The full 16 kWh LiFePO4 battery.
At a smarter price.
Same 314Ah LiFePO4 cells. Same 6U server rack form factor. Same 8,000-cycle endurance. The Standard edition strips away the premium surcharge — without stripping away what matters.
Everything you need.
Nothing you don’t.
The GP-SR1-JK314 delivers the same 16.08kWh of usable energy as its premium sibling — same cobalt-free 314Ah prismatic LiFePO4 cells, same 6U server rack chassis, same 8,000-cycle longevity. The difference? Standard-grade testing and a 5-10 year warranty that keep this 51.2V home energy storage battery at an accessible price.
- 16.08kWh usable energy — same capacity as the premium line
- Cobalt-free 314Ah prismatic LiFePO4 cells — 8,000+ cycle lifespan
- 51.2V nominal, 16S1P configuration — proven architecture
- Standard 6U server rack form factor (448 × 773 × 241 mm)
- Optional HSEV EVE314 cell upgrade available
A BMS that thinks
for itself.
The GP-JK200 battery management system (BMS) runs the show: 200A of managed throughput, per-cell voltage and temperature monitoring, and a built-in 2A active balancer that keeps all 16 cells in lockstep. Programmatic cell sorting before assembly means the pack starts balanced — the balancer just keeps it there.
- GP-JK200 200A BMS with per-cell voltage, current, and temperature monitoring
- Built-in 2A active balancer keeps all 16 cells perfectly synchronized
- Charge cutoff at 58.4V — prevents overvoltage before it starts
- Discharge cutoff at 40V — preserves cell health over thousands of cycles
- External 4A active balancer available as optional upgrade
It earns its name
before it leaves.
Every GP-SR1-JK314 undergoes a full charge-discharge cycling test before being cleared for shipment. Programmatic cell sorting ensures only matched cells make it into a pack. And lithium iron phosphate (LiFePO4) chemistry, cobalt-free and inherently stable, eliminates thermal runaway risk at the source.
- Full charge-discharge cycling test on every unit — not a sample, every single one
- Programmatic cell sorting — only matched cells make the cut
- Prismatic LiFePO4 chemistry — cobalt-free, no thermal runaway, no fire risk
- 5-10 year warranty backed by Gobel Power's Shenzhen engineering team
- 30-day free return to local warehouse

Start with 16kWh of home energy storage for a single-family home. Parallel up to 16 modules for a formidable 257kWh — enough for the largest residential estates, small businesses, or agricultural operations. Rack it in a standard 6U slot or stand it on the floor with the included wheels. Natural cooling means zero noise, wherever it lives.
- Up to 16 modules in parallel — 257kWh total system capacity
- Standard 19-inch 6U rack format — slides into any server cabinet
- Floor-mount option with built-in wheels — rack or freestanding, your call
- Natural convection cooling — no fans, no noise, no maintenance
- Indoor rated, operating from −20°C to +60°C discharge
One battery.
Every scenario.
From a single-family solar setup to a 16-module commercial array, the JK314 Standard fits the budget and the job.
The smart money
goes standard.
Same LiFePO4 cells. Same capacity. Same rack. Lower cost. The GP-SR1-JK314 Standard delivers where it counts for home solar storage and off-grid backup — and every unit is individually tested before it ships, because real-world performance is the only performance that matters.

The GP-SR1-JK314 Standard is built around multiple layers of protection:
- Built-in fire extinguisher — a first responder inside the enclosure
- GP-JK200 BMS with overcharge, over-discharge, short-circuit, and temperature protection
- Inherently safe LiFePO4 chemistry — no cobalt, and no thermal runaway risk like NMC chemistry
- 200A circuit breaker for a hard disconnect when it counts
- CE and UN38.3 certified
Together with a 300kgf cell compression fixture, a bad charge or a hot day never turns into a problem.
Up to 16 units in parallel on a single bus — roughly 257kWh of total storage. This lets you start with a single cabinet today and grow the system on your own timeline. Series connection is not supported; this is a 51.2V battery designed for parallel expansion.
The battery communicates over CAN, RS485, and RS232 ports and is compatible with nearly every major inverter on the market, including:
- Deye
- Victron
- Growatt
- Pylontech
- Megarevo
- GoodWe
- Luxpower
- And more — the compatibility list is continuously updated
Just select the matching protocol on the battery side and pair it with your inverter.
The battery is rated for 8,000 cycles at 80% depth of discharge. With one cycle per day, that is well over 20 years of daily use. The long life comes from the combination of built-in 2A active balancing (keeps all 16 cells perfectly in sync), the 300kgf cell compression fixture (stable, predictable aging), and natural cooling — no fans, no moving parts, no maintenance.
- Max charge current: 140A — fast top-ups when you need them
- Continuous discharge: 150A
- Peak discharge: 200A
For best long-term life, size your inverter and charge controller so typical operation stays comfortably below these limits.
The battery is CE certified and UN38.3 certified (the mandatory transport safety test for lithium batteries). Certificates can be provided on request — just contact us before ordering if you need documentation for your installer, permitting office, or logistics provider.
This item is stocked in our European warehouse (EU stock). That means no slow boat from Asia, no customs surprises, and no import taxes — the battery ships from inside Europe, lands fast, and just works. Accessories and spare parts can be shipped via UPS/DHL.
