Yeah, I ended up doing it the way I suggested at first as I highly doubted the capacitors were on the outside of the breakers. Everything off. Connections made. Breakers on. Battery "turned on" (button) Power up Sol-Ark This worked, no damage, no trips.

Hardware Platform: Tigo CCA2 Firmware Version: 3.7.4-ct Mgate Version G8.59\rJul 6 2020\r16:51:51\rGW-H158.4.3S0.12\r I have to go to https://[cca ip address]/cgi-bin/shell if the unit has rebooted to re-enable ssh access. You're right. I used "which". It was in /usr/sbin You actually want...

I'll have to check mine when I get home. I'm sure that's the command I ran, but I can poke around a bit. I can also see if I can pull some version info. That was a suggestion from the German forum to ideally prevent unwanted firmware updates... but not sure if it actually will do that. I...

Yeah, we should potentially rename that thread since the answer was "No, we haven't figured out how to get the data from the TAP, but you CAN get it from the CCA" 😂

Thanks to everyone who helped! I did a test by turning off the service disconnect at night. The lights had the barest flicker, but nothing in the house noticed or turned off. After a few minutes, I turned the service disconnect back on, and shortly afterwards, the 15k connected back to the...

System has been up and running for less than a month, so I'm still dialing it in 😉 The 35% was based on a conservative estimate of running the house load through the night, and it almost isn't enough. It definitely won't be if the AC has to run much into the evening. Clearly I need more...

Mine was connected for days before I got control of it. DOING THE FOLLOWING MAY VOID YOUR WARRANTY First thing is to connect to http://[cca ip address]/cgi-bin/shell Username: Tigo Password: $olar I had to try several browsers before that worked. Then you should be able to ssh into it using...

According this article, the "Sol-Ark" optimizers are branded versions of the enteligent units: https://solarmagazine.com/2023/09/sol-ark-selects-enteligent-rsd-with-optimization-for-0900-80v/ And no, those don't appear to be available for sale, either because they need to be customized for the...

Sorry, just a bit bitter following a project originally announced in 2023(?) still not out, especially considering that they announced release dates, and then kept moving them. I'm all for only releasing a product when it is ready. But continuously shifting release dates sucks. I'm sure they...

Really? In fact, they seem to have actually disappeared from Sol-Ark's website. This link: Not longer appears on the "Products" page (but can be found on archive.org) And the URL of the "Learn More" link (https://www.sol-ark.com/optimizers/) just redirects to the main product page.

Great, thanks! I guess I should've just tested it to see what would happen without messing with anything.

I looked for this answer and was surprised I couldn't find it. I have a Sol-Ark 15k between my meter and main panel. I have 28kWh of batteries connected to it. I haven't yet switched to TOU billing, so I just have it configured to try and zero out grid use, and charge the batteries with any...

Oh, I thought only RS232 allowed write access. In that case, its just slightly more complicated from a wiring standpoint since I need to break out the CAN connection. I guess the only other thing I liked about the RS232 was that so long as SA worked, I didn't have to worry about big brother...

:rolleyes: Well *$(^#. I guess I need to swap from SA on RS232 to RS485 for a while just in case I ever want to use Sol-Ark's web portal.

Thanks! I saw similar code on the German forum. I tried to figure out what they were trimming and why they were padding the end with a bunch of zeros and gave up when it seemed like I couldn't pass the data directly into InfluxDB that was running inside HA. I did figure out the attributes...

oof. That was both easier and harder than I expected. I just installed InfluxDB into HA. This makes it easy to pass data from HA to InfluxDB, but makes it harder to get data directly into the InfluxDB instance. With the help of ChatGPT, I created a bash script to parse /mnt/ffs/data/daqs and...

I guess I could probably run the influxdb on the same Pi 4B as I am running HA? Otherwise, I have a Windows box that mostly just runs Plex. I have data from Solar Assistant piped into the HA Energy dashboard. (Someday I'll probably replace SA with direct monitoring of Sol-Ark using RS485). I...

Awesome. Let me know how you end up visualizing it in HA. How are you running influxdb?

I successfully followed the instructions on the phtovoltaikforum to gain access to the Tigo and its underlying file system. This lets you enable access to lots of extra data: Next, I need to figure out what to do with it... There are some examples on the forum to push it to InfluxDB, but I...

I just had a Tigo system installed last week. It is on my list of things to do to examine this RS485 stream, but I haven't gotten around to it yet. My plan was just to use an RS485<->USB adapter and log some of the data (should show up as a serial port). There are a few SW tools around that...

Just swap the plug.

Looks very nice. Mine will be here Monday. Though, I guess I should've ordered a set of PowerPro "parallel" cables to go between those and this.

Somehow the regulations let you park multiple 70+kWh NMC batteries in your garage, but not put 30kWh of LiFePO4 next to it.

Thanks @robby I guess I'm surprised that the capacitors are on the "battery" side of the Sol-Ark battery breaker (and I definitely want those connected to the battery before I turn the battery one so that it soft-starts into them... right?)

Can it be paralleled with the outdoor version? Connections looks the same, I assume the protocol is the same?

[Got buried on the General Discussion page but I wasn't sure if it was a "Battery" or "Inverter" question. I'll try here] Hi Everyone, I will be self-adding two PowerPro batteries to my new-ish Sol-Ark 15k system that currently has no batteries. I have enough professional experience with HV...

Hi Everyone, I will be self-adding two PowerPro batteries to my new-ish Sol-Ark 15k system that currently has no batteries. I have enough professional experience with HV DC batteries (200V+) to know it is important to get the order of operations right. Before connecting anything, I will set...

Apologies if I missed it, but I don't see in the product description what the V2 unit comes with in terms of DC output cables. I see the Degson connectors on the unit, but presumably it comes with cables too?

How did you tie the PowerPro to the tubing? Can you post a picture?

I currently debating batteries to pair with my upcoming Sol-Ark 15k. As much as I like the Pytes stuff, I'm struggling with the fact that the PowerPro seems to be almost double the energy density (volume, not weight) of the various Pytes enclosures.

This is awesome. I was also going to see what the comms between the TPA and CCA looked like.

My installer said his distributor could get them for my project this spring. So I told him to risk buy them immediately. That caused the availability to magically disappear. These appear to be vaporware despite the fact that they should just be a rebadged OEM part. My guess is that they are...

I'm not sure if I can post the link here, but this discussion over on powerforum.co.za has a lot of discussion on doing this (for Deye inverters, but hypothetically the RS485 is the same). Either you have to pipe the RS485 directly into whatever you are running HA on, or use an ESPHome. I'm...

My system will be installed this spring and I will attempt to go from the Sol-Ark straight to HA using RS485. I'll definitely post how it goes.

This still seems to be missing some details. I'm not super familiar with this chip, but from my brief reading, this is my understanding: The CH340 is a USB to UART (and RS232?) series of chips. It seems like in order to use the CH340 with RS232 levels, you still need to use an RS232 driver like...
