Renogy 400 Watt Solar Kit

How Does The Renogy 400w Rv Solar Kit Differ From The Competition

Both Renogy and ECO-WORTHY make similar 400W solar kits for RV applications.

The closest ECO-WORTHY 400W RV kit is a 24V x 60A setup, which provides significantly more power than the Renogy for about the same price.

Both solar kits feature corrosion-resistant aluminum frames for durability and are suitable for outdoor off-grid installations.

Both kits come with four slim monocrystalline solar panels with 21% energy efficiency. While the Renogy solar kit comes with a maximum voltage of 12V, the kit from ECO-WORTHY has a maximum voltage of 24 volts.

Another difference between these solar kits is the amperage of the charge controller. The Renogy solar kit includes a 30A PWM charge controller suitable for up to 1,024 Watters, while the ECO-WORTHY solar kit has a 60A charge controller that can deliver up to 2,048 of Watts of solar power with additional panels.

One major difference between Renogy and ECO-WORTHY is in their warranty. Renogy offers a 25/5 warranty on power supply, whereas ECO-WORTHY’s guarantee is for just one year.

How To Install 400 Watt Solar Panel System

Our guide details everything you need to install a campervan solar panel system.

Its written to suit any size of system so it makes reference to how to install multiple panels.

It may come in useful when considering upscaling your set up though.

Theres also a section about the tools you need to install your campervan solar panels.

Some of these tools can be quite expensive so unless you expect to get a lot of use out of them in the future, try to borrow them where possible.

We do encourage you to invest in a multimeter though and keep it in your RV toolkit while travelling and living in your van.

Check out our complete guide for how to use a digital multimeter in your camper.

What Can A 400 Watt Solar Panel Power

How much 400 watts of solar panels can power depends on a number of variables including the time of year, the weather, your location and the type of charge controller you install.

But heres an idea of what you might expect to get on an average day of 4 peak hours of sun with an MPPT controller.

400 watts of solar panel will provide about 120 128 amp hours per day.

Thats about enough to run:

• an inverter for a TV and charging laptops,
• a good sized, energy efficient fridge,
• recharge a plenty of small devices on a USB like phones, tablets and kindles,
• run your roof vent during day and night to stop condensation,
• keep a composting toilets fan running 24/7,
• run a diesel heater for a few hours and
• switch on a few LED lights inside the campervan.

Bear in mind this is based on an average sun light day.

A 400w systems gives you a couple of days in reserve, depending on your usage and without other sources of recharging.

You may not be able to replenish the batteries everyday so consider keeping something back as contingency to avoid cycling the batteries more than necessary.

How Does Solar Irradiance Impact Power Output

Solar irradiance has a significant effect on the power output of your solar panels and can often be the difference between maximum efficiency and as little as 10 percent efficiency. Solar irradiance refers to the intensity of the sun at a given location. The more directly the sun hits your panels, the closer the energy production will be to the panels maximum efficiency. The states that are best for solar power are those closest to the equator, where the sunlight hits at an angle closest to perpendicular, meaning a higher intensity.

Solar irradiance is often measured in kilowatts per square meter, and many solar calculators automatically consider this measurement in your area. You can find online tools to estimate your solar irradiance, although its challenging to work this measurement into efficiency calculations accurately, given the other factors. For most homeowners, it suffices to know that areas with higher solar irradiance measurements will generally be a better fit for solar installation and will see higher levels of energy production per 400-watt panel.

Heres a look into solar irradiance:

Is Panel Voltage Important

Solar system voltage including open-circuit voltage and short circuit current is an often-overlooked measurement on panel datasheets, but its an important one to consider, especially for residential solar applications. Its easiest to imagine voltage in terms of how liquids behave. Suppose you have a large water tank with a hose leading out of the bottom. When you open the valve to the hose, water will flow out of the hose at a speed proportionate to the amount of water in the tank . The more water you have in the tank , the more force will be exerted at the exit point .

Everything that uses electricity comes with a voltage rating, which determines how much voltage from your panels is required to power it. For example, an electric stove often requires 240 volts to power, while a 12-volt battery requires just over 12. A solar panel with a rating of 24 volts could supply power to a 12-volt battery, provided you have an MPPT charge controller, but it would fall far short when it came to power the stove. Ultimately, your panel voltage will determine what items your solar array can provide power for. Keep in mind that panels can be run in series using branch connectors to ramp up the voltage to your inverter.

What Types Of Financing Options Does Klarna Offer

• Flexible Month-to-Month: Flexible Month-to-Month purchases are standard purchases with no fixed term commitment, similar to a traditional credit line. You decide whats best for you you simply need to make at least your minimum monthly payment. These are also sometimes called standard purchases.
• Planned Payments: Planned Payments is a promotional offer which allows eligible orders to be purchased with a reduced APR. With planned payments, you will have a fixed monthly payment. The APR varies based on the current available promotions.
• No Interest If Paid In Full: No Interest If Paid In Full is a promotional offer in which interest is deferred during the promotional period. If the entire balance is paid before the expiration date, no interest will be charged. Keep in mind, you still need to make at least your minimum monthly payment. These are also sometimes called deferred interest purchases.

Who Will Suit A 400 Watt Solar Panel System

A 400 watt solar panel set up is a good size for a couple or small family with a medium to large sized camper with roof space for the panels.

It can support wild camping or boondocking in your RV for relatively long periods from early spring through to late autumn with careful use and monitoring of the battery levels.

A 400w system is the point where you should be able to run your entire campervan electrical system 100% off solar, year round. No need for shore power or driving.

Even with a 400 watt system, if your aim is to be completely independent of hook up, youll need to watch your consumption and battery levels closely.

If your ideal solar system is larger than 400w, build the system with scaleability in mind.

You can add panels and batteries in the future as your needs grow and budget allows, assuming you have space on your roof.

You could consider extra juice from a portable solar panel system but thats for another post.

How Much Energy Can Renogy 400 Watt Solar Premium Kit Collect

During summer, when the sun is high in the sky and the day lasts for at least 14-16 hours, on average one may expect the single solar panel to provide ~60 watts of electric power for at least 10-11 hours.

Thus, all four solar panels may provide ~240 watts for at least 10h and are able to almost fully charge 12V 200Ah battery that is being discharged down to 80% DoD. If the solar panels are positioned at a ‘perfect’ angle toward the sun during the day, they may collect even more energy.

Renogy 400 Watt 12 Volt Off-The-Grid Solar Premium Kit is often combined with one of the 12V 200Ah Renogy batteries – AGM, Pure Gel, Hybrid Gel – each one having very similar performances, but also each being optimized for a slightly different purpose.

This solar panel kit may be used with smaller batteries as well – charge controller is monitoring the battery condition and adjust the charging process as required. If the battery is fully charged, the charging stops.

Long Story Short: Renogy 400 Watt 12-Volt Off-The-Grid Solar Premium Kit is for many travelers and camping enthusiasts ‘entry-level’ solar kit – it cannot power, for example, RVs AC units, or standard 55 lbs electric trolling motor.

But, Renogy 400 Watt 12-Volt Off-The-Grid Solar Premium Kit ensures that people have 50-100 watts of power 24 hours per day , which is often more than enough to run small TV, camping fridge, telecommunication equipment, lights, fans and similar.
