No Internet - Remote Solar Monitoring with cheapest Android Tablet wirelessly to Solar-Assistant

Many of our customers ask us for a completely off-grid solution with Monitoring, this is how we did it.
We bought a cheap Android Tablet, and got remote monitoring and logging of our Solar System without internet access, perfect for RVs Cabins and just about anything else. You can do the exact same thing on your phone, or old throw away phone.
We also show how to heat water with all the excess Solar once batteries are fully charged
