FAQ
Q: Can I connect multiple grid-tied inverters to the S6 Solis Hybrid inverter?
A: Yes, you can connect multiple grid-tied inverters in parallel, but additional devices like EPM or S3-Logger are required to enable Feed-in limitation.
Q: What should I do if I want to connect the system to a generator?
A: If you want to connect the system to a generator, do not connect a grid- tied inverter simultaneously to avoid the risk of damaging the generator.
Overview
This document explains the process of AC Coupling when a Grid-Tied PV inverter
is connected to either the backup output or the generator port of a S6 Solis
Hybrid inverter as displayed in the diagrams below.
Inverters can be connected to the AC Backup port when a Generator is connected
to the Generator port.
NOTE
- Grid-tied inverter can be connected via AC-Gen port and AC-Backup port.
- With existing PV Plant connected to the system， it is recommended that the grid-tied inverter power＜ rated AC power of S6 inverter.
- In on-grid scenario,when the third-party grid-connected inverter is connected, the system cannot control the output power of the third-party grid-tied inverter, so Feed-in limitation cannot be realized ;
- When connected in off-grid scenario, the third-party grid-tied inverter needs to set the correct grid code and has the function of over-frequency load shedding & under-frequency load rising, so that the system can adjust the frequency to control the output power of the grid-tied inverter.
- The Solis grid-connected inverter can be connected with Hybrid inverter in parallel . In order to realize Feed-in limitation, it is necessary to add EPM or S3-Logger devices.
- When the system is connected to the generator, it cannot be connected to the grid-tied inverter, because of a risk of damaging the generator
- Step 1 – Logging into the Hybrid Inverter locally.
- Step 2 – Hybrid Inverter Parameter Settings
- Step 3 – Setting up the PV Grid-Tied Inverter
Method
Step 2.4: Select Connect with Bluetooth
AC Coupling Settings on the S6-Hybrid Inverter
- Step 3.1: Select the AC Couple Settings for Set up settings
- Step 3.2: Switch the AC Coupling switch setting on, as per below screenshot.
Parameter Settings
- AC Coupling switch must be turned on.
- Two positions for connecting the grid-tied inverter as possible depending on whether a generator is used or not.
- a. Gen Port: Set the Gen Port position if the grid-tied inverter is installed on the inverter’s generator port.
- b. Backup Port: Set the Backup position when the grid-tied inverter is coupled to the inverter’s backup output.
- AC Coupling OFF SOC must be set to the required percentage.
- AC Coupling Max value is the Stop value of 52.7Hz set on the battery inverter and must be set the same on the AC PV inverter. Example: Start 51Hz and Stop 52.7Hz
- The “GEN Port load open switch” must also be switched on and can be found in Smart port setting under GEN settings.
Settings on the PV Inverter
See Below images as reference on AC PV Inverter.
Go to Settings and then set the time and date as well as the Inverter address
as shown below.
Frequency set up
Go to Advanced Settings Password is 0010 and follow below set up.
EPM Settings
Set the Back Flow Work Mode to (Average mode)
Check that the CT’s are measuring a negative Watt reading with No solar production. This would indicate that the CT’s are in the correct position.
You can get this information from the Information tab on the EPM.
