☀️#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.
