FAQs on the Deye Sun three-phase hybrid inverter
Which battery types are supported?
The inverter is compatible with lead-acid and lithium-ion batteries within a voltage range of 40 to 60 V.
Can I operate several devices in parallel?
Yes, up to 10 units can be operated in parallel, making the inverter ideal for larger systems.
What is the maximum charging and discharging current?
The maximum charging and discharging currents are both 350A, which enables rapid energy transfer.
What is the unit’s standby power consumption?
The Deye SUN-20K-SG05LP3-EU-SM2 has a power consumption of ≤ 60 W.
Will the 20 kW inverter fit an 18 kWp system, or do I need to oversize or undersize it?
Yes, the Deye SUN 20K-SG05LP3-EU-SM2 is technically ideal for an 18 kWp system. It does not need to be either oversized or undersized. With a DC/AC ratio of around 0.9, it falls exactly within the ideal range (0.9–1.1 is recommended). This means the system is actually slightly undersized, but this has practically no disadvantages and, at the same time, allows scope for retrofitting additional modules at a later date.
