1. SAFETY INSTRUCTIONS General Please familiarize yourself with the safety features and instructions by first reading the documentation supplied with this product before using the equipment. This product has been designed and tested in accordance with international standards. The equipment must be used exclusively for the purpose for which it was designed. WARNING: ELECTRIC SHOCK HAZARD. The product is used in conjunction with a permanent energy source (battery).
Transport and Storage Ensure that the mains power and battery leads have been disconnected before storing or transporting the product. Appendix Ensure that the required system voltage does not exceed the product's capacity. EN Ensure that the equipment is used under the correct ambient conditions. Never operate the product in a wet or dusty environment. Ensure there is adequate free space for ventilation around the product and check that the ventilation vents are not blocked.
2. DESCRIPTION 2.1 General 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.
Appendix 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. In the Storage mode float voltage is reduced to 2,2V/cell (13,2V for 12V battery) to minimise gassing and corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to ‘equalize’ the battery.
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.
Appendix If the switch is not in the required position after following this procedure, it can be switched over quickly once. This will not change the charging state. EN 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”.

4. INSTALLATION 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. Excessively high ambient temperature will result in the following: Reduced service life. Reduced charging current. Reduced peak capacity, or shutdown of the inverter. Never mount the appliance directly above the batteries.
EN 4.2 Connection of Battery cables Recommended cross section 0-5m Recommended battery capacity (Ah) 12/2000 24/2000 70 mm² AWG 00 35 mm² AWG 2 24/2000 12/2000 200 – 500 350 – 1000 Appendix In order to fully utilize the full capacity of the product, batteries with sufficient capacity and battery cables with sufficient cross section should be used. See table. Remark: Internal resistance is the important factor when working with low capacity batteries.
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”.
