This off grid solar power information system is perfect for your Van or RV. It gives you a complete view of your Van’s power consumption and solar panel generation, it also predicts how long your batteries are going to last for and how much power is being generated by your solar panels. That’s one less thing to worry about!A quick look at the indicator lights tells you when your solar panels are charging your batteries, when they are generating more power than you are using as well as when your batteries are almost flat. An alarm sounds if your batteries are then further discharged to the point where they are at risk of being damaged.The LCD provides you with detailed information on how much power your batteries have stored, how much is being used, how much is being generated by your solar panels and how long your batteries will last for. The circuit is really simple to assemble and doesn’t require much soldering, it can be assembled on a breadboard if you are not confident soldering. You will need to know the basics of programming an Arduino, if you haven’t done this before – here is a useful guide to getting started with Arduino. You will also need to know roughly how to connect an LCD screen to an Arduino.
