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

Your welcome. But don't go around saying I am nice or helpful. You will ruin my reputation. Just tell me to go F myself like everyone else does.

No matter how much you push the envelope, it’ll still be stationery.

I have downsized to an 800 Watt inverter. I will only use it for more than the tv or stereo on rare, very short occasions.
Cheers

A much better choice than your original for your battery capacity. Seems many think a bigger inverter will give them more power when in reality the batteries are where power is stored and available according to battery type.

I can't thank you enough.
Thanks for all your help and advice.

The check is in the mail Sunking!
Could I push my luck and ask one more question?
Is it ok for me to use a generator and battery charger to bring my batteries back up? I have an intelligent battery charger which is safe for AGM batteries. Can I just attach the charger while everything else (charge controller, inverter and 12 Volt panel) is attached?

Absolutely.

[CanadianCabinSolar]

Yeah that is a $500 answer huh?

OK you owe me big time. Ask anyone here, I do not do this type of thing.
For the MRBF fuse to CC = 30 amp using # 8 AWG
For the MRBF to Fuse Panel = 200 Amp using no less than 2 AWG

Should I downsize my inverter?

I would. I noticed it earlier but just ignored it. You want to run the smallest inverter you possible can. Try to add up any likely devices to be on at the same time. Say that number is 400 watts. Multiply that number by 1.5. So in this example 600 watts.

Another good approach is to use two inverters. One small for the every day stuff, and a larger one for those rare occasions you need it. Keep the large one turned off until needed.

Should I downsize my inverter?

Might be more efficient. Save a bit on wiring too.

[FloridaSun]

I was worried about that, but the inverter will generally only be used to power a 19 inch LED TV and media player. I just wanted to have more power if I needed it on the rare occasion.

Rare very short occasion.

[CanadianCabinSolar]

fuses aside.. I'm surprised you haven't said anything about using a 1750W inverter with 200Ah battery...... Seems a bit too much inverter to me.

You also have a problem with your wire gauge from Fuse Panel to Inverter Input. A 1750 watt 12 volt inverter will take 145 amps at full power. That will require #4 AWG. Personally I would not connect the inverter to the fuse block. I would connect both positive and negative directly to the battery post using a second single battery MRBF Battery fuse (150 amp) which is not shown in the drawing. I do not think you can find a 150 amp blade fuse for the fuse panel.

Thanks for all your advice.
I have ordered the two terminal fuse blocks and three fuses in the sizes you specified ( man, I love amazon ).

Thanks again.
