Progress.

Power button fitted, it glows blue when power is on. And XT-60 connector for solar panel ready.

Used some plexiglass to make braket for cells. That worked better than expected. Need to clean those edges. Installed fan, easy. Hole not so easy. Got no right tools so needs cleaning. Something like this. Next: cut 4mm aluminium pieces for + & - , drill holes and make them threaded...

Happy holidays! I ordered very simple beginner 3D-printer. It has not arrived yet, but i have found lot´s of things i can use it for. Car audio projects, battery and solar stuff and so forth. I did had couple of courses of cad designing at school so not that much of punch in the face. And those...

Thank you for help. I did order those caps. But problem is really not inverter. Skip BMS and all works just fine. Here is video of BMS connected. I used H4 bulb 55/60W @ 14.40V. BMS triggers for no reason. I ordered Hakadi BMS for replacement. I have balancer on batteries and it is doing great...

8 series 10 parallel will make 16-32V 100Ah battery. You need one BMS: 8S 24V 200A will work great. Got my 3D-printer. Work has started:
