The flagship.
32 kilowatt-hours. One unit.
A 628Ah LiFePO4 floor-standing battery with a 300A BMS, WiFi-connected Gobel VRM monitoring, and 8,000-cycle endurance — engineered for homes and businesses that need serious storage without serious complexity.
Twice the capacity
of a standard rack battery.
Most server rack batteries deliver 5–16kWh. The GP-PB5-32K packs 32.15kWh into a single floor-standing enclosure (910 × 764 × 315mm). A 16S2P configuration pairs premium 314Ah cells to produce 628Ah at 51.2V — enough for a full day of whole-home consumption, from one unit. No multi-module wiring. No rack assembly. Just massive, concentrated storage.
- 32.15kWh usable energy — 628Ah at 51.2V from a single enclosure
- 16S2P configuration with premium 314Ah prismatic LiFePO4 cells
- 910 × 764 × 315mm — dense enough to deliver 2× standard rack capacity
- 300A max charge and 300A max discharge — high-power handling for demanding loads
- 95% round-trip efficiency — more of your solar ends up where it belongs
300 amps of managed
intelligence.
The PC-16S300A BMS doesn't just watch — it actively governs 300A of charge and discharge current with cell-level precision. Over-voltage, under-voltage, over-current, short-circuit, and thermal protection run continuously across all 32 cells (16S2P). Built-in active cell balancing ensures every cell ages together, keeping your 32.15kWh fully available for years.
- PC-16S300A intelligent BMS — 300A charge/discharge, cell-level monitoring
- Charge cutoff at 58.4V, discharge cutoff at 40V — wide operating window
- Built-in active cell balancing across all 32 cells in the 16S2P configuration
- Over-voltage, under-voltage, over-current, short-circuit, and thermal protection
- IP20 rated for indoor installation — natural cooling, no fans, no noise
8,000 cycles.
10-year warranty.
Cycle it every day for 22 years — that's what 8,000 cycles means in the real world. Premium 314Ah LiFePO4 cells, a conservative 58.4V charge ceiling, and active balancing combine to deliver the longest service life in the Gobel lineup. A 10-year warranty and 10-year design life back that promise with certainty, not marketing.
- Up to 8,000 cycles — the highest endurance in the Gobel Power lineup
- 10-year warranty and 10-year design life — matched coverage
- Premium 314Ah LiFePO4 cells with industry-leading cycle stability
- Active cell balancing preserves capacity uniformity across all 32 cells
- Operating from −20°C to +60°C, up to 4,000m elevation
32 kilowatt-hours,
visible from anywhere.
Built-in WiFi connects the GP-PB5-32K directly to the Gobel VRM platform. Check state of charge, state of health, power flow, and per-cell voltages from your phone — whether you're in the next room or the next country. RS485, CAN, and RS232 ports provide wired fallback for local integration and inverter communication.
- Built-in WiFi module — connects directly to Gobel VRM cloud platform
- Real-time SOC, SOH, and power flow tracking on any mobile device
- RS485 · RS232 · CAN ports for universal inverter compatibility
- Compatible with Home Assistant and ioBroker for smart home integration
- Over-the-air monitoring — no on-site visit needed for status checks
Start at 32kWh.
Grow past 480.
A single GP-PB5-32K already handles whole-home storage. But if your needs grow, parallel up to 15 units for a staggering 482.25kWh. Auto-addressing makes expansion plug-and-play — connect the communication cables, and the BMS sorts out the rest. No manual DIP switch configuration, no commissioning headaches.
- Up to 15 units in parallel — 482.25kWh maximum system capacity
- Auto-addressing for parallel connections — no manual DIP switch configuration
- Floor-standing design — line them up, no rack infrastructure required
- Each unit independently managed with its own BMS and WiFi module
- From a single-family home to a commercial microgrid — one scalable platform
One platform.
Every scale of storage.
From a single-family home to a 15-unit commercial array, the GP-PB5-32K is the same battery, scaled to fit.
One battery.
One decade. Zero regrets.
The GP-PB5-32K is the flagship for a reason: 32.15kWh in one enclosure, 8,000-cycle endurance, a 300A BMS, WiFi-connected Gobel VRM monitoring, and auto-addressing parallel expansion to 482kWh. For homes and businesses that measure storage in decades, not years.
