SINGLE PHASE INVERTER

ANTI-REVERSE WIRING

WHAT IS ANTI-REVERSECURRENT

FOR ONE PIECE GRID-TIED INVERTER

Limit the max power exporting to grid from solar system after feeding loads

× No need to use anti-reverse function

Pi: Inverter output power

Pl: Loads power

Pg: Power from/feed to grid

GOODWESINGLE-PHASE INVERTER

(NS / DNS SERIES)

CT - FROM GOODWE 1000 / 1, 90A

Anti-Reverse solution for a single phase inverter ( NS & DNS series )

1, Purchase a CT from GoodWe 2, Put CT on the main L line, and connect CT cable to inverter

3, Press 'Enter' button on the inverter to 'Set Power Limit'

Pi: Inverter output power

Pl: Loads power

Pg: Power from/feed to gridLimit Pg to 0 Limit Pg to a certain value

1 Finish wiring 2 Configure on inverter display

SINGLE PHASE

STEPS

THREE PHASE 1KW ~ 70KW

Scenario A: Pl = Pi + Pg

Scenario B: Pg = Pi – Pl

Logic:

Based on power limit value set on inverter display

Only works with goodwe CT

Anti-Reverse solution for a three phase inverter ( SDT & DT series )1, Purchase an EzMeter from GoodWe 2, Cut the Main L lines and then connect to EzMeter

3, A RS485 cable is used to communicate between inverter and EzMeter

4, Press inverter button to set the limit ON and Ratio

Logic:CT detects is there any or how much current stream flowing to/from the grid, then it sends signal to tell inverter to reduce or increase output power accordingly.

3-phase EzMeter communicates with the inverter and detects (on each phase) if there is any or how much current stream flowing to/from grid, then feedbacks the data to the inverter, which will know how much power (in total) it should produce after calculation.

1, Purchase an EzMeter from GoodWe and CTs from GoodWe or anywhere else 2, Put CTs on main L lines and connect CT cables to EzMeter CT ports

3, Connect L lines and Neutral line from anywhere to EzMeter power ports 4, An RS485 cable is used to communicate between inverter and EzMeter

5, Press EzMeter button to set CT ratio 6, Press inverter button to set the limit ON and Ratio

3-phase EzMeter communicates with inverter and CT detects (on each phase) is there any or how much current stream flowing to/from grid, then feedbacks data to the inverter, which tells how much power (in total) it should produce after calculation.

Note: CT is available from GoodWe or from external vendor (Ratio: ***/5A)

For the connection, CT1 (connected on Ia & Ia*) must be connected to the same phase line with Ua, same for CT2 & Ub, CT3 & Uc.

Wrong wir ing wil l cause inaccurate data detection which further lead to malfunction of solar system

EzMeter + CT detect curent flow and communicate with hybrid inverter, then inverter will keep extra power charging battery or drop inverter production to achieve power export limit.

1, Purchase a CT & EzMeter unit from GoodWe

2, Put CT on the main L line, and connect Ethernet cable from inverter to EzMeter

3, Connect inverter wireless signal ‘Solar-WiFi’ with a phone and run PV Master app

4, Switch ‘Export Power Limit’ to ON and set ‘Power Value’
