FAQs
Q: What is the maximum charging and discharging power?
A: The maximum charging power is 2600W. 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 E series is plug-and-play AC-coupled system and does not include photovoltaic (PV) input ports. Therefore, it does not support direct connection to solar panels.
Q: Does this home energy storage system provide emergency or backup power?
A: Yes. The system provides 2600 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: The Nex E series does not connect directly to solar panels. Instead, it is designed for homes with an existing grid-connected PV system, where solar energy is converted into AC electricity through an inverter.
Q: What is the maximum charging power of the PV ports?
A: The Nex E series does not connect to PV directly.
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 €562.3 is based on the following product configuration: a 4 kW residential photovoltaic (PV) system combined with a 6.0288 kWh battery energy storage system. The calculation assumes typical mid-latitude European solar generation conditions.
A 4 kW PV system generates approximately 16 kWh of electricity per day, resulting in an estimated annual PV generation of 5,840 kWh.
With a battery usable capacity of 5.426 kWh (assuming 90% depth of discharge), the battery can supply approximately 1980.49 kWh of usable energy annually.
The base PV self-consumption rate without storage is assumed to be 35%, while the addition of an energy storage system increases the self-consumption rate to 75%, representing an improvement of 40 percentage points.
Electricity prices used in the calculation are based on typical European market assumptions:
- PV self-consumption electricity value: €0.40/kWh
- Time-of-use (TOU) electricity prices:Peak price: €0.45/kWhOff-peak price: €0.30/kWh
The battery system is assumed to operate with a round-trip efficiency of 88%.
Under these conditions, the system can achieve combined economic benefits through increased PV self-consumption and time-of-use electricity arbitrage, resulting in estimated annual savings of approximately €562.3 and a reduction of about 544 kg of CO₂ emissions per year.
Savings Calculation
Annual savings from increased PV self-consumption:16 kWh/day × 40% × €0.40/kWh × 365
≈ €934.4/year
Battery discharge energy per day (considering efficiency):5.426 kWh × 0.88 = 4.775 kWh/dayDaily arbitrage benefit:(4.775 × €0.45) − (5.426 × €0.30)
= €1.780/dayAnnual arbitrage savings:€1.780 × 365
≈ €190.1/year
Hybrid Mode (Estimated Practical Savings)Estimated real-world savings combining both operating strategies:(€934.4 + €190.1) ÷ 2
≈ €562.3/year
Environmental ImpactGrid electricity CO₂ emission factor:
0.233 kg CO₂/kWhAdditional PV self-consumed energy:16 × 40% × 365 = 2,336 kWh/yearEstimated annual CO₂ reduction:2,336 × 0.233
≈ 544 kg CO₂/year

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.
