Case Study: Smarter Living with Deege Solar & Fogstar

Case Study: Smarter Living with Deege Solar & Fogstar

When one Dartford homeowner decided to take control of rising energy costs, they didn’t just stop at solar panels. With a smart install from Deege Solar and over 30kWh of Fogstar storage, the house is now geared up for EV charging, a future heat pump, and near-total grid independence.

Partnering with Deege Solar for installation and Fogstar for scalable storage, the project transformed a standard residential property into a self-sufficient, fully electric powerhouse,  ready for EV charging, a heat pump, and whatever the future demands.

🌞 The Goal: Cut Bills, Boost Control

With electricity priced at 24.4p per unit and annual usage topping 7,000 kWh, the homeowner’s priorities were clear:

  • Slash reliance on the grid
  • Build a system that could grow with future tech (like an Air Source Heat Pump)
  • Maximise self-consumption of solar power

A south-facing roof set the stage for maximum solar output. The final design? A 9.66kWp solar PV system paired with over 30kWh of Fogstar battery storage - built for scalability, reliability, and long-term efficiency.

🔋 Why Fogstar? Performance Without the Premium Price Tag

This was never going to be a “box-standard” domestic install. After more than a year of research, the homeowner made a deliberate choice to go with Fogstar batteries.

“I wanted function over form. Fogstar’s batteries gave me the flexibility, rugged build quality and value I couldn’t find elsewhere. Add in UK-based support and great reviews - it was an easy decision.”

At the heart of the setup are two Fogstar 16kWh Seplos V4 DIY bundles, powered by MB31 Grade A EVE cells. Combined with Smart BMS integration and seamless compatibility with Sunsynk inverters, the result is a system that’s simple to monitor, easy to expand, and built to last.

Scalability was non-negotiable - this system can grow to 16 battery units (257kWh total storage) if the homeowner wants. That’s serious futureproofing.

⚡ Installation

Thanks to Deege Solar’s expertise and detailed pre-planning, the install went smoothly. As the homeowner put it: “As simple as putting together LEGO.” By choosing Fogstar’s batteries, the customer kept installation costs down, retained full control, and built a system that rewards hands-on knowledge.

🛠️ The System at a Glance

  • Solar: 21 x 460W Neostar 2S Aiko All-Black Panels
  • Storage: 2 x Fogstar 16kWh Seplos V4 DIY Bundles (MB31 Grade A EVE Cells)
  • Inverter: 8.8kW ECCO Sunsynk Hybrid
  • EV Charger: Myenergi Zappi
  • Monitoring: Solar Assistant (Raspberry Pi)
  • Extras: Active balancers, bird protection, manual changeover switch.

📊 Results So Far

The system is already exceeding expectations.

“Fogstar’s batteries have been faultless. I upgraded the balancers myself, and I’ve been impressed with how closely Fogstar works with Seplos to keep improving their products. Not many brands listen to their community like that.”

The next step? Switching out the gas system for a heat pump - turning the property into a 100% electric home. Confidence in the system is high.
