house

proposals

  • NewEnglandCleanEnergy proposal places 3x6 small pannels on porch (20V), and 1x6 on house roof over porch
  • with porch length extension from 44*5" to 48*5" - can use 340W pannels (24 total)

shed

  • Concrete Pour : https://www.youtube.com/watch?v=NGQll3R4gqI
    • min code based 2500psi
    • structurtual monolotichg - 3/4" graval & sand
    • admin : accel, retard, water reducers, air entrapment (free/thaw)
    • 5 types portland cement: 1-general
    • keep everything moist before the pour -
    • how wet - wet makes more time, but more seperation possibility
    • after bleed water is gone - smooth
    • knee boards (plywood with handels)
    • more times over - the more smooth

  • there is no 6" 12" area on roof to exclude solar panel - it is done due to panel recommendation
    • overhand is okay - so long as properly supported
  • shed - 400sf - no 48" mounting, but does need tie down
  • any structure that is walked under requires 48" foundation (eg 2 poles holding solar pannels)


NEC

PTS

SolarEdge

  • support : +1.510.498.3200 9am - 8pm EST
  • When connecting PV strings with power optimizers directly to a nonSolarEdge inverter without a Safety and Monitoring Interface, SafeDC must be disabled by the SolarEdge Key before connecting the string to the inverter. [1]
  • Can DC output of the SMI-35 be attached (simultaneously) to multiple devices (such as the input to the SE10000A

and TriStar MPPT 600V?

    • Figure 10 on Page 15 of the MAN-01-00067-2.1 discusses "SMI-Inverter

Connections". Here is shows that exactly only one SMI can be connected to a MPPT input. However the case of one SMI connected to two MPPTs or one SMI connected to a non-MPPT load and an MPPT load isn't discussed.


  • P400 max power - 85V, 15A?
  • Can use P600 and P700 in single phase system
  • How to get the SolarEdge Key
  • Can StoreEdge be used with 48V battery.

  "For good speech intelligibility, noise levels of less than 45 dB(A)…
   "[To avoid] sleep disturbance…a bedroom noise limit of 35 dB(A)…
   "General daytime noise levels of less than 55 dB(A)[to prevent] significant community annoyance…
   "To meet sleep criteria… [an outdoor level of] 45 dB(A)
    • There are electric blowers on the market today that are dramatically quieter than the typical gas blower, notably, the Blowhard rated at 56 dB and produced by Manutech
    • In three tests involving gas powered leaf blowers and battery powered leaf blowers, Diane cleaned the areas using rakes or brooms faster than any of the battery powered blowers and almost as fast as the gas powered leaf blowers and she did a better job in cleaning up the areas.
