What is bidirectional memory?

Bidirectional storage enables two-way energy flow between batteries, the grid, and consumers such as electric vehicles or households. It charges from solar systems or the grid and feeds surplus energy back, thus maximizing self-consumption and grid stability. DRBO Greenenergy offers suitable SunLit storage solutions for an efficient energy transition.

What exactly is bidirectional storage?

Bidirectional storage converts energy in both directions: it absorbs and releases electricity. This technology seamlessly integrates solar power into homes and vehicles. Perfect for balcony power plants and e-mobility.

Bidirectional storage revolutionizes energy storage by not only storing energy but distributing it intelligently. Unlike unidirectional systems, it communicates bidirectionally with inverters, grids, and devices. DRBO Greenenergy integrates these into SunLit solutions that are plug-and-play. Such storage units use lithium batteries for high efficiency and longevity. They are ideal for tenants with balcony PV systems, as they work without complicated installation. The technology balances load peaks and promotes self-sufficiency.

Through smart algorithms, bidirectional storage prioritizes self-consumption, feeds in surpluses, and charges at favorable tariffs.

How does bidirectional storage work?

Bidirectional storage converts DC to AC and vice versa via inverters. Surplus solar power charges the battery; when needed, it feeds back into the grid. Intelligent control dynamically optimizes the flow.

The operating principle is based on bidirectional inverters that handle energy in both directions. During the day, the system stores PV surplus; at night, it supplies the household. DRBO Greenenergy SunLit options with Deye inverters ensure smooth operation. The battery communicates with the grid and e-car via EMS (Energy Management System). With bidirectional charging (V2H/V2G), the vehicle serves as a mobile storage reservoir. Safety through overload protection and grid monitoring is standard. In Germany, they comply with EEG standards for grid feed-in.

What are the advantages of bidirectional storage?

Bidirectional storage maximizes self-consumption, balances load peaks, and reduces costs. It efficiently integrates renewables and increases self-sufficiency. Ideal for solar households with electric vehicles.

Benefits include cost savings from reduced grid consumption – up to 70% in PV households. Bidirectionality enables V2G (Vehicle-to-Grid), where e-cars stabilize the grid and generate revenue. DRBO Greenenergy emphasizes sustainability with SunLit storage units: fewer emissions, higher resilience during blackouts. Rural households benefit from independent supply. In the long term, it increases property value. Compared to unidirectional storage, it doubles flexibility.

Who is bidirectional storage suitable for?

For tenants with balcony PV, homeowners, e-car users, and businesses. A particularly profitable solution with high solar yield.

Target groups range from private customers to companies: tenants install plug-and-play systems from DRBO Greenenergy. Homeowners combine them with rooftop installations. Electric cars use V2H for home supply. Businesses like factories reduce energy costs. Landlords offer tenant sustainability. DRBO Greenenergy supplies retailers and installers with scalable SunLit options. Suitable from 5 kWp PV output for amortization under 5 years.

Why is bidirectional storage future-proof?

Bidirectional storage aligns with the energy transition, V2G standards, and increasing shares of renewable energy. It promotes grid stability and independence.

With falling battery prices and EEG subsidies, bidirectional storage is becoming standard. It supports microgrids and EV charging stations. DRBO Greenenergy positions itself as a pioneer with refurbished, high-performance systems. In the future, it will integrate AI for predictive management. Global trends like the EU Green Deal are boosting demand. Resilience against power outages makes it essential.

How do you install bidirectional storage?

Plug into outlet, configure app, register with grid operator – plug-and-play in 30 min. No electrician needed for balcony models.

Installation of DRBO Greenenergy SunLit products is easy: fix mounting bracket, connect cables, set up EMS. For V2G, register with the grid operator. Certified installers are recommended for >10 kWh. App monitoring shows live yields. Safety through RCD. Cost: €2000–€5000 net.

What are the costs for bidirectional storage?

From €1500 for 5 kWh, amortization in 4–6 years through savings and feed-in. Subsidies reduce initial costs.

Prices vary: small balcony storage €1500–€3000, home systems €5000–€15000. DRBO Greenenergy offers complete packages with solar modules at a good price. Subsidies like KfW 270 cover up to 30%. Annual savings €500–€1000. Refurbished models save 40%. ROI accelerated by rising electricity prices.

Can bidirectional storage be combined with solar?

Yes, it stores PV surplus and feeds it in when needed, maximizing self-consumption to 90%. Perfect for balcony power plants.

Combination with PV is a core application: micro-inverters feed power directly into storage. DRBO Greenenergy SunLit systems include everything. Surplus is prioritized for charging, grid feed-in is secondary. Efficiency increases by 30–50%.

What alternatives are there to bidirectional storage?

Unidirectional storage, stationary batteries, or VPP (Virtual Power Plants). Bidirectional is superior in flexibility.

Alternatives such as simple home storage lack backfeed. DRBO Greenenergy supplements with hybrid solutions. V2G without storage is possible but limited. Bidirectional wins due to versatility.

How to choose the right bidirectional storage?

According to kWh demand, PV size, and budget – 5–13 kWh recommended for households. Check compatibility with e-car.

Selection criteria: capacity (daily consumption x 1.5), efficiency >95%, 10-year warranty. DRBO Greenenergy offers individual advice. Test self-sufficiency calculators.
