hello if off grid systems uses the method of grounding the ,,,,( solar panel chassis to inverter chassis to controller chassis and all to a metal rode and deep into ground )
wouldent this method will damage the system if the manufacture chooses the the - minus of the solar panel is grounded to the controller chassis and - minus of the battery is connected to the
chassis of the inverter
thus the minus terminal of the battery is conncted to the minus terminal of the solar panel and since the mppt is smps or some sort of smps
we now have violated the rule of isolation by connecting 2 grounds from different worlds together???????
this will create a local fireworks and lightening......and failed completely to protect from outer lightening and firworks simple as that
please add different suggestions to protect my new system that i am about to install from lightning????????
i wonder how this method protect from lightning the extra voltage will apear to the mppt controller and i cant see a way that it will get diverted to chassis ground???????
------------------------------------
system is 9 pcs 260watt 35voc
one 48 vdc pure since wave 6 kw inverter
master 100 amps mppt
4 pcs 200 amps 12 amper agm batteries
