Humsienk HAVEN 51.2V 314Ah 16kWh LiFePO4 Battery

A wall-mounted battery is a space-saving energy storage system designed to be installed on a wall, ideal for home backup power and residential solar setups.

We use top-tier Grade A LiFePO4 cells. According to our lab data, it can achieve 15,000+ cycles when operated at 60% Depth of Discharge (DOD).

We use only premium Grade A LiFePO4 cells. Under optimal conditions (60% Depth of Discharge), this battery is engineered to deliver an industry-leading 15,000+ cycles. Even with heavy daily use, it is designed to provide reliable power for well over a decade.

A: With a massive 16.076kWh of usable energy, this battery is an absolute powerhouse for home backup or large solar systems. A single fully charged unit can run essential appliances like a refrigerator for over a week, keep a heavy-duty air conditioner running for 15+ hours, or power your entire home’s lights, TV, and Wi-Fi for days during a blackout.

Yes! It features both a built-in LCD touchscreen display and Bluetooth connectivity. You can easily monitor real-time data—such as State of Charge (SOC), voltage, temperature, and cycle counts—directly from the built-in screen or remotely via our dedicated mobile APP.

This battery features a dual-protection system. It integrates an advanced 200A Smart Battery Management System (BMS) alongside a physical built-in circuit breaker. This provides ultimate protection against overcharging, deep discharging, short circuits, and extreme high/low temperatures.

Absolutely. Designed for scalable energy solutions, you can connect up to 15 of these units in parallel. This allows you to expand your total energy storage capacity to an incredible 241.15kWh, perfect for large-scale residential, commercial, or off-grid setups.

While it is a wall-mounted design intended to save floor space, it is incredibly user-friendly to position. The battery comes equipped with swivel wheels and a foot brake, allowing you to easily roll it into place before securing it. Note: Due to its large capacity and weight, we strongly recommend having two people or a certified electrician handle the final wall-mounting process.

Our 200A Smart BMS supports standard CAN, RS485, and RS232 communication protocols, ensuring seamless plug-and-play integration. It is widely compatible with most mainstream hybrid and off-grid inverter brands on the market, including Victron, Deye, Growatt, SMA, Solis, and Megarevo.

The robust outer casing features an IP54 rating, making it highly durable and resistant to dust and water splashes. However, to maximize its 15,000-cycle lifespan, we recommend installing it in a sheltered area, such as a garage, basement, or utility room, away from direct sunlight and heavy rain.

• Avoid Extreme Temperatures: High heat accelerates degradation, and charging at temperatures below 0°C (32°F) can cause permanent damage unless the battery has a built-in self-heating function .
• Use a Compatible Charger: Always use a charger or inverter with charging profiles specifically designed for LiFePO4 batteries.
• Optimal Storage: If storing the battery for a long period, charge it to 40%-60% state of charge and keep it in a cool, dry place. Check and recharge it every 3-6 months.
• Regular Use: Periodic full charge/discharge cycles can help the BMS calibrate the state of charge reading for better accuracy.

Most wall-mounted batteriessupport parallel connectionto increase total capacity (e.g., from 5kWh to 15kWh). When paralleling, always use batteries of the same brand, model, and age. Use cables of the same length and gauge for each battery to ensure balanced charging/discharging. Adhere to the manufacturer's limit on the maximum number of parallel units.
