35w - 16w = 136w ?

screenshot-2022-07-29-191752.pngHi, trying to workout the logic of dc loads , So my 2 mppt controllers are generating only 35 watts now it is starting to go dark , my shunt says that 16 watts is being to the battery which means that 19 watts is being used somewhere , so why 136 watts ?

Have you got a wiring diagram? Chances are something is bypassing the shunt.

I've checked that I haven't made a mistake , Battery to the shunt , the other end of the shunt to a busbar with the mppt chargers and inverter , So all loads have to go do through the shunt .
