Victron MultiPlus-II 3000VA 48V inverter with 35A charger 48/3000/35-32 230V
The MultiPlus-II 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.
Photonic Universe is an official distributor of products from Victron Energy - the globally renowned manufacturer of high quality hybrid power electronics. Victron Energy inverters have a longstanding reputation for their outstanding reliability, innovative design and superior build quality.
The 48/3000/35-32 MultiPlus-II intelligently combines the functions of a powerful 3000VA 48V pure sine wave inverter, a sophisticated 35A battery charger which features adaptive charge technology, and a high speed 32A AC transfer switch in one single unit. This makes the MultiPlus-II ideal for applications with limited space, and allows you to have a more compact and easy-to-troubleshoot system, especially since using the MultiPlus-II will require less cables compared to using separate units (i.e., separate inverter, battery charger, and AC transfer switch).
Key functions:
1. 3000VA 48V pure sine wave inverter: converts DC current into 230VAC mains electricity, to run various household appliances such as a TV, laptop, lighting, fans etc. Able to generate up to 2400W of continuous power with a strong peak power handling capability of 5500W (to start appliances with electric motors). This inverter is a pure sine wave type, which easily surpasses modified sine wave inverters in terms of efficiency and compatibility with a wider range of appliances.
2. Adaptive 35A 4-stage smart battery charger (bulk - absorption - float - storage): designed to enable safe and efficient unattended charging of a 48V battery. The microprocessor-driven adaptive battery management system can be adjusted for various types of batteries, and the adaptive function automatically adapts the charging process to battery use.
3. Uninterruptible power supply (UPS): This inverter/charger features a high-speed 32A AC transfer switch. This means that in the event of a grid failure, or shore or generator power being disconnected, the inverter within the MultiPlus-II is automatically activated and takes over supply to the connected loads. This happens so fast (less than 20 milliseconds) that sensitive loads (such as computers and other electronic devices) will continue to operate without disruption, eliminating the risk of losing data.
Additional intelligent features:
The MultiPlus-II has all the features of the standard MultiPlus inverter/chargers, plus an external current sensor option which extends the PowerControl and PowerAssist functions and optimises self-consumption (external current sensor not included). Furthermore, the MultiPlus-II has an auxiliary AC output (AC-out-2) intended for non-critical loads; the equipment connected to AC-out-2 may only operate if AC input voltage is available, and is disconnected immediately when the MultiPlus-II switches to battery operation (i.e., inverter mode).
In addition to the above, the MultiPlus-II offers several additional features and customisable settings that provide a range of useful applications and enhanced functionality; these include but are not limited to:
- PowerControl: This feature allows the user to set the maximum AC input current to be drawn by the MultiPlus-II, for the battery charger and the connected AC loads consumption, and gives priority to the AC loads. This way, the MultiPlus-II prioritises the power/current supply to the connected AC appliances, and whatever current is “left over” is used to charge the batteries. This keeps your system from overloading the AC supply (e.g., generator or shore supply) and prevents the circuit breaker from tripping. This feature requires the Multi Control Panel (not included).
- PowerAssist: This feature allows the MultiPlus-II to supplement the capacity of the AC power source. Meaning, in the case of the AC appliances requiring more current than the AC source can supply, the MultiPlus-II’s bidirectional converter operates as an inverter, in parallel with the AC input, and provides additional current from the battery to meet the AC load current demand. Once this demand decreases, the spare power from the AC source is used to recharge the battery/battery bank. In applications where peak power is required only for a limited period, the PowerAssist feature allows you to use a smaller generator to power your equipment; or, alternatively, it allows more to be achieved from a limited shore.
- Programmable relay: The MultiPlus-II is equipped with a programmable relay which can be programmed for all kinds of applications, such as providing a start/stop signal to a generator. By default, the programmable relay is set as an alarm relay; i.e., the relay will de-energise in the event of an alarm or a pre-alarm (inverter almost too hot, ripple on the input almost too high, battery voltage almost too low).
- Parallel and 3-phase operation capability: The MultiPlus-II can be connected in parallel with several identical devices (up to 6) to achieve higher power output. Operation in 3-phase wye (Y) configuration is also possible. A standard RJ45 UTP cable is required for parallel and 3-phase operation (not included).
- Inbuilt safety protection: The MultiPlus-II offers complete protection against potential hazards such as output short circuit, overload, battery overvoltage & undervoltage, overheating, 230 VAC on inverter output (e.g., from another AC source), and input voltage ripple that is too high.
- WeakAC: Strong distortion of the input voltage can result in the charger hardly operating or not operating at all. If WeakAC is turned on, the charger will also accept a strongly distorted voltage, at the cost of greater distortion of the input current.
- BatterySafe mode: 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.
- 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 minimise gassing and corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to “equalise” the battery. This feature prevents stratification of the electrolyte and sulphation, 2 major causes of early battery failure.
- PowerControl: This feature allows the user to set the maximum AC input current to be drawn by the MultiPlus-II, for the battery charger and the connected AC loads consumption, and gives priority to the AC loads. This way, the MultiPlus-II prioritises the power/current supply to the connected AC appliances, and whatever current is “left over” is used to charge the batteries. This keeps your system from overloading the AC supply (e.g., generator or shore supply) and prevents the circuit breaker from tripping. This feature requires the Multi Control Panel (not included).
