Backup and Off-Grid Operation
One of the major advantages of the Sunsynk hybrid platform is its ability to manage energy intelligently during grid-connected and backup operation.
When sufficient solar power is available, the system can prioritise solar energy for connected loads while charging the battery with surplus energy. Stored battery energy can then be used when solar production is low or when the grid is unavailable.
In an appropriately designed installation, the inverter can therefore help maintain power to essential loads during grid outages.
Intelligent Energy Management
The inverter is designed to optimise energy usage by coordinating:
- Solar PV generation
- Battery charging and discharging
- Grid electricity
- Backup loads
- AC input sources
- Energy consumption
This allows users to increase self-consumption of solar energy, reduce reliance on grid electricity and make better use of available battery storage.
WiFi Monitoring Included
The inverter is supplied with WiFi monitoring functionality, allowing users and installers to monitor the solar system remotely.
Depending on the system configuration and monitoring platform, users can view important operating information such as:
- Solar PV production
- Battery state and charging status
- Battery charge/discharge activity
- Grid import and export
- Load consumption
- Inverter operating status
- Historical energy performance
- System alarms and operating information
Remote monitoring is particularly useful for installers and system owners who want to identify performance issues without needing to access the inverter physically.
High Efficiency
The Sunsynk 8kW inverter is designed for efficient energy conversion, helping reduce losses between the solar array, battery and connected loads.
- Maximum efficiency: 97.60%
- Euro efficiency: 96.50%
- MPPT efficiency: >99%
- Total current harmonic distortion (THDi): <3% of nominal power
- DC injection current: <0.5% In
The high MPPT efficiency helps the inverter extract as much usable energy as possible from the connected solar array.
Multiple MPPT Trackers
The inverter incorporates two MPPT trackers, with 2 + 2 PV strings supported according to the datasheet configuration.
Having separate MPPT tracking allows the solar array to be configured more flexibly. This can be beneficial where panels are installed on different roof orientations or where different string configurations are required.
Grid Connection
The Sunsynk 8kW is designed for single-phase electrical systems and uses an L + N + PE grid connection configuration.
The rated input/output voltage is 220/230V, with a specified operating voltage range of 0.85–1.1 × Un.
The inverter supports both 50Hz and 60Hz operating frequency ranges according to the applicable configuration.
Protection and Safety Features
The inverter incorporates multiple electrical protection functions designed to help protect the inverter, battery, solar array and connected loads.
Protection-related specifications include:
- Output overcurrent protection
- High output fault-current handling
- DC injection current control
- PV input current monitoring
- PV short-circuit current handling
- Battery charging/discharging control
- BMS communication for compatible lithium batteries
- Grid voltage and frequency monitoring
Correct installation, configuration and protection equipment must always be provided in accordance with the manufacturer’s requirements and applicable electrical regulations.
Ideal Applications
The Sunsynk 8kW 48V hybrid inverter is suitable for a wide variety of applications, including:
Residential Solar Systems
Ideal for larger homes with higher electricity consumption and multiple high-demand appliances.
Backup Power Systems
Suitable for installations requiring battery-backed power during grid outages.

Off-Grid and Hybrid Installations
Suitable for hybrid and off-grid energy systems where the inverter is correctly configured with compatible battery storage and solar PV equipment.
Recommended System Configuration
A typical installation may include: Solar Panels → Sunsynk 8kW Hybrid Inverter → Household/Commercial Loads
with: 48V Battery Bank ↔ Sunsynk 8kW Hybrid Inverter
and: Utility Grid ↔ Sunsynk 8kW Hybrid Inverter
The inverter intelligently manages the available energy sources according to the configured operating mode, load requirements, battery condition and solar production.
Important Installation Considerations
The actual solar panel quantity and string configuration must be determined using the panel’s Voc, Vmp, Isc and Imp values, together with the expected minimum and maximum site temperatures.
For the 8kW model, particular attention should be paid to:
- Maximum PV voltage of 500V
- MPPT operating range of 150–425V
- Maximum PV input current of 26A + 26A
- Maximum PV short-circuit current of 34A + 34A
- Maximum PV input power of 12,800W
- Maximum PV access power of 16,000W
