changing loads. With two AC outputs, you can keep essential loads protected while ensuring non-essential loads only run when AC input is present – a simple way to control battery usage in real-world installs. This model is a strong fit for larger off-grid systems, backup installs and ESS setups that need dependable performance and sensible control. Key Features Combined inverter and charger – One unit provides pure sine wave AC power and intelligent multi-stage battery charging. ESS-ready functionality – Designed for energy storage systems, with support for external current sensing to optimise self-consumption. Pure sine wave output – Clean, mains-quality 230 V AC suitable for sensitive electronics and everyday appliances. PowerAssist – Supports peak loads by supplementing limited grid, generator or shore power with battery power when needed. PowerControl – Helps prevent overloading your AC source by limiting incoming current and managing charging accordingly. Two AC outputs – Main output stays live during a mains failure, plus a second output that is only live when AC input is available (handy for non-essential loads).
