Generation, conversion, storage, and intelligent energy management in one loop.

Components—and systems built around your site

Energy challenges differ by region and application. We supply tier-one modules, hybrid and grid-tied inverters, and LFP storage—then engineer the right combination for your load, grid conditions, and budget.

Our scope covers generation, conversion, storage, and intelligent management so you work with one partner from discovery through after-sales support. We are committed to high-efficiency lithium battery solutions and integrated systems that connect storage with smarter energy use—using advanced technology and eco-friendly materials to deliver performance, energy density, and sustainable value.

What we stand for

Reliability & value

Long-term stable operation for customers and projects—not short-term spec-sheet wins.

Real customization

Layouts shaped by consumption data, goals, and local grid conditions—not a one-size-fits-all SKU stack.

Global partnership

Cross-border delivery experience to reduce compliance, logistics, and commissioning risk.

Sustainability

Cleaner power, lower carbon footprint, and smarter energy use across the project lifecycle.

Full lifecycle support

From discovery and design through delivery, installation guidance, and after-sales service.

Why customers choose us

A one-stop approach to cost reduction and stable power supply.

Partner ecosystem

Rongkai integrates tier-one industry brands across PV, inverter, storage, and BOS projects—we are an integrator and export partner, not the sole manufacturer of every SKU. Confirm model, warranty, and certification with sales per project.

Module partners

JA Solar, LONGi, JinkoSolar, Trina Solar, Aiko, Astronergy, TCL, Sungrow, Tongwei, GCL SI, and others.

Inverter partners

Deye, Growatt, Solis, Huawei, GoodWe, Sungrow, SAKO, Techfine, Canadian Solar, TBEA, Colasolar, and others.

Turnkey solar + storage

Residential and C&I projects can combine high-efficiency PV, the right inverter architecture, and scalable LFP storage in one coordinated scope.

Turnkey residential PV + storage can reduce energy costs by up to 35% in suitable project scenarios; final savings depend on tariff, load profile, and local policy.

PV modules

Capture solar efficiently—N-TOPCon, bifacial gain, half-cell, and extended warranty themes from our module partners.

Inverters

The system hub for real-time energy management, export control, and hybrid dispatch.

Energy storage

Store daytime surplus for night use, peak periods, or backup when the grid is weak.

Inverter types

Grid-tied — High-efficiency grid connection; maximize returns where net metering applies.
Hybrid — PV + storage integration with intelligent dispatch and backup paths.
Off-grid — Independent power and reliable backup for remote or weak-grid sites.

Storage pillars

Safety — BMS protection, cell technology, and controlled charge/discharge for stable operation.
Long life — >6,000 cycle class designs; 10+ year service themes; low degradation when properly sized.
Scalable — Modular architecture from residential kWh through C&I and MWh-class expansion.
