Thanks, I've taken a peek at Solcast! Lol, I'm a Scot who moved to Oz, I think I found Jevjev's part 1, of a series of 1, he has a similar accent to me, I think he's from Edinburgh.

Hi, I'm trying to decipher this document I found online, can someone please help me, I can only see two CAN IDs... CAN ID 0x35C a table with just one byte CAN ID 0x359 a table with four bytes Then there are seven tables with no CAN ID: 6 bytes 4 bytes 6 bytes 8 bytes 8 bytes 8 bytes 8 bytes...

Wow, thanks for sharing!

Wow, an EV with V2X sounds cool, I'm still rocking a 2012 Prius V 😂

Thanks, yeah, its a tricky trade off but one thing I can do is sell down to 75% SoC after 14:00 as no matter what that will get me to the next day. Like yesterday I was fully charged by 14:00, exported solar the rest of the day, woke up to 55% SoC so my batteries are on track to be charged by...

The batteries all have an internal BMS (with no comms interface), they trip on: Over current : 41A Over Temperature : 65°C Under Temperature : -40°C Over Voltage : 57.5 V Under Voltage : 41.5 V Tripping is not ideal but it basically makes it impossible for user error to damage the battery?

Thanks, I do have node-red enabled to manage solar export, that's been running flawlessly for over a month.

Thanks, my system is super convoluted, on the MPPs if the batteries go below 44v the MPPs switch to grid mode (they have an AC in & AC out connection). I also have a Latronics ACTS transfer switch to protect against the MPPs failing. My always wanting to be in battery mode has more to do with...

Thanks. Yeah, I think Australia might be a bit ahead of the curve with arbitrage. So I'm in NSW on Amber, we currently have a 26.58c/kwh FiT rebate / import penalty (EA959) between 14:00-20:00 every day. So if there isn't much sun in the morning then quite a lot of people top up from the grid...

Thanks, I have LTO batteries (Zenaji Aeon) so I'm not super concerned about cycles, although they were over twice the price of LFP. Yeah, weather & solar forecasting being part of the logic is probably a bridge too far. I'm thinking the first check should be for price spikes or a negative...

Thanks My hardware is working. I'm already on 30 minute billing. Currently, I just sell battery manually over modbus on my GoodWe SBP G2. This question is about the logic of exporting battery.

Hi, Is anyone doing DIY grid arbitrage with 30 minute (or more frequent) wholesale price windows (I'm with Amber in NSW, Australia)? I'm interested in automation using node-red and was hoping to get some ideas on the best battery charge/discharge logic. There are so many variables I'm...

Thanks, I have a ESP32-EVB-EA-IND that has a CAN transceiver and interface so that should be the hardware covered. The programming is above my comfort level though, any ideas on how I could get this done, anyone had any luck with getting coding done on a platform like Fiverr? MQTT subscribe...

This is amazing...Thank you, thank you, thank you! I have a SmartShunt that already publishes its values through MQTT (ICC Solar does this on an RPi4 that has the VEDirect USB attached). So I have the values from the shunt on a mosquitto server, can I use this to feed my GoodWe SBP inverter...

For batteries without a BMS with comms, is this able to create a "fake" Canbus BMS to send battery info (perhaps supplied from a SmartShunt via MQTT) to a (GoodWe) inverter?
