## 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.
