To connect DC to inverter i used 3d printer and made several DC glands designed by crasbe so thank you. Links are here: https://openinverter.org/forum/viewtopic.php?t=3563
I printed one black gland and one violet – its what i had in PETG – to differentiate DC+ and DC-.
I got a couple O rings 18mm by 3mm thickness to seal the opening. It is quite a tight squeeze because O rings are medium hardness and i cant get any softer version.
I connected 35mm2 cables in those glands.
I connected motor cables, yes i luckily got good motor cables with sealed covers.
On the bottom there are two secondary DC connectors that lead to the heater and charger. I like MC4 connectors so i made those connections removable and connected shield to the casing. Every part will be connected to another by grounding 6mm2 cables.
