We have modified the RV with energy saving systems. Going solar for our RV was a great move. We watch our 32" tv (led) at night, use lights (LEDs). brew coffee in the morning and our battery bank is recharged by 2pm in the afternoon. We have two 165 watt solar panels with a 2500 watt inverter and four 6-volt deep cycle batteries. Great for our dry camping adventures which gives us flexibility in our camping styles.
