Which plug-in solar kit with storage is suitable for tenants and homeowners?

A balcony power plant with storage combines solar modules, micro-inverters, and battery storage into a plug-and-play solution. It buffers solar energy generated during the day for evening use and is ideal for tenants on balconies as well as homeowners with dynamic tariffs like Tibber or aWATTar.

What is a balcony power plant with storage – and how does it work?

A balcony power plant with storage combines solar modules like the OSDA 450 Wp Full Black, a micro-inverter like the Deye SUN-M80G4-EU-Q0 with 800 W output power, and a battery storage system like the SunEnergyXT BK215 PLUS with 2.15 kWh capacity. The solar modules generate DC current, the inverter converts it into household current, and the storage system stores surpluses for evening use. Systems with IP65 protection and an operating temperature of -20 °C to +55 °C are weather-resistant.

• Solar modules generate DC power during the day.
• Inverters like Deye with 96.5% efficiency convert it into 230 V AC.
• Storage systems like SunEnergyXT 500 with 5.024 Wh nominal capacity buffer for nighttime use.
• Compatible with apps for monitoring and Home Assistant.

For whom is a balcony power plant with storage worthwhile – tenants or homeowners?

It is worthwhile for tenants with balcony areas of 2 m² or more and homeowners with dynamic tariffs. Tenants use non-drilling balcony mounts, while homeowners can scale up to 30 kWh for zero feed-in. Refurbished options like BK215 reduce the entry price.
