Inverter Calculations
Each Inverter has the following values which are calculated following these formulas:
Inverter X:
{[((Temp Coef Voc) x (Voc)) / 100] x (Low Temp - STC Temp) + Voc} * (# Modules / String)
Inverter Powerwall 3 1707000-xx-y
Inverter Overcurrent Protection:
(Inverter(s) Max Combined Current) x (Continous Load) =
48A x 1.25+20 = 80A 80A Overcurrent Protection USING PCS
Wire ampacity calculated from 310.15(B)(16) & (17) as appropriate with ambient temperature calculations from
310.15(B)(3)(c) and raceway fill adjustments from 310.15(B)(3)(a). Conduit on the roof shall be installed no less than 1" above
the roof deck. PV Circuit conductor ampacity is constrained using the 75°C column with the continuous duty uprating or the
90°C column with the relevant ambient temperature and raceway fill adjustments without the continuous duty uprating per
690.8(B), whichever results with a larger wire size. Non-PV Circuit Conductors use the ampacity in the 75°C column or the
90°C column with the relevant ambient temperature and raceway fill adjustments, whichever is less (110.14(C) &
310.15(A)(2)). The rating of the conductor after adjustments shall be greater than, or equal to, the continuous duty uprated
current.
Calc Ex: Wire Ampacity x Ambient Temp. Corr. Factor x Conduit Fill Adj. Factor >= Output Current

Electronic Record and Signature Disclosure
CONSUMER DISCLOSURE
From time to time, Sunrun Inc. (we, us or Company) may be required by law to provide to you
certain written notices or disclosures. Described below are the terms and conditions for providing
to you such notices and disclosures electronically through the DocuSign, Inc. (DocuSign)
electronic signing system. PLEASE READ THE INFORMATION BELOW CAREFULLY
AND THOROUGHLY, AND IF YOU CAN ACCESS THIS INFORMATION
ELECTRONICALLY TO YOUR SATISFACTION AND AGREE TO THESE TERMS AND
CONDITIONS, PLEASE CONFIRM YOUR AGREEMENT BY CLICKING THE 'I AGREE'
BUTTON AT THE BOTTOM OF THIS DOCUMENT.
Getting paper copies
At any time, you may request from us a paper copy of any record provided or made available
electronically to you by us. You will have the ability to download and print documents we send
to you through the DocuSign system during and immediately after signing session and, if you
elect to create a DocuSign signer account, you may access them for thirty (30) days after such
documents are first sent to you. After such time, if you wish for us to send you paper copies of
any such documents from our office to you, please request delivery of such paper copies from us
by following the procedure described below.
Withdrawing your consent
If you decide to receive notices and disclosures from us electronically, you may at any time
change your mind and tell us that thereafter you want to receive required notices and disclosures
only in paper format. How you must inform us of your decision to receive future notices and
disclosure in paper format and withdraw your consent to receive notices and disclosures
electronically is described below.
Consequences of changing your mind
If you elect to receive required notices and disclosures only in paper format, it will slow the
speed at which we can complete certain steps in transactions with you and delivering services to
you because we will need first to send the required notices or disclosures to you in paper format,
and then wait until we receive back from you your acknowledgment of your receipt of such
paper notices or disclosures. To indicate to us that you are changing your mind, you must
withdraw your consent using the DocuSign ‘Withdraw Consent’ form on the signing page of a
DocuSign envelope instead of signing it. This will indicate to us that you have withdrawn your
consent to receive required notices and disclosures electronically from us and you will no longer
be able to use the DocuSign system to receive required notices and consents electronically from
us or to sign electronically documents from us.
All notices and disclosures will be sent to you electronically
Unless you tell us otherwise in accordance with the procedures described herein, we will provide
electronically to you through the DocuSign system all required notices, disclosures,
authorizations, acknowledgements, and other documents that are required to be provided or made
available to you during the course of our relationship with you. To reduce the chance of you
inadvertently not receiving any notice or disclosure, we prefer to provide all of the required
notices and disclosures to you by the same method and to the same address that you have given
us. Thus, you can receive all the disclosures and notices electronically or in paper format through
the paper mail delivery system. If you do not agree with this process, please let us know as
described below. Please also see the paragraph immediately above that describes the
consequences of your electing not to receive delivery of the notices and disclosures
electronically from us.

Wire ampacity calculated from 310.15(B)(16) & (17) as appropriate with ambient temperature calculations from
310.15(B)(3)(c) and raceway fill adjustments from 310.15(B)(3)(a). Conduit on the roof shall be installed no less than 1" above
the roof deck. PV Circuit conductor ampacity is constrained using the 75°C column with the continuous duty uprating or the
90°C column with the relevant ambient temperature and raceway fill adjustments without the continuous duty uprating per
690.8(B), whichever results with a larger wire size. Non-PV Circuit Conductors use the ampacity in the 75°C column or the
90°C column with the relevant ambient temperature and raceway fill adjustments, whichever is less (110.14(C) &
310.15(A)(2)). The rating of the conductor after adjustments shall be greater than, or equal to, the continuous duty uprated
current.

Electronic Record and Signature Disclosure
CONSUMER DISCLOSURE
From time to time, Sunrun Inc. (we, us or Company) may be required by law to provide to you
certain written notices or disclosures. Described below are the terms and conditions for providing
to you such notices and disclosures electronically through the DocuSign, Inc. (DocuSign)
electronic signing system. PLEASE READ THE INFORMATION BELOW CAREFULLY
AND THOROUGHLY, AND IF YOU CAN ACCESS THIS INFORMATION
ELECTRONICALLY TO YOUR SATISFACTION AND AGREE TO THESE TERMS AND
CONDITIONS, PLEASE CONFIRM YOUR AGREEMENT BY CLICKING THE 'I AGREE'
BUTTON AT THE BOTTOM OF THIS DOCUMENT.
Getting paper copies
At any time, you may request from us a paper copy of any record provided or made available
electronically to you by us. You will have the ability to download and print documents we send
to you through the DocuSign system during and immediately after signing session and, if you
elect to create a DocuSign signer account, you may access them for thirty (30) days after such
documents are first sent to you. After such time, if you wish for us to send you paper copies of
any such documents from our office to you, please request delivery of such paper copies from us
by following the procedure described below.
Withdrawing your consent
If you decide to receive notices and disclosures from us electronically, you may at any time
change your mind and tell us that thereafter you want to receive required notices and disclosures
only in paper format. How you must inform us of your decision to receive future notices and
disclosure in paper format and withdraw your consent to receive notices and disclosures
electronically is described below.
Consequences of changing your mind
If you elect to receive required notices and disclosures only in paper format, it will slow the
speed at which we can complete certain steps in transactions with you and delivering services to
you because we will need first to send the required notices or disclosures to you in paper format,
and then wait until we receive back from you your acknowledgment of your receipt of such
paper notices or disclosures. To indicate to us that you are changing your mind, you must
withdraw your consent using the DocuSign ‘Withdraw Consent’ form on the signing page of a
DocuSign envelope instead of signing it. This will indicate to us that you have withdrawn your
consent to receive required notices and disclosures electronically from us and you will no longer
be able to use the DocuSign system to receive required notices and consents electronically from
us or to sign electronically documents from us.
All notices and disclosures will be sent to you electronically
Unless you tell us otherwise in accordance with the procedures described herein, we will provide
electronically to you through the DocuSign system all required notices, disclosures,
authorizations, acknowledgements, and other documents that are required to be provided or made
available to you during the course of our relationship with you. To reduce the chance of you
inadvertently not receiving any notice or disclosure, we prefer to provide all of the required
notices and disclosures to you by the same method and to the same address that you have given
us. Thus, you can receive all the disclosures and notices electronically or in paper format through
the paper mail delivery system. If you do not agree with this process, please let us know as
described below. Please also see the paragraph immediately above that describes the
consequences of your electing not to receive delivery of the notices and disclosures
electronically from us.
