GOOTU Unveils IP65 Hybrid Solar Inverter + 15kWh Battery System: Three Flexible Modes for All-Scenario Off-Grid/Grid-Tied Power
In response to growing demand for intelligent, sustainable, and high-performance energy systems, a new IP65 hybrid inverter paired with a 15kWh energy storage battery is setting a new benchmark in efficient solar power management. Designed to operate seamlessly across multiple modes — SUB, SBU, and MKS — this system empowers users to optimize energy usage according to different power environments and grid conditions.
The foundation of this system is GOOTU’s IP65 waterproof/dustproof hybrid solar inverter, engineered to withstand extreme outdoor conditions (a critical advantage for regions like the Middle East’s deserts or India’s monsoon-prone areas). Paired with a 15kWh LiFePO4 battery (3000+ cycle life, high safety), the system balances portability, capacity, and durability—making it ideal for residential, commercial, or small industrial use.
Mode 1: SUB (Solar → Utility → Battery) – Grid-Tied with Cost Savings
For users in areas with stable but costly grid power (e.g., urban India or Pakistan), the SUB mode prioritizes solar energy first:
Solar power directly supplies connected loads.
Excess solar energy feeds back to the grid (where net metering is allowed), reducing electricity bills.
Only when solar and grid power are insufficient does the 15kWh battery activate as a backup.
This mode is perfect for urban households or small shops looking to cut energy costs while maintaining grid reliability. “In cities like Delhi, where grid tariffs are rising, SUB mode lets users maximize solar savings without over-relying on batteries,” says GOOTU’s Product Director.
Mode 2: SBU (Solar → Battery → Utility) – Off-Grid Priority with Grid Backup
For users in remote areas with unstable grids (e.g., rural Middle East or Pakistani villages), SBU mode ensures uninterrupted power:
Solar energy charges the 15kWh battery first.
The battery powers loads when solar is unavailable (e.g., night, cloudy days).
The grid only kicks in if the battery is fully discharged (a rare scenario with 15kWh capacity).
This mode eliminates dependence on erratic grid supply—critical for facilities like remote clinics or agricultural pumps. A pilot user in rural Oman noted: “With SBU mode, our farm pumps run 24/7 using solar and battery; we only use grid power during weeks of heavy sandstorms.”
Mode 3: MKS (Manual Keep Supply) – Customized Power Control
For commercial users (e.g., small factories, construction sites) with variable load demands, MKS mode offers manual customization:
Users set priority (solar/battery/grid) based on real-time needs (e.g., prioritize battery during peak grid tariffs, solar during daytime).
The system maintains a minimum battery SOC (State of Charge) to ensure emergency backup.
This flexibility is a game-changer for businesses with fluctuating energy costs. “A construction site in Dubai uses MKS mode to power tools with solar during the day, switch to battery at sunset, and avoid grid use entirely during peak hours—cutting daily energy costs by 40%,” explains a GOOTU sales manager.
Why This System Stands Out for Global Markets?
Beyond its three modes, the IP65 inverter + 15kWh battery system offers:
Harsh-Environment Durability: IP65 rating resists dust, rain, and temperatures up to 50°C.
Long Lifespan: 15kWh LiFePO4 battery lasts 3000+ cycles (≈10 years of use).
Easy Monitoring: Plug-and-play WiFi dongle lets users track mode status, battery SOC, and solar harvest via mobile app.
“With this system, we’re not just selling a product—we’re delivering a solution that adapts to how people actually use power in different regions,” says GOOTU’s CEO. “Whether it’s a city apartment in India or a remote farm in the Middle East, these three modes ensure users get the most out of their solar investment.”
