Specifications

Last checked on 11 November 2026. The grey text under each name explains what the value means.

SpecificationValue
Storage
CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later.10.24 kWh nominal per module (51.2 V, 200 Ah)
Usable capacityThe part of the stored energy you can actually use. It is lower than the nominal capacity.9.728 kWh per module
Depth of dischargeHow much of the battery can be emptied without harming it. 90% means 10% is kept in reserve.95%
Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat.Lithium iron phosphate (LiFePO4, LFP)
Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity.8,000 cycles or more (0.2C charge and discharge, 25 °C, 95% depth of discharge, 70% end of life)
ExpansionExtra battery units that add storage to the same system.Up to 50 units in parallel (the product page gives a range of 10.24 kWh to 512 kWh)
Power
Charge and discharge powerHow fast the battery can take in and give out energy. It sets how many devices it can serve at once.Recommended 5.12 kW (0.5C, 100 A); maximum discharge 10.24 kW (1C, 200 A). Operating voltage 44.8 to 57.6 V
Peak outputA short burst above the continuous rating, for example to start a motor. It cannot be held.Peak discharge current 300 A for 2 minutes at 25 °C
Backup in a power cutWhether it can keep selected circuits running during a grid outage.Not stated: backup comes from the inverter, which the datasheet does not describe
Solar
Solar inverterTurns the DC power from solar panels into AC for the home. Built in means no separate solar inverter is needed.None: this is the battery only. The datasheet lists inverter brands it works with (see 'Compatible with')
Connection and housing
Grid connectionThe supply type it is built for. Check it matches your home's supply.Not applicable: the battery connects to an inverter (nominal 51.2 V DC)
Dimensions (W × D × H)Check the space before you buy, including room around it for airflow and cables.710 × 165 × 730 mm
WeightMatters for lifting, wall mounting and moving it.96.12 kg net
Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance.IP65, anti-corrosion class C5-M; built-in aerosol fire extinguisher; floor or wall mounting
Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance.Charge 0 to 55 °C (-20 to 55 °C optional); discharge -20 to 55 °C
ConnectivityHow you monitor and control it, usually through an app.CAN and RS485 to the inverter; WiFi and app for the user
CertificationsSafety and grid standards the maker says the product meets.UN38.3, CE-EMC, IEC 62619, IEC 62040, CE-RED, CEC, CEI 0-21
Warranty
WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ.10 years. The datasheet refers to the Dyness warranty letter for the conditions, which we have not read

Mounting
Floor-mounted or wall-mounted.

Rules where you live

An installed battery normally needs a qualified electrician, and in many countries you must also tell your grid operator, especially if it can export. This is not a plug-in battery. Rules, incentives and tax treatment differ by country: see our country guides for what applies where you live.

Strengths and things to check

Strengths

  • Slim: 165 mm deep, for wall or floor mounting
  • IP65 with a built-in aerosol fire extinguisher
  • 8,000-cycle rating under stated test conditions
  • 10.24 kWh per module, up to 50 units in parallel
  • 10-year warranty

Worth checking before you buy

  • A battery only: you need a compatible inverter
  • Heavy: 96.12 kg per module
  • Backup and efficiency figures are not on the datasheet
  • The inverter list ends with 'etc.', so check your exact model
