PV Grid-connected Box

The SYPV3 PV Grid-connected Box supplied by China manufacturer Zhejiang Soutya New Energy LLC, is primarily used in residential photovoltaic distributed grid-connected power generation systems and small commercial photovoltaic power generation systems, located between the grid inverter and the power grid. It features a series of protections, including anti-islanding, pressure interlock tripping, under-voltage, over-voltage, input lightning protection, system overcurrent, and grid isolation. It provides accurate energy metering, transmission, and intelligent operation control, making it an essential component of residential grid-connected power generation systems.

Characteristic

1.Reserved installation space for metering instruments and data collectors.
2.Visibility window for metering instruments and lead-sealed ports (anti-theft)..
3.The integrated design concept completely isolates the distribution part from the metering part, reducing electromagnetic interference.
4.Various self-resetting over/under voltage protectors and photovoltaic-specific reclosers are available to meet the usage requirements and acceptance standards of different regions.
5.The box cover requires a specialized key for access, ensuring professional management.
6.Designed for outdoor installation, enhancing safety.
7.Supports customization for special requirements and functions.

Technical Parameters

Application scenarios

1. Residential Rooftop PV – Provides utility-grade metering, overload & RCD protection, and lockable AC isolation for single-phase 3–10 kW household systems, speeding up utility inspection and feed-in approval.

2. C&I Flat-roof Installations – Delivers integrated MCB/RCBO/SPD and bi-directional smart meter in one IP66 aluminium box, cutting onsite assembly time on 20–60 kW three-phase commercial rooftops.

3. Agricultural & Greenhouse Solar – Withstands ammonia, dust and hose-directed water thanks to the die-cast enclosure, safeguarding reliable disconnection and revenue metering for 15–50 kW agrivoltaic strings.

4. Car-port & EV-charging Integration – Compact footprint and front-access terminals allow wall-mounting beside chargers; the internal Type 2 SPD and RCBO protect both inverter and EV supply equipment from grid-borne surges and earth faults.

5. Modular Ground-mounted Arrays – Pre-wired busbars and plug-and-play CT meter enable rapid parallel deployment of multiple 30 kW blocks, giving EPCs a repeatable, utility-compliant AC combiner solution for small solar farms.
