Import 5kw 15.35kwh Portable Solar Storage System — Buy in wholesale FOB from Supplier in China

This all-in-one energy storage system combines a 5kW hybrid inverter with a 15.35kWh lithium iron phosphate battery pack in a single wheeled enclosure for portable deployment. The built-in battery consists of 51.2V 300Ah cells in a modular configuration using three 51.2V 100Ah mini-units, with a stated cycle life exceeding 4,000 cycles and a 10-plus year design lifetime. Output is pure sine waveform at 220V for European markets, with 100V and 110V variants available for Japan and American regions respectively. The integrated high-frequency or low-frequency hybrid inverter choice allows buyers to match switching topology to their load profile and audible noise tolerance.

A key operational feature is the ability to run without battery participation during daylight hours, routing PV array output directly to AC loads while simultaneously charging the battery with surplus energy. In on/off-grid hybrid mode, fully charged battery states allow excess solar generation to feed into the utility grid. The system includes an integrated MPPT controller and an LCD screen for battery state and usage status indication. Communication is handled through one RS485 port for inverter-to-battery linkage and two USB ports for monitoring or firmware updates. Protection functions include overload cut-off and over-voltage shutdown at 60V threshold on the DC bus.

Target buyers include residential installers seeking plug-and-play backup power, remote office operators, and mobile emergency service providers who need wheeled transportability. The paralleling capability up to nine units extends capacity to 45kW and 138.15kWh for light commercial micro-grid applications. Warranty coverage is stated as five years for the inverter and ten years for the battery, though buyers should confirm whether this is prorated, whether on-site service or replacement-only terms apply, and what documentation is required for claims. OEM and ODM customisation is offered, so specific output voltages, branding, and enclosure colours may be negotiable for volume orders.

Domy New Technology (shenzhen) Co., Ltd is located at F3, Block 2, Yaochuan Industry Area, Yongfu Road, Fuhai Street, Baoan District, Shenzhen, Guangdong Province, 518103, China. The company holds a Harbor trust tier, meaning basic business verification is on file. The response rate shows 0.00 percent with zero recorded average response hours, indicating either minimal inquiry volume or untested communication channels. Buyers should initiate contact to gauge responsiveness and technical competency before committing to large orders.

The supplier's product focus appears to be energy storage and solar hybrid systems, with this listing showing substantial technical detail including inverter topology choices, battery management system integration, and multi-voltage output options. No factory size, R&D headcount, or certification list is provided in the source profile. Shenzhen's Baoan District hosts numerous electronics manufacturers, giving access to component supply chains but also requiring careful supplier verification. Buyers should request ISO 9001, ISO 14001, or IEC 62619 battery test reports, and confirm whether Domy manufactures cells and packs in-house or sources from a tier-one cell vendor.
