Earth Grounding Questions (and many more) for a small off-grid system.

[CanadianCabinSolar]

For now all I am going to say is for a 12 volt system, it is not required to ground the system. The panel by code needs to be earthed, but not the system.

Thanks for the reply Sunking. If that's all you are going to say for now, are you going to say more later?
At www.backwoodshome.com, Jeffrey Yago, P.E., CEM discusses a small 12Volt system like mine and states " You also need to add a separate bare-copper wire from this same ground rod to the grounding bus bar inside the main circuit breaker panel."
I also read something somewhere about the fuses in a DC system not functioning correctly without an earth ground. Not correct?

And the inverter will be connected to the battery with battery cables. # 4 ( I think),

Hello,

My main question is about the earth grounding for my small off-grid 12V system. But I will, if I may, describe my setup in some detail and ask for any advice that you can give this noob.

Please tell me about anything that seems unsafe, stupid or just won't work!

Thanks in advance.

This off grid system will be near Sturgeon Falls, Ontario, Canada and will be only be used from late May to late October.

1 Kyocera 140 Watt Solar Panel ( Model # KD140GX-LPU ) which will be facing true south at 35 degrees, grounded with #8 bare copper wire to a ground rod driven next to the

cabin and connected with MC4 connectors to

1 Morningstar ProStar 30 Charge Controller ( Model # B002MQWXB4 ) which will be connected to

2 12V Eliminator Renewable Energy 100 AH Deep Cycle, sealed AGM (Absorbed Glass Mat) lead acid batteries ( Canadian Tire Model # 11-1879-8 ) connected in parallel which will be

connected to :

(1) An Eliminator 1750 Watt Mobile Power Inverter (Canadian Tire Model # 11-1845-8 ) which will be used to power a 19 inch LED TV and I-omega Media Player or home stereo for 3 - 4

hours on most days.

(2) A Blue Sea Systems 5026 ST Blade Fuse Block ( Model # B001P6FTHC ) - will be connected with # 8 wire to the batteries negative and positive and will have a IMC 100 AMP fuse on

the positive line.

The Blade Fuse Block will have a separate #8 bare copper wire connected between the ground rod and negative bus. Are these 2 ground wires all that my system requires? Or do I need

to run another # 8 bare copper wire to the negative connection on the inverter?

The Blade Fuse Block will power 9 separate circuits:

6 are for RV 12 Volt lights with LED replacements for all the bulbs - 5 double fixtures with 921 bulbs and 1 single fixture with an 1156 bulb. - all 3 AMP Fuses

1 is for a SHURflo ( Model # 2088-422-444 ) 12 Volt 7.0 Amp Water Pump to feed a propane heated shower with rain water. - 7.5 Amp Fuse

1 is for a permanent mount USB Dual Port Charger. - 3 AMP Fuse

1 is for a permanent mount Cigarette Lighter Socket. - 3 AMP Fuse

So there it is, my wee solar system. Please help me out with any tips you can give me and feel free to question me about any info I omitted.

Thanks Again

Doug
