The High Efficiency Bi-directional Power Unit is a key upgrade of solar equipment from "usable" to "efficient", and its core value is to directly improve the economy, reliability and endurance of the system by reducing energy loss. In residential scenarios, it allows users to achieve higher self-sufficiency with fewer photovoltaic panels and batteries; In industrial and commercial scenarios, loss reduction in large-scale applications can translate into significant cost savings; In the off-grid and new energy integration scenarios, it is the "invisible cornerstone" to ensure the stable operation of the system. With the surge in PV installations and the decline in energy storage costs, high-efficiency bidirectional power units will become one of the core technologies to promote the transformation of solar energy from "supplementary energy" to "main energy".
Introduction to high-efficiency bidirectional power units
Definitions and Principles
High Efficiency Bi - directional Power Unit is a power conversion device that can realize the bidirectional flow of electric energy. It is based on advanced power electronics technology, using the switching characteristics of power semiconductor devices (such as IGBTs, MOSFETs, etc.), through precise control algorithms, to convert electrical energy between DC and AC in both directions. In the forward conversion, the direct current can be converted into alternating current for the load use; When the reverse conversion is carried out, the alternating current can be converted to direct current and stored to achieve flexible energy allocation.
peculiarity
Efficiency
Advanced circuit topology and control strategy are adopted to reduce the loss of energy in the conversion process and achieve high conversion efficiency. Generally speaking, its conversion efficiency can reach more than 90%, which means that in the process of electric energy conversion, most of the electric energy can be effectively utilized, reducing energy waste and improving energy efficiency.
Bidirectional energy flow
Different from traditional unidirectional power conversion equipment, it supports the bidirectional transmission of electrical energy. It can not only reverse the direct current in the energy storage device (such as a battery) into alternating current to supply power to the AC load, but also rectify the mains or other AC power sources into direct current to charge the energy storage device. This bidirectional energy flow makes it have a wide range of application value in energy storage systems, renewable energy power generation systems and other fields.
High power density
Large power output can be achieved within a limited volume and weight. By optimizing the circuit design and adopting high-performance power devices, the power density per unit volume and unit weight is improved, making the device more compact and lightweight, and easy to install and integrate into various systems.
Intelligent control
Equipped with an advanced intelligent control system, it is able to monitor and adjust the operating status of the power unit in real time. According to different application scenarios and needs, the output power, voltage and frequency and other parameters are automatically adjusted to achieve accurate control and management of energy. At the same time, it also has fault diagnosis and protection functions, and when there are abnormal conditions such as overcurrent, overvoltage, and overheating, protection measures can be taken in time to ensure the safe and reliable operation of the equipment.
Application scenarios
Renewable energy power generation systems
In renewable energy power generation systems such as solar and wind energy, high-efficiency bidirectional power units play a key role. When there is a surplus of renewable energy generation, it can rectify the excess electric energy into direct current and store it in energy storage devices such as batteries; When the power generation is insufficient or the load demand increases, the direct current in the energy storage device can be inverted into alternating current, which can be supplemented to the grid or supply power to the load, which improves the utilization rate and stability of renewable energy.
Lightest and Safest
The lightest and safest 3600W bi-directional energy storage power supply, there is no one.

Bare machine weight 40KG, size 550 * 321 * 464.
Industry Leading Level
PV input support up to 2000W, input range 12V-160V, in the industry leading level.
After waking up the system, 5W standby power consumption, almost the lowest in the industry.
High-power super fast charging
AC output efficiency is very high, the average efficiency of more than 92%, the whole capacity conversion efficiency of more than 85%, the same level of products is almost the industry's best standard
Keep your equipment working
Usually, the battery in the work equipment cannot last for a whole day or more, which requires us to plan the work in advance and prepare a lithium portable power station with sufficient power.
Continuous energy supply
In this off-grid situation, you simply cannot find a source of electricity to charge your work equipment. If this place is far from the power supply place, the round trip will delay a lot of working time, increase costs and reduce work efficiency.
Easy to move
The overall weight of Energipak 3840 is close to 40kg. We use rollers at the bottom of the battery to move it. The hidden telescopic rod design allows you to move it as easily as a suitcase.
Source of power generation
Even if you already have your own lithium portable power station, its power will be exhausted one day under high-intensity and long-term working conditions. Therefore, how to recharge portable power supplies is also one of the headaches, because mains power is not always guaranteed.
