I've been using various LLM's to build dashboards. Mostly ChatGPT but also Claude. I've been able to build complex dashboards without writing much code myself. It's an iterative process where the LLM won't get it right the first time but I tell it what's not right, or what the error message is...

The OEM for Seplos BMS v2 was Shanghai Energy Electronic Technology Co. The name was printed right on the BMS boards. I'm not positive that they also wrote the firmware but it seems likely. Their website says something about them being involved in "BMS research". It has been suggested that...

I’m getting two batteries installed in a couple weeks. I asked my installer for a photo of how he plans on combining the two batteries, because this has been bugging me, and he sent me this. What in the world is going on here? There are 6 wires. 2 pairs for two batteries plus a pair going to...

This should be easy but I’ll be damned if I’ve been able to find the answer by Googling. Take two batteries with only one set of terminals, so each needs to connect separately. I’ve read it’s not kosher to just attach both wires to the terminal posts in the inverter, so they need to be combined...

I’d be grateful for any corrections or suggestions to make the presentation more clear. It’s entirely possible that I still don’t understand these modes, but I’ll understand them eventually or die trying. I call the work modes simply Mode 1, Mode 2, and Mode 3. The names Deye gives them make my...

With a Deye system with microinverters there is a device called an MECD that’s used for logging. What I can’t figure out is where it gets info on consumption, import from, and export to the grid. My understanding is that this would normally come from CTs either connected to a smart energy meter...

I have two Seplos “Polo” 104-L 208Ah battery packs on the way. They use Gotion 104Ah cells in a 2P16S configuration for a total of 208Ah. I finally took a look at the datasheet for these cells just to see if there was anything interesting and indeed there is. The “Minimum limit for normal...

This is going to be a bit of a rant born of frustration at (1) poor documentation and (2) wrong information being posted by people who should know better (I’m looking at you Sunsynk). So, how does Smart Load REALLY work? First, a huge caveat. I don’t “know” from personal experimentation. This...

When I got Solar Assistant I registered my site. I verified that I could access my system and SA even remoted into my site to help me with a configuration issue. Other than that I accessed SA via the local IP address. I just left on a trip and I can’t access SA. Would remote access break if the...

I bought an Orange Pi with Solar Assistant about a month ago. It’s been working but today I can’t reach it. I’m away from home so I can’t physically check on it. If the WiFi rebooted and assigned a new IP address, would that be a problem? I never have an issue with Deye Cloud being able to...

I have a Deye inverter. I’m adding two no-name batteries with a Seplos-compatible BMS and an Orange Pi running Solar Assistant. My question boils down to whether I should use close loop communication between the inverter and battery and forego detailed monitoring of the battery with SA / Seplos...

I’ve been watching Off Grid Garage videos. His Victron system uses the terms absorption, float, and tail current. The Seplos BMS v3.0 manual does not use those terms at all. What are the equivalent terms for Seplos?

I’m in Thailand. Both the iPhone app and the web page are broken. Can’t log on in the app and the web page returns an error.

I have a 5.75 kW grid-tied system with no battery at the moment but the system is getting doubled to 11.5 kW with 20 kWh of battery in a couple of weeks. I’ll remain on-grid but want to put the whole main panel on the Load port of my Deye 10 kW inverter. 95% of our load is individual wall AC...

Something I’ve never seen discussed is what communication takes places when there’s closed loop communication between an inverter and a BMS. We’re left with setting a couple of voltages in the BMS for high and low “alarms” without understanding what happens at those voltages. Let’s say I set a...

I’m going to install two 10.24 kWh LVFU “powerwall” batteries. I’m in Thailand and it’s either LVFU or Pylontech, and I simply don’t have a good place for rack mount batteries so LVFU it is, I’ve managed to learn very little about this company. I’ve managed to learn what BMS they use but it’s...

I live in rural Rural Thailand and according to my inverter logs we experience quite a range of voltages with below 200 happening almost daily for an hour. Will adding battery and putting my main panel on the “backup” terminals of my Deye inverter have any effect on the voltage? Will the...

In Preferences Push notifications says “Push notifications not supported” on each of three devices, a Mac, an iPad, and an iPhone, all running Safari. Content blockers are disabled for this website. Is there maybe some setting related to cookies or something?

This is an idea ChatGPT came up with, but I can’t find any YouTube videos or forum posts to confirm that this will actually work. What I HAVE seen is posts from people using a dimmer switch to do this. Well, that’s what a voltage regulator is, a sort of dimmer switch. Let me start at the...

I have two Seplos 104-L 10.65 kWh “powerwall” batteries on order from Seplos, with v3.0 BMS. I have a Deye 10 kW hybrid inverter. I’ve read where a battery pack needs to be charged to 100% and discharged to 0% to calibrate SOC. How do I accomplish this, exactly? I’ve got quite a bit of solar and...

I just installed Solar Assistant yesterday. I have a Deye inverter and no battery yet. My first question is about what SA reports for load. While the solar was producing there was a blue line which tracked just below production. As the solar trailed off, load exceeded production but SA reported...

I finally have batteries. Yay. Initially no battery power was being used so I enabled time of use and that fixed that issue. I have very strong opinions on how I want to use my batteries and it has been quite frustrating that the Deye inverter has its own strong opinions. The setting for how...

I ordered two of these batteries from Seplos. They took about a month to ship to Thailand. They haven’t been installed yet but I’ve powered them on and looked at them with the Octopus BMS Lite Bluetooth app and BMS Studio. I just opened one up and installed an Enerkey active balancer. The...

I wanted SSH access to the Orange Pi. The version of SA I was running did not have that option so I was advised to install a new image on an SD card. This is when I learned the original installation was on internal eMMC flash memory. After the upgrade I had no history, so I booted back to the...

I have an Automatic Transfer Switch in a combiner box that isn’t being used. Meanwhile I’ve been trying to come up with an “inverter bypass” mechanism and I keep failing. I’m wondering if I can use the ATS set to manual mode as an inverter bypass? The wiring seems straightforward but I feel like...

What is the difference, if any, between the battery information display with “use inverter values” vs connected directly to the BMS? The inverter is Deye. The BMS will be Seplos v3.0. In other words, is there any benefit to a direct connection between the Raspberry Pi and the BMS vs getting...

What is the relationship between these 3 companies? They all sell nearly identical looking active balancers in 4A, 8A, 10A, and 15A versions.

I don’t have any battery at the moment. I have 20 kWh of batteries being installed in a couple of weeks. Selecting “Lithium” for Batt Mode is mutually exclusive with “Use Batt V” and “Use Batt %” so presumably % is used for other settings? What other battery settings apply when Batt Mode is...
