Application:Photovoltaic grid-connected boxes are used to build photovoltaic power stations near the users site. The operation mode is based on theuser's spontaneous use and excess power to go online: in order to maximize the safe operation of the system, ensure the safe coordination ot"he inverter and the mains nower grid. and improve Photovo taic grio-connected distribution box designed tor svstem relability and energmetering, The proouct nas the characteristics of high protection eve . ong service ife and convenient insta lation and oneration lts function.include isolation protection, overload protection, short circuit protection, surge grounding protection, over and under voltage protection andreclosing after restoration, power generation electricity metering, etc.

1.A meta boxes are made ot co -ro ed stee or stainiess stee plates produced oy Wunan ron and Stee., and the protection evel or the box above IP54, which is suitable for outdoor installation.
2. The box body adopts a thre-aver design, the top layer is designed as the frame of the box body to prevent rain and rainwater from enterinthe box body: the middle averis esigned as a photovo taic meter and various data on the meter can be observed througn the transparentglass plate , And a seal interface is designed on the door ock: the bottom laver is designed as a contro and protection area. which isconvenient for maintenance personnel to maintain and repair.
3. The grid inlet hole design of the box body can enter the wire from the bottom or the side. When the side wire enters, an lP66 waterproofconnector is installed to ensure the protection level of the box.
4. The inlet hole of the inverter is designed at the bottom to facilitate direct wiring on site..
5.The isolation switch in the box adopts a wel-known brand and has an obvious breaking point. The design capacity is more than 1.5 timesthemaximum output current of the inverter
6. The cabinet is designed with a photovoltaic over-voltage protection device and a voltage recovery reclosing protection device. n addition tovoltage loss protection, this product can also protect the grid voltage from instability.,
7.The cabinetis designed with heavy surge protection. The standard maximum discharge curent of the surge protector is 40KA. in areas witrrequent thunderstorms,a larger lightning surge protector can be used, and the maximum discharge current can reach 100KA.
8, The cabinet is designed with an over-curent protection circuit breaker to ensure that the circuit breaker can be reliably disconnected wherthe svstem is overloaded or short-circuited.
9. The installation board inside the box can be equipped with epoxy resin insulation board according to customer requirements, and thethickness of the insulation board is at least 5mm or more.
10. The anti-islanding device can be configured according to customer requirements.
