Frequently asked questions
Which of the three ratings do the Deye SUN7-7.6-8K-SG05LP1-EU-SM2 figures describe?
The designation of the Deye SUN7-7.6-8K-SG05LP1-EU-SM2 covers 7 kW, 7.6 kW and 8 kW builds, and the values recorded for this entry are 7000 W of nominal AC power and 7700 W of maximum AC power. Anyone comparing against the 7.6 or 8 kW versions should expect proportionally higher numbers than the ones listed here.
Is the Deye SUN7-7.6-8K-SG05LP1-EU-SM2 a transformerless inverter?
The inverter type recorded for the Deye SUN7-7.6-8K-SG05LP1-EU-SM2 is non-isolated, meaning no galvanic isolation transformer sits between the array and the grid. Omitting that stage saves weight and a conversion loss, which is part of how 97.6 percent maximum efficiency is reached, but it makes correct earthing and residual-current protection essential.
What grid does the Deye SUN7-7.6-8K-SG05LP1-EU-SM2 expect?
The Deye SUN7-7.6-8K-SG05LP1-EU-SM2 is recorded as single-phase with an AC output of 220 V at 50 Hz, a single configuration rather than a range. Sibling Deye units list a 220/230 V and 50/60 Hz spread instead, so on a nominal 230 V network the grid-code settings of the regional firmware are worth verifying.
Can the Deye SUN7-7.6-8K-SG05LP1-EU-SM2 handle two roof orientations?
Yes. The Deye SUN7-7.6-8K-SG05LP1-EU-SM2 has two MPPT channels, each recorded at 26 A of maximum DC input current and tracking between 150 V and 425 V under a 500 V input ceiling. Two independent trackers let an east and a west plane be optimised separately, and the equal current limits mean either array suits either input.
How is the Deye SUN7-7.6-8K-SG05LP1-EU-SM2 fixed to the wall?
The Deye SUN7-7.6-8K-SG05LP1-EU-SM2 weighs 26.8 kg and carries an IP65 rating with a -40 to +60 degree Celsius operating range, so an exterior wall is acceptable. At that weight two people and a substantial structural fixing are the sensible approach, and keeping it out of direct summer sun helps hold it inside its temperature limits.
What do the efficiency figures of the Deye SUN7-7.6-8K-SG05LP1-EU-SM2 mean?
The Deye SUN7-7.6-8K-SG05LP1-EU-SM2 is recorded at 97.6 percent maximum efficiency and 96.5 percent European efficiency. The European value, weighted across part-load operation, is the realistic basis for an annual yield estimate and implies roughly three and a half percent conversion loss. Harmonic distortion is listed separately at 3 percent.
