AC coupling with solark is possible but only is you have a very big battery, otherwise you do not have where to store that extra energy. Personally I am not going to use microinverters ever under any circumstrance. Cant stand them.

Solark 15 K puts put 15 k continous.

I've been eyeing a Sol-Ark for a few years. Is your inverter new enough that you can add another in parallel or add microinverters on the switched input/output of you wanted to?




I do not want to parallel my inverter. I want to by a 15k when I have some money and keep this one for backup.

there is anyway to modify the code to use the USB cable to communicate with the computer?

I started my first system with junk like this about 14 years ago

I then moved to SMA 4000TL-US 4KW grid Tie inverter. Very efficient but not hybrid. SMA like Nokia did not want to change with times and was left behind.

Looks awesome! I use nexion display too - but a small one.
To keep it clean, for the main screen I just display the motor direction, speed and vehicle state - (drive, charge, error) and error pop-ups. Ex. motor temp H (warm)/yellow, HH (hot)/red. Then I have separate details screen for all my ...

Hybrid inverters are the way to go. now they are cheap.
About 8 years ago when I got my first hybrid inverter i paid a lot of money. Now you can get a 12k inverter with 2585$

If anybody has an idea of what else should be on the main screen please let me know. There is still some space.

Would be nice is a real programmer would work on this.

I have posted all screen files here:

Can mappings work for the inverter. at least first 2 and 4th. To test the other 3 and 5 I need to drive the car.
Now even if the BMS does not have the correct voltage for the battery, I am taking the battery voltage from the inverter (udc) and is showing the correct value of 369V.

I will post all ...

If you can send me a screenshot with which parts to replace and a link with the parts I have to buy I can try. I tried before on 2 boards with no success.

So..... I was doing the CAN mappings for the motor and inverter. I saved the mappings and turned off the car and turned it back on.

The screen was not showing the SOC anymore and the voltage was 309V instead of 369V.
2nd BMS was blinking slow and when I looked it is MUXSHORT...

I am going to try to finish the CAN mapings for the motor. inverter, battery temperature temperature and RPM, next 2 days and then I will post the files.


I was trying for a new look in Photoshop but that is going to take a while.

I have to thank @PetersonOctavius for starting me and helping me on this project. I will open another separate thread to post the current files in case anybody wants to use them. they work for nextion 5" and 7" screens. both have a 800x480 displays. mine is the 7" version.

Can I install the latest 0.26.R on my boards? I have a combination of v 2.1, v2.2 and v2.3 boards

@ johu, can I use the BMS to get the state of charge of the battery and bypass the ISA shunt?

Do you have any 3.7v batteries to go over 4v? Even some small 26500 batteries would work.

The requests are still going, now from China also. I will need to find a solution that automatically blocks an entire /16 subnet as soon as it detects too many requests from that same subnet. That is what I currently do manually.

The forum runs on a hired server somewhere in Germany, so can't play with the hardware. I assume the PFSense Firewall could be installed on it?

I am sure Iit can Be installed on a VM but not sure whatbis involved.

If that server is at home you can install a PFsense firewall - Free software and then you can have lists added to known bad servers or IPs.

You just need a computer with 2 NIC cards

these are some of my lists.
