Factory-direct customization with complimentary design support for global partners.

99.99% Device Compatibility

Designed to integrate smoothly with common home energy and solar ecosystems.

Applications

Large Off‑Grid Homes & Multi‑Family Dwellings

Homes with electric cooking, multiple refrigerators, and home offices need more than 16kWh. This 32.15kWh system provides 2‑3 days of autonomy for essential loads, or a full day of heavy usage. The 6kW inverter runs central AC, well pump, and workshop tools simultaneously. Distributors targeting rural luxury homes or eco‑villages will appreciate the drop‑in upgrade from smaller units – identical floor space, higher capacity.

Small Hotels & Eco‑Lodges

Remote lodges with 5‑10 rooms require reliable power for lighting, fans, water pumps, and kitchen equipment. This system’s 32.15kWh stores enough energy for overnight operation, while 99.5% MPPT efficiency reduces required solar array size. The 150A charge current allows rapid daytime recharging. For OEM customers, we can add dual AC inputs (grid + generator) and logo branding on the LCD.

“Long Autonomy” SKU for Cloudy Climates

In regions with frequent overcast days, customers need extra battery capacity to bridge multiple low‑sun periods. This 32.15kWh unit offers double the storage of standard 16kWh systems while maintaining the same 6kW inverter power – perfect for markets where runtime matters more than peak output. Identical communication protocols (CAN, RS485, WiFi) simplify inventory and installer training.

Frequently Asked Questions (FAQ)

Total energy is 32.15kWh. With LiFePO₄ chemistry and BMS protection, you can safely use over 90% (≈29kWh) per cycle. For a typical home consuming 10‑15kWh/day, this provides 2‑3 full days of backup without solar input.

It depends on your peak load. 6kW continuous (12kVA surge) can handle:

  • 3‑ton central AC (≈3.5kW running, 7‑8kW surge)

  • Electric water heater (4.5kW)

  • Refrigerator (200W)

  • Lighting, TV, computers (500W)

  • Well pump (1.5kW)

If your home has electric oven, dryer, or larger AC, check your simultaneous load. For higher power needs, multiple units can be paralleled.

  • Max PV open circuit voltage: 500Vdc

  • MPPT working range: 120‑450Vdc

  • Max MPPT power: 9000W

  • Max charging current: 120A (from PV)

Example: 20× 450W panels (9000W total) wired as 10S2P (≈400Vdc) works perfectly. You can oversize PV within voltage limit – the MPPT will limit power to 9000W.

Yes. Up to 6 units can be paralleled (192.9kWh total, 36kW total output) via CAN/RS485 communication. The built‑in BMS supports master‑slave configuration. Contact us for parallel kits and wiring diagrams.

Typical <10ms (milliseconds). This is fast enough to prevent reboot of computers, servers, and sensitive electronics. The inverter operates in off‑grid mode with seamless transition.

The standard version operates from -10°C to +60°C. For regions below -10°C, we offer an optional self‑heating function (BMS‑controlled heating pad) as an OEM customization. Please specify when ordering.

Standard: CAN, RS485, WiFi (2.4GHz), USB. The RS485 port supports Modbus RTU protocol. We can provide protocol documents for system integrators to connect with SCADA, generators, or energy meters.

150A at 51.2V equals ≈7.68kW. This matches the 6kW inverter output plus some margin. For AC charging from grid/generator, you can adjust current from 2A to 120A via LCD or APP – compatible with smaller generators (e.g., 3kW) by limiting current.

  • Dimensions: 580×580×938 mm

  • Weight: ≤253 kg

  • IP20 rating – indoor use only (garage, basement, utility room)

  • Floor standing recommended (wall mounting not advised due to weight)

  • Clearance: 200mm on sides and top for ventilation

  • Operating temperature: -10°C to +60°C

We recommend professional installation by a certified electrician.

≥6000 cycles at 25°C, 0.5C charge/discharge, 70% capacity retention (end of life). Standard warranty: 5 years.  We offer batch test reports. Cells are Grade A, brand new LiFePO₄ from tier‑1 suppliers.

Yes. The AC input (grid/generator) and PV input work simultaneously (hybrid charging). You can set priority via LCD or APP: solar first, grid/generator as backup. The AC charging current is adjustable to match generator rating.

Absolutely. As an OEM/ODM factory, we offer:

  • Logo on front panel and LCD startup screen

  • Custom packaging (color box, foam, pallet labeling)

  • White‑label mobile APP (your brand name, icon, and colors)

  • Custom user manual and specification sheet in your brand language

MOQ for basic logo branding: 100 units. Sample orders (1‑2 units) available. Contact us for a quote based on destination port.
