Backed by 12 years of energy storage R&D and OEM/ODM expertise, our production process employs automated laser welding for battery modules and double-layer anti-corrosion aluminum alloy cabinet forming, with every unit subjected to 72-hour continuous aging testing prior to delivery. The bundled BW-INV-SPH3.6KA hybrid inverter features three independent MPPT trackers, supporting a maximum PV DC input of 7.36kW across a 40–550V voltage range, perfectly matching the 3–7kW residential solar arrays commonly found in European and Australian markets.

The supporting 14.06kWh LFP battery stack (13.79kWh usable energy) utilizes automotive-grade lithium iron phosphate cells and incorporates six-dimensional safety protections, including overvoltage, overcurrent, thermal runaway, short circuit, reverse polarity, and insulation monitoring, fully complying with EU Regulation (EU) 2023/1542 on battery safety. With natural convection plus intelligent auxiliary air cooling, the system operates at under 30dB at one meter, allowing placement in garages, utility rooms, or covered outdoor balconies without disturbing daily life. Factory test data confirms a maximum system efficiency of 97.7% and European weighted efficiency of 97.0%, significantly reducing energy losses during PV charging and household discharge cycles.

PARAMETERS

Real Global Application Cases & User Usage Experience

ThisSinoah single-phase storage kit has accumulated thousands of successful residential installation cases across Europe, Australia and Southeast Asia. A typical real case comes from a suburban villa household in Melbourne, Australia, equipped with a 6kW rooftop PV system paired with our 3.6kW 14kWh Single Phase ESS Kit. Before installation, the family paid AU$720 quarterly on grid electricity bills, suffering frequent summer storm blackouts lasting 4–12 hours. After deploying the kit, intelligent EMS automatically stores excess daytime solar power for evening household loads (air conditioners, refrigerators, lighting and water pumps), lifting solar self-consumption rate from 32% to 91%. The quarterly electricity expenditure dropped to AU$160, and the 4ms seamless grid-backup switching function guaranteed uninterrupted power supply during three summer grid failures in 2025.

Another representative case is a rural detached house in southern Germany, where local TOU tariff differences reach €0.42/kWh. The homeowner activates peak-shaving and valley-filling modes via the system App, charging the battery with low-price off-peak grid power and discharging during expensive peak hours, earning around €190 monthly in energy savings. For small home office users (mini craft studios, online retail workrooms), the kit’s 3.6kW continuous backup output and 15kW bypass overload capacity support simultaneous operation of computers, printers and small heating equipment. Operation steps are extremely user-friendly: installers complete stacked plug-and-play wiring within1 hour, homeowners only need to connect WiFi to enter the mobile App, switch between self-consumption, backup priority and VPP participation modes with one tap, and view real-time power generation, battery SOC and grid interaction data anytime.

The system adapts to multiple grid standards including VDE-AR-N 4105, AS/NZS 4777.2 and CEI 0-21, so installers can deploy the same kit without hardware modification in different regional markets.

Raw Material & Production Craft Advantages 

As a vertical integrated energy storage manufacturer, we independently produce LFP battery cells, BMS boards and hybrid inverter mainboards, cutting intermediate markup while enabling full quality traceability for every 3.6kW 14kWh storage kit. The battery module uses 280Ah long-cycle lithium iron phosphate cells with ultra-low self-discharge rate, tested to maintain over 80% capacity after 8000 charge-discharge cycles, outperforming most competitors’ 5000–6000 cycle cells. The cabinet shell adopts 1.5mm thick galvanized steel with electrostatic spray coating, reaching IP66 ingress protection, resisting rain, dust and coastal salt fog corrosion, suitable for outdoor semi-open installation. The inverter mainboard uses imported industrial-grade power IGBT chips, with built-in Type II DC/AC surge protection, residual current monitoring and AFCI arc fault detection functions to eliminate fire risks from aging PV wiring. During production, each battery module undergoes three strict tests: cell sorting, high-low temperature cycle aging and hydraulic extrusion safety testing; each inverter passes PV reverse polarity, battery reverse connection and anti-islanding grid simulation testing.

All transport packages meet UN38.3 lithium battery transportation standards, with shockproof foam inner lining and wooden pallet outer packaging, avoiding damage during cross-border logistics. Unlike small trading companies that assemble third-party components, our factory holds complete IEC 62109, IEC 62619 and EMC certification test reports, all verifiable via official certification inquiry platforms, supporting customers’ local grid filing and market sales compliance.

Pain Point Comparison with Peer Competing Products

1. Addresses Four Major Pain Points Simultaneously

Most entry-level single-phase home storage kits on the market face four prominent pain points that our NeoVolt G4 series solves comprehensively.

-First, many competitors only provide IP54 protection grade, unable to adapt to humid coastal or rainy outdoor environments; our whole machine achieves IP66, expanding installation scenarios to unclosed outdoor balconies and garden utility sheds.

-Second, mainstream 3.6kW hybrid inverters only carry 2 MPPT trackers, limiting PV array layout flexibility; our model upgrades to 3 MPPT channels, supporting segmented installation of PV panels on different roof slopes without power generation loss.

-Third, rival battery stacks usually deliver only 6000 cycle life and 90% DoD, shortening service life and reducing available energy; our LFP system hits 8000 cycles and 98% usable depth of discharge, extending effective service life by over 3 years and improving daily usable stored energy by 8%.

-Fourth, most competing kits lack native VPP/FCAS compatibility, unable to join grid demand response programs for extra household income; our embedded EMS reserves standard VPP communication interfaces, allowing end users to participate in national virtual power plant projects to obtain additional subsidies.

2. Ten-Year Warranty, Flexible Capacity Expansion

In terms of after-sales warranty, many brands only offer 5–7 year battery warranties, while we provide a unified 10-year full-system warranty covering inverters and battery modules, greatly lowering distributors’ and homeowners’ long-term maintenance costs. The modular stacked design also brings unique scalability: users can add extra battery stacks later to expand capacity to 28kWh/42kWh without replacing the original 3.6kW inverter, avoiding one-time high investment for future energy demand growth.
