Frequently Asked Questions
Is this a standard 230V single-phase inverter?
This product is designed for split-phase applications, with 120/240V and 60Hz ratings. Verify the exact supply, configuration and destination-country requirements before ordering.
Can it work with a 51.2V LiFePO4 battery?
51.2V is within the 40–60V operating range. Confirm battery BMS communication, firmware, charge/discharge current and usable capacity before pairing.
Are all power variants identical?
No. Battery current is 120A, 135A, 190A and 190A for 5, 6, 7.6 and 8kW respectively. PV string inputs are 1+1, 2+1, 2+2 and 2+2; passthrough is 40A for 5/6kW and 50A for 7.6/8kW.
How long can it supply backup power?
Runtime depends on usable battery energy, load demand, battery limits and conversion losses. The inverter kW rating does not determine backup duration.
Can multiple units operate together?
Deye specifies up to 16 compatible units in parallel. Check firmware, communication, battery design and the exact manufacturer parallel wiring instructions.
What information is needed for a quotation?
Send the required power rating, country, grid voltage, battery model and quantity. Solarayen will confirm a suitable configuration, model availability and warranty terms.
