Battery Storage Systems for Solar Energy
Store the Sun. Power the Night.
At Sun Trust Energy LLP, we integrate the world’s most advanced storage technologies to ensure your property never goes dark. Whether it’s beating peak-hour tariffs or surviving a monsoon power cut, our battery solutions provide the ultimate security for your investment.
The 2026 Technology Standard:
Lithium Iron Phosphate (LFP) Dominance: In 2026, LFP has become the industry gold standard. Unlike older lithium technologies, LFP is non-flammable, cobalt-free, and offers an incredible lifespan of 6,000 to 10,000 cycles (up to 15–20 years of daily use).
Smart Energy Arbitrage: Our systems use AI to “buy low and use high.” They automatically store energy when solar is abundant or grid prices are low, and discharge it during peak evening hours when electricity rates are at their highest.
Modular “Stackable” Design: Energy needs grow, and your battery should too. We offer modular systems that allow you to start with 5kWh and scale up to 30kWh+ just by stacking additional units—no complex rewiring required.
Seamless Backup (Islanding): When the grid fails, our high-speed hybrid inverters switch to battery power in less than 20 milliseconds. Your lights, Wi-Fi, and fridge stay on without a flicker.
Why Add Storage to Your Solar System?
True 24/7 Independence: Use your solar energy even at 2 AM. Most solar-only homes only use 30% of what they generate; with a battery, that number jumps to 80-90%.
Protection from “Export Limits”: Many utility companies are now restricting how much solar power you can send back to the grid. A battery ensures you keep that extra power for yourself instead of wasting it.
Silent & Clean Backup: Replace noisy, polluting diesel generators with a silent, maintenance-free battery box that fits elegantly on your wall or in your garage.
EV Charging Synergy: Use your stored solar energy to charge your Electric Vehicle at night, making your commute 100% free and carbon-neutral.
Choosing the Right Capacity:
Household Type | Recommended Storage | Typical Backup |
Small Home | 5 kWh – 10 kWh | Lights, Fans, TV, Wi-Fi (Overnight) |
Medium Villa | 10 kWh – 20 kWh | Above + Fridge & 1 AC (limited hours) |
Large Estate/C&I | 30 kWh – 100 kWh+ | Full autonomy including multiple ACs & Pumps |
