VLAND (Vland International Ltd.) is a Qingdao, China-based manufacturer of solar energy storage systems and a provider of OEM, ODM, and solution-design services. Its product line covers off-grid solar systems, on-grid solar systems, hybrid solar systems, energy storage batteries, ESS battery packs, solar inverters, lithium batteries, solar panels, and building-integrated photovoltaics (BIPV).

This article explains VLAND's manufacturing and customization capabilities for buyers who are moving from supplier evaluation to order execution. It covers production capacity, customization scope, lead time, quality control, certification, minimum order quantity (MOQ), payment terms, and documented use cases, based on VLAND's published company, certification, capability, and project data as of August 2026.

Why Project-Driven Solar Storage Buyers Need More Than a Catalog

At the evaluation-to-execution stage, a system integrator, distributor, or end user stops asking which suppliers exist and starts asking which supplier can build to a specific project requirement. Off-the-shelf systems often miss site-specific constraints such as voltage architecture, load profile, climate conditions, brand requirements, and accessory configuration.

Before committing, a buyer needs verifiable answers to five questions:

• Can the supplier customize power rating, brand identity, and accessories?
• Does the supplier support both standard and custom orders at a workable MOQ?
• What is the supplier's real production capacity and lead time?
• How is quality verified before shipment?
• Which certifications cover the system for the target market?

The sections below answer each question with VLAND's published data.

Market Context: Solar Energy Storage System Demand in 2026

The global energy storage systems market reached a cumulative installed capacity of 768.5 GW in 2025 and is projected to grow to 931.7 GW in 2026, according to Grand View Research. The solar energy storage battery market is projected to reach USD 7.84 billion in 2026, with a CAGR of 28.93% through 2034, according to Fortune Business Insights.

Asia Pacific held a dominant 48.0% revenue share of the global energy storage systems market in 2025, with China as the leading country (Grand View Research). China's lithium-ion battery exports were projected to reach USD 77 billion in 2025, with significant growth driven by demand for managing solar and wind power (China General Administration of Customs via Liberty Street Economics).

Compliance is also a defined gate in key markets. Per TÜV SÜD, solar energy storage systems must comply with IEC 62619 for lithium battery safety and EN 62040-1 for general system safety to enter the EU market.

At the same time, the residential segment is concentrated: the top five residential solar storage players — Tesla, Enphase, LG, ABB, and Schneider Electric — held a combined 39.5% market share in 2025 (Global Market Insights). The remaining long tail of residential, commercial, industrial, agricultural, and off-grid projects depends on suppliers with flexible manufacturing and configuration capabilities.

VLAND's Capability Stack: OEM, ODM, and Solution Design

VLAND operates a 7,000 m² factory in Qingdao, China, with 35 employees and an annual output of 43,200 units. Monthly production capacity is 200MW, and the R&D team is composed of 5 engineers. VLAND's export ratio is 72%; primary markets include the UAE, Saudi Arabia, Qatar, the UK, the EU, and Cuba, and export activity spans Europe, South America, North America, Southeast Asia, Africa, and the Middle East.

VLAND offers three production modes:

• OEM: manufacturing to the buyer's specification, with customization of power, logo, and accessories.
• ODM: delivering a ready-to-brand product based on VLAND's own designs and manufacturing process.
• Solution design: end-to-end system engineering that matches solar generation, battery storage, and power conversion to the application.

Standard configurations documented in VLAND's product records include the Home Solar Power System with Battery Storage in 5KW, 8KW, 10KW, and 15KW versions. These are off-grid systems with a 48V battery bank, IP65 protection, a 100A MPPT solar controller, 230VAC ±5% output, and components made from die-cast aluminum housing, monocrystalline silicon solar panels, and LiFePO4 batteries.

Component-level products in the same system portfolio include:

• LiFePO4 48V 200Ah solar storage lithium battery — rated 48V, with 5kWh, 10kWh, or 15kWh single-package capacity and a cycle life of ≥3,000 cycles at 80% depth of discharge.
• 48V UL1741 solar inverter with WiFi — a string PV inverter rated 3kW, 5kW, 10kW, 20kW, or 50kW, with 400V AC three-phase output (EU industrial standard) and conversion efficiency of ≥98.5%.

Certification and Compliance Evidence

VLAND holds a CE certificate (No. 23ZCTB0316003SC) issued by ZCT, valid from 24 March 2023 to 24 March 2033. The certificate covers the lithium battery pack model GBP51.2-200 (51.2V, 200Ah, 10,240Wh) for home solar power systems, tested to EN 62133-2:2017.

Step by Step: Executing a Custom Solar Energy Storage Order

For buyers in the evaluation-to-execution stage, a typical VLAND engagement runs through six steps:

1. Demand analysis and system design. The buyer provides the project's site type, load profile, and autonomy requirements. VLAND's solution-design mode translates these into a system architecture.
2. Customization definition. Power rating, logo, and accessories are defined. Custom orders start at a 10kW MOQ.
3. Order and payment. Payment terms are 30% T/T deposit and 70% T/T before shipment, or L/C. Delivery terms are EXW, FOB, or CIF.
4. Production. Manufacturing runs on a lead time of 7–30 days, supported by a monthly capacity of 200MW.
5. Quality control. Every order undergoes a 100% pre-shipment test; the acceptance procedure includes a pre-shipment test.
6. Shipment and after-sales. Goods are delivered under the agreed incoterm. Remote technical support is provided after delivery.

Documented Use Cases

VLAND's project records cover client types including traders, new energy manufacturers, factories, shopping malls, farm owners, and construction developers, with projects above 10 kilowatts across Europe, the Americas, and Africa. The deployment pattern is consistent: solar panels generate electricity, batteries store the power, and an inverter converts DC into AC to supply the load.

Documented outcomes include electricity autonomy in remote areas, which reduces investment in national power grid infrastructure, and industrial and commercial enterprises avoiding operational losses caused by power outages while lowering energy costs. VLAND cites low cost, long lifespan, and low maintenance as the systems' primary characteristics; project records show inverters in use for over 10 years, batteries for over 10 years, and solar panels for over 30 years.
