    What is a pure sine wave inverter?

    In a solar system, an inverter is responsible for converting the DC energy stored in batteries into AC power to supply AC consumers.

    Inverters transform DC to AC

    This conversion is achieved through the collaboration of multiple switches in a closed circuit to produce the AC output. The precision of these switches is crucial in determining the quality of the output waveform, which can be a square wave, sine wave, or modified sine wave.

    square wave, sine wave, modified sine wave

    While an inverter can produce different waveforms, a pure sine wave output is preferable because many electrical products are designed to work best with a sine wave AC power source.
    high-quality and well-designed inverter ensures that the output is purely in the form of a sine wave with minimal conversion losses in the system components.

    How do pure sine wave inverters work?

    In order to comprehend the functionality of an inverter, we can examine its simplified block diagram. Assuming that there is a battery, four switches, and an AC consumer at the output, we can further delve into its operation.

    simplified inverter circuit

    This simplified circuit uses a DC source to power an AC consumer, represented by a lamp. By pairing switches, we can generate AC pulses and alternate the current direction through the lamp.
    By opening switches two and three, the current direction will be as follows:

    current flow direction with switch2 and swith3 on

    If switches one and four are opened, the current will flow in the opposite direction through the lamp.

    current flow direction with switch1and swith4 on

    The lamp in this circuit is actually receiving an alternating current, which it experiences as a square wave. A high-quality inverter operates on a similar principle but includes several functions to improve output quality and conversion efficiency. Switching is performed using electrical switches like FETs and IGBTs, and control pulses are generated by a control circuit. Energy storage elements such as inductors and capacitors aid in filtering and smoothing. The smoother the wave, the higher the quality of the output will be.

    Benefits of using pure sine wave inverter

    Using a pure sine wave inverter offers many benefits. The quality of the waveform directly affects the efficiency and lifespan of appliances. Waveforms with harmonic distortions and sharp edges can cause electronics to overheat or become damaged. Certain devices, such as computers, are unable to function with non-sine wave energy forms.

    Different types of inverters

    Inverters can be classified into two types – High-Frequency and Low-Frequency inverters – based on the size and switching speed of transistors.
    Low-frequency and High-frequency EPEVER inverters
    • High-frequency inverters:

    Use multiple smaller transformers and have over twice the number of components.

    They are not suitable for long-term exposure to high surge loads like pumps, motors, and some high-torque tools due to decreased capacity.

    • Low-frequency inverters

    On the other hand, have larger and more robust transistors that can operate cooler.

    This enables them to tolerate higher amounts of surge power.

  • Charge Controllers

    Charge Controllers

    What is a solar charge controller?

    solar charge controller is a device that is responsible for transferring energy from solar panels to batteries to charge them. Its primary function is to protect the batteries from excessive energy or voltage by preventing overcharging. Additionally, it regulates the rate and amount of charge for the batteries.

    How charge controllers function in a solar power system

    charge controller in an off-grid solar system also prevents reverse current from batteries to solar panels during overnight or cloudy days. Depending on its type, it can improve system efficiency and optimize power harvest from solar panels. Furthermore, a charge controller typically includes monitoring features that allow system parameters such as current, voltage, and energy to be monitored.

    Epever Charge Controller Display Screen

    Ultimately, the charge controller serves to increase battery lifespan and optimize the off-grid system.

    Why do we need a solar charge controller?

    The reason for requiring a solar charge controller is to safeguard and extend the life of batteries.

    Diagram of a solar power system with a charge controller

    Overcharge protection:

    One of the primary protective functions of a charge controller is preventing overcharging, which can harm batteries. The charge controller acts as an intelligent protector by stopping battery charging when the voltage level reaches a certain threshold during the charging process.

    EPEVER charge controllers protect batteries from being overcharged

    Overload / Over current protection:

    The solar charge controller also provides overload and overcurrent protection. When running DC loads directly from the charge controller, it monitors the current demand and stops it if it exceeds a certain limit to prevent battery damage. During charging, if the current flowing into the batteries is too high for the circuit to handle, an over-current event may occur, which can cause overheating or fires. The charge controller can adjust the current flow to the batteries and hard limit it if necessary to prevent this from happening.

    EPEVER charge controllers overload protection

    Over-discharge protection

    To prevent the battery from being drained completely, a charge controller provides over-discharge protection. When the battery’s state of charge (SOC) drops below a certain level, the charge controller disconnects the loads to manage the amount of discharge. This protective function safeguards the battery, limits the depth of discharge (DOD), and extends the battery’s lifespan.

    Monitoring system parameters

    To monitor the performance of a solar power system, a charge controller can provide information on various parameters such as the voltage of batteries, PV modules, charging current, energy consumption, and production. This data can be displayed through a variety of methods including LEDs, LCDs, remote monitoring devices, and cloud interfaces.

    How to choose a solar charge controller?

    When it comes to selecting a solar charge controller, it’s important to consider the different types available. The two main categories are pulse width modulation (PWM) and maximum power point tracking (MPPT) charge controllers. While PWM controllers are cheaper, they are less efficient and best suited for smaller systems where efficiency is not a top priority. In contrast, MPPT controllers are more efficient and safer, making them the recommended choice for larger and more complex systems.

    MPPT charge controllers can track the maximum power point of the solar panels and obtain the maximum solar energy possible. They can generate up to 30% more power compared to PWM charge controllers and perform better in cloudy conditions with lower solar irradiance. On the other hand, PWM charge controllers act as a valve that regulates the charging current based on the voltage of the batteries.

    To choose the right charge controller for your solar power system, consider the size and complexity of your system, the expected solar irradiance, and the efficiency you require. It’s recommended to opt for an MPPT charge controller for larger and more complex systems. However, if you have a smaller system and efficiency is not your top priority, then a PWM controller can be a suitable choice. For more detailed information about the differences between PWM and MPPT charge controllers, we have a comprehensive article that you can refer to.

    Compatibility with Lithium batteries

    It’s important to note that not all charge controllers are compatible with lithium-ion batteries. These batteries have unique charging and discharge profiles, requiring a multi-stage customized charging and discharge configuration that may not be supported by some charge controllers. It’s crucial to choose a charge controller that is specifically designed to work with lithium batteries to ensure their longevity and performance.


    What features you can expect from an MPPT charge controller?

    In general, a high-quality MPPT controller that has been well-designed and manufactured will offer the following characteristics

    •    High MPPT tracking efficiency above 99.5%
    •    High maximum charge conversion efficiency of as high as 98%
    •    Support for both lead-acid and lithium-ion batteries
    •    Programmable
    •    Multiple load work modes
    •    Various protective functions
    •    Temperature derating/protection
    •    Real-time energy statistics function
    •    Local, remote, and cloud monitoring

    What is an Inverter/Charger?

    The term “Inverter/Charger” or “Combined Inverter Charger” refers to a device used in solar energy systems that integrates the functions of a solar charge controller and an inverter into a single unit. This unit is capable of both converting DC to AC and AC to DC. The combination of these functions is typically more cost-effective, efficient, and easier to install, commission, and maintain.

    Inverter/charger: Combining Inverter and Controller

    In situations where there is limited solar radiation or unreliable grid power, an Inverter/Charger is an excellent option because it automatically switches between available sources such as solar panels, external power generators, and battery-stored energy to provide uninterrupted power output for consumers.
    Furthermore, a combined charger inverter provides not only smart switching but also intelligent modes to optimize energy consumption and generation cycles and determine the energy budget balance.
