Solar Assistant integration of two batteries (two JK BMS)
I have a Growatt SPF5k inverter with two Lifepo4 batteries, each controlled by it''s own BMS (JK 100A). I there a way to connect both BMS''s to Solar Assistant? Currently it''s only one connected via RS485 dongle and the details aren''t accurate (-50%). Option would be to use inverter settings but I don''t want to lose the details provided by the BMS.

The new JK PM BMS is not yet supported by these solutions, my JK PB BMS is on 15.17 and I connect to it via Wifi using a HiFlying EW11 with a Virtual Serial port on the PC so I can connect and monitor the batteries anywhere on the local Lan. Once one of your solutions adds the JK PB BMS I will try them out.

JK inverter BMS CAN bus wiring | DIY Solar Power Forum
Typically the right two RJ45 jacks are used for battery to battery communications. The middle RJ12 jack is for Computer (or Solar Assistant) communications and the left RJ45 jacks (RS485 and CAN) are used for Master BMS to Inverter communications. The JK BMS manual counts pins on the double RJ45 jacks from left to right as pin 1 though pin 16.

What is the purpose of the GPS port on a JK BMS
Monitor JK BMS with Solar Assistant? @Nami It would be really good if you guys could provide a simple TTL/USB converter with the right connector for the BMS, so one can skip the RS-485 conversion. Or even just a connector with wires so one can attach a third party TTL/USB converter.

Can you recommend a BMS with Wi-Fi functionality?
I have a vacation home and I need to be be able to monitor/change the BMS settings remotely. I have a VPN setup on my router, so I have access to my local network.

Pulling the data into Home Assistant through the UART port connected to an ESP32 chip running ESPHome. The ESP chip sends all the data from the bms over Wifi. I have a new JK BMS coming in the mail - planning to set that up the same way this weekend with ESPHome. This one however I can connect via bluetooth instead of having to hard wire it.

6 FAQs about [Suriname solar assistant jk bms]
How do I connect a JK BMS to solarassistant?
Select one or more USB cables and click connect: Plug the RS485 USB cable into the SolarAssistant monitoring device. Once you click "connect" on the configuration page, you should see each BMS show up as a battery pack as shown below. One pack will be shown for each JK BMS connected in step 2 above. How to connect a JK BMS to SolarAssistant.
What RS485 cable do I need for a JK inverter BMS?
This guide is for the newer JK inverter BMS, also known as the JK PB BMS range. See our original JK BMS guide if you have their older original BMS. Use a Seplos RS485 BMS cable. If you are creating your own cable, note that RS485B on pin 1 and RS485A on pin 2.
How does solarassistant work?
When using the ports on the right, SolarAssistant will "listen in" on parallel communication going between the JK BMSs that are connected together. This is similar to how the official JK BMS software works. When using the port on the left, you need to configure the BMS to use the "000 - 4G-GPS" protocol using the official JK BMS software.
How accurate is solarassistant BMS?
Let SolarAssistant perform it's own state of charge (SoC) calculation by counting power flowing in and out of the battery. This is a good fallback option for anyone who can't get a real BMS reading. It's less accurate than a Victron BMS but much more accurate than the standard voltage based readings of an inverter.
How do I connect RS485 to my solarassistant monitoring device?
On the SolarAssistant configuration page, select the protocol below. Select one or more USB cables and click connect: Plug the RS485 USB cable into the SolarAssistant monitoring device. Once you click "connect" on the configuration page, you should see each BMS show up as a battery pack as shown below.
How do I configure a JK BMS to use 4g-gps?
When using the port on the left, you need to configure the BMS to use the "000 - 4G-GPS" protocol using the official JK BMS software. This is the protocol also used by the original JK BMS. On the SolarAssistant configuration page, select the "JK BMS" protocol as shown below. Select one or more USB cables and click connect:
