Our inverters and energy storage products are mainly involved in the following application areas:

1. Residential Solar Power Systems: These renewable energy products can be used in residential solar power systems to convert the DC power generated by solar panels into AC power that can be used to power household appliances. PV-string inverters are commonly used in such systems.

2. Small Commercial/Industrial Solar Power Systems: Similar to residential systems, renewable energy products are used for commercial or industrial applications. String inverters or centralized inverters may be used, depending on the project size and requirements.

3. Wind Power Systems: Wind turbine Grid-tie inverters are used in wind power systems to convert the variable DC power generated by wind turbines into stable AC power that can be fed into the grid or used locally.

4. Hybrid Power Systems: Hybrid inverters are utilized in hybrid power systems, which combine multiple renewable energy sources such as solar and wind, along with other energy storage systems. These inverters manage the integration of various energy sources and storage to provide a reliable power supply.

5. Off-Grid Systems: Inverter plus battery all-in-one units are commonly used in off-grid systems, where renewable energy sources like solar or wind power are used to generate electricity that is stored in batteries for later use.  These units convert DC power from renewable sources into AC power for use by appliances.

6. Energy Storage Systems: Inverter plus battery all-in-one units play a vital role in energy storage systems, where excess electricity generated from renewable sources is stored in batteries for later use, such as during periods of low generation or high demand.

Overall, these renewable energy products have diverse application areas, ranging from residential and commercial settings to off-grid environments and specialized industries. They contribute to energy efficiency, cost savings, grid stability, and the integration of renewable energy sources.

Product quality assurance. Quality is mainly maintained from the following aspects: 

1. Incoming Materials: According to the sealed sample parts, IQC conducts inspections on material appearance and specifications to check the material parameters and records incoming inspection data. The main use of equipment: Wheatstone Bridge, Voltage meter, Transformer tester, etc..

2. Production: Torque efficiency inspection 3 times per day. Weekly quality control meetings to go over points of improvement. Each product has a process card and a separate SN number, which can be traced back to the operator and production time.

3. Testing process: Including but not limited to board test/initial test of the whole unit/finished product aging test. Defective products appearing in each procedure should be written on the defective product card, describing the exact root cause. Maintenance of the defective product card will fill in the maintenance content and quality recovery logs.

4. Finished product inspection: Before the shipment, OQC conducts sampling inspections on product performance, product appearance, and product accessories.

When we quote for you, we will confirm with you the way of transaction, FOB, CIF, CNF, etc.

For mass-production goods, you need to pay a 30% deposit before producing and a 70% balance against a copy of documents. The common way is by T/T. L/C is also acceptable.
