Bi-directional Power Supply for Renewable

Bi - directional Power Supply for Renewable is a kind of power electronic equipment that can realize the bidirectional flow of electric energy, and is widely used in the field of renewable energy. Here's how it works:

How it works: Bidirectional energy flow is typically achieved through a full-bridge or half-bridge topology that utilizes high-frequency switching devices (e.g., IGBT/MOSFETs) and pulse-width modulation (PWM) techniques. In inverter mode, the power of a DC power source (such as a battery) can be converted into alternating current; In rectification mode, alternating current can be converted to direct current by filtering and synchronous control.
Core functions: It has two modes of rectification and inverter, which can flexibly switch the direction of energy transmission according to the needs of the working scene and realize the bidirectional conversion between DC and AC. Some high-end models also support seamless on-grid/off-grid switching, enabling millisecond mode conversion via digital signal processors (DSPs) or field-programmable gate arrays (FPGAs).
Advantages and features:
High energy efficiency: The bidirectional power supply can make the energy conversion efficiency as high as more than 95%, which greatly reduces the loss of energy in the conversion process, and can realize energy feedback to further improve energy efficiency.
Flexible power supply: It can flexibly manage power and redirect, store, or feed energy back to the grid according to demand to meet the power demand in different scenarios.
Cost savings: With features such as regenerative braking and vehicle-to-grid (V2G), energy costs can be reduced and resource utilization optimized.
Environmental protection and low carbon: It helps to integrate renewable energy, improve the utilization efficiency of renewable energy, reduce greenhouse gas emissions, and reduce environmental burden.
Application Scenarios:
New energy energy storage system: In solar, wind and other systems, excess electric energy can be stored, and the electric energy can be supplied to the grid in reverse when the grid is low. Household energy storage devices such as Tesla's Powerwall use this technology.
Electric vehicles: As an on-board charger and inverter, it can not only charge the vehicle battery, but also realize functions such as V2G and vehicle-to-load (V2L). For example, some BYD models can achieve 3-7kW reverse discharge to meet the emergency electricity needs of households.
Microgrid system: In the microgrid of islands or remote areas, the multi-directional energy flow between diesel generators, energy storage batteries and renewable energy can be coordinated to ensure the stable operation of the microgrid.
Industrial uninterruptible power supply: In scenarios such as data centers, the two-way interaction between the battery pack and the power grid can be realized, reducing energy storage losses, providing backup power for equipment in the event of a power outage, and ensuring the continuity of power supply.

Lightest and Safest

The lightest and safest 3600W bi-directional energy storage power supply, there is no one.

Adopting EVE lithium iron phosphate battery, energy density is more than 20% higher than peers, the product is safe and reliable.

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.
