Every GP-SR1-PC314-Standard starts with brand-new HSEV-grade 314Ah prismatic LiFePO4 cells — never recycled, never B-stock.
Programmatic cell sorting matters: before assembly, every cell is measured and matched so each 16S1P module ships with uniform cell voltages and internal resistance. Consistent cells deliver power more efficiently, age evenly, and avoid the premature failures that mixed cells cause.
A ~300 kgf compression system then holds every cell in place, reducing mechanical stress across thousands of charge-discharge cycles.
Verified specs: 51.2V nominal / 314Ah / 16kWh total energy, 8,000+ cycles at 80% DoD, max 140A charge / 200A discharge (cut-off protection at 55.2V charge / 46V discharge).
Yes — this is EU stock. The battery is sitting in our European warehouse, tested and ready to ship:
- Delivery in 7–15 days from the local warehouse — no 60-day ocean freight from China
- No customs clearance delays, no import duties — tax is already handled; nothing extra to pay on arrival
- 30 days free return to the local warehouse for peace of mind
That means your home solar battery storage project moves forward while everyone else is still tracking a container. (Accessories and spare parts ship via UPS/DHL; note the same model ships from China in 50–60 days when ordered from the China warehouse.)
Warranty:
- 8-year manufacturer warranty on the GP-SR1-PC314-Standard (Standard-grade coverage; Premium models carry up to 10 years)
- 30 days free return to the local warehouse
Safety: LiFePO4 chemistry is inherently stable — the cobalt-free LiFePO4 cathode has no thermal runaway risk (unlike NMC), plus:
- PC200 200A professional ESS BMS with overcharge, over-discharge, short-circuit, and temperature protection
- 250A front-panel DC circuit breaker — hard disconnect without opening the chassis
- Certified to CE, UN38.3, and IEC 62619
Cycle it once a day at 80% depth of discharge and it keeps going for over 20 years — a home energy storage battery that outlasts the solar panels.
Inverter compatibility: the PC200 200A BMS provides RS485, CAN bus, and RS232 wired ports — protocols proven across every major inverter brand:
- Deye, Victron, Growatt, GoodWe, Luxpower, Sol-Ark, SMA, Schneider, Solis and more
- No custom firmware or protocol converters needed
Monitoring options:
- Bluetooth wireless — check individual cell voltages and pack SOC from your phone via the Gobel Power app
- Home Assistant, Solar Assistant, and Victron VRM integration for whole-system energy monitoring
- Wired RS485 / RS232 / CAN feeds battery data to your inverter or energy dashboard
No lithium communication port on your inverter? Set it manually in lead-acid mode: max charge voltage 55.2V, max charge current 140A, max discharge current 200A.
Yes — parallel up to 63 units, scaling from 16kWh to over 1MWh of LiFePO4 energy storage:
- Auto-addressing protocol removes DIP-switch guesswork — plug in a new pack and the system configures itself
- Proven CAN bus and RS485 protocols keep every pack synchronized with your inverter
- For mixed-age banks, do a full charge to 100% at least monthly to keep SOC readings aligned across packs
Installation:
- Standard 6U 19-inch rack-mount form factor — fits any server cabinet or open rack (482.6 × 771.5 × 241 mm verified footprint)
- Integrated chassis rolling wheels — roll it into place, no forklift required
- Natural cooling — silent, fanless operation
- Discharge temperature -30°C to +60°C
Applications: home solar battery storage, off-grid energy storage, commercial & industrial ESS, telecom backup power, microgrid battery storage, and UPS critical-load backup.
