The generator cranking draw & my hydraulic levelers are the reason I kept my AGM battery connected to the 12v side in my RV.

If you are running an absorption style fridge on electric, then this is a typical load (at least on mine). As already stated, it will drain your desired battery bank over night.

Here's my n=1 experience with dicor and bolts: it will eventually harden and crack from expansion & contraction as well as vibration around fasteners. I assume that when visible cracks are seen, they were first hairline micro-cracks for quite some time. Believe me, water will find its way into...

Test mineral spirits on your roof surface. It may not remove hardened dicor, but it will eventually remove soft stuff.

Given the minimal amount of sealant you used on the brackets, I would just unscrew them from the roof, then seal and remount in the same holes. I can see potential water intrusion paths around the bolt heads in your pics.

One consideration for most solar charge controls is that the input voltage to the SCC/MPPT from the solar has to be ~5V higher than the scc to begin charging. So for a 48v battery, the solar would need to be whatever the battery state is (example 51.2V + ~ 5V = 56.2V from the solar array)...

Is your converter & 12v DC loads/fuse panel an all-in-one? If so, remove the Converter AC and feed the DC fuse panel with the 12v from a 24v-12v step down. My converter in my rig was separate, so I just removed it and replaced it with a 24v/12V 70A Victron Orion. Works like a charm...

I recently installed six 450W (82" x 41") on my 5th wheel. I used commercial roof racking (Tamarack) to mount them with 6 connection points per panel (3 rails). I could have gone with twelve 200W panels in the same area, but chose the larger ones because it reduced the roof penetrations and...

On the ground would be the winner. If that was an option, there is no way I would consider roof mounting them.

I'm sure A1 doesn't give the exact location of their warehouses until you order is to prevent potential customers from contacting the locations and arranging the purchase through the local solar companies. At least that's what I've concluded in the Tampa, FL area where there are dozens, if not...

I bought 6 - 450 W ZNShine panels from A1 Solar. I chose those because they were available locally, and were the highest wattage that fit the available space on my RV. They seems decent for the money given they are chinese built. A1 Solar contracts with local solar distributors to handle the...

Have you done an energy audit to see how long that 15KWH will last? Do you have enough open roof area without obstructions to mount enough solar to replenish the 15KWH of batteries in your expected time frame? If not, are you supplementing with a generator? Do you have a rough diagram of what...

See this post. It's a diagram from Victron... https://diysolarforum.com/threads/50-amp-otg-victron-battleborn-set-up-on-a-45-foot-toy-hauler.58819/post-736384

I haven't crimped anything larger than 1/0 with mine. I used FTZ Powerlugs & I didn' have to deviate from the listed tables for the die settings & each lug required 2 crimps next to each other. The crimper got to max pressure and then kind of eased as the dies touched with a slight overlap at...

Are you using FTZ brand Powerlugs or some other brand? Different brand lugs might require an adjustment. The lug "table" on the handle is specifically for their FTZ lug designs. My crimper shows 4/0 = A/A for a Powerlug & A/B for their flaired lugs.
