Import 30kw Outdoor Inverter Ip54 Waterproof — Buy in wholesale FOB from Supplier in China

Zhejiang Sandi Electric's 30 kW outdoor inverter carries an IP54 ingress protection rating, allowing installation in exposed environments without additional enclosure. The unit converts 48 VDC battery storage to 220 VAC using pure sine wave output, suitable for off-grid solar arrays in regions with unreliable or non-existent grid infrastructure. An aluminium housing with copper windings and PCB electronics forms the core construction, with a black pure-aluminium radiator dissipating heat generated by the sixth-generation Mitsubishi IPM intelligent module. Maximum efficiency reaches 94 percent, with more than 85 percent maintained at the nominal 48 V input, while output voltage regulation stays within ±1 percent across the adjustable -40 percent to +20 percent range.

The inverter supports two soft-start modes: step-down voltage start and variable frequency start, selectable through the LCD to match load characteristics such as induction motors or compressor-driven equipment. Input voltage bands of 150-400 V, 300-600 V, or 400-800 VDC are factory or field selectable, enabling direct PV array coupling without mandatory external charge controllers when MPPT wide-voltage input is utilised. Protection covers short-circuit, overload, and over-temperature conditions. The LCD provides real-time DC input voltage, output frequency, phase voltage and current, bypass voltage, cumulative energy in kWh, temperature, clock, and fault codes. Service life is projected at 15 years or more under rated conditions, though actual longevity depends on ambient temperature, ventilation, and maintenance access.

Primary import markets include industrial solar farm operators, telecom infrastructure providers, and emergency power contractors serving remote mountain, island, pastoral, and border regions. The IP54 rating suits outdoor cabinet or pad-mounted installations where dust and water spray are present but submersion is not expected. Buyers should confirm whether the 220 V output is single-phase or three-phase, as the source mentions both 220 V and split-phase contexts inconsistently, and verify compatibility with local appliance standards. The absence of CSA or UL marking on this model, in contrast to the indoor SDP series, means buyers in North America must assess whether the IP54 variant requires supplementary certification or is destined for markets recognising CE or equivalent conformity assessment.

Zhejiang Sandi Electric Co., Ltd. maintains its registered address at Building 13-2 Botong Huigu, No. 66 Binhai South Four Road, Yueqing Economic Development Zone, Yueqing City, Zhejiang Province, 325600, China. The facility sits within a mature industrial cluster for electrical manufacturing, with access to component suppliers for aluminium extrusion, magnetics, and power semiconductor modules. The supplier holds a harbour trust tier, the entry verification level, and shows a 0.00 percent response rate with zero recorded average response hours, signalling that platform-mediated enquiries have not yet generated measurable engagement from this account.

The company produces off-grid and hybrid solar inverters under the SDP series banner, targeting export markets with models differentiated by power rating, enclosure protection level, and certification set. This outdoor IP54 variant appears positioned for tropical, arid, or coastal installations where cabinet integrity matters more than North American grid-interconnection compliance. The profile does not disclose ISO certifications, factory audit scores, annual output capacity, number of employees, or named reference installations. Buyers requiring supply-chain due diligence should independently verify business registration, tax status, and whether the aluminium housing is die-cast or extruded, as this affects corrosion resistance and thermal performance.
