LEGAL DISCLAIMER
Xantrex does not provide solar array design advice as the charge controller
is a single component in a complicated and site dependent system. The webpage
you are about to access (the “Xantrex Sizing Tool”) is intended only as a guide
for Xantrex customers requesting assistance with array sizing. In no way is it intended
to be a guarantee of the performance of Xantrex inverter products or array compatibility,
and should not be relied on for solar array design advice for the reasons set out
below. It is the responsibility of the user of the Xantrex Sizing Tool
to confirm the correctness of the Reference inputs, the formulas behind the calculations
and the output of the Xantrex Sizing Tool. Xantrex recommends that in the design
of any system that a qualified installer be contacted to confirm the output of the
Xantrex Sizing Tool and the correct solar array.
There are a number of factors that may affect the output of the Xantrex Sizing
Tool or the appropriate use of a charge controller in an array design including,
but not limited to, the following:
A Xantrex charge controller will (i) shut down when DC voltage exceeds its rated
open circuit voltage (VOC), and if it does it will require a manual reset and may
even be damaged; and (ii) may not be able to maximum power point track (MPPT) at
voltages close to the battery voltage. Applications involving extreme temperatures
or low fill factor modules often push the limits of this specified voltage range.
This may mean that the controller only operates above the voltage at max power point
on the hottest days. The Xantrex Sizing Tool is heavily dependent on the accuracy
of the input data provided by the user and it does not account for module voltage
degradation over time. Xantrex also relies on module specifications provided by
the manufacturer of such module and can not guarantee the accuracy of such information.
THE USER OF THE XANTREX SIZING TOOL ACKNOWLEDGES that:
(i) The Xantrex Sizing Tool is being offered free of charge as a guide only and
is not to be relied upon as solar array design advice,
(ii) the warranty for Xantrex products is governed by warranty terms contained in
a separate Limited Warranty,
(iii) Xantrex makes no representation or warranty regarding the output of the Xantrex
Sizing Tool, and
(iv) the user agrees to use the Xantrex Sizing Tool at its own risk and with the
knowledge that Xantrex will not be liable to the user for any damages as a result
of use of the Xantrex Sizing Tool.
YOUR USE OF THE XANTREX SIZING TOOL CONFIRMS YOUR AGREEMENT TO THE ABOVE: |
