APsystems' EZ1 inverter revolutionizes balcony power plants with its high efficiency and smart connectivity. It maximizes energy yields with minimal effort and sustainably reduces electricity costs. With up to 97.3% efficiency and easy app monitoring, it offers tenants and homeowners a reliable solution for the decentralized energy transition.

What is the current state of the solar industry?

In Germany, over 400,000 balcony power plants are installed annually, representing a growth of 537% since 2023. Nevertheless, they only cover 1-2% of private electricity demand, as many systems suffer performance losses due to shading and weather conditions. According to the German Federal Network Agency's 2025 report, the average yield per system is only 350 kWh net.

This gap is created by unoptimized inverters, which lose up to 30% of their power output in partial shading. Households continue to pay high electricity prices of 38 cents/kWh, while solar potential remains untapped. DRBO Greenenergy addresses this with practical solutions for tenants and homeowners.

Dependence on grid electricity is growing: 70% of Germans plan solar investments, but installation barriers slow down 40%. Pain points like complexity and low efficiency frustrate users daily.

What are the weaknesses of traditional solutions?

Traditional string inverters connect modules in series, so a shaded panel can shut down the entire chain – losses of up to 50% are possible. They often require electricians and grid connection permits, which drives costs up to €500-800.

Central inverters lack smart features: No real-time monitoring, limited MPPT channels, and IP54 protection are insufficient for balcony conditions. According to the Photovoltaik-Institut München, their lifespan decreases by 20% in humid conditions.

Compared to microinverters like the EZ1, they offer no flexibility: Expandability is lacking, and app integration is rudimentary. DRBO Greenenergy eliminates these disadvantages with the EZ1.

What core functions does the EZ1 inverter offer?

The EZ1 from APsystems delivers 800 W nominal output with two independent MPPT channels for 20 A per input, optimal for east-west orientation. It achieves 97.3% efficiency and MPPT efficiency of 99.5%, with IP67 protection for -40 to +65 °C.

Integrated Wi-Fi/Bluetooth enables app monitoring via AP EasyPower: Real-time data, CO2 savings, and remote power control (600-800 W). Compatible with storage systems like SunLit BK215, including NA protection relay.

DRBO Greenenergy integrates the EZ1 into plug-and-play packages with solar modules and accessories. Weight: 3 kg, dimensions: 263 x 218 x 37 mm – ideal for balconies.

Why does the EZ1 outperform traditional inverters?

Criterion	Traditional String Inverters	EZ1 Inverter (DRBO Greenenergy)
MPPT Channels	1 (Series losses up to 50%)	2 independent (Losses < 5%)
Efficiency	94-96%	97.3% (max. yield +15%)
Protection class	IP54 (limited weather resistance)	IP67 (extremely robust)
Monitoring	No App/Cloud	Wi-Fi/Bluetooth + App
Installation	Electrician needed (€500+)	Plug-and-play (10 min.)
Expandability	Fixed	Up to 4 kWp + storage
Price per Watt	€0.25/W	€0.12/W (higher ROI)

The EZ1 achieves 20-30% more yield through modular optimization. DRBO Greenenergy offers complete solutions for quick amortization in 2-3 years.

How to install the EZ1 inverter?

Connect modules: Two PV modules via MC4 connectors to MPPT inputs (16-60 V).
Connect Betteri plug: Secure output with Schuko cable.
Mounting: Attach bracket to balcony, hook in EZ1 (IP67).
Set up app: Pair Wi-Fi/Bluetooth, calibrate power to 800 W.
Commissioning: Switch on, check grid protection, start monitoring.

Total duration: 15 minutes, no electrician required. DRBO Greenenergy provides instructions and accessories.

When is the EZ1 suitable for typical scenarios?

Scenario 1: Tenant with East-West Balcony
Problem: Shading halves yield (200 kWh/year). Traditionally: String inverter unusable. After EZ1: 450 kWh/year, app shows +125% boost. Key Benefit: €170 electricity savings.

Scenario 2: Family with Storage Needs
Problem: Daytime surplus wasted, grid electricity expensive at night. Traditionally: No storage integration. After EZ1 + BK215: 80% self-consumption, 600 kWh stored. Key Benefit: Annual savings €250.

Scenario 3: Landlord with Multi-Family House
Problem: Tenants hesitate due to complexity. Traditionally: High installation costs. After EZ1 packages: 10 systems in 2 hours, yield 3,500 kWh. Key Benefit: Rent increase €50/apartment.

Scenario 4: Small Business with Terrace
Problem: Fluctuating consumers, 40% losses. Traditionally: Central inverter overwhelmed. After EZ1: Real-time optimization, 720 kWh/module. Key Benefit: ROI in 18 months.

DRBO Greenenergy supports everyone with B2B and B2C packages.

Why is the EZ1 indispensable now?

By 2030, balcony power plants are to contribute 12 GW, but only smart microinverters like the EZ1 scale efficiently. New EEG rules allow 800 W from 2025, increasing yields by 33%. DRBO Greenenergy is driving this forward, with Trustpilot 4.6/5 and local consulting. Invest today for energy freedom tomorrow.
