## Overview

We provide **professional solar inverter diagnostics and replacement services** for residential systems across Belgium.

Our approach is not limited to simple replacement — we focus on: - Identifying **hidden energy losses**- Detecting **night-time consumption issues**- Analyzing **grid-related instability**- Ensuring **optimal system performance**

Every project is handled with a **technical, data-driven approach**, ensuring long-term reliability and financial efficiency.---

--- ## Diagnostic & Problem Identification

Before any replacement, we perform a **complete system analysis**.

We check: - Night-time inverter consumption - Grid voltage behavior - Production vs expected output - Error logs and instability patterns

This allows us to identify issues such as: - Hidden standby consumption - Grid overvoltage problems - Aging electronic components

👉 Most of these issues are **not visible to the average user**

--- ## Inverter Replacement Service

We replace all major residential inverter types with modern, high-efficiency solutions.

### Supported systems: - SMA (Sunny Boy series) - Huawei (SUN2000) - Sungrow - SolarEdge - Growatt / Solis ### Service includes: - Safe removal of old inverter - Installation of new unit - DC & AC reconnection - Full system testing - Configuration according to Belgian grid standards --- ## Grid Compatibility & Optimization

Modern solar environments require proper configuration.

We ensure: - Correct **country/grid settings (Belgium)**- Voltage tolerance optimization - Stable injection into the grid - Reduced disconnection issues

👉 This is critical in areas with high solar density.

--- ## Night Consumption Optimization

One of the key improvements after replacement: - Old inverter: 50–100W night consumption ❌ - New inverter: <5W standby ✅

👉 This directly improves your system’s **financial return**

--- ## System Performance Upgrade

By replacing the inverter, you achieve: - Higher efficiency (up to 98%+) - Stable operation - Accurate monitoring - Reduced energy losses

Even with older panels, a new inverter can significantly improve overall performance.--- ## Real-World Expertise

Our services are based on **real diagnostic cases**, not just theoretical assumptions.

We have identified issues such as: - Hidden night consumption - Misleading production data - Undetected system inefficiencies

👉 These problems are often **not clearly communicated by manufacturers**

--- ## Installation Quality & Safety

All installations are performed with: - Compliance with Belgian electrical standards (RGIE) - Proper grounding and protection - Clean cable management - Safe mounting conditions

We also consider environmental factors such as: - Ventilation - Distance from gas lines - Long-term durability --- ## Service Gallery

--- ## Transparent Pricing Reference

- **Basic inverter replacement** — €150 – €300 - **Standard residential system (3–5 kW)** — €400 – €900 - **Advanced configuration & diagnostics** — €500 – €1200 - **Custom projects** — Price on request

- Prices exclude VAT - Hardware not always included - Final pricing depends on system condition
