All-in-One Bidirectional Battery Inverter

The All-in-One Bidirectional Battery Inverter is a highly integrated core control unit in solar equipment, which integrates functions such as "bidirectional energy conversion, battery management, system monitoring, and grid interaction" into one, greatly simplifying the design, operation and maintenance of solar energy storage systems. In solar energy equipment, its role is not only limited to energy conversion, but also assumes the role of "system hub", which can be carried out from the following four aspects:
1. Core function: one-stop solution to the energy flow of solar energy system
The integrated bidirectional battery inverter realizes the whole-process management of solar power generation, energy storage, electricity consumption, and grid interaction through highly integrated hardware and algorithms, replacing the scattered components of the "inverter charging and discharging motor BMS (battery management system) controller" in the traditional system, and the core functions include:

Bi-directional AC/DC conversion opens up the energy channel
DC → AC (inverter): Converts the DC generated by solar panels (or the DC power of energy storage batteries) into AC power (such as 220V/50Hz) that meets load/grid standards to ensure the normal operation of AC loads such as household appliances and industrial equipment.
AC → DC (rectification): When there is a surplus of solar power generation, the excess electricity (or cheap electricity during the off-peak hours of the power grid) is converted into DC power and stored in the energy storage battery to avoid energy waste; At the same time, it supports charging the battery directly from the grid to cope with extreme conditions such as continuous rainy days.
For example, the integrated inverter can monitor the output of photovoltaic panels (such as 200-450V DC), battery status (such as 48V DC) and grid voltage (220V AC) in real time, and automatically switch the working mode - priority inverter power supply during the day, and rectify the excess power to store the battery; When the PV power is stopped at night, the inverter battery can supplement the load, and then draw power from the grid when it is insufficient.
Integrated battery management system (BMS) to ensure the safety and efficiency of energy storage
In traditional solar systems, the BMS needs to be configured separately, but the integrated inverter has a built-in BMS, which can directly carry out refined management of energy storage batteries (such as lithium iron phosphate batteries and ternary lithium batteries).
Real-time monitoring of battery voltage, current, temperature, SOC (state of charge), SOH (state of health);
Dynamically adjust the charge and discharge strategy (such as limiting the maximum charging current and setting the discharge cut-off voltage) to avoid risks such as overcharge, overdischarge, and short circuit, and extend battery life (usually by 20%-30%);
It supports the battery balancing function to ensure the consistency of multiple cells and avoid the overall performance degradation caused by the rapid decay of a single cell.
Smart grid interaction to optimize energy economics
Through the linkage with the power grid, the integrated bidirectional inverter realizes "self-generation and self-consumption, surplus power grid, peak and valley arbitrage", and maximizes the economic value of solar energy:
Surplus power grid: When the solar power generation exceeds the load demand and the battery is fully charged, the inverter will invert the excess power and feed it into the grid (subject to grid voltage, frequency, and harmonic standards), and the user can get electricity price subsidies or electricity sales income (such as

Introduction of all-in-one bidirectional battery inverter
Basic concepts
The all-in-one bidirectional battery inverter is a multi-functional power conversion device, which plays an important role in the power system, and can realize the bidirectional conversion between direct current and alternating current. This type of inverter is often used in conjunction with a battery energy storage system to convert the direct current in the battery into alternating current for use by the load, and also to convert the alternating current generated by the grid or renewable energy generation equipment into direct current to charge the battery.

Key features:
Highly integrated
The all-in-one design integrates multiple functions such as charging, discharging, and inverting into a single device, reducing the number and footprint of devices in the system, and reducing the complexity of installation and maintenance. For example, in the home energy storage system, users no longer need to install multiple independent charging equipment, inverters, etc., which greatly simplifies the system construction process.

Bi-directional energy conversion
The ability to convert power in both directions is its core feature. During peak power consumption or power outages, it can invert the direct current stored by the battery into alternating current to supply power to homes, commercial places or industrial equipment to ensure the continuous supply of electricity. When the electricity consumption is low or the renewable energy generation is excessive, the alternating current can be converted to direct current to charge the battery, so as to realize the effective storage and rational utilization of electric energy.

Intelligent control and management
It is usually equipped with an advanced intelligent control system that can monitor the status of the battery (such as power, voltage, temperature, etc.) in real time, the condition of the power grid, and the demand of the load, and automatically adjust the charging and discharging strategies based on this information. For example, when a low grid price is detected, the inverter is automatically controlled to charge the battery; When it detects that the battery is low or the load demand increases, the electric energy in the battery is released in time.

Strong compatibility
It is compatible with many types of batteries (e.g., lead-acid batteries, lithium iron phosphate batteries, etc.) and power sources (e.g., renewable energy generation equipment such as solar panels, wind turbines, and power grids). This makes it flexible for use in different application scenarios, whether it is a small household energy storage system or a large commercial or industrial energy storage project.

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.
