Power outages affect manufacturing facilities, warehouses, hospitals, supermarkets, schools and offices. When critical loads experience an power outage, they instantly lose power, come to a stop, and production comes to a standstill increasing risk to people and plant. High downtime costs and unreliable power grids are common-place in too many applications. Bidirectional Power Conversion Systems (PCS) resolve this issue by providing an “on-the-fly” transition from grid-connected mode to off-grid mode and vice versa, ensuring that an uninterrupted power supply is always available. Transitions from grid-connected to off-grid mode – and back to grid-connected mode again – occur in a matter of milliseconds, so that sensitive loads are not interrupted by any transition. Such capability is invaluable in the field of commercial backup power, where high reliability is associated with low costs, and business continuity.

What Is Seamless Grid-Tied to Off-Grid Switching in Bidirectional PCS?
Bidirectional PCS handles power flow in both directions between batteries and the AC grid or loads. Seamless switching ensures the system shifts to standalone off-grid mode instantly when the grid fails. You avoid any noticeable disruption to commercial operations. This feature directly solves your concern about maintaining continuous power during unexpected outages.
Ultra-Fast Transfer Time (≤10ms)
Average transfer time for the SRAM III is 10ms or less, non-disruptive to equipment being transfered. No resets or loss of data has been observed on any connected device, even while the transfer is under full load.
Grid-Forming Off-Grid Capability
The PCS regulates and supplies a stable AC voltage and frequency in off-grid mode. Independently of the grid, a long-term stable power supply can be generated in off-grid mode without an external grid reference.
Bidirectional Power Flow Flexibility
The Power is transferring continuously from the Grid to the Battery or from the Battery to the Load. Therefore it enables charging from cheap tariff periods in the Grid and discharging during expensive tariff periods or during grid failure.
Uninterrupted Power Supply During Grid Failures
Power grid failures are unpredictable events, and conventional inverters can cause momentary power outages that have costly effects. A bidirectional PCS identifies power grid failures instantaneously, switches to operating mode so quickly that there is no downtime to loads. Your critical load remains operational without interruption. The result is uncompromised operational reliability for today and tomorrow.
Instant Load Continuity
No power gaps ensure that loads receive continuous power. Data centers, servers, medical equipment and manufacturing plants can operate without any interruptions.
Black-Start Functionality
In emergency situations the system will automatically turn on and power the loads. The system powers up and brings loads on line from a fully discharged state of the batteries. Restores power to the loads even after complete discharge of the batteries or an extended period of power outage.
Inductive Load Stability
The PCS has the capability to handle high inrush current of motors and transformers without tripping out. It has an overload capacity of 110% for 10 cycles and 120% for 1 cycle.
Scalable and Reliable Commercial Backup Architecture
Systems like commercial buildings, offices, etc., require capacity that can scale as needed while providing the highest availability possible. The Bidirectional PCS system offers the option of parallel operation and redundancy. Even in the event that one module fails to operate, others will continue to supply power without interruption. Dependable performance is thereby ensured for even the medium to large systems.
Parallel Operation up to 4 Units
The system allows the connection of up to 4 units, so that power is adjusted to the needs of each installation without the need for complex redesigns. Expansion is also easier.
Redundancy for Fault Tolerance
REVERSO REDUNDANCY All the components that make up REVERSO are redundant, which means that in the unlikely event of failure of one single component, the system will continue to work. This means that the critical loads are always covered, regardless of any internal fault that may occur or maintenance operations.
High-Efficiency Energy Management
Controls that allow smart charging and discharging of battery systems, improved system efficiency resulting in less energy loss and lower operating expenditures.
Maximizing ROI with WonVolt Bidirectional PCS Solutions
Energy storage investments need to yield a direct financial return from cost savings and new revenue streams. Our energy storage solutions enable smooth switching between grid and battery power to provide reliable backup and peak shaving as well as maximum use of self-consumed solar power. Battery energy storage systems can store energy generated from the sun during periods of low tariffs and make it available during periods of high tariffs or during power outages. High efficiency and low maintenance also supports a quick payback on the investment. Check out our 100KW-1MW Battery Inverter for large-scale applications or the 100KW-630KW Battery Inverter for commercial uses.
Peak Shaving + Backup Synergy
Reduce demand charges by charging off peak and discharging during peak with energy stored in a battery ready for use. An efficient and cost effective option that adds value to your system.
Hybrid Solar + Storage Integration
Pair with your solar panels to increase self-consumption and minimize your connection to the grid. Excess energy generated during the day is stored in batteries for later use at night or during power outages.
Long-Term System Reliability
The Xerafina offers robust design and full system support to avert unplanned failures. Long term reliability of the system also provides stable returns on investment for the longest period of time and the lowest total cost of ownership.

FAQ
Q1: What is meant by Seamless Switching in the context of Commercial Backup Power?
A: Seamless Switching is defined as less than 10 milliseconds switching from Grid to Off-Grid during an outage. This enables Critical Loads to remain On and safe, thereby protecting sensitive equipment and operations.
Q2: How fast does the bidirectional PCS switch modes?
A: Transfer time is ≤10 ms at grid fault. This provides enough time for that no sensitive commercial loads are reset or lose information.
Q3: Is this product capable of handling large inductive loads when operating in off-grid mode?
A: The answer is yes. The PCS dealing with the excessive inductive loads is stable without causing the grid turning on and no restarts happen in this situation. The overload capacity of this product is 110% for 10 minutes and 120% for 1 minute.
