Victron MultiPlus-II 48/3000/35-32 230V

Description

✅ Key Specifications

• Input DC voltage range: 38 – 66 V (48 V nominal battery system).

• Inverter output: 230 VAC ±2%, 50 Hz ±0.1%.

• Continuous output power (at 25 °C): 3000 VA (~2400 W) for this model.

• At higher ambient (40°C) output drops to ~2200 W; at 65 °C about 1700 W.

• Peak (short term) power: ~5500 W.

• larger side: AC input range 187-265 VAC, 45-65 Hz. Battery charge current: 35 A for 48 V version.

• Transfer switch built-in: 32 A.

• Efficiency: up to ~95%.

• ro-load power consumption: very low (e.g., 11 W).

• Communication / expansion: VE.Bus port for parallel or three-phase, remote monitoring capability.

🔍 Key Features & Benefits

• PowerControl & PowerAssist: The unit manages loads intelligently, limiting generator or grid overload by drawing from the battery when needed, and supplementing when grid is weak.

• Seamless UPS function: In event of grid failure, it switches to inverter mode automatically (< 20 ms) so critical loads stay powered.

• Scalable: You can parallel multiple units or configure three-phase systems for larger installations. Good for bigger solar energy storage systems.

• Remote monitoring & system integration: With GX devices (e.g., Cerbo GX) and the VRM portal you can monitor your system and adjust settings remotely. This is useful for service contracts & preventative maintenance.

• Robust design: Broad thermal range (-40°C to +65°C), good for South African climate if installed properly. Powerbox Australia

🛠 Applications & Use-Cases in SA

• For your renewable solar products business: This unit is well suited for a 48 V battery bank system (eg lithium or lead-acid) where you need both inverter + charger functionality in one.

• Off-grid or hybrid grid-tie systems: Use it to feed loads during outages (UPS role), to charge batteries from generator/grid, and to integrate with solar PV.

• Medium sized households or small commercial loads: With ~2400 W continuous output at 25 °C, you can use it for many typical loads (lighting, TVs, small AC units) but large loads like big air-conditioning, heavy motors may exceed continuous rating.

• Service offering: Because of its remote monitoring and scalability you can offer maintenance/monitoring packages to your clients.

⚠️ Important Considerations & Local Installation Tips

• The continuous power rating drops with higher ambient temps: In hot SA installations (especially inside enclosed spaces) ensure adequate ventilation, possibly derate load accordingly.

• Ensure battery bank and wiring are appropriately sized: For 48 V input you’ll need cables, protection, etc per local standards.

• The “transfer switch” of 32 A means when feed-through from grid/generator the maximum is about 32 A. If loads exceed this you’ll rely on battery/inverter side.

• For larger loads (>2400 W continuous) you may need to consider parallel units or higher rating models. Some users in forums report hitting limits:

  “Your loads including vacuum cleaner may consume more than that… thus Multiplus goes in safe mode.” Reddit

• Ensure correct settings for your battery type (lead vs lithium) and application (ESS vs off-grid). The unit supports both, but settings matter.

• Remote monitoring setup: if you want the full benefit, include a GX device and configure VRM monitoring. Good for servicing your clients.

• Local compliance & wiring: Make sure your installation meets South African wiring regulations, earthing, etc.

• Cost & ROI: While this is a quality product, ensure you factor in cost vs benefit for your client.

• Cooling & environment: Keep the unit away from corrosive environments, dust build-up, direct sun. IP22 rating means some protection but still indoor/outdoor sheltered. Victron Energy
