FAQ Storage
How does a home battery perform now that net metering schemes in Europe are changing?
The focus is now on self-consumption. By charging a battery from Huawei, Sigenergy, or Sungrow during negative price hours or solar peaks, and discharging when rates are high, the customer lowers their energy bill immediately.
What is the role of AI in controlling a battery?
Systems from brands like Sigenergy use AI to predict weather forecasts and consumption patterns. The battery knows exactly when to charge at the lowest price, often reducing the payback period to 6 to 8 years.
How does the Depth of Discharge (DoD) affect battery life?
The DoD indicates what percentage of the capacity you can actually use. Modern LFP batteries at ESTG often have a 100% DoD. This means you can use the full capacity without damaging the lifespan.
Are the batteries at ESTG safe for residential installation?
Yes, we only supply LFP technology from brands like Growatt, Huawei, and Sigenergy. LFP is stable, cobalt-free, and has a very low risk of fire, which is important for safety and insurance.
Is a hybrid inverter always required to add a battery?
For new installations, a hybrid inverter is the most efficient choice (DC-coupled). For existing systems, brands like SolarEdge, Enphase, or SMA offer AC-coupled retrofit options to add storage without replacing the current inverter.
How does ESTG handle the new European 'Battery Passport' legislation?
From 2026/2027, batteries in the EU must have a digital passport. ESTG only works with transparent manufacturers committed to responsible raw material sourcing.
What does the European shift to Dynamic Pricing mean for the end user?
Across Europe, there is a move towards dynamic hourly prices. This makes combining solar panels with a smart Energy Management System (EMS) and battery storage attractive by storing energy when prices are low.
Why is 'Power-to-Heat' an important step for the European industry?
To phase out gas faster, Power-to-Heat solutions are a priority. Excess solar energy is converted into thermal energy via heat pumps or E-boilers. This acts as a thermal battery that is often cheaper than chemical storage.
