Is anyone running the 0605 release in parallel? I'm having an issue with the slave unit reporting twice its load. The Main unit is correctly reporting its load based on the current its drawing from the battery. On the slave unit, however, it is reporting twice its load. What this does is...

Me too, lol. I've updated firmwares so many times, but I was extremely careful updating my new unit. :)

I noticed the screen shot shows APP where the instruction sheet says BOOT. Could this be an issue?

Well after 1Y and 163D, one of my MR8k blew up. I wasn't sure if I was going to post about it until I solved the issue. I have over 15MW thru these inverters. I'm not very hopeful that I'll receive support from my distributor (GSL) but I did contact them. I had two inverters in parallel...

Yes, I updated firmware.

I believe there was a different work around, but if you put the file on the root of your C: drive, it may fix that, worth a try.

The version i tested with the broken parallel feature was the 12/12/2022 release. I keep going back to 8/3/2022 version.

There was a bug in one version of the firmware that even when set to parallel, they still only maxed at 8k. I'm running the very first parallel firmware version that has other bugs, but has been rock solid for over a year. One day I plan to upgrade to the latest version.

I am running DIY batteries with no comm to the inverter. I had to set my battery capacity to 1000Ah in order to maximize the charge current to the batteries. It seems the inverter was limiting power when I had it set to 280Ah. It might be worth a try to temporarily change battery settings to...

Did you try to install with PV and RSD switch off?

Yeah, that is what i was referring to the _1.24. (y)

In the solarman interface, there is 'inverter' and 'logger' under the 'devices' tab. Click on logger tab, then your logger for the parameters. I don't know what the latest is, but 1.24 is when I noticed the expanded information.

I may have missed some posts above, I apologize. But have you verified you have the latest firmware on your wifi dongle? I posted earlier in this thread that there is more data available with the newer firmware, but I'm not sure if it would affect the accuracy of those numbers. I do know that...

Looks like I stopped getting notifications via the bell icon (I disabled emails), and missed a bunch of these MR posts. Thanks again to @fromport for keeping the firmware database.

As @fromport said, there is some calibration that can be done via modbus. The 2v thing really messed things up because I have solar strings into both inverters. Once that inverter 'thought' the target voltage was reached, it would stop producing power via solar. Once I sent an new calibration...

I was the one having that 8kw overload error. Please let us know if the low 3/4 has been solved with the generator version. My older MR parallel firmware works great, but I have low 3/4. I read a while ago that MR was going to release a firmware update to allow for only 1 set of CTs, but I...

Solar assistant *should* be working, although I haven't tried it. Home Assistant works perfectly for me. It's still early in the morning, but here are some stats: Notice I'm still on old firmware which has the PV3/4 low production bug.

What is your charge protect voltage set to? Make sure you increase the charge protection voltage higher than your desired charge voltage for Lead-Acid if NOT using communication. In lead-acid this is either 59.5v or 60.0v max depending on firmware. If you are using communication from your (4)...

Push IN the RSD button.

Which position is your RSD switch?

I never knew that was an option, neat!

Same here. I am only doing basic. I have not tried anything beyond basics as @fromport mentioned. Knock on wood, my two work perfectly and the only downtime is from when I was messing with (crap) firmware. I am not using them "properly" since I am off-grid and have to use Lead-Acid battery...

You may be able to disable the reboot every morning if it is the internal test.

Its on a 30A GFCI breaker. If only I could figure out how to rewire to it to charge the batteries :ROFLMAO: None. I also charge my Tesla at 30A for hrs on end with no issues. I admit there were plenty of firmware issues and I had to do a LOT of digging to get the modbus protocol working with...

I am running 2 lifts and a 120v air compressor off-grid with my 8k unit. My pumps have been wired for 240 and it is no issue. If your motor can be rewired to 240, you should have no problem. I have since installed a 2nd unit and more batteries but 1 unit ran the shop just fine. Inverters are...

I'm running 2 in parallel for about a year now. I am off-grid. Are you using BMS/Lithium battery or are you set to Lead-Acid? Does the inverter batt voltage show the same voltage your physically measure at the terminals? What is your actual measured PV input voltage?

I don't really care who creates/updates firmware, tbh. I almost feel like the community could really add some good feedback if it was a more transparent process, however. Firmware number is useless, and there is no official change log that I've found. Also, some newer versions with generator...

Sure has! In the beginning, there were some days I accidentally charged the Tesla too far, or left aux heat cranked thru the night and the batteries hit low voltage cut off, which as you can guess, shuts everything down. Luckily, once sun comes up the inverters turn on from PV power, turn on...

I purchased from GSL, but it seems all vendors are hit or miss. You might be better off with signature solar, but I would just go for price, tbh. I have 2 of these units in parallel running fully off grid in split phase, similar to what you are proposing. I also have 13kW of PV, and ~44kWh of...

Firmware is updated via the USB port of the inverter using the 'stream' program that is included in most of the firmware zip files. You should be able to get the firmware from your distributor, or some have been linked in this thread.

Sent you a PM

I'm off grid but it would be nice if they did that. It is an option for start stop generator Control.

I believe that is the 8/3 firmware and generator was 8/23

There are generator settings in the firmware since 8/23 release, it is menu item 16.

There is a note that the Slave won't output power until it 'sees' the master. On the old firmware, I can turn each inverter on or off at random and the load never drops, it doesn't seem to matter. I never switch off the breakers to the panel. I'm not sure if it matters, but I haven't had an...
