Longi 630 photovoltaic panel specification

What is the application level of LONGi Solar module?

The application level of LONGi Solar module is Class II, which can be used in systems operating at > 50 V DC or >240 W, where general contact access is anticipated; When the modules are for rooftop application, it is necessary to take the overall fire rating of the finished structure as well as operation and maintenance into account.

How to calculate VOC in a Longi module?

(LONGi modules maximum system voltage is DC1000V/DC1500V---ac-tually system voltage is designed based on the selected module and inverter model.) The correction value of VOC can be calculated by the following formula. CVoc=1-βVoc×(25-T) T: The expected lowest temperature of the installation site.

What services does Longi offer?

LONGi offers professional consulting services, professional knowledge of PV power plant and charging station solutions, and full life cycle O&M capabilities. Uniform smart soldering increases the power and efficiency of the module, and improves the power load capacity.

Where should Longi modules be installed?

LONGi modules shall be installed on proper buildings or other appropriate places (such as ground, garage, building outer wall, roof, PV tracking system) but shall not be installed on any vehicles. Do not install modules at places that are possible to be flooded.

Do Longi modules corrode?

LONGi modules passed the IEC61701 salt spray corrosion test, but the corrosion may still occur on where the modules frame is connected to the bracket or where the grounding is connected. In case LONGi modules are installed ≥50m away from the ocean side, and related parts and components should be protected with anti-corrosion measures.

What size bolt tightener for Longi 30mm (30h) height frame module?

Suggestion :(1)M8 bolt tightening torque range: 12-16 N•m; M6 bolt tightening torque range: 8-12 N•m;(2)When using LONGi 30mm (30H) height frame module, it is recommended to select L ≤ 20mm length fasteners. (If there is a special model, consult LONGi customer service personnel); See details in Figure 8.
