Balcony Solar with Storage: Sunpura S2400 Powers the Energy Transition at Home
More and more households in Germany are embracing plug-and-play solar systems to generate and store their own electricity. One of the most compelling new solutions: the Sunpura S2400 balcony power station with integrated battery and compatible PV panels – a smart choice for both homeowners and renters looking to reduce their energy bills and increase independence.
Solar Power, Simplified: A Plug&Play Energy System for Everyday Living
With the Sunpura S2400, generating solar power is as easy as plugging in a device. This compact all-in-one system combines a 2.4 kWh battery, hybrid inverter, and intelligent energy control in a weatherproof housing. Pair it with Sunpura’s high-efficiency solar modules (e.g. 2×210Wp or 410Wp+), and you've got a complete micro energy system that feeds into your home grid via a standard power outlet – no rewiring or certified electrician required.
At a glance – Key features:
AC & DC Coupling: works with most microinverters and balcony PV systems
Smart App Control: track usage, automate charge/discharge cycles
Zero Feed-in Mode: 100% self-consumption compliant with German grid laws
Dynamic Tariff Optimization: charge at low rates, discharge during peak prices
Funding Opportunities: Support for Renters and Homeowners
While the Sunpura S2400 system isn’t yet part of KfW’s official funding programs, state-level subsidies for balcony solar kits are gaining momentum – with grants of €100 to €800 available depending on location and energy authority.
Currently fundable elements include:
Balcony solar installations up to 600W or 800W
Battery retrofits
Smart control systems for maximizing self-consumption
