Hello, , after i bought my third gtil1000 i noticed that there are a few modifications, The one that is affecting the sunScreen print is the fact that a few relays are added to switch the mains on and off from the powerstage. These relais are powered of 12 volt, and you guessed it, that 12v is coming via the sunScreen print if you mount that. As a result the lithium battery will be empty before you know it. My workaround is to feed the relay modification with the 12v BEFORE it enters the sunScreen print. The other modification they applied was the change from transistors to fets to switch the fans, so no need to change transistors. Hope this info helps.

Currently my single phase SUN1000GTL2 inverter imports about 10-20W from the grid while limiting. What can I expect from the Split CT with two phases while limiting?

After install i noticed inverter status (ion) may not be accurate. While in remote mode and limit mode set to power (limtm=2), The inverter responds well to plim commands, but I noticed (at times) that ion will show 0 or not generating. Also the inverter does not respond when I publish to topic 2ms/SB/0/c/ion with 0 while the inverter is generating power. Also is it possible to configure the lcd state remotely (ex: 2ms/SB/0/c/lcd)? And I just noticed via the web interface the "Show Commands" feature for MQTT pub topics, nice touch and super useful! And at some point it will be nice to be able to configure the MQTT message rate, 1 Hz could be useful.
