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.

        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.

    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.

      Hi Barry,
      Sorry, but your battery is not approved for a Sunny Island system. For safety reasons we don´t support the configuration of unauthorized systems. You need to ask your installer/the one who sold you this battery. Otherwise please check the list of approved batteries here. Thanks for your understanding.

    I have Sunny Island 8.0H with a Honda EU70IS Generator on current control
    Mode i can’t run the generator over the maximum amp 20 amp ( I can’t draw 20 amp from the generator and power from battery at some time if need the system will just blackout of 5sec, it very hard to get the sunny island to run well with generator, the Sunny Island can easily run all the loads by itself 6000w+ and Sunny Boy is also working fine. So why can the Sunny Island, Sunny Boy and Generator all work at same time and take 5kw from Generator 2-3kw Sunny Boy and 1-3kw from Sunny Island battery if need like the Victron inverter Quattro (power assist) as if I have the generator on I can’t run the induction cooker, But it runs fine with generator off. On the Sunny Island and Sunny Boy

    Reverse power to generator is off as are still waiting for a answer from Honda
    Reactive power compensation is also off, would it help if it was on?

    Also I has lost the generator icon in the main screen

      Hi Clinton,
      Normally it should not be a problem to use the generator together with the Sunny Island (SI) and with the Sunny Boy (SB). All the power should be added.
      Do you have a SI 8.0H-11? Then please set parameter 234.03 GnCurNom to 20A. It should limit the current. If it does not work at all, please set the parameter 234.15 GnCtlMod to CurFrq.

      If you have a SI 8.0H-12 you should set in the parameters: Generator > Nominal current > 20A, and under “operation” > Type of current limitation > frequency dependent current limitation.
      To have a bit more margin, you can also set 18A.
      I hope, that helps.

      Kind regards,

      Hi Cristian,

      Within one Cluster it is not possible to mix SI-11 and SI-12. An update of the SI-11 to a SI-12 is also not possible. Only complete cluster can be mixed, e.g. MC-Box 12 with 3 x Cluster (9 x SI-12) with 1 Cluster (3 x SI-11).

    I have a hybrid system with two Sunny Boys and a Sunny Island. After a power failure the battery will charge up to 93% and then reduce COC over a number of days to the low 80% despite the constant trickle charge. Why is this happening? Why is the COC not staying in the 90 ‘s.

    Hi,
    running 3-phase SI8.0-12 now with f/w 1.4.0.R
    Configuration for system is increased self-consumption and backup. I am using an Enwitec automatic transfer switch. Enwitec batfuse and Tesvolt TS25 48v battery system.

    When testing backup-functionality (disconnecting mains), the entire system shut down (house goes dark) for ~5 secs before SI’s got online and powered the house. When I reconnected the grid, the external grid was not brought online and this was in events: Ext grid disconnect due to undesired island grid at phase L1
    (405). I suppose since f/w 1.3 the switchover should have been more or less seamless (0-20ms or so) ?

    I checked and re-checked all connections, but can’t find anything wrong. Any ideas for troubleshooting? Faulty/bad shielded signal cables from master? Bad mains connection?

    Dear sir,

    I want to buy SunnyBoy 6, which is has the following specs:
    Maximum PV array power: 9000 Wp
    Maximum input voltage: 600 V
    MPP voltage range: 25 V to 500 V
    Rated input voltage: 365V

    I am confused by above numbers. I am planning 2 strings of PV panels, one for each MPPT input. So if I connect my panels in series for a single string and with Vpm adding up, the max number should be 600V, or 500V or 365V per string?

    Thanks a lot!

      Dear Sendy,

      Umpp (Inverter feeds in) must be between 210V and 500V. It is not allowed to exceed 600V. Therefore you have to pay attention to the coldest expected module temperature at none working Sunny Boy.

      The easiest way to make it sure is to use our planning tool Sunny design.

    Dear SMA support,

    I have two Sunny Boy 4000TL-21s and it was running fine (Still is) with 7.2 Kw modules
    Living in South Africa power is cut regularly – Poer supplier calls it “Load Shedding” – just so you know the terms we use.
    I had to add a Sunny Island 8.0H ver 12 to let the PV Modules keep producing power when the grid is out.

    I commissioned my Sunny Island with Backup Box and Home Manger 2.0 on Friday afternoon and with the first “load shedding” Friday, batteries depleted to 50%.

    I have now tried everything in the web interface (169.254.12.3) -> to change parameters so the batteries will charge from 50% to 100 using either the grid or Solar.

    I am using Sealed Gel batteries so the Battery type is set to FLV.

    Input is ONLTY Grid or PV (from the two SynnyBoys)

    Could you please provide me with the critical the critical setting I should set my SunnyIsland via the web interface to ensure the batteries charge back to 100%.
    Currently hanging at 50%, so I need to charge them before next power outage scheduled for Monday 16h00.

      Hi Imo,

      Yes, the SI 8.0H-11 is with the FW 3.1 Li-ion battery compatible and the port for the CAN communication between SI and battery is the Comsyncin or the comsyncout. Both ports are bridge inside the inverter, so if you have a single device, the open entrance that it´s not use, should be close with a 8ohm resistance. This resistance comes with the SI device in the accessories.

      You can find the most recent firmware updates here.

    Hello SMA!

    My location is the United States. I currently have a grid tied system of 19.2kWDC panels connected to two SunnyBoy 6000-US and one Sunny Boy 4000-US. Each of these Sunny Boys currently has a bluetooth piggyback card installed.
    I’d like to install two of the Sunny Island 6048-US in a split phase configuration with an approved battery to give me off-grid power in the event the grid goes down. Does the Sunny Island control the older Sunny Boys via frequency shifting only, or do I need to purchase an SMA RS485 piggyback card for each inverter, replacing the bluetooth piggyback cards? Is there additional SMA hardware I’d need for this type of install?
