Growatt NOAH2000 Low Voltage Energy Storage for Balcony
One of the most popular and best solutions for balcony solar panel system installations in Germany
Growatt Noah2000 Balcony Solar Power Station – 2kWh Energy Storage Unit
The Growatt Noah2000 is a compact balcony solar power station and energy storage unit designed for plug-and-play photovoltaic systems commonly used in European residential environments. With a usable capacity of 2,048 Wh, expandable up to 8,192 Wh, the Noah2000 enables efficient self-consumption of balcony-generated solar energy while maintaining the flexibility of a portable power station.
Engineered specifically for balcony PV (Balkonkraftwerk) applications, the Noah2000 integrates storage, PV charge control, and microinverter interface in a single unit. It allows homeowners and installers to add battery storage to existing or new balcony solar systems without structural changes, grid approval procedures, or complex inverter installations.
System Concept and Intended Use
Balcony PV Energy Storage
The Noah2000 is designed to store surplus energy generated by 300–900 W balcony solar systems, typically installed on balconies, terraces, façades, fences, or small rooftops. During daylight hours, excess PV energy is stored in the internal battery and later used for household loads during evening or night-time hours, increasing on-site self-consumption and reducing grid dependency.
Portable Power Station Functionality
In addition to fixed balcony PV operation, the Noah2000 functions as a portable power station. It can be disconnected from the balcony system and used as a mobile energy source for backup power, outdoor applications, workshops, garden houses, or temporary off-grid use.
This dual-use concept makes the Noah2000 suitable for renters, apartment owners, and users who require both stationary storage and mobile energy availability.
Energy Storage Architecture
Battery Technology
The Noah2000 uses LFP (Lithium Iron Phosphate) battery chemistry, selected for its thermal stability, safety, and long service life. LFP cells provide consistent performance across a wide temperature range and are particularly suitable for daily charge/discharge cycles typical of balcony PV systems.
-
Usable capacity: 2,048 Wh
-
Expandable capacity: up to 8,192 Wh
-
Cycle life: >6,000 cycles
This ensures long-term reliability even with continuous daily operation.
Battery Management System (BMS)
An integrated BMS manages charging, discharging, temperature control, and cell balancing. Protection functions include over-voltage, under-voltage, over-current, short-circuit, and thermal protection, ensuring safe operation under all supported conditions.
PV Input and MPPT Configuration
Dual Independent MPPT Inputs
The Noah2000 features two independent MPPT inputs, each supporting up to 900 W PV input power. This allows flexible connection of balcony PV modules with different orientations or exposure conditions.
-
Optimized for typical balcony PV module layouts
-
Independent tracking improves yield under partial shading
-
No external charge controller required
The dual-MPPT design ensures efficient energy harvesting from compact PV arrays commonly used in balcony installations.

Plug-and-Play Design
The Noah2000 is designed for fast, non-invasive installation. No modification of household wiring, no hybrid inverter, and no grid operator approval are required.
-
H4 connectors for PV input
-
Predefined interfaces for microinverter output
-
Simple positioning indoors or outdoors
Installation can be completed within minutes, making it ideal for both professional installers and technically experienced end users.
Placement Flexibility
Thanks to its compact form factor and robust enclosure, the Noah2000 can be installed:
-
On balconies
-
On terraces
-
In storage rooms or utility spaces
-
In garden houses or garages
Environmental Protection and Operating Conditions
IP66 Enclosure
The Noah2000 features an IP66-rated enclosure, providing protection against dust, rain, and water jets. This makes it suitable for outdoor balcony environments and exposed locations.
Cold-Start Capability
The system supports cold-start operation down to –30 °C, ensuring reliable performance during European winter conditions.

Power Output and Applications
Household Loads
With its 2kWh storage capacity, the Noah2000 can supply:
-
Routers and networking equipment
-
Lighting circuits
-
Laptops and mobile devices
-
Small household appliances
-

Self-Consumption Optimization
By storing solar energy during the day and releasing it during evening hours, the Noah2000 significantly improves the economic efficiency of balcony PV systems where direct daytime consumption is limited.
Expandability and System Scaling
The modular design allows the Noah2000 to be expanded with additional battery units, increasing total capacity up to 8,192 Wh. This enables users to adapt storage size to seasonal demand or future energy requirements without replacing the core system.
Compliance and Market Suitability
The Noah2000 is designed for the European residential solar market, particularly countries with strong balcony PV adoption such as Germany, Austria, Switzerland, the Netherlands, and Poland. Its plug-and-play architecture aligns with regulatory frameworks where small PV systems are allowed without extensive approval procedures.
