Solar and Power
MPPT charge controller
Maximum Power Point Tracking is a type of solar charge controller. It adjusts the incoming voltage to harvest more energy from your panels, which helps most in cold or low light conditions.
MPPT and PWM controllers comparedPWM charge controller
Pulse Width Modulation is a simpler, lower cost solar charge controller. It works well for small systems where panel voltage stays close to battery voltage.
where PWM falls behind MPPTSolar charge controller
A device that sits between your solar panels and batteries. It regulates the charge so the batteries fill safely without overcharging.
the charge controller guideLithium battery (LiFePO4)
Lithium iron phosphate is a battery chemistry common in RVs. It is lighter than lead acid, lasts for more charge cycles, and lets you use more of its rated capacity.
the RV battery guideAGM battery
Absorbent Glass Mat is a sealed lead acid battery. It costs less up front than lithium but weighs more and offers less usable capacity.
RV battery types comparedDepth of discharge
How much of a battery's capacity you use before recharging. Lithium batteries tolerate a much deeper discharge than lead acid without harm.
how to size a battery bankState of charge
The current charge level of a battery, shown as a percentage of its full capacity.
how battery capacity is measuredAmp hours (Ah)
A measure of battery capacity. It describes how many amps a battery can deliver over one hour.
our RV power calculatorsWatt hours (Wh)
A measure of energy equal to volts multiplied by amp hours. It lets you compare batteries of different voltages on equal terms.
our RV power calculatorsPeak sun hours
The number of hours per day when sunlight is strong enough to produce full rated panel output. It varies by location and season.
the system sizing guideMonocrystalline panel
A solar panel made from single crystal silicon. It is more efficient per square foot than polycrystalline, which suits limited RV roof space.
the best RV solar panelsInverter
A device that converts battery DC power into the AC power used by household outlets and appliances.
the solar power guidePure sine wave inverter
An inverter that produces clean AC power similar to the grid. It is safer for sensitive electronics than a modified sine wave unit.
where an inverter sits in a solar buildConverter
A device that changes shore power or generator AC into DC. It runs your RV systems and charges the house batteries while you are plugged in.
how shore power and solar feed the same bankDC to DC charger
A charger that uses your engine alternator to safely charge the house batteries, including lithium, while you drive.
how house batteries charge while drivingShore power
Plugging your RV into an external AC source, such as a campground pedestal or a home outlet.
how solar covers the nights without a hookupSeries and parallel wiring
Two ways to connect solar panels or batteries. Series raises voltage, parallel raises current, and the choice affects which charge controller you need.
how wiring choice changes the controllerBattery management system (BMS)
An electronic circuit built into most lithium batteries. It monitors cell voltage and temperature and disconnects the battery to prevent damage from overcharging, over discharging, or extreme heat.
the best lithium batteries comparedPolycrystalline panel
A solar panel with silicon cells made from multiple crystal fragments melted together, which gives a blue speckled look. It generally costs less than a monocrystalline panel but converts sunlight at a slightly lower rate per square foot.
the best RV solar panelsModified sine wave inverter
An inverter that converts battery DC power into an approximate AC waveform with visible steps rather than a smooth curve. It costs less than a pure sine wave inverter but can cause humming or poor performance in sensitive electronics.
what a solar system has to powerSolar generator (portable power station)
A unit that combines a battery, inverter, and charge controller in one sealed box. It charges from solar panels, shore power, or a vehicle outlet and needs no separate wiring.
whether RV solar is worth itSolar suitcase (portable solar panel)
A portable, foldable solar panel set in a hinged case with a stand. You set it up outside the RV and angle it toward the sun, which can harvest more energy than a flat roof mounted panel of the same size.
flexible and rigid panels comparedBattery monitor (shunt)
A display paired with a shunt that measures the current flowing in and out of a battery bank. It shows real time state of charge, voltage, and remaining amp hours so you can track power use.
the battery types a shunt watchesRV Rentals
Class A motorhome
The largest motorhome, built on a bus or heavy truck chassis. It offers the most living space and usually the highest nightly rental rates.
RV classes explainedClass B RV (campervan)
A van based camper and the smallest motorized RV. It is easy to drive and park, which makes it popular with solo travelers and couples.
a campervan against the bigger classesClass C motorhome
A mid size motorhome with a cab over bunk, built on a van or truck chassis. It is a popular family rental.
how a Class C sits between A and BTravel trailer
A towable RV that connects to a standard ball hitch. You tow it behind a truck or SUV and unhitch it at camp.
towables against drivable RVsFifth wheel
A large towable RV that connects to a special hitch mounted in the bed of a pickup truck.
where a fifth wheel fits among the classesPeer to peer RV rental
A marketplace model where private RV owners rent their vehicles directly to travelers, similar to home sharing.
the rental marketplaces comparedDelivery RV rental
An option where the owner delivers and sets up the RV at your campsite or destination, so you never have to drive it.
RV rentals near youMileage cap and mileage fee
A limit on the miles included in a rental. Driving past the limit adds a charge for each extra mile.
what RV rentals costGenerator fee
A charge some owners add for generator use, often billed for each hour of run time.
what RV rentals costOne way RV rental
A rental you pick up in one city and drop off in another. A drop fee usually applies.
the one way rental guideGVWR
Gross Vehicle Weight Rating is the maximum safe loaded weight of a vehicle, set by the manufacturer. Staying under it keeps you safe and legal.
weight limits by RV classRV rental insurance
Coverage that protects a renter and the vehicle owner against damage, liability, or theft during a rental period. Most peer to peer platforms require proof of insurance or offer a protection plan before a booking is confirmed.
the RV rental insurance guideRoadside assistance
A service that provides help such as towing, tire changes, or jump starts if an RV breaks down during a trip. Many rental bookings include a roadside assistance plan or offer one as an added option.
first time rental tipsDrop fee
A charge added when a renter returns an RV to a different location than where it was picked up. The fee covers the cost of relocating the vehicle back to its home base.
how one way RV rentals workSecurity deposit
A refundable amount held by the owner or platform to cover potential damage, excess mileage, or cleaning charges. It is typically returned after the RV is inspected and no issues are found.
the rental cost estimatorPrep fee
A charge that covers preparing an RV for the next renter, including cleaning, sanitizing tanks, and restocking supplies. It is usually a flat amount added to the total booking price.
what an RV rental really costsTow vehicle
The truck or SUV used to pull a travel trailer or fifth wheel that has no engine of its own. Renters need a tow vehicle with enough towing capacity before booking a towable RV.
the RV rentals guideCamping and Stays
Boondocking
Camping in your RV on public land without hookups, usually for free.
the boondocking guideDry camping
Any stay without water, electric, or sewer hookups, including parking lots and basic campsites.
the boondocking guideSelf contained RV
An RV with its own fresh water, holding tanks, and a toilet, so it needs no external hookups for a short overnight stay.
the network that asks for self containmentMoochdocking
Parking your RV on a friend or family member's property, often using their water or power.
Harvest Hosts against Boondockers WelcomeDispersed camping
Camping outside developed campgrounds on public land, with no facilities or marked sites.
free overnight parking optionsOvernight RV parking
A single night stay in a parking lot or rest area rather than a campground, where it is allowed.
free overnight parking optionsMembership camping
A model where campers pay an annual or lifetime fee to access a network of private overnight stay locations. Harvest Hosts and similar programs use this model instead of charging a nightly rate at each stop.
the top RV membership programsHost site
The parking spot offered by a business such as a winery, farm, or brewery that welcomes self contained RVs for an overnight stay with no nightly fee through a membership network. Host sites usually have no hookups and limited amenities.
how Harvest Hosts host sites workBig rig friendly
A campsite or host location with enough room, clearance, and turning space for large motorhomes and long fifth wheel trailers. Not every membership camping location qualifies as big rig friendly.
big rig friendly Harvest HostsSnowbird
An RV traveler who follows warm weather seasonally, typically heading south for winter and north for summer. Snowbirds often rely on membership camping networks to fill overnight stops along long seasonal routes.
the Harvest Hosts guide for snowbirdsFull hookups
A campsite that provides water, sewer, and electric connections directly at the site. Harvest Hosts locations typically do not offer full hookups, which is why self contained capability matters for members.
why self containment mattersFresh water tank
The onboard reservoir that stores clean water for drinking, cooking, and washing while an RV is away from hookups. Tank capacity is a key factor in how long an RV can stay self contained at a host location.
the self contained requirementsFull time RVing
Living in an RV as a primary residence rather than using it for occasional trips. Full time RVers often weigh membership camping costs against traditional campground fees over a full year of travel.
