Victron Quattro‑II 5kVA 24V Inverter Charger

The Victron Quattro‑II 5kVA 24V Inverter Charger is an advanced hybrid power system designed to deliver reliable, high‑quality electricity for homes, commercial sites, off‑grid installations, and backup applications. Manufactured by Victron Energy — a global leader in power electronics — the Quattro‑II series integrates inverter, battery charger, and automatic transfer switch functions into one intelligent powerhouse.

With a rated 5kVA (5000VA) output and a 24V DC battery input, this inverter charger is ideal for medium‑sized solar systems and battery backup solutions. Its pure sine wave output delivers clean, stable AC power that closely matches grid quality. This makes it safe for all types of electrical loads — from LED lighting and entertainment devices to computers, communication equipment, refrigeration units, and small air conditioners — without the noise or electrical stress often caused by modified sine wave alternatives.

What sets the Quattro‑II apart is its multi‑functional energy management capability. It can intelligently balance power from multiple sources: solar arrays, battery banks, the utility grid, and generators. During periods of strong solar generation, the Quattro‑II prioritizes solar energy to power your loads and charge the battery system. When solar input drops — such as at night or during cloudy weather — it seamlessly draws from the battery bank. If the battery charge falls below a set threshold, it will automatically switch to grid or generator power, ensuring uninterrupted electricity supply.

As a fully featured inverter charger, it also includes an adaptive multi‑stage battery charging system. This optimizes charging for battery health and longevity through bulk, absorption, float, and storage phases, and supports a variety of battery types including lead‑acid (AGM, Gel) and lithium‑based chemistries when configured appropriately.

The Quattro‑II 5kVA also features smart transfer switching, allowing simultaneous AC input and output. This means the unit can handle high start‑up loads and power tools or appliances directly even when grid power is present.

Real‑time system monitoring and configuration are facilitated via an intuitive LCD display that shows input/output status, battery levels, load usage, and fault alerts. For advanced integration and monitoring, the inverter supports Victron’s VRM portal, Bluetooth modules, and RS485 communications — enabling remote performance tracking and system control from a smartphone or web browser.

Built‑in safety features include overload protection, short‑circuit protection, over‑temperature shutdown, under/over‑voltage protection, and anti‑islanding safeguards — ensuring both the inverter and connected equipment are protected under varied electrical conditions.

Compact, durable, and easy to install, the Victron Quattro‑II 5kVA 24V Inverter Charger delivers trustworthy performance, unmatched energy management flexibility, and long‑lasting reliability — making it an excellent choice for demanding power applications where efficiency and continuity matter.
