A: Yes. The system features a modular N+1 redundant design. It can operate stably with a single 1800W rectifier module (up to 30A @ 48V) and allows hot-plugging a second module at any time to double capacity to 3600W (60A) without shutting down connected loads.
A: LLVD (Low Voltage Load Disconnect) cuts power to non-critical loads first during extended AC outages to prolong backup time for essential devices. LVBD (Low Voltage Battery Disconnect) disconnects the battery pack entirely when reaching the critical cutoff voltage to protect batteries from deep discharge damage.
A: Yes. The central controller integrates Fast Ethernet and RS485 ports supporting standard SNMP (v1/v2c/v3) and Web browser access for remote monitoring of voltage, current, battery SOC, and instant alarm traps.
A: Absolutely. The controller supports pre-set charging curves for AGM/VRLA lead-acid, Gel, and LiFePO4 telecom lithium batteries, with customizable float/boost voltage thresholds and temperature compensation.
A: Standard evaluation samples are usually ready to ship within 3–5 working days. Bulk custom orders (50–500 units) typically have a production lead time of 15–20 business days.
