Victron Multi HS19 Solar 15 kW System Combination

The Multi HS19 unit from Victron Energy (MPN: PMR803150300) has a rated power of 15 kW and was designed for 650–1000 V systems. It combines 3-phase power, battery charging, and solar tracking in a compact 19-inch rack unit. High-voltage operation minimizes current levels, cabling requirements, and energy losses, enabling streamlined systems, quick installation, and maximum efficiency within the Victron ecosystem. Four independent MPPT trackers, each with a capacity of up to 8 kW, allow for flexible alignment of four separate groups of solar panels, thereby making optimal use of the available roof space. The Multi HS19 Solar 15k is perfectly suited for off-grid systems, backup solutions, peak shaving, and grid-tied applications.

Your Project—Your Benefits

Quick and easy installation— The Multi is simply installed in a standard 19-inch rack along with the batteries. The entire system is housed in a single enclosure. Fewer components and cables keep things tidy and save time during installation
Reduce cabling costs, increase efficiency— Higher battery voltages allow for the use of thinner, more cost-effective cables, which reduces installation costs. It supports CAN-bus batteries ranging from 650 to 1000 V and enables a charging power of up to 33 kW at 800 V
Optimize grid connection usage— PowerControl prevents overloads by giving priority to connected devices in terms of power consumption. In the event of a short-term increase in demand, PowerAssist automatically supplements power from the battery. This ensures that sufficient energy is always available
Everything at a Glance On-Site — The integrated display provides a clear overview of all operating data. The unit can be easily configured on-site via Bluetooth and the VictronConnect app. A remote on/off connection and a programmable relay enable flexible automation of various processes
A GX unit opens up numerous possibilities— via the VE.Can connection, you can connect a GX communication hub to receive real-time system data, enable remote monitoring via the VRM portal, and centrally control all Victron devices. Functions can be customized, and third-party devices can be easily integrated

High-efficiency 3-phase power

This device combination features state-of-the-art high-voltage and high-frequency technology, achieving an inverter efficiency of up to 98%. This reduces standby power consumption and allows you to benefit from more usable energy from every kilowatt-hour generated. The device operates exceptionally quietly, offers a true 3-phase output, and is pleasantly lightweight at just 26.5 kg.

Higher yield, regardless of the solar modules’ orientation

Four independent trackers enable flexible planning, even in the event of shading or varying module orientations. Each tracker operates at 99% efficiency. The maximum input voltage of 600 V allows for longer cable runs, less parallel wiring, and quick installation.

Applications

Energy storage— The Multi enables effective peak shaving and ensures that large residential and commercial installations make the best possible use of their solar energy. With Victron software, you can easily control when power is stored, consumed, or fed into the grid
Off-Grid Operation - Fewer components, clear system layouts, and the reliability of decades of Victron development. The HS19 Solar is ideal for demanding off-grid applications and offers an optional generator input
Backup – In the event of a power outage, it ensures your system continues to run. High-voltage battery banks secure the power supply for large systems and ensure that critical loads are reliably powered even during extended outages

View and control all your devices and projects

Everything under control, anytime, anywhere— monitor battery status, solar yield, electricity rates, and other key metrics in real time. Adjust settings, start generators, set alarms, or even control devices conveniently via your smartwatch. With Victron system management software, you can flexibly control your system via Bluetooth using the VictronConnect app, or locally and remotely with VenusOS, the VRM portal, and the VRM Watch app
Support without an on-site visit— Through the Victron Remote Management Portal (VRM), installers have remote access to all installed Victron systems at any time. Issues can be detected early, firmware versions checked, analyses performed, and settings adjusted. If an on-site visit is necessary after all, all system data is available so the work can be completed quickly and efficiently
Connect everything, control everything— Victron software is open and compatible with devices from other manufacturers. With a GX communication hub and VenusOS, you can directly control SG-Ready heat pumps, Shelly devices, EV charging stations, and digitally integrated generators. Thanks to the integrated Node-RED in VenusOS, you have numerous automation options at your disposal
Automation at every level— Thanks to the integration of Node-RED, Victron software automatically balances energy supply and demand with daily routines. This keeps your system efficient and reliable. Intelligent control rules prioritize loads, divert excess solar energy to heat storage, automate processes, and flexibly adjust grid consumption based on load
