What Factors to Consider When Buying a Solar Generator for EV Charging?

1. Power Needs (Wattage)

The wattage of a solar generator defines its capacity to power and charge devices. 

This factor is one of the most critical when selecting a solar generator specifically for EV charging. Different EVs have varying power consumption rates. 

For instance, a typical EV like the Nissan Leaf might consume about 30 kWh for a full charge. 

If you’re planning to charge your EV from 0% to 100%, you should ensure that the generator has enough output to accommodate this need.

However, if you just need to top up your EV’s battery for a short drive or maintain its charge during extended parking periods, a lower wattage generator might suffice. 

Understanding your charging habits and travel patterns can also provide insights into the right generator size. 

For daily commuters, ensuring a full charge overnight would be crucial, while occasional drivers might only require partial charges. 

It’s worth noting that charging an EV to 100% isn’t always necessary or recommended, as many manufacturers suggest charging to around 80% to prolong battery life. 

This means that for some, a solar generator with slightly lesser capacity could still meet their charging needs effectively.

Lastly, you need to differentiate between continuous and peak wattage when evaluating solar generators. 

Typically, solar generators will list two wattage numbers. 

The continuous wattage represents the power the generator can consistently provide, while the peak wattage caters to short bursts of higher power draw, like when an appliance starts up. 

For example, if an EV charger pulls 1,500W continuously but surges to 2,500W momentarily when initiating the chosen generator should handle both these power demands.

I’ve made sure to include various solar generator options in my recommendations, catering to both these wattage specifications.

2. Battery Capacity and Depth of Discharge (DoD)

The battery capacity of a solar generator is measured in watt-hours (Wh) or milliampere-hour (mAh) and indicates the total amount of energy the battery can store. 

Think of it as the “fuel tank” of the generator: the larger the capacity, the more energy it can hold, and consequently, the longer it can power or charge devices. 

For EV users, having a solar generator with a substantial battery capacity means being able to charge their vehicles more fully or multiple times before the generator itself needs recharging.

For example, if an EV requires 30 kWh for a full charge and you have a solar generator with a battery capacity of 40 kWh, theoretically, you can charge the vehicle to full and still have some reserve left. 

However, that leads us to the second factor, the Depth of Discharge (DoD).

DoD refers to the percentage of the battery’s capacity that has been used up. 

Not all batteries are designed to be fully discharged. Frequently discharging a battery to its maximum DoD can shorten its lifespan. 

For instance, if a battery has a DoD of 80%, it means you should ideally only use up to 80% of its total capacity before recharging it. 

In the earlier example, with a 40 kWh solar generator, you’d ideally want to use only 32 kWh (80% of 40 kWh) to maintain the battery’s health.

Therefore, while a solar generator’s battery might boast a certain capacity, the actual usable energy might be less, primarily due to the DoD. 

This distinction is crucial when calculating how much charge you can provide to your EV.

I personally recommend that you opt for a solar generator that can meet at least 75% of your EV’s total charging needs with at least 80% Depth of Discharge (DoD) in mind.

3. Input Ports and Charging Options

Input ports define how a solar generator can be recharged. 

Most solar generators are equipped with ports that allow them to be charged via solar panels. 

For instance, a solar generator might have a dedicated port compatible with certain types of solar panels. 

The more universal and varied these ports are, the more options users have in selecting their solar panels or integrating the generator into existing solar setups.

Beyond solar charging, many modern solar generators also come with AC input ports, allowing them to be charged directly from a regular wall outlet. 

This feature becomes especially useful during extended periods of cloudy weather or when solar charging isn’t a feasible option. 

For those on the move, some generators also provide DC input ports, making it possible to charge them via a car’s 12V or 24V outlet

Such versatility ensures that the generator’s battery remains topped up, ready to charge the EV when needed.

I’ve ensured to include generators that offer a range of input ports in this guide, giving you the flexibility to choose a generator that aligns with your charging needs.

4. Solar Charge Controller

The solar charge controller acts as a regulator in a solar power system, managing the power flow between the solar panels and the battery storage. 

It ensures that the battery is charged without overcharging or undercharging, thereby extending the battery’s lifespan.

There are primarily two types of solar charge controllers: PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking). 

PWM controllers are more basic and are generally cheaper. They are suitable for smaller systems and where the solar panel’s voltage matches the battery voltage.

However, they aren’t as efficient in converting the solar panel’s voltage, which can lead to potential power loss.

On the other hand, MPPT controllers are more advanced and can adjust their input to harvest the maximum power from the solar panels, converting excess voltage into amperage. 

This means that they can be 30% more efficient than PWM controllers, especially in colder temperatures. 

Most of the solar generators in this list come equipped with MPPT controllers, offering better efficiency and optimizing the energy harvest from the solar panels.

5. Expansion Options

No one can deny that having a buffer or room for growth is always beneficial, especially in the realm of energy solutions.

When it comes to solar generators, expansion options play a pivotal role. 

This flexibility allows users to enhance their system’s capacity, adapting to growing or changing power needs. 

For instance, as electric vehicles evolve, newer models with greater battery capacities might necessitate more powerful charging solutions. 

If your solar generator is expandable, it can accommodate these advancements without the need for a complete overhaul. 

Furthermore, even if your EV needs to remain constant, you might find other applications for your generator, like powering home appliances or supporting outdoor activities. 

This is why I’ve prioritized solar generators that offer easy expandability, be it through additional solar panels, battery packs, or both.

6. Portability & Weight

The easier it is to move and transport a solar generator, the more versatile and convenient it becomes for the user.

In case you frequently shift between locations or embark on road trips, it’s better to opt for a compact and lightweight unit. 

However, if you intend to keep the generator in your garage or a fixed location for the majority of the time, you might prioritize a higher power output or more substantial battery capacity, over portability.

I personally recommend looking for solar generators that offer a balanced blend of both these elements.

For instance, some modern generators come with sturdy wheels and handles, which make them easier to move without compromising on their energy output.

7. Warranty

A warranty isn’t just a piece of paper; it’s a testament to a manufacturer’s confidence in their product. 

When considering a solar generator, the warranty can provide peace of mind, ensuring that your investment is protected against unforeseen defects or malfunctions. 

For instance, if two solar generators are equally matched in features and price, but one offers a longer warranty, it might be a wiser choice to opt for the latter. 

Additionally, you should understand what the warranty covers. Does it only cover certain parts, or is it inclusive of labor costs for repairs? 

Some warranties might only address specific components, like the inverter or the battery, while others might offer a more comprehensive coverage.

Lastly, always read the fine print. Some warranties might have conditions, like requiring regular maintenance checks or using specific accessories, to remain valid. 

That’s why in this guide, I’ve made it a priority to only include solar generators that offer at least a 2-year warranty
