The Honda EU2200i is probably the most all-round portable generator we've seen. It has all the right specifications that make it a well-balanced generator that would be perfect for any tailgating party. If the 120cc engine and the 1800W power rating took you by surprise, then you're in for a wild ride with the EU2200i.

Weighing in at a mere 47 pounds, this is one of the lightest portable generators you can find on the market. Not only does this mean you'll have an easy time moving it around, but it also means that it will leave you with enough room in the trunk of your vehicle to stock even more supplies for the tailgating party.

In addition, while the 120cc engine is powerful, it doesn't really sacrifice on noise levels. The Honda EU2200i has noise levels of around 48 dB which is great news for tailgaters who simply want to relax and enjoy the company of their friends. 

As you may have already guessed, the EU2200i is an inverter type of generator, and this explains why it has very low noise levels. Apart from being quiet though, it also conserves fuel better than other generators in its category thanks to Honda's Eco Throttle system which can give you runtimes of between 3 to 8 hours

Factors to Consider When Buying an MPPT Charge Controller

When selecting a solar charge controller, the key factors to consider include:

  • The system voltage
  • The system array current ( Imp and Isc)
  • The type of battery

The type of battery maintainer you purchase depends on the specific use case, and it’s a tradeoff when it comes to maximizing battery longevity. Also, PWM controllers are affordable. 

They are also suitable for use in small wattage solar electric systems. Additionally, their efficiency is the same as MPPT solar panel battery charges in hot climates. Choosing the incorrect charge controller can lead to as much as 50% of loss in power in a portable panel.

It’s a common mistake that owners of RVs or even campers make. They for a high voltage solar panel at the most affordable cost per watt. Then, they connect this solar panel to a PWM charge controller, and this leads to the loss of well over 50% of the power available. 

What is An MPPT Charge Controller

MPPT is an acronym for Maximum Power Point Tracking. It’s a feature that lets the input power of an MPPT controller be equal to the output power. 

Thus, if a solar array has an output voltage of (18V, 48V) is higher the level of battery storage which is usually 12Volts. An MPPT controller will bring it down to 12V but will address the decrease by increasing the current level. This way, the power level remains leveled. 

Since you won't lose the power produced from the solar, the MPPT controllers let you connect several panels in series. Such an approach helps improve the total voltage level of the panel without losing any precious solar power.

The main goal of using MPPT is to ensure the solar panels maximize their performance. To be specific, the charger ensures the solar panel can function at optimal current and voltage levels. The term for this is “maximum PowerPoint.”

More so, the MPPT charge controller also works to convert the solar produced voltage, into optimal voltage. This provides optimal charging current for the battery. More so, the main goal of a solar charge controller is to prevent the system from losing the solar produced power. Plus, it also helps to get maximum power from the solar panel, which is connected in series. 

The other benefit of an MPPT system is that it helps reduce the amount of wires and sizes required to connect the panel to a controller. This is due to the broad input voltage range, which lets you connect several panels in series. Such a unique connection helps improve the voltage, but the level of amps stays constant. 

MPPT controllers are also affordable than PWM models but are highly efficient when it comes to regulating the charge. Remember to consider this aspect when you want a suitable charge controller for your needs. They all have indications which make them easy to identify.

Charge Controller Sizing

The primary task in sizing a charge controller is to determine its voltage and current levels. Then, use these metrics to choose the correct charge type. Above all, you should also consider the type of charge regulator that would be suitable for your system. This way, you won’t have to pay more money than the amount you require. 

Furthermore, you also won’t have to purchase a device that could lead to poor system performance. Or even worse, it may even cause damage to the other components in your system. The best safety factor level to consider would be one that averages at 1.25. By this factor, the maximum input voltage and current of the charge controller increase significantly. Thus, the charge can adjust and meet the sporadic increases in voltage and current due to increased temperature levels. 

Commonly Made Mistake During Charge Controller Installation

At this point, it would be good to assume that you have found the correct type of charger and size for your off-grid power supply needs. The next step is to connect it to the system with other components for power supply. Just you should know, wires and connections are a crucial aspect of every solar system today. Here are the common factors to consider when you want to plug in your charge controller: 

  • You should only connect DC loads to the charge controller`s output. The AC loads are only to be connected to the output of the inverter. 
  • Also, specific appliances such as low voltage electronic devices should be connected directly to the battery
  • In a small DC system that has a charge controller, the only fuses you will need is the one integrated into the charge controller. More so, in the large DC systems, you may have to get a fuse on the positive terminal of the battery.
  • You should always mount the charger close to the battery. It's important because the system requires accurate measurements of the battery voltage for optimal functionality. Thus, even a slight drop in system voltage should be stopped at all costs. 
  • The conventional charge controller features three terminal connections. These include connections for the battery, DC connections, and for the array. At this point, the role of the charge controller disconnects the battery to stop overcharging. More so, it also disconnects the DC loads that are connected to the controller, to prevent any over-discharging issues. 
  • Each appliance that is connected directly to the battery rather than the “DC load” terminal of the charge controller has a notable side effect. It causes the battery of the over-discharging function of the charge controller to become useless. 
  • You should connect the inverted directly to the “DC load” terminal that is on the charge controller
  • When connecting an inverter to the charge controller, remember to consult the charge controller data manual. Search for information on the charge controller power, and whether its capable of powering the inverter. If not, then connect the inverter with the high-power rating to the battery directly. In such an instance, this will cause the over-discharging function to become useless.

Remember That

Sometimes we are all forced to shop on a budget. However, this should not be the case when you want to purchase a solar charge controller. The cheap charge controllers have a low current “DC load” terminal. Thus, their only goal is to stop any over-discharging issues that may occur on the battery. 

You may only be able to connect a low power 12V lamp or any other device with the same power level to this terminal. At such a point, the terminal might switch off, to help stop over-discharging issues on the battery. If this is the case, consider connecting the rest of the components directly to the battery. Why? Well, its because there is no way to disconnect these loads from the battery when over-discharging issues occur. 

Finally

When you have a solar array or panel at home, you should know of the importance of using it the right way. In this guide, we have identified some of the best MPPT charge controller reviews on the market for you to consider. When you have information on one of these products, you will enjoy exceptional charging performance each time. Not only will your panels charge efficiently, but they will also be safe from various issues. These include problems such as overloading, over-discharging, and more.

Thus, it’s crucial that you learn about the specific type of charge which is suitable for your panel. This way, you can charge your devices safely and with optimal efficiency levels.
