Summary of "☀️#Victron #Multi RS6000 Solar - First View - Teil 1☀️"
Tech-focused summary (Victron Multi RS6000 Solar – “First view”, Teil 1)
What the device is
- The Victron Multi RS6000 Solar is described as a high-frequency MultiPlus with an integrated RS450.
- It includes two MPPT solar inputs, intended for two solar arrays / two strings.
- Compared with a typical MultiPlus 2:
- It is positioned as lighter and more compact
- It is rated as more powerful (stated 6000 VA vs 5000 VA)
- Claimed weight: ~11 kg (contrasted with much heavier MultiPlus units)
Major technological change
- Earlier MultiPlus designs used a large toroidal transformer; this model removes that component.
- The 48 V ↔ 230 V conversion is performed using switching / switched-mode power supply technology.
- The presenter emphasizes that this is a fundamentally different architecture and suggests possible implications such as different EMC/EMI behavior (not yet measured—described as a suspicion).
Control / connectivity expectations
- The presenter expects the need for external control hardware (e.g., servo / GX device / Raspberry Pi) because the unit is not self-contained with integrated control.
- Standalone operation may still be possible, similar to older MultiPlus behavior.
- The expected display should show solar power, similar to RS450 behavior (with more detail promised later).
- Connectivity shift noted:
- VE.Direct + CAN are mentioned
- The presenter indicates it’s not VE.Bus, implying Victron is moving more toward CAN / VE.Direct.
Install-oriented hardware inspection notes
- Improved on-board wiring/terminal layout:
- Angled screws for opening the case are designed so you don’t need to access from below with a screwdriver (installer convenience improvement).
- The connection area is compared conceptually to MultiPlus units:
- There are minor ordering differences for AC terminal blocks (e.g., AC1/AC2 placement).
New/changed protection and switching features
- The unit still includes NA protection between AC input/output.
- ACA 2 behavior differs from the presenter’s expectation based on typical MultiPlus designs (notably: ACA 2 failing on AC neutral outage).
- A DC load disconnect switch is added—described as something that did not exist in older MultiPlus designs.
- Integrated surge protection is found on internal board(s), suggesting fewer external surge protection accessories may be needed.
- Integrated DC fuses are present.
- A surge protection board appears removable/replacable via screws, making it more service-friendly.
Internal architecture (component-level teardown observations)
Internals are described as split into functional blocks:
- DC-DC converter stage (back section)
- An integrated RS450 / RS6000 portion responsible for MPPT and power processing
- A mains output section with relays for neutral/phase isolation (NA protection) and other switching
- A control board including an ESP reference
Additional observations:
- Large smoothing capacitors: described as 500 V, about ~550 µF
- Cooling:
- Uses two PC-style fans
- Reported as not particularly loud compared with MultiPlus fans
Repairability / modularity
- Multiple boards appear connector-based, implying they can be replaced without extreme disassembly.
- The NA protection module is described as screw-mounted with connectors.
- Overall: described as repair-friendly, though any failure at the mainboard level would still likely require significant teardown.
First functional test results (efficiency not finalized)
- Test prerequisites include connecting to a battery and ensuring power-up via BMS on/unlocked.
Immediate inverter output test
- After power-on, output 1 produces 230 V immediately.
- Output 2 correctly shows no output for this test setup (as expected).
Idle power draw
- Measured roughly 0.5 A at ~52 V → about ~26 W consumption.
- Compared to a MultiPlus 2 5000 with RS450, described as ~20 W, so “roughly similar” considering the increased RS450 integration.
PV startup / black-start-like behavior
- Test method:
- A 60 V supply plus a DC-DC step-up converter simulates PV voltage higher requirements.
- Result:
- The unit can start and deliver output from PV without a connected battery, indicating possible black start / self-start via PV.
- Notes during startup:
- Relay switching/clicks occur
- Fan whine from the DC-DC converter and/or internal switching activity is noted
Switching to solar operation (battery connected)
- MPPT begins feeding the battery once the battery is connected.
- Reported figures:
- PV/battery-side input around ~254 W
- Output to battery side around ~187 W (losses present)
- The presenter notes the MPPT may not be operating in its most optimal range due to test constraints, so results are not considered “pretty.”
- A lost-state alarm occurred during the test, though the inverter still worked and recovered.
Efficiency testing deferred
- Proper efficiency/load characterization is explicitly deferred to the next video.
- Current setup is described as insufficient power / makeshift, because the test converter couldn’t fully load the unit.
Main speakers / sources
- Main speaker/source: The YouTube channel host, “My Energy Transition” (the presenter who performs the teardown and measurements).
