The MultiPlus-II is a multifunctional inverter/charger with all the features of the MultiPlus, plus an external current sensor option which extends the PowerControl and PowerAssist function.
The MultiPlus-II is ideally suited for professional marine, yachting, vehicle and land based off-grid applications.
It also has built-in anti-islanding functionality, and an increasingly long list of country approvals for ESS (Energy Storage System) application.
Several system configurations are possible.
PowerControl and PowerAssist - Boosting the capacity of the grid or a generator
A maximum grid or generator current can be set. The MultiPlus-II will then take account of other AC loads and use whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl function).
PowerAssist takes the principle of PowerControl to a further dimension. Where peak power is so often required only for a limited period, the MultiPlus-II will compensate insufficient generator, shore or grid power with power from the battery. When the load reduces, the spare power is used to recharge the battery.
Solar energy: AC power available even during a grid failure
The MultiPlus-II can be used in off grid as well as grid connected PV and other alternative energy systems. It is compatible with both solar charger controllers and grid-tie inverters.
Two AC Outputs
The main output has no break functionality. The MultiPlus-II takes over the supply to the connected loads in the event of a grid failure or when shore/generator power is disconnected. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.
The second output is live only when AC is available on the input of the MultiPlus-II. Loads that should not discharge the battery, like a water heater for example, can be connected to this output.
Virtually unlimited power thanks to parallel and three phase operation
Up to 6 Multis can operate in parallel to achieve higher power output. Six 48/5000/70 units, for example, will provide 25 kW / 30 kVA output power with 420 Amps charging capacity.
In addition to parallel connection, three units of the same model can be configured for three phase output. But that’s not all: up to 6 sets of three units can be parallel connected for a 75 kW / 90 kVA inverter and more than 1200 Amps charging capacity.
On-site system configuring, monitoring and control
Settings can be changed in a matter of minutes with VEConfigure software (computer or laptop and MK3-USB interface needed).
Several monitoring and control options are available: Color Control GX, Venus GX, Octo GX, CANvu GX, laptop, computer, Bluetooth (with the optional VE.Bus Smart dongle), Battery Monitor, Digital Multi Control Panel.
Remote configuring and monitoring
Install a Color Control GX or other GX product to connect to the internet. Operational data can be stored and displayed on Victrons's VRM (Victron Remote Management) website, free of charge. When connected to the internet, systems can be accessed remotely, and settings can be changed.
Provides intuitive system control and monitoring
Besides system monitoring and control the CCGX enables access to our free remote monitoring website: the VRM Online Portal
An inverter is a device that converts DC electricity into AC electricity, DC stands for Direct Current which is what we get out of batteries and solar panels. AC stands for Alternating Current, which almost everything in the world runs on as it allows the transmission of power across long distances.
In order to connect your battery or solar panel to the mains then you will need to convert the DC electricity into AC electricity – this is done via an inverter.
Inverters have been around for a long time but in the most recent years have become more sophisticated, especially with the popularity of solar panels.
he solar panels would link together and connect into a grid using a grid-tied inverter, often called a string inverter. This was revolutionary as the solar panels could connect directly to the mains electricity supply.
When the sun is shining the solar panel would produce power, which would then feed into the mains electricity. This is called AC Coupled/Grid-Tied.
Sunsynks Bi-directional Inverter
Sunsynk and their partners have invented a new type of inverter, called a bi-directional inverter. It is a device that connects between the battery and your mains AC connection.
This allows you to fast charge a storage battery during the day when AC power is cheap, saving the excess power that you’re not using, so that you can use your stored power in the evenings when energy prices are higher.
An additional device called a CT coil, which is included with the inverter, is used to detect any power that is not being exported and prevent it from feeding back to the mains.
It is a Bi-directional Inverter that can convert direct current into alternating current and alternating current into direct current. Therefore we can charge or discharge batteries at the same rated power.
Firstly, a separate charger is not required as we use the power of the inverter in reverse to charge the battery storage. If an inverter is rated at 3.6kW, it can both charge and discharge the battery storage at the same power of 3.6kW enabling on-grid and off-grid functions.
This means that you can charge your battery storage from the mains AC when the tariff is cheap and then discharge the battery to power your electronic devices ( the ‘Load’ ) when the mains AC tariff is expensive to use ie; Peak hours 5pm - 9pm.
To achieve this, after installation, the Sunsynk Inverter can be programmed via its touch screen or remotely via the Wi-Fi connection so that power can be fed in the correct direction at the chosen times.
The installation of battery storage along with a bi-directional inverter provides the user with an efficient means of reducing the amount of power consumed by an average household. In the event that your power demand exceeds the power coming from the inverter and batteries, the inverter will simply allow additional energy to be taken from the grid.
On-Grid mode means that your Inverter can take DC electricity generated by a solar array and convert it into AC electricity before sending to to the mains grid. In addition, it takes AC power from the grid and supplies it the batteries (to use later) and provides power to the load.
Off-Grid mode means the system relies on DC power generated by solar panels, wind turbines or generator and supplies DC power to the battery storage or AC power to the load.
A UPS can provide emergency power when an input source or mains power fails. The difference between a UPS and an emergency power system is that it provides near instantaneous protection from power interruptions by supplying power from the battery storage.
This will protect appliances such as computers , fridges and medical equipment where an unexpected power disruption could cause problems to the user.
A Sunsynk Bi-directional Inverter can achieve all of the above by visiting the LCD touch screen and setting the system operations.

Kodak Solar Off-Grid Inverter King
In rural or end-of-line locations, the AC grid voltage can fluctuate across a wide range. Voltage that is sufficently far from the nominal 230V can cause applicances to run much less efficiently, or make them unable to function.
Most other inverters that are capable of running in Island Mode simply pass through the variable grid voltage and only produce a smooth 230V supply in the event of a grid failure.
Kodak's King Off-Grid inverter is perfect for areas where grid electricity is less stable because it produces smooth 230V AC at all times, whether the grid is available or not.
This is great for efficient running of applicances, but crucial for an uninterrupted supply for important loads such as servers or ATMs.
- Built-in Bluetooth for mobile monitoring Detachable LCD control module with multiple communications (Android App is available)
- Supports USB On-the-Go function
- Reserved communication port for BMS (RS485)
- Parallel operation up to 9 units
- Robust UPS (uninterrupted power supply) for essential loads with zero transfer time
