Protocol inverter-charger Multi HS19

databatteryBluetooth

Overview
Designed for 650–1000 V battery systems, the Multi HS19 Solar 15k integrates 3-phase inverter/charger functionality and four MPPT solar trackers into a single 19-inch rack unit. High-voltage architecture reduces currents, cable cross-sections and losses for compact, efficient rack installations within the Victron ecosystem.

Key features

• Support for high-voltage battery banks (650–1000 V).
• Full 3-phase output in a 19-inch rack form factor; 15 kW continuous inverter/charger.
• Four independent MPPT trackers, combined PV input up to 32 kW; MPPT input voltage up to 600 V.
• High inverter efficiency (up to 98%) and MPPT tracker efficiency (~99%).
• Lightweight rack design (26.5 kg) for simplified handling and one-person installation.
• PowerControl and PowerAssist to manage grid limits and supplement grid power with battery energy.

Applications

• Utility-connected and commercial/residential ESS (energy storage systems) and peak shaving.
• Rack-mounted installations requiring compact three-phase power.
• Off-grid, backup and critical-load systems with high-voltage batteries.
• Arrays with shading or mixed orientations where multiple MPPTs improve yield.

Integration & monitoring

• Local configuration via Bluetooth and VictronConnect.
• Connect GX communication centres (VenusOS) for remote monitoring on VRM and full system integration.
• VE.Can / Battery CAN-bus support for compatible battery communication and system control.
• Node-RED support (VenusOS) and third-party integrations for advanced automation.

Installation & connections

• Rack-ready 19-inch form factor for organised, compact installations.
• Touch-safe IP2X Surlok connectors for DC battery connections.
• MC4 solar connectors and push-in plugs for AC to simplify wiring and reduce onsite labour.
• High-voltage layout reduces cable sizes and installation cost on long runs.
