Need help with Magnum Inverter/Charger set-up

I changed Batteries and need to program for 750 AH, the factory default is 450.
Reading the setup instructions, I go from 02 low battery cut-out, to battery type; 04. My setup skips the AH setup feature: 03.
Anyone have this problem?
Besides me....?
Thanks.

Do you have the ME-RC50? On mine if I push the "meter" button first (instead of the "setup" button) then scroll I get to the AH setting (which is 05 under meter). I don't have the battery meter hooked up so not sure if does me any good. Maybe we have different model Remotes or something. I generally change that charge rate when I'm on generator to keep the gen from running full tilt.

Same model as mine. both legs are wired to individual sub panels. The RC50 is the remote panel model I have.

Good luck with the toppers! Those are on my short list somewhere

Ozz on my Magnum the F03 setting is for AC input. This is where I can set how many AMPs I want to take from the shore power. I do not think there is a setting for AH on the Magnum, On your Solar charger which I believe is a Midnite Classic 150 you can set the AH.

Dave, I am feeding the main panel, I want to be able to run anything I want within the Inverting limits, didn't really see the need for a sub- panel
The toppers are not too bad to install, but with just
My wife and I doing it, we take it slow and safe. I just installed exterior pull down black shades.
The walls will not hold any screws, so I had to pull the window treatments from inside and through-bolt all of them.. A big job.

Thanks, my instruction book has the setup instructions for it, but maybe my system does not. How would you put your battery bank size in? I know it needs that info.. It is a Inverter/Charger, it would need that.
Yes, the Midnite Classic setup is next, I haven't even had that energized yet, installed it then summer hit and I ran service all summer, retired the HVAC company and now fixing the Montana so we can hit the road.

I am feeding my main breaker panel also. No sub panel which is simple and works great. Today I was helping a friend with his inverter system which was installed in Quartzsite last winter. I was able to trace his problem to his battery posts on the inverter. They nut on the ground connection was not only loose, but the nut was completely off the stud. This install was done by a professional installer..

Larry, the job was a rush job to keep the profit high, as it always does, the quality of work suffers. The old check-double check goes out the window unfortunately. Nice of you yo help your buddy, glad you found the issue.. And glad it was simple to fix.
