Balcony Power Plant with Storage 800W - Anker Solix Solarbank 3 Pro - 450W Bifacial Solar Panels

Balcony Power Plant 890 Wp – 2 Modules + Anker SOLIX Solarbank 3 Pro

Two bifacial JA Solar 445 Wp high-performance modules feed up to 890 Wp DC power during the day, of which the Anker SOLIX Solarbank 3 E2700 Pro stores 2.7 kWh for the evening. The result: cover base load, store surpluses, reduce grid consumption – all without an electrician or special meter.

Why an 890 Wp Balcony Power Plant with Storage?

• Self-consumption > 95 %
PV yields charge the battery during the day, and in the evening it delivers up to 1200 W AC power.

• Plug & Play
The solar bank is simply installed between the module output and the socket. Plug in Schuko – done.

• Modularly expandable
Up to 5 expansion batteries can be connected – total capacity: up to 16.1 kWh. AC output expandable to 1200 W.

• Legally secure
The AC power can be limited to 800 W (legal limit in DE). A single registration is sufficient.

• Independent from the grid in emergencies
In island mode, the system autonomously supplies the refrigerator, router & lights during a power outage.

Configuration – Mounts & Cables

Mounting Options
• Balcony (round)
• Flat roof (also ballasted)
• Sloped roof
• Wall mounting
• Trapezoidal sheet (e.g., workshop, carport)

Connection Cables
• UV-resistant, double insulated, pre-assembled Schuko plug – Wieland optional

Installation in 3 Steps

1. Attach the mount – e.g., clamp, ballast, or fix on the roof

2. Connect solar modules – MC4 to solar bank, set up device

3. Connect solar bank with Schuko plug to the house grid – feeding & charging start automatically

Installation Time: approx. 60–90 minutes; a second person makes carrying easier.

Performance, Yield & Cost-effectiveness

• PV yield per year (south orientation, 30 °): approx. 900–1040 kWh
• Self-consumption without/with storage: approx. 85 % / > 95 %
• Electricity cost savings* (at 0.32 €/kWh): 290–330 €/year (+ advantage from storage shifting)
• CO₂ savings: around 520 kg per year

*Amortization depends on storage price and personal consumption profile.

Legal Framework (Germany)

• Approval-free up to 800 W AC feed-in – the solar bank can be throttled via app
• Registration in the market master data register required (~10 minutes effort)
• Notification to the grid operator (usually online form or PDF)
• Schuko operation is legal – Plug & Play allowed

FAQ (Selection)

Is bifacial worth it on the balcony?
Yes – bright surfaces like walls or floors reflect light to the module's rear side, which can yield up to 10 % more power.

What happens during a power outage?
The solar bank automatically switches to island mode (off-grid) and delivers up to 1200 W via the emergency Schuko.

Does my meter need to be replaced?
Only if your current meter runs backward. In this case, the grid operator will replace it with a bidirectional meter free of charge.

Is the system noisy?
No – the entire system operates without fans and is completely silent.

Do I need additional modules?
Not necessarily for an 890 Wp system. However, the solar bank is prepared for up to four PV strings and can be expanded at any time.
