Amazon
- Non-UL [1]
- 250 VDC max input
UL Listed
- Combiner box only $250. [2]
- Only 125 VDC in.
Voltages
- 1000V for this one - [3]
- Why are others limited to 250V? Because the circuit breaker is 250V - [4]
- Go to Midnite for higher V combiners? [5]
- Most fuse holders are rated for 600-1000V, while DC breakers are 150V [6]
With 600VDC YRSP-D2 [7] circuit breaker - [8]. Combined wire is fatter, at least 10 ga. Circuit breaker appears to be 600Vdc rated [9].- 500VDC - [10]. Combined output appears to have 12 ga wire, or 20A max. Would need 10 ga for 30A combined output, so this is really only good for 20A.
Wire
- PV wire - [11]
Fuses
- Not cheap at $4 each [12]
DIY
