Not sure how many of these are out there in an off-grid setting. But my 45 panel setup was updated to FW ver: 520-00082-r01-v04.40.01 on 09FEB2024 which has completely SOLVED the issue I was having for several years with regard to power factor issues. My setup is a dual Sol-Ark 12k and 45...

I have dual Sol-Ark 12Ks with 4 strings of IQ7 microinverters in an AC coupled install. Once the battery reaches a certain voltage, the sol-arks begin ramping up the frequency to curtail IQ7 output. Using the right Enphase configuration and the IQ7s will adjust linearly based on frequency. It...

You have to connect to each inverter. However, a recent firmware change to the Sol-Arks now follow the modbus index for each unit. Before, each unit responded to address 1 (for both master and slave), Now, master is 1 and slave is 2, but each still has its own serial connection to your host...

SOLD.

Sounds good. PM me and we can exchange info.

Yeah. I also worked with Franklin. It's a solid design, I just went a different direction.

That's funny. I just updated the price. I had it on here for awhile and then thought someone else was going to take it... never happened and it has been collecting dust (the box has) ever since. It should probably go to a good home.

Back up for grabs! Still in same condition as first post.

Of the script? It just prints out the data to the terminal. For the VenusOS: Note: This is NOT currently using modbus data, but rather gets limited info using Shelly EM devices.

Thanks for the excellent pointers solardad! Hardware success using the Victron VenusOS on an RPi 3 with the JBtek USB to RS485 Converter Adapter ch340T. Here is a sample python script that uses the pymodbus library to pull values from a single 12K inverter (I have a parallel system and will be...

2x SMA Sunny Island 6048 Inverters. Local pickup in North Texas, $2000 each.

@GXMnow, I've been working on using the SMA Sunny Islands with 14kw Enphase for an offgrid install. Without an external grid, the SMAs don't like to keep synced beyond about 3kw and then go haywire. I've tried about a dozen enphase grid profiles, but there is something about them that the SMA...
