Reasons to use the Sunsynk Inverter


1. The system can operate both in On-Grid and Off-Grid modes.

It can also be set as an Uninterruptible Power Source (UPS) where the inverter is combined with battery storage and connected to the main domestic power circuit via the LOAD output and can be programmed to provide power when the mains power is cut or there is insufficient power. This ensures your essential appliances remain with power.


What does this mean ?

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.


2. More than one inverter can be set in parallel to form larger systems.


What does this mean?


When inverters are connected in parallel their power output expands and their reliability improves. System redundancy also improves.

It is also necessary that if the inverters are set in parallel mode, the batteries should also be connected in parallel as this increases the stability of the system.


This will able the user to have a stable enlarged system with a larger solar array and expanded battery storage system. Sunsynk inverters are designed to do this.

3. It is a Bi-directional Inverter that can convert direct current into alternating current and alternating current into direct current.

Therefore it can charge or discharge batteries at the same rated power.


What does this mean?

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 South African 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.

4. It has MPPT [Maximum Peak Power Tracking] that allows the inverter to handle a solar array up to twice its size. 

For example, a 3.6kW Bi-directional Inverter has a 7.2kW MPPT which allows it to connect to a solar array of 7kW.

What does this mean?

The inverter is fitted with an input port which connects to the solar array. The port has the facility of MPPT which allows the inverter to maximise the energy available from the connected solar panels at any time during their operation.

During any day, the output from the solar panels ( the ‘array’)  will vary as sunshine changes its strength due to clouds and angle to the panels.

This means the power coming into the inverter will decrease at times. Now that the input has an MPPT circuit  it can constantly monitor and find the optimal voltage current array from which maximum power can be obtained all the time.

The Sunsynk 3.6kW Inverter matches 90% of UK-sized housing and allows the user to connect to a substantial solar array up to 7kW in size.

 Further enlargement is available due to the MPPT facility and other inverters and corresponding solar panels can be attached if more power is required.

5. It can divert excess power to your hot-water appliance automatically by power-shaving.

What does this mean?

When the solar panels are producing power, the system is set for Zero Export so that the power generated goes to the electrical appliances ( the ‘load’) Any surplus power is shaved-off and sent to appliances such as water heaters or into the battery storage for use later. This can be organised by adjusting settings on the inverter.

At the rear of the Sunsynk Inverter there are three connection ports :-

The right hand port is the grid connection.
The middle port is the auxiliary port and this has many different uses such as;
(i) A connection to a hot water tank to use extra power once the battery storage is full.
(ii) A generator for an off-grid system that can be activated by the inverter.
(iii) The port that should be used if additional inverters are connected.
3.   The left hand port is where the house fuse board is connected when running an Off-grid
system.
Therefore the middle port can provide power to appliances by power shaving extra power when the batteries are at maximum capacity.  


6. It has a colour touch-screen LCD which displays an easy-to-understand flow chart that contains the status of the inverter to help the user understand what the inverter is doing in real-time.










What does this mean?

This places the Sunsynk Inverter in a class of its own, especially the 3.6kW model that has its own touch screen that provides detailed information covering Battery / Power Supply / Solar Generation / Load (Appliances) / Battery Storage and Grid Power. Further display pages allow the user to set the functioning of the system ie; power export and power storage.



7. Unique Information Screen design. 

This allows the user a clear understanding of solar power production, battery charge status, the discharge of power and grid power consumption.


What does this mean?


After observing the status of the system the user is able to see how much power is being produced, how much is feeding into the house and how much is going into the battery storage. The user can adjust these amounts via the touch screen.



Our amazing platform and App that enables you to have full control of the system.  With the attachment of the Sunsynk Data Logger, the user of a Sunsynk solar system can remotely monitor and change any settings via a PC or mobile phone from any location around the world (provided there is an Internet connection).
