    Sol-Ark and generator issue/ suggestions please!

    Your understanding is not exactly correct. When using the generator input the load is always powered by the generator. Additional, the inverter may charge the battery. In no cases does the inverter assist the generator to power the load while the generator is on. If the load on the generator...

    Sol-Ark - Inverter Monitoring

    Let's further simplify the system. Plug the SH-U11F USB connector directly into a laptop and run modpoll using the COM port. That way mbusd is not in the picture at all and you can confirm that your wiring is correct. Your test setup: modpoll loaded on a laptop The SH-U11F The cable you...

    Sol-Ark 12K with small generator

    Your STARTV must be more than 2V below your FloatV so yes, at least 2V. Then wait 40 seconds.

    Solark 12k bms recommendation?

    I used https://www.nuvationenergy.com/ They have a low voltage BMS that works pretty well and is UL listed. Assuming you are doing your own battery pack you might consider them. There is no comms between this BMS and the SolArk in my system. I run the SolArk in voltage mode and seperately...

    Was Sol-Ark 12K originally branded/sold as a 9K or changed before being sold as a 12K unit?

    What I have observed related to this is the high terminal voltage will cause the inverter to shutdown. If you can plot your grid voltage and then you observe that the shutdown last for exactly 5 minutes and the voltage is high at that time then this is likely your situation. When your inverter...

    Sol Ark 12k Off Grid with small generator - peak shaving

    Here are my observations on this topic. Support from SolArk customer service on this setup is thin at best. I have not found anyone there who can adequately describe how this was supposed to work or how to set it up. The manual has some hints but reads like the author did not not know what to...

    SolArk 12k Systems AC Setup

    I had the same issue with my SolArk 12K. My HP had about 92LRA so a little worse than your situation. I installed Hyper Sure Start Single Phase Soft Starter 230V (8-16 FLA) that I bought on EBay for $150 a few weeks back. Problem appears to be solved.

    Sol-Ark 12K with small generator

    Seems plausible that that is the reason for the delay but how did you come by this information? I am not using the generator start feature but the manual states that this is a relay contact closure between pins 7&8 of the terminal board CN1. There are no specifications given as to the maximum...

    Sol-Ark 12K with small generator

    An update on this topic for those interested. My MCU version is now 6211, I mention this because this version has a new check box on the Battery->Charge screen labeled "Force Gen" and it has different BasicSetup->Advanced screen layout with "Gen Limit Power" setting with no check box. These...

    What time of day best to charge battery bank

    Like Biasjo my batteries start charging once the PV starts to produce more than the house requires. I think it the best approach is it exercises the batteries the least as some days are cloudy and they then never charge. My theory is that less battery cycles is best. I have spent the day with...

    Sol-Ark 12K with small generator

    I agree that the waveform looks good. It is coming from the below generator unloaded. This is a $600 generator available on Amazon, no inverters in the generator.

    Basic internal block diagrams would be helpful for Sol-Ark

    This single line of the 12K is shown on a video up on youtube now. It's the only one I have seen. The same video shows the oneline of the upcoming 15K inverter which looks pretty cool. Not sure if this applies to both the 12K and the 12KOD. Its pretty helpful to understand the basics of what...

    Sol-Ark 12K with small generator

    I want to try an resurrect this thread as there does not seem to have been any resolution to the problem reported by the OP. I too have a small 4kW generator which I have wired to the "GEN" breaker. I have seen the grid icon change to a small generator when the inverter recognizes there is a...

    Basic internal block diagrams would be helpful for Sol-Ark

    I have the 12KOD. I can confirm that this unit has the ability to sense (and limit) generator power coming into the "GEN" breaker without the addition of any external CT's. When I purchased the unit I was told by SolArk support that this feature was new for the 12KOD and not on the 12K or 8K...

    Sol-Ark - Inverter Monitoring

    I hear you regarding the control freak part. It sounds like me. This is why I too was drawn to Home Assistant. The SolArk integration does not involve any data flow outside of your local network. It uses the configured Home Assistant database. In my case I use the default SQL database that...

    Sol-Ark 12K charge settings for Lifepo4 16S EVE 280AMP 48 volt battery

    I have a DIY Prismatic LiFePo4 620AHr pack connected to my SolArk 12K inverter. Not EVE but very similar construction. Battery type is set to "00", running in voltage mode, and absorption voltage set to 55V. Seem to be working well. You do have a good Non-Chinese BMS right?

    I have made my SolArk custom integration for Home Assistant available here for anyone interested. https://github.com/pbix/HA-solark-PV This is a HACS compliant integration. There are instructions on the main page of how to install it directly in HA. It uses Modbus directly. For now it...

    Sol-Ark - Inverter Monitoring

    I have invited you to collaborate on my custom integration. I wrote a little on the main page about how it work but in short I am using a USB<->RS485 converter and https://github.com/3cky/mbusd running on an old OpenWRT box. This is a direct Modbus interface to the inverter and does not require...

    Sol-Ark - Inverter Monitoring

    I have a custom integration for HA on github now. It has good functionality at this point when using TCP/IP. Should not be too hard to make it work with RTU, which is what I could use some help with. If you are interested in working on it let me know and I will give you access. Just send me...

    Sol-Ark - Inverter Monitoring

    I recommend that you plug your converter into your Windows box and use modpoll to test the hardware to make sure it is working before proceeding to software. Modpoll is a free utility you can get here. https://www.modbusdriver.com/modpoll.html I did not make any selection for "RTU vs RS485"...

    Sol-Ark - Inverter Monitoring

    I can confirm that the original post is correct and that the obtaining MODBUS data is straight forward if you have the documents linked to that post. In my system I am using the DSD TECH SH-U11F USB-RS485 converter. This is available from multiple sources for about $20. The reason I recommend...

    If you look at the screenshot I posted you can see in the middle there is a selection that allows uploading of a firmware image from your laptop to the Sol-Ark.

    It looks to me like you could update firmware without the internet by using the web interface of the Wifi Dongle. Below I show the screen I see. A procedure that might work would be to get the file from Sol-Ark tech support onto a laptop. Bring a router with you setup your inverter to...

    Sol-Ark system updates info?

    I have recently installed the 12K and got switched from the indoor to the outdoor model at the last minute so I became very interested in the differences. After investigation I found the following actual differences. 1) The outdoor model is outdoor rated. 2) The outdoor model has the Wifi and...

    Regarding: "What direction should I be installing the hall-effect current transformers? Where should I install them? Do I need them?" . Regarding if you need to install these or not depends on the mode of the inverter you intend to use. This is pretty well covered in the manual. If you have...
