Choosing a charge controllers solar BOS component can become surprisingly difficult when two combiner boxes have the same four-string layout, circuit-breaker rating, and enclosure specification. Here, the useful decision is straightforward: select the TBvechi version when the lower listed price is the priority, or select GDRASUYA10 when that is the identified version you want for the same stated configuration.
Quick verdict
The two 4 String Solar Combiner Box PV Combiner Circuit Breaker 63A For Solar Panel Kit options are closely matched on the details that shape a four-array setup. Both are white, wall-mount units with four input strings, one output string, a 63A standard circuit breaker, and IP65 protection. Their listed-price spread is USD 3.12, so there is little reason to choose based on electrical layout alone.
For a cost-led decision, TBvechi is the clear pick. GDRASUYA10 is the alternative for shoppers who specifically prefer its listed brand identification while retaining the same core specification.
At-a-glance comparison
| Detail | GDRASUYA10 4-String Combiner Box | TBvechi 4-String Combiner Box |
|---|---|---|
| Listed price | USD 61.91 | USD 58.79 |
| Input and output layout | 4 strings in, 1 string out | 4 strings in, 1 string out |
| Circuit breaker | Standard, 63A, 550V | Standard, 63A, 550V |
| Protection layout | IP65; 2 surge protection devices rated 40KA, 600V | IP65; 2 surge protection devices rated 40KA, 600V |
Where each solar combiner box wins
TBvechi wins on listed price. Its lower figure is the only direct purchasing advantage between the two versions. The four-string input and one-string output design remains the same, so choosing it does not require moving away from the stated layout.
GDRASUYA10 wins for brand-specific selection. If the GDRASUYA10 identification is the version you intend to choose, it provides the same stated white enclosure, 63A breaker, and surge-protection arrangement as the TBvechi option. It is not a configuration upgrade; it is a like-for-like alternative at the higher listed price.
Product notes
4 String Solar Combiner Box PV Combiner Circuit Breaker 63A For Solar Panel Kit - GDRASUYA10
Choose the GDRASUYA10 version when that listed brand is the deciding preference and its four-array format matches the intended system plan. Beyond the shared breaker and protection layout, its specifications set a maximum input current of 10A for a single PV array and 40A total across the PV arrays. It also lists a maximum single-array input voltage of 1000V and a maximum output voltage of 600V. The white ABS and PC enclosure is described as wall mount, with an operating-temperature range of -30°C to 70°C. Its practical limitation is the stated natural-cooling design, which makes it a defined four-string combiner-box choice rather than a different configuration category.
4 String Solar Combiner Box PV Combiner Circuit Breaker 63A For Solar Panel Kit - TBvechi
The TBvechi version is the better fit when you want the lower-priced option without changing the stated four-input, one-output arrangement. It is also specified for up to four connected PV arrays, with the same 10A maximum per array, 40A total PV-array input current, 1000V maximum single-array input voltage, and 600V maximum output voltage. Like the other version, it uses a white ABS and PC wall-mount enclosure and lists operation from -30°C to 70°C. The main constraint is its fixed four-string input format: it is designed around that stated array count and one combined output, not a different input layout.
Final choice by use case
Pick TBvechi when the lower listed price is the key decision point and the stated four-string, 63A format suits the planned solar-panel system. Pick GDRASUYA10 when you specifically want the GDRASUYA10-identified version and its stated current, voltage, wall-mount, and natural-cooling parameters align with the same four-array application. For most like-for-like comparisons, TBvechi is the simpler choice because the central specifications match at a lower listed price.
