I've got an old MP deployment that needs fixing/replacement (it's on the other side of the planet so I don't know what's wrong with it, local resources suspect a power issue or a lightning strike). Regardless, I'd like to upgrade to something more modern. This is literally in a jungle with just Solar/batteries to power it (not full time), so looking for a power efficient outdoor ready unit that can mesh, and take unregulated input voltages. Doesn't need any phone support. What's the best hardware kit for this role? I'm familiar with Ubiquiti equipment, and we don't have very high speed internet at all, so don't really need super-high performance. I'm considering just deploying a Unifi Mesh, since it's a pretty small deployment, but I'm concerned about how the mesh would work long term without a controller to arrange the mesh between the individual units.
