Inverter/charger or Inverter & Charger each has some benefits. Separate also has some benefits. Which is better? Which would I choose? Inverters and chargers are actually two different items. Some manufacturers have built chargers into inverters and these units, depending on their design have some advantages over separate units. However, some inverter/charger combinations are not […]

RV Solar Series: 12 volts or 24 volts is a question the doesn’t get asked very often. The fact is that there are advantages to both configurations. Before we consider the advantages of each, we need some understanding of how multiple batteries work with each other. Volts and Amps math Battery banks can be assembled

RV Solar Series: Inverters change Direct Current (battery power) to Alternating Current (house power) so that you can use house appliances inside your RV. Some RVs don’t have any inverters and some RVs have huge inverters. Some, (usually older) RVs don’t even have a battery (this is very rare). My RV has a small inverter,

This is my Lithium/Lead Acid Final Analysis where the determination isn’t necessarily all data-driven. Live style makes a big difference in the end result conclusion on the Lead/Lithium debate is going to happen. One of the biggest problems with lead-acid is that they don’t like to give up electricity without a fight. Tell this to

RV Solar Series: For a solar-charged RV battery, battery choice is critical to living with an RV solar battery charger. Battery design determines success or failure. The question comes down to Lead or Lithium batteries. Originally published March 2019 Updated June 2020 and March 2024 The first question that the RV Solar Series needs to address

RV Solar Series: Limit of the design. Everything has limits. The limits I have are daily sunshine is required and battery size and type. Even though I met all the design goals, I need to have the sunshine every day. In the summertime, I will have much longer daylight periods to charge the battery. The efficiency

RV Solar Series: How to use the Generator with Solar. The sun doesn’t shine every day so you can’t expect that solar is going to be your only power supply. My solar coupled with a bigger battery bank of the right kind of batteries could bridge multiple cloudy days and return to a full charge

RV Solar Series: Analysis & Conclusions is the summary to the testing page. The testing page has more meat and this page details what happened. I also offer theories as to what could have happened with different decisions. We are very happy with the results and look forward to more off-grid camping that will be

RV Solar Series: Testing the System is not such an easy task and involves camping at various times a year without outside electricity. Testing in mid-winter will come at some later time. Testing in March is a good balance between summer and winter conditions. How did I get these numbers? The combination of our battery

We have gathered data on electricity used in our RV and have compiled a solar report to analyze the actual results. We still have issues of understanding what is going on, but overall we are thrilled. Yesterday was the true test and we did really well. Data to follow. Starting last spring we monitored battery

RV Solar Series: Installation of the panels is the easiest part aspect of installing a solar battery charger on your RV. My panels are installed on a fiberglass roof — your roofing materials and desires will change your installation techniques. Running wires from the panels to the location near the battery is the hardest part

RV Solar Series: How to Design a Just – Right – System. A just-right size, not too small, not too costly. Sounds like Goldilocks. Just right. Start with simple and work to more complex.   Start with a battery.   Add to that a positive and negative wire that leads to a small solar collector. Connect

RV Solar Series: How much solar did we need? My answer was 600-700 watts of solar installed flat, (700 installed) to recharge our battery and live daily. Given six hours of sunshine, (winter) assuming the batteries were not overly discharged we should be good. Part of the assumption was that you can’t always count on

RV Solar Series: How we Store Electricity is a key consideration, almost all RVs have some kind of central battery. We wish we had the best battery. Nearly all RV manufacturers put the lowest cost battery in an RV, just to give it the minimum. Thankfully when we purchased our RV, the original battery had

RV Solar Series: Quit wasting electricity. Turn it off, make it better. Measure to know where it goes. Change your location. Turn it off One of the things I first encountered before measuring my energy use was that I had no way to completely disconnect the battery from loads. There was a switch in the

Electricity – 101 RV Solar Series: Understanding Electricity is not optional but is not a concern in everyday modern life. What is electricity? Before you make a change to your RV electric system, you better understand at least the very basics of electricity. When you turn on a flashlight, you create a circuit.  The components

Measure to know RV Solar Series: How to know what just-right means. How to know what just-right means in an RV solar system design. The answer is you have to measure to know what you need. How do you measure to determine what your needs are? This is a key step. Lots of folks put

RV Solar Series: Introduction “Boon-docking” or “dry-camping” is an RV style that refers to camping in an RV without the attachment of electrical, water, and sewer hookups.  We bring our own generator to make electricity, sometimes campground rules restrict generator operation hours. The most restrictive generator hours we encountered were at Death Valley National Park
