Safety Hint:

Ensuring grid input cables connect 1/4/7/10 port of energy meter, and inverter AC output cables connect 3/6/9/10 port of energy meter when connecting.

1. Press Enter button on the LCD panel in the main interface into the menu options, select [parameter setting] to enter setup submenu, and then select [run param], at this time please input the default password 1234 through pressing the button [up down, enter], enter the operation parameter setting interface, shown as picture 7.17.

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.

    C --> D["Consumption Power 2.6kW"]

8. General Operation

During normal operation, the LCD shows the current status of the inverter, including the current power, total generation, a bar chart of power operation and inverter ID, etc. Press the Up key and the Down key to see the current DC voltage, DC current, AC voltage, AC current, inverter radiator temperature, software version number and Wifi connection state of the inverter.

Definition of Over-frequency Response Parameters

Parameter	Range	Description
StartPoint	45HZ-65HZ	The Start frequency value for over-frequency response.
StopPoint	45HZ-65HZ	The Stop frequency value for over-frequency response.
RecoverPoint	45HZ-65HZ	In hysteresis mode, power is restored only when it is below this frequency
RecoverGradient	0.3%-300% P/min	Ramp rate of power recovery
RecoverDelay	0-1000s	Time Delay of power recovery in hysteresis mode

Frq-Watt Mode for Overfrequency Conditions

When the frequency exceeds StopPoint: 51.5Hz, the inverter output should stop (ie 0 W).

When the frequency is lower than StopPoint: 51.5 Hz, the inverter will linearly increase the power output with a gradient of 100% Pmax/Hz until it reaches StopPoint: 50.5 Hz.

In the hysteresis mode, when the frequency is lower than StopPoint: 51.5 Hz, the inverter will not increase the power output until it is lower than RecoverPoint: 50.1 Hz.

The inverter provides a reactive power regulation function.

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.
