When you're wiring multiple solar panel strings into a single junction, the combiner box determines whether the job stays tidy or turns into a tangle of cables. Here, two options carry the same 4-string input, the same 63A circuit breaker, and the same $62.54 price. The real puzzle: which one should you order when the specs on both match?
Quick verdict Both entries are essentially the same solar balance-of-system component, built around a 4-string PV array input and a single string output. The one meaningful difference is the GDRASUYA10 entry's stated feature note: compact design, unique appearance, and high reliability. If that note matters to you, choose the GDRASUYA10 option. If you just need the core spec set at the same price, either entry will fill the same role.
Comparison at a glance
| Product | Price | Price Bar | Circuit Breaker | PV Input | Protection |
|---|---|---|---|---|---|
| NaMaSyo 4-String Solar Combiner Box | USD 62.54 | 63A, 550V | 4 strings in / 1 string out | IP65 | |
| GDRASUYA10 4-String Solar Combiner Box | USD 62.54 | 63A, 550V | 4 strings in / 1 string out | IP65 |
Where each option wins
- Choose the NaMaSyo 4-String Solar Combiner Box if the core essentials are enough: 63A breaker, four-string input, and IP65-rated housing.
- Choose the GDRASUYA10 4-String Solar Combiner Box if you want the entry that explicitly highlights compact design, unique appearance, and high reliability.
NaMaSyo 4-String Solar Combiner Box PV Combiner Circuit Breaker 63A For Solar Panel Kit
This white ABS/PC wall-mount unit takes up to four PV strings and combines them into a single output string. It includes one 63A, 550V standard circuit breaker, a 40KA/600V surge protection device, and an IP65 protection grade, with natural cooling for the 4-pole design. The NaMaSyo option is your pick when you want the standard configuration as described. The trade-off: because it matches the GDRASUYA10 option at the same price and same core specs, the NaMaSyo entry has no listed advantage if you were hoping one of the two would clearly separate from the other.
GDRASUYA10 4-String Solar Combiner Box PV Combiner Circuit Breaker 63A For Solar Panel Kit
This entry also provides four-string input, one-string output, a 63A/550V breaker, and the same IP65-rated, naturally cooled housing. What sets it apart in the specs is an explicit note calling out compact design, unique appearance, and high reliability. If those qualities are part of the reason you're choosing a combiner box, the GDRASUYA10 entry gives you a stated reason to pick it over the otherwise identical NaMaSyo option. The package contents for both options are the same, with each set including one combination lock and four mounting plates. The flip side: that differentiator is a listed feature description rather than a measurable performance claim, so the real decision still comes down to whether those stated qualities matter to you.
Final choice by use case If you're wiring four solar strings through one protected output and want the option that explicitly mentions compact design and high reliability, go with the GDRASUYA10 4-String Solar Combiner Box. If you're comfortable with the same core configuration and prefer the NaMaSyo entry, it will deliver the same junction-box setup. Since the two products share the same spec sheet and the same stated configuration, pick by stated features or merchant preference rather than expecting a difference between them.
