New Release: Sunny Island 6.0H / 8.0H Now Even Faster To Battery Operation

The Sunny Island battery inverter supports a wide range of on- and off-grid installations with compelling product features—from operation in off-grid areas to home energy management. With the new release, it changes to battery operation even faster if the grid fails.

Current release Sunny Island

Is your off-grid system experiencing a generator or grid failure? That’s no problem for the Sunny Island 6.0 and 8.0. With the new release R1.3, the inverter changes from grid to battery operation within 0 to 20 ms, ensuring that many critical loads receive an uninterrupted supply of power.

The update also offers benefits for grid-connected systems:

  • New Webconnect 1.5
  • Much-improved WLAN configuration
  • Integrated web interface features clearer design
  • Current-controlled operating mode for more stable operation in weak utility grids

    I have 2 sunny island 8 both on the new firmware. I am off grid with only a generator. I can do a full charge 100% (58.24 volts) with the generator but am unable to do a full charge using solar only. When charging from solar only, at best i will only get 88%, as the charging voltage is too low to achive a full charge (57.7 volts). I have had this system installed now for 8 months. I am using lithium batteries and REC bms. Can the sunny island achive a full charge off grid, connected to lithium batteries, without using the generator??

      Hi Ivan,
      It´s possible to achieve full charge just with solar. Maybe in this case the solar energy was not enough to fulfill the charge? Please note that there should not be any loads or a big excess of PV-energy to reach 100% solar energy charging.
      Kind regards, Anke

        Hi, we’ve had very good solar exposure today, and the set charging voltage still remains at 57.7 volts (88%)and the sunny island frequency will raise to cut off the charging, the system will only charge to 100% when I set the generator to manually come on the set voltage will change to 58.7 volts and full charge can be achieved.

    Is there an “expert mode” on the new sunny islands?? I have the sunny remote then found out there is no connection for it.

      Hi Ivan,
      Sorry to hear that you didn´t get a reply yet.
      Please find the answers to your questions:
      There is no there “Expert mode” anymore in the new SI -12. You can choose “installator” or “user”.

      To answer your first question: In the charging process voltage can increase, depending on the size of the current. Please also check the battery temperature as it normally increases, too. The voltage is quite high for 88% SOC, that`s why the SI does not charge more. The Sunny Island starts with the FSPC to protect the batteries for an overcharge! So please never try to charge the battery with the generator if the SI starts with the FSPC!
      I hope this helps.
      Kind regards,
      Anke

    Hello, I have three sunny island SI 6.0 configured for three phase which I don’t require any longer. Is it possible to have them setup for three separate single phase units. Thanks

      Hi Andre,
      Yes, you can use the SI in a 3 separate single phase systems. You just need to make a new commissioning. Please note that each SI-system needs its own battery bank.

    These are lithium batteries, full charge 100% soc would be 58.7 v, this is the correct set voltage as indicated when the gen set is on. When the gen set is off, and normal charge is happening from sunny boys the sunny island defaults to 57.7 volts for charging, which will only give an 88% soc.

    I’ve seen in the parameter list there is settings for the bms, but i cannot see these parameters in the sunny island web user interface.

      Hi Ivan,
      This is normal as the battery management system (BMS) from the SI is disconnected once you set the SI working with a Li-ion battery. The BMS of the battery is the one that takes the control of these charge/discharge voltages. It´s not possible to modify the parameters as they are set by the battery manufacturer.

    Hi

    I have six sunny islands with MC box 6.3 for one of our off-grid project.
    Old Sunny island used to have very detail settings via Sunny remote controller, and they are listed in operating manual.
    New sunny island seems to be simplified for the parameters. Do you have new list of parameters? It would be great if you can let me know where to find the information.

    cheers,

      Hi Jay,
      This document can help you further.
      It´s a “translation” from the old parameters to the new description and where to find them in the new menu.
      Kind regards,
      Anke
