Got the upgraded solar/inverter/battery setup installed and got first trip out with it.
This is some serious hardware but did not take up much more of my basement storage. The new charger/inverter replaced the dedicated refrigerator inverter and moved the solar charger down close to the batteries where it should be. There is a breaker which cannot see in this pic and disconnect so can shutoff solar and solar charger properly to make changing batteries, etc. easy and safe. Can see the new "battery box" that extends into the recessed storage area in the basement which is an extension of the stock lower battery tray. I could easily extend this for two more of the big oversized batteries I have. Used 2 gauge wire for the main solar drop and the 2/0 gauge from charger/inverter to batteries and between batteries. Both were high quality flexible welding cable which works great compared to others for solar:
Here is the battery bay with two on top and two on bottom now. The front jacks needed to be lifted one notch so that the hydraulic lines cleared the big battery cables. Can see the Battery Monitoring Kit and Catastrophe fuse added at the top:
Here is how the lower battery tray was modified on bottom and in the end was a fairly simple fab job all things considered since it just extends off original bracket and no additional work for ventilation:
All six of the 160W panels on the roof now. Have room for a couple more if ever needed and extra capacity with the 80A solar controller. THey even seemed to help a little keeping the rig cool soaking up that sun and another layer to keeping the roof from so much heat soak but perhaps I am just dreaming this
Really liking the Magnum Advanced Remote. It has way more features than I will use but gives full control of the entire system. I now have a convenient way to turn off the inverter and can see how many amps each device I turn on draws from the battery bank. Has lots of options to protect the inverter from low voltages and general monitoring of things like net amps or amp hours. Really cool and useful stuff!
At a cost of less than 10% of what people typically pay for this rig it is well worth it for my application. It got me from an almost useless rig to true glamping for my application so is more than just an electric refrigerator thing! Watching the monitor and seeing 50amps coming in from solar this weekend and charging over 100amps on generator is nice. Batteries never dropped below 75% overnight even without a generator run before bed. Nice to be able to get coffee early in the morning without waking up the rest of our group with generator noise and even turn on the microwave. I will mention the big High Pointe microwave we have pulls a ton so that even our 3100 external generator struggled with it and the battery bank/3000W inverter also does not like it at night without solar supporting it and other small loads (lights/TV) as it causes a really big voltage drop initially which trips my low limit I currently have set to help protect the inverter from low voltage (good thing my battery monitor kit revealed what was happening).
Props to D&R Family RV in Phoenix who are true solar electric specialists and spent hours with me designing the system, listening to my input also, and doing a great job on the install.
