How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For connectors, safety means stated certifications and ingress codes: all five state IP67, and three state CE plus TUV. Two of the five state a warranty term, a 24-month warranty and a 1-year warranty. How we pick explains the weights.

How to choose the best solar y connector for two panels
Match the current and voltage figures
Only two listings state electrical figures. The Bateria Power listing states 30A and 1000V DC, and the BougeRV ISE021 listing states 20A and 1000V DC. The other three state no current or voltage figure, so their capacity cannot be compared on paper. Read your panels’ stated current and voltage first, then pick a connector whose stated figures cover them. If you are still choosing panels, our best solar panel kit for RV roundup compares complete kits.
Read the certifications
Three listings state CE and TUV: the OYMSAE, Renogy and Bateria Power listings. The BougeRV ISE039 listing states TUV with tinned copper pins and PPO housing, and the BougeRV ISE021 listing states CE, RoHS and UL. The Renogy and Bateria Power listings also state UL94-V0 flame retardance. A stated certification is the main quality signal on a part this small, so weigh it heavily.
Check the cable fit and the pair count
Three listings state a cable fit of 14AWG to 10AWG: both BougeRV listings and the OYMSAE listing. The Renogy and Bateria Power listings state no wire gauge. On quantity, the OYMSAE and BougeRV ISE021 boxes hold 2 pairs, while the other three hold 1 pair. One pair joins two panels; the 2-pair boxes cover a second pair of panels or a spare. For the cable side of the job, see our 10 ft vs 25 ft solar extension cable comparison.
| Set | Stated current | Certifications | Pairs in box |
|---|---|---|---|
| OYMSAE Y Branch 2 Pairs | Not stated | CE, TUV | 2 pairs |
| Renogy Y Branch Pair | Not stated | CE, TUV, UL94-V0 | 1 pair |
| Bateria Power 30A Y Branch | 30A | CE, TUV, UL94 V-0 | 1 pair |
| BougeRV Y Branch 2 Pairs | 20A | CE, RoHS, UL | 2 pairs |
| BougeRV FMM+MFF Pair | Not stated | TUV | 1 pair |
Read the warranty lines closely
Only two listings state a warranty term. The OYMSAE listing states a 24-month warranty with a wrench included in the box, and the Renogy listing states a 1-year material and workmanship warranty. The other three state no term; the BougeRV ISE039 listing offers 18-month tech support instead, which is support, not coverage. For panel pairing questions, our MC4 extension cable picks cover more connector options.
Sizing Notes
- Match the connector’s stated current and voltage to your panels’ stated figures: 30A and 1000V DC on the Bateria Power, 20A and 1000V DC on the BougeRV ISE021.
- Check the cable fit: 14AWG to 10AWG is stated on the OYMSAE and both BougeRV listings.
- Check the stated IP code and certifications against your mounting spot: IP67 on all five, with CE and TUV on three.
- Count the pairs: 2 pairs in the OYMSAE and BougeRV ISE021 boxes, 1 pair in the other three.
