Off-grid charger/inverter Multi HS19 Solar 15k

three-phasefor renewable energyfor solar applications

Overview
The Multi HS19 Solar 15k is a 19-inch rack-mounted 3-phase inverter/charger with integrated solar MPPT tracking, designed for 650–1000 V battery systems. It combines 15 kW continuous 3-phase output, high-voltage battery charging and four independent MPPT inputs in a single rack unit to reduce cabling and simplify installations.

Key features

• High-voltage battery support: compatible with managed CAN-bus battery systems from 650 to 1000 V.
• 3-phase continuous output: 15 kW per unit in one 19-inch rack module.
• Integrated solar tracking: four independent MPPTs, total PV input up to 32 kW.
• High MPPT voltage: up to 600 V per MPPT to enable longer string lengths and reduced parallel wiring.
• Integrated battery charging: supports high-rate charging (example: up to 33 kW at 800 V, depending on configuration).
• High efficiency: inverter efficiency up to 98%; MPPT efficiency ≈99% per tracker.
• Rack-ready design and lightweight (≈26.5 kg) for faster on-site installation.
• Field connectors: touch-safe IP2X Surlok DC connectors, MC4 for PV and push-in AC/other plugs.

Integration & monitoring

• Local configuration and monitoring via Bluetooth with VictronConnect.
• Communications: Battery CAN-bus, VE.Can and GX device compatibility for integration with the Victron ecosystem.
• Remote monitoring and management through the VRM portal; software stack includes VenusOS and support for Node-RED automation.
• Grid-interaction features: PowerControl and PowerAssist for peak shaving and load management.

Applications

• Commercial and residential energy storage systems (ESS)
• Off-grid and hybrid systems
• Backup power and peak shaving solutions
• Large on- or off-grid PV installations requiring compact rack-mounted inverters
• Industrial, telecom, marine and professional vehicle applications when integrated with the Victron ecosystem
