8kW Single-Phase AC Output
The inverter provides:
- 8,000W rated AC output
- 8,800VA maximum apparent power
- Rated AC current: 36.4A / 34.8A
- Maximum AC current: 40A / 38.3A
- Maximum continuous AC passthrough: 50A
- Off-grid peak power: 2 × rated power for 10 seconds
- Power factor adjustment: 0.8 leading to 0.8 lagging
The inverter operates on 220/230V single-phase power with an L + N + PE grid connection.
Parallel System Expansion
The SUN-8K-SG05LP1-EU-SM2 supports up to 16 units in parallel for both on-grid and off-grid operation.
Multiple compatible batteries can also be connected in parallel, allowing the overall system to be configured around the required energy storage capacity.
This makes the inverter platform suitable for installations where power requirements may extend beyond the capacity of a single inverter.
AC Coupling
The inverter supports AC coupling, allowing it to be used in certain retrofit applications where an existing solar system needs to be expanded with additional hybrid functionality and battery storage.
This can provide an option for upgrading an existing installation without necessarily replacing every component of the original solar system.
Diesel Generator Energy Storage
The SUN-8K-SG05LP1-EU-SM2 supports storing energy from a diesel generator, providing an additional energy source for hybrid installations.
This can be particularly relevant for properties where solar, batteries and generator power need to operate together as part of an overall energy-management system.
Six Battery Charging & Discharging Periods
The inverter supports six configurable time periods for battery charging and discharging.
This allows the system to manage battery operation according to the installation’s energy-management requirements and available electricity sources.
High Efficiency
The Deye SUN-8K-SG05LP1-EU-SM2 provides:
- 97.6% maximum efficiency
- 96.5% Euro efficiency
- >99% MPPT efficiency
- Total current harmonic distortion: <3%
- DC injection current: <0.5%
These figures are specified in the supplied technical data.
