Mppt Mode Auto Track, Park Mpp Watts | Outback Power Systems 80

18. Advanced Menu (Micro-Hydro and Fuel Cell Applications)

Mpp Range Limit % (Auto Track Mode only)

The FLEXmax 80 searches for the MPP voltage by tracking the input voltage up to one half (default) of the Voc, which is based on values appropriate for a solar array. Micro-hydro and fuel cell systems can require a broader range, normally on the lower end. Adjusting the lower limit, expressed as 1/2 on the display screen, for FULL allows the FLEXmax 80 to track the input voltage close to the battery voltage instead of 1/2 (or 50%) of the Voc.

This adjustment only affects the initial tracking at the beginning of the day and any subsequent trackings caused by Auto-Restart or any forced restart of the FLEXmax 80.

To adjust the Lower Mpp Range Limit:

From the MAIN Menu, with the arrow in front of Advanced, press the <GO> soft key.

In the ADVANCED MENU screen, press the <NEXT> soft key until the Mpp Range Limit % Voc screen appears. Press the <1/2> soft key until FULL appears. When finished, press the <NEXT> soft key until the MPPT Mode screen appears.

To pick between Auto Track or U-Pick % MPPT Mode and determine the FLEXmax 80’s operating Voc percentage, press the <MODE> soft key to interchange between the two modes. Re-entering the password might be required. After choosing a mode, press the <NEXT> soft key in the ADVANCED MENU to view the Park Mpp screen (only applicable for U-Pickmode).

Press the <-VOC>or <+VOC> soft key to select one of the percentage values; U-Pickalways uses the Park Mpp value.
