    Figure 4.2 Solis S6 hybrid with export power control enabled Each Solis hybrid comes with an energy meter, which gets installed externally to the inverter. The energy meter uses two CTs, which measure the power being consumed and imported by the home.

  • Page 17: Energy Storage

    Battery S6 Hybrid Figure 4.3 Backup power with Solis S6 hybrid If the primary purpose of the energy storage system is to store as much of the PV power as possible so that it can be used later to offset the consumption of grid power, this is known as energy arbitrage.
  • Page 18 4. Operating Modes 4.2.2 Energy Arbitrage The S6 hybrid inverter has multiple operating modes which can be programmed so that the performance of the system is tailored to the specific needs of each individual system owner. The backup power function of the inverter can be enabled or disabled independently of the energy arbitrage modes:(1) Self-Use (2) Peak-Shaving (3) Feed-in-Priority Self-Use Mode Self-Use is the default energy storage mode.
  • Page 19 4. Operating Modes Feed-In-Priority Mode This mode can be thought of as export priority mode. The system will first supply the home loads with PV power and then it will seek to export the excess PV power, up to the set limit. Once the limit is reached, the remaining power will be stored in the battery.

  • Page 20: Dc Coupling Vs Ac Coupling

    DC-coupling methods.. 4.3.2 AC-Coupling The Solis S6 hybrid can be DC-coupled or AC-coupled to a home to add energy storage. In an AC-coupled the energy storage is connected to the AC-side of the system. Typically, the battery and Solis hybrid pairing get connected in parallel with an existing PV system.
  • Page 21 The maximum output power of the existing PV inverter must be less than the maximum output power of the Solis hybrid inverter. AC coupling can be done on either the grid side or the backup side. However, if it is on the backup side, then the max.output power of the existing PV inverter...

    4. Operating Modes 4.4 Partial-Home vs Whole-Home Backup This inverter is capable of providing AC power to home loads using PV and battery power in the event of a grid failure. When the inverter senses that the grid power has been lost, it automatically opens the relay between itself and the grid.
  • Page 23 47.5A on its own, to get a full 200A requires the addition of SolisHub with the inverter. SolisHub is designed to work with the Solis-S6EH1P(3.8-11.4)K-H-US inverter series. The purpose is to provide a seamless whole-home backup solution.

    Battery S6 Hybrid Figure 4.15 Backup with paralleled Solis hybrids It should first be determined what the maximum continuous current needs to be in order to meet the energy demand of the home. Up to three S6 hybrid inverters can be installed in parallel with PV and batteries to provide continuous backup power.

The Combiner is not required, but it does provide additional breaker slots to host multiple inveter breakers if one is installed.
  • Page 26 4.5.2 Power Control System (PCS) with SolisHub The Solis S6 hybrid inverter is UL 1741 PCS CRD certified. This means that the inverter is able to regulate the current and limit the loading on the busbars and conductors. The PCS can limit the power flow as to not exceed any busbar rating limits.

The system is permitted to charge the batteries with grid power and can discharge import discharge-export battery power to the grid.

  • Page 28: Generator Operation

    Figure 4.18 Off-grid system with a generator and no utility power The Solis hybrid can work with a generator that is also connected to a grid. However, an external ATS must be installed with the generator. This ATS would not be produced by Solis. When the grid is lost the ATS will disconnect from the grid but not start the generator until the inverter sends the start signal using dry contact.

    5. Installation 5.7 PV Cable Installation DANGER: Before installing the PV cables, be sure that the PV array is disconnected. Use a multimeter to verify that the PV string voltages are 0V before proceeding. If rapid shutdown is being used, then under 30Vdc per string is safe. Please verify the following before connecting the PV strings to the inverter: Ensure the DC voltage of the PV strings will not exceed the maximum DC input voltage (600Vdc).

  • Page 43: Rapid Shutdown

    5. Installation 5.8 Rapid Shutdown 5.8.1 Integrated Rapid Shutdown Important Note The inverter can be ordered with an internal rapid shutdown transmitter. This transmitter brand must match the receivers that are being installed with the PV modules. Not abiding by this will void the inverter warranty. How the inverter achieves module-level rapid shutdown: The internal transmitter generates a PLC signal when it receives AC power.
  • Page 44 Solis S6 hybrid inverter. 5.8.2 Photovoltaic Rapid Shutdown System (PVRSS) Certification The Solis S6 hybrid is PVRSS-certified with several brands that manufacture rapid shutdown equipment. The certification includes the inverter, the PLC transmitter, and the receivers.
  • Page 45 5. Installation 5.8.4 Cross-Talk Cross-talk occurs when competing PLC signals sent from different transmitters reach the same RSD receivers. This causes the receivers to randomly cycle on and off at various times. Cross-talk must be avoided at all costs. If multiple transmitters must be used, then it is important to keep the PV leads going from each inverter to the arrays separated by one foot minimum.
  • Page 46 5. Installation NOTE: Only remove the jumper when installing an external rapid shutdown switch. In all other cases, do not remove the jumper, as it may cause the inverter to stop. The external rapid shutdown initiation switch is sold separately. Please contact your local supplier for help with procurement.
  • Page 47 5. Installation Step 3: Locate the internal transmitter. The transmitter will be in the same place regardless of the brand. The only exception is Enteligent, which does not have an accessible transmitter and cannot be disabled. Shown below is an internal Tigo transmitter, for example. Step 4: Using a technician screwdriver, loosen the two terminals boxed in red.
