AC inverter-charger Multi RS19

DCbattery

Product overview
The Multi RS19 Solar 48/6000/100-450/100 230V is a lightweight, high-frequency 48 V / 6 kVA inverter/charger with two independent 3 kWp PV MPPT trackers (65–450 V DC per tracker). It is the 19" rack variant designed for compact battery-rack installations and is suitable for grid-connected, hybrid and off-grid systems.

Grid-connected functionality
Supports Dynamic ESS for grid-tied energy storage systems and can be paired with AC‑coupled PV inverters. Excess PV can be added via AC‑coupled inverters whose output is managed automatically by the Multi RS frequency-shift power control. The unit also supports direct grid connection without batteries to allow initial installation without storage.

Off-grid functionality
Provides battery charging and inverter support in standalone systems. The device maintains battery state of charge and supplies additional power during peak demand, enabling reliable off-grid operation.

Monitoring & integration
All parameters are available via the integrated display and the VictronConnect app (historical trends supported). For advanced ESS functions (zero-export, backup mode, advanced control) the product can be connected to a GX device (e.g. Cerbo GX).

Performance & design
High-frequency topology delivers high efficiency in a compact, quiet and lightweight enclosure with low standby consumption, making the unit suitable for installations where space and weight are constrained.
