Applications

Home Backup Power

Keep critical circuits running during outages—lights, Wi-Fi router, refrigerator (typical duty-cycle), TV, fans, and home office devices. With split-phase output (L1-N: 3.6kW / L2-N: 3.6kW / L1-L2: 7.2kW) and pure sine wave inverter, your sensitive electronics stay stable and protected.

7200W Ultra-Thin Wall-Mounted Solar Battery for Log Cabins

Off‑Grid & Remote Power

Pair with PV panels for clean, self-sufficient off‑grid power. The system features dual MPPT inputs (200–480V, 9kW total) and wide PV voltage range (200–550V, up to 12kW), supporting flexible solar array configurations to match remote cabins, tiny homes, or off‑grid workshops.

7200W Solar PV and Storage System

Hybrid Self‑Consumption

Charge from solar during the day, use stored 7.68kWh LiFePO₄ energy at night, and automatically top up from the grid when needed. This maximizes solar utilization, reduces peak‑hour grid reliance, and provides seamless backup when the grid fails.

Frequently Asked Questions (FAQ)

It integrates a 7.68kWh BYD LiFePO₄ battery, a 7.2kW split-phase off-grid inverter, and dual MPPT solar controllers into an ultra-thin wall-mounted design (120mm depth). Unique features include baseboard LED lighting (customizable color, pattern, and brightness), support for L1/L2 split-phase output (120/240V), and off-grid backup. It is ideal for homes, apartments, or garages where space is limited but reliable backup power is needed.

Split-phase means the system provides three output combinations: L1–N (3.6kW), L2–N (3.6kW), and L1–L2 (7.2kW). This allows direct powering of standard North American or Japanese 120V/240V appliances (e.g., high-power air conditioners, water pumps, electric ovens) without an external transformer, making it perfect for off-grid homes.

The system uses genuine BYD LiFePO₄ cells. At 80% depth of discharge (DoD) and 25°C ambient temperature, it delivers ≥4,000 cycles. With one full charge/discharge per day, this equals more than 10 years of service life. The battery module supports up to 15 units in parallel, expanding total capacity to 115.2kWh.

The battery module has a maximum continuous charge/discharge current of 70A (≈3.6kW). The system can handle short-term (＜1 minute) peak currents of 150A to start high-surge appliances. For daily operation, we recommend staying within 70A to maximize battery lifespan.

Standard charging temperature range is 0°C ~ 55°C. However, as an OEM/ODM option, we offer a battery preheating function (heating film or self-heating cells) that enables charging down to -20°C – ideal for off-grid systems in cold regions.

It has two independent MPPT channels. Each PV input supports up to 6kW (200–550V), for a total of 12kW of solar array power. Each MPPT also handles 4.5kW (9kW total MPPT power). Mixed solar arrays with different orientations or specifications can be connected.

Yes. Although designed as a pure off-grid inverter (no grid feed-in), the AC input port accepts 100/127V or 200/254V from the grid or a generator as a backup charging source. This feature is disabled by default but can be enabled by the OEM customer. The system can also send a generator start signal automatically when battery voltage drops below a set threshold.

We offer full customization in:

  • Enclosure color, finish, branding (logo, packaging, manual)

  • Baseboard LED lighting (color, pattern, brightness, alert modes)

  • BMS parameters, communication protocols (CAN, RS485, Bluetooth/Wi-Fi), and battery cell options

  • Off-grid & split-phase inverter logic (power allocation, AC voltage/frequency, PV/mains priority, generator signal)

  • Low-temperature battery preheating function

  • Wall-mounting brackets, anti-theft design, and cable management

  • Firmware, LCD language, and remote monitoring platform branding

The system carries CE (EMC/LVD), RoHS, UN38.3 (transport), and MSDS. Additional certifications (e.g., UL9540, UL1973, VDE2510) can be arranged for OEM orders. Warranty: 5 years or 4,000 cycles for the battery (whichever comes first), and 3 years for the inverter and controls. Remote troubleshooting, modular replacement, and local service partner support are available for bulk orders.

Whole system: 1100 mm (H) × 700 mm (W) × 120 mm (D) ; weight 80 kg. Recommended installation height: 10–15 cm above the floor for optimal baseboard lighting. Battery module alone: 1122 × 115 × 560 mm ; weight 63 kg.
