Deye WD-G12100 / DEYE-WD-G12200

Deye's small-format 12.8 V battery: 100 Ah of prismatic LiFePO4 cells, 1.28 kWh, and series or parallel flexibility up to four in series and ten in parallel.

Models Covered: DEYE-WD-G12100, DEYE-WD-G12200

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: Small systems deserve real LiFePO4 engineering too: the Deye WD-G12100 packs 100 Ah - 1.28 kWh - into an 11 kg, 310 x 298 x 160 mm case built on prismatic cells in a 1P4S configuration. It sustains 100 A of charge and discharge with a 200 A peak, leaving headroom for inverter surges in compact installations. Flexibility is the point: up to four units wire in series to build a 51.2 V bank, up to ten run in parallel, and RS485 communication plus an LED keep state of charge visible. The recommended depth of discharge is 80%, cycle life exceeds 6,000 cycles to 70% capacity, and the operating window spans 11.2-14.6 V. Charging is specified from 0 to 55 degrees Celsius and discharging from -20 to 55, at altitudes up to 2,000 m and humidity to 95%. Floor and stack mounting keep placement simple, and the pack is certified to UN38.3 with an MSDS available.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in Yemen that is Public Electricity Corporation (PEC), Ministry of Electricity and Energy. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Key Features & Technical Highlights

  • A 12 V building block: 12.8 V nominal and 100 Ah - 1.28 kWh - from prismatic LiFePO4 cells in a 1P4S pack.
  • Just 11 kg: A 310 x 298 x 160 mm case light enough for one person to carry and position.
  • 200 A peak headroom: 100 A of continuous charge and discharge, with a 200 A peak for surge moments.
  • Series to 51.2 V: Four units in series form a 51.2 V nominal system; up to ten units run in parallel.
  • 6,000-cycle endurance: Rated beyond 6,000 cycles to 70% capacity at the recommended 80% depth of discharge.
  • RS485 plus LED: RS485 communication with LED indication of state of charge and operation.
  • Double the amp-hours: 200 Ah and 2.56 kWh at 12.8 V nominal from a 2P4S prismatic LiFePO4 configuration.
  • 300 A peak muscle: 200 A of continuous charge and discharge, with 300 A available at peak.
  • Series and parallel ready: Four in series reach 51.2 V nominal; up to ten units combine in parallel.
  • Long-cycle chemistry: More than 6,000 cycles to 70% capacity at the recommended 80% depth of discharge.
  • Manageable 21 kg format: A 471 x 348 x 160 mm case that floor- or stack-mounts without lifting gear.
  • Simple integration: RS485 communication and LED state-of-charge display, certified to UN38.3 with MSDS.

Frequently Asked Questions

What can I build with WD-G12100 batteries?

Anything from a single 12.8 V supply to a 51.2 V bank: up to four units connect in series and up to ten in parallel.

What is the peak current of the WD-G12100?

200 A, on top of a 100 A continuous charge and discharge rating.

How heavy is the WD-G12100?

11 kg, in a 310 x 298 x 160 mm case - a genuinely one-person module.

What cells does the WD-G12100 use?

Prismatic LiFePO4 cells in a 1P4S layout, rated for more than 6,000 cycles to 70% remaining capacity.

What environmental limits apply to the WD-G12100?

Charging from 0 to 55 degrees Celsius, discharge from -20 to 55, humidity to 95%, storage at 0-35 and altitude below 2,000 m; the IP20 case needs a dry, protected spot.

How much energy does the WD-G12200 store?

2.56 kWh - 200 Ah at 12.8 V nominal, within an 11.2-14.6 V operating window.

What surge current can the WD-G12200 supply?

A 300 A peak, above its 200 A continuous rating in both directions.

Can WD-G12200 units form a 48 V-class system?

Yes - four in series produce a 51.2 V nominal bank, and up to ten units may be paralleled for capacity.

What separates the WD-G12200 from the WD-G12100?

Capacity and current: 200 Ah and 2.56 kWh versus 100 Ah and 1.28 kWh, with 200 A continuous and 300 A peak versus 100 A and 200 A; the larger pack weighs 21 kg instead of 11 kg.

How should the WD-G12200 be stored and sited?

Indoors on a floor or in a stack, stored at 0-35 degrees Celsius, at up to 95% humidity and below 2,000 m altitude.
