FAQs about the Deye Sun three-phase hybrid inverter
Which battery types are supported?
The inverter is compatible with lead-acid and lithium-ion batteries in the voltage range from 40 to 60V.
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 current is 350A each, which enables fast energy transfer.
What is the standby consumption of the device?
The Deye SUN-20K-SG05LP3-EU-SM2 has a self-consumption of ≤ 60 W.
Does the 20 kW inverter fit on an 18 kWp system or do I have to oversize/undersize?
Yes, the Deye SUN 20K-SG05LP3-EU-SM2 is technically optimised for an 18 kWp system. It does not necessarily have to be oversized or undersized. With a DC/AC ratio of around 0.9, it is exactly in the ideal range (0.9 - 1.1 is recommended). This means that the system is even slightly undersized, but this has practically no disadvantages and at the same time offers scope for retrofitting additional modules at a later date.
