Photovoltaic Storage System Project

Project Overview
This project is located in Spain. The photovoltaic storage system comprises a 30KW photovoltaic inverter and an 86KWh energy storage battery, forming an off-grid photovoltaic storage system. It is equipped with nine 550W photovoltaic panels. The system meets the client’s current requirement for no mains electricity supply, while also incorporating a hybrid grid-tied/off-grid mode to accommodate future mains electricity connection needs.



  1. Project Specifications

Applications

Off-Grid Standby Mode: During mains power outages or absence, the photovoltaic system supplies loads and charges the storage batteries when operational. When PV generation is insufficient or unavailable, the storage batteries power loads until battery capacity falls below 10%, at which point the system enters standby or shutdown mode until PV generation resumes.

 

Grid-Connected Hybrid Mode (Reserved Functionality): A backflow prevention device is installed on the AC input side of the PV inverter to enable grid connection of the PV generation. In this mode, the system connects to the grid when mains power is available, ensuring priority use of PV power for self-consumption. Future upgrades will enable the sale of surplus PV electricity to the grid as required.

Core products

Fiber Optic Pigtail
Fiber Optic Pigtail

Fiber Optic Pigtails have a pre-terminated connector on one end and a bare or tight-buffered fiber on the other for fusion splicing into fiber distribution systems. This series features a 12-core bundle design using G652D single-mode fiber with internationally color-coded jackets (yellow). Multiple connector types (SC/LC/FC/ST) and polishing options (UPC/APC) are available. The 0.9 mm tight buffer provides effective fiber protection with good flexibility for easy termination and routing.

FTTH Drop Cable Patch Cord
FTTH Drop Cable Patch Cord

FTTH Drop Cable Patch Cords (Butterfly/Drop structure) are essential access products in Fiber-to-the-Home systems, featuring a flat butterfly-shaped design with 1~4 cores of bend-insensitive G657A1/A2 single-mode fiber. Integrating cable and connector into one assembly, these cords can be directly routed through building hallways, indoor conduit shafts, or overhead outdoor installations - with excellent mechanical performance and easy installation - making them the standard last-100-meter solution for fiber broadband networks.

Fiber Optic Patch Cord – All Models Combined
Fiber Optic Patch Cord – All Models Combined

Fiber Optic Patch Cords are pre-terminated fiber optic cables used for equipment interconnection, test connections, and link extensions in optical communication systems. This product series covers Single-Mode (SM) and Multimode (MM, OM3/OM4) categories, supporting FC, LC, SC and other mainstream connector types with UPC and APC polishing options in both Simplex and Duplex configurations. All products use G652D/G657A single-mode or multimode fibers with low insertion loss, high return loss, and excellent repeatability. Suitable for FTTH, data centers, LAN, and CATV applications.

ODVA Waterproof Remote Fiber Patch Cord
ODVA Waterproof Remote Fiber Patch Cord

ODVA Waterproof Remote Fiber Patch Cords are purpose-built for harsh outdoor environments, featuring ODVA-standard waterproof connectors (Mini SC / OptiTap interface) with IP68 waterproof and dust-proof ratings. Designed for FTTA (Fiber to the Antenna) base station remote connections, FTTH outdoor drop applications, and industrial outdoor fiber access, these cords withstand extreme temperatures, UV radiation, and mechanical vibration - the ideal choice for outdoor fiber network deployment.

MPO Fiber Optic Patch Cord
MPO Fiber Optic Patch Cord

MPO Fiber Optic Patch Cords are high-density multi-fiber connector assemblies built to the MPO (Mechanical Push-On) standard interface, supporting 8 to 144 cores for parallel transmission. Compared to conventional single-fiber LC/SC patch cords, MPO cords deliver several times the fiber density in the same footprint, dramatically reducing cabinet space in data centers, HPC facilities, and FTTH networks running 40G/100G/400G links.
