What is a three-phase hybrid inverter for?
The Deye SUN-6K-SG05LP3-EU-SM2 is designed for homes and businesses with a three-phase 230/400 V connection, where solar energy, a battery and the grid work as one system.
- A new solar system with a battery
- Adding to an existing solar system through AC coupling
- Power during a grid outage, including operation with a diesel generator
- Optimising consumption by tariff: 6 programmable charge and discharge periods
Hybrid inverter with battery: which batteries are compatible?
This inverter takes one 48 V (40–60 V) low-voltage battery (transformer isolation), lithium-ion or lead-acid, with a maximum charge and discharge current of 135 A. Li-ion charging adapts to the battery’s BMS. Several batteries in parallel are supported, and we choose the specific models after checking compatibility.
How much solar power can you connect to a 6 kW hybrid inverter?
Maximum PV input power is 9,000 W.
The inverter has two MPPT trackers with one string each (1+1), with up to 20 A per input. The MPPT voltage range is 200–650 V, start-up voltage 160 V and maximum input voltage 800 V. We work out the exact panel count from string voltage and current before you order.
Backup power and unbalanced load
When grid voltage is lost, the inverter can work with a diesel generator and, in off-grid mode, deliver up to 12,000 W for 10 s. In a three-phase system, 100 % unbalanced load is allowed on each phase, with output of up to 50 % of rated power.
How to connect a hybrid inverter to the grid and a storage battery
The inverter complies with grid codes including EN 50549 and VDE-AR-N 4105, and up to 10 units can run in parallel in grid-connected and off-grid mode. ESO (Lithuanian grid operator) states:
“Part of the surplus electricity generated can be stored in an energy storage device and used in the evening.”
We handle it for you. We select the equipment for your site, deliver anywhere in Lithuania, install and connect it.
