Little Guy Max, lots of solar and a large battery array
Hi! I'm interested in setting up an LG Max to be suitable for comfortable off-grid living for 3 seasons. One of the things that this would entail is expanding the solar array on the roof to whatever maximum wattage I can fit there. The other is increasing the battery bank to at least 4000wh (and probably more). Once I have that, I should be able to install a Dometic 12V high-efficiency AC unit and run most of the appliances (minus heat / hot water) off solar.
I'm new to the RV game, so I'm still getting my bearings. I wouldn't want to heavily modify the LG Max and I'd like to avoid drilling the exterior as much as possible. Does Xtreme Outdoors provide customizations for LG Max so these changes could be added during the build? Or would they at least be able to install a waterproof connector for solar and then I'd be able to add my own batteries / BMS / charger ?
Please someone correct me if I'm wrong here, but I think Xtreme Outdoors doesn't have a option for added solar. At least I didn't see one. I have seen owners add a new solar panel with a little more capacity but not to the extent you are asking for. Personally, I believe you will have to build this off the unit and then tie in afterward to your grid. Similar to using a generator. The unit currently does not have the space or capacity you're wanting, especially for batteries. If you're not moving the unit constantly, this is fairly easy. If you want it mobile, well that's a different situation. The current solar on these things is only designed to keep the single battery or a `second in series charged for your lights.
Our off grid use is for a few weeks at most and we employ a 4500w generator for air conditioning and heat if needed. Generally off grid, we use the unit as a rolling tent for sleeping and shelter. We're in Texas, so our cold and hot is relative..... Pretty sure that doesn't help much, but thought I would add my 2cents - taxes.....
If someone has other options or you come up with a cool solution, I would surely like to hear about them. There are a lot of innovative owners and ideas out there.
Thanks for your reply! I think I've figured out the least-invasive approach to trying this out. LGMax has a 150lbs 2" receiver on the back. I could get a waterproof container mounted on the back there, where I'd store a Ecoflow Delta Pro unit. I could glue solar panel mounting hardware onto the roof and a conduit for the wires to run to the Ecoflow. Then I can simply plug in the shore power plug into the RV outlet of the Ecoflow. This is far from efficient - I'll be going DC -> AC -> DC for things like lights, but it requires no drilling or cutting of the body.
Really not a bad solution to be honest. Good luck and let us know how it goes including pictures.
