1. SAFETY INSTRUCTIONS EN In general Appendix Please read the documentation supplied with this product first, so that you are familiar with the safety signs en directions before using the product. This product is designed and tested in accordance with international standards. The equipment should be used for the designated application only. WARNING: DANGER OF ELECTRICAL SHOCK The product is used in combination with a permanent energy source (battery).
2. DESCRIPTION 2.1 In general The basis of the MultiPlus is an extremely powerful sine inverter, battery charger and automatic switch in a compact casing. The MultiPlus features the following additional, often unique characteristics: Automatic and uninterruptible switching In the event of a supply failure or when the generating set is switched off, the MultiPlus will switch over to inverter operation and take over the supply of the connected devices.
2.2 Battery charger EN Adaptive 4-stage charging characteristics: bulk – absorption – float – storage The microprocessor-driven adaptive battery management system can be adjusted for various types of batteries. The adaptive function automatically adapts the charging process to battery use. Appendix The right amount of charge: variable absorption time In the event of slight battery discharge, absorption is kept short to prevent overcharging and excessive gas formation.
3. OPERATION 3.1 On/Off/Charger Only Switch When switched to "on", the product is fully functional. The inverter will come into operation and the LED "inverter on" will light up. An AC voltage connected to the "AC in" terminal will be switched through to the "AC out" terminal, if within specifications. The inverter will switch off, the "mains on" LED will light up and the charger commences charging. The "bulk", "absorption" or "float" LEDs will light up, depending on the charger mode.

4. Installation This product may only be installed by a qualified electrical engineer. 4.1 Location The product must be installed in a dry and well-ventilated area, as close as possible to the batteries. There should be a clear space of at least 10cm around the appliance for cooling. Excessively high ambient temperature will result in the following: • Reduced service life. • Reduced charging current. • Reduced peak capacity, or shutdown of the inverter.
4.3 Connection of the AC cabling EN Appendix The MultiPlus is a safety class I product (supplied with a ground terminal for safety purposes). Its AC input and/or output terminals and/or grounding point on the outside of the product must be provided with an uninterruptible grounding point for safety purposes. The MultiPlus is provided with a ground relay (relay H, see appendix B) that automatically connects the Neutral output to the chassis if no external AC supply is available.
4.4 Optional Connections A number of optional connections are possible: 4.4.1 Second Battery The MultiPlus has a connection for charging a starter battery. For connection see Appendix A. 4.4.2 Voltage Sense For compensating possible cable losses during charging, two sense wires can be connected with which the voltage directly on the battery or on the positive and negative distribution points can be measured. Use wire with a cross-section of 0,75mm².
5. Configuration EN • • • Settings may only be changed by a qualified electrical engineer. Read the instructions thoroughly before implementing changes. During setting of the charger, the AC input must be removed. Appendix 5.1 Standard settings: ready for use On delivery, the MultiPlus is set to standard factory values. In general, these settings are suitable for single-unit operation.
Inverter voltage Output voltage of the MultiPlus in battery operation. Adjustability: 95 – 128V Stand-alone / parallel operation / 2-3 phase setting Using several devices, it is possible to: • increase total inverter power (several devices in parallel) • create a split-phase system by stacking (only for MultiPlus units with 120V output voltage) • create a split-phase system with a separate autotransformer: see VE autotransformer datasheet and manual • create a 3-phase system.
EN AC input current limit These are the current limit settings for which PowerControl and PowerAssist come into operation. PowerAssit setting range: From 5,3A to 50A for models with 50A transfer capacity Factory setting: the maximum value (50A). See Section 2, the book 'Energy Unlimited', or the many descriptions of this unique feature on our website www.victronenergy.com.
5.3 Configuration by computer All settings can be changed by means of a computer or with a VE.Net panel (except for the multifunctional relay and the VirtualSwitch when using VE.Net). The most common settings (including parallel and 3-phase operation) can be changed by means of DIP switches (see Section 5.5). For changing settings with the computer, the following is required: - VEConfigure3 software: can be downloaded free of charge at www.victronenergy.com. - A MK3-USB (VE.
5.5 Configuration with DIP switches EN A number of settings can be changed using DIP switches (see appendix A, position M). General procedure: Appendix Turn the Multi on, preferably without load and without AC voltage on the input. The Multi will then operate in inverter mode. Step 1: Setting the DIP switches for: - the required current limitation of the AC input. - AES (Automatic Economy Switch) - limitation of the charging current. - selection of stand-alone, parallel or 3-phase operation.
5.5.1.3 Battery charge current limitation (default setting 75%) For maximum battery life, a charge current of 10% to 20% of the capacity in Ah should be applied. Example: optimal charge current of a 24V/500Ah battery bank: 50A to 100A. The temperature sensor supplied automatically adjusts the charge voltage to the battery temperature.

6. Maintenance The MultiPlus does not require specific maintenance. It will suffice to check all connections once a year. Avoid moisture and oil/soot/vapours, and keep the device clean. 7. Error indications With the procedures below, most errors can be quickly identified. If an error cannot be resolved, please refer to your Victron Energy supplier. 7.1 General error indications Problem Cause No output voltage on AC-out-2. Multi will not switch over to generator or mains operation.
Circuit breaker or fuse in the AC-in input is open as a result of overload. The battery fuse has blown. The charger does not operate. “Bulk” LED flashes and “Mains on” LED illuminates. The distortion or the AC input voltage is too large (generally generator supply). MultiPlus is in “Bulk protection” mode thus, the maximum bulk charging time of 10 hours is exceeded. Such a long charging time could indicate a system error (e.g. a battery cell short-circuit).
7.2 Special LED indications (for the normal LED indications, see section 3.4) Bulk and absorption LEDs flash synchronously (simultaneously). Absorption and float LEDs flash synchronously (simultaneously). "Mains on" flashes and there is no output voltage. Voltage sense error. The voltage measured at the voltage sense connection deviates too much (more than 7V) from the voltage on the positive and negative connection of the device. There is probably a connection error.
EN All of the conditions below must be met!: The device is in error!
