Hey gang
With the 215's on the scene and the tech literature on their website, they
state you can put up to 17 modules on a string.
Locally, I see folks throwing on 17-235 watt modules. Back of the napkin- 235
watts/240 volts = .97 amps.
17 x .97 = 16.49 amps on the 20 amp circuit. Pushing the envelop of the
circuit, per NEC and in situations of lower voltage, could tip the current
higher, per module it seems or is the unit current limiting?
Wouldn't it seem plausible to ebb on 16 vs the 17? The 15 amp circuit to 20 amp
circuit also is a change for the industry at large, as well as a few other
changes.
As Solarworld is rolling out their 250 watt and others in the same zone, it
seems there should/could be some caveats on the enphase literature to reflect
this.
Thoughts, comments?
