Discover the untapped potential of your solar energy system with the parallel operation option offered by Solis RHI 3 Phase inverters. In this article, we explore how this feature allows users to maximize energy production effortlessly. However, should any issues arise, the Solis support team is readily available to provide assistance and ensure a seamless solar experience. Let's delve into the world of parallel operation and empower users to harness the full power of the sun with confidence in reliable support. 

Note: The present scenario is not being displayed accurately on Soliscloud. Our dedicated Soliscloud Support team is actively addressing the issue to ensure that this scenario will be correctly displayed on our Soliscloud platform.

Applicable Devices:

• RHI-3P(3-10)K-HVES-5G
• Solis-EPM3-5G-PLUS
• Solis 3 phase PV inverters

Application Scenario:

The Solis-EPM3-5G-PLUS is installed at the system grid connection point as the sampling unit. And it communicates with multiple RHI-3P(3-10)K-HVES-5G and Solis 3 phase PV inverters to realize the self-use control logic

Below settings must be followed to ensure the correct control logic:

1.EPM

1.1 Transmit ON/OFF

Set to: OFF

Path: Advanced setting →Password :0010→Transmit ON/OFF→OFF

1.2. Address

Set to: 01

Path: Setting→Set address→01

1.3. Inverter Qty Set

Set to: Max number of slave address among all inverters

Path: Advanced setting→Password :0010→Inverter Qty →Set INV Number →Max number of slave address among all inverters

(Example: 3 hybrid inverters in parallel with slave address 02, 04, 06. Set Inverter Qty.Set to 06)

1.4. Set Capacity

Set to: Adding up the “Rated Power” of all inverters under the EPM

Path: Advanced setting→Password :0010→Set Capacity→Adding up the “Rated Power” of all inverters under the EPM

1.5. Set Meter CT

Set to: CT ratio of the external CT

Path: Advanced setting→Password :0010→Set Meter CT→CT ratio of the external CT

(Example: If 100A:5A CT are used, set the CT ratio as 20:1)

1.6. Backflow Power

Set to: Allowed backflow power.

Path: Advanced setting→Password :0010→Backflow Power→Set Power→Allowed backflow power.

1.7. Backflow work mode

Set to: 01

Path: Advanced setting→Password :0010→Backflow work mode→01

1.8. Inverter type

Set to: If there is a hybrid inverter, select “hybrid inverter”; If all with grid tied inverters, choose “PV inverter” 

Path: Advanced setting→Password :0010→Inverter Type→Hybrid inverter(If there is a hybrid inverter, select “hybrid inverter”; If all with grid tied inverters, choose “PV inverter”)

1.9.FailSafe ON/OFF

Set to:  Run

Path: Advanced setting→Password :0010→FailSafe ON/OFF→FailSafe:RUN

2. Solis 3 phase PV inverters

2.1 Set Address

Set to : Odd Number (01, 03,05, etc). Set to different on different inverters

Path: Setting→Set address→Odd number

2.2 Internal EPM Set

Set to : OFF

Path: Advanced setting→Password :0010→Internal EPM set→Mode Select: OFF

2.3 External EPM Set

Set to: ON

Path: Advanced setting →Password :0010→→External EPM set→5G-EPM →Fail Safe Set: ON

3.Hybrid inverters

3.1 Set Address

Set to : Even Number (02, 04,06, etc). Set to different on different inverters

Path: Setting→Set address→Even number

3.2 Meter Select

Set to: No Meter

Path: Advanced setting→Password:0010→Storage Energy Set→Meter Select→No meter

3.3 Int EPM Set

Set to: OFF

Path: Advanced setting→Password:0010→Int EPM Set→EPM ON/OFF→OFF

3.4 Ext EPM Set

Set to: ON

Path: Advanced setting→Password:0010→Ext EPM Set→Ext EPM ON/OFF→ON→Fail Safe ON/OFF→ON

3.5 Self Use Mode

Set to: ON and Allow grid charging

Path: Advanced setting→Password:0010→Stg Mode Select→Self use→ON→Charging from grid→Allow
