Can Sunsynk provide a UPS (Uninterruptable Power Source) system for AC Grid Power Outages

Yes, Sunsynk Inverters and Batteries can operate as a UPS Back Up system.

Sunsynk Inverters have programmable multiple operation modes for on-grid/off-grid & UPS.

Reason number 8 of "10 Reasons To Use Sunsynk Inverter And Battery System" on the Sunsynk website states:-

8 - 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. 

The customer will need to advise which circuits of their House Load that they want to be powered as essential (immersion heater, lights, freezer etc) in the event of any power cut. These circuits can be disconnected from the House Consumer Unit / Distribution Board and connected to the Load output of the Inverter via a separate Consumer Unit. When AC Grid is available the AC power is passed through to the Load output. When the AC power is lost the Load output is powered by AC from the Inverter with the source being the DC from the Storage Batteries.

Size of Inverter and size of Storage Batteries required for the design of the Plant will need to be determined from the customers specifications.
