The Best Solar Generators for RVs: How to Choose

It’s crucial to think about how to choose the best solar generator for your RV, taking into account many crucial elements, as given below, while choosing the ideal solar generator for your RV excursions, including camping, travel trailers, and tailgating:

Battery Capacity

Battery capacity is a crucial factor when choosing a solar generator for your RV. The ideal capacity depends on your RV’s energy needs and charging frequency. Aim for a generator with 50% more capacity than your daily requirement for backup. Keep in mind that higher capacity entails greater expense. Calculate your RV’s energy needs precisely, considering factors like LED bulbs (7-10W), laptops (54W), or air conditioners (2000W). A typical solar generator like Infinity 1500 has a 1512Wh capacity. Large RVs can need up to 20 kWh daily, while small vans may require as little as 3 kWh. Your generator should match your specific energy needs.

Charging and Charge Cycle

A solar generator’s multiple charge cycles refer to how many times it can fully charge and discharge before the battery starts losing capacity or failing. A reliable larger solar generator should offer 2000 or more charge cycles for long-lasting performance. Having various charging options, such as campgrounds, EV stations, and solar panels, provides flexibility. For solar-only charging, consider your RV’s energy consumption realistically. RVs that consume a lot of energy could need a solar power system like EcoFlow’s Power Kits. 

Quick Recharging

Having a solar generator that charges quickly is super important for RVs. Why? Because when you’re on an RV trip, you use a lot of things that need electricity, and that can drain your power. A fast-charging solar generator can fill up its power during the day, so you have enough for the evening and night. When you can’t access the standard power grid, this is extremely useful. 

Inverter Rating & Type

When choosing an RV solar generator, inverter rating and type are vital. Inverters convert battery DC power to 120-volt AC power. Key considerations:

Inverter Ratings

Continuous Rating: This tells you how many watts of AC power the inverter can produce steadily for an extended period. It can range from 100 watts to over 3,000 watts.

Surge Rating: Surge output refers to the inverter’s ability to deliver a brief burst of power, typically for a few seconds. Appliances like refrigerators and power tools need this extra power during startup.

Choosing the Right Wattage

Select a solar generator that can produce the required amount of power (in watts) for the 120-volt appliances you plan to use, including handling startup surges. You can find this wattage requirement on the appliance or in its user manual.

Inverter Types

Pure Sine Wave: This type produces high-quality AC power similar to what your home’s power outlet provides. It’s ideal for sensitive electronic devices.

Modified Sine Wave: This type generates lower-quality AC power suitable for basic electrical devices like power tools. Computers and other contemporary equipment might not be able to be powered by it.

Efficient Operation

Running a generator at 100% output is not recommended as it can quickly drain the batteries. It’s better to operate at 50% output for efficiency and prolonged operation. If you plan to power all your appliances, consider doubling your power needs estimate to maintain efficiency.

Additionally, choosing a solar generator with a high-quality pure sine wave inverter is advisable as it provides clean and stable power, safeguarding your devices from voltage fluctuations and potential damage.

Solar Input Capability

When you’re picking a generator, look at its “solar input capability.” This tells you how fast you can charge it with solar panels. If it has a higher number, it can charge because you can connect more solar panels. But remember, extra panels can make it more expensive.

Battery Chemistry

Battery chemistry plays a crucial role in the performance of solar generators, and the majority of modern solar generators use lithium-ion batteries for several compelling reasons:

1. Compared to more traditional battery types like lead-acid batteries, lithium-ion batteries, which serve as power banks, can store a significant amount of energy in small, light containers.
2. They can maintain their charge without needing a trickle charger when not in use.
3. Since lithium-ion batteries don’t have memory problems, they can be recharged at any degree of drain without losing capacity.
4. These batteries can be rapidly charged to nearly 100% capacity, offering quicker recharge times compared to other battery types.
5. Lithium-ion batteries can endure numerous charge and discharge cycles before experiencing a reduction in overall capacity, ensuring prolonged usability.

Mobile solar generators typically employ one of two main types of lithium-ion batteries:

• Lithium Nickel Manganese Cobalt Oxide (NCM or NMC): A more budget-friendly option with a slightly shorter cycle life.
• Lithium Iron Phosphate (LiFePO4 or LFP): Generally pricier but known for its extended cycle life.

The number of charge cycles a larger solar generator’s battery can endure typically ranges around 500 times, which translates to about 2 to 3 years of usage before noticing a capacity reduction.

Also, Consider efficiency, app control, expandability with extra batteries, charging speed, and emergency power capabilities when choosing the best solar generator.

Types of Power Output Ports Available

When choosing an RV solar generator, it’s crucial to consider the number and types of power output ports available:

USB-A and USB-C Ports: 

Use for charging small devices like phones, tablets, and cameras.

AC Outlets: 

These provide 120-volt power and can power larger devices like laptops, TVs, and kitchen appliances.

DC Ports (usually 12 volts): 

Used for devices that run on DC power, such as car refrigerators and air pumps.

Consider Your Needs: 

• Solar generators come with varying port combinations, including USB, AC, and DC outlets. Assess your device needs and ensure the generator has suitable ports to power all your RV equipment. Different models provide different port setups, so choose one that aligns with your specific requirements for a successful RV journey.

It’s critical to match your solar and generator systems’ power requirements with those of your air conditioner.

Is There a Solution When My Solar Generator Lacks 

An RV Plug?

If your solar generator lacks a 30 amp RV plug, it can be inconvenient for campsite power. RVs typically need a special 30 amp plug, not the standard household 110/120V plug. The Zero Point Energy Titan is the only generator with a 30 amp RV outlet in this category, simplifying RV power connection. If your generator lacks this feature, you can use a 30 amp RV adapter in one of the AC ports to connect your RV, eliminating the need for multiple extension cords.

In order to boondock, how many solar panels do I need?

The number of solar panels required for boondocking relies on battery capacity and appliance wattage. Calculate by adding battery amp hours (Ah) and appliance wattage. For instance, with a single 12V 100Ah battery, you need at least 3x100W solar panels. With two 12V 200-250Ah batteries, opt for 4x100W or 2x200W solar panels.

A 100W solar panel yields 30Ah battery charge in 5-9 hours of sunlight. For essentials like lights, fans, fridges, and water heaters, 300W panels are adequate. To power a 1,000W microwave, add a battery and use at least 400W solar panels.

In what location on the RV should I install the solar panels?

The best place for solar panels on an RV is usually the roof, as it’s convenient and efficient. However, if there’s limited roof space, a portable stand can be a good alternative. Portable stands allow you to position the panels for optimal sun exposure. This flexibility can be advantageous because roof-mounted panels can’t tilt to face the sun directly, potentially reducing their power output. Roof panels can also be challenging to keep clean from debris. Despite these factors, many people prefer roof panels for their convenience and stability, especially in windy conditions.

Should I Use a Soft Starter for My RV?

Incorporate an RV Soft Start Device into your solar generator setup, especially for powering large appliances like air conditioners.
