Stay Safe, Secure and Fully Powered — No Matter What
Enjoy peace of mind with intelligent battery storage systems that protect your home or business from blackouts, high tariffs and uncertainty — all while using clean, renewable energy.
🔋 On-Grid Battery Storage Systems for Solar Energy Homes
What is an On-Grid Battery Storage System?
On-grid battery storage systems are connected to the public electricity grid and work in tandem with solar panels. These systems allow homeowners to use solar energy during the day and store excess power for later use or export to the grid — reducing dependency on expensive electricity.
💡 Example: MARSTEK JUPITER C/E – Plug & Play Solar Battery Storage
- ✅ Integrated micro inverter (800 W AC) – plug & play, no professional installation.
- ✅ 4 MPPTs – up to 2000 W solar input for efficient energy tracking.
- ✅ Battery capacity options: 2,560 Wh (Jupiter C) or 5,120 Wh (Jupiter E).
- ✅ Anti-feed-in function – 100% energy used for self-consumption.
- ✅ IP65-rated – works in -20 °C to +55 °C.
✅ Benefits of On-Grid Storage
- 💰 Lower energy bills – use stored solar power during peak hours.
- ⚡ Quick setup – install in just 5 minutes, perfect for compact spaces.
- 🔋 Safe & long-lasting – reliable LiFePO₄ batteries.
🏕️ Off-Grid Battery Storage Systems
What is an Off-Grid System?
Off-grid battery systems are entirely independent from the utility grid. Powered by solar panels and optionally a generator, they supply energy to remote homes, mobile setups, or locations without infrastructure.
🏠 Common Use Cases
- Remote cottages and holiday homes
- Off-grid lodges, cabins, or camps
- Mobile medical or telecom stations
✅ Benefits of Off-Grid Storage
- 🔌 Total independence – no reliance on the grid.
- 📈 Scalable – add panels or generator as needed.
- 💸 Cost-saving – no grid fees or infrastructure.
- 🌿 Eco-conscious – reduce fossil fuel usage.
⚡ Hybrid Battery Storage Systems
What is a Hybrid System?
Hybrid battery systems combine grid connection and off-grid capability. They provide backup during blackouts while optimising energy between solar, grid, and battery for maximum efficiency.
🌞 Example: MARSTEK VENUS D
- ✅ 4 kW solar input with 4 MPPTs
- ✅ 2.2 kW AC coupling – seamless grid interaction
- ✅ Automotive-grade LiFePO₄ batteries – over 6,000 cycles, 10-year performance guarantee
- ✅ IP65 – weather- and dust-proof
- ✅ Smart metering – optimises charging by tariff rate
✅ Benefits of Hybrid Systems
- 🔋 Reliable backup – uninterrupted energy during outages
- 💰 Cost-effective – store night or solar power, use during peak tariffs
- ⚙️ Expandable – scale up for larger setups
- 🧠 Smart – manages power flows automatically
