Import 6kw 15.35kwh Portable Solar Storage System — Buy in wholesale FOB from Supplier in China

The Domy 6KW 15.35KWH Portable Solar Storage System integrates a 6KW hybrid inverter with a 51.2V 300AH lithium iron phosphate battery pack, configured as three 51.2V 100AH mini-units in parallel. The system supports both off-grid and on/off-grid hybrid operation, with high-frequency or low-frequency hybrid inverter options and an integrated MPPT controller. Output is pure sine wave at 220V (European), 110V (American), or 100V (Japanese) depending on destination, with single phase output and paralleling capability up to 9 units. The built-in battery management system monitors cell voltages and temperatures, and the unit includes an LCD screen for battery and usage status indication.

The LiFePO4 cathode chemistry offers standard cycle life of 4000+ cycles and a 10+ year calendar life claim, with inherent thermal stability advantages over NMC or LCO chemistries at the cell level. The high-frequency inverter option provides lighter weight and higher conversion efficiency for portable applications, while the low-frequency option offers greater surge capacity for motor starting loads. The MPPT controller handles PV input through the same port as AC input, eliminating separate wiring. UPS functionality is not included in the base specification (no adapter with UPS function), so transfer time during grid failure must be confirmed for critical load applications. The wheeled mobile design allows indoor or outdoor placement, though IP rating for outdoor use is not stated.

Target applications include residential backup power, small office continuity supply, and off-grid installations where solar direct-drive daytime operation supplements battery discharge. The system can operate without battery, routing solar directly to AC loads during daylight hours, with excess charging the battery or feeding to utility in on/off-grid mode. OEM and ODM customisation is available, including output voltage configuration and branding. The 5 year inverter and 10 year battery warranty claims exceed typical industry practice, though warranty terms, conditions, and claim procedures require direct confirmation with Domy. RS485 and USB communication ports allow external monitoring system integration.

Domy New Technology (shenzhen) Co., Ltd operates from F3, Block 2, Yaochuan Industry Area, Yongfu Road, Fuhai Street, Baoan District, Shenzhen, 518103, Guangdong Province, China. The supplier holds a harbor trust tier on the platform, with a 0.00% response rate and no recorded average response hours, indicating minimal engagement data is available. The company focuses on integrated energy storage systems with hybrid inverter technology, offering both standard configurations and customised OEM/ODM services for international markets.

The Shenzhen location places Domy within the Pearl River Delta electronics manufacturing cluster, with access to cell suppliers, PCB assembly, and inverter component ecosystems. The listing does not disclose when the company was established, factory floor area, annual production capacity, number of employees, or revenue figures. No specific export markets, reference installations, or third-party certifications (such as IEC 62040, UL 1973, or UN38.3) are mentioned. Buyers should request company registration documents, factory audit reports, and product test certificates before placing substantial orders, particularly given the high value and safety-critical nature of lithium battery energy storage systems.
