Growatt Hope 5.5L-A1 5.5kWh Lithium Solar Battery

Description

Growatt Hope 5.5L-A1 5.5kWh Lithium Solar Battery

Designed for modern homes, corporate office suites, healthcare clinics, and telecom server cabinets across Bangladesh requiring uninterrupted power during frequent load-shedding, the Growatt Hope 5.5L-A1 represents Growatt’s dedicated high-density residential and light-commercial low-voltage energy storage platform. It replaces heavy, short-lived 48V lead-acid and tubular battery banks with a compact, rack-ready Lithium Iron Phosphate solution requiring zero water replenishment and emitting no harmful acid fumes.

The battery module utilizes Grade-A LiFePO4 prismatic cells operating on a standard 51.2V nominal low-voltage DC bus (operating range 40.0V to 58.4V DC). Delivering 5.5 kWh of nominal capacity and 5.12 kWh of usable energy at 93% DoD, it achieves over 6,000 deep cycles, translating to more than 10 to 15 years of daily cycling service without the rapid capacity fade, plate sulfation, or thermal runaway risks associated with traditional chemistries.

Safety and cell longevity are governed by an integrated multi-stage smart Battery Management System (BMS) that continuously monitors cell-level voltages, currents, and internal temperature profiles. The BMS provides automatic protection against over-voltage, under-voltage, charging overcurrent, discharging overcurrent, short circuits, and thermal extremes. With dual CAN and RS485 communication ports, the battery syncs telemetry and charge parameters with Growatt off-grid and hybrid inverters (such as the SPF 3500–5000ES and SPH series) as well as compatible 48V inverters. For growing power needs, the system supports parallel clustering of up to 12 modules, scaling storage from 5.5 kWh up to an enterprise-grade 66 kWh bank.

Constructed inside a compact, powder-coated SPCC steel chassis ($440 \times 540 \times 130.5\text{ mm}$, 45 kg), the unit fits seamlessly into standard 19-inch server racks, battery cabinets, or stacked bracket installations. Front-facing LED status indicators display real-time State of Charge (SoC), running state, and active alarms, accompanied by dual integrated carry handles and heavy-duty screw terminals for secure DC busbar cabling.
