Q1. The title says "3.2V/280Ah" — is this really a 3.2V battery?
A: No. 3.2V/280Ah is the LiFePO4 cell specification. Inside the cabinet, 16 cells are connected in series (16S1P) to form a 51.2V rated battery system with 280Ah capacity, operating between 40V and 58.4V (charge voltage 58.4V, discharge cut-off 40V).
Q2. How much energy does it actually store?
A: 51.2V × 280Ah = 14,336Wh ≈ 14.3kWh (the product name BA-ESS-14.336KWH reflects this). Note the spec table lists "14.366KWh" — the mathematically consistent figure for 51.2V/280Ah is 14.336kWh; request the datasheet to confirm the exact naming before ordering.
Q3. Can several units work together?
A: Yes. The system is parallel-ready: the monitoring device acts as the host and polls data by address, with the address setting range 2–15. In parallel operation, the two RS485 interfaces are daisy-linked with standard network cables — see the parallel connection diagram above.
Q4. What charge/discharge currents does it support?
A: Standard charging and discharging current is 100A, with up to 150A max continuous discharge and internal resistance ≤0.21mΩ. Cycle life is 6,000 cycles at 0.5C charge / 0.5C discharge to rated capacity.
Q5. How do I monitor and control it?
A: Through RS485, CAN or RS232, plus a DIP address switch and DI/DO terminals. Locally, the LCD panel (MENU / Enter / Down / ESC keys) and ON/OFF button provide status readout and settings, with ALM / RUN / SOC indicator lights and two 5V USB ports on board.
Q6. How is it shipped and how easy is it to move?
A: Each unit ships as a single item in a plywood crate (package size 550 × 270 × 728cm, gross weight 120kg). The cabinet itself rides on four casters, so despite its 120±1kg weight it can be repositioned by one person without a forklift.
