Do Microinverters work with a battery?

Introduction

As global demand for renewable energy continues to rise, more households continue to choosing solar power as their primary energy source. However, the limitation of solar power lies in its reliance on daylight for energy generation, while household electricity needs are typically around the clock. To address this issue, battery storage systems have emerged at the right time. These systems can store excess electricity generated by solar systems during the day and provide continuous power at night or during outages.

This method of energy storage significantly enhances the efficiency and flexibility of solar systems, especially when batteries are used in combination with microinverters. The energy conversion and utilization rates of the entire system are further improved. So, how does microinverter works in tandem with batteries, and what benefits does this combination offer to homeowners?

The Working Principle of Microinverter and Battery

How Microinverters Convert DC Power from Solar Panels to AC Power

The primary function of a microinverter is to convert the direct current (DC) generated by solar panels into alternating current (AC) for household use. Solar panels produce DC power based on solar radiation, and microinverters directly process this energy and convert it into AC power, which can be used by household appliances. Unlike traditional centralized microinverters, microinverters are installed behind each individual solar panel, independently managing the output of each panel. This design significantly enhances system flexibility and efficiency, ensuring that even if one panel is shaded or malfunctions, the others continue to operate efficiently.

How Batteries Store DC Power

The core function of a battery pack is to store and release DC power. When the solar panels generate more DC power than the household requires at the moment, the excess energy is stored in the battery pack instead of being wasted. This stored energy can later be converted into AC power through the microinverter and used by the household at night, on cloudy days, or during power outages. The energy storage system acts as a regulator in the solar power system, balancing the timing of energy production and consumption, ensuring a continuous power supply throughout the day.

Features of TSUN Balcony Microinverters and DCU

Balcony Microinverter (GEN3 2-in-1 Series)
TSUN's balcony microinverter is a 2-in-1 device designed for residential solar systems. This microinverter can handle the output of two solar panels, offering higher efficiency while reducing equipment costs. Its plug-and-play design makes installation straightforward—users only need to connect the solar panels to the microinverter to quickly convert DC power into AC power for home use. This device is not only efficient and reliable but also supports integration with energy storage systems, allowing users to maximize the use of solar power, whether for immediate consumption or for storage and later use.

DCU (Direct Current Coupling Unit)
TSUN's DCU is a battery pack designed specifically for storing DC power and features plug-and-play compatibility with both solar panels and microinverters. The DCU collects excess DC power generated by the solar panels and stores this energy in the battery. When power is needed, the DCU outputs the stored energy to the microinverter via DC cables, where it is then converted into AC power for household use. The DCU not only efficiently stores DC power but also works with TSUN's P1000 device to provide off-grid power for outdoor use.

Advantages of TSUN DCU+ microinverter

1. Plug-and-play design

TSUN's DCU (DC coupling unit) and microinverter are designed to provide a very good user experience, using a plug-and-play solution. This means that users only need to connect the DCU to the photovoltaic panel and microinverter to start using it, without a complicated installation process. This design saves time and simplifies the system configuration, so that even non-professional users can easily complete the installation and use the equipment.

2. Improved energy utilization

A significant advantage is the improvement in energy utilization. The amount of DC power generated by photovoltaic panels may exceed the immediate needs of the home during the day. This excess power will be stored in the battery through the DCU, thus avoiding energy waste. At night or during power outages, the power stored in the DCU can continue to be converted into AC power through the microinverter, ensuring that the home can still get a stable power supply when there is no sunlight. This energy storage mechanism improves the overall efficiency of the system and makes the home energy supply more reliable.

3. High compatibility

TSUN's DCU is not only compatible with the company's microinverters, but also shows high compatibility. It can be used in conjunction with other devices such as P1000 to provide off-grid power solutions. P1000 has a built-in inverter that can convert the DC power stored in the DCU into AC power and provide power to outdoor devices through multiple output interfaces. This flexible compatibility makes the DCU system not only suitable for home photovoltaic systems, but also supports various outdoor power needs, providing users with more usage scenarios and flexibility.
