Import 3000w 48v Dc To 120v/230v Ac Inverter Charger — Buy in Bulk from Supplier in China

The 3000W 48V DC to 120V/230V AC Inverter Charger from Shenzhen Sopower Technology Co., Ltd. converts 48 volt direct current from battery banks into stable alternating current at 120 volts or 230 volts, with a continuous output of 3000 watts. The unit delivers pure sine wave output, critical for powering sensitive electronic equipment without harmonic distortion or risk of damage. A notable feature is the 300 percent surge power capability, allowing brief delivery of up to 9000 watts to handle motor starting currents from refrigerators, pumps, or power tools. The built-in smart AC charger manages battery replenishment, with configurable output voltage and frequency settings to match regional grid standards or specific load requirements. This inverter charger targets off-grid solar installations, recreational vehicles, marine craft, and backup power systems for residential and light commercial premises.

The 48 volt nominal DC input suits standard battery configurations using four series-connected 12V lead-acid cells or 16 series-connected lithium iron phosphate cells (3.2V nominal per cell). Pure sine wave output with total harmonic distortion below 5 percent is typical for inverter chargers in this class, though buyers should request the exact THD figure and load testing methodology from the supplier. The smart charger function likely employs multi-stage charging (bulk, absorption, float) to optimise battery lifespan, but the specific charge profiles and compatibility with AGM, gel, or lithium chemistries need confirmation. Thermal management through forced air or natural convection, operating ambient temperature range, and ingress protection rating are not specified in the source data. The configurable voltage and frequency implies front-panel or software-based adjustment, yet the interface type (LCD, DIP switches, Bluetooth, or RS485) remains unstated.

Typical purchasers include solar integrators building off-grid kits, RV and boat manufacturers requiring OEM power solutions, and distributors serving the telecom backup and residential energy storage markets. The 3000W rating sits at a common threshold for whole-cabin power in marine applications or partial home backup during grid outages. Importers should note that the supplier mentions CE and ISO certifications in broad terms, but specific certificate numbers, testing laboratory accreditation, and scope of certification are absent from the listing. Buyers must verify whether the unit meets target market EMC and safety standards, such as EN 62040 for UPS applications or IEC 60950/62368 for IT equipment, depending on end use. The zero response rate recorded for this supplier suggests proactive follow-up will be necessary to obtain technical documentation and negotiate commercial terms.

Shenzhen Sopower Technology Co., Ltd. is located at 5 Floor, 5 Building, 2nd Industrial District, Bantian, Longgang, Shenzhen 518129, Guangdong, China. The company sits within Shenzhen's dense electronics manufacturing corridor, with access to component supply chains, PCB assembly houses, and logistics hubs serving Hong Kong and Yantian ports. The supplier tier is marked as imported, and the trust tier as harbor, which indicates a verified business entity but does not imply product-level certification or factory inspection. The response rate is shown as 0.00 percent with zero average response hours, signalling potential issues with active enquiry management or a recently established listing. Buyers should not rely on prompt automated replies and should plan for multiple contact attempts or engagement through a local representative.

The supplier's product focus appears to be power conversion equipment for renewable energy and mobile applications, with this inverter charger representing a mid-range residential/commercial unit. No information is provided about factory ownership, production lines, engineering staff size, annual turnover, or major clients. The mention of CE and ISO certifications lacks certificate numbers, accreditation bodies, or validity dates, so these claims require independent verification. The company address places it in a multi-tenant industrial district typical of Shenzhen's SME electronics sector, which may involve assembly rather than in-house component manufacturing. Prospective buyers should request a company profile, factory audit capability, and references from existing export customers before large commitments.
