Inverter RS Smart 48|6000 — front with LCD display, version without solar input
48 V inverter
Inverter RS Smart 48/6000
Inverter for a 48 V battery bank. It produces a pure 230 V sine wave. You configure it via Bluetooth in VictronConnect. Use the VE.Can port for the GX device. On the AC output you can connect an external grid-synchronised PV inverter and charge the battery; the PV inverter must respond to a rise in frequency by reducing power. For AC coupling, follow the 1:1 rule, the minimum battery requirements and the Victron AC Coupling manual. The manual applies to model PIN482600000.
According to the Inverter RS Smart 48/6000 datasheet and Rev. 07 manual (06/2026). Independent description. Sources
What it is for
230 V from a 48 V battery — no grid and no generator
Inverter RS Smart works with a 48 V battery bank and provides a pure 230 V sine wave: 25 A continuous output current, and at 25 °C from 4600 to 5200 W continuous power according to the manual (the datasheet states 4800–5300 W — design to the lower value).
This is the inverter only: it has no mains charger and no panel input. You charge the battery from an external PV inverter connected to the AC output circuit — AC coupling. The maximum charge power from this source is 5000 W, and the algorithm is the same as in BlueSolar MPPT controllers: bulk, absorption, float.
pure 230 V sine wave, 9 kW peak for 3 s,
charging from a PV inverter on the AC output up to 5000 W (to about 98% SoC),
view and settings on your phone via Bluetooth, monitoring via VE.Can.
Four display lines. The backlit LCD shows battery levels, solar yield and system icons — you will see the same data on your phone.
Off-grid and backup power
Where there is no grid at all
A 48 V battery, a PV inverter on the AC output and one unit that turns it into 230 V. Up to twelve units in parallel or a three-phase system — if the house needs more power.
Features
What Inverter RS Smart can do
Pure 230 V sine wave
25 A continuously, 9 kW for 3 seconds and 7 kW for 4 minutes according to the datasheet. Output voltage adjustable from 210–245 V, frequency 50 or 60 Hz.
AC-coupled PV charging
An external PV inverter on the AC output circuit charges the battery at up to 5000 W. At absorption voltage, current is limited by increasing frequency; the PV inverter stop frequency is 53.2 Hz and cannot be changed.
On-site display
Backlit LCD with four lines: battery levels, solar yield and system icons — no phone and no GX device.
Bluetooth and VictronConnect
Configuration and monitoring via Bluetooth; the default PIN code is on the product label. On Windows you need a VE.Direct to USB interface.
VE.Can to GX device
Monitoring, energy meter, data logging and remote updates. The VE.Direct port is not for GX — you can connect only a GlobalLink 520 to it.
Parallel and three-phase
Up to 12 units, three-phase system from three units, maximum 4 per phase and the same number on each phase. The whole system must work on one battery bank; mixing with Multi RS is not supported.
Battery presets
Normal, High and LiFePO4 2-wire BMS. Absorption is 57.6 V by default, float 55.2 V, charger range 36–60 V — all adjustable.
Earth relay
Enabled by default: connects N to PE when the inverter is running. The enclosure requires earthing (protective class I), and type A residual current protection can be used on the output.

Which model
Inverter RS Smart, Solar version or Multi RS?
This sheet
Inverter RS Smart
A 48 V inverter only. Panels connect to a separate PV inverter on the 230 V side (AC coupling), and charging from this source reaches 5,000 W and about 98% SoC.
without MPPT · without AC charger
With panels directly connected
Inverter RS Smart Solar
The same inverter with a built-in 450 V MPPT charge controller — panels connect directly via MC4 connectors. The current data sheet shows two 3 kW inputs; the manufacturer also describes a version with a single 4 kW tracker. Inverter RS Smart Solar data sheet.
450 V MPPT inside
With mains charger
Multi RS Solar
Also has AC input from the grid or a generator and a charger — the unit switches sources and charges the battery even without sun. Multi RS Solar data sheet.
2 × 450 V MPPT + charger
Solar version. The same enclosure, shown in the manufacturer’s photo with MPPT 450|80 marking — the controller is inside. Details and two MPPT versions: Inverter RS Smart Solar data sheet.
You can see the difference in the base. The Solar version has MC4 connectors for the panel inputs; the model on this data sheet has only the battery and AC connections in this place.
Installation
Connection and installation
High voltage inside
The inside can contain 400–500 V DC even when the unit is switched off. Before working, disconnect all power sources and wait at least 5 minutes. Use insulated tools only. Do not touch uninsulated cable ends.
Mount vertically. Leave 30 cm of free space above and below. Ensure free airflow. Do not cover the ventilation openings.
The surface and surrounding materials must be non-flammable. The enclosure is suitable for wall mounting. Never place the unit directly above lead-acid batteries.
Avoid contact with water. Do not expose the unit to rain or moisture. Protection rating: IP21. Do not install or operate the unit in a wet or dusty environment, where there is a risk of gas or dust explosion, or where the air may contain soot, dust, salt, flammable gases or corrosive vapours.
This is a Class I protective device with a protective earth terminal. You must earth the enclosure. Wider context: earthing and RCD.
You may use a type A residual current device.
Never connect the inverter output to another AC source, such as a mains socket or a generator.
Never connect the battery directly without suitable circuit protection. Every system must have a way to disconnect the AC and DC circuits. If the overcurrent protection is a circuit breaker, it may serve as the disconnect switch; with fuses, separate disconnect switches are required between the source and the fuses.
Make the connections in the order given in the installation section of the manual. First confirm the correct polarity, then connect the battery.
For the battery: flexible stranded copper cable with maximum single conductor diameter 0.4 mm / 0.125 mm² (AWG26) and maximum operating temperature of at least 90 °C. Connection: M8 bolts. Do not remove the lower nut — it is soldered to the PCB. Fit, in order, on the stud: cable lug, flat washer, spring washer and nut; tighten to a maximum of 14 Nm.
230 V AC connection: 10 mm² screw terminals (6 AWG). Torque: 1.2 Nm. The installer must provide strain relief so that stress is not transferred to the terminals. After installation, connections to live parts must be covered.
Use 0.75 mm² wires for voltage measurement.
The temperature sensor is isolated. Attach it to the battery negative terminal.
Minimum battery capacity: 200 Ah (lead-acid) or 50 Ah (lithium), but confirm the battery selection according to the battery manufacturer’s recommendations and with the system designer, especially in terms of total charging current. Batteries must have flammability class HB or better.
All connections in the base. After removing the cover, you can see the battery terminals (M8 bolts), AC connection, control terminal strip and the fans that extract heat through the bottom of the enclosure.

In a parallel system, the AC wiring from the inverters to the common output point must be symmetrical. Connect all units daisy-chained with a VE.Can cable (RJ45 cat5 / cat5e / cat6) with terminators at both ends. In parallel and 3-phase systems, each unit must have individual AC and DC protection; use the same fuse type for each unit.
Settings
Settings
Configuration via Bluetooth in VictronConnect. The default PIN is on the product information label. On Windows, VictronConnect requires a VE.Direct to USB interface.
By default, the unit operates independently, as a single unit.
Built-in battery presets: Normal, High and LiFePO4 2-wire BMS.
Absorption voltage: default 57.6 V. Float voltage: default 55.2 V. Both adjustable. Programmable charger voltage range: 36–60 V.
Inverter output voltage: default 230 V, range 210–245 V. The data sheet mentions frequency adjustment up to 60 Hz; the manual also states adjustment up to 240 V AC and 60 Hz.
Output frequency: default 50 Hz, selectable 50 Hz or 60 Hz.
You can set inverter shutdown as low as 32 V DC, but the unit may still shut down at low AC output voltage (due to load).
The earth relay is enabled by default: it connects N to PE when the inverter is operating.
The default function of the remote terminal is to switch the unit on and off. For the remote terminal to work, the main inverter switch must be in the “on” position.
You enable 2-wire BMS mode in VictronConnect on the battery settings page, in “Remote mode”.
Smart Battery Sense and other VE.Smart Network features are not currently supported. The device is not currently compatible with VE.Smart Networks.
Do not use dynamic cut-off when other loads are connected to the same battery.
Parallel and 3-phase operation
A 3-phase system requires firmware v1.13 or later.
Delta configurations are not supported. Star (Y) with separate neutral is supported.
Continue with missing phase is disabled by default. Do not enable it if you have three-phase loads that require three synchronised phases, for example a three-phase motor; running on two phases may damage the load. If there is a VE.Can problem, units may operate without waveform synchronisation.
Prevent CAN network islanding is enabled by default.
All settings in a parallel or 3-phase system are configured manually, unit by unit. Set up the system mode before connecting loads to the AC output. When you change configuration modes, the AC output is disconnected for a few seconds.
What you can see without a phone. Four lines on the backlit display show current values; all settings are changed over Bluetooth in VictronConnect — the PIN code is on the product sticker.
Display
Display and error codes
The display shows inverter status, power, frequency and AC voltage. The Bluetooth icon changes colour when connected, and flashing means an error or warning. The battery icon fill corresponds to voltage; the icon flashes when the battery is empty.
Protections according to the datasheet
Short circuit on the output, overload, too high or too low battery voltage, too high temperature, 230 V AC on the inverter output, and solar leakage current. In the manual, the table may be marked a–f; the key and the datasheet also include item g.
Error 2
Battery voltage too high
The DC terminal voltage has exceeded the permitted level — the inverter stops operating until it drops.
Clears automaticallyonce the voltage drops.
Error 3, 4
Remote temperature sensor failure
The battery temperature sensor is not responding or is faulty. Check the cable and its mounting on the battery negative terminal.
Error 11
DC ripple voltage too high
Ripple at the battery terminals is too high. This usually means loose connections or DC cables that are too thin.
Error 14
Battery temperature too low
Charging of the LiFePO4 battery is stopped until the temperature returns to the permitted range.
Clears automaticallyafter the battery warms up.
Error 26
Power terminals overheated
The terminals are heating above the permitted temperature. Check the wiring: cable cross-section, tightness and condition of the lugs.
Error 43
Earthing fault
The inverter shuts down when the voltage difference between neutral and protective earth (N–PE) is too large.
Error 50, 52
Inverter overload
Continuous power or peak current on the AC output has been exceeded. Reduce the load and restart the inverter.
Error 51
Inverter temperature too high
The electronics have exceeded the permitted temperature. Provide a cool, ventilated location and clearance around the enclosure.
Clears itselfafter cooling down.
Error 57
AC voltage on output before start-up
There is already AC voltage from another source on the AC output when the inverter is switched on. Check the installation and restart the unit with the power switch.
Does not clear automaticallyrequires a restart.
Notification 65
Communication lost with the other controller
In a parallel system, one of the units has stopped responding. Check the VE.Can wiring and terminators.
Error 67
Connection to BMS lost
The charger is controlled by the BMS, but it is not receiving messages, so it stops charging. Check the connection to the battery BMS.
Error 68
Network is incorrectly configured
The system configuration (parallel or 3-phase) does not match the actual arrangement of units.
Error 71
Different protocol versions on VE.Can
The units have different firmware versions. All of them report error 71 until you update them to the same version.
Error 114
CPU temperature too high
The controller processor has exceeded the permitted temperature.

Diagnostics
Symptom and what to do about it
Overloaded
If the current limit is exceeded continuously, the inverter shuts down for 30 s and restarts automatically. After three such restarts within 30 s of start-up, it remains off — disconnect the load, switch it off and on again.
Low battery voltage
After switching off, the inverter waits at least 30 s and starts when the voltage exceeds the restart threshold. After three cycles within 30 s of start-up, it stops making further attempts — switch it off and on again.
Battery voltage too high
The unit waits 30 s and resumes operation when the voltage drops to the permitted level.
Thermal shutdown
The inverter restarts after 30 s and does not stop trying — unlike overload and low voltage, it does not remain off after several attempts.
Error 57 does not clear
This error does not clear automatically. Check the installation and restart the unit with the power switch.
High DC ripple
Usually loose connections or DC cables that are too thin — check the terminal tightness and cable cross-section.
Battery too small or cables too thin
Efficiency drops, alarms and shutdowns occur, and in extreme cases permanent damage may result.
Ambient temperature too high
This shortens the service life of the device, reduces charging current and peak power, and if the temperature keeps rising, the inverter shuts down.
If the problem persists, contact the dealer or installer from whom you bought the unit. The product has a 5-year limited warranty.
