Growatt Hope 5.0L-B1 51.2V 5.1kWh Energy Storage Lithium Battery

Growatt HOPE 5.0L-B1 5.12kWh LiFePO4 Battery

The Growatt HOPE 5.0L-B1 is a 51.2V lithium iron phosphate (LiFePO4) battery designed for residential solar energy storage. Its compact design, integrated battery management system (BMS) and expandable capacity make it suitable for compatible low-voltage inverter systems.

Specifications

Features
• Integrated BMS for battery monitoring and protection
• Battery status display and on/off control
• Supports expansion with additional compatible HOPE 5.0L-B1 modules
• Compact design for indoor installation

Expansion: parallel connection of up to 48 packs — capacity grows with the needs of the installation. Capacity is matched to the daily energy consumption and the goal of the investment: to increase self-consumption, an energy storage battery covering the evening load is usually enough, while real backup power calls for more capacity and power. 

• Which inverters does the Growatt HOPE 5.0L-B1 work with?

  It is a low-voltage (LV) energy storage battery, designed to work with Growatt SPF off-grid inverters Such (SFF6000ES, SPF6000G2) and single-phase Growatt SPH hybrid inverters. The battery’s voltage class must match the inverter.

  What is the capacity and can I expand it?

  This model offers 5.1 kWh of capacity. Expansion: parallel connection of up to 48 packs — capacity grows with the needs of the installation.

  What cell chemistry and cycle life does the Growatt HOPE 5.0L-B1 offer?

  LiFePO4 cells, with a cycle life of around >6000 (25°C, 0.2C) cycles and a depth of discharge of 98%. A safe and durable cell technology.

  Does the Growatt HOPE 5.0L-B1 provide backup power?

  Yes — combined with a hybrid inverter, the energy storage battery keeps selected circuits running during a grid outage (the inverter’s backup/EPS function).

  Where can I install the HOPE 5.0L-B1?

  The ingress protection rating is IP20. Installation should be carried out by a qualified installer according to the manual; pay attention to the operating temperature range and ventilation.

  What warranty does the Growatt HOPE 5.0L-B1 carry?

  The product is covered by warranty of 5 years, per the manufacturer terms.

  How do I monitor the state of charge of the HOPE 5.0L-B1?

  Battery status (SOC), charging and discharging are all visible in the ShinePhone app and the ShineServer portal — through the inverter the energy storage battery is connected to.

  What is the difference between a low-voltage (LV) and a high-voltage (HV) battery?

  LV batteries (around 48-51 V) work with off-grid inverters and some hybrid inverters; HV batteries (hundreds of volts) work with three-phase hybrid inverters. The battery must match the inverter’s voltage class — otherwise the system will not work.
