. Zero-export function via energy meter
There’re four kinds of energy meters for this series inverter. First type is Eastron SDM-Modbus V which is able to measure the Max. A current directly. More details please refer to Pic . & .. For the Eastron SDM MCT mA, it needs external CT to measure the current. The CT power range is from A-A. More details about the Eastron SDM MCT, please refer to Pic . & .. Also, the CHNT meter DTSU is supported, it can measure the Max. A current directly. More details about the DTSU, please refer to Pic . – .. When you are reading this, we believe that you have completed the connection according to the requirements of chapter , if you have been running your inverter at this time, and you want to use the zero-export function, please turn off AC and DC switch of the inverter, and wait for minutes until the inverter completely discharged. For system wiring diagram, the red line refers to L line (L, L, L), the black line refers to the neutral line (N). Connecting energy meter RS cable to inverter’s RS port. It’s recommended to install an AC switch between the inverter and the utility grid, the specs of the AC switch are determined by the power of load. If there is no integrated DC switch inside the inverter you purchased, we commend you to connect the DC switch. The voltage and current of the switch depend on the PV array you access.

. Meter power W 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 conncetion has problem.
. 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 .
– –

. 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 pcs meter to realize zero export function.For example, if there’re pcs inverters parallelling operation in the system with pcs meter.We need to setup pcs inverteras the master and others setup as slaves. And, all of them need to connect to the meter via RS.Below is the system diagram and configuration of the system.

. 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”

Time Delay of power recovery in hysteresis mode
Response delay time after entering active power frequency mode

For example, StartPoint: .Hz, StopPoint: .Hz, RecoverPoint: .Hz, when the grid frequency increases beyond StartPoint: .Hz, the inverter will linearly reduce the power output with a gradient of % Pmax/Hz until it reaches StopPoint: .Hz.

When the frequency exceeds StopPoint: .Hz, the inverter output should stop (ie W). When the frequency is lower than StopPoint: . Hz, the inverter will linearly increase the power output with a gradient of % Pmax/Hz until it reaches StopPoint: . Hz. In the hysteresis mode, when the frequency is lower than StopPoint: . Hz, the inverter will not increase the power output until it is lower than RecoverPoint: . Hz.

The inverter provides a reactive power regulation function. Tap Reactive Power Regulation Mode to select proper regulation mode and set the corresponding parameters.
“OFF” Mode The reactive power regulation function is disabled. The PF is fixed at +.
ReactiveP Adjust reactive power output in %.
“PF” Mode
The power factor (PF) is fixed and the reactive power is regulated by the parameter PF. The PF ranges from . leading to . lagging.
·Leading: the inverter is sourcing reactive power to the grid. ·Lagging: the inverter is injecting reactive power into the grid. “Q(U)” Mode
The reactive power output of the inverter varies in response to the grid voltage.
“Q(P)” Mode
The reactive power output by the inverter is controlled by the active power of the inverter.

. 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.
.Error information and processing
Inverter has been designed in accordance with international grid tied standards for safety, and electromagnetic compatibility requirements. Before delivering to the customer the inverter has been subjected to several tests to ensure its optimal operation and reliability.
. Error code
If there is any failure,the LCD screen will display an alarm message. In this case, the inverter may stop feeding energy into the grid. The alarm description and their corresponding alarm messages are listed Table ..
