About Domy New Technology (shenzhen) Co., Ltd - Solar Power Equipments and Batteries Supplier in China

Domy New Technology (shenzhen) Co., Ltd is a China-based supplier registered in Shenzhen, Guangdong Province, operating with 25 active listings concentrated in two closely linked categories: Solar Power Equipments and Batteries & Chargers. Its catalogue is built around portable energy storage systems and portable solar stations, with battery capacities ranging from 10.24 kWh to 25.6 kWh paired with inverter outputs of 5 kW, 6 kW and 8 kW. The supplier also lists a lower-wattage line of portable solar stations from 600 W to 2.5 kW and a series of portable solar folding charger packages from 60 W to 300 W, covering both off-grid household backup and outdoor/mobile power use cases. The product mix reflects the broader shift in southern China's electronics manufacturing corridor toward modular, lithium-based energy storage paired with photovoltaic input. The core of the catalogue sits in HS code family 8507.60, which covers lithium-ion storage batteries, and the listed materials consistently identify Lithium Iron Phosphate (LiFePO4) chemistry, with one model noting LiFePO4 / NMC options. The larger 5 kW to 8 kW units are described as portable storage energy stations with integrated inverter functions, while the smaller 600 W to 2.5 kW units are positioned as portable solar stations, and the 60 W to 300 W items are folding charger packages designed for direct photovoltaic input. Together these 25 listings map a complete product chain from small-scale solar charging kits up to multi-kWh home and small-commercial backup systems, all originating from a single Shenzhen-based supplier.

Product Range and Specialties of Domy New Technology (shenzhen) Co., Ltd

The supplier's catalogue divides into three practical tiers. The first tier is the 5 kW to 8 kW portable storage energy station family, with battery capacities of 10.24 kWh, 15.35 kWh, 20.48 kWh and 25.6 kWh, all built on LiFePO4 cells and housed in steel-aluminum enclosures; several models integrate the inverter directly into the unit. The second tier is the sub-3 kW portable solar station segment, covering 600 W, 1.2 kW, 2.0 kW and 2.5 kW outputs aimed at camping, RV and light off-grid use. The third tier is the portable solar folding charger package line, scaling from 60 W up to 300 W in defined steps (60 W, 60 W Type B, 80 W, 100 W, 120 W, 160 W, 200 W, 300 W), which are typically monocrystalline or polycrystalline panel arrays with foldable designs and USB/DC outputs. Within the portable energy storage category, LiFePO4 has become the dominant chemistry for stationary and semi-stationary units because of its thermal stability, cycle life commonly rated at 2,000 to 6,000 cycles at 80 percent depth of discharge, and lower fire risk compared to NMC variants. Buyers in this segment typically compare products on continuous inverter output (kW), peak/surge rating, battery capacity in kWh, round-trip efficiency (often quoted in the 85 to 95 percent range), charge and discharge rates (C-rate), and the number of AC outlets, DC ports and USB ports. For solar folding panels, the relevant parameters are panel wattage, open-circuit voltage, conversion efficiency (typically 19 to 23 percent for mono cells), folded versus deployed dimensions, weight, and IP rating for outdoor use. The supplier's range covers the full wattage ladder that buyers in this category expect, from pocket-size 60 W panels up to 25.6 kWh home backup stations.

Trade and Export Information - Domy New Technology (shenzhen) Co., Ltd

Portable energy storage systems and solar folding panels fall under several HS code families depending on configuration: lithium-ion battery packs are classified under 8507.60, while complete portable power stations with integrated inverter may be classified under 8504.40 (static converters) or 8501.31 / 8501.32 depending on the importing customs authority's interpretation. Solar folding panels typically fall under 8541.40 (photovoltaic cells) or 8541.43 when assembled in modules. China is the world's largest exporter of both lithium-ion battery cells and finished portable energy storage products, with Shenzhen and the wider Guangdong cluster acting as a primary manufacturing and export hub, shipping through Yantian, Shekou and Shenzhen ports. Typical buyers of these goods include distributors serving the off-grid residential and small commercial backup market in North America, Europe, Australia and Africa, as well as outdoor and RV brands, humanitarian and field-operation buyers, and emerging-market retailers addressing unreliable grid supply. Common documentation and certification requirements for this category include UN 38.3 for lithium battery transport, MSDS (Material Safety Data Sheet), CE marking for the European Union, FCC for the United States, RoHS for hazardous substance compliance, IEC 62619 or UL 1973 for stationary lithium battery safety, and IEC 62109 for power converter safety; many buyers also require IEC 61215 or IEC 61730 for the PV modules. Sea freight in 20 ft and 40 ft containers is standard for the larger 5 kW to 8 kW units, with each unit typically packed in an individual export carton on pallets, while smaller folding panels and sub-3 kW stations often move by air for faster replenishment. Standard Incoterms in this trade are FOB Shenzhen, CIF and occasionally DDP for buyers requesting door delivery.

Sourcing from Domy New Technology (shenzhen) Co., Ltd - Buyer Guidance

Buyers approaching this supplier should first confirm the exact battery chemistry, cell origin (whether prismatic, cylindrical or pouch), and the rated cycle life at a stated depth of discharge, since LiFePO4 cells from different tier-one and tier-two manufacturers vary significantly in calendar life. It is standard practice to request the UN 38.3 test report, MSDS, IEC 62619 or UL 1973 certificate for the battery pack, IEC 62109 for the inverter section, and CE / FCC / RoHS declarations depending on the destination market. For the solar folding panels, ask for the IEC 61215 and IEC 61730 reports and confirm the IP rating of the junction box and connectors. Before placing a production order, buyers typically request a pre-shipment sample for independent capacity testing (verifying the actual kWh against the rated figure), a drop test report for the housing, and a thermal runaway or nail penetration test for the LiFePO4 pack. Confirm the BMS (Battery Management System) protections listed, including over-charge, over-discharge, short-circuit, over-temperature and cell balancing functions, and verify the communication protocol if integration with existing solar inverters is intended. For shipping, request the Class 9 dangerous goods declaration for lithium batteries and confirm whether the supplier can arrange DDP terms or only FOB / CIF from Shenzhen. A harbor-tier supplier with 25 active listings in this niche is best suited for buyers who are comfortable performing their own technical due diligence and who want access to a broad wattage ladder from a single source rather than a fully certified white-label partner.
