Nomura Configuration

Setting Vout_SNS using Input pot

Since we want to read the SPI values for the most useable range of inputs to the mppts, we are going to configure the input pot to read 1.0V on Vout_SNS for max voltage input (which should be around 20.44V for a 28 cell section).

The first step is to figure out what one turn refers to in terms of changing Vout_sns. I set the input voltage for the mppt to 20.44 V. I probed Vin_sns and adjusted the pot so that it equals about 1V. Essentially this pot adjusts the range of values while taking away from its accuracy. The following tests in spi will ensure that it covers a sufficient range for its predicted input voltage range.
