Our 700W bidirectional inverter board is engineered for energy storage applications. Here are its standout features:
Two-Way AC-DC Conversion – Seamlessly switches between inverter (discharge) and charger (charge) modes, maximizing system efficiency.
High Efficiency – Achieves up to 91% conversion efficiency, minimizing energy loss during both charging and discharging.
Dual Battery Compatibility – Supports both lithium-ion batteries and lead-acid batteries, giving you flexibility in system design.
Built-in Battery Management – Includes protection for over-voltage, under-voltage, over-current, and short circuit, ensuring safe operation.
Compact Form Factor – At 132 x 185 x 50 mm, this inverter PCB fits easily into portable power stations, solar cabinets, and DIY projects.
Peak Power Capacity – Handles up to 1400W peak power, providing a buffer for startup surges from motors or compressors.
Intelligent Control Interface – Compatible with external controllers for system monitoring and automated energy management.
A bidirectional inverter board, also known as a two-way inverter, combines the functions of an inverter and a charger in a single circuit board. It enables power to flow in both directions:
DC → AC (Discharge mode): Converts battery DC power to AC power for running household appliances, tools, and electronics
AC → DC (Charge mode): Converts grid or generator AC power to DC power for charging lithium or lead-acid batteries
This integration eliminates the need for separate inverter and charger units, saving space, weight, and cost — making it ideal for battery energy storage systems (BESS).
This energy storage inverter board is ideal for:
Portable Power Station Builders – Create your own solar generator for camping, RVs, or emergency backup. One board handles both charging and discharging.
Home Energy Storage Integrators – Build a battery energy storage system to store solar energy for nighttime use or backup during outages.
DIY Solar Enthusiasts – Perfect for off-grid cabins, workshops, or van conversions where space and efficiency are critical.
OEM/ODM Developers – Integrate this hybrid inverter board into your own product designs for energy storage applications.
| Application | How It Works |
|---|---|
| Portable Power Station | Charge from wall outlet (AC → DC) when at home; discharge to power devices (DC → AC) when off-grid. |
| Solar Energy Storage | Connect solar charge controller to battery; inverter board provides AC output while also enabling grid charging as backup. |
| RV or Van Conversion | One compact unit handles all power conversion needs — charge from shore power, run appliances from battery. |
| Home Backup System | Pair with lithium battery to create a simple UPS. When grid fails, inverter powers selected loads automatically. |
| Electric Vehicle Accessory | Use as a bidirectional power interface for EV auxiliary systems or vehicle-to-load (V2L) applications. |
| Feature | Standard Inverter Board | 700W Bidirectional Inverter Board |
|---|---|---|
| Function | DC → AC only | DC ⇄ AC (two-way) |
| Charging Capability | Requires separate charger | Built-in AC-DC charging |
| System Complexity | Two separate components | Single integrated board |
| Space Required | Larger footprint | Compact, saves space |
| Best For | Simple power conversion | Energy storage systems, portable power stations |
What’s the difference between bidirectional and hybrid inverter?
Bidirectional and hybrid are often used interchangeably. Our bidirectional inverter board refers specifically to the power conversion stage that handles both directions. A full hybrid inverter typically includes additional components like solar MPPT charging.
Can this board charge lithium batteries?
Yes. The 700W bidirectional inverter board is designed to safely charge both lithium-ion and lead-acid batteries. Proper charging parameters should be configured according to your battery specifications.
Do I need a separate solar charge controller?
If you’re using solar panels, you’ll still need a separate solar charge controller (MPPT or PWM) to regulate the solar input to your battery. This board handles the AC-DC conversion and inverter functions.
What’s the peak power rating?
This board provides 700W continuous power and can handle 1400W peak power for short durations — sufficient for startup surges from small motors, compressors, or pumps.
Can I use this for a home energy storage system?
Absolutely. This energy storage inverter is an excellent core component for small to medium home battery systems, especially when paired with lithium batteries and solar panels.
10+ Years of Manufacturing Experience – Factory-direct quality with proven reliability.
