![]() There isn’t just one brand that makes the top of the line for every RV solar component and this setup below will allow you to customize your solar setup to have the top of the line RV solar panels, RV batteries, and inverter. If you want the best RV solar system for full-time RVing and boondocking, look no further. Unfortunately, lithium batteries are still very expensive ($800+ for good ones), but if you are interested we have rated our 5 Best RV Batteries from AGM to lithium. ![]() That is why the RV solar calculator shows that you need 2X as many lead-acid batteries to get the same amount of usable power. The major downside to any lead acid battery is that you can only use 50% of the battery storage without damaging the battery. Renogy batteries are tested for the various conditions that RVs go through, and the ~$200 price point for 100Ah makes these a great entry-level battery. If you can afford the upgrade, lithium batteries definitely have major advantages. The best RV batteries for someone on a budget are Renogy lead acid batteries. MPPT charge controllers are much more efficient than their PWM counterparts, and this upgrade will save you from having to get an extra solar panel.Īfter choosing your solar panels and charge controller, next are your batteries. Renogy makes a few solar panel kit options, but you will want to make sure you go with one that has an MPPT charge controller. You can use this RV solar calculator if you aren’t sure how many solar panels you need for your RV. You can always add more solar panels to these kits if you want. I really like this Renogy 400 watt solar panel kit because it comes with four high-quality 100 watt solar panels, an MPPT charge controller, and all of the wiring and mounting hardware that you need to get started. Setting up this system requires no prior electrical experience as the components are all plug-and-play. This simple and inexpensive RV solar setup will keep you powered up while you explore nature off the grid. Modified sine wave inverters can damage your appliances, and the extra hundred bucks is worth protecting your MacBook. There are many low-cost options out there, but make sure you get a pure sine wave inverter. If you need to keep your laptop charged or you want to power up the TV to watch your team’s game, you can add a simple inverter like this 1200 watt Pure Sine Wave Inverter for around $200. While the setup above will be able to keep your batteries charged and DC appliances running, you won’t be able to run your AC appliances (anything that plugs into a normal wall outlet) without an inverter. If you plan to RV in the cold, add a 2nd battery. Using your furnace on a cold night will draw 40-50 Ah from your battery bank, which would take a single lead acid battery down to zero. While the furnace uses propane to create heat, it also uses a fan to circulate the heat. Pro tip- A significant power draw that you might not think of is your furnace fan.
