hello, i have searched on this, there is a lot of information to sort through but have not found an answer to my understanding; i appreciate feedback.
the questions build on themselves so i can hopefully understand the impact of each component on the grounding needs.
baseline scenario
my system is 2 lithium batteries in parallel for 200A bank, on (+) side from battery, i have a main shut off, then distribution block. On (-) side i have the vitron shunt, then distribution block. Fuse box is connected to both distribution block and all consumers have 2 wires each.
If there was nothing else in this system (BB charger, inverter) , would i need a ground?
add bb charger to above
add bb1260 sterling 60a charger, positive wire with 80a fuse to charger, then + and - negative wires to the distribution blocks?
If i did not need ground in baseline scenario, do i need one now? if so, can i simply run a cable from (-) distribution block to chassis and be done?
add inverter to above
add progressive dynamics pd1620 2000w inverter to + and - power distribution blocks.
If i did not need ground in baseline or with bb charger scenario, do i need one now? if so, can i simply run a cable from (-) distribution block to chassis and be done?
twist: introducing ac power here by adding ac in from shore power. the inverter has internal switch so it will use either dc battery power or ac power to feed the ac outlets. Does that change anything in terms of grounding meaning if i didn't need a ground at all so far do i need one because of the ac in?
