1. With the SAMDUO Intelligence, households can save up to €1,897 per year on electricity. This solution significantly reduces household energy costs while supporting clean, efficient energy use. For compliance with German regulations, the installed PV system must not exceed 7 kW, and inverter output must not exceed 800 W. Systems above these thresholds require registration and installation by a certified electrician, in accordance with local grid connection rules. All PV components, including panels, inverters, and storage devices, must be registered in MaStR (Marktstammdatenregister, www.marktstammdatenregister.de) and comply with local grid operator regulations. Based on southern Germany solar data, 1 kW of solar panels generates approximately 1,100 kWh per year. Fixed electricity price is €0.40 per kWh, peak-valley difference is €0.132 per kWh, and the AI daily cycle purchases 40% of external electricity during low-tariff hours to use during peak hours. The German grid carbon emission factor (2026) is 0.425 kg CO₂ per kWh, and one tree absorbs about 18–20 kg CO₂ per year.Calculations: Household annual usage: 2,000 kWh; Installed solar: 1 kW; Battery: Nex P2800 Pro (2.736 kWh); Theoretical battery storage per year = 2.736 × 0.99 × 365 = 988.65 kWh; Solar self-consumption revenue = 988.65 × 0.40 = €395.46; External grid electricity = 2,000 − 1,100 = 900 kWh; AI peak-valley arbitrage revenue = 900 × 40% × 0.132 = €47.52; Annual total savings = 395.46 + 47.52 = €443; CO₂ reduction = 988.65 × 0.425 ≈ 420 kg CO₂; Planting tree equivalent = 420 ÷ 18 ≈ 23 trees/year Household annual usage: 3,000 kWh; Installed solar: 2 kW; Battery: Nex P2800 Pro + BP2800 (Total 5.472 kWh); Theoretical battery storage per year = 5.472 × 0.99 × 365 = 1,977.31 kWh; Solar self-consumption revenue = 1,977.31 × 0.40 = €790.92; External grid electricity = 3,000 − 2,200 = 800 kWh; AI peak-valley arbitrage revenue = 800 × 40% × 0.132 = €42.24; Annual total savings = 790.92 + 42.24 = €833; CO₂ reduction = 1,977.31 × 0.425 ≈ 840 kg CO₂; Planting tree equivalent = 840 ÷ 18 ≈ 47 trees/year Household annual usage: 4,000 kWh; Installed solar: 4 kW; Battery: Nex P2800 Pro + 2 × BP2800 (Total 8.208 kWh); Theoretical battery storage per year = 8.208 × 0.99 × 365 = 2,965.96 kWh; Solar self-consumption revenue = 2,965.96 × 0.40 = €1,186.38; External grid electricity = 4,000 − 4,400 = − (all consumption covered by solar/battery); AI peak-valley arbitrage revenue = 1034 × 40% × 0.132 = €54.60; Annual total savings = 1,186.38 + 54.60 = €1,241; CO₂ reduction = 2,965.96 × 0.425 ≈ 1,261 kg CO₂; Planting tree equivalent = 1,261 ÷ 18 ≈ 70 trees/year Household annual usage: 5,000 kWh; Installed solar: 4 kW; Battery: Nex P2800 Pro + 3 × BP2800 (Total 10.944 kWh); Theoretical battery storage per year = 10.944 × 0.99 × 365 = 3,954.61 kWh; Solar self-consumption revenue = 3,954.61 × 0.40 = €1,581.84; External grid electricity = 5,000 − 4,400 = 600 kWh; AI peak-valley arbitrage revenue = 1,045 × 40% × 0.132 = €55.18; Annual total savings = 1,581.84 + 55.18 = €1,637; CO₂ reduction = 3,954.61 × 0.425 ≈ 1,681 kg CO₂; Planting tree equivalent = 1,681 ÷ 18 ≈ 93 trees/year Household annual usage: 6,000 kWh; Installed solar: 4 kW; Battery: Nex P2800 Pro + 4 × BP2800 (Total 13.68 kWh); Theoretical battery storage per year = 13.68 × 0.99 × 365 = 4,943.27 kWh; Solar self-consumption revenue = 4,400 × 0.40 = €1,760; External grid electricity = 6,000 − 4,400 = 1,600 kWh; AI peak-valley arbitrage revenue = 1,600 × 40% × 0.132 = €84.48; Annual total savings = 1,760 + 84.48 = €1,844; CO₂ reduction = 4,400 × 0.425 = 1,870 kg CO₂; Planting tree equivalent = 1,870 ÷ 18 ≈ 104 trees/year Household annual usage: 7,000 kWh; Installed solar: 4 kW; Battery: Nex P2800 Pro + 5 × BP2800 (Total 16.416 kWh); Theoretical battery storage per year = 16.416 × 0.99 × 365 = 5,931.92 kWh; Solar self-consumption revenue = 4,400 × 0.40 = €1,760; External grid electricity = 7,000 − 4,400 = 2,600 kWh; AI peak-valley arbitrage revenue = 2,600 × 40% × 0.132 = €137.28; Annual total savings = 1,760 + 137.28 = €1,897; CO₂ reduction = 4,400 × 0.425 = 1,870 kg CO₂; Tree equivalent = 1,870 ÷ 18 ≈ 104 trees/year
2. All promotional data, performance metrics, and financial savings projections for this product are based on typical operating conditions, standardized testing environments, and idealized assumptions. Actual performance, cost savings, and operational stability may vary based on a variety of factors, including but not limited to geographical location, energy consumption behavior, grid conditions, utility tariff policies, and equipment configurations. This product is intended solely as a home energy optimization device and is not a substitute for professional electrical safety protection devices. Installation and usage must comply with all local grid regulations and electrical codes. Complete compatibility with third-party devices and 100% zero-export performance are not guaranteed; actual real-world operation shall prevail.
3. All data is based on idealized operational assumptions utilizing a system configuration of one (1) main unit paired with five (5) stacked battery packs. Actual results may vary depending on geographical location, inaccuracies in solar generation forecasting, solar panel orientation, utility rates, and other external factors.
4. SAMDUO Intelligence
AI features (including AI predictive scheduling, Edge AI, etc.) are calculated based on algorithmic models and typical electricity usage, utility tariff, and photovoltaic (PV) data. Actual performance may vary due to factors such as geographical location, energy consumption behavior, real-time utility pricing, and network conditions. Certain AI features are currently planned for future release; availability is subject to official product updates. Actual features within the samduo app may vary, and all screenshots provided are for illustrative purposes only.
5. Zero-Export (Zero Grid-Feed-In)
The zero-export feature requires a compatible, locally compliant smart meter and is calculated based on typical household operating conditions. Actual performance is subject to grid environments, load demands, and PV power output; 100% complete zero-feed-in cannot be guaranteed. Actual operation must comply with local grid regulatory requirements.
6. PowerMesh™ TechnologyPowerMesh™ multi-unit zero-feed-in and energy scheduling features are based on the assumption of a standardized grid environment under a single meter. Actual multi-unit synchronization and performance are influenced by meter protocols, grid environments, the number of connected devices, and installation layouts. The maximum multi-unit expansion capacity is a theoretical limit; actual performance depends on on-site conditions. Installation and usage must comply with local grid regulations and electrical safety codes.
7. 2400W Bi-directional On/Off-Grid Power
Achieving the full 2400W input and output capacity requires the main unit to be paired with at least one expansion battery pack. The base input and output capacity of the standalone main unit is 1200W.
