Question.... I have a off grid system. But want to use grid charging when available.. it has a AC input and an on-board charger. How can I set it up to charge from grid? I'm having trouble figuring it out. View attachment 212629View attachment 212630
Ok good to know I didn't think to check that. Also the system I have is with an old firmware. Is it needed to be updated or can I use it as is. I know several months back signature solar was selling kits for updating the systemYou would also need to check the charger source priority to make sure that OSO is not selected for solar only.

You should be able to scroll through the display screen option to see this.Is there a way to check current input.
Check charging settings to verify that you have it set to charge from the grid input.I had it running for several hours and looks like the SOC indicator didn't move.
You can keep it plugged in for as long as you want.Should I keep it plugged in overnight?
This indicates a problem in your wiring.Ok so the problem with the AC imput is that it does not like the GFI outlet. It will trip it all the time.
Here is 3 photos of the wiring I did. The system is stand alone not tied into anything. The far left 20amp is main inverter input the rest out to loadsThis indicates a problem in your wiring.
I would guess that there's a second N/G bond.
Not according to your post.The system is stand alone not tied into anything.

I see. But the inverter is not on at this stage only the imput to charge battery. I belive the PV imput works the same way, dosent it? I don't know if there is something important that I'm missing here. Can you please explain what and how the braker can be wired to ha e a correct flow without blowing anything out. If you want picks on all the wires I can post them.Not according to your post.
When you have AC input, it provides the N/G bond.
In your pictures, the neutrals and grounds are bonded together.
This is a second N/G bond. You can only have one N/G bond.
Two creates a parallel path between the bonds. And neutral current will flow on the grounding system. This is called a ground fault. The GFCI is seeing this and tripping to save anyone from getting shocked.
When powered by AC input , the unit is in bypass mode.But the inverter is not on at this stage only the imput to charge battery.
I'm in the process to get it updated. Will that fix the issue of using AC wall plugs imput to charge and using inverter output for loads?Also, if the 6500 is on the latest firmware of 79.71, you should have a setting 42 which can enable/disable the neutral-ground bond.

It won't solve the issue of your neutrals and grounds together in your loads panel. That must be corrected by you.I'm in the process to get it updated. Will that fix the issue of using AC wall plugs imput to charge and using inverter output for loads?
Hold up. I've been thinking about this.. why should it matter on the AC imput side of the inverter if I have ground and neutral connected together on the output side. There is no bipas it's just imput to charge battery.It won't solve the issue of your neutrals and grounds together in your loads panel. That must be corrected by you.
You can't have input without bypass.Hold up. I've been thinking about this.. why should it matter on the AC imput side of the inverter if I have ground and neutral connected together on the output side. There is no bipas it's just imput to charge battery.
Sorry took so long to respond, had stuff to do... So your saying if I rewire the box and put all the grounds on a separate busbar in the panel this will solve the bypass fault with N/G bond. This will give me the option of running AC input for charge and not creating 2 n/g in the system? Also if I use PV input as charge, does this apply the same way with the bond? I was under the impression that if it is a primary panel the n/g can be together because it is not used a a sub panel. So if i only run PV that should not have any issues. But if I need to use grid ac to charge i must have ground separate because it now makes the panel as subpanel.You can't have input without bypass.
I have the update cables and software that I got last year. is that the most reascent software or is there something out that is newr?It would enable you to verify that only one neutral-ground bond is present in the system.
