EN 2. DESCRIPTION 2.1 General Appendix Multi Compact -functional The MultiPlus Compact gets its name from the multiple functions it can perform. It is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive charge technology and a high-speed AC transfer switch in a single compact enclosure. Beside these primary functions, however, the MultiPlus Compact has several advanced features that provide a range of new applications as outlined below.
If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen, damage due to excessive gassing will be prevented by automatically limiting the rate of voltage increase once the gassing voltage has been reached. Less maintenance and aging when the battery is not in use: the Storage mode The Storage mode kicks in whenever the battery has not been subjected to discharge during 24 hours.
EN 3. OPERATION 3.1 On/Off/Charger Only Switch Appendix 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.
3.3.3 Activating equalisation or forced absorption The MultiPlus can be put into both these states from the remote panel as well as with the front panel switch, provided that all switches (front, remote and panel) are set to “on” and no switches are set to “charger only”. In order to put the MultiPlus in this state, the procedure below should be followed. If the switch is not in the required position after following this procedure, it can be switched over quickly once.

EN 4. INSTALLATION Appendix This product should be installed by a qualified electrician. 4.2 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. The product is suitable for wall mounting. For mounting see appendix A. The appliance can be mounted horizontally as well as vertically; vertical mounting is preferable. The vertical position offers optimum cooling.
Each system requires a method of disconnecting the AC and DC circuits. If the overcurrent protection device is a circuit breaker, it will also serve as the disconnect. If fuses are used, separate disconnect switches will be needed between the source and the fuses. To reduce the risk of fire, do not connect to an ac load center (circuit breaker panel) having multiwire branch circuits connected. CAUTION – To reduce risk of injury, charge only Lead Acid or LIFEPO4 type rechargeable batteries.
PERSONAL PRECAUTIONS iii. Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery. iv. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flood eye with running cold water for at least 10 min and get medical attention immediately. v. NEVER smoke or allow a spark or flame in vicinity of battery or engine. vi. Be extra cautious to reduce risk of dropping a metal tool onto battery.
• Locate marine unit away from battery in a separate, well ventilated compartment. • Never place marine unit directly above battery; gases from battery will corrode and damage marine unit. • Never allow battery acid to drip on marine unit when reading gravity or filling battery. • Do not operate marine unit in a closed-in area or restrict ventilation in any way.
Appendix Procedure Proceed as follows to connect the battery cables: EN Remark: Internal resistance is the important factor when working with low capacity batteries. Please consult your supplier or the relevant sections of our book “electricity on board”, downloadable from our website. Use an insulated box spanner in order to avoid shorting the battery. Avoid shorting the battery cables. Connect the battery cables: the + (red) on the left and the - (black) on the right, to the battery see appendix A.
4.3 Connection of the AC cabling This is a Safety Class I product (supplied with a protective grounding terminal). Uninterruptible protective grounding must be provided at the AC input and/or output terminals and/or chassis grounding point located externally on the product. 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.
EN 4.4 Optional Connections 4.4.1 Second Battery The MultiPlus Compact has a connection (+) for charging a starter battery. For connection see appendix A. Appendix A number of optional connections are possible: Undo the four screws at the front of the enclosure and remove the front panel. 4.4.2 Temperature Sensor The temperature sensor supplied with the product may be used for temperaturecompensated charging. The sensor is insulated and must be mounted on the batteries minus pole.
4.4.5 Parallel Connection The MultiPlus can be connected in parallel with several identical devices. To this end, a connection is established between the devices by means of standard RJ45 UTP cables. The system (one or more Multis plus optional control panel) will require subsequent configuration (see Section 5). In the event of connecting MultiPlus units in parallel, the following requirements must be met: • A maximum of six units connected in parallel.
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. Appendix Settings may only be changed by a qualified engineer Carefully read the instructions before changes are made. Batteries should be placed in a dry and well-ventilated area during charging. EN 5.
5.2 Explanation of settings Settings that are not self-explanatory are described briefly below. For further information, please refer to the help files in the software configuration programs (see Section 5.3). Inverter frequency Output frequency if no AC is present at the input. Adjustability: 50Hz; 60Hz Input frequency range Input frequency range accepted by the MultiPlus. The MultiPlus synchronises within this range with the AC input frequency. The output frequency is then equal to the input frequency.
EN Appendix AES (Automatic Economy Switch) Instead of the search mode, the AES can also be chosen (with help of VEConfigure only). If this setting is turned ‘on’, the power consumption in no-load operation and with low loads is decreased by approx. 20%, by slightly 'narrowing' the sinusoidal voltage. Not adjustable with DIP switches. Applicable in stand-alone configuration only.
Bulk Protection When this setting is ‘on’, the bulk charging time is limited to 10 hours. A longer charging time could indicate a system error (e.g. a battery cell short-circuit). Not adjustable with DIP switches. AC input current limit These are the current limit settings at which PowerControl and PowerAssist come into operation. The factory setting is 30A. See Section 2, the book 'Energy Unlimited', or the many descriptions of this unique feature on our website www.victronenergy.com .
EN Appendix WeakAC Strong distortion of the input voltage can result in the charger hardly operating or not operating at all. If WeakAC is set, the charger will also accept a strongly distorted voltage, at the cost of greater distortion of the input current. Recommendation: Turn WeakAC on if the charger is hardly charging or not charging at all (which is quite rare!).
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). Some settings can be changed with DIP switches (see Section 5.2). 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.Bus to USB) interface. Alternatively, the Interface MK2.2b (VE.
Some settings can be changed with DIP switches Appendix Procedure: a) Turn the Compact on, preferably without load and without AC voltage on the inputs. The Compact will then operate in inverter mode. b) Set the dipswitches as required. c) Store the settings by moving Dip switch 8 to “on” and back to “off”.
