Hi – I’m Lydian (Lydie for short), and my wife MaryKate (MK) and I have been discussing this dream for a decade and it’s finally happened. Our bodies are not compatible with Winter, so we’re going to follow the warmth, and we’re doing it in a solar powered Class-A motor-home.  And now we’ve started a business to help others do the same, hence SolaRVs is born.

My career is solar design and marketing at Mountain View Solar, for both grid-tied and off-grid systems, with years of experience designing battery based solar energy systems.  As an autistic woman, my special interest has been in electricity and energy systems since I was single-digit years old, so here I am!

We put 8 SolarWorld 320w 72-cell modules on the roof of the bus (those are the big ones 37.8″x78.46″ typically used on commercial arrays). They are tied to a Schneider 60-150 charge controller in 4 parallel strings of two, which feeds a 12kWh bank of lithium iron phosphate batteries at 48vdc (4x 250aH 12v units in series). This powers a Schneider XW6848 6.8kW inverter which has been integrated in such a way that the RV’s electrical systems remain essentially unmodified; the RV simply thinks it’s always plugged into the grid, even while going down the highway.

Another benefit of this large inverter is that I can limit the maximum power it pulls from grid, so even with a measly 15a 120v hookup, the system will pull from solar/batteries + grid as needed and never exceed what I tell it to, without any manual load management needed.  This also means that even at a campground with hookups, we can reduce the electricity charges.

Should there be bad weather for many days and we’re off-grid, I can turn the 8kW diesel gen on and charge the batteries in a couple of hours, then turn it off again, thus enjoying silence once again and barely using any diesel in the process.
