pv panel junction box pre-potting type for 380w

PV-TY806: Integrated Pre-potted PV Panel Junction Box (15A&16A, ≤400W)

PV-TY806

TY806 is a high-reliability integrated (1-part) solar junction box designed specifically for standard crystalline silicon modules. Rated at 16A and suitable for panels up to 400W, this unit comes pre-potted from the factory, which means the soldering and sealing process is already finished before it reaches your production line. Simply solder it to the busbar and the module is ready — no on-site gluing, no curing time, and zero risk of air bubbles.

I. Why Choose PV-TY806 PV Panel Junction Box for Your PV Module

1. True"Solder-and-Go"Efficiency (Pre-potted Technology)
Unlike traditional empty pv panel junction boxes that require your staff to manually inject silicone and wait hours for curing, the TY806 is filled with high-thermal-conductivity silicone in a vacuum environment at our facility.

Eliminates Production Bottlenecks: Saves an estimated 3-5 minutes per solar panel in potting, curing, and cleaning processes.
Zero Bubble Guarantee: Machine potting ensures perfect adhesion to the diodes and terminals, eliminating the risk of partial discharge or overheating caused by air gaps.

2. Compact Integrated Design for Standard PV Modules
TY806 consolidates the bypass diodes and solar cable terminals into a single, low-profile housing.

Cost-Effective: Reducing the number of plastic parts and assembly steps lowers the overall Bill of Materials (BOM) cost for 400W-class solar panels.
Space-Saving: Its compact footprint is perfectly suited for standard 158mm/166mm cell layouts where backsheet space is limited.

3. Superior Environmental Protection (IP68)
The pre-potted structure locks all internal components into a solid, vibration-proof state.

Reliability: Provides stable performance under high humidity, salt mist, and extreme temperature cycling (-40°C to +85°C).
Material: Housing made of V0 flame-retardant PPO (Polyphenylene Oxide) ensuring long-term UV resistance and mechanical strength.

V. FAQ

Q1: What is the difference between a 1-part (integrated) and a 3-part (split) PV panel junction box?
A: A 1-part box, like the TY806, houses all three bypass diodes in one single compact enclosure. This is the most cost-effective and easiest-to-install solution for standard solar panels (≤400W). A 3-part pv panel junction box splits the diodes into three separate enclosures, which is necessary for high-power (500W+) solar panels to better dissipate heat. If you are producing standard residential solar panels, the TY806 integrated pv panel junction box is your best choice.

Q2: Will the pre-potted glue leak or melt during hot summers?
A: No. The TY806 uses a high-quality, heat-cured silicone gel. Once cured, it becomes a solid, rubbery substance (not a liquid). It will not leak or drip even at high operating temperatures. The pre-potting process actually creates a stronger vibration-resistant bond compared to manual on-site potting.

Q3: Is the TY806 suitable for bifacial (double-glass) modules?
A: We generally do not recommend using an integrated box like the TY806 for bifacial pv modules. Bifacial panels require pv panel junction boxes to be as small and low-profile as possible to avoid casting shadows on the backside of the cells. For bifacial or 500W+ high-power projects, we recommend exploring our 3-Part Pre-potted PV Panel Junction Box (TY001NEW) [product-3-split-pre-potted-solar-module-junction-box-1500v-25a-30a.html] or 3-Part Potting Type (TY002) [3-split-solar-panel-junction-box-1500v-25a-30a.html]

Q4: Do I need to inject potting glue into the TY806 after soldering?
A: No. This is the core advantage of the TY806. The"Pre-potted"designation means the potting process is 100% complete at the factory. After you solder the leads, the job is finished. There is no need for extra glue dispensing machines, curing ovens, or extra QC staff for the potting process.

Q5: What cable lengths and connectors are available for the TY806?
A: The standard length is typically 90cm or 120cm (customizable). We can equip the TY806 with standard MC4 or MC4-Evo2 compatible connectors. Please contact our sales team with your specific cutting and connector requirements.
