Solutions

System-level answers for buyers who know the job—not just the SKU.

Whether you are fitting out a building, expanding a regional catalog, or planning a hybrid microgrid, start here then drill into product specs.

Turnkey scope

Generation, conversion, and storage in one coordinated loop.

Henan Rongkai integrates PV modules, inverters, and LFP systems for residential through utility-scale export programs—matching turnkey project goals without forcing a single SKU stack.

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.

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.

Residential savings figures vary by market and tariff—confirm load profile, energy price, and incentive assumptions in your RFQ.

Available solution paths

Commercial Solar + Storage for Buildings

Reduce daytime energy cost and improve power resilience with a matched PV array, hybrid or C&I inverter, and scalable LFP storage—sized for offices, retail, logistics, and mixed-use sites.

A single technical thread from kW/kWh targets to product SKUs.Fewer revision cycles because storage and PV are sized together.
