Solis owners

    Just a quick question for any Solis hybrid owners is there any way to schedule charging from grid on a certain day?

    With the smart plan I'm on there is free electricity from 9-5 on a Sunday. I have been charging batteries from grid with time scheduling charging set from 9am-5pm and discharging from 5pm-9am but need to manually do this at present every Sunday as can't seem to find a way of selecting it to only charge from grid on certain day. Am I missing this or just not available with Solis inverters?

    You will have to do it manually sadly. you cant pick a day to charge. Now thats as far as I know, send Solis a email they might have another option.

  • Registered Users Posts: 2,789 ✭✭✭ irishchris

    Cheers, figured that was the case as couldn't find the option but thought best ask in case I was missing something obvious somewhere in menus.

    just fyi, you may have to do a full manual restart of the inverter, battery etc., I had to do that when I enabled & set the Time of Use timings

    As already mentioned you cannot do it this through normal Solis controls but it is possible. You can do this through modbus. This would require some extra hardware but nothing too expensive.

    I think you can set up daily schedules as long as you have the latest firmware installed.

    Can't think when it became available something like FW 0033 or 0034.

    That is interesting. Sorry for staying offtopic but does anyone has a flash stick and firmware?

    My supplier had tried to flash it a while ago and had no luck. I am just wondering if it worked for anyone else as I am stuck on 0022.

    After you sure on that as got this reply from Solis support this morning "Currently this logic isn't built in. I don't believe we have plans for this either".

    They have been wrong in the past though. Would you mind checking your Solis to see if allows specific daily scheduling. Mine allows three charge and discharge times but not selectable days.

    Just got installed running SW version 360026. I cant see in Advanced setting anything that looks like scheduling.

    I'm on 350022. Wonder what the changelog between 35 and 36 is.

  • Registered Users Posts: 1,294 ✭✭✭ SD_DRACULA

    I can't even find this in the settings, so maybe just doesn't exist?

    Hi, just had a solid Inverter installed. Is there a crib sheet to set the attached battery to charge from the mains at night.

  • Registered Users Posts: 3 tiffer

  • Registered Users Posts: 7,749 ✭✭✭ Ha Long Bay

    From Solis support.

    First step is to make sure you Set Storage mode to self-use mode 

    Advanced Setting->Storage Energy Set->Storage Mode Select->Self Use->ON 

    Enable charge from grid function

    Advanced Setting->Storage Energy Set->Storage Mode Select->Self Use-> Charge from grid->Allow

    Set time charging to ON

    Advanced Setting->Storage Energy Set->Storage Mode Select->Self Use-> Time of Use->RUN

    Select a charging time to set force charging the battery for the period selected

    Advanced Setting->Storage Energy Set->Storage Mode Select->Self Use-> Time of Use->Charging time

    Sorry left out that the pin to get to advanced settings on the inverter is 0010

    What is the max number of PV panels on each string for a Solis 3.6kW Hybrid Dual MPPT (RHI-3.6K-48ES-5G)

  • Registered Users Posts: 1,488 ✭✭✭ bullit_dodger

    Looking at the specs for the inverter....

    Solis RHI-3.6K-48ES-5G 3.6kW Hybrid Solar Inverter

    If you have any technical queries about this product or wish to report any issues with the information on this page then please use the Contact Form to contact us.

    Supplier Part No: SOL-3.6K-RHI-48ES-5G-DC

    Weight: 17 kg

    Rated Power: 3,600 W

    Min PPT Voltage: 90 V

    Max PPT Voltage: 520 V

    DC Startup Voltage: 120 V

    DC Shutdown Voltage: 90 V

    Max Input Voltage: 600 V

    Max DC Power: 7,000 W

    Max AC Power: 3,600 W

    So (like many other inverters) the max input voltage is 600Volts. The voltage for most panels, and this DOES vary so you need to check your own panels spec, is about 40-45v, so you can fit 12 panels (12x45=540v) on a string. 13 at a "push", but I wouldn't advise it for a variety of reasons which I won't go into here.

    Your pushing the inverter a bit though (watt wise) if you have 12 panels on one string....and probably another 6-8 on the other string?

    I recently had a Solis inverter installed by an installer. S5-EH1P6K-L I checked my meter a couple of days after installation and it had registered a shocking 428 units in just over 48 hours. It seems the calibration is way out of whack on the RS485 and is telling the meter we are consuming power we are not. The installer has gone very quiet so I've had a look at the Advanced Information panel myself.

    The alarms list shows an MET_SLT-FAIL alarm.

    Does anybody know what the meaning of this alarm is?

    My second question relates to the alarms list on a brand new Solis. Is it normal for there to be Alarms in the alarm list prior to the supposed installation date of the Unit?

    I would expect that to be clean however mine has entries for June and April this year. It includes another MET_SLT-FAIL alarm from last April. Note: it was installed last week. i.e September.

    I find this surprising! There are two possible explanations that I can think of. Either the manufacturer put it on a test bed in April and I'm seeing alarms from that. However its that's the case it would appear they shipped with this MET_SLF-FAIL fault. The other is that the unit has been installed previously and developed the same fault previously.

    Neither conclusion is very palatable. ANy insights would be welcome.
