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.

OEM&ODM Process

Phase 1

Confirm Requirements and Finalise the Solution

We collect all customer specifications: voltage, capacity, dimensions, communication protocol, etc. Then we decide if it is a pure OEM job (build exactly to your drawings) or an ODM job (we provide the design). We issue a clear BOM (bill of materials) and 2D/3D drawings for both parties to sign off, avoiding any later misunderstandings.

Phase 1
Phase 2
Phase 2

Procurement and Incoming Inspection

We purchase all materials according to the BOM: cells, enclosure, brackets, screws, wiring, BMS boards, etc. When goods arrive, we do sampling or 100% inspection. For cells, we measure voltage, internal resistance and check appearance. For structural parts, we check dimensions and hole sizes. Any non‑conforming items are rejected and never go into our warehouse.

Phase 3

Cell Sorting and Matching

We group cells from the same batch by voltage and internal resistance values. We then match cells with the closest parameters into one set (for example, if a string uses 4 cells, the voltage and resistance differences among those 4 must stay within our set limits). This directly affects how long the battery pack will last without performance decay.

Phase 3
Phase 4
Phase 4

Laser Welding and Module Assembly

We fix cells into holders, then laser‑weld the tabs (connectors). We do pull‑force tests on sample weld spots to check strength. After that, we fasten the welded sub‑modules into the enclosure or tray, using torque‑controlled tools to apply the correct tightening force.

Phase 5

BMS Installation and Wiring Connection

We mount the main BMS and slave boards in their designated positions, then plug in all voltage sampling wires and temperature sensors. We always have a two‑person verification of the wiring sequence – this prevents reverse connections that could burn the boards when we power up.

Phase 5
Phase 6
Phase 6

First High‑Voltage Safety Test

We apply high voltage between the positive/negative terminals and the enclosure to measure insulation resistance and withstand voltage. We check for any leakage or breakdown. If this test fails, the module goes back for rework immediately – it does not move forward.

Phase 7

High‑Temperature Standing and Self‑Discharge (K‑Value) Check

We place the modules in a 45 °C room for 24–48 hours. We measure voltage before and after the standing period, then calculate the daily voltage drop (K‑value). Units with excessive drop are rejected because they indicate internal micro‑shorts that could cause early failure later.

Phase 7
Phase 8
Phase 8

Charge/Discharge Aging and Capacity Calibration

We connect the modules to charge/discharge equipment and run several full cycles at the current specified by the customer. During the process, we record actual discharge capacity, charge/discharge efficiency, and the temperature/voltage differences among individual cells. If all data stay within our acceptance limits, we calibrate the final rated capacity. If not, we isolate and analyse the failed units.

Phase 9

Final Inspection, Labelling and Packaging

We re‑measure total voltage, internal resistance and insulation performance. We check appearance for scratches, gaps, or damaged screws. We attach a permanent nameplate (with serial number), UN38.3 hazardous‑goods label, and all required operation warning labels. Then we package the battery with foam or cardboard for shock protection, as per customer requirements, and record the final weight.

Phase 9
Phase 10
Phase 10

Shipment and Document Handover

We verify the shipping quantity, address and consignee. We prepare all accompanying documents: factory test report, MSDS, UN38.3 test summary, and transport condition certificate. We arrange pickup with our logistics partner, and after dispatch we send the tracking number and estimated arrival time to the customer.

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.
