Regardless of the UPS, you said you use a "wall wart" 5V AC power adapter. You didn't have any risk of 32V to begin with. This thread has been discussed problems people could have in general, but don't apply to your original question/scenario.

I see they mention the USB TTL adapter, but I'm not sure how to wire it into the JK BMS. https://solar-assistant.io/help/battery/jk-bms

I'm intrigued by the solution you have. As far as i know DB9 ports isn't usually used as a power source. Which DB9 pins did you get power from on the Sol-Ark and what is the voltage?

You don't need the beta, just an update to the latest stable version. It allows changing date/time. See "Added ability to set system time manually. Useful for users without internet": https://solar-assistant.io/help/updates/changelog Just to confirm: you need to connect the PI to your iPhone...

I believe the RS485 can be used to read the inverter, as long as your manual describes it as a parallel or expansion port instead of the BMS port. It should probably work with PV Keeper and/or SolarAssistant. https://www.ginverter.com/list-20-2.html

As far as I know all easun inverters are voltronic inverters, but looking at the easun downloads page I see watchpower is listed under most inverters, but not all of them: http://easunpower.cn/Download/ If watchpower doesn't work with your inverter, then I doubt solar assistant, solpiplog...

When you run watchpower on your laptop, is it able to read your inverter via the serial RS232 cable and adapter you have?

Good point, with bluetooth each JBD should be readable individually. What software or utilities do you use to read the JBDs via bluetooth? Is it the mobile app, or is there something you are running from a computer or Raspberry PI?

With a protocol such as modbus each device has an address. The read command always contains the address to read from so even if all the devices receive the message, only one will respond. If you look at the JBD read command it doesn't contain a way to specify from which device you want to...

Looks like latest beta can now edit Growatt inverter settings: https://solar-assistant.io/help/updates/changelog

If your inverter is reading your battery via the RS485 then yes a splitter won't work for you. Even if the inverter is just set to read from RS485 and you connect SolarAssistant to the port it can't read from it. That leaves you with only one monitoring port, the WiFi/RS232 port. Some of the...

@lekeola Which inverter are you monitoring with it?

I think there are many now. Some of these links could be helpful: https://diysolarforum.com/threads/sol-ark-needs-a-serious-change.27144/page-12#post-349029 https://solar-assistant.io/explore/solark#hero https://solar-assistant.io/help/configuration/sunsynk

I would start by ensuring you are on the latest release. The changelog for the latest version lists fixes for both LV/LVX inverters and Solar first mode, both seem like what you are describing: https://solar-assistant.io/help/updates/changelog

Just found this, not sure if it works. Pin 4 - 9. https://alena-energy.com/wp-content/uploads/datasheet/MAC-50-60KTL3-X-LV/MAC-50-60KTL3-LV-User-Manual.pdf

Did you end up finding the answer here? I'm also interested.

Yes I still use the inverter CAN port to connect the battery BMS. This is the solar assistant settings pages: If you want to use both the WiFi dongle with Powerview and SolarAssistant at the same time, then you need to connect solar assistant via the RS485 port instead of the WiFi/RS232...

A really easy way to monitor your Sol-Ark inverter is with solar assistant. I noticed other users on this forum using it, then I installed on a Sol-Ark installation a few weeks ago. It's excellent, gives you Grafana charts, allows inverter setting changes, home assistant integration, etc...

Do you keep a laptop permanently plugged into the inverter to collect statistics over time with PVKeeper? Or do you go and plug it in when you want to view the inverter, then it has history data?

If you already run solar assistant then getting your data into home assistant is easy: https://solar-assistant.io/help/integration/home-assistant

Not completely... I had a pretty legendary Home Assistant inverter monitoring setup with Grafana. For remote access I couldn't do port forwarding due to ISP limitations. I tried the official remote access for Home Assistant called nabu casa which worked great but after trial it's $5 per month. I...

Hi Guys, Sol-Ark is basically exactly the same inverter as Deye and SunSynk, its just different branding/marketing. You can get real time monitoring with this product: https://solar-assistant.io/ I doubt that Sol-Ark has modbus over TCP because I haven't seen that option in solar assistant...

Hi Joe, what exactly do you mean with "have to make SD card bootable before unpacking Solar assist file"? Did it first not boot? and how did you fix it

I'm also a long time Home Assistant user. I had my inverter, battery, relays, etc. integrated and solar forecasting via SolCast, to predict when my batteries will be fully charged to switch inverter mode: I then discovered SolarAssistant and basically abandoned my whole HomeAssistant setup...

Hi Guys SolarAssistant is by far the best monitoring I have found for MPP Solar inverters. Unfortunately not free but pretty cheap: https://solar-assistant.io/explore/mpp-solar https://diysolarforum.com/threads/solar-assistant-data-logger.21099/

It asks for username/password. If something doesn't look right in the app I would just email them. Found them pretty responsive in the past

There are a few other options available. Not sure if will work for Heltec comms:

Hi Darren, a friend of mine emailed them and they offered a trial license. Then we tried it again for another setup and they gave another trial license. I suggest you mail them, the email is at the bottom of their website.

I have 2x PIP-5048MG with 3x Pylontech US3000. I'm very happy with my setup but if I bought today it would be one of the newer ones like the PIP-MAX or one that has 0ms transfer time with lithium BMS connection support.

I used ICC previously and converted to solar assistant. Quite an improvement... https://solar-assistant.io/

Another option: https://solar-assistant.io/

Posting what solar assistant looks like as an alternative to ICC for interest sake: http://solar-assistant.io/

I've used many different solar monitoring solutions including ICC. I would recommend solar assistant. Works great from android/iphone too. https://solar-assistant.io/

Similar experience for me with solar assistant: https://solar-assistant.io

Solar assistant also supports victron BMV with similar power grid/battery switching as ICC: https://solar-assistant.io/help/power-management/axpert
