Specifications
Last checked on 11 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 2 kWh per unit. Growatt says it can be expanded up to 8 kWh. |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | Lithium iron phosphate (LiFePO4) |
| 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. | Up to 6,000+ cycles |
| ExpansionExtra battery units that add storage to the same system. | Flexible expansion up to 8 kWh. Growatt does not list the module sizes on this page. |
| Power | |
| AC outputThe power it can deliver through its sockets or inverter, in watts. | Not stated on the product page. The NOAH 2000 is DC-coupled and feeds a micro-inverter, so the AC output depends on the micro-inverter you pair it with. |
| Efficiency and standby useLosses when charging, discharging and doing nothing. | MPPT efficiency 99%. Overall efficiency and standby use are not stated. |
| Solar | |
| Solar inputsThe number of panel strings it can track separately (MPPT) and the total DC power. | 2 MPPT inputs, 1,800 W of solar input in total, up to four solar modules |
| Grid connectionThe supply type it is built for. Check it matches your home's supply. | DC-coupled: it connects between the solar panels and a compatible micro-inverter. Growatt publishes a list of matching micro-inverters. |
| Connection and housing | |
| Dimensions (W × D × H)Check the space before you buy, including room around it for airflow and cables. | Not stated on the product page |
| WeightMatters for lifting, wall mounting and moving it. | Not stated on the product page |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP66 |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | -20 to 45 °C, with start-up support down to -30 °C |
| Battery heatingA built-in heater that lets the battery charge in cold weather. | Built-in heating film for continuous discharge at low temperature. It works while solar power is available. |
| ConnectivityHow you monitor and control it, usually through an app. | Not stated on the product page |
| Warranty | |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 10 years |
Compatible with
What Growatt says this product works with. Anything not listed here is not confirmed.

Rules where you live
Rules for plug-in batteries differ by country. In Great Britain, plug-in solar kits of up to 800 VA have been legal since 27 August 2026, but the rules exclude plug-in batteries. We could not confirm a UK version of this model.
Check the rules, incentives and tariffs for your own country in our country guides.
