Deye SUN800G3-EU-230 800 W grid-tied microinverter

The Deye SUN800G3-EU-230 is an 800 W grid-tied (on-grid) microinverter for two solar panels of 210–500 W each. It has 2 MPPT inputs, 96.5% peak efficiency, an IP67 enclosure and passive cooling, and communicates over PLC, WiFi or Zigbee. It is meant for solar systems where most of the electricity is used during the day; a battery cannot be connected to it.

Technical specifications

What is an 800 W microinverter used for?

The Deye 800 W microinverter suits sites that use electricity during the day, such as a workshop, an office, a shop or a farm with refrigeration or pumps. At such sites sunshine and consumption coincide, so a battery adds little. The microinverter converts the panels’ energy to grid voltage, feeds it to the building and sends any surplus to the grid.

How many solar panels can you connect, and which ones fit?

One SUN800G3-EU-230 takes 2 PV panels, each with a recommended input power of 210–500 W. It has 2 MPPT inputs, with 1 string connected to each. It is compatible with 60–72 cell panels; the MPPT voltage range is 25–55 V and the maximum DC input voltage is 60 V.

Connection, communication and the battery question

Up to 6 of these microinverters can be connected on one circuit. Monitoring runs over PLC, WiFi or Zigbee, and panel-level monitoring shows how each connected panel is performing. The microinverter has a rapid shutdown function and supports reactive power compensation.

No battery can be connected to this grid-tied microinverter, so in the evening, when the sun is gone, electricity is bought from the grid. ESO (Lithuanian grid operator) states the benefit of storage as follows, in translation:

“Part of the surplus electricity generated can be stored in an energy storage device and used in the evening.”

Microinverter or hybrid inverter?

If most of your electricity is used in the evening, it is worth comparing with a hybrid inverter, because storage needs a hybrid inverter or a separate storage inverter. Hybrid Energy also supplies hybrid inverters and helps you choose based on how much electricity you use by day and how much in the evening.

Frequently asked questions

What is the power of the Deye SUN800G3-EU-230?

The Deye SUN800G3-EU-230 has a rated output power of 800 W, a rated output current of 3.5 A and a nominal voltage of 230 V (range 184–265 V).

How many PV panels can be connected to the SUN800G3-EU-230 microinverter?

2 PV panels can be connected to the Deye SUN800G3-EU-230, each with a recommended input power of 210–500 W. The microinverter has 2 MPPT inputs, with 1 string connected to each.

Which panels suit the Deye microinverter?

The Deye SUN800G3-EU-230 is compatible with 60–72 cell PV panels. The MPPT voltage range is 25–55 V and the maximum DC input voltage is 60 V.

Can a battery be connected to the Deye SUN800G3-EU-230?

No, a battery cannot be connected to this grid-tied microinverter. Storage needs a hybrid inverter or a separate storage inverter, so if you plan to add storage later, it is worth allowing for that from the start.

What communication is used for monitoring?

The Deye SUN800G3-EU-230 supports PLC, WiFi or Zigbee communication. Its panel-level monitoring shows the performance of each connected PV panel.

What is the efficiency of the Deye SUN800G3-EU-230?

Peak inverter efficiency is 96.5%, CEC weighted efficiency is 95% and static MPPT efficiency is 99%. At night the microinverter draws 50 mW.

How many microinverters can be connected on one circuit?

Up to 6 Deye SUN800G3-EU-230 units can be connected on one circuit. Hybrid Energy helps you choose equipment for your site and your panels.

What warranty does the Deye SUN800G3-EU-230 have?

The Deye SUN800G3-EU-230 has a 10-year warranty. The enclosure is rated IP67, the ambient temperature range is -40 to +65 °C and cooling is passive.

How heavy and how big is the microinverter?

The Deye SUN800G3-EU-230 weighs 3.15 kg and measures 212 × 230 × 40 mm (without bracket and cable).

Does Hybrid Energy install the microinverter?
