| Advantage | Benefit for Your Application |
|---|---|
| ✅ True Bidirectional Power Flow | One converter handles both charging and discharging between the 30~100Vdc LiFePO4 battery side and the 200~750Vdc DC bus - no separate charge/discharge hardware needed. |
| ✅ 20kW per Module, Parallel Expansion | Scale from 20kW to hundreds of kW by paralleling modules - build exactly the power stage your storage or microgrid project needs. |
| ✅ High Efficiency, Low Ripple | ≥95% efficiency with ≤±5% steady-current accuracy, <5% current ripple and <2% voltage ripple keeps battery cycling clean and cool. |
| ✅ Liquid-Cooled, Rack-Dense | Liquid cooling in a 220 × 82 × 440mm, 6kg rack-style chassis delivers 20kW in a footprint that slides into ESS containers and cabinets. |
| ✅ Grid-Ready Three-Phase Input | 380/480Vac three-phase input with PF ≥ 0.99, 45~65Hz window and <30W standby makes utility and C&I integration straightforward. |
| ✅ RS485 / CAN Communication | RS485 (CAN port on terminal block) ties each module into BMS and system SCADA for monitoring, current sharing and coordinated control. |

Q1. What does "bidirectional" mean in practice?
A: The same 20kW power stage transfers energy in both directions - charging the 30~100Vdc LiFePO4 battery pack from the 200~750Vdc DC bus, and discharging the pack back to the bus. Mode switching is managed by the control system over RS485/CAN.
Q2. How do I scale beyond 20kW?
A: The module is designed for parallel expansion. Multiple BA100-20000 units can be paralleled on the DC bus and battery side to reach cabinet-level power; contact us for current-sharing and communication wiring guidance.
Q3. Which battery chemistries are supported?
A: The battery side is rated for 30~100Vdc with a 60Vdc nominal point, targeting LiFePO4 packs (typically 15~25s configurations). Confirm your pack voltage window with our engineers before ordering.
Q4. What are the output quality specs?
A: Steady-current accuracy ≤ ±5%, current ripple < 5%, voltage ripple < 2%, efficiency ≥ 95%, and standby consumption below 30W when the module is dormant at Vbat = 100Vdc.
Q5. How is the module cooled and protected?
A: Liquid cooling handles the 20kW thermal load in the compact 220 × 82 × 440mm chassis (approx. 6kg), and the unit is rated IP20 for installation inside cabinets and ESS containers.
Q6. What grid input does it accept?
A: Three-phase 380Vac / 480Vac, 45~65Hz, input current below 40A with power factor ≥ 0.99 (full-load range 323~530Vac) - suitable for standard C&I low-voltage distribution.
