How do I start the inverter?

First, switch on the AC breaker. Then, turn on the DC switch of the PV module. The inverter will self-check and start generating energy once the grid parameters are within acceptable range. The NORMAL indicator light will turn on.

What should I do if the inverter displays an error code?

Refer to the error code table in the manual (Table 10.1). For example, F35 indicates no AC grid; check AC voltage and connections. If the issue persists after restarting, contact your installer or Deye service with the serial number and error details.

Can I use the inverter without an energy meter?

Yes, the inverter can operate without a meter. However, to enable zero-export or monitor load power, you must connect a compatible energy meter (e.g., Eastron SDM630-Modbus V2 or CHNT DTSU666) via RS485.

What are the recommended AC cable specifications?

For the SUN-80K-G, use 0 AWG copper cable (50 mm²) with a torque of 20.3 Nm for the AC terminals. For grounding, use 2 AWG (25 mm²) with 16.9 Nm torque.

How do I clean and maintain the inverter?

Turn off the inverter and let it cool. Use a soft brush to remove dust from the heatsink. If the LCD is dirty, use a slightly wet cloth. Do not use solvents, abrasive materials, or corrosive cleaners.

Is the inverter compatible with single-phase grids?

No, the SUN-80K-G is a three-phase inverter. It requires a three-phase grid connection with neutral and protective earth (3L+N+PE).

What is the Anti-PID function and how does it work?

The optional Anti-PID module repairs PID (Potential Induced Degradation) effects on PV modules at night. It operates automatically when the inverter is connected to AC. To disable it, turn off the AC switch.

How can I monitor the inverter remotely?

Install the WiFi or GPRS datalogger (included) into the inverter's communication port. Configure it using the provided instructions and connect to the Solarman monitoring platform (pro.solarmanpv.com for distributors, home.solarmanpv.com for end users).

What is the zero-export function and how do I set it up?

Zero-export prevents energy from being fed into the grid. Connect a compatible energy meter (e.g., Eastron SDM630) to the inverter's RS485 port. In the LCD menu, go to [Parameter Setting] > [Run Param], set 'Meter' to ON, and configure the meter settings. The inverter will then adjust output to match load consumption.

Pic 7.18 Zero-export function via energy meter turn on

1. Meter power 428W shows positive means grid is supplying the load, and no power fed into grid. if meter power shows negative, it means PV energy is being sold to grid or energy meter wiring connection has problem.
2. After properly connection is done, wait for inverter starting. If the power of the PV array meets the current power consumption, the inverter will keep a certain output to counteract the power of the grid without backflow.

7.1 Multiple strings and parallel connection meters

This application is that when the string inverters work in parallel, there is only one power grid and one load, and only one meter can be connected to prevent reverse current, so only this many-to-one anti-reverse current connection can be connected.

If there're several inverters parallelling operation in a plant, also it can use 1pcs meter to realize zero export function. For example, if there're 3pcs inverters parallelling operation in the system with 1pcs meter. We need to setup 1pcs inverteras the master and others setup as slaves. And, all of them need to connect to the meter via RS485. Below is the system diagram and configuration of the system.

7.2 How to browse the load power of your PV grid-tie plant on monitoring platform?

If you want to browse load power of the system and how much energy (KWH) does it export to grid(inverter output power is used to power the load firstly and then the surplus energy will feed into grid). You also need to connect the meter according to above diagram. After the connection completed successfully, the inverter will show the load power on the LCD. But please don’t setup “Meter ON”. Also, you will be able to browse the load power on the monitoring platform. The plant setting method as below description.

Firstly, go to the solarman platform(https://pro.solarmanpv.com, this link is for solarman distributor account; or https://home.solarmanpv.com, this link is for solarman end user account;) plant home page and click “edit”

And then choose your system type as "Self-consumption"

Secondly, go to plant page, if it shows the PV power, load power and grid power, which means the configuration is correct.

9. Repair and Maintenance

String type inverter doesn’t need regular maintenance. However, debris or dust will affect heat sink’s thermal performance. It is better to clean it with a soft brush. If the surface is too dirty and affect the reading of LCD and LED lamp, you can use wet cloth to clean it up.

High Temperature Hazard:

When the device is running, the local temperature is too high and the touch can cause burns. Turn off the inverter and wait for it cooling, then you can clean and maintain.

Safety Hint:

No solvent, abrasive materials or corrosive materials can be used for cleaning any parts of the inverter.
