Learn about home battery storage

Net Metering

What changes after 2026 for solar homeowners?

The Dutch net metering scheme is ending. That means surplus solar power will be worth far less than it is today. This article explains why storing your own energy becomes more attractive.

Technology

How does a home battery actually work?

From charging during the day to discharging in the evening, this guide explains energy storage in plain English, including the role of the inverter and the specs that really matter.

Safety

LiFePO4 or lithium-ion: which is safer?

Not every battery chemistry is the same. LiFePO4 is more stable, lasts longer, and is better suited to home use. We compare the differences clearly and simply.

Solar Output

How much do your solar panels really produce?

The number of panels only tells part of the story. Orientation, roof angle, and shading make a big difference, and our ROI calculator takes those into account.

Energy Bills

How to better understand your energy bill

Feed-in charges, supply rates, and net metering are often mixed together. This overview helps you understand which numbers really affect your payback period.

Installation

Set up your StekkerBox without the hassle

From unboxing to connecting the app, this guide shows how a plug-and-play home battery can be ready to use quickly without major electrical work.
