What are mobile storage units for balcony power plants?
Mobile storage units are portable energy storage devices with LiFePO4 battery technology that are compatible with balcony power plant systems. They use premium cells with a lifespan of over 10,000 cycles (approx. 30 years) and offer IP65 protection for outdoor use. Unlike stationary storage, they are transportable if required and enable decentralized energy supply – ideal for renters, camping, or flexible household solutions. DRBO Greenenergy is an authorized dealer of SunEnergyXT products and also offers refurbished storage solutions at up to 70% cheaper.
What are the practical applications of mobile storage units?
Mobile storage units enable diverse applications: in households for emergency power supply with UPS switching time under 10 milliseconds, for renter solutions without permits, in outdoor areas for camping with cooler supply, and in commercial settings for hardware stores and installers. Zero injection is compatible with Shelly Pro 3EM. Particularly attractive: the systems are modularly expandable and work with standard inverters such as Deye or APsystems.
How long do mobile storage units last in different applications?
The runtime depends on capacity and consumption. A 2 kWh system powers a 40W cooler for about 50 hours, a 200W refrigerator for about 10 hours. A 5 kWh system (SunEnergyXT 500) supplies typical household appliances for 20–30 hours. The LiFePO4 battery remains functional even at extreme temperatures (-20 °C to +55 °C) – with SunEnergyXT, it even features automatic battery heating below 0 °C. Regular charging by balcony power plant modules maximizes lifespan.
Which mobile storage units does DRBO Greenenergy specifically offer?
The flagship is the SunEnergyXT 500 series: The 500 head unit with 5,024 Wh (4.8 kWh usable), 800W on-grid power, and 2,400W off-grid/emergency power capacity costs 1,299 euros (RRP 1,699 euros). The PRO version with 2,400W on-grid power is priced at 1,349 euros. Additionally, there are expandable B500 modules (5 kWh) for 999 euros each – allowing for a total of up to 30 kWh. For smaller budgets: The older BK215 PLUS system (2.15 kWh) starts from 749 euros, plus refurbished Minjet storage units from 299 euros for beginners.

Are mobile storage units weather-resistant and suitable for balconies/gardens?
Yes, all SunEnergyXT models are certified with IP65 protection – waterproof and dustproof for outdoor use. The operating temperature ranges from -20 °C to +55 °C. The SunEnergyXT 500 series system even has an integrated aerosol fire suppression system and passive cooling without a fan, ideal for terraces, balconies, or camping. DRBO Greenenergy recommends additional protective covers for permanent outdoor installation.
How can mobile storage units be expanded and scaled?
The modular systems are highly expandable. The SunEnergyXT 500 series system can be combined with up to four additional B500 expansion batteries – for a total capacity of up to 30 kWh. The older BK215 PLUS system allows up to seven B215 PLUS expansion modules, for a total of 17.2 kWh. Expansion is possible at any time and does not require any electrician work. DRBO Greenenergy offers pre-configured complete sets such as the "Storage Trio" (6.45 kWh for 2,147 euros) or the "Storage Tower" (up to 8.6 kWh).

Can mobile storage units be used with dynamic electricity tariffs like Tibber or aWATTar?
Yes, absolutely. DRBO Greenenergy has specifically designed the "Dynamic Starter PLUS Set" (3,199 euros) for Tibber/aWATTar users. In combination with the Shelly Pro 3EM energy meter, the storage unit automatically optimizes itself to cheap electricity hours. The SunEnergyXT App (iOS & Android) with local API enables 1-second response times. This way, the storage unit is charged at night during favorable tariffs and used during the day.
Why are refurbished mobile storage units from DRBO the best choice?
Refurbished (overhauled) storage units offer identical quality to new goods at a fraction of the price – often 70% cost savings. The Minjet system from 299 euros retains the full manufacturer's warranty and withstands over 10,000 charging cycles. For renters, beginners, or testers, refurbished systems are perfect: less financial hurdles, more sustainable, and DRBO Greenenergy has a local German support team (Trustpilot 4.6/5). With 0% financing via Zinia up to 2,500 euros, entry is even possible from 29.90 euros monthly.
Which inverters are compatible with mobile storage units?
Most mobile storage units from DRBO work with hybrid or separately configurable inverters. The SunEnergyXT 500 series system has an integrated 800W (or 2,400W PRO) inverter. The older BK215 PLUS is compatible with the Deye SUN-M80G4-EU-Q0 (800W, 96.5% efficiency, 79.90 euros), APsystems EZ1-M (800W, 97.3% efficiency, 104.90 euros) and the bidirectional SunEnergyXT EV3600 (799 euros). All inverters use MPPT trackers for maximum efficiency.
How to choose the right mobile energy storage unit?
Criteria include: (1) Capacity as needed – renters start with 2 kWh, homeowners with 5+ kWh; (2) Compatibility with balcony power plant inverters; (3) Expandability for future growth; (4) Budget – refurbished from 299 euros or new from 749 euros; (5) Location (mobile vs. stationary).

In the event of a power outage, the storage unit immediately supplies critical loads (refrigerator, lighting, medical devices). The older BK215 PLUS system with EV3600 inverter offers similar security. DRBO Greenenergy recommends the "2Way Storage Tower PLUS Set" (8.6 kWh + EV3600) for maximum independence.
Does a mobile balcony power plant storage unit also fit rental apartments?
Ideal for renters. Mobile storage units do not require installation in walls or roofs – simply place them on the balcony, attach solar modules with tensioning straps, and plug the Schuko plug into the socket. DRBO Greenenergy has specially developed the "Renter Starter Set": a complete package with balcony power plant + storage, plug & play, no landlord's permission required (electricity meter should be reverse meter-capable). Additionally: with zero injection (Shelly Pro 3EM), electricity costs fall even further – perfect for rental apartments.
