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.
EN Autonomous operation when the grid fails Houses or buildings with solar panels or a combined micro-scale heating and power plant or other sustainable energy sources have a potential autonomous energy supply which can be used for powering essential equipment (central heating pumps, refrigerators, deep freeze units, Internet connections, etc.) during a power failure. A problem is however that grid connected sustainable energy sources drop out as soon as the grid fails.
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 6,3A to 50A. Factory setting: the maximum value (50A). See Section 2, the book 'Energy Unlimited', or the many descriptions of the unique PowerAssist feature on our website www.victronenergy.com. Appendix AC input current limit These are the current limit settings for which PowerControl and PowerAssist come into operation.
5.3 Configuration by computer All settings can be changed by means of a computer or with a VE.Net panel (except for the multi-functional relay and the VirtualSwitch when using VE.Net). The most common settings can be changed by means of DIP switches (see Section 5.5). NOTE: This manual is intended for products with firmware xxxx400 or higher (with x any number) The firmware number can be found on the microprocessor, after removing the front panel.
5.5 Configuration with DIP switches EN A number of settings can be changed using DIP switches (see appendix A, position M). A number of settings can be changed using DIP switches (see appendix A, position M). A note on used terminology: A system in which more than one Multi is used to create a single AC phase is called a parallel system. In this case one of the Multis will control the whole phase, this one is called the master.
Procedure The AC input current limit can be set using DIP switches ds8, ds7 and ds6 (default setting: 50A). Procedure: set the DIP switches to the required value: ds8 ds7 ds6 off off off = 6,3A off off on = 10A off on off = 12A off on on = 16A on off off = 20A on off on = 25A on on off = 30A on on on = 50A Remark: Manufacturer-specified continuous power ratings for small generators are sometimes inclined to be rather optimistic.

EN 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. Appendix 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.
One alarm LED lights and the second flashes. The charger does not operate. The inverter is switched off due to alarm activation by the lighted LED. The flashing LED indicates that the inverter was about to switch off due to the related alarm. The AC input voltage or frequency is not within the range set. 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.
7.2 Special LED indications EN (for the normal LED indications, see section 3.4) 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. The device will remain in normal operation.
All of the conditions below must be met!: The device is in error!
