FAQs
Q: What is the maximum charging and discharging power?
A: The maximum charging power is 1200W. The maximum on-grid discharging power is 800W, in complance with plug-and-play regulatory limits.
Q: What is the maximum PV input power?
A: The Nex P2800 series supports max 3600W PV input power.
Q: Does this home energy storage system provide emergency or backup power?
A: Yes. The system provides 1200 VA of off-grid backup power, allowing it to run essential appliances during a power outage.
Q: Can we use it to trade in the electricity imbalance market?
A: Yes. The system can be used for related energy trading and grid dispatch applications.
Q: Does the system connect to other photovoltaic (PV) systems?
A: If solar panels are installed without an inverter, the Nex P series may be a great choice. Compatibility, however, depends on the panel specifications, which must meet the required input parameters: 12–60 V input voltage and up to 32 A per channel (four channels total).
Q: What is the maximum charging power of the PV ports?
A: The Nex P series has 4 PV input channels, each supporting a maximum of 900 W, with a total maximum charging power of 3600 W.
Q: Can the system automatically optimize operation based on electricity prices and user habits?
A: Yes. This capability will be supported through future updates.
Q: How is data privacy handled?
A: The system is designed to protect user data and privacy in compliance with the GDPR (General Data Protection Regulation).
Q: Does the smart meter require professional installation?
A: It is recommended that the smart meter be installed by an experienced technician or an authorized installer to ensure proper setup and safe operation.
Comments
The calculation of the annual savings of approximately €1,574 is based on the following system configuration: a photovoltaic (PV) system supporting up to 3,600 W of solar panels combined with an energy storage system with a daily storage capacity of 16.41 kWh.
According to data from the European Commission’s PVGIS platform (https://re.jrc.ec.europa.eu/pvg_tools/en/tools.html), in southern Germany a 1,000 W solar panel can generate up to 1,100 kWh of electricity per year. Based on this reference value, a system supporting 3,600 W of solar panels can generate approximately 3,960 kWh of electricity annually.The annual energy storage throughput is estimated at 5,989.7 kWh, calculated from a daily storage capacity of 16.41 kWh.The system assumes a self-consumption rate of 85%, based on the independence calculator developed by HTW Berlin (https://solar.htw-berlin.de/rechner/unabhaengigkeitsrechner).Electricity pricing assumptions used in the calculation include:
- Fixed electricity price: €0.40/kWh
- Peak-to-valley price difference: €0.132/kWh
Under these assumptions, the system generates economic benefits through direct PV self-consumption and AI-optimized charging strategies, resulting in estimated annual electricity cost savings of approximately €1,574.
Savings Calculation
Annual Electricity Cost SavingsTotal savings consist of self-consumption savings and AI-optimized charging savings.Self-consumption savings:3,960 kWh × 85% × €0.40 = €1,346.4AI-optimized charging savings:(5,989.7 − 3,960 × 85%) × €0.132 ≈ €227.6Total annual savings:€1,346.4 + €227.6 ≈ €1,574/year
Environmental Impact
Estimated CO₂ reduction factor for solar electricity:0.997 kg CO₂ per kWhAnnual self-consumed solar energy:3,960 kWh × 85% = 3,366 kWhEstimated annual CO₂ reduction:3,366 × 0.997 ≈ 3,356 kg CO₂/year
Disclaimer
All calculations are based on typical operational assumptions and average European solar generation conditions. Actual results may vary depending on geographical location, solar panel orientation, local electricity tariffs, weather conditions, and system operation patterns.
