SunLit balcony power plant set BK215 with 2.15 kWh LFP storage – the product for real independence

0% marketing speak, 100% facts. If you want to cut your electricity consumption without removing roof tiles or hiring tradespeople, you need a solution you can plug in yourself. This is exactly where SunLit comes in with its balcony power plant set BK215 : 760 Wp panel output, 2.15 kWh LFP storage, modularly expandable, and an inverter that even powers your wallbox. Let’s go.

1. Why SunLit Solar? – An overview of SunLit products

SunLit has a clear positioning: plug-and-play solar for rented and owner-occupied apartments with limited space. The product line ranges from the small SunLit Starter Set (a compact 380 Wp panel plus mini inverter) to the powerful EV3600 off-grid storage unit for self-sufficient applications. The key unique selling point is the LFP storage: higher cycle life, no fear of fire, suitable for winter. For every use case – balcony, carport, garden shed – SunLit has a suitable product in its range.

2. Balcony power plant instead of a solar system – the pragmatic solution

A classic solar system on the roof squeezes out the last few percent of efficiency, but requires permits, structural calculations and installers. A balcony power plant (BPP), by contrast, is simply plugged into a Schuko socket with a maximum of 800 W. Two modules of 500 Wp each together deliver around 1000 Wp – enough to cover the fridge, router and the like during the day. Several balcony power plants can be cascaded as long as grid regulations are complied with. Electricity you don’t use immediately ends up in the SunLit storage instead of the grid – that saves real kilowatt-hours.

3. The SunLit BK215 Starter Set: 880 Wp module output, 2150 Wh battery storage

The BK215 is SunLit’s current top set: two bifacial 440 Wp modules (total: 880Wp) plus 2.15 kWh of battery storage in a stackable LFP housing. The unit already includes the micro inverter, DC switch and app-controlled energy management. If you need more capacity, you can connect up to three B215-modules and thus reach 8.6 kWh. This lets you cook in the evening even in autumn, while energy collected during the day fills the storage.

Technical specifications

• 2150 Wh (2150 Wh) usable

• 760 Wp module output

• IP65 housing, indoor/outdoor

• OTA updates for new grid regulations

4. EV3600 inverter from Deye and intelligent LFP storage

The integrated inverter comes from Deye, runs as an OEM version at SunLit and is internally called EV3600. It is bidirectional: it converts PV DC into grid AC and, conversely, can draw battery DC when you run an off-grid system or activate “Backup power” via the app. 2.4 kW continuous output, 3.6 kW peak for short load spikes – enough for a kettle or air conditioner. The LFP chemistry (LiFePO₄) delivers over 6,000 cycles, after which 80% capacity is still available. With favourable tariffs, you can charge the storage from the grid at night and use timed feed-in in the morning to push breakfast electricity costs down to 0 ct.

5. Energy management, wallbox integration and expansions

• Wallbox: Via the special 3.6 kW AC port, the EV3600 couples directly to the SunLit Aurora wallbox; charge your car when the modules deliver surplus – no expensive home energy manager needed.

• Expansion with B215: Each additional battery increases storage capacity by a further 2.15 kWh, fully backward compatible.

• EV3600 stand-alone: If you already own modules, you can buy just the off-grid storage unit and upgrade an existing BPP.

• App & API: Real-time data, push alert in case of grid failure, schedules for low tariffs.

• Safety: LFP storage units de facto don’t burn, the inverter has AFCI and RCD protection, CE and VDE certification.

All this makes the system not only powerful but also pragmatic: screw it on, plug it in, done.

6. Conclusion – control your own energy with SunLit Solar

Anyone looking for results rather than buzzwords inevitably ends up with SunLit. The SunLit BK215 Set covers typical base loads, stores surplus in the SunLit storage and expands modularly as needed – from the simple Starter Set to a self-sufficient off-grid solution. The combination of LFP storage, , Deye inverter and well-thought-out monitoring delivers tangible benefits: long service life, safe technology and finally control over your own energy. In short: SunLit Solar is currently one of the few plug-and-play solutions that truly and cleanly bridges the gap between a balcony power plant and home storage.
